Why is the ERROR/ALARM LED on my NAiS FP0-C32T ON?

D
Duane SanchezAug 9, 2025
The ERROR/ALARM LED might be on for several reasons: * The system watchdog timer may have been activated, stopping FP0 operation. To resolve this, set the mode switch from RUN to PROG. and cycle the power OFF and then ON. * The program execution time might be too long. Review your program for instructions like JP or LOOP that could prevent a scan from finishing. * Interrupt instructions might be executed in succession. * You can also try setting the mode switch from PROG. to RUN.

What to do if the ERROR/ALARM LED is blinking on my NAiS FP0-C32T?

C
Charles JonesAug 18, 2025
If the ERROR/ALARM LED is blinking, it indicates a self-diagnostic error or a syntax error in the program. Here's what you can do: * Check the error code using the programming tool. * If there's a syntax error, switch to PROG. mode and clear the error. You can also execute a total-check function to pinpoint the syntax error's location. * For self-diagnostic errors other than syntax errors, use the programming tool in PROG. mode to clear the error. * In PROG. mode, turning the power OFF and then ON again can clear the error, but note that this will erase the operation memory (except hold type data). * Alternatively, you can clear the error by executing a self-diagnostic error set instruction F148 (ERR).

How to troubleshoot if all LEDs are OFF on NAiS Controller?

B
brookspatriciaAug 28, 2025
If all LEDs are OFF on your NAiS Controller, try the following: * Check the power supply wiring. * Ensure the power supplied to the FP0 control unit is within the rated range. * If the FP0 control unit shares its power supply with other devices, disconnect their power supply wiring. * Consider using a separate power supply for other devices or increasing the capacity of the current power supply.
