Operation
After mounting, wiring and setting check whether the unit operates
correctly.
The flow monitor indicates errors by 2 signals:
a) outputs alternative: on, off, on, off,
b) the LED fluctuate from red to green and back.
The following errors are indicated in this way:
• When flow is switched on, the maximum flow rate is not reached.
• When flow is switched off, flow is not completely stopped (low
flow rate remains).
• Faulty setting of the unit.
Recommended maintenance
Check the sensor tip for build-up from time to time. Clean it with a
soft cloth. If necessary, build-up which adheres firmly (e.g. lime) can
be removed with a common vinegar cleansing agent.
The units are suitable for use in moderate electromagnetic fields (see
table). When operating ISM equipment or powerful walkie-talkies in
the vicinity of the units additional measures to avoid malfunction can
be required.
