Siemens Surge Protective Device TPS3 12 - Manual (Page 15)

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 on-board
both modules.
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 inter-module diagnostic wiring. An illuminated red LED
indicates the damaged module.
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.)
