Okay Air volume or Air velocity green Alarm Okay red green Overshoot yellow oberer Grenzwert Actual value Microprocessor controlled security system to monitor the containment-safe operating status of fume hoods. An acoustic and optical alarm is activated as soon as the exhaust air volume flow falls below the programmable thresholds. When the threshold is exceeded, only an optical alarm is signalled (yellow LED). FM100 fulfills the standards DIN 12924, Part 1 and EN 14175, Part 2. That means security for the laboratory worker. FM100 is suitable for all types of fume hood, making it easy to implement new installations and retrofit existing fume hoods. unterer Grenzwert time 2.1 FUNCTION DISPLAY AND CONTROL PANEL A suitable measurement system is vital for precise and safe monitoring. For safe operation with the static differential pressure transmitter and reproducible and exact measurement results we recommend the SCHNEIDER measuring tube (suitable for retrofitting) or the SCHNEIDER venturi measuring tube. The function and control panel is available with its own case or as a built-in version in different variations. In addition to client-specific designs a wide range of different function displays are available (see the data sheet Standard function displays). Basic functions: Acoustic and optical alarm (LOW=red LED) for insufficient exhaust air or excess supply air (when used for supply air monitoring) Optical display (OK=green LED) for sufficient exhaust/supply air RESET button to acknowledge the acoustic alarm Service plug for programming via the service module SVM100 or laptop Addition optional functions: Button VMAX only for SCHNEIDER fume hood controllers Optical display (HIGH=yellow LED) for exceedance of the maximum exhaust air Yellow flashing LED as an optical alarm for the operating status “Sash > 50cm” Status display VMIN for day/night display Button Light ON/OFF (fume hood interior) Button I/O for switching the control function ON or OFF Function display type: 0010 4 Operating Manual ● FM100 FUNCTIONAL DESCRIPTION Battery backup FUNCTIONAL DIAGRAM 2.2 PERFORMANCE FEATURES 2.3 CE NOTES 2.4 2 1 + Fume hood monitor p FM100 230 VAC Power Day/Night operation Digital In-/Outputs 4 Analogue Output 5 3 Fume hood Functional display Air volume display High m3 h Okay 6 Low Reset RS 232 Monitoring according to EN 14175 Servicemodule SVM-100 Supply air 1 Venturi measuring tube 2 1 2 3 3 Static differential pressure transmitter or alternate Air flow sensor 4 5 6 4 Digital In-/Outputs for special application 7 8 9 5 Analogue Output (0...10 VDC) for room group controller * 0 , 6 Optional air volume (m3/h) or air flow (m/s) display F1 F2 F3 Laptop Microprocessor controlled monitoring system Integrated power supply 230V AC All system data are saved mains voltage failure-safe in the EEPROM Programming and retrieval of all system values via the service module SVM100 or software PC2000 Monitoring of supply air and exhaust air systems Static differential pressure transmitter with high long-term stability.

The red wire is connected to the positive pole (+) and the blue (black) wire to the negative pole (-). According to the standard EN 14175 an emergency power pack is no longer compulsory. In the case of a mains voltage failure the emergency power pack provides the supply voltage for the fume hood controller. A mains voltage failure alarm is signalled (red flashing LED and acoustic alarm). This alarm cannot be acknowledged. With a 6V/1.2 Ah emergency power pack the FM100 mains voltage failure alarm remains active for at least 4 hours (provided that regular annual maintenance is carried out on the power pack). Important! When connecting the emergency power pack it is essential to ensure that the polarity (+) and (-) is correct! The components required for basic functioning have now been connected. If no further additional functions or relay outputs are needed, you can now move on to the programming instructions (Chapter 8.0). The terminal connections for the additional functions and relay outputs are described from Chapter 6 onwards.

When the motor on recognition is activated (= On) terminal block X2 is checked to see whether the exhaust fan is switched on (230V AC on terminal X2.2 and X2.3). When the exhaust fan is switched on the FM100 fume hood controller is ready for use and controls the safe exhaust air volume flow for the fume hood that is connected to it.

