Many protection and control systems are used in industry. Often applications requirevarious items of equipment to supervise correct operation.

Aware of this, FANOX has focused the design of a significant part of their products onspecific applications, equipping them with complementary functions which offer acomplete protection and control solution in a single unit.

All of this is the result of the investigation into the market requirements for specificapplications and use of internal skills and knowledge to develop a practical andeconomic solution.

Our wide experience in communication, digitalisation, protection and control materialshas allowed us to create an extensive range of applications ranging from a simplevoltage control relay, through a complete range of electronic protection for motors, tosophisticated cell protection and control systems for electric substations.

This section details some of the characteristic applications of our products involving theintegration of various functions in a single unit.

These applications are:

• Motor protection

• Pump protection

• Generator protection

• Elevator protection

• Medium voltage protection

• Customized electronic products

This catalogue features the characteristics of the units listed in this section.

Applications

The electric motor is, perhaps the most important operating device in industry.

High cost production and valuable machinery can become completely paralysed due toa fault in a single motor. The cost of a motor rewind or replacement is insignificantwhen compared to production downtime.

Experience shows us that motor protection continues to be a problem, based on thehigh number of breakdowns occurring on a daily basis, mainly caused by: overloads,locked rotor, phase imbalance or phase loss, long and heavy start-ups, excessiveoperational cycles, or heating from non-electric causes.

Over 60% of faults are due to causes not adequately detected by conventionalprotection systems. These produce excessive heat in the windings, which causes adrastic reduction in the operating life of the motor.

FANOX offers the ideal solution with its wide range of electronic protection relayswhich, worldwide, prevent motors from burning out on a daily basis, with thesubsequent savings made on repairs and the resultant downtime

The technical advantages that illustrate the benefits of FANOX relays as follows:

• Thermal memory which continuously memorises heating and cooling during start-up, operation, overload and shutdown cycles.

• The immediate detection of missing phases, even with the motor operating with asmall load, shutting it down quickly to prevent costly faults.

• Identification of the cause of the trip. The relays instantly signal the cause of the trip,permitting the rapid identification of the fault, and therefore rapid actions to betaken.

FANOX relays can also fitted with an external OD display module, the size of a 22mmdiameter button, which, mounted on the exterior of the motor control cabinet orcentral unit, displays the cause of the motor stoppage. The display module alsoincorporates a reset button for operator convenience.

All of the above features, together with the connection of the relay to heat sensors(PTC’s) fitted in the motor to provide protection against overheating, the differentclasses of trip to adapt the protection against overloads for all class of applications andthe incorporation of protection against phase reversal, have made FANOX relays intothe most reliable on the market, far exceeding the limited functions of otherconventional methods of protection such as thermal relays, electro-thermal relays ormotor protection relays.

All in all, FANOX motor protection relays provide significant advantages at a verycompetitive price, significantly reducing downtime by prolonging the operating life ofthe motor and reducing maintenance and rewinding costs.

Motor protection

One of the most important problems for pumps during operation is the efficientdetection of, and protection against dry running.

The most commonly used detection system is the use of float switches and levelprobes, although the reliability of these methods is rather limited given the operationfaults that occur as a result of sludge and particle deposits on the electrodes, low waterconductivity, etc...

Keeping the motor running in excessive overload conditions is equally important. Thisis normally carried out using thermal bi-metallic relays, although these are not alwayseffective.

Other faults that usually occur are those related to the phase loss or phase sequencereversal in the case of three-phase pumps or voltage increases in single-phase pumps.

Just one of these occurrences could cause elevated losses, leaving the pumps out ofservice.

FANOX electronic relays are specifically designed for the complete protection of bothsingle-phase and three-phase pumps, or of any other system where no load operationis critical.

The great advantage of these relays is that by using the motor itself as a sensor,without the need for external detectors, they control the motor load and stop themotor before a costly fault occurs due to dry running, cavitation, closed valve, etc.

In this way awkward float switches and level probes are not required, therefore savingboth time and money on installation and maintenance.

The underload is controlled by the measurement of undercurrent or of cos ϕ for three-phase pumps or of just undercurrent for single-phase pumps.

