5.2 Test run
When first commissioning the VOC, it is recommended that a test run without a workpiece is first
performed for the entire system. Liquid is sucked in to check that the system sensors and actuators are
functioning and that the signals are received and correctly interpreted by the overall machine control unit
(BAZ).
Step
Action
Impact
S 1
Connect the VOC to the overall machine via
the two multi-pole plugs
S 2
Connect the compressed air, supply hose
and feedback hose to the VOC
- The pressure regulator, item [9], must display 4 bar
- The VOC is now ready
S 3
Switch on the VOC from the overall machine - Valves 1V1 and 2V1 close
- Vacuum switch 1Z2, item [11], displays the value
-0.00
S 4
Start the vacuum generator from the overall
machine
- Storage tank is evacuated
- The vacuum value is shown by the display, item [14]
S 5
Evacuate the clamping device, incl. the
liquid part
(no workpiece and with slight leakage)
To test the function of the fill level limit switches
- Valve 1V1 closes and valve 1V2 opens
- Machining release from -600 mbar
- Vacuum value for machining release is displayed by
vacuum switch 1Z2, item [11]
- Storage tank fills with liquid
S 6
The liquid feedback starts automatically
- Liquid is fed back in a targeted manner
S 7
Critical fill level reached
- Liquid level rises despite feedback
- Machining stops in the overall machine and the liquid
supply ceases
- The vacuum generator continues to run
S 8
Liquid feedback
- Liquid continues to be fed back until liquid sensor
2Z1, item [12], is automatically reset
S 9
Reset liquid sensor 2Z1
- Release machine once again (el. signal)
S 10
Liquid is sucked in
- Storage tank fills
S 11
EMERGENCY STOP
- The EMERGENCY STOP is defined by the machine
manufacturer
