7.5.3 Mating connector assignment: Filling level/temperature sensor, filter
contamination sensors ("Basic" configuration)
For status monitoring, the hydraulic power unit is equipped with the following
sensors:
• Filling level and temperature sensor with two switching points each:
Pin 1: 24 VDC supply
Pin 2: 24 VDC output for filling level warning (normally open contact)
Warning in case of 24 VDC
Pin 3: 24 VDC output for filling level or thermal shutdown (normally closed contact)
Pin 4: 24 VDC output for temperature warning (normally open contact)
• Filter contamination sensor 75 %
Pin 1: 24 VDC supply
Pin 2: 24 VDC output for filter contamination warning (normally closed contact)
• Filter contamination sensor 100 %
Pin 1: 24 VDC supply
Pin 3: 24 VDC output for filter contamination shutdown (normally closed contact)
In "Basic" configuration, the three sensors must be wired to the superior machine
control system for evaluation.
In case of shutdown, the enable signal of the hydraulic power unit must be canceled.
In the "Advanced" and "Premium" configuration, the warning and shutdown signals
are internally wired and evaluated via port 16X1.
For information on the meaning of the LED signals, refer to fig. 3 "Name plate"
and chapter 10.3 "Warning devices".
The status is visualized via the flashing sequence and color of the integrated LED
strip, see name plate fig. 3.
