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 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.

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).

2...10V DC corresponds to an exhaust air volume flow of 0...2000m³/h.
The analogue input on terminals X9.19 (GND) and X9.20 (0...5/10V
DC) is free and reserved for special functions.
Combined supply air and exhaust air control can be achieved with this
input, for example. The maximum input current is 1mA.

CONNECTING THE
FLOW SENSOR
Exhaust
air
The air flow sensor measures the flow velocity in the fume hood.
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).

The meaning of the relay outputs K1 to K3 is as follows:
6.6.1
CONNECTING THE LIGHT RELAY (K3)
The Light relay (K3) is activated when the Light on/off button on the function display 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 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.

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.