The relays memorise the thermal image of the motor during its heating and coolingcycles thereby offering effective protection against overloads.

Other aspects worth pointing out are the protection against phase imbalance andphase failure and the detection of the phase sequence to ensure that the motor rotatesin the right direction.

FANOX relays also provide protection against overvoltage in single-phase pumps.

The three-phase relays can also be fitted with the OD display module previouslydescribed.

Pump protection

7

One of the main problems when it comes to protecting a generator is protectionagainst overloads. The use of thermal-magnetic switches, fuses or thermal relays is noteffective, as their trip curves do not adapt to the operating limit curve or generatordamage curve; this curve relates the generator overload to the maximum time that canbe allowed for its operation in these conditions with no significant damage.

FANOX offers three devices to maintain the generator within the established operatingparameters.

The GEN relay provides effective protection against overloads and imbalance or amissing phase, signalling the cause of the trip. It is equipped with a thermal memorywhich memorizes the generator heating and cooling in such a way that it will tripfaster if another overload has been detected previously. Its 16 selectable trip curves,situated below the generator limit curve, allow for optimal operation withoutoverloads causing irreparable damage.

The H relay controls the frequency, ensuring it is kept within the previously set limits.It has 2 independent output relays and the minimum or maximum frequency outputrelay is activated according to the cases selected with the delay.

The U3 relays are used to control the voltage value of the installation.

Lift protection

Generator protection

A fundamental aspect for the safety and correct operation of an elevator is to ensurethat the electrical installation is protected against problems caused by phaseasymmetries or a missing phase or reversal of the phase sequence, and to ensure thatthe motor operates within the established load limits. Also the air temperature of themachine room or of the control panel must be kept within the limits established by theEU Directive for Lifts, to guarantee the correct operations of the items installed there.

FANOX has relays specifically developed to cover these requirements.

The T2 relay monitors the air temperature in the machine room or the control panel,according to standard EN81-1. Two potentiometers allow the temperature limits to beadjusted to between minimum limits of –5º to +5º and maximum limits of +40º to 55º.The T2 is suitable for installation in lifts with and without a machine room.

The S phase control relay protects against asymmetries, missing phases and phasesequence inversion.

ST and GL relays are available for motor protection. The first of these detectsasymmetries, phase loss and phase sequence reversal and motor overtemperature bymeans of PTC sensors. The GL relay is a current relay which is equipped for protectionagainst overload with thermal memory, blocked rotor, asymmetry and phase loss,incorrect phase sequence and overtemperature by means of PTC sensors.

The energy sector, particularly electrical energy, is undergoing a profound worldwidetransformation.

The rapid advance of modern society and its increasingly high demand for energy,means there are more and more distribution lines and installations requiring advancedsupervision systems to keep them operating in a safe and continuous manner.

Aware of this, FANOX, following years of research and development, offers a completefamily of equipment that provides an efficient and economical solution.

The SI system consists of a series of digital and communicated protection and controlrelays for electrical distribution installations and networks intended for industrialsystems and medium voltage electrical substations.

The family consists of equipment specifically designed to protect and control, amongstothers, the following items:

• The medium voltage lines which distribute electrical energy to installations.• The transformers which adjust the levels of medium to low voltage.• The machines and motors, consuming electrical energy, of each industrial

installation.• The generators, in the multiple cases where the plant has cogeneration.

All the units are digital and communicated, providing them with a number ofadvantages:

• Self-diagnostic and event recording functions into a non volatile memory.• One or two communication ports using the ModBus-RTU protocol.• A communication port is fitted with a GSM modem (AT-commands), which can send

SMS messages to the mobile phones of maintenance staff.• They have an alarm recorder which can be configured by the user, to be used in built

in systems.• Two oscillographic recorders are fitted in the non-volatile memory, capable of

recording up to 8 analogue and 32 digital waves, sampled 32 times/cycle during 33cycles.

• A powerful programmable logic, to configure the outputs, the commands and theequipment alarms.

