2628

UnclassifiedGeneral

What This Code Means

Discrete input #9 fault is active

Possible Causes

  • •Condition for which Discrete Input #9 is configured is active
  • •Discrete Input #9 active state selection parameter is configured incorrectly
  • •Incorrectly wired; or open circuit or short circuit in the wiring

Suggested Actions

  1. 1Check the condition for which "Discrete Input #9" has been configured for. After the issue is resolved, press the Reset button on the Operator Panel in order to clear the fault, if the fault does not clear go to next step.
  2. 2Check the wiring at J4-1 (switch input 1) and J4-2 (reference input) for an open circuit, short circuit, or a miswired condition.
  3. 3With InPower or through the Operator Panel check the switch input setting (active closed or active open) for Discrete Input #9. Ensure that the switch input setting is correctly set. If "Discrete Input #9 Sensor Type" parameter is set to active low, an active high will invert the logic, causing this fault code to go active.
