Display Replacement
The display is field replaceable. 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 display and replace. Reinstall in reverse.
Note that a sealing gasket between the display and the enclosure is a key component ensuring weather resistance. Replace the gasket whenever the display is removed.
TPS3 15 Series with two modules
The TPS3 15 features two redundant modules. One diagnostic display monitors both modules simultaneously via the parallel wire connections between the modules. These connectors plug in to each module, transfering information to internal logic
If an inoperate condition were to occur, the diagnostic display will indicate a problem via red Service LED, audible alarm and dry contact change. Operation is identical to TPS3 12 series.
Each TPS3 15 module includes a red LED above the phase connection tabs, near the
Extra Information: Should one damaged module be removed, the SPD can still function correctly with one module. If the diagnostic display cable was connected to the removed module, reconnect the cable to the other module’s quick release connector. The diagnostic display will function correctly. (TPS3 15’s with Type 4X or 4S enclosures have the diagnostic display mounted inside the enclosure on the right side module. If this module is removed, the diagnostic display may be moved to the other module. Remove the display’s four screws, the display and appropriate internal ribbon cable. Remove blank cover from the remaining module and reassemble in reverse order.)
