LUBRICATION SYSTEM
The minimum level switch
A minimum level switch monitors the grease level in
the reservoir. When the grease reaches the minimum
level, the minimum level switch will notify the control
unit.
After “X” cycles, the pump stops to avoid it to work
empty.

Introduction
To test the greasing system two different test cycles
can be carried out with the test push-button on the
grease pump unit:
1. The single test cycle /through teh A or B grease
line).
2. The continuous test cycle (successive greasing
cycles through the A and B grease lines).

The single-test cycle
Proceed as follows to carry out a single-test cycle:
1. Turn on the contact switch.
2. Push the test push-button on the pump for at least 2 seconds, but no longer than 6 seconds.
The codes and errors can be check through CanBus PC.
The single-test cycle ends after the pressure decrease phase or when the contact is turned off. When the
contact switch is turned on again the program will always begin with the pause phase of the cycle that just been
interruped.
ATTENTION:
Remember that a single-test cycle only tests one of the primary grease lines.
To test the other primary grease line, a second single-test cycle has to be carried out.
