The 440R-S07279 control unit is a compact timing and stop motion detector interface module. By utilizing two independent inductive proximity inputs which monitor the movement of two metal parts of the machine (e.g., sprockets, cams or linkages), the control unit 440R-S07279 detects when hazardous motion has ceased. When the hazardous motion has stopped the unit will send a signal to unlock guard locking devices. 440R-S07279 has been developed to integrate guardlocking interlock switches on machines which have variable or unpredictable run down cycles.
A removable cover allows access to the DIP switches and potentiometer which control the timing. The on-delay may be adjusted between 0.1 seconds to 40 minutes, through a series of 4 broad time ranges. The final adjustment is made by a potentiometer. The Y1/Y2 terminals provide a check of contactors at machine power up. This is only relevant to certain special applications. For normal use these terminals should be linked. After all motion has ceased, the N.O. safety on contacts close, which may be used to energize electrically operated solenoid locking guard switches. In addition the N.C. contacts open to indicate the unit's status. LED indication in the unit displays power, timer on, and outputs.
