BACKGROUND

Commercial Kitchen Ventilation (Basic Theory):

Catering ventilation is made up of two main components – extract and supply. Kitchens produce heat and vapours that

need to be removed from the kitchen. The cooking processes produce particles (including smoke & grease) and heat that

need to be removed from the kitchen. Without mechanical ventilation, the kitchen would soon fill with smoke, become

hot and would be unbearable to work and be in. Furthermore, operating gas appliances produce gasses that are harmful

to health that must be removed from the kitchen. Building regulations also stipulate that kitchens (and other

environments) must provide a minimum level of air-changes (circulating ventilation) to deliver safe and comfortable

working conditions.

Kitchens are generally designed to include extract fans that provide forced air drafts (routed through ductwork) to pull

‘dirty’ air out of the kitchen. Extract canopies (sometimes referred to as hoods) are positioned over the cooking

appliances to ’localise’ the extraction in particular areas. There may be other extraction vents (grilles) in other areas of

the kitchen and/or building. Some special kitchen designs have extraction across the entire kitchen ceiling – otherwise

called a Ventilated Ceiling.

Commercial kitchens require powerful mechanical extract fans to deal with the by-products of cooking. If the extract

fan/s were the only ventilation, then there would be large drafts in the kitchen – through doorways, access hatches and

windows (etc.). The drafts would be strong enough to pull open swinging doors. In order to balance the air within the

kitchen, ventilation systems are designed to have supply fans that provide replacement (make-up) air that will balance

the pressure within in the ventilated environment.

In a kitchen, the supply ventilation must never deliver a greater air volume than the volume of air that is being extracted.

Ventilation designs will usually have the supply ventilation providing only 85% (make-up) air volume compared to the

extracted air volume (100%). The 15% shortfall in supply air will be ‘provided’ by air drawn naturally from the surrounding

environment (air-gaps, etc.). This way, there will be a slightly negative pressure within the kitchen that will pull the air out

of the kitchen, from under the canopy/s, via the extract ductwork – to be exhausted outside the building (on the roof, or

on the side of the building).

If a kitchen was to be over-supplied (more supply air provided than the air being extracted) then heat and vapours would

tend disperse away from the canopy/s. Air that should be extracted would spill into the kitchen area because the whole

space would be over-pressurised. Air will naturally flow from an area of high pressure to that of low pressure – if an

environment is all at ‘high’ pressure then there will be no direct path to the low pressure (the canopy filters and extract

ductwork).

Refer to the diagram showing the extract & supply ventilation and the natural (15%) air draw, creating a negative-

pressure environment.

Basic Catering Ventilation Design Theory

The extract ventilation will be ableto provide 100% duty (demand)requirements, based on the kitchendesign and installed appliances.

The supply ventilation willprovide 85% make-up air,based on the extractventilation design (duty)specification.

The 15% difference(between supply &extract) will be'supplemented' byfresh-air drawnnaturally from theenvironment - throughcracks in door, etc.

100% = 85% + 15%EXTRACT

VENTILATIONSUPPLY(MAKE-UP)

VENTILATION

NATURALDRAFT

If you look at the area being ventilated as if it was a closed cardboard box with a certain volume of air being extracted

from the box and 85% of that volume being replaced as make-up air, then the outstanding 15% would be drawn-in

thorough the cracks in the box base and lid. This situation would produce a negative pressure within the box and is the

how a kitchen ventilation system should work, because all of the air entering the box would have no other option, but to

be extracted through the extract system. If the box was to be over-supplied, with more air being supply than was being

extracted, then the ‘dominant control’ of the extract system would be lost.

The importance of balanced system will become more crucial when there are openings (serving hatches, for example) to

adjacent areas, such as restaurant seating areas. In particular, if there is a theatre-style (display) canopy between two

ventilated areas, and a catering appliance at the ‘dividing line’, then the system needs to be very well balanced between

the two areas, otherwise smoke (and/or other cooking vapours) can easily be blown into either the kitchen or into the

seating area.

Quintex expects new-build ventilation systems to be fully balanced by the (commissioning) ventilation contractor. Quintex also expects (and assumes) that pre-existing ventilation systems are fully balanced before the Cheetah system is installed to a kitchen and will set-up a new Cheetah system assuming that the ventilation system has the correct balance. If a ventilation system lacks the correct balance (but has the capability of meeting the ventilation requirements for the area) then specific limits and signal scaling can be applied to the Cheetah system, at the commissioning stage, in order to provide the correct ventilation balance across the active range of operation.

Overview: The Cheetah system is a DEMAND BASED VENTILATION CONTROL SYSTEM that is designed to be installed in commercial kitchens to automatically control the speed of the catering ventilation fan/s. The system uses temperature sensors, mounted in the extract canopy ventilation ductwork (spigot/s), to control the fan speed, by using AC variable frequency inverter drives installed to the ventilation fans. The system also uses specially designed optical sensor equipment (where required) to detect steam and/or smoke. The system uses a (self contained) digital-bus-network (LonWorks protocol). All of the main Cheetah system components communicate with each other via the digital network. The Cheetah system is designed to be autonomous control system. However, when required, Cheetah can also accept additional external commands from other building control signals – for example, fan operating-period timer controls – from an external source.

Cheetah System Components: Cheetah (C3) Display:

Cheetah CUB display: 155mm x 135mm x 50mm

The Display unit is usually mounted on a wall in the kitchen (but it can also be installed in a ‘back-of-house’ are or in an office). It is used to display information relating to the running of the system - including; operating fan speed/s, active duct temperatures and general system faults. The display has a two user buttons. One button allows ‘System Override’ (at the full VFD set-speed) to be activated for a preset time. The default system override time is set to 1hr, during which time a (RED) Max Rate (LED) will be on. After the (preset) override duration, the system will revert to normal demand operation and the Max Rate light will switch- off. In normal operating mode; the Cheetah Display will have the (GREEN) POWER ON (LED) light illuminated. There will be a (BLUE) POWER SAVING (LED) light on when the fans are running below 100% operation. The display unit alpha-numeric display will show the current status of the system. Pressing the SCROLL button will show the details for the fan/s being controlled on the system. Further pressing of the scroll button will show other ‘installed’ fan details.

