2.1 FUNCTION DISPLAY AND CONTROL PANEL

For use as a monitoring and alarm system for exhaust air volume fl ows in various applications, such as fume hoods, safety cabinets and other extraction units.

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 fl ow falls below the programmable thresholds. When the threshold is exceeded, only an optical alarm is signalled (yellow LED).

FM100 fulfi lls 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 retrofi t existing fume hoods.

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 retrofi tting) 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-specifi c 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 insuffi cient exhaust air or

excess supply air (when used for supply air monitoring)� Optical display (OK=green LED) for suffi cient 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 fl ashing 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


FUNCTIONAL DESCRIPTION

The FM100 fume hood controller complies with the safety requirements of the EMC law and the CE Marking Directive and therefore disposes of a CE Mar-king.

The electrical connection must be carried out by a qualifi ed electrician and safety regulations and the VDE guidelines must be followed.

The power feed-in generates the supply voltage for the control electronics. Check whether the operating voltage shown on the nameplate corresponds with the supply voltage at the site where the device will be installed.

Important!It is essential to ensure that PHASE, ZERO and EARTH are connected correctly!Ensure proper protection against short circuiting!

Follow the safety regulations at all times: - Disconnect the FM100 fume hood monitor - Ensure that the controller cannot be switched on again - Ensure that the controller is voltage-free - Connect the mains connector (230 VAC) with a 3x1,5mm² cable

If supplied, connect the emergency power pack. 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 fl ashing LED and acoustic alarm). This alarm cannot be acknow-ledged. 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.

The motor on recognition function can be activated or deactivated via the ser-vice module SVM100 or laptop (see Chapter 8.0 Programming instructions).

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 fl ow for the fume hood that is connected to it.

When the exhaust fan is switched off (no current on terminal connector X2.2 and X2.3) the FM100 controller is deactivated (red LED is on, the acoustic alarm and and all other LEDs are off), i.e. an optical alarm is only signalled when the exhaust fan is switched off (=without current).

The mains voltage (230V AC) of the corresponding exhaust fan can be directly connected to terminal X2.2 and X2.3.

Important!It is essential to ensure that PHASE and ZERO are connected correctly!Ensure proper protection against short circuiting!

Optionally terminal input X2.2 and X2.3 is also available for a voltage of 24V AC (please request this on your order).

The following additional functions can be implemented with the digital inputs on terminal block X9.

The digital inputs In 1, In 2 and In 3 have no galvanic separation. Activation is done directly via potential-free contacts.

With activation via potential-free contacts the maximum cable length is limited to 5m. The current per input is ≤ 2mA (bei 5V DC).

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 switching of the control setpoints via terminal X9.15 and X9.16. The Day and Night control setpoint is programmed via the service modu-le SVM100 or laptop (see Chapter 8.0 Programming instructions).

The Day setpoint controls safe exhaust air volume fl ow during daytime opera-tion, while the fume hood‘s Night setpoint controls the fume hood during night-time operation (reduced operation). That means that during reduced operation an alarm is only signalled when the reduced exhaust air volume fl ow falls below the Night setpoint.

When the contact is open the FM100 fume hood monitor is in Day setpoint con-trol 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.

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 me-chanical lock must be released. In accordance with this standard, a fl ashing 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“ fl ashes 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).

CONNECTING THEFLOW SENSOR

6.5

The air fl ow sensor measures the fl ow velocity in the fume hood. The FM100 fume hood controller has two different monitoring op-tions:

1. Monitoring of safe exhaust air volume fl ow2. Monitoring of safe fl ow velocity

The static differential pressure transmitter and the necessary measuring system is not required if the fl ow sensor is used. Low fl ow 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 fl ow sensor and air temperature changes may distort the measuring result.

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 infl u-ence on the result of the volume fl ow measurement. This method is therefore well established for measuring low volume fl ows (=low fl ow velocities).

