Operation
Operational Modes
Once the loads are properly terminated, the only operational
consideration is whether to configure the PCU 2100 for Dual
Mode or Redundant Mode operation. A rear panel switch pro-
vides the selection, and a front panel LED indicates operating
mode.
DUAL MODE
Dual Mode operation configures both banks of the PCU 2100
to operate as independent power supply systems. In this
mode, all output circuits are fully active on each bank and
available for simultaneous use. In Dual Mode, a total of 16 PCU Series paging stations and 20
ControlMatrix control panels can be powered simultaneously. In Dual Mode there is no redundancy,
but the fault supervision and protection features are active.
REDUNDANT MODE
Although all circuits are supervised and protected, using the PCU 2100 in Redundant Mode provides
an additional level of stability. When operating the PCU 2100 in Redundant Mode the total capacity is
reduced to half of what Dual Mode provides. This is because the Bank B circuits are used as standby
circuits for loads connected to Bank A. When the PCU 2100 is in Redundant Mode, there is 1:1
redundancy for each load. If an output fails, the stand-by bank (Bank B) will take over, providing
seamless operation. In addition, the operator is notified of the failure by the integral fault contacts.
When using the PCU 2100 in Redundant Mode, only the Bank A output circuits are used. All Bank B
outputs are disconnected from their connections and cannot be used. The Bank B circuits operate in
“standby”, providing full 1:1 redundancy for each corresponding Bank A circuit. The switching
between redundant circuits is seamless, providing hands-free operation. Fault supervision alerts the
operator of a failure, while operation continues.