Sensor-Processor Unit:

Cheetah sensor-processor: 190mm x 120mm x 60mm

The sensor-processor unit (sens-proc.) is installed out-of sight (usually located above the ceiling – above the extract canopy). All of the temperature sensors and optic sensors plug into the sens-proc. unit. The unit is connected onto the LonWorks digital communications bus network. For more complex ventilation systems (where many canopies are attached to a single extract fan) up to 4 sens-proc. units can be installed, per Cheetah system, to a single Display unit.

Temperature Sensors):

Temperature Sensors: Cheetah temperature sensor:

190mm x 120mm x 60mm

The Cheetah system detects heat within the kitchen extract canopy plenum/ducts by means of digital temperature sensors. The temperature sensors are usually installed at the mouth of each duct within the extract canopy/s (where the optimum canopy temperature measurement can be obtained and where the sensors are accessible, for cleaning). Up to 4 temperature sensors can be installed to each sensor-processor unit. Cheetah temperature sensors are accurate digital thermal devices that produce absolute temperature readings. As the temperature sensors measure the temperature of the extracted air – the fan speed/s will respond (proportionally) to the temperature (increase), depending on the system set-points. Thermal control is fundamental to the operation of the system and is often the basis for maintaining the required ‘active’ fan speed running level.

Optic Sensors (emitter & receiver):

Cheetah optic sensor (pair): 190mm x 120mm x 60mm

The Cheetah system is designed to operate with Cheetah optic sensor units (the optics are bespoke and no other standard, ‘off-the-shelf’ sensors will operate with Cheetah). Likewise, the Cheetah sensors will NOT operate without a Cheetah system. The sensors connect to the Cheetah sensor-processor unit by plugging into the optic ports (two available ports). Optic sensors are (usually) installed to the inside ends of the canopy/s and they constantly scan the length of the canopy/s to detect steam/smoke activity.

NOTE: ensure that the optic unit/s is plugged-in to the OPTIC port on the Sensor-Processor unit.

Be carefull NOT to plug an optic sensor into the NETWORK port as this will

cause damage to the sensor-processor unit and/or the optic unit. Likewise DO NOT plug a network signal cable into any port other than a NETWORK port.

Cheetah optic-sensor-units are installed to the extract canopy/s in the areas where they are required. In some rare cases, due to canopy design, the optic sensor/s may need to be positioned in other locations. It is important that canopies situated above appliances that produce quantities of steam and/or smoke have Cheetah optics installed. Some catering appliances are very well thermally insulated and they therefore to not generate heat that will register on the temperatures sensors. These appliances will often produce a large burst steam or smoke when they are opened/accessed – it is imperative that these appliances are covered by optics that will trigger the fans to run to full-speed, on demand.

Vacon AC Inverter Drives:

Vacon 100: frame MR4: 328mm x 190mm x 128mm frame MR5: 419mm x 214mm x 144mm frame MR6: 557mm x 229mm 195mm

Each canopy ventilation fan (that is being controlled) is installed with a Vacon100 three-phase AC Variable Frequency Drive (VFD). The VFDs that are supplied by Quintex have a bespoke software application and specially designed Cheetah network interface circuitry installed. A standard (off-the-shelf) VFD will NOT work correctly with the Cheetah system. The Cheetah system communicates (via LonWorks digital communications) with the inverter drive, to instruct the required inverter running frequency/speed. Digital communications are also fed back from the Inverter/s to the Cheetah system, thereby 'reporting' the real-time operational status and running speed (frequency) of the ventilation fan/s.

Extract Fan Inverter (VFD): Based on the demand (canopy conditions) the Cheetah system will calculate the required running speed of the extract fan/s that is connected (configured) to the Cheetah system. The commanded running speed will be sent (via LonWorks digital communications) to the extract fan inverter – the VFD will feed back an actual running speed (frequency) to Cheetah.

Supply Fan Inverter (VFD): Depending on the running speed of the extract fan VFD/s that is fed back to Cheetah, the supply fan VFD will be sent the same speed instruction as the extract fan (or the extract fan with the highest demand when there is more than one extract fan being controlled). In order to maintain negative air balance – the Cheetah system will not send a supply fan instruction that is higher that the commanded extract speed. If required, specific scaling can be applied to the commanded supply (and or extract) speed to produce higher supply fan running speeds (for example, this type of operation may be required if a ventilation supply fan is undersized, compared to the extract fan).

Variable Frequency Drive (Basic Theory): The diagram below shows a very simplified layout of a typical VFD design. On the left (L1, L2 & L3) are the terminals where the input electrical power is connected. A three-phase rectifier circuit converts the incoming AC voltage to a DC (Bus) voltage (held a constant level at points P+ and N-). The output section (terminals – U, V & W) of the VFD is controlled by complex electronics that control substantial, fast acting IGBT power transistors which produce the required output voltages. Sophisticated control electronics precisely control the operation of the output transistors (that switch thousands of times per second) in order to produce the required output. This operation notoriously creates strong harmonic waveform effects that must be considered when installing this type of electronic switching equipment.

INPUT OUTPUT

By adjusting the VFD output frequency, motors that are connected to the devices can be precisely speed controlled. The Cheetah system senses the catering demand and adjusts the frequency so that the motor speed adjusts in proportion to the level of cooking. Due to the very high frequency electronic switching operation of a VFD, the potential for the installed device to generate serious electrical noise on power cabling is very high. This is true of all VFD designs, regardless of who manufactures them. If a VFD was installed, using standard electrical installation techniques (as you would with motors installed direct-on-line, which a motor with no speed control, directly powered by 50Hz mains voltage) then several issues could be experienced.