INSTALLATION • RELAY OUTPUTS

6.6 CONNECTING THERELAY OUTPUTS

The complete system is populated with max. 3 relays. The potential-free relay outputs are for malfunction notifi cation and feedback to the building services management system. The maximum ohmic contact load of the relay Light K3 is 12 A (230V AC), which means that it is also suitable for controlling fl uorescent tubes. The maximum ohmic contact load of the relay K1 and K2 ist 3 A (230V AC).

Important! Ensure that connected consumer loads are properly protected against short circuiting!

The meaning of the relay outputs K1 to K3 is as follows:

The Light relay (K3) is activated when the Light on/off button on the function dis-play and control panel is pressed and is inactiveted when the button is pressed again. 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 fl uorescent light is connected to terminal X3.L (phase L), X3.N (neutral) and X3.earth.

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 activa-tion 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).

In the case of a fault alarm, the Alarm relay (K1) drops out and thus signals the malfunction status. Malfunctions may be, for example, insuffi cient exhaust air volume, mains voltage failure and internal errors.

In some cases client-specifi c 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.

Programming of project-specifi c data is done via the service module SVM100 or PC. Plug the service module data cable into the service plug of the function display and plug in the service module mains plug. The fume hood controller power supply must also be switched on.

After selecting the FM product from the main menu with the F1 button on the service module, the following settings are available for selection:

When steps 1 to 11 have been programmed and checked, the FM100 fume hood monitor is ready for use. All settings are saved mains voltage failure-safe.

The programming instructions described here are for the service module SVM100. If programming of the FM100 fume hood monitor is carried out via PC/laptop and the SCHNEIDER software PC-2000 the settings and their explanations are identical.

The programming options of the service module SVM100 are clearly structured. The buttons needed are described be-low.

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


Setting range

The shield factor is necessary to calculate the exhaust air volume fl ow (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 effi cient functioning of the FM100 fume hood mo-nitor.

The following table illustrates the relationship between the Venturi measuring tube from SCHNEIDER the nominal diame-ter (DN), the C-value (C), the shield factor (B) and the overall length (L).

Flow hood with measuring tube

Using a SCHNEIDER measuring tube, determination of the volume fl ow 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.

Depending on the model and the connection diameter (DN), each type of fume hood also has a specifi c shield factor (C value). This can easily be calculated using the measuring reports that are available for each fume hood type.

Calulation formula:

Assumption:Air density ς = 1.2 kg/m³

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 fl ow of 480 m³/h.

Thus C is calculated as:

and the shield factor S:

Set the calculated value of 59 for this type of fume hood.

480C = = 74

42

B = 74 0,8 = 59

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.

The piezo duration defi nes 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 predefi ned piezo duration (automatic alarm acknowledgement) or it can be switched off manually (manual acknowledgement) by pressing the acknowledge-ment button (Reset). Setting 900 suppresses automatic acknowledgement and allows only manual acknowledgement.

8.7 Set the motor on recognition


Setting range

Motor-On On/OffENT

-+

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).



8.8 Alarm delay after start-up

Menu item in service module

Setting [s]

Delay start 5 to 120ENT

-+

ENT

After start-up, the red LED (underrun) always lights up fi rst. 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 malfunc-tion 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 fl ow rate after a specifi c period of time. The alarm delay time after start-up is entered in seconds.

8.9 Defi ne the switch type „Sash > 50cm“


Type selection

Switch type NC/NOENT

ENT

The switch type on terminal X7.13 and X7.14 is defi ned 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 fl ashing 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“ fl ashes on the function display.

The delay time defi nes 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.


MAINTENANCE • TROUBLESHOOTING

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.

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 fi rst) with a redundant measuring value (hot-wire or vane anemometer).

The 6V/1.2 Ah power pack must undergo maintenance checks at regular inter-vals and must be exchanged after a maximum of fi ve years. The FM100 fume hood monitor has an integrated power pack charging connection.

PROBLEM CAUSE
