2 139 Cannot
reach
position -
Hydraulic
box
indicates
error
Stop alarm The arm cannot reach specified
positions and the hydraulic power
box indicates that there is an error.
The pump unit has been switched
off and the hydraulic pressure is
thus reduced.
The system will try to clear the
alarm and resume operation. If this
fails, any ongoing milking session
will be completed, the cow
released and a self-test performed.
Automatic operation will be
resumed if the test is successful;
otherwise the stop alarm is issued.
Notify service engineer.
Service engineer only:
- Check that the hydraulic power unit is
switched on.
- Check oil level and oil temperature. Any
error concerning level and temperature is
indicated by the red lamps.
- If oil level and oil temperature is
sufficient/below limit, press the reset
buttons to restart the unit.
- If no fault can be found on the unit but the
alarm is issued anyway, it indicates that the
communication with the hydraulic power
unit is not working properly. Possible
causes might be (depending on the wiring
setup) the DVP vacuum pump, the option
box or the ALCOM bus.

2 140 Hydraulic
pump - too
high oil
temperature
Stop alarm Oil temperature has exceeded 60
deg C.
Check oil temperature on the analogue
thermometer. If it shows OK value, wait until
the oil temperature is lower than 55
degrees. It is important here the ambient
temperature is as low as possible. If the
true oil temperature appears to be much
lower than 60 degrees the digital
temperature sensor is possibly broken. It is
then possible to disable the sensor in
VmsConfig until the sensor is exchanged.
NOTE! The sensor will automatically be
enabled daily at 12.00.

2 141 Hydraulic
pump - too
low oil level
Stop alarm Too little hydraulic oil. Check the oil level in the monitor glass. If
the level is low, fill oil. If the oil level is OK,
the sensor may be broken. It is then
possible to disable the sensor in VmsConfig
until the sensor is exchanged.

Stop alarm Abnormally high pressure detected. The sensor is probably broken.
2 143 Hydraulic
pump - too
low oil
pressure
Deviation Abnormally low pressure detected. If the robot has "moving- problems", for
example cannot reach position, a service
technician possibly need to find the reason.
Possibilities are: pump error, motor or
unloading valve.

sensor failure
Stop alarm Temperature sensor is broken. Or
the cable or contact…
Check the electrical connection to the
sensor. Possibly change sensor. Until that
the sensor can be disabled in VmsConfig.

2 146 Hydraulic
pump - too
low oil
temperature
Stop alarm Measured oil temperature was
lower than 5 deg C when the
system wanted to start the pump.
The oil has probably too high
viscosity.
Check oil temperature on the analogue
thermometer. If it shows OK value, wait until
the oil temperature is higher than 5
degrees. If the sensor is broken, it is
possible to disable the sensor in VmsConfig
until the sensor is exchanged. NOTE! The
sensor will automatically be enabled daily at
12.00. If cold ambient temperature, maybe
enable boost mode.