These issues include:

Noise emissions contravening EMC regulations (The emissions will affect other electronic equipment – including Cheetah)

Damage to the VFD (that can be destructive).

Damage to the motor (that can also be destructive). Quintex has well defined installation procedures that follows the advice from GAMBICA (The Association for Instrumentation, Control, Automation and Laboratory Technology in the UK) when installing VFDs to fan/motor equipment.

Main Quintex VFD installation policies:

Install the VFD as close as possible (Quintex attempts to install a VFD within 2m of a motor that is being controlled, in order to minimise potential issues).

Always install with VFD-grade (SY - Sylflex) cable (or using similar, existing armoured shielded cable). Installed in such a way as to prevent ground-loop issues.

Ensure that there is a good ground connection to the VFD and the shielded SY-cable in order to attenuate (and dissipate) any emissions and/or voltage spikes that may be produced. Voltage spikes have the potential to harm equipment.

Data Logger (RCDLU):

Cheetah data-logger: 190mm x 120mm x 60mm

Each Cheetah system is installed with a dedicated Cheetah Remote Communications and Data Logging Unit. Equipped with internal memory, the logging unit can be set-up to log any required (LonWorks) system parameters (including –Inverter, Sensor-Processor and Display unit parameters). In addition to being able to log parameters, the Data-Logger is equipped with a GPRS modem (and a data-enabled SIM card). This allows Quintex to remotely dial-in to any installed Cheetah system to monitor, adjust and diagnose systems, as required. The data-logger should be located in a suitable position where there is a good GPRS signal. The diagram below shows the status lights (LED) that are on the side of each data-logger unit. When the Cheetah display unit is powered, the data-logger will power and the status can be checked. All three LEDs should illuminate to indicate that the unit is powered, memory initialised and connected to a GPRS signal. The best location for installing a Cheetah data-logger will often be on the roof (when the fans are located there). Data-loggers are generally installed alongside an inverter (within the enclosure, when applicable). It is fixed in position with screws (a screws though each of the side slotted mounting ‘tabs’). The data-logger should (ideally) be installed before the first or second VFD (unless the is in a poor reception location – for example in a basement plant-room). The cable length between the Cheetah Display unit (in the kitchen) and the data-logger should NOT EXCEED 60m.

Cheetah Data Logger status LEDs

The Cheetah data-logger has three status LEDs.

RED - when the data-logger is powered the red LED will illuminate.

GREEN - shows that the data-logger has connected to the wireless (mobile) network.

YELLOW - is lit when the internal (SD) memory card is installed and initialised

Cheetah system modular design: The Cheetah system is designed to be modular so that it can be adapted to virtually any ventilation system that it needs to control. Any number of Sensor-Processor units (up to a MAXIMUM of 4) can be added to a Cheetah system depending on the requirements. EACH SENSOR-PROCESSOR unit can directly control ONE EXTRACT (FAN) VFD – additional VFDs can be (analogue) SLAVE controlled, as required. EACH Cheetah DISPLAY UNIT (the entire installed Cheetah system) can directly control ONE SUPPLY (fan) VFD – additional VFDs can be (analogue) slave controlled, if required. The main system components are all LonWorks based. When configured, these devices will ‘bind’ together to form an inter-dependant network. Any disruption the network will highlight faults, errors or warnings within the Cheetah system. The LonWorks devices in a Cheetah system are as follows:

Cheetah Display unit

Cheetah Sensor-Processor unit/s

Cheetah RCDLU (Data-Logger) unit

LonWorks compatible VFD

Cheetah Input/Output (mini-GPIO) unit (is specialist D-to-A interface not used in sub-contractor installations.)

INSTALLATION OF THE CHEETAH SYSTEM EQUIPMENT

GENERAL CONSIDERATIONS: Cheetah installations must be installed so that the systems are robust and reliable. Systems are installed with the intention of lasting several years; they need to produce savings for the client during the period when they are recovering the initial financial investment and for many years thereafter.

Cheetah NETWORK, OPTIC and TEMPERATURE (signal) cables must not be run next to power cables. A separation of at least 150mm must be kept between mains-power and signal cables. Any signal cables that need to cross power cables should do so at 90 degrees (in order to keep the contact between the two types to a minimum – this is to keep potential contamination of the signal, induced from the power cables, as low as is possible).

Cables must NOT be run in extract plenums, chambers, voids or ducts. Short sections of cable that need to transfer through shorts sections of ductwork (etc) MUST BE PROTECTED with suitable grease-resistant steel-lined-conduit (this option should only be a last resort - when there is no other options available for running cables. All through-holes, where cables pass though, must have grommets/glands (or similar) to protect all cables that are installed.

The optic units must be installed as designed; with conduit tubes, collars, stainless-steel washers/covers, and stainless steel fastenings. The installed unit must produce a sealed unit (from stop to bottom) so as to to repel any potential ingress of grease, dust, moisture or other contaminants. NOTE: There are some canopy/kitchen layouts where the optics may need to be close-coupled (flush mounted) to the canopy top-skin – however, this method must ONLY be used in those special cases (when there is no other viable option of optic installation available). Makes sure that optic locations are correctly measured so that the optics are level and the optic-conduit-tubes are in parallel to canopy edges/etc (i.e. not askew). Make sure that you use the plastic mould caps cable-tied in place, on the top of the optic assembly when installing.

Ensure that all canopies associated with fan are connected to the Cheetah system – for example, if a Preparation Kitchen canopy is linked to the Main Kitchen extract fan, then make sure that it is installed with sensors (and an additional processor, if/as necessary) so that it can also provide control to the ventilation fan/s.

