Troubleshooting Procedure

Cabinet Alarm
1. Locate the Galaxy controller. When a trouble condition exists, the red alarm on the top of the cabinet will be
illuminated and the display screen on the controller will typically have LED's illuminated. See Figure 12-1.

2. Determine the system status. For most problems, one or more alarm and status LEDs will be illuminated. Depending
on the controller type, the following will be displayed:
• system voltage
• system current
• system mode
• system number of alarm/warnings
If the screen is blank, but alarm and status LEDs are illuminated, call technical support. If the entire
panel is blank, check the controller fuses. Verify that the controller is getting power. If not, replace
fuse. If the display is still blank, call technical support.
3. To view the Alarms Menu: If the default screen appears normal, press the MENU button. The main menu appears
with "Alarms" blinking. Press ENTER to obtain the Alarms menu. Additional data appears that will help to identify the
problem.
