Due to the possible occurrence of an electrostatic charge on the non-conductive parts of

the sensor, it is necessary to ground all sensors intended for use in environments with an

explosion hazard (type CPS-24Xi). This can be performed by grounding el. conductive tanks

or el. conductive tank lids, and in the case of el. non-conductive tanks using and grounding

an auxiliary plate electrode PDE-27.

In the event that the water level meter (sensor) is installed in an outdoor environment at a

distance greater than 20 m from the outdoor switchboard, or from an enclosed building, it

is necessary to supplement the electrical cable leading to the water level meter (sensor)

with suitable overvoltage protection.

In the event of strong ambient electromagnetic interference, paralleling of conductors with

power distribution, or for distribution to distances over 30 m, we recommend using a shielded

cable and grounding the shielding on the side of the power source.

6 . Settings

The sensitivity is set by trimmer located under cover screw on the rear side. Clockwise turning

makes the sensitivity lower, reverse direction turning makes the sensitivity higher.

SETTING THE BASE SENSITIVITY:

a) Type CPS-24_-_-_O:

Turn the trimmer to the left until the LED is lit. Then turn slightly to the right until the LED just

turns off. From this point, turn 180° to the right.

b) Type CPS-24_-_-_C:

Turn the trimmer to the left until the LED turns off. Then turn slightly to the right until the LED is

lit. From this point, turn 180° to the right.

After setting the sensitivity, do not forget to properly tighten the trimmer cover screw.

The base sensitivity of the sensor is factory set (sensing distance on the metal surface) 8 mm. The

actual sensitivity (sensing distance) depends on the dielectric properties or where appropriate the

conductivity of the sensed material.

For sensing of materials with a low relative permittivity (plastics), we recommend to individually set

a higher sensitivity, or consult with the manufacturer if necessary.
