Function and features

The evaluation system VS3000 is designed to work with flow sensors
of the type SFxxxx. It evaluates the signals from the sensors and sig-
nals 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.
• Wire break monitoring: in the case of an open-circuit or short-cir-
cuit the monitoring relay is de-energised, the red LED (WIRE
BREAK/RELAY) signals a fault.
• Temperature monitoring: relay is energised when temperature is
exceeded, the red LED (TEMP/RELAY) signals a fault.
The unit is not approved for safety tasks in the field of safety of
persons.

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 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).
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.