Run Operating Manual ● FM100 INSTALLATION • DIGITAL INPUTS • ADDITIONAL FUNCTIONS On/Off (In 1) 6.2.1 Switches the FM100 fume hood controller ON and OFF via terminal X9.17 and X9.18. When the FM100 is switched on, the relay K2 Motor on/off is activated. When the contact is open the FM100 fume hood controller is switched on, while a closed contact switches the device off (relay K2 Motor on/off drops out). This relay serves as feedback to a building services management system (BSM) or for direct activation of an exhaust fan (via a contactor). Daytime/night-time control (In 2) 6.2.2 Daytime/night-time switching of the control setpoints via terminal X9.15 and X9.16. The Day and Night control setpoint is programmed via the service module SVM100 or laptop (see Chapter 8.0 Programming instructions). The Day setpoint controls safe exhaust air volume flow during daytime operation, while the fume hood‘s Night setpoint controls the fume hood during nighttime operation (reduced operation). That means that during reduced operation an alarm is only signalled when the reduced exhaust air volume flow falls below the Night setpoint. When the contact is open the FM100 fume hood monitor is in Day setpoint control mode, while a closed contact switches the device to Night setpoint control mode. A relay as feedback for the building management system (BMS) is only supplied with the FM500 model. Sash >50cm (In 3) 6.2.3 According to EN 14175 fume hood sashes must be equipped with a mechanical lock at a sash opening of 50cm. If the sash is opened more than 50cm, the mechanical lock must be released. In accordance with this standard, a flashing LED on the function display signals the condition „Sash opening > 50cm“ (alarm). When the contact on terminal X9.13 and X9.14 is open (switch type=normally closed contact) or shut (switch type=normally open contact) the LED „Close sash“ flashes on the function display. The switch type (normally closed contact or normally open contact), the acoustic alarm delay time as well as an acoustic alarm in addition to the optical alarm can be programmed via the service module SVM100 (see Programming instructions, steps 8.9, 8.10 and 8.11).

The FM100 fume hood controller has two different monitoring options: 6.5 1. Monitoring of safe exhaust air volume flow 2. Monitoring of safe flow velocity AIR FLOW SENSOR The static differential pressure transmitter and the necessary measuring system is not required if the flow sensor is used. Low flow velocities of 0,3 m/s can be monitored, whereby this system is very vulnerable to disturbance variables, i.e. air turbulence, the type of fume hood, the installation point of the flow sensor and air temperature changes may distort the measuring result. Fume hood A considerably more robust and accurate measuring method is a static differential pressure transmitter with a suitable measuring system. The disturbance variables mentioned above have no influence on the result of the volume flow measurement. This method is therefore well established for measuring low volume flows (=low flow velocities).

With this relay the lighting in the fume hood is switched on and off. The phase is switched from terminal X1.1 to X3.L via the relay contact K3 and may be a separate mains from the power line (3 phases). When the phase is the same, terminal X1.L is bridged to X1.1. The fluorescent light is connected to terminal X3.L (phase L), X3.N (neutral) and X3.earth. 6.6.2 CONNECTING THE MOTOR ON RELAY (K2) The Motor on/off relay K2 is activated when the FM100 fume hood controller is switched on. This may be done by pressing the I/O (in/out) button (if this function is enabled) on the function display and control panel or via the remote activation input X9.17 and X9.18 (see digital inputs). The digital in/out output has a higher priority than the button and overrides it. This relay switches the exhaust fan on or off and also serves as feedback for the building management system (BMS). 6.6.3 CONNECTING THE ALARM RELAY (K1) In the case of a fault alarm, the Alarm relay (K1) drops out and thus signals the malfunction status. Malfunctions may be, for example, insufficient exhaust air volume, mains voltage failure and internal errors. 14 Operating Manual ● FM100 FUNCTION DISPLAY AND CONTROL PANEL FUNCTION DISPLAY AND CONTROL PANEL 7.0 In some cases client-specific function and display panels require a different arrangement of the elements on the function display and control panel than the universal function display panel shown here. However, the operation and meaning of the functions is exactly the same and can therefore be compared with the universal function display panel. With complex function display panels like the one shown here, the jumper JP1 must be plugged to serial, while with simple function display panels (two LEDs, a Reset button and a service plug) the jumper JP1 must be plugged to parallel.

