Possible Causes

• •Aux 102 1 Discrete Input #2 Active State Selection Parameter is configured incorrectly
• •Aux 102 1 Discrete Input #2 active state selection parameter is configured incorrectly
• •Condition for which Discrete Input #2 is configured for is active
• •Condition for which Discrete Input #2 is configured is active
• •Damaged or contaminated switch/harness connector pins (bent, broken, pushed back, expanded, moisture, corrosion, missing/damaged seals, dirt/debris)
• •Discrete Input #2 active state selection parameter is configured incorrectly (e.g., active close vs active open logic inverted)
• •Faulty switch connector or wiring
• •Faulty switch connector(s) (inadequate connection, short circuit, open circuit, wiring mismatch)
• •Faulty switch connector(s) (inadequate connection, short circuit, open circuit, wiring mismatch, pin damage, moisture/corrosion, missing/damaged seals, or debris)
• •Faulty switch unit
• •Faulty switch unit (defects, physical damage, shorted or open circuit)
• •Faulty switch unit (defects, physical damage, shorted, or open circuit)

Suggested Actions

1. 1Check switch connector plug for adequate connection, short circuit, open circuit, or wiring mismatch
2. 2Check switch unit plug connection for adequate connection, short circuit, open circuit, or wiring mismatch
3. 3Check switch unit's connection at the plug for adequate connection, short circuit, open circuit, or wiring mismatch
4. 4Inspect switch and harness connector pins for bent, broken, pushed back, or expanded pins
5. 5Inspect switch and harness connector pins for bent, broken, pushed back, or expanded pins, moisture or corrosion, missing or damaged connector seals, and dirt or debris
6. 6Inspect switch and harness connector pins for bent, broken, pushed back, or expanded pins, moisture, corrosion, missing/damaged seals, or dirt and debris
7. 7Inspect switch and harness connectors for moisture, corrosion, missing/damaged connector seals, or dirt/debris
8. 8Measure switch resistance (< 10 ohms for closed; > 100 Kohms for open) and replace switch if reading incorrectly
9. 9Measure switch resistance (< 10 ohms for closed; > 100 Kohms for open) and replace the switch if reading incorrectly (shorted or open circuit)
10. 10Press the Reset button on the operator panel to clear the fault after resolving the issue
11. 11Verify and correct switch input setting (active closed or active open) using InPower service tool or operator panel under Setup > Aux 101 Setup
12. 12Verify and correct the switch input setting (active closed or active open) for Discrete Input #2 via InPower service tool or operator panel under Setup > Aux 101 Setup
13. 13Verify and correct the switch input setting (active closed or active open) using the InPower service tool or operator panel under Setup > Aux 101 Setup
14. 14Verify the condition for which Discrete Input #2 has been configured
15. 15Verify the condition for which Discrete Input #2 has been configured and press the Reset button on the operator panel after resolving the issue
16. 16Verify the condition for which Discrete Input #2 has been configured and resolve the underlying issue
17. 17Visually inspect switch for proper operation, intended range of movement, functionality, defects, or physical damage; replace switch unit if defects are found
18. 18Visually inspect switch for proper operation, range of movement, defects, or physical damage, and replace if necessary
19. 19Visually inspect the switch for proper operation, intended range of movement, defects, or physical damage, and replace if necessary
