Green 4 = Tank Signal
brown 1 = Battery -
The tank sensor MT is protected against any kind of reverse battery connection. It is recommendable to use
connection cables of different colours to avoid malfunctions due to mixed up connections. As soon as the
display unit has been installed according to the operating manual, the battery can be connected.
Adjustment:
The adjuster at the upper side of the tank sensor is used to adjust the tank height to 100% "FULL" at the
display:
Measure the exact tank depth (inside depth) through the mounting hole of the tank with a ruler and set the
adjuster for the "water depth" to this value. The adjustment procedure is completed.
The functions of the display can now be simulated with several water levels in the tank (or in a bucket being
filled with water) or by withdrawing the tank electrode out of the full tank (or bucket).
Fine adjustment of the set water depth can be corrected or changed at any time with full tank.
Final Installation:
The delivered sealing washer is placed between tank and casing flange. Screw the tank transmitter in place
using the coupling ring.
In case of underfloor installation of the tank, the adjuster must be protected with a permanently elastic sealant
against aggressive environmental influences (de-icing salt etc.).
Example:
The scale indicates the value
18cm as adjusted tank height
