Operation
LED Status Indicators
The diagnostic display panel shows the status of the SPD module with
diagnostically controlled green/red LEDs. If a unit is operating correctly, all
the phase LEDs will be illuminated green. To test the integrity of the
diagnostics for each phase, push the button below the phase LEDs on the
diagnostic display panel. The green LED will turn red and the alarm will
sound, if the alarm is enabled. Releasing the test button will complete the
test; the red LED will turn green and the alarm will shut off.
If an inoperable condition occurs on any phase, the audible alarm sounds
and the corresponding phase LED on the diagnostic display panel is
illuminated red. This indicates that the device needs service by qualified
electrical personnel. The audible alarm can be silenced by pressing the
alarm enable/disable button. The alarm will silence and the green alarm
LED will not be lit. The red phase LED will continue to be illuminated until
the inoperative condition had been cleared.
On an SPD module (see Figure 9), if the left green LED is not lit, it indicates
a loss of suppression from line-to-ground for that phase. If the right green
LED is not lit, it indicates a loss of suppression from line-to-neutral for that
phase. If the diagnostic display has power and both green LEDs are not lit
the module should be replaced.
