Remote control
This step involves correctly placing the prepared pump assembly in the container so that it only has to be connected. You must use the shovel plate, the pump and the lid whose sizes are adapted to the chosen container. For more information on the sizes available, consult your MEMOLUB® distributor.
Before placing the pump in the container, you must check the following points otherwise the shovel plate may not work properly.

The DS pump's work cycle is created by the alternating movement of the piston.
The piston's movements are caused by the air throughput, controlled by the timer in the black box. A work cycle is composed of two work phases (T1 and T2):
T1 (piston descending phase): internal transfer of the lubricant towards the expulsion chamber.
T2 (piston ascending phase): simultaneous aspiration and expulsion of the lubricant.
The MEMOLUB® DS CONTROL UNIT Unit is a simple electronic system for managing the expulsion of the lubricant. A MEMOLUB® DS CONTROL UNIT can manage several pumps. Note that it is possible to connect a visual feedback via a distributor system with an optional on-off switch. The control unit comes in 2 versions: 24VDC or 220 VAC 50Hz.
The electronic box is composed of a circuit card and a solenoid. The solenoid powers the pump's "IN1" and "IN2" inputs alternately via two pipes corresponding to the two cycles of the pump.
The output is settable from 2.25cc/3.375cc / 4.5cc and can develop a power of 120 bars with an air pressure of 6 bars thanks to a ratio of the latter of 1:20.

Screw an M 1/8”G stopper onto air output 1 (AIR OUT T1) using a an Allen key
Screw an M 1/8”G stopper onto air output 2 (AIR OUT T2) using a an Allen key
Screw the elbow adapter M 1/2ʺG to the pump's lubricant output
On the top output (2), put the conical M 1/4ʺG / straight M 1/4ʺG adapter (please leave the straight M 1/4ʺG of this adapter free for the connection with the high-pressure hose).
Valve in position, greasing mode (horizontally).
Check the components have not been damaged due to transport or handling.
Check the quality of the plastic bag containing the lubricant. This must not have any air bulges at the top of the container.
Yes, the DS pump can be tested at any time by using its build in "check function". This process consists of operating a pump cycle manually, i.e. the two cycles (T1/T2) of the pump by shunting electronic timer.
If you don't have the manual "check function" remote control, this test can be done by turning the electronic box's power off and on.
Flip the red button of the manual "Check Function" command alternately with a time lapse of 10sec between each test.
After every use of the "check function", please remove the remote control so the electronic box can switch to its operating mode.
The container is empty when there is no more pressure variation on the pump's output pressure gauge. (NB, this could also be a priming problem).
A level gauge (see optional items) also provides visual information on the remaining lubricant volume. If the container is empty, follow these steps:
If the pressure gauge at the pump output indicates zero pressure the pump can be un-primed. In this case, follow these steps:
If the pump does not re-prime after the above steps, contact your MEMOLUB® dealer.
