Automatic Greasing System Twin-3
EG1703P03
3 S ystem test
3.1 Introduction
To test the greasing system two different cycle tests can be performed with the test push-button
on the pump or with switch-button at the Twin-3 display (see Figure 3.1 and Figure 3.2):
1. The single cycle test (through line-A or -B).
2. The multiple cycle test (continuous cycles through line-A and -B).
A cycle test can only be performed if the greasing system is performing the pressure retaining
phase, the pressure decrease phase or the pause phase.
The signal lamp or the green LED at the display flashes during the cycle test(s). In case of a single
cycle it will flash slowly (2-sec. on / 2-sec. off) and code “T1” will show at Twin-3 display. In a
multiple cycle test it will flash rapidly (0,2-sec. on / 0,2-sec. off) and code “T2” will show at Twin-3
display. Only the signal lamp will light continuously for 2 minutes in the end of each failed cycle
test. After the pump has been disabled due to a number failed cycles in succession the display will
show the initial cause by means of an fault code (see paragraph 4.6.4). This code can also be
visualized by the signal lamp (see paragraph 4.6.3).
Errors that occured during the test cycles are not stored in the control unit records.
NOTE
When the system is already performing a pumping phase, the system will not respond when the
test push-button or switch-button is pushed.

ATTENTION
Only use the cycle test if necessary. Every time a cycles test is performed, grease is added to the
grease points. This is at the expense of the grease volume and can lead to excessive greasing of
the grease points.