From an operating safety viewpoint, it is worth mentioning the internal backupbatteries which provide the energy required to maintain the unit in operation, plus thecapacity to act on cut off items (trip coil), should the auxiliary supply fail.

They are fitted with an MMI consisting of an LCD display and keys. Via this, systemmeasurements, instantaneous states, counters, status of the inputs and outputs, dateand time, event recorder, etc. can be consulted.

Another way of connecting with the unit is to use its Sicom communicationsprogramme, which allows the information to be adjusted, configured and visualised.

Mode of Operation

a) Change from on line direct start to soft start:

1) Cut off the cable from the motor and insert theES starter.

2) Connect the control input to two of the inputlines. Set the potentiometers according to thesettings mode.

3) Reconnect the power supply.

On connecting C1, the starter performs a soft motorstart. On disconnecting C1, the motor stops, thestarter resets to zero and after 0.5 seconds a newsoft start up may be performed. (fig. 1 andfig. 4)

b) Soft Start / Soft Stop (fig. 2 and fig. 3)

When S1 is closed (connection diagram), the softmotor start is realised according to thepotentiometers setting of initial t and % torque.

When S1 is open the soft stop is realised inaccordance with the ramp down potentiometersetting.

• For three-phase induction motors of up to 22 kW / 400 V.

• Built in heat dissipater and electro-mechanical bypass relay.

• Substitutes the conventional contactors with a greater operating life. One indirect start-up and three in star-delta start-up.

Operation

These units represent the best protection againstthe premature ageing of motors and mechanicalitems.

Sudden starts and stops, that can produce damagesin the bearings and gears of the motors, areeliminated.

They prevent frequent faults and objects fallingonto conveyer belts.

They reduce mechanical impact in motors, axles,gears and belts, significantly prolonging theoperating life of the controlled units.

An electronic circuit with semiconductors starts themotor without using the contacts. Hence these donot withstand sparks or erosion.

When the minimal voltage of the motor is reachedthe semiconductors are bypassed by the relaycontacts. Thanks to this technology, the ES startershave a longer operating life than conventionalcontactors.

They are easy to install and control. They canoperate by means of an external control signal, suchas a programmable automaton.

ApplicationsFor three-phase motors in applications such as:

• Pumps.

• Cold compressors.

• Conveyor belts, lifting devices, etc.

• Mixers.

• Fans, extractor fans and blowers.

• Garage doors and elevators.

• Concrete mixers.

• Palletizer devices, etc.

SIA

ApplicationsThe SIA protection is specifically designed for theprotection of transformation centres, associated to amixed cut off item, via breaker or fuse.

The transformation centre has a medium voltageinput line, a transformer of, for example, 500kVAor 1MVA of nominal power and various lowvoltage lines.

ProtectionThe centre protection possesses two cut-off items:

• Breaker: these centres have a breaker in themedium voltage part with a limited cut-offcapacity. This permits the elimination of thegreatest amount of incidents, particularly thoserelated with the neutral. The breaker must alwaysbe closed manually.

• Fuse: when the leakage current is extremely high,the breaker does not have sufficient cut-offcapacity, discharging this responsibility on thefuses. The protection is blocked, when there ismore than 300 A of leakage current.

SupplyAs well as functions of the secondary cell protectionanother important characteristic of thesetransformation centres is the need to eliminate theirmaintenance. A way in which this maintenance canbe reduced is to have the electronics self fed from theoperation current itself. This avoids the use of batteries,chargers, etc.

It also admits another two types of supply:

• Auxiliary voltage at 230 Vac.

• Via communications port RS232 using a 9V battery.This permits the SIA to be powered and set whensetting in operation or to check operation under anycircumstance.

Equipment SettingsThe SIA unit stores the settings in a removable andinterchangeable non-volatile memory card. Thisallows for a faulty unit to be replaced by anotherwithout having to reset the unit via HMI or via theSIcom communications software.

Applications ProtectionThe SIL unit is specifically designed to protect mediumvoltage lines in the following applications:

• Transformation centre and basic line for solid neutral.• Basic line for isolated neutral.• Non integrated line with SCADA for solid neutral. • Non integrated line with SCADA for isolated neutral.• Integrated line with SCADA for solid neutral.• Integrated line with SCADA for isolated neutral.

