Tips for Single and Double Tank Displays:
If the connection is obviously correct and malfunctions are suspected, please check the following:
Possible causes, if the displayed value is permanently < 10%:
a.
Cable 5 = Tank +, switched, to the tank transmitters, 12 V / 24 V:
Interrupted or short-circuited
Check
b.
Cable 4 = Measuring signal of the tank transmitter:
Short-circuited to ground
Check
Possible causes, if the displayed value is permanently 100%:
a.
Cable 1 = Board Battery “-“ or Body ground to the tank:
Interrupted
Check
b.
Cable 4 = Measuring signal of the tank transmitter:
Short-circuited to plus
Check
Performance Test Display: Release terminal 4 = measuring signal of the tank transmitter and connect
terminal 4 (for reasons of testing) to:
a.
Terminal 1 = Board Battery “-“ or Body ground
Display must drop to 3 %
b.
Terminal 5 = Tank +, switched
The display should increase to 100%
Then, the display function is basically correct, and the cause has to be searched with regard to the tank transmitter.
2 Tanks at one display:
The individual tank displays can also be assigned for selective measuring, such as
inside / outside tank, summer/winter operation, additional tank etc.
For switching, separate switches 2xUM are suitable, such as:
Switch Panel 16 A S
Order No. 1289
Switch Panel 2 x 16 A S Order No. 1291
With the double selector switches the cables
4 = Tank signal (measuring signal) and
5 = Tank + (Plus)
can be switched selectively to either of the tank measuring sensors.
The cables 1 = Board Battery “-“ (Minus) or Body Ground remain always connected.
Safety Regulations and Appropriate Application:
The unit has been designed according to the valid safety regulations.
Appropriate application is restricted to:
1.
Fused battery direct voltage with nominal voltage 12 V or 24 V.
2.
Technically faultless condition.

With a rear insulating cover of the display unit.
Never use the unit at locations where the risk of gas or dust explosion exists!
Cables are always to be laid in such a way that damage is excluded. Observe to fasten them tightly.
Never lay 12 V (24 V) cables and 230 V mains supply cables into the same cable conduit (empty conduit).
Check live cables or leads periodically for insulation faults, points of break or loosened connections. Occurring
defects must be remedied immediately.
Always disconnect the power supply to the battery prior to working on the electric system.
The unit is to be disconnected from any connection prior to electrically welding.
If the user is not able to draw from the manual, which characteristic values are valid for a unit or which
