Function And Features; Mounting - IFM Electronic efector 300 VS 0200 Notice D'utilisation

2. Function and features

The control monitor VS 0200 is designed to work with flow sensors. The con-
trol monitor evaluates the signals from the sensors and signals whether there
is a preset flow rate or not:
- Flow above the preset value / output relay is energised
- Flow below the preset value / output relay is de-energised
• Flows of either liquids or gases can be monitored.
• Additional options (only for the corresponding monitor version):
- Wire break monitoring: in the case of an open-circuit or short-circuit the
monitoring relay is de-energised, the red LED signals a fault.
- Temperature monitoring: relay is energised when temperature is exceeded,
the red LED signals a fault.
The monitor is not approved for safety tasks in the field of safety
of persons.

3. Mounting

Mount the unit in a control cabinet with a protection rating of at least
IP 54 to guarantee protection against accidental contact with voltages
and against atmospheric influence. The control cabinet should be
installed in accordance with local and national rules and regulations.
Mount the unit on a DIN rail or by means of a mounting base. Once mounted
leave enough space between the unit and the top and bottom of the control
cabinet (to enable air circulation and to avoid excessive heating).
When several units are mounted side by side the internal heating of all units
has to be considered. The ambient temperature for the individual unit must not
exceed the permissible value of 60°C.
Prevent the penetration of conductive or other dirt into the housing or wiring.
Mounting of the sensors:
Adhere to the mounting instructions of the manufacturer.
