6.2 Setup Program
The optional MPAC Setup Program allows you to use a
personal
computer
to
view
and
adjust
system
parameters, voltage and frequency pickup and dropout
settings, time delays, input and output functions, and
other system parameters. The software also includes a
time-stamped event log that is useful for system
diagnostics and troubleshooting. Refer to the Setup
Program Operation Manual for more information.
6.3 Control Switches
Two control switches are available, the preferred source
switch and the supervised transfer control switch. The
switches are mounted on the enclosure door.
See
Figure 6-1 for typical switch locations.
Note:
Factory-installed switches are factory-wired and
require no additional wiring in the field.

Preferred Source Switch
The
two-position,
key-operated
preferred
source
selector switch allows selection of either power source
as the preferred source. The key can be removed with
the switch in either position, locking the switch into the
selected position.
The preferred source selection
cannot be changed remotely through software or the
Modbus
r
connection. Figure 6-2 shows the preferred
source selector switch.
The transfer switch seeks and transfers to the preferred
source whenever it is available. Source N is always the
source connected to the Normal side of the transfer
switch, and Source E is always connected to the
Emergency side.
Generator engine start relays are
assigned to the the source (Source N or Source E). The
engine start relays do not change when the preferred
source switch position changes. This prevents the need
to change the wiring of the engine start relay(s) when the
preferred source changes.
