7.3.4 Monitoring functions
The following functions are available for moni-
toring the lubrication system:
Fill level monitoring
Pressure build-up monitoring
Pressure reduction monitoring
Monitoring signal cables for
cable breakage and monitoring valves and
piston detectors
Monitoring outputs for short circuit
Monitoring power consumption of the
pump motor
Monitoring the temperature in the
pump unit
7.3.4.1 Fill level monitoring
Depending on the unit design, either mechani-
cal or capacitive sensors are used to monitor

can be used to generate a pre-warning so the
operator is prompted to top up in time.
The sensor sends a signal to the control unit if
the lubricant level reaches the "min" mark. The

7.3.4.2 Pressure build-up monitoring
(single-line systems)
The pressure switch monitors whether the re-
quired pressure buildup occurs in the lubrica-
tion line during the pump cycle time. A signal is
sent to the control unit when the set pressure
is reached. The signal from the pressure switch
can be used to control the pump cycle time. If