Make sure that the Cheetah Display unit is level and that the cable-trunking is neat and tidy – this is often the most visible part of the Cheetah system (with the Quintex name on it) – make sure that it looks presentable.

The SY (Sylflex) cable screened must always be EARTHED at one end (standard practice at Quintex, is to earth the screen at the VFD. There must be a separate EARTH conductor/core connected to drive and motor). Produce the required electrical test certificate for the wiring installation for each VFD installed.

Don’t run cables in exposed areas. Outdoor cables must be run in suitable copex/conduit. Keep temperature and optic cables away from hot canopy tops and duct-work (etc) to prevent them from being damaged.

Make sure that a good EARTH connection is made to the Sensor-Processor unit on each and every installation. The earth connection is generally made to the extract canopy (which should be well EARTHED) either with a mounting plate or a fixed electrical cable to the sensor-processor unit.

NOTE: only motors with winding insulation rated at Class F (1550C) or greater are suitable for control with VFD equipment. Class A (1050C) Class E (1200C) & Class B (1300C) are all UNSUITABLE to be controlled by a VFD.

CHEETAH DISPLAY INSTALLATION: The Cheetah Display unit is usually mounted on a suitable wall in the kitchen (but it can also be installed in an office or other preferred location). For new-build installations, there is often a position agreed (before the installation begins), with the kitchen designer, architect, job foreman (or similar authority). The diagram below shows the most common location of an installed display unit. The fused/switched spur is usually fed from a dedicated (5A) MCB – labelled as Cheetah. For new-build site installations the requirement for the circuit should be requested before the installation, so that it can be included in the electrical Distribution-Board design. The Cheetah display (which also provides power to the other components on the network –except for the VFDs that have their own 3-phase power supply) is rated at 2A.

Plastic Trunking[100mm x 50mm]

Position (approximately)2m from floor level(to the base of the unit).

Positioning Cheetah Display unit

Mount the Cheetah Display unit on the wall. If there is no other agreed instruction, the guidance height for the installation of the unit is 2m from the floor level. Of particular importance is where the network and power cables pass through the ceiling, to the void. Ensure that there is enough clearance on the ceiling penetration (or ceiling tile) so that the cables are not pinched, chafed, punctured, stretched or damaged. De-burr and remove any sharp edges/points. The Cheetah one-page (Quick Reference Guide) should be positioned next to the display unit – clean the surface and dry thoroughly before applying self-adhesive the label.

The Cheetah CUB display front panel has 4 screws that fix it to the main body. You will need a T-20 (Torx) bit to remove and replace the front panel on the unit. Unscrew the four screws and lift the lid with care. NOTE: There is a ribbon-cable that links the front panel to the circuitry within the main unit. CAREFULLY unplug the ribbon-cable to detach the front from the body. There are four mounting-slots in the rear of the main unit (see the dimensions of the mounting slots in the diagram below). The display is generally wall mounted, using suitable wall-plug-fixings and screws to hold the unit in position. Likewise, the (100mm x 50mm) plastic trunking is installed (with wall-plug-fixings and screws) directly above the Cheetah display, up to the ceiling level. Cables are run up to the ceiling void above, contained within the plastic trunking. After the main body has been wall mounted, wire-in the single-phase power to the relevant terminals (EARTH, LIVE & NEUTRAL). Carefully reconnect the ribbon-cable, with the same orientation as it was removed. Replace the front panel onto the display and tighten the four Torx screws.

4 (off) 4mm keyhole slotsare available on the rearof the display unit.

Cheetah optic sensors (mechanical installation): Before installing the optic sensors, assess the extract canopy for the best placement of the equipment. Choose an optic sensor location that will allow a clear view down the length of canopy and that will be in the path of steam/smoke that is drawn to the filters. Avoid sensor location/s where there are items that will interfere with the laser signal – including:

Canopy light fittings

Fire suppression jet/nozzle assemblies

Canopy (partition) sub-dividers or support struts

Catering appliances

Steam exhaust vents from catering appliances

Other obstructions

Check the area above the canopy has clearance to allow the optic collar, tube and cabling to installed.

Cheetah optics sensor assemblies must be installed as designed (as shown in the diagram) in order to ensure the reliability and longevity of the sensors. The assemblies must be protected for dust, dirt grease & moisture ingress by fitting the PVC protection cap on the end of the optic tube – the cap and cable are secured in place using a cable-tie. USE (A2 STANLESS-STEEL) M5 x 8mm SLOT PAN-HEAD SCREWS AND (A2 S-ST_ M5 DOME NUTS TO FIX THE SENSORS IN POSITION [4off SCREWS & NUTS PER OPTIC HOUSING]. OPTIC COLLARS ARE SUPPLIED WITH THE FIXINGS INSTALLED.

Optic Housing The stainless-steel enclosure that houses the working electronic components of the sensors

Optic tube (conduit) The stainless-steel tubes where the cables run from the optic housings to the area where the sensor-processor is mounted

Optic collar (conduit support) A circular nylon ring and stainless-steel (cover) washer that holds each optic tube in position (the washer is visible from the underside of the canopy). The collar has a locking grub-screw that can be used to lock the tube in position (as required).

Optic (PVC) protection cap The protection cap is a dip-moulded cover that is installed at the open end of the optic tube to stop contaminants entering the internals of the optic assembly.

Other examples of optic sensor installation: Generally, new-build installations are installed using the standard methods (detailed in the previous pages). There are canopy constructions where a ‘standard’ optic sensor installation is not possible. For these cases, there are other possible formats of sensor installation that can be implemented. These include:

Installation of sensors with optic tubes perpendicular (90 0) to the filter face.

Installation of sensors into clean chambers (eg. the supply plenum) within the canopy.

Installation of sensors enclosures external to the canopy external enclosure/s and cable trunking/conduit.

