Safety instructions
!
Please read these instructions, carefully and completely, before putting the device into operation. Please also comply and follow the safety
instructions, specially the safety regulations related to the devices to be operated on mains supply. The product should be installed and used
only for the intended applications as described in these instructions. Any other application is not advised and shall lead to loss of guarantee
and exclusion from liability. This also applies to any changes or other modifications carried out on the device by the user. Mounting and ser
-
vicing operation should be carried out only after switching off the voltage.n The product is not meant for controlling electrical systems which
perform safety related functions. In normal operation also, there is always a danger of malfunctioning due to failure of any component or any
other disturbance. The user has to ensure that there are no consequential damages due to malfunctioning or undefined switching status of
the relay. This is all the more possible, if heavy loads like heaters or motors are triggered with the relays. The controller is only suitable for
mounting in dry locations. The liquids suitable for application of this device are all types of non-combustible, aqueous, non-corrosive and
unpolluted liquids e.g. tap water. The device is not suitable for combustible, non-conducting liquids!

Description
2.1
Functional description
The level controller is used for regulating level of conducting liquids like supply line water, rain water or condensate. The measurement
of level in the reservoir is done with the help of electrodes, for which either contact surface of the reservoir walls or self made rod type
electrodes can be used. With two independent circuits, simultaneous monitoring of both minimum and maximum liquid levels and control
of two different actuators are possible, for example, an inlet valve and a pump.
