Troubleshooting Procedure
Purpose
The troubleshooting procedure described below is used when a trouble condition has
been identified and a technician has been dispatched to the system as a first step in
diagnosing and correcting the problem.
For all trouble conditions, proceed as follows:
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.
Figure 15-1: Location of cabinet alarm indicators
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.
