6. Move the Mode Switch back to NORMAL.
7. The MCU will cycle through diagnostic testing. When the system is ready for
use, the error LED should be off, and the LED for the MCU Number (1-4) will be
lit. This should take less than two minutes.
If the LED for the MCU ID does not light, or if an MCU ID is duplicated, there is
most likely a problem with the IPC cabling. If the system displays an error refer
to 8.1 Troubleshoot Error Codes.
8. If you select a switch type that is not supported by the MCU type, the system will
alarm. The Error LED will flash along with Status LEDs 4 and 5. For example,
this alarm will display if you assign switch type NEC to an SCB-5XX –
Executone MCU.
If this alarm displays, use the table above to verify that your MCU type supports
the selected switch type. If you need to change the switch type, repeat steps 2
through 6.
