2. Check the SRM1’s LED indicator status. If the SRM1 is operating properly,
the PWR, RUN, SD, and RD indicators should all be lit, the COMM indicator
should flash, and all other indicators should be unlit. If the indicator status is
anything other than this, refer to 5-4 Error Processing.

different from those described in Explanation of Operations, check the pro-
gram and the I/O wiring.
Note For checking the program, refer to 5-6 Programming Errors and the Program-
ming Manual.
