VCAUTION

CONDUCTING DIELECTRIC AND/OR

HI-POTENTIAL TESTING WILL CAUSE

INTERNAL DAMAGE TO TPS3 UNIT.

Do not perform dielectric or high potential

tests with the TPS3 unit installed.

SPDs require minimal maintenance. Periodic inspection of diagnostic LED indicators ensures proper operation. Clean SPD as appropriate.

Troubleshooting & Service

Please contact TPS Technical Support at 1.888.333.3545 for service related issues.

Quality SPDs are designed and tested to withstand severe duty. However, there are various electrical anomalies against which SPDs cannot protect. These are generally Sustained Overvoltages also known as Temporary Overvoltages (TOVs). In this context, Sustained Overvoltages may be only a few cycles. Failed SPDs tend to be symptoms, not root causes. There may be larger issues at play. Regardless of cause, SPDs attempt to protect their load until failure.

Bonding or reference to ground problems are the root cause of many SPD problems. If the SPD shows problems on startup, there is reasonable chance of bonding/grounding/misapplication issue. Such problems permanently damage the SPD. If not corrected, SPD problems will reoccur.

Tip: Visually confirm N-G bonding. Be aware that a voltmeter measuring N-G can be misleading. For example, N-G voltage could read 0V because neutral and ground are at the same potential purely by happenstance, not because they are bonded. Visually confirm bonding.

Tip: Experience indicates that regulation-challenged generators can cause Sustained Overvoltages, as well as ungrounded generators, and/or usual load transfer systems.

Abnormal N-G Voltage Indicators

This SPD include N-G voltage indicators. If the SPD detects excessive N-G voltage, the Red Service LED will blink and the Audible Alarm will cycle. This condition requires immediate attention as the SPD will fail.

VDANGER

Hazardous voltage.

Will cause death or serious injury.

Keep Out.

Qualified personnel only.

Disconnect and lock off all power before working on this equipment.

Incorrectly bonded distribution systems damage SPDs. If the XO or N-G bonding jumper is not installed, the electrical system has no reference to ground. It becomes an ungrounded system. Please see previous section regarding SPDs on ungrounded systems. Such systems are known to eventually produce abnormally high L-G voltages. SPDs will attempt to chase this system-level overvoltage abnormality until the SPD fails. This effect is accelerated on Wye systems where SPDs are designed for grounded systems. (SPDs for ungrounded systems generally have higher MCOV to allow for L-G voltage fluctuations.) Failures of this nature are not defects in the SPDs workmanship or material. This is an installation error and is not covered by warranty.

A differential voltage circuit monitors neutral to ground voltage. When N-G voltage becomes excessive, an amplifier energizes a resistor. Eventually, that resistor will overheat and cause thermally sensitive shrink wrap to shrink around the resistor. This does not occur on transient or instantaneous N-G overvoltages. When the SPD is deenergized, the shrink wrap covered resistor can be accessed by qualified personnel under the display plate cover.

Module Replacement & Service

The module is field replaceable. Service should only be performed by qualified persons. Deenergize SPD, confirm with appropriate measurement equipment and discharge internal capacitance to ground. Mark locations and carefully disconnect diagnostic cables, contacts, connecting conductors, etc. Unbolt module from backplane. Reinstall in reverse.

There are no user serviceable parts inside the module. Disassembly is not permitted.

Modules may be returned to the factory for factory service, qualification and return. Please contact factory at 1.888.333.3545 for assistance.
