Possible Causes

• •Aux 101 1 Analog Input #7 active state selection parameter is configured incorrectly
• •Condition for which Analog/Switch Input #7 is configured for is active
• •Faulty switch connector(s) (inadequate connection, short circuit, open circuit, or wiring mismatch at the switch connector end)
• •Faulty switch unit (physical defects, physical damage, shorted, or open circuit)

Suggested Actions

1. 1Check switch connection at the plug for an adequate connection, short circuit, open circuit, or wiring mismatch
2. 2Disconnect wiring harness and test resistance between switch output leads and base board input leads (should be < 10 ohms)
3. 3Measure switch resistance (< 10 ohms for closed; > 100 Kohms for open) and replace if reading incorrectly (shorted or open circuit)
4. 4Press the Reset button on the operator panel to clear the fault after resolving the condition
5. 5Test resistance from switch output leads to all other pins in harness connector (should be > 100k ohms)
6. 6Verify and adjust the switch input setting (active closed or active open) via InPower service tool or operator panel under Setup > Aux 101 Setup
7. 7Verify the condition for which Analog/Switch Input #7 has been configured
8. 8Visually inspect the switch for proper operation, intended range of movement, and physical damage/defects; replace switch unit if needed
