RUN (green) indicator is on to show normal operation of the 1785-BEM
module.
FLT (red) indicator is on when a hardware fault is detected in the
1785-BEM module.
Note that these indicators light at power up or when a hardware fault
occurs in the 1785-BEM module.
ATTENTION: If the RUN indicator is blinking on the
secondary 1785-BEM module, it means that there is a switch
setting error. Note that switches of switch assembly SW2 must
be in the same position in both 1785-BEM modules. (If the
blinking RUN indicator goes unnoticed, it could prevent a
switchover.)
