Redundant Processor Unit
Main Power Supply Module
GEK-84861B
March 1989
General Description
The Redundant Processor Unit (RPU) is designed to
operate either with a single (Main) power supply
module or with two power supply modules, the second being the Auxiliary Power Supply.
The AC Main Power Supply module accepts 115 Vac
or 230 Vac and provides regulated +5V and +12 Vdc
to the RPU backplane. AC power is connected to
terminals on the front panel and routed through a line
filter, switch and fuse to a switching power supply.
The DC Main Power Supply module accepts 24 Vdc
and provides regulated +5V and +12 Vdc to the RPU
backplane. DC power is also connected to terminals
on the front panel and routed through a line filter,
switch and fuse to a switching power supply.
Terminals on the front panel enable the user to access
electromechanical relay contacts for connection to
user indicators, or any device to be activated during
an alarm condition.
A Light-Emitting Diode (LED), visible through a lens
on the front panel, is an indicator of the status of the
module. A keyswitch mounted on the front panel is
used to select either the RUN or HOLD mode of the
RPU. A second keyswitch allows the user to select
Central Processor Unit (CPUl), CPU2 or AUTO. A
full description of the alarm relay fault conditions as
switch
and
well
as
the RUN/HOLD
CPUl/AUTO/CPU2 switch operation is given in the
RPU Manual, GEK-25366. Other features and benefits are listed in Table 1, while Table 2 shows module
specifications.

Installation
3. Disconnect wiring to AC and alarm terminals.
The RPU is designed to operate either with a single
power supply module, or with two power supply modules. The removal and replacement guidelines of a
power supply module in a dual supply system also
apply to a single supply system.
4. Remove partition faceplate between power
supplies.
When two power supply modules are used, the system
offers power supply redundancy in such a way that:
- I f both supply modules are functioning normally,
one module has the load and the other is on
standby.
- I f one power supply module fails, the other either
continues to carry the load or automatically
assumes it without affecting the normal operation
of the RPU system.
- A power supply module should be able to be
removed or installed while the RPU system is up
and running without interrupting the normal operation of the RPU system.
- However, because there may be live voltages on a
power supply module, even after the switch to that
module is turned off, the following removal and
replacement guidelines should be observed.
Power SuppIy Module Replacement (RPU running)
1. Switch RUN/HOLD switch to HOLD.
2. Remove power to failed power supply by disconnecting AC source.
5. Release quarter-turn fasteners and slide power
supply out to expose connectors located behind
faceplate.
6. Disconnect the 4 wires from the supply chassis
and 2 connectors from the monitor circuit board.
7. Remove the failed power supply.
8. Reverse the above procedure to install the
replacement module.
9. After the replacement power module has been
installed apply power to module and verify that
the POWER-ON LED is on.
10. Switch RUN/HOLD switch to RUN.
Care should be taken to avoid shorting components or leads on the module being
replaced. The free-hanging connectors from
this module should also be handled or positioned in such a way that they are not
brought into contact with conductive
surfaces.

) CAUTION )
NOTE
The alarm contacts consist of two sets of
Form C contacts. The terminals marked 1
NO and 1 NC are associated with Alarm Type
No. 1; the terminals marked 2 NO and 2 NC
with Alarm Type No. 2. Incorrectly wiring
these alarms may cause damage to your
equipment
the
RPU
Manual,
(see
GEK-25366, for further information on
Alarm Nos. 1 and 2.)
The user devices connected to each set of
alarm terminals on this module should present a resistive load drawing no more than
one ampere (1A) of current at no greater than
115 Vac/28 Vdc. Failing to observe this caution may result in damage to the module.
During normal operation, the alarm relays are
energized. During an alarm condition, when the
relay becomes de-energized, the contacts
marked 1 NO and 2 NO open, and those marked
1 NC and 2NC close.
NOTE
The two keystrokes (Run/Hold, Pwr/Auto/
CPU2) depend on the Main Power Supply for
their circuits. If the Main Power Supply fails,
the RPU firmware will behave as though the
Run/Hold keyswitch has been switched to Hold,
even if an Auxiliary Power Supply is present.
