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 cm
³
).
Connector PIN assignment M 12 x 1
PIN 1: input v20...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.