The protection functions of the SIL unit are those ofthe line itself, one instantaneous time phase andneutral current, both with 2 levels, and one inversetime phase and inverse time neutral with selectableinverse, very inverse and extremely inverse timecurves, according to the IEC standard.

It is also fitted with a PT 100 input to measure themachine temperature.

CommunicationThe SIL unit has front communication so that thestatus of the unit can be consulted and its operatingparameters can be changed via the SIcomcommunication software.

According to the model, it has a rear port for remotecommunications with protocol ModBus-RTU,specifically intended for the integration of the unit inSCADA systems. According to the model, it also hasthe possibility of SMS communication, on a list ofpreset telephones for the maintenance staff when itis not connected to a SCADA.

Control and MeasuringThe SIL unit is fitted with a powerful input andoutput configuration mechanism via programmablelogic.

It has 5 outputs: 3 NA and 2 NC which can beconfigured individually.

It has 4 inputs which can be used as analogue ordigital. These inputs are galvanically isolated fromthe CPU to eliminate EMC problems.

It is fitted with the following measures: Phase andneutral currents, voltages and power (according tothe model), temperature of the machine andanalogue inputs.

SupplyThe SIL unit has 8 NiMH Technology AA sizebatteries providing the required power should therebe a loss of auxiliary power. As well as feeding theunit, it provides the voltage for the breaker trip, theinputs power and, according to the models, thepower for the external modem for SMS messages.

Relay with adjustable delay timeand sensitivity / Multirange relay

Multirange relay. 22,5 mm wide Toroidal transformers

• To be used with CT-1 transformers.• Modular size. DIN rail mounting .• Sealable front cover.

• Very high level of inmunity.• 22,5 mm wide. Saving space in the distribution

board.• DIN rail mounting.• To be used with CT-1 transformers.• Suitable for Motor Control Centres (MCC) and

electrical distribution board in general.

• To be used with ELR-B, ELR-3C and D30 relays.• The transformer and relay assembly sensitivity is

fixed by the relay.

Working principles: The toroidal transformer isinstalled between the source and the load. Thesystem works on the current balance principle. Ina correct installation the vector sum of thecurrents is zero and the relay will not trip.

In case of an insulation fault on the circuit aleakage current flows to earth. Now the vectorsum of the current passing through thetransformer is not zero, this inbalance isdetected by the transformer, which induces acurrent in the secondary winding which isconnected to the relay.

If the fault level is higher than the selectedsensitivity, and when the trip time delay haselapsed, the relay trips and actuates on the shunttrip of a circuit breaker or the coil of a contactorinterrupting the supply to the load.

The dimensioning of the toroidal transformerdepends on the diameter of all active wires (notearth conductors) put through thetransformers.

The motor protection

The electric motor is one of the most importantoperating devices in industry. Many times theshutdown of an industrial process is caused bya simple motor. High-cost production runs andvaluable machinery can become paralysed atgreat cost, even more than the cost ofrewinding the motor.

Experience shows that motor protectioncontinues to be a problem, based on thenumber of breakdowns occuring every day.

Over 60% of failures are caused by overheatingof the motor windings. These can be detected,and prevented, by measuring and analysing thecurrent being absorbed by the motor, or bycontrolling temperature limits of the winding.The major causes are as follows:

• Overloads

• Locked rotor

• Over and unde rvoltage

• Phase inbalance or phase loss

• Long and heavy start-ups

• Excessive operating cycling

• Heating from non-electric causes

• Inadequate motor ventilation

• High room temperature

• Insulation failure

The following diagram shows the dramaticdecrease suffered in the electric life of a motordue to the excessive heat of the motor windings(Montsinger’s rule).

As one can see, a 10ºC increase in temperaturereduces the useful life of the motor by half.

The most reliable protection options in commonuse are:

• Fuses or circuit breakers for short-circuitprotection.

• Electronic motor protection relays withthermal memory.

• Contactors for motor control.

