DIAGNOSTIC EVALUATION

The first step in troubleshooting of this system or performing annual maintenance
will require the technician to open the controller door. With the power off to the
controller, the technician shall look over the controller circuit, and repair or replace
any apparent problems, such as loose wire connections, or corroded terminations.
After the initial visual checks have been completed, restore power to the controller
and pull out on the plunger of the cabinet safety switch (CSS), which is located at the
lower right edge of the enclosure. Observe at this time the LEDs located on PCB #1,
and PCB #2. Determine, by observation of these LED indicators, if the controller is
performing in normal operation.
LEDs on PCB #1 are numbered from top to bottom, 1-9. LEDs on PCB #2 are
numbered from top to bottom, D14 - D16. The following chart will indicate normal
LED operation.
