The control unit ICU is to be used in application where the electronic of the capacitive level indicators ICS or L-E3S must be placed in a remote installation.

The unit control ICU has to be allways connected to the capacitive indicator. When the level of product reaches the probe of the indicator, the control unit ICU reverses the signal due to a change of the capacity of the environment.

When the product disappear from the detection range, the signal turns to the initial position.

The control unit ICU has a regulation system that allow the adjustment of the sensitivity and a response time adjustment due to a nut in the electronic module.

It is simple: the device has to be installed in a DIN rail using the undecal socket. After electrical connection, the unit control has to be installed in the socket and proceed with the adjustements.