Installation of sensors close-coupled (flush-mounted) to the canopy top (without an optic tube).

Installation of sensors to walls and/or pillars (with or without bespoke brackets or ‘cranked’ optic tubes). The diagram below shows a Cheetah optic sensor installed at 90 0 to the canopy filter-face. This method could be used if there was an obstruction above the front part of the canopy, with access still available at the rear. Only suitable flexible-hose (with good heat and grease tolerant properties) should be used to make the connections between the fixed optic tube sections. In the diagram, the flexible-hose is labelled as flexi-tube. A modification of this installation could have the tube and cabling (with the use of flexible-hose) exiting out the rear of the canopy – if (for example) there was a solid concrete ceiling above the canopy.

19


quintex.co.uk

The diagram below shows another possible installation format for an optic sensor. In this case it shows a canopy that has been installed in an area where there is neither access to the top, nor the rear of the canopy. Therefore, the optic sensor can be installed with a (stainless-steel – hermetic) dairy-tube elbow-fitting, optic-tube sections and a (stainless-steel) enclosure, external to the canopy. The Sensor-Processor is shown mounted within the enclosure. In this case, suitable trunking would be installed to allow cables to run outside of the canopy/s. It is unlikely that a new-build installation have a canopy (as shown) installed in this manner, but there may be other factors (in rare cases) that may require optics to be installed in the same (or similar) way to what is shown in the diagram.

NOTE: For a canopy that has restricted accessibility to the void above it – access, can often be made via the canopy light panel/s (fittings), allowing optic-collars & optic-tube-covers to be installed and for cables to be run. Thereafter, light panels can be reinstalled. If canopy construction allows, removable canopy front panels can also allow access if required.

Optic Sensor Cabling: When the optic sensors have been fixed in the respective positions, the sensors are wired-in to the Cheetah sensor-processor (s/p) unit as shown in the diagram below. A CAT5 cable plugs into the OPTIC PORT on the sensor-processor. Remove the protective RJ45 connector barrel assembly from the other end of the cable. Feed the cable down the optic tube (into the RECEIVER housing) and plug it into the RJ45 socket on the RECEIVER pcb. Use an RJ12 (telephone-style) cable to link from the RECEIVER pcb, across to the EMITTER (laser) pcb.

Optic Sensor Selector Switch: When installing two optic sensor units (pairs) to a single sensor-processor unit, then the selector switch on the receiver unit MUST be set to a different position, on the two units. Hence,

On ONE OPTIC RECEIVER PCB – the switch MUST be in the ‘UP’ position

On the OTHER OPTIC RECEIVER PCB – the switch MUST be in the ‘DOWN’ position. This is so that the sensor-processor unit can identify that there are are two sets of optics installed and so that independent signals from each optic are received by the processor, to be dealt with (If the switches are both in the same position, then they will not register as two sets and the Cheetah system will NOT work correctly). If only ONE SET of optic sensors is being installed to a sensor-processor unit, then the switch position is not important (either ‘UP’, or ‘DOWN’ will work correctly).

Temperature Sensor Installation: Up to 4 temperature sensors can be installed in each sensor-processor unit. The temperature ports on the sensor-processor unit are labelled 1 to 4. For simple canopies (with one or two extract duct spigots) a temperature sensor can be installed in each extract duct spigot, at the mouth of the duct in each case (refer to diagram below). The RJ12 temperature cables run back to and plug into the sensor-processor unit (one for each sensor). The cables should be run so that they do not contact with hot surfaces (like some areas on top of the canopy) and should be routed where they are out of the way of damage, from people that access the area above the canopy. Beware of sharp edges and rough through-holes that could damage the cables. For more complex systems specific spigots where there appliances installed beneath will be installed, with other areas (for example – preparation counters) not requiring a temperature installed in that area. Be careful when installing a temperature sensor directly above an appliance that has a very high heat output (for example when installing above a char-grill unit/s or above fryer heat vent outputs). In these cases, it is better to install the temp/s a further down the duct, so that the air temperature has some time to cool-off a little before it is sensed by Cheetah. The specification of the Cheetah temperature sensor is rated up to a MAXIMUM of 80 0C.

The physical installation of a temperature sensor is generally a quick and simple task. Using a battery (or a suitable wired) drill and a hole saw (recommended between 28mm and 32mm diameter). In line with the notes on the positioning of temp sensor (previous page), locate a section of ductwork that is away from a join or strengthening-rib section (and free from other obstructions) and drill a through hole. Through newly drilled the hole, install the sensor assembly as shown in the diagram below. Once assembled, use suitable spanners (adjustable spanners or pipe-grips) to tighten the locking nuts on the temperature sensor, so that it securely fixed in place. After the RJ12 cable has been connected to the sensor, a small ‘loop’ is put in the cable and then it is cable-tied to the sensor, to prevent strain on the connection, if the temp cable were to be inadvertently pulled.

When installing a temperature sensor, bear in mind that the unit will have to be periodically accessed for service and maintenance. When operating normally, temperature sensors are serviced by wiping any grease build-up from the sensor. The cleaning is mostly performed on the sensor tip where the duct air temperature detection takes place.

Cheetah Sensor/Processor Unit (earth-strap) The sensor-processor unit is a local hub device that accepts the temperature sensor and optical sensor inputs. It can be seen as the system ‘brain’ that processes the received signals and computes the running-speed for the fan associated with the canopy/s where the sensor equipment is mounted. The unit should be located in a position (usually above the canopy) where is will not get damaged by other people (engineers) accessing the area. It should not be positioned in a location where is will be exposed to excessive heat, moisture or vibration. For new-build installations, the sensor-processor will be supplied with a sensor processor mounting plate. Attach the mounting plate to the rear of the sensor-processor unit using four M4 (x10mm) screws. The unit can then be fixed in a suitable position (out of harms’ way) where the sensor and network cables can lead back to, to be plugged-in to the relevant ports.

