the performance of the SPD and are not required to be connected for the SPD to function as
intended. (See page 10 for Alarm Contact details)

TEST / ENABLE / DISABLE SWITCH
Enable Position - This is the normal position for the tri-position switch. In the Enable
position, the Audible Alarm will sound in the event of a SPD failure mode.
Disable Position – This position will silence the Audible Alarm if desired. The Disable
switch will not disable or disconnect the SPD from the electrical power system.
Test Position – The Test switch provides a quick diagnostic status of the Audible Alarm,
Alarm Status Indicator and Remote Alarm Contacts. When pressed, the Audible Alarm
will sound, the Alarm Lamp will illuminate, and the Remote Contacts will change state.
The “Test” position is momentary. Once pressed, the switch will automatically reset to
the “Enable Position” upon release.
5.
SURGE COUNTER LCD
The Surge Counter will sense and record transient surge events that have been mitigated by
the SPD. The counter has been designed to detect transients that exceed the peak sine wave
by more than 70%. If desired, the Surge Counter Display can be reset to zero at any time by
pressing the reset button located on the LCD display.
MAINTENANCE:
GE does not provide a specific schedule for preventative maintenance as conditions will vary
based on location and the environmental factors presented at each installation site. However,
periodic inspections should be scheduled to verify that the SPD does not indicate a failure mode.
Inspections should also be made to check the integrity of the electrical supply connections to the
SPD to ensure continued reliable performance.
SERVICING / TROUBLESHOOTING:
The GE TR7000 ETP Series SPD contains no user serviceable parts and requires no calibration.
The rugged design of the SPD should provide many years of service.
Should a condition occur that results in premature failure of the GE TR7000 SPD, the integral SPD
suppression thermal fusing will safely interrupt current flow through the SPD without disrupting
power to the protected equipment. This will remove the SPD from the power system and the
load equipment will remain unprotected from subsequent surge activity until the SPD is
replaced.
If a change in operational status/alarm indication occurs, a qualified (licensed) electrician should
inspect the electrical system to verify electrical system integrity. If the SPD remains in alarm
after system inspection/corrections have been made, the SPD should be replaced. For further
assistance, contact your local sales representative or call GE Power Quality at 1-800-637-1738.
WARNING
IN THE EVENT OF AN SPD ALARM CONDITION, DO NOT ATTEMPT
TO DIS-ASSEMBLE THE SPD TO REPLACE FUSING OR OTHER
COMPONENTS. THE SPD CONTAINS THERMALLY PROTECTED
MOV’S THAT WILL ONLY OPEN WHEN THE SPD HAS FAILED IN A
NON-SERVICEABLE CONDITION. THE ENTIRE SPD MUST BE
REPLACED.
