Multiple greasing cycle test
In order to provide additional grease to all grease points i.e. after cleaning the vehicle or to purge
the system, perform a multiple greasing cycle as follows:
1.
With the test push-button at pump:
a.
Switch ignition ON;
b.
Push the test-button at pump for more then 6 seconds.
The system will operate a multiple greasing cycle.
During the operation the green LED at Twin-3 display will flash quickly (0,2-sec. on / 0,2-
sec. off).
A code “T2” and a running-decimal-dot will be indicating its pump, pressure retaining
and pressure decrease phase at Twin-3 display;
c.
The multiple greasing cycle can be finished by simply switching ignition OFF.
2.
With the switch-button at Twin-3 display:
a.
Switch ignition ON;
b.
Push the switch-button at least for 5 seconds.
Accordingly, the 3-digit display starts flashing;
c.
Push the switch-button repeatedly until code “T2” shows;
d.
Leave the code “T2” flashing until the code comes on.
The system will operate a multiple greasing cycle. (See also next alinea).
During the operation the green LED at Twin-3 display will flash quickly (0,2-sec. on / 0,2-
sec. off).
A code “T2” and a running-decimal-dot will be indicating its pump, pressure retaining
and pressure decrease phase at Twin-3 display;
e.
The multiple greasing cycle can be finished by simply switching ignition OFF.
The system will start a pumping phase. After pumping phase A, pressure retaining phase A and
pressure decrease phase A are ended, pumping phase B is started immediately, then again A, then
B, etc. The pause phases are skipped entirely every time.
When the ignition is switched ON again the program will always begin with the pause phase of the
pumping phase that has just been interrupted.
ATTENTION
It is also possible to skip the pressure retaining phase and pressure decrease phase during the
multiple cycles test, by activating the "enable fast multiple test" option with an Uni- or PC-GINA
(see parameter menu).
Please be aware that when activated at low temperatures, the output of the metering units in the
end of the system might get reduced to 0, due to these missing phases.
