Redundant Power Supply Sequencer Module (RPSSM)
terminal block connectors TB1, TB2, and TB3 to the RPSSM until you
have installed, wired, and configured the CPU module.

Setting Jumpers
Depending upon how you are using the RPSSM, you may have to change
one or more jumpers from their factor default positions. See Table P-1 for
a list of the jumpers and their functions; see Figure P-3 for jumper
locations.
Table P-1. RPSSM Jumpers
Jumper Position Description
JP1 1-2 Enables the watchdog circuitry.
This is the default. Watchdog wiring is discussed later in this document.
2-3 Disables the watchdog circuitry.
JP2 1-2 Sets the RPSSM as always the on-line unit.
This is the default. Use this setting if the RPSSM is not installed in a redundant system.
2-3 Specifies that the RPSSM is part of a redundant system.
Choose this position if the RPSSM is installed:
In a ControlWave Redundant Controller or
In a ControlWave Controller that is part of a redundant pair or
In a ControlWave I/O Expansion Rack that is part of a redundant pair.
JP3 1-2 Enables the 12V monitor.
This is the default. When enabled, the RPSSM reports a failure when voltage falls
below 12V and lights the PWR Down LED to indicate the failure.
P-2 Installation and Use Revised Nov-2010