FOR ALL INSTALLATIONS:

IF THE SENSOR-PROCESSOR UNIT IS MOUNTED DIRCTLY ONTO THE CANOPY – NO FUTHER ACTION IS REQUIRED. (keep the sensor-processor mounting position away from areas of high heat that could affect the unit).

IF THE SENSOR PROCESSOR UNIT IS NOT MOUNTED DIRECTLY TO THE CANOPY THEN YOU MUST

CONNECT AN EARTH-WIRE BETWEEN THE SENSOR PROCESSOR UNIT AND THE CANOPY METALWORK. (Use one of the M4 screw threads at the back of the sensor-processor unit where

the earth-wire can be attached using a ring or forked-spade connector).

Variable Frequency Drives (VFD) - selection: The Cheetah system is designed to fully integrate with the Vacon 100 range of Variable Frequency Drives. It is the primary type of VFD that is specified by Quintex to allow the Cheetah system to operate to its full design potential. The VFD requirements, for the motors that are being installed with Inverter drives should have been surveyed, specified and ordered prior to the installation of the Cheetah system. Make sure that the correct VFD is installed to the correct motor/s by following the selection and installation processes of VFDs detailed below. Vacon 100 VFDs are available in two different main insulation classes, IP21 & IP54. An IP21 VFD must always be installed with a protective enclosure (in order to meet legal EMC & safety requirements) and are specified for VFDs installed external to a building (usually this is when fan equipment is located on an outside roof area). Quintex have designed draft-ventilated enclosures into which Vacon100-IP21 VFDs can be installed. The enclosures must be (draft) ventilated, or else the heat dissipated whilst the VFD is operating will soon raise the ambient air temperature with the enclosure until it exceeds the operating temperature of the VFD – at which time the VFD will stop operating. Likewise, it is important that only one VFD gets installed in each enclosure, to meet the thermal requirements of the VFD. An IP54 VFD is designed to be installed, internal to a building (within a plant-room) and does not require an additional enclosure. When choosing the enclosure, use the following selection table to choose the correct size enclosure to match the thermal requirements of the VFD.

VACON 100 IP21 VFD SIZE (CURRENT RATING) QUINTEX (VENT) ENCLOSURE SIZE

3.3A (FRAME-MR4) 4.3A (FRAME-MR4) 5.6A (FRAME-MR4) 7.6A (FRAME-MR4) 9.0A (FRAME-MR4)

500mm x 400mm x 260mm

12A (FRAME-MR4) 16A (FRAME-MR5) 23A (FRAME-MR5)

600mm x 600mm x 300mm

Larger sized VFDs will require a larger (bespoke build) enclosure. In general larger fan motors are more likely to be plant-room based

and will be suitable to be installed IP54 VFD, without enclosure

26


quintex.co.uk

VFD SELECTION PROCESS:

When installing a VFD to a motor, the unit has to be CORRECTLY sized. This is done by reviewing the motor plate details to obtain the full-load-current and specifying a suitable VFD to run a motor of that size.

Every motor is fitted with a manufacturers’ rating (specification) plate – the plate will detail the essential specifications of the motor and will also provide the correct terminal wiring configuration for use at 400V operation.

Find the Full-Load-Current rating for the 400V operation for the motor (the rating could also be listed as a range between 380V-415V).

Use this FLC rating to select a VFD that will provide 110% of the FLC value.

The image of the rating plate below is from a Brook-Crompton motor. Refer to the 50Hz specification that describes:

1.5kW 1400 revs per min 380-415V 3.6-3.4A

THE MOTOR SHOWN MUST BE WIRED TO STAR CONFIGURATION (other motors may differ) [Refer to the rating plate below – 50Hz V rating symbols 220-240V (delta) / 380-415V (star = Y)]

In this case, a VFD should be selected that will provide the required current of 3.4A (at 415V) 1.5kW. Therefore – select a 4.8A VFD to install to this motor.

When entering the key parameter information to the VFD (as per the VACON 100 -installation/commissioning procedure that is detailed later in this manual)

The VFD should be set to a Motor Nominal Current (Mot Nom Crrnt) of 3.4A.

The VFD should also be set to a Current Limit of 3.7A.

DO NOT INSTALL A VFD THAT IS UNDERSIZED MAKE SURE THAT IT WILL PROVIDE (AT LEAST) THE MOTOR FLC+10% [and satisfy the kW rating].

27


quintex.co.uk

Depending on where the VFD is to be mounted, select the required VFD from one of the two tables below. Both tables show the same incremental VFD sizes (in the rating column, in BOLD) match this to the motor FLC,

One table is for IP21 units & the other is for IP54 units these numbers will be printed on the VFD packaging box.

Vacon 100 - Variable Frequency Drives (VFD) Installation: Each Inverter unit is installed in-line with the 'pre-existing' 3-Phase electrical power supply, and should be located near to the motor that is being controlled (after the local motor electrical isolator). Inverters are mounted in the most suitable locations, these include; position; on the side of Air-Handling-Units (if external, mounted in a suitable enclosure), on kitchen/corridor/plant-room walls or within electrical control panels.

STANDARD QUINTEX POLICIES FOR THE INSTALLATION OF INVERTER (VFD) EQUIPMENT:

INVERTER UNIT SHOULD BE INSTALLED AS CLOSE TO THE FAN/MOTOR EQUIPMENT AS IS POSSIBLE: Ideally it should be installed within a 2m cable length, where feasible.

USE SUITABLY RATED SCREENED (Sylflex) SY CABLE For THREE-PHASE – it is a 4-CORE (3-LIVE CORES+1 EARTH) CABLE

Inverter output power cables MUST NOT be installed with single (unscreened) cables. Refer to the Vacon 100 installation manual for the correct cable size rating for each VFD/motor installation.

