Operation
The product monitors areas and signals accumulations of liquids. If one or
several photoelectric probes are submerged in liquid, the product signals an
alarm.
OM 5+1 additionally monitors for a minimum or maximum level.
If the floating probe is used for minimum level detection, the control unit trig-
gers an alarm as soon as the liquid level falls below the adjusted limit value.
If the floating probe is used for maximum level detection, the control unit trig-
gers an alarm as soon as the liquid level exceeds the adjusted limit value.
The operation of the product is limited to its regular monitoring:
•
The green LED is on.
•
The red LED is off.
•
The audible alarm is off.

Alarms
Leakage alarm:
If one or several photoelectric probes are submerged in liquid, the control unit
indicates that there is a leak (alarm).
In the case of a leakage alarm, the red LED is permanently illuminated and
the audible alarm is activated. The relay is energised and the alarm signal
can be transmitted to external equipment.
See "Spare parts and accessories" on page 35.
Level alarm (minimum/maximum)
The switching function of the floating probe is set via a coding plug in the con-
trol unit.
- If the floating probe is used for minimum level detection, the product sig-
nals an alarm if the float no longer floats on the liquid.
- If the floating probe is used for maximum level detection, the product
signals an alarm as soon as the float starts to float on the liquid.
In the case of a level alarm, the red LED flashes and the audible alarm is
activated.
In the case of simultaneous leakage alarm and level alarm, the red LED is
permanently illuminated and the audible alarm is activated. The number of
flash pulses of the yellow LED identifies the probe (1 to 6) which has trig-
gered the alarm. The flash pulses are repeated at intervals of approximately
three seconds.
