Modules
Turn controller power off before servicing
controls. This is to ensure safety and prevent damage
to the controller.

is indicated by

If there is no input power, check fuses. If fuse is bad, check
for shorted secondary of transformer, or for bad module.
Green LED: (On a

connectors. The other green LED on the
module indicates external communications, when used.)
The green LED should always be blinking
on; it indicates that the modules are communicating
properly.
