Output short-circuit detection

¿Qué significa A0  H ?

A short-circuit has been detected on an output terminal. This indicates an abnormally low resistance path, likely causing excessive current flow, which can damage the module or connected components if not addressed promptly.

• Short-circuit in the output wiring between the module and the load.
• Internal short-circuit within the connected output load (e.g., actuator, solenoid).
• Damage to the output terminal itself, creating a short.

1. 1

   Identify and eliminate the short-circuit in the output wiring or connected load.

2. 2

   After recovery from the short-circuit, turn 'Alarm clear request' (Y11) on and off to clear the alarm.

3. 3

   Verify that 'Output short-circuit detection status' reads 0 (Normal) and 'Alarm flag' (X11) turns off after clearing.
