procedure.
1) Apply power to the controller system.
2) Download your program, which contains the RTD/resistance module
configuration settings, to the controller.
3) Put the controller in Run mode. During a normal start-up, the module status
LED turns on.
Note: If the module status LED does not turn on, cycle power. If the condition
persists, contact your local distributor or Spectrum Controls for assistance.
