GREEN LEDs: When the SPD is securely connected and operating properly, the GREEN LEDs,
under the heading "PHASE INDICATORS", will be illuminated. No other indicator should be
illuminated if the unit is operating normally.
RED LED: If a problem develops with the internal monitoring circuitry or, in the unlikely event
that there should be a loss or reduction in the protection elements, the RED LED over the words
"SYSTEM FAULT" will illuminate.
YELLOW LED: If the Yellow LED illuminates, at any time, there could be a hazardous system
wiring fault. The YELLOW LED does not indicate a suppressor failure; however, it does signal
that there maybe dangerous Neutral to Ground Voltages present. Consult with a qualified
electrician to verify the integrity of the installation's wiring. (Not present on Delta Configurations.)
AUDIBLE ALARM: The Alarm will sound if protection should be lost on either the L-N or L-G
Modes. Control of the Alarm is managed with a switch located on the front panel next to the
Alarm. The switch has three (3) settings: Up (momentary only) for testing, which will sound the
alarm. Center, this is the Disable position and turns the Alarm off. Down, this Enables the Alarm
and sets it for constant monitoring.
STATUS INDICATORS
COUNTER: The Surge Counter will show the number of transient events that the suppressor
encounters. Control of the Surge Counter is managed with a switch located to the left of the count-
er display. The switch has three (3) settings: Up, (momentary only) for RESET. Center, this is the
ENABLE position and turns the Counter on and sets it for constant monitoring. Down, (momen-
tary only) this tests the Counter and will increase the count by 1 increment each time it is activated.
TROUBLE SHOOTING GUIDE
There is little or no trouble shooting required for this Series of products. However, there are
situations where there could arise a scenario where the Front Panel Diagnostics does not operate
as intended. In such a case follow these directions...
PROBLEM:
No Front Panel Diagnostics or improper operation:
Ensure that SPD unit is properly connected to the AC Service Panel and that all connections
are secure.
Confirm that the breaker in the AC supply panel is in the ON position.
If problem still persists: TURN OFF BREAKER, open the SPD door and verify that all VISI-
BLE cable connections are properly secured, no loose wires. This is especially critical for the con-
nectors on the Sensor Cable as they interface with the SG modules. When the SG module is prop-
erly connected the 2 Green LEDs should be illuminated and the center Yellow LED (not applica-
ble on Delta Units) should not. DO NOT attempt to trouble shoot inside individual SG Modules.
In the unlikely event that these measures have failed to correct the problem contact your dealer or
the factory for additional information.
