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 perma
-
nently 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 swit-
ched 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 prin-
ted circuit board (Fig. 14).
Signal lamp
• The signal lamp or the LED Figure 9 indicates the operating
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”.