CAUTION! Detach both measuring hoses if zero-point calibration is to be performed. Press the SPACE key to cancel the zero-point calibration and the ENTER key to carry out the zero-point calibration. 8.3 Shield factor of the measuring system and fume hood type Menu item in the service module Setting range + Shield factor - 10 to 250 ENT ENT The shield factor is necessary to calculate the exhaust air volume flow (actual value). This actual value is constantly compared with the programmed setpoints. If the setpoints are exceeded or underrun, an alarm or warning message is signalled. Selection of the correct shield factor is very important for the efficient functioning of the FM100 fume hood monitor. The following table illustrates the relationship between the Venturi measuring tube from SCHNEIDER the nominal diameter (DN), the C-value (C), the shield factor (B) and the overall length (L).

The shield factor must be programmed. It is calculated on the basis of the C value (C) of the measuring system used, whereby: B = C • 0,8 Operating Manual ● FM100 17 PROGRAMMING INSTRUCTIONS Using a SCHNEIDER measuring tube, determination of the volume flow and measuring accuracy can be considerably improved. The differential pressure will be measured room pressure independend on the masuring tube. The static differential pressure transmitter is connected to the (+) connector and the (-) connector of the measuring tube. - Connection p Differential pressure + Connection Measuring tube + Depending on the model and the connection diameter (DN), each type of fume hood also has a specific shield factor (C value). This can easily be calculated using the measuring reports that are available for each fume hood type. Flow hood with measuring tube Calulation formula: C = Assumption: Air density ς = 1.2 kg/m³ V p C = Shield factor (C-value) V = Air volume flow [m3/h] P = Differential pressure [pa] The shield factor required for fume hood control is calculated as follows: B = C 0,8 Sample calculation: From your test report you establish that the fume hood has a static pressure loss of 42 pascal (pa) at a volume flow of 480 m³/h. Thus C is calculated as: C = 480 = 74 42 B = 74 0,8 = 59 and the shield factor S: Set the calculated value of 59 for this type of fume hood. 8.4 Enter setpoints for the volume flows Menu item in the service module Settings [m3/h] Submenu items + Setpoint cbm/h ENT ENT Minimum day F1 F1 0 to 2500 Maximum day F2 F2 0 to 2500 Minimum night F3 F3 0 to 2500 Maximum night F4 F4 0 to 2500 - ENT Enter the underrun value (Minimum day F1) and, if necessary, the exceedance value (Maximum day F2) for daytime operation in m³/h. To monitor in night-time reduction mode (reduced operation = non-working time) enter the appropriate underrun (Minimum night F3) or exceedance (Maximum night F4) value for reduced operation as well. 18 Operating Manual ● FM100 PROGRAMMING INSTRUCTIONS 8.5 Set the alarm delay time Menu item in the service module Settings [s] + Delay time ENT - 1 to 240 ENT The alarm delay time defines how long the predefined setpoint must be underrun or exceeded before an alarm or warning is signalled. The delay time is entered in seconds. 8.6 Set the duration of the acoustic alarm Menu item in the service module Submenu item Settings [s] + Piezo setting ENT Piezo duration F1 - 10 to 900 F1 ENT ENT The piezo duration defines how long an acoustic is signalled before it is automatically acknowledged. This is entered in units of 10 seconds. When an acoustic alarm is signalled, either it switches off automatically after the predefined piezo duration (automatic alarm acknowledgement) or it can be switched off manually (manual acknowledgement) by pressing the acknowledgement button (Reset). Setting 900 suppresses automatic acknowledgement and allows only manual acknowledgement. 