Electrical connections/Operating modes
RESTART (MANUAL OPERATION)
Î
Refer to “APPENDIX A1: SM - SMO MODELS WIRING SAMPLES - MANUAL MODE”, page 37.
Pin 10 has RESTART function. As a result of occupation of the protected area, OSSDs outputs will be
deactivated (OFF) (Manual mode - start/restart interlock enabled).
Î
To reactivate OSSDs press and release the N.O. RESTART pushbutton connected to 24VDC. Verify the
logical sequence: 0 → 1 → 0.
¾
The high level (24Vdc) time must be between 100 ms and 5 s.
Use in manual mode (start/restart interlock enabled) is mandatory in case the safety device
controls a gate to protect a dangerous area and a person, once crossed the gate, can stay
in the hazardous area without being detected (use as a ‘trip device’ according to IEC 61496).
The Restart command must be located outside the hazardous area, at a point where the
hazardous area and the entire working area concerned are clearly visible.
It must not be possible to reach the command from inside the hazardous area.
AUTOMATIC OPERATION
Î
“APPENDIX A2: SM - SMO MODELS WIRING SAMPLES - AUTOMATIC MODE”, page 39
In Automatic operating mode, the OSSD1 and OSSD2 safety outputs follow the status of the light curtain:
¾
with guarded area free, the outputs are ON.
¾
with guarded area occupied, the outputs are OFF.
If the SAFEGATE light curtain is used in AUTOMATIC mode, it will not be equipped with
a start/restart interlock circuit. In most applications, this safety function is mandatory.
Carefully evaluate the risks analysis of your own application.
