Type Type Meaning Meaning
The arm cannot reach specified The arm cannot reach specified
positions and the hydraulic power positions and the hydraulic power
box indicates that there is an error. box indicates that there is an error.
The pump unit has been switched The pump unit has been switched
off and the hydraulic pressure is off and the hydraulic pressure is
thus reduced. thus reduced.
The system will try to clear the The system will try to clear the
alarm and resume operation. If this alarm and resume operation. If this
fails, any ongoing milking session fails, any ongoing milking session
will be completed, the cow will be completed, the cow
released and a self-test performed. released and a self-test performed.
Automatic operation will be Automatic operation will be
resumed if the test is successful; resumed if the test is successful;
otherwise the stop alarm is issued. otherwise the stop alarm is issued.
Oil temperature has exceeded 60 Oil temperature has exceeded 60
deg C. deg C.
Too little hydraulic oil. Too little hydraulic oil.
Abnormally high pressure detected. Abnormally high pressure detected.

alarm is issued anyway, it indicates that the alarm is issued anyway, it indicates that the
communication with the hydraulic power communication with the hydraulic power
unit is not working properly. Possible unit is not working properly. Possible
causes might be (depending on the wiring causes might be (depending on the wiring
setup) the DVP vacuum pump, the option setup) the DVP vacuum pump, the option
