With a 10K Ohm resistor wired across the controller input (at the controller) the supervised input reads trouble with the door switch in either the closed or open position.
- Supervised Input
- IO Modules
- 10K Ohm resistor
The input voltage selector switch was set to 5 volts instead of 10 volts.
Changed the voltage selector switch from 5 to 10 volts and power cycled the IO module.
