Product description

Microprocessor controlled system for regulation and monitoring of the constant room pressure maintenance. It has to be maintained a constant over- or underpressure in clean rooms or laboratories compared to adjoining rooms (e. g. corridor). This avoids the intrusion respectively loosing of contaminated or uncleaned air with an excessive dust content depending on the application.

The room pressure controller iCM-RP regulates independently the necessary free programmable room under- or overpressure. The setpoint setting occurs via the digital inputs (parameterization via password protected internal menu or laptop with PC2500 software (USB fl ash drive)).

The adjusted room pressure actual value is shown on the full graphic LC display as a numerical value in Pascal. Exceeding or undercut of the adjusted setpoint setting triggers the visual (red LED) and optional acoustical alarm.

The room pressure controller iCM-RP is a suitable system supplement for the fume hood controller iCM-F-0 (regulation to a constant air infl ow) to guarantee the constant room pressure maintenance of the laboratory. Together with the duct pressure controller iCM-DP which regulates a bypass damper or the frequency converter of the fan directly SCHNEIDER provides a completely integrated and independent regulation system.

Functional description

Microprocessor controlled fast regulation system for a constant pressure maintenance of rooms. A fast control algorithm compares the room pressure setpoint with the measured room pressure of the static differential pressure sensor and controls fastly, precisely and steadily independent of pressure fl uctuations within the duct net.The parameterized constant room under- or overpressure is therefore constantly maintained.

The room pressure to be regulated is freely adjustable and can be stored fail-safe in an EEPROM. The control velocity is very fast (control time < 3 s) and the actuator running time for 90 ° can be freely adjusted within a range of 3 s to 24 s.

Due to the high control velocity the installation of a door respectively window contact is mandatory, to achieve a steady control behaviour and to avoid unnecessary control cycles during the opening and closing of doors or windows.While using the door or window contact the current control value is „frozen“, this means the room pressure regulation is inactive. The contact can be parameterized as NO (normally open or NC (normally closed).

The SCHNEIDER dampers for the room pressure controller iCM-RP are available in round or rectangular versions.

The room pressure controller iCM-RP regulates independently and has an internal limit value monitoring with a potential-free relay output each for the the upper and lower limit value.

Parameterization

The parameterization of the setpoints and the readout of the actual value occur via laptop and software PC2500 (USB fl ash drive) or the integrated menu.

Constant room regulation

The room pressure controller iCM-RP is delivered in a wall housing, already contains the static differential pressure transmitter (± 50 Pa) and is suitable for the independent room pressure control of supply air as well as for exhaust air.

In block diagram 1 the room pressure controller iCM-RP follows the variable respectively constant room exhaust air and maintains the room pressure within the laboratory rooms in a constant underpressure (e. g. -10 Pa) via the room supply air although the exhaust air volume fl ow is re-gulated variably via the temperature sensor T.

The room pressure controller iCM-RP can control rooms in under- or overpressure by a suitably connected static dif-ferential pressure transmitter. Laboratories are controlled in underpressure while clean rooms are controlled in over-

pressure to avoid the intrusion of „unclean“ air into the clean room.

When used in laboratories (underpressure) the static dif-ferential pressure transmitter of the iCM-RP measures the pressure difference between the corridor (+) and the clean room (+) und generates the actual value signal for the to be adjusted setpoint.

When used in clean rooms (overpressure) the pressure difference between corridor (-) and the clean room (+) is measured. In this case the (-) connection of the differential pressure transmitter is led through the corridor.

The volume fl ow for the room exhaust air can also be con-veyed in a two-stage operation (day/night operation) or via a constant volume fl ow controller (CAV).

Due to the fast and precise control algorithm and the fast running actuator with „Fast Direct Drive“ activation it is pos-sible to adjust relatively airtight rooms smoothly as well. For extremly airtight rooms we recommend SCHNEIDER‘s VCP500 which is especially developed for this application.(see technical data sheet VCP500).

Graph 1: constant room pressure regulation (iCM-RP)Constant room pressureThe constant room pressure is regulated depending on the digital input circuit.

The available operating modes are shown in graph 1 and table 1. A 1-point, 2-point or 3-point operation (set value 1 to 3) can be easily realized by direct activation of the digital inputs or via the button Vmax.

