can be assembled, with other parts, to a complete machine without affecting the safety and health of
humans.
The housing of Lubricus should not be exposed to direct sunlight and/or radiant heat preventing the
formation of condensation.
Electrical connection
•Have the electric power supply connected only by a trained electrician!
•Connection and wiring of the electric components should be done by an expert trained in this field.
•Check the voltage details with the existing power supply voltage!
Maintenance /repair
Disconnect the voltage feed, before starting with maintenance or repair.
Maintenance and repair work may only be done with the system shut down.
Check the surface temperature of Lubricus Lubrication System, due to danger of burning by radiant heat.
Always wear heat-resistance gloves! Protect the system from activation during maintenance and repair work!

Function/Principle
When you activate Lubricus, Type D, the piston pump starts to work and pump the lubricant in small quantities to the outlets.
The integrated microprocessor controls the function. Communication with the machine controller is necessary. Delivery rates
and time between the lubrication intervals can be individually set by pulse signals.
The Lubricus Lubrication System uses a four-pin socket to connect a M12X1 plug allowing communication with the machine
controller. An external 24 VDC power supply is used to switch ON and OFF (voltage of +20 ....up to +30 VDC, supplied to
PIN 1). When voltage is supplied the lubrication pump is in operating condition. If there are no errors (Pump OK) the input
voltage will be transferred to the output signal (PIN 4) indicating all is OK. Once the voltage supply to PIN 1 is stopped
(switched OFF), the pump rests and saves the current operating conditions in memory. When the pump is turned back on the
saved operating conditions will be continued. PIN 4 relays the operating condition.
Connector PIN assignment, connection to Lubicus, Type D
Output signal: in case of empty lubricant reservoir: PIN 4 generates an alternating high and low signal, switching with
0,5 Hz.
Pump function control: after receiving a correct pulse signal at PIN 2, the pump starts to work. During the function of the
pump (about 7s) the output signal at PIN 4 is switching from High (+ 20...30 VDC) to Low (0 V). By counting the signals of
the pump function control there is a possibility to estimate the delivered quantity of lubricant and the remaining quantity in the
lubricant reservoir (delivery rate per pulse signal =0,15 cm³).
Connector PIN assignment M 12 x 1
PIN 1: input voltage +20...30 VDC, color brown
PIN 2: activation of the individual pump outlets. color white
PIN 3: Ground (GND), color blue
PIN 4: Output Signal, color black
Details:
Peak current Imax (during pump operation) approx. 350 mA,
typically < 200 mA, Standby current (standby mode) < 20 mA
Output signal PIN 4: High (+20…30 VDC) = OK
Low = 0 V = Error (empty signal, over current)
The outlet signal, PIN4, can be charged with maximal
300mA.Warning: the exit is not short-circuit proof
A time delay fuse 1A is normally required.

Function: Extra dispensing cycle
a) De airing of pump: High signal on Pin 2 for 12 seconds: extra lubricant cycle will be started to each pump element
to exhaust air inclusions. Can be repeated a view times until all air is removed.
b) Prefilling of tubing:
After de airing the pump extra lubrication cycles can be used to prefill tubing or fill the supply tubes to the
lubrication point. High signal on Pin 2 for 12 seconds: extra lubricant will be supplied to outlet

Functional problems
Error messages / faults: The dedicated error message is given to PIN 4
E1: Empty lubricant reservoir
PIN 4 generates an alternating high and low signal, switching with 0,5 Hz.
Root cause: lubricant cartridge is empty.
The pump will stop!
Corrective action: replace cartridge.
Pump will continue to run as per active program
E2: Back pressure too high / over-current:
Output Signal = Low
Root cause: Back pressure was measured 3 x too high. The lubrication point could be clogged, the tube length could
be too long or the grease is too stiff or has hardened. The pump will stop!
Corrective action: Trace reason for high back pressure >70bar and correct it.
Switch unit „OFF“ and „On“ again. The error message will be reset to 0. The pump will start again as per
program in memory.
System error: Switch unit „OFF“ and „On“ again, Memory will not be erased.

Service: replacement of cartridge
Any further service is not necessary.
1. Observe the safety instructions. Switch off the pump: Display –report „OFF“
2. Take out ventilation locking (turn clock wise to OPEN)
3. Press the housing, turn left and remove it
4. Remove the empty cartridge.
5. Remove protection from the new cartridge
6. Lubricate O-Ring of the new cartridge slightly.
7. Place the cartridge on the inlet
8. Place the pump upright on flat surface. Reinstall the housing by
gently pressing while turning clockwise until hand tight.
9. Install the ventilation lock and close it (turn counter clockwise to CLOSE)
10. Pump will work again according to settings, error report will be deleted
