Figure 11 - To acknowledge a fault
When the pushbutton is pressed briefly (< 1 second) the
fault is acknowledged, i.e. the lamp stops flashing and is
permanently lit.
Note: Any acknowledged fault remains stored even after the
driving switch or machine contact has been switched off.
Upon switching on again, the signal lamp flashes again in
accordance with the fault.
To Remedy to a Fault
* In the case of a malfunctioning, check the central
lubrication pump and the connected system for faults.
* Eliminate the cause of the fault.
* Switch on the pump again by triggering an additional
lubrication cycle. For this, press the pushbutton
>2
seconds.
·
When the fault is eliminated, the signal lamp will
extinguish
at the end of the lubrication cycle.
Important:
If there has been any fault, the pump will not
start automatically after the elimination of that fault. It must
be switched on, i.e. an additional lubrication cycle must be
triggered. See To trigger an additional lubrication cycle.
Note: It is also possible to acknowledge/reset a fault or
trigger an additional lubrication cycle by means of the
pushbutton on the printed circuit board (Fig. 14). For this,
press it < 1 second and > 2 seconds.
Condition: The
machine contact or driving switch must be switched on
.
To acknowledge a Fault
Functional check
Each time the machine contact (external contact) or the
driving switch is switched on, a functional check of the
drive motor and signal lamp takes place automatically.
During the functional check the motor is switched on for
0.1 second
(the stirring paddle slightly rotates) and the
signal lamp lights up for
2 seconds
.
If there is a fault, the signal lamp
flashes
. See Fault
Indication.
Note: LED display Figure 9 indicates the same operating
state as the signal lamp.

Pushbutton
(Fig. 11)
The following functions can be performed with the
pushbutton:
- triggering an additional lubrication cycle - Press
pushbutton for over 2 seconds (> 2 s)
- fault acknowledgement < 1 s
- in the case of a fault, switching on pump again by
pressing pushbutton (> 2 seconds)

Functions of the Pushbutton and Signal Lamp
Note: It is also possible to acknowledge any fault or to
trigger an additional lubrication cycle via pushbutton 4 of
the printed circuit board (Fig. 14).
Signal lamp
The signal lamp or the LED Figure 9 indicates the opera-
ting state of the centralized lubrication system.
The faults are indicated by different flashing frequencies
of the signal lamp or the LED Figure 9. See Fault
Indication.
