Follow this procedure:
1. Remove load from the Safety Lock: Run the drive opposite to the load
direction. The drive's power must correspond to the weight of the load.
2. Apply the operating pressure to pressure port L.
ð
Signal 1 “load secured” is no longer active.
ð
Signal 2 “clamping released” is displayed.
3. Relieve the pressure at pressure port L.
ð
Signal 2 “clamping released” is no longer active.
ð
Signal 1 “load secured” is displayed.
Cross-check the two signals! The signals must not occur simultaneously.
Brief overlap times during switching are admissible. Check the correct pro-
cessing of signals in the machine controller too.
If the signals from the proximity switches are not unambiguous, the reason
might be an incorrect depth setting, see accompanying adjustment instruc-
tions for proximity switches. They also contain details of the proximity switch
holder type as well as all further information on assembly and adjustment.
If malfunctions occur, contact SITEMA. We will be glad to help.
