Function of the central lubrication pump:

The central lubrication pump EP-1 or FKGGM-EP is designed for delivering lubricant up to NLGI
class 2. The agitator blade pushes the lubricant through a grease sieve to the intake section of
the pump element. The pump element is positively driven by an eccentric so that function is also
ensured at low temperatures. The output rate depends on the installed pump element (see page
20).

Without control unit:

At pumps without control unit can the lubrication cycle be controlled by an on-board controller, a
machine control or PLC.
9.2. With PE-120 V:
For trailers and semi-trailers, it is not possible to ensure a permanent current supply of the pump
or the control unit. Therefore is a central lubrication pump without control and with adjustable
pump elements installed into such vehicles. The pump gets its operating voltage via the brake
light and thus the pump always lubricates with each braking. The lubricant can be reduced with
the adjustable pump element (see adjustment of the pump element on page 21).

Special equipment of the central lubrication pump without control unit:

9.3.1. Grease level monitoring with plug-type connection M12x1 (Standard):
At the electrical pump EP-1 or FKGGM-EP can the
grease level be checked visually through the
transparent reservoir.
However, there is also the possibility to monitor the
grease level in the reservoir electronically. A capacitive
proximity switch is installed into the reservoir for this
purpose. This switch emits a signal as long as there is
sufficient grease in the reservoir. If the grease falls
below a certain level, the proximity switch stops this
signal.
The signal can be evaluated by an external control or
PLC. Evaluation should only be done after a period of
approx. 10 sec. If there is no signal for longer than 10
seconds, the reservoir is empty and the pump should
be switched off.
Not keeping to the period of 10 sec. can cause level errors although the
