Circuit Breaker Reset—Model 494.33 DI/O Power Supply
The Model 494.33 DI/O Power Supply includes a circuit breaker that is built
into the power switch.
Important You should develop a circuit breaker reset procedure based
on a risk assessment for your system.
Reset procedure 1. If required, shut down system hydraulics.
2. Switch the Power switch on the front of the power supply to the off
position.
3. If required, check the controller input/output status to make sure that
they are set to a safe state.
4. Switch the Power switch on the front of the power supply to the on
position.
Switching the power switch off and then on resets the circuit breaker. If
the overcurrent condition still exists, the circuit breaker continues to
trip (remove power) each time it is reset.
Resetting the circuit breaker restores power to digital input and output
(DI/O) devices. Resetting the circuit breaker can result in unexpected
actuator movement and unexpected operation of DI/O devices.
Unexpected actuator movement and operation of DI/O devices can
result in injury to personnel or damage to the equipment.
Follow a circuit breaker reset procedure that is based on a risk assessment
that you performed for your site.
