The CLE 3.1-mA is a sensor with a passive 4-20 A two-wire interface, i.e. the
power supply is external, e.g. via the controller.
Electrical installation
S Rotate the sensor adapter a quarter-turn anticlockwise and pull off
(bayonet fitting).
S Unscrew the locking screw of the PG 7 threaded connector and feed
through the signal cable from the controller.
S Strip the cable ends and connect to the 2-wire connector:
1 = plus, 2 = minus.
S Insert approx. 5 mm of the signal cable into the sensor and tighten the
PG threaded connector locking screw.
S Push the sensor adapter right into the housing and rotate carefully
clockwise until the stop. IMPORTANT not to break the tips of the bayonet
fitting.

IMPORTANT
Do not switch the measuring system off when using
intermittently. If necessary, use a timer to switch on metering
equipment.
IMPORTANT
 The probe is not electrically isolated from the sample
water. Ensure you electrically isolate from all other
consumers. The connected controller must be isolated
both from the sensor and from the power supply.
 Power supply must be at least 16 V at all times. Power
source must be able to supply 16 V DC at a min. 35 mA.
A power supply that is inadequate will provide incorrect
readings.
 Note the following when connecting to external devices:
Power source: 16-24 V DC, min. 35 mA at 16 V DC
Max. load: 1 W
