[WARNING BATTERY]
The realtime clock battery is exhausted.
Change realtime clock module
[WARNING OPTION 1]
[WARNING OPTION 2]
[WARNING OPTION 3]
One of the spare inputs 1-3 has been
activated but is programmed as [FREE].
Check relevant input assignment

[FAULT POWER LOSS 20V]
20V supply of control power transformer
has failed.
Check control-power transformer and
fuses.
[FAULT LEVELSWITCH]
Both level switches closed (not mechanically
possible).
Check level switches and their wiring.
[FAULT DRAINAGE 1]
Fault in water exchange:
No feedback from level switch that the water
level has reached the bottom limit.
Check level switches and wiring
Check solenoid value for water
drainage
Check control transformer for solenoid
valves
Set DRAINAGE MAX. higher.
(6)
[WARNING SUPPLY 2]
Fault in water exchange:
No feedback from level switch that the water
level is increasing.
Check whether the water supply of the
machine is guaranteed; the water
pressure may be too low.
Check whether there is enough water
in the tank of the water treatment unit.
Check level switch and wiring.
Check solenoid valve for water inlet.
Check control transformer.
Set SUPPLY MAX. higher.

[FAULT SUPPLY 2]
Fault in water exchange:
The WARNING SUPPLY 2 occurred twice in
a row and was not acknowledged.
See WARNING SUPPLY 2
[WARNING SUPPLY 3]
Fault in water exchange:
No feedback from level switch that the water
level has reached the upper level.
See WARNING SUPPLY 2
[FAULT SUPPLY 3]
Fault in water exchange:
The WARNING SUPPLY 3 occurred twice in
a row and was not acknowledged.
See WARNING SUPPLY 2
[FAULT DRAINAGE 4]
Fault in water exchange:
No feedback from level switch that the water
level has dropped.
See FAULT DRAINAGE 1
[WARNING SUPPLY 5]
Fault in automatic water level
regulation (no water exchange active):
No feedback from level switch that the water
level is increasing.
See WARNING SUPPLY 2

[* Wrong SR-Serial Number]
[SETUP-CODE 1:_______?]
The serial number of the SR drive resident
in DELCOS 3100 does not concur with the
serial number read out from the SR drive.
The electronics PCB’s may have been
swapped in the SR drive.
Re-enter setup code.
[*** Wrong SR-Mode ***]
[SETUP-CODE 1:_______?]
The mode of the SR drive resident in
DELCOS 3100 does not concur with the
mode read out from the SR drive. The
