DIAGNOSTIC INDICATION
Phase indicator LEDs (Green)
Each phase is equipped with a green LED. Should
complete loss of surge protection occur on each
phase, the green LED will extinguish and the red
service LED will flash. Every suppression element
is monitored. Note that the green LED indicators
will drop out due to loss of power or severe under
voltage.
Service LED (Red)
Flashes in the event of a problem. The red service
LED is slaved to the green LEDs via logic and will
illuminate when any green LED extinguishes.
Audible Alarm Option
If equipped with optional Dry Contact and Audible
Alarm, these options are slaved via logic to the
green LEDs. In the event of a problem, the Dry
Contacts will change state and the Audible Alarm
will sound. The Audible Alarm may be silenced by
deenergizing the SPD.

Diagnostic Display Operation
All indicators and controls are located on the
Diagnostic Display. Each phase features a green
LED indicator. Green LEDs indicate correct
operation. If an inoperative condition were to
occur, the built-in Audible Alarm will sound and
the red service LED will illuminate. This indicates
that the unit needs evaluation by a qualified
electrician or technician. Until a qualified person
evaluates the unit, press Silence to silence the
alarm. (The LED above Alarm Silence illuminates
when the alarm is deactivated. Normal operation
occurs with the Alarm Silence LED extinguished.)