FANOX relays

Our R+D Division has allowed FANOX todevelop a wide range of easy-to-install andoperate electronic relays, at truly competitiveprices, which will save downtime and money.

FANOX motor protection relays work with thecurrent measured in real time. The current,which is read by three current transformers builtinto the relays, is electronically processed andused as a model of the thermal image of themotor, and to compare it with the values set onthe relay.

The three power supply cables to the motor arenot directly connected to the relay, but passthrough its corresponding holes.

This provides motor protection against:

• Overloads: since the relay creates a model ofthe thermal image of the motor during itsheating and cooling cycles. In this way, inoverload conditions, the relay will take intoconsideration previous operating conditionsof the motor, and will trip faster if the relayhas detected other previous overloads. Thisthermal memory is independent of theauxiliary voltage supply of the relay so that itis stored even when this voltage is cut off ordisconnected. The different tripping curvesavailable for selection in the relays allow forprecise adjustment to any kind of motor start-up or work cycle.

• Phase inbalance and phase loss: even if themotor is running below its full load current.

• Incorrect phase sequence detection is highlyimportant when the correct phase sequence iscritical as in compressors, pumps, fans andother applications (GL, P, PF).

• Underload by undercurrent: protects themotor against working without load, veryimportant in pumps (P and PS).

• Protection against no-load operation: underloadprotection by cos ϕ has been incorporated sothat the relay differentiates precisely betweenvery low load and no-load operations, anddrops out in the latter case (PF).

In addition, when the relay is connected tothermistor sensors (PTC), it protects the motoragainst electrical and non-electrical overheating(GL, G and BG).

A visual display of the tripping reason allowsmaintenance personnel to identify andimmediately act on the underlying causes. Theuse of the OD display makes this operation mucheasier.

All of this make FANOX relays the idealprotection for your motors (pumps, compressors,fans, etc).

1. Installation

1.1. General

For correct installation and operation of therelays, please bear in mind the followingconsiderations:

After being fixed to theDIN rail, the cables for thethree phases should bepassed through the holesin the relay.

The maximum section of 700V insulatedwires that can pass through the holes are:

Assembly attached to other components: it isrecommended to separate the relays of otherunits or items that could cause strongmagnetic fields, such as power or controltransformers, contactors, frequency variatorsor high current busbars.

In star-delta starting,the relay or thecurrent transformersmust be installedbetween the fuses orcircuit breaker andthe contactor.

Relays used in combination with frequencyinverters:

a) Not to be used with frequency inverters: - GL relays if the protection against phase

sequence selector is in the "ON" position.- P and PF relays.

b) The following can be used with frequencyinverters:- GL relays if the protection against phase

sequence selector is in the "OFF" position.- C, G and BG relays.

Never connect the relay or currenttransformers of the auxiliary power supply tothe inverter output.

Connection between the PTC sensors andthe relay (GL, G and BG). For PTC connectionlengths over 100 m or when the influence ofhigh frequency transient voltages isexpected, it is adviseable to use screenedcable and connect the screen to terminal T1.

Note: every relay comes with an instructionmanual providing information on its correctinstallation and setup.

b) If the value of the IB of the motor withoutload is unknown:

• If the pump is adequately dimensioned,the recommended value for this factor is0,7. Adjust the potentiometer"undercurrent" at 0,7.

• If the pump is excessively dimmensioned,and during this functioning unwantedtrips should occur, the underloadadjusted factor should be reduced to 0,6approximately.

2.4 Undercurrent.

Single phase relay PS

The setting of the underload trip level is madeusing a potentiometer in wich a factor between0,4 and 0,9 is to be chosen. By multiplaying thisfactor by the adjusted IB , we obtain a currentvalue under wich the relay will trip and dis-connect the motor. The trip is delayed 5seconds.

a) If the value of the IB of the motor withoutload is known:

• To avoid unwanted trips it isrecommended to adjust the value 15%above the IB of the motor without load.

Example:

b) A slightly oversized motor for its application.The cos ϕ of the motor is 0,25 whenworking without load.

