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.)
