125, 24 V, time-controlled
Revision: 01 1000088471 en-23
7 Output signals – Time control
The lubricator operates in time control mode as a time-based and cycle-controlled lubrication
system according to the values set in the
PRO menu.
7.1 Connection assignment – Time control
PIN Assignment Color
1 +24 V DC Brown
2 Not assigned White
3 Ground (GND) Blue
4 Output signal Black
Type: M12x1 plug socket; 4-pin, A-coded
Tbl - 14 PIN assignment – Time control
The lubricator can be fully shut down in time-control mode by switching off the supply voltage.
The settings made are not lost. The time, starting at switch off until the next scheduled lubrication
cycle is automatically saved by the lubricator in the integrated microelectronics. After the power
supply is reconnected, the lubricator carries out an automatic self-check and continues to operate
according to the set values.
i
After a longer standstill of the lubricator, manual triggering of a lubrication pulse is
recommended (see chapter 6.7 "Triggering single lubrication processes").
i
The output signal at PIN 4 can be picked up for further processing (e.g. indicator light or
external control system). The maximum admissible output current of I
max
< 20 mA must not be
exceeded. No inductive load (e.g. relay) may be connected!
