APC PMP3XS-B 사용자 설명서

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.

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.

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.
