10.5. Special accessory malfunction indicator at pressure relief valve:

The pump elements for the electric pump EP-1 can be
equipped with a visual malfunction indicator. If a
malfunction occurs in the central lubrication system
and the operating pressure increases above 280 bar,
EN
the red control pin becomes visible. The grease
escaping through the pressure relief valve is returned
into the reservoir. Once the malfunction is remedied,
the red control pin must be pushed back.

11. Function of the control units:

11.1. Control unit BEKA-troniX1 and EP-tronic:

11.1.1.

Operating mode time control and rotary control

The control unit BEKA-troniX1 and EP-tronic operate lubrication cycle dependant. The
lubrication cycle is divided into lubrication time and cycle time.
Diagram of a lubrication cycle:
Independent on the adjusted program, the green and the red LED in the inspection window of
the control unit glow for approx. 1,5 sec. after switching on the ignition, thus signalling the
function of the control unit (turn-on check).
With each initial activation of the pump starts a lubrication process. The green LED in the
inspection window of the control glows during the whole lubrication process.
The control unit has a data memory. It serves, among other things, for saving the run-down
times. When the ignition is interrupted, the remaining lubrication- or cycle time is saved. Once
the ignition is switched on again, are the times read in the memory and the procedure is
continued where it has been interrupted before.
