Start Up, Operation, Troubleshooting, and
Debug Mode
This chapter provides start up, operation, and troubleshooting
information, as well as detailing the operation of the debug mode.
Start Up The following steps will assist you in the start up of your 1746-HSCE2
module.
1. Install the module in the chassis.
2. Wire the input and output devices.
3. Configure and program your SLC processor to operate with the
module.
4. Apply power to the SLC system and to the attached inputs and
outputs.
When power is applied to the SLC system, the processor and the
module run through a power up diagnostic sequence. After the
diagnostics are successfully completed, the SLC processor enters run
mode and normal operation begins.
If the SLC processor was in the program mode when power was
removed, it returns to the program mode when power is reapplied.
Place the SLC processor into run mode using an SLC programming
device or keyswitch.
Normal Operation During normal operation, the LEDs are illuminated as follows:
• The fault LED [FLT] is off.
• LEDs A1, A2, B1, B2, Z1, and Z2 illuminate, indicating the inputs
are energized.
• LEDs 1, 2, 3, and 4 illuminate, indicating the status of the
physical outputs.
• The run LED is on to indicate the module’s running status.