Setpoints 1 to 3 for room pressure specifi cation

The room pressure setpoints shown in graph 1 are parame-terized for example with the following setpoints:

setpoint 1 (normal value) = + 40 Pascal setpoint 2 (reduced value) = + 20 Pascal setpoint 3 (emergency) = + 10 Pascal

The room pressure actual value signal (A-Out1) correlates with the adjusted room pressure.

For the circuit of the digital inputs refer to table 1 and termi-nal connection plan on page 11.

Positive or negative room pressure setpoint values can be regulated for the airlock pressure controller or clean rooms.

Alarm thresholds

Two independent alarm thresholds can be parameterized with arbitrary alarm values within the sensor range. The alarm threshold values high and low affect the alarm relay. If the alarm relay sinks, the alarm threshold is exceeded or undercut and the alarm status will be signaled.

The alarm threshold values always relate to the to be adju-sted prevailing room pressure setpoint.

Example: alarm threshold value high = 5 Pascal alarm threshold value low = 3 Pascal setpoint 1 (day) = + 20 Pascal setpoint 2 (night) = - 15 Pascal

During room pressure maintenance setpoint 1 (+20 Pas-cal) the alarm threshold value high will be exceeded and signaled at > +25 Pascal and the alarm threshold value low will fall below and signaled at < +17 Pascal (alarm relay drops down).

During room pressure maintenance setpoint 2 (-15 Pas-cal) the alarm threshold value high will be exceeded and signaled at < -10 Pascal and the alarm threshold value low will fall below and signaled at (alarm relay drops down).

If the input 2 is not wired (dead) setpoint 1 will be automa-tically adjusted.

The emergency (setpoint 3) can only be activated via button Vmax. The reduced value (setpoint 2) can be activated via the button „set“ or the digital input In2.

The contacts can be parameterized as NO (normally open) or NC (normally closed).

Alarm delay timeThe alarm delay time is freely programmable within a range of 0 to 240 s. The alarm mode has to be queued for at least the adjusted time to trigger the alarm. This time period re-duces the triggering of false alarms, e. g. in case of instable air supply.

Door-/window contactTo avoid unnecessary regulation cycles by opening or closing of doors respectively windows and due to the high control velocity (< 3 s) a suitable contact has to be connected which „freezes“ the present control value for the operation time which means that for this time period the room pressure control is inactive. The contact can be parameterized to NO (normally open) or NC (normally closed).



Damper with fast running actuator with feedback potentiometer (standard version)

The room pressure to be adjusted occurs via the damper (supply or exhaust air). The very fast running actuator (3 s for 90 °), specifi cally developed for SCHNEIDER, is directly mounted to the axis of the damper and possesses a torque of 3 Nm and is suitable for round or rectangular dampers up to a diameter of 280 mm or 250 x 250 mm.The actuator is directly activated by the control electronics. (fast direct drive). This guarantees a fast and stable control behaviour.This activation mode shows signifi cant advantages compared to the analogue actuator activation (0 to 10 V DC) because the internal control electronics of the analogue (steady) controlled actuator posssesses a hysteresis which could cause vibrations in the controller in case of narrow room pressures to be adjusted or airtight rooms. A feedback potentiometer signals the actual value of the present damper position to the control electronics. A special control algorithm provides the necessary room pressure without vibration fastly and directly.

During the activation of the actuator the actual damper adjustment (damper control) is tested at the same time. This control concept with integrated monitoring function of the actuator exceeds the high safety regulations which are mandatory for room pressure controllers.

The end position of the dampers (damper close = 0 % and damper open = 100 %) can be arbitrarily parameterized, that means the actuator stops automatically at the pro-grammed damper position and regulates just within the parameterized spectrum (e. g. between 10 to 80 %). Therefore the minimum and maximum volume fl ows can be limited without further effort.

Performance features damper

IMPORTANT!Actuator NMQ12 (3 Nm) can be used for round dam-pers up to a diameter of 280 mm or rectangular dam-pers up to 250 x 250 mm.For larger dampers the actuator NMQ24 (8 Nm) with additional external transformer (additional box E4) has to be used.



Performance features software

Upward and downward control time freely parameterizableThe upward control time (damper open) and the downward control time (damper closed) is freely parameterizable in 1-second steps from 2 to 24 s. For this reason the control behaviour of the room pressure controller iCM-RP can be adjusted optimally to the room conditions (room size and tightness). Vibration tendencies can be minimized or completly avoided by optimal parameterization.

