Installation and Operation Manual 17
When power is applied to the SPD and one or more of the diagnostic display
panel LEDs are red, and one or more module LEDs are out, the module should
be replaced. Refer to “Maintenance and Troubleshooting” on page 19 for proper
troubleshooting procedures.
Audible Alarm Push the alarm enable/disable button to enable or disable the alarm (see
Figure 7). If the green alarm LED is lit the alarm is enabled. If the green alarm
LED is not lit the alarm is disabled.
Surge Counter The surge counter displays the number of transient voltage surges since the
counter was last reset. The counter is battery powered to retain memory in the
event of a power loss to the diagnostic display panel. To reset the surge counter
remove all power and press the small switch located inside the unit on the
underside of the diagnostic circuit board near the RJ45 connectors (also refer to
Figure 8). This will reset the counter to zero.
