ICS Tank is
filled up
completely
alarm level
reached
Stop alarm
Tank alarm.
The receiver tank is completely
filled up with milk or water.
Depending on the mode of the
tank system, there are two
possible causes for the alarm.
The tank system is in collecting
mode and the time between
emptying and cleaning of the
storage tank has been too long.
The receiver tank can not store
more milk.
The tank system is in cooling
mode and, for some reason, the
milk cannot be pumped from the
receiver tank to the storage tank.
- Stop the automatic milking system until
the storage tank can collect milk again.
(If AL7 can be removed the system is free
to function again)
- Check the power supply.
If the problem persists, contact service
engineer.
Service engineer only:
- Check output board signal. Check wiring
to contactor and pump. Check overload
protector. Check the output board fuse.
- Check if air pressure is available. Check
signals to pilot valves. Check pilot valves.
(Use P90 or the manual service key to
check individual valves.)
- Check level control (Use P91 – 1 low
level, P91 2 high level)
Cleaning mode: unpredictable. Check
cleaning.

ICS Too
long time no
cleaning
User
notification
Tank alarm.
The start cleaning signal is not
transmitted by the milking station
or is not received by the Hygenius
R125
Contact service engineer.
Service engineer only:
Check if the milking station transmits the
start cleaning signal.
Check if the signal is received by the
Hygenius R125 with use of P91 – 8.

ICS Valve in
wrong
position
Stop alarm
Tank alarm.
The signal from one of the
proximity switches fails.
Contact service engineer.
Service engineer only:
- Check the position of the milk valve.
If closed P91 – 4 must be 1.
- Check the position of the drain valve.
If closed P91 – 5 must be 1.
- Check the position of the pick-up valve.
If closed P91 – 6 must be 1.
If one of above fails replace the proximity
switch. If not, check the pilot valves and
pressurised air supply.
A valve must be in the wrong position for
the desired operation.

been out of order. If too long time has
elapsed, pump the milk to drain and
perform a cleaning manually.
b) Restart the cleaning manually.
