DANGER

No personal protection!

The KL2692 may only be used for cycle monitoring with the purpose of preventing machine damage!

The KL2692 must not be used for cycle monitoring for personal protection under any circumstances!

The KL2692 must not be used for protection functions such as emergency stop, access protection, secure room monitoring, robot range monitoring, press safety valves etc.!

Switching off the voltage for the power contacts

The NO contacts of the KL2692 control a contactor that switches the supply voltage (24 V) for the power contacts..

Function

  1. Monitoring can be enabled via push button S1 (negative edge) when the watchdog is triggered. The KL2692 relays are switched on, and contactor K1 switches on the supply voltage (24 V) for the power contacts.
  2. If the watchdog is not triggered over the watchdog time specified in register R35, the KL2692 relays are de-energized and contactor K1 switches off the supply voltage for the power contacts.
  3. If the watchdog is triggered again, monitoring has to be re-enabled via push button S1, so that the KL2692 relays switch on again!
  4. NC contacts S2 and S3 can be used for manually switching off contactor K1 and therefore the supply voltage for the power contacts.