Control parameters

All project specifi c control parameters, e. g. room pressure setpoint, deadzone and close-up range can be retrieved, changed and monitored smoothly on site via the internal service level or a laptop (see overview internal menu list on page 10). A cyclic sequential retrieving and testing of control actual values and setpoints guarantees a very fast, stable and adequate room pressure regulation.

Test- and diagnosis functions

For the commisssioning, diagnosis and simple error search it is very important to have an extensive and exact overview of all measured actual values.

SCHNEIDER‘s special test and diagnosis programm via service module SVM100 or PC software PC2500 provides the service and commissioning staff with the following actual values.

The controller iCM-RP possesses additionally an integrated service level which is accessible with the functional keys via password.

The room pressure controller iCM-RP follows the room sup-ply air and maintains the constant room pressure via the room exhaust air. (e. g. -10 Pa).

Clean rooms are mainly controlled in overpressure to avvo-id the intrusion of „uncleaned“ air into the clean room.

Table 2: example values and reference measurement

Room scheme 2 shows an appli-cation with constant volume fl ow controllers (CAV) each for the room exhaust air of the different rooms.

The room pressure controller iCM-RP regulates automatically the parameterizable room over-pressure (+) independently for each room.

Table 2 shows the paramete-rized values and the reference measurement of the static diffe-rential pressure transmitter. All room pressure controllers iCM-RP are summarized on the (-) = underpressure page and measu-re against a common reference point. This preferred measuring type guarantees the best stabi-lity, at which the reference point should be situated at a construc-tional favorable position (e. g. calm cellar room without wind load respectively air pressure changes (Attention: elevators)). The wrong measurement of rooms against each other (e. g. room 1 against airlock) leads to reinforced vibrati-on tendencies in the room pressu-

re controlling because room pressure changes e. g. in the airlock affect room 1.

Arbitrary reference measurements and iCM-RP confi gura-tions (room supply air or exhaust air) are possible, depen-ding on the applications, at wich the control stability (low vibration tendency) should always be taken into conside-ration.

Block diagram 2: complete independent laboratory control system with laboratory control system iCM-F-0 (face velocity), room pressure controller iCM-RP and duct pressure controller iCM-DP with bleed damper activation

The block diagram 2 shows a complete independent labo-ratory control system. The fume hoods are adjusted to a constant infl ow velocity via the face velocity controller iCM-F-0. Depending on the total exhaust air volume fl ow, which consists of the extracting fume hoods and the constant con-troller CAV, the supply air is compensated in such a way to maintain a constant underpressure of - 10 Pa.

The disadvantage is the direct infl uence of opened doors respectively windows on the room pressure. To avoid un-necessary regulation of the falling room pressure the con-nection of a door and/or window contact is recommended. Therefore the room pressure controller will be „frozen“ with the present damper position (inactive) when a door or win-

dow is open to reduce the wearout of the actuator and the gear signifi cantly.

In this example the duct pressure controller iCM-DP works independently as well and is chosen as a bleed damper ac-tivation. A duct pressure controller via frequency converter FU for the total supply air and exhaust air is also possible.

Further applications (block diagrams): see technical data sheet iCM-LabSystem.

The adjoining table shows the volume fl ows within the ap-propriate duct fl ow velocities and nominal widths. In the laboratory (exhaust and supply air) the duct fl ow velocity v = 6 m/s should not be exceeded due to the acoustic noise (fl ow noise). In case of exceeding this value the sound pressure level of < 52 dB(A) demanded by DIN1946, part 7, can only be achieved with extensive sound absorption. The duct fl ow velocity can fell below v = 0,5 m/s because the room pressure will be adjusted and therefore the re-quired fl ow velocity (volume fl ow) is set.

Tender specifi cation iCM-RPRoom pressure controller with integrated microprocessor, static differential pressure transmitter and fully graphic dis-play with numerical signaling of the room pressure actual value. Fast, constant and automatic controlling (< 3 sec) of room under- or overpressure with integrated monitoring function and acoustical alarm as well as provision of two freely programmable relay contacts (e. g. for exceeding the upper and undercut the lower limit value). All setpoints are freely parameterizable via a password secured internal servicing level or laptop with software PC2500 (USB fl ash

drive). Storage of all system data in the fail-safe EEPROM. Suitable for room pressure regulation via room supply air or exhaust air. Controller built-in a compact and shapely wall housing. Direct digital activation of the fast running actuator (< 3 s for 90 °) for exact and vibration-free room pressure regulation. Damper (round or rectangular) made of different material. All cables are pre-assembled ready to plug-in.
