Fault Variables

1. Remove all axis and DIM modules.

2. Plug the terminator into the system module. If the system module is

OK (system LED flashing red/green), go to step 3. If not (system
LED solid red) go to step 4.

3. Plug in each axis and DIM module one at a time, re-attaching the ter-

minator after each module is added. See which module causes the
system to fail (system LED solid red).

Note: If no module fails, combine the axis modules in different order,

until one fails.

4. Return the malfunctioning module to the manufacturer for repair.