THE EARTH CONDUCTOR CORE/S MUST BE CONNECTED THROUGHOUT THE WHOLE CIRCUIT You must verify that there is an earth connection, at the motor – without a good EARTH connection,

the installation will be unsafe and the VFD will be at risk of being damaged.

THE (SY) CABLE SCREEN MUST BE CONNECTED AT ONLY ONE END (SO AS NOT TO CREATE ANY POTENTIAL EARTH/GROUND LOOPS.

Qunitex (typically) connects the SY-cable-shield at the inverter end and leaves it un-connected (but safely insulated) at the motor end. Refer to the diagram below the method used to install a VFD.

NOTE: Choose the correct motor terminal (rating) configuration for the inverter being installed. Refer to the motor plate for the correct voltage configuration.

THERE MUST BE NO OTHER ELECTRONIC DEVICES IN THE (INVERTER) ELECTRICAL CIRCUIT:

Any other electronic inverters, soft-starters, modulators, etc will affect the operation and damage the inverter.

29


quintex.co.uk

THE VFD ELECTRICAL SUPPLY MUST NOT HAVE A STAR-DELTA STARTING SEQUENCE: The VFD must have Direct-On-Line voltage ONLY – this will be 3 constant phases L1, L2 &L3 (neutral not required).

SELECTING THE CORRECT MOTOR TERMINAL CONFIGURATION: Refer to the terminal configuration diagram (usually found in the on the inside of the motor terminal cover plate or in a

new motor’s manual) and the motor rating plate to select the correct mode of operation for the motor and VFD combination.

A three-phase motor should be configured to accept 3-electrical-conductors from the VFD output. The rating will usually be described as: 380/415V or 415, or similar.

NOT MORE THAN ONE VACON 100 VFD SHOULD BE INSTALLED IN EACH QUINTEX (EXTERNAL MOUNT) ENCLOSURE It is okay to install Cheetah Data-loggers, Input-Output units, etc. within the same enclosure (with the VFD).

EACH FAN UNIT MOTOR MUST BE CONTROLLED BY ITS OWN DEDICATED VFD (In some cases combined contra-rotating-fan units can have a single VFD installed, to control it).

ENSURE THAT TERMINAL CONNECTIONS ARE CORRECTLY MADE-OFF AND SUFFICIENTLY TIGHT Use (as required) ferrules, rings, spades or similar to make sure that there is reliable connections throughout the whole circuit, in each case. Poor connections will eventually cause issues (if not immediately) with the potential of terminals to

burning-out/failing.

TAKE CARE WHEN SELECTING A LOCATION TO MOUNT THE VFD TO LIMIT ANY VIBRATION

The VFD equipment is constructed from sensitive electronic components with mechanical connections and terminals. Vibration of the installed device should be kept to a minimum.

AVOID INSTALLING VFDs TO DUCTWORK Refer to the Vacon installation manual for the installation of the power connections to the VFD. Remove the power-

terminal cover plate in order to get access to the power connections (see the image of terminals below).

The power input is on the left-hand-side.

INPUT VOLTAGE (3-PHASES) IS CONNECTED TO THE TERMINALS: L1, L2 & L3.

The motor connections are on the left-hand-side.

MOTOR (OUTPUT) VOLTAGE (3-PHASES) IS CONNECTED TO TERMINALS U/T1, V/T2 & W/T3.

BOTH INPUT & OUTPUT CONNECTIONS ALSO REQUIRE EARTH TO BE CONNECTED AS PREVIOUSLY DESCRIBED.

The image below shows a Vacon 100 VFD installed within a Quintex enclosure. Also installed is a Cheetah data-logger unit. When installing the VFD leave enough room at the bottom, for cable entry – and enough room at the top to allow heat venting through the side grilles. The VFD and data-logger units are secured in postion using tech-screws (self-drilling/tapping fasteners) . 20mm electrical stuffing glands are used for the SY-cable entry and a 25mm grommet is used for the network and data-logger aerials to leave the enclosure. An additional network cable can plug into the VFD and then exit the enclosure to connect to the next device (usually a VFD) on the Cheetah network.

Installing the Vacon (OPT-C4-V) LonWork option card: Vacon LonWork (option) cards are boxed separately to Vacon100 units. With the power to the VFD switched-OFF, follow the points listed below to install the card to the Vacon100.

Ensure that the power to the VFD is isolated.

Open the OPT-C4-V packaging box and carefully remove the LonWork card from the anti-static protective sleeve. Avoid touching the terminals of components on the card.

Gently install the LonWork card to SLOT-D within the VFD. Slot-D is the middle position of the extra option slots that are available under the VFD access flap to the main control board and I/O terminals. Take care when plugging the card into the connector on the main PCB.

Slot D shown as the middle slot (image above)

32

Powering Up the VFD: After the VFD has been fully installed to the motor that it will control and the wiring has been checked [WHEN IT IS SAFE TO DO SO], the VFD can be powered-up (switch on the local electrical isolator). ENSURE THAT THE MOTOR AREA IS CLEAR BEFORE SWITCHING, AS THE VFD MAY AUTOMATICALLY START. The Vacon 100 keypad can be used to access running and set-up measurements and parameters. When power is applied, the VFD will begin a start-up sequence – the Vacon logo will appear on the screen. After a while, the set-up wizard will appear. SAY NO TO THE SET-UP WIZARD. Follow the VACON 100 installation/commissioning procedure that is shown on the following page to set-up the key parameters that the VFD needs to operate correctly. Record the values that are set for each motor.

Testing the operation/rotation of the Vacon 100: The Vacon 100 VFD has various modes of operation - the three primary modes are:

Mode of Operation: Conditions of Use: Description of Operation:

I/O Terminal control CHEETAH

OPERATION

In this operating mode, the Vacon 100 VFD will operate from commands that are applied to the input-and-output control

terminals that are located within the VFD (under the access flap – when the main cover has been removed.