8.7 Set the motor on recognition Menu item in the service module Setting range + Motor-On ENT - On/Off ENT The Motor on recognition is used to recognize and analyze various operating modes of the fume hood controller. Motor on recognition OFF The control function is always active. An alarm (optical and acoustic) is signalled when the ventilation system is shut down. Motor on recognition ON The control system is only active when the Motor on signal (230V AC, optionally 24V AC) is connected to terminal X2.2 and X2.3 (ventilation system is switched on). If a Motor on signal is not present, only an optical and not an acoustic alarm is signalled (ventilation system is switched off). Operating Manual ● FM100 19 PROGRAMMING INSTRUCTIONS 8.8 Alarm delay after start-up Menu item in service module Setting [s] + Delay start ENT - 5 to 120 ENT After start-up, the red LED (underrun) always lights up first. When the volume of air reaches or exceeds the underrun threshold, the green LED lights up and the red LED goes out. During the predetermined alarm delay time the malfunction relay K1 does not drop out even if the volume of air is too low. It is only activated after the predetermined time (5 to 120s). This is true for all for methods of switching on and over: Connection of the supply voltage Button On/Off Signal Motor on Switch to Day/night This function does not generate an alarm for example, if the exhaust fan is switched on but only reaches its full volume flow rate after a specific period of time. The alarm delay time after start-up is entered in seconds. 8.9 Define the switch type „Sash > 50cm“ Menu item in the service module Type selection + Switch type ENT - NC/NO ENT The switch type on terminal X7.13 and X7.14 is defined as a normally closed contact (NC) or a normally open contact (NO). According to EN 14175 fume hood sashes must be equipped with a mechanical lock at a sash opening of 50cm. If the sash is opened more than 50cm the mechanical lock must be released. In accordance with this standard, a flashing LED on the function display signals the condition „Sash > 50cm“ (alarm). When the contact on terminal X9.13 and X9.14 is open (switch type=normally closed contact) or shut (switch type=normally open contact) the LED „Close sash“ flashes on the function display. 20 Operating Manual ● FM100 PROGRAMMING INSTRUCTIONS 8.10 Set the piezo Sash > 50cm on/off Menu item in the service module Setting + Piezo sash ENT - On/Off ENT For a sash opening > 50cm an acoustic alarm (=On) can be programmed in addition to the optical alarm. 8.11 Set the delay time Sash > 50cm Menu item in the service module Settings [min] + Delay time ENT - 1 to 240 ENT The delay time defines how long the contact on terminal X9.13 und X9.14 must be open (switch type=normally closed contact, NC) or shut (normally open contact, NO) before an acoustic alarm (see 8.10 Piezo sash) is signalled. The delay time is entered in minutes. The optical alarm is signalled directly without delay. Operating Manual ● FM100 21 MAINTENANCE • TROUBLESHOOTING 9.0 MAINTENANCE The FM100 fume hood monitor requires no special maintenance. However, you must ensure that the PVC measuring hoses are not damaged or buckled and that they are securely attached to the measuring system and the sensor. 9.1 ANNUAL FUME HOOD MAINTENANCE Annual fume hood maintenance must include a function test that signals the acoustic and optional alarm (detach the measuring hoses). Following zero-point calibration of the differential pressure transmitter (only to be carried out when the measuring hoses are detached), see Chapter 8.2, the setpoints must be checked via the service module or laptop. Finally, select the menu item Actual value in the SVM100 service module and compare the exhaust air actual value (reattach the measuring hoses first) with a redundant measuring value (hot-wire or vane anemometer). 9.2 POWER PACK The 6V/1.2 Ah power pack must undergo maintenance checks at regular intervals and must be exchanged after a maximum of five years.
