6.3.3 Monitoring functions
The following functions are available for moni-
toring the lubrication system:

Fill level monitoring

Monitoring the lubrication cycle via
piston detector

Monitoring signal cables for cable
breakage and monitoring valves and
piston detectors

Monitoring switch outputs for short circuit

Monitoring power consumption of the
pump motor

Monitoring the temperature in the
pump unit

Diagnostics memory (real-time)
6.3.3.1 System monitoring
This function includes the following monitoring
functions:
• Fill level monitoring
• Monitoring the lubrication cycle
via piston detector
System monitoring can be activated and
deactivated. The monitoring functions men-
tioned above are deactivated when system
monitoring is deactivated. This means that no
fault notiication is issued if, for example, the ill
level in the lubricant reservoir falls below the
"min" mark.
It only makes sense to deactivate system
monitoring if the functions mentioned above
cannot be used because the required sensors
are not connected.
6.3.3.2 Fill level monitoring
Depending on the lubricant, either mechanical
or capacitive sensors are used to monitor the
ill level in the lubricant reservoir. In the stan
-
dard design, a mechanical sensor (W1 or W1G)
monitors whether the lubricant falls below the
"min." mark. This is preferred for use with
greases of NLGI Grade 2.
For NLGI Grade ≤ 1 greases, a capacitive sen
-
sor (W2) is provided which is integrated into
the reservoir cover. The sensor sends a signal
to the control unit if the lubricant level reaches
the "min" mark. The control unit then gener-
ates a fault notiication (see Chapter 15).
Fault notiications due to insuficient
ill level are only issued when system
monitoring is active.