If the above mentioned cos ϕ values areunknown, the underload trip setting can bemade in the following way:

1. Set the underload trip delay to zero by movingthe three dipswitches to the left (trip delay).

2. Using the potentiometer (cos ϕ setting), setthe cos ϕ value to the minimum 0,15.

3. Start up the motor and run it with theminimum estimated load.

4. Slowly turn the cos ϕ potentiometerclockwise until the relay trips and the cos ϕLED lights up.

5. Turn the cos ϕ potentiometer anticlockwiseuntil the cos ϕ is set at approximately 30%less than the previous value (point 4).

6. Set the underload trip delay using the 3corresponding dip switches.

2.3 Underload by cos ϕ. PF

The cos ϕ underload trip level is set by means ofa potentiometer from 0,15 to 1,0.

Select this value taking into consideration theno-load motor cos ϕ and that corresponding tothe estimated minimum operating load. Choosean intermediate value between these two cos ϕlevels and set it in the relay.

Select the underload trip delay from 5 to 45seconds and set it with the 3 correspondingdipswitches (trip delay).

For your guidance you can find below twopractical examples.

a) A very oversized motor for its application.The cos ϕ of the motor is 0,15 when workingwithout load.

PS relayThis adjustment is to be made according to thenominal current of the motor IN indicated in itscharacteristics plate. The value to be set IB is thesame as IN. The relay trips with overloads above1,1 x IB

2.2 Current setting IB.

Relays C, GL, P, PF, G, BG y GENAdjust the current IB on the correspondingdipswitches (full load current). When settingthe current take into account that the basecurrent of the relay always remain added to thecurrent selected with the dipswitches in “ON”position (to the right). The total addition is theset current IB.Overload tripping current from 1,1 x IB.

a) For motor or generator rated currents (IN)within the range of the relay, the setting IB

must be equal to the IN of the motor orgenerator.

IB = IN

b) For motor rated currents below the range ofthe relay, the setting IB must be equal to therated current of the motor IN multiplied bythe number of times that the conductorshave been passed through the relay holes.

c) For motor or generator rated currents (IN)above the range of the relay, use threecurrent transformers .../5 in combinationwith the C9, GL16, P19, PF16, G17, BG17 orGEN10 according to application.

C9, G17 and BG17: Its recommended alwaysto pass the conductors two times or morethrough the holes in the relay.

Monitoring the current. GL and PAn incorrect phase sequence is detected bycurrent sensing and it is only operative duringthe motor start-up, for correct detection thestarting time must be longer than 0.2 s.

In GL relays the user can activate or desactivatethis protection by a dipswitch. Should the rightphase sequence be critical, move the dipswitchto the “ON” position. If this protection is notrequired leave it always in the “OFF” position.

Monitoring the voltage. PFAn incorrect phase sequence is detected byvoltage monitoring.

In the event that an incorrect phase sequencehas been detected, the motor will not start-upsince the relay is tripped because it haspreviously detected the wrong phase sequence.

2.6 Reset.

Manual reset

Push the “RESET” button.

After tripping due to phase imbalance, phaseloss, undercurrent or incorrect phase sequence,the relay could be reset after 2 seconds haveelapsed.

When a trip is caused by an overload, thewaiting time could be as much as 8 minutes forC, GL, G and GB relays, 5 minutes in P and PFrelays, and 1 minute in GEN relays, dependingon the severity of the fault.

Remote reset

After the required waiting time, disconnect therelay’s auxiliary power supply and thenreconnect it after 3 seconds.

In P and PF relays the reset position dipswitchshould be set at “man”.

Automatic reset

Only available in PS, P and PF relays.

In the P and PF relays choose this mode bymoving the dipswitch to the “auto” position.

After any kind of trip, resetting will take place,continuously for unlimited starts:

• P and PF relays: 15 minutes approximately

• PS relay: 4 minutes approximately

3. Operating test. C, GL, P, PF, G, BG and GEN.

To perform the trip test for phase loss, thecurrent which passes through the relay must behigher than 0.7 the set current IB. Under theseconditions, push and hold the TEST button forthree seconds, the relay will trip due to phaseloss and the corresponding LED will light up.