IN NORMAL OPERATION – THE VACON 100

MUST BE SET TO I/O TERMINAL.

Keypad control

USED TO TEST THE VFD OPERATION

(MANUALLY STOP & START)

Using the Keypad control, the VFD can be manually started and

stopped in order to check that the VFD has been installed correctly AND TO CHECK THE CORRECT FAN ROTATION.

AFTER TESTING, THE VFD (MODE OF OPERATION) MUST BE RETURNED TO I/O TERMINAL CONTROL.

FieldBus control NOT USED

The VFD will operate ONLY from Bus communications (ModBus,

LonWorks or similar protocol). This type of operation does not allow other functionality that is required for Cheetah to operation

properly, under all condition. DO NOT USE FOR CHEETAH CONTROL.

TO CHANGE THE MODE OF OPERATION TO KEYPAD CONTROL Use the following parameter change sequence (on the VFD keypad):

REMOVE THE WIRE LINK BETWEEN VACON 100 TERMINALS 6 & 8

(otherwise, the parameter cannot be adjusted)

press the FUNCT button

select Local/Remote press (OK)

using the arrow keys, select

Local press (OK)

the Vacon screen should then display the Multi-monitor display

You will then be able to START and STOP the VFD using the GREEN and RED buttons on the keypad.

38


quintex.co.uk

With the ability to stop & start the Vacon 100, the VFD and fan motor operation can be tested. This allows each individual VFD installation to be checked and verified. Make sure that the VACON 100 installation/commissioning procedure has been completed before changing to keypad control and performing the MOTOR RUN TEST. Initially, press the start button just to start the VFD – should start to hear the VFD operation begin – then press stop. This should start the motor and fan turning. With the stop selected (with care) check the MOTOR ROTATION IS CORRECT. The fan should spin the correct way – there is often a DIRECTION OF ROTATION ARROW on the fan unit. Make sure that the fan is spinning the right way.

Inverter design does NOT allow for repeatable rotation sequencing between different units. Many fans may appear to produce ‘extract flow’ when spinning the wrong way.

The fan rotation direction arrow should give the direction that the fan must spin. If on double, run the fan both ways to ascertain the best rate of flow – this will be the correct rotation.

Fan rotation must be verified to be correct in ALL cases.

IF THE FAN ROTATION IS CORRECT: Press the START button again to allow the fan to start properly. The motor (and

fan) will operate at the keypad reference speed.

IF THE ROTATION IS NOT CORRECT: Isolate the power supply to the VFD (the manufacturer recommends that the unit

should be left for at least 5min – for the internal stored power to dissipate). Then remove the electrical power terminal cover and SWAP TWO PHASES (ONLY) on the VFD OUTPUT (or MOTOR) TERMINALS. By swapping just two phases (it doesn’t matter which to), with each other, the three-phase motor will then run in the OPPOSITE DIRECTION. Do NOT attempt to switch two-phases on the INPUT terminals – this will NOT reliably change the motor rotation direction.

press the FUNCT button

select Local/Remote press (OK)

using the arrow keys, select

Remote press (OK)

the Vacon screen should then display the Multi-monitor display

For each Cheetah installation, complete the EQUIPMENT INSTALLATION paperwork (as per the sample on the last page of this manual) in full.

Cheetah Signal Cables: There are two types of cable that are used to connect the Cheetah components and sensor equipment together. The cables come pre-terminated in various lengths. Cables that are being installed should be chosen to be long enough to run between the components that are to be connected. The cables must NOT be excessively long – as any excess length will have to be neatly coiled. Excessive cable lengths can cause issues with the operation of the Cheetah system. Likewise, cables must not be too short, so that they will NOT need to be connected together a cable joiner. Ensure that cables installed away from power cables (150mm separation) and install all cables so that they CANNOT be damaged by heat, sharp edges, crushing, being pulled, etc. Cables are never cut and remade. The cables are factory produced to a very high standard and will ensure the correct operation of the Cheetah system.

The shrouds protect the connectors from damage and displacement and make the Cheetah system very reliable. To remove a Neutik shroud, unscrew the back plastic cable sleeve from the metal barrel. Gently pull-out the connector from the barrel and unclip the remaining (secondary) cable sleeve. Shrouds can be removed to get cables through small cavities (etc.) but always replace the shrouds before connecting the cables to a device.

NETWORK CABLE - SIZES AVAILABLE:

0.5m 1m 2m 3m 5m

10m 20m 30m 40m 60m

CHEETAH EQUIPMENT INSTALLATION

SITE:

Date of install:

Installing engineers:

Cheetah sensor equipment installed:

SENSOR-PROCESSOR (1) OPT1 OPT2 T1 T2 T3 T4




Vacon 100 VFD key parameter set-up:

VFD: EXTRACT (1) SUPPLY EXTRACT (2) EXTRACT (3) EXTRACT (4)

Restore Factor Default

Currnt Limit

Motor Nom. Crrnt

ROTATION CHECKED

* Motor Current

* With the Vacon 100 VFD set to keypad and the motor running (with the correct rotation) – viewing the Multimonitor screen, increase the frequency

to 50.00Hz and record the running current from the box labelled Motor Current.

Each Cheetah system component is boxed with an extra (separate) adhesive label. Stick the labels to the reverse side of this installation sheet to be included in the installation/reference documentation. Produce a rough plan view layout of the kitchen showing the canopy/s and the installed sensors (and sensor-processor/s) equipment, so that the commissioning engineer knows how to configure the system. Label each sensor (and sensor-proc.) accordingly – eg. S/P1, OPT1, T1, T2, etc. For more complex ventilation systems, detail the relationship/s between canopy/s and (multiple) extract fans. Cheetah system installed and components tested as per Cheetah Equipment Installation Manual:
