The guard is locked closed until the solenoid is energized. The solenoid can only be energized when the
auxiliary contacts (A) of contactors K1 and K2 are closed.
When the lock release button is pushed the locking mechanism is released and the switch contacts 11-12 and
21-22 are opened. These contacts are in series with contactor coils of K1 and K2 and will prevent re-start whilst
the guard is open.
If after pressing the Stop button either contactor K1 or K2 stays closed the motor will stop but the solenoid
cannot be energized or the guard opened.
LED 1 provides visual indication of solenoid power applied.
LED 2 provides visual indication of guard locked and machine able to start.
System is shown with machine stopped, guard closed and locked, and the solenoid able to be energised.
Application Example: Dual Channel non monitored.
The above system can be enhanced by alternatively connecting the switch
circuits 11-12 and 21-22 to an SCR-3 Safety Relay to monitor for wiring short
circuits.
This provides Dual Channel monitoring and a check of the contactor feedback
circuits through the auxiliary contacts (A) of K1 and K2.
The SCR-3 monitors the switch and the contactors K1 and K2 and provides it’s
own self-monitoring via force guided internal relays.
System is shown with machine stopped, guard closed and locked, and the
solenoid able to be energised.
Application Example: Dual Channel monitored.
