Section 4 - Controls
4.1 Control System Overview
The PowerCommand Control (PCC) which is a micro-
processor-based control can be provided in a
mechanical and electronic version. All generator set
control functions are contained on one circuit board
(Base board). The Base board provides engine
speed governing (optional), main alternator voltage
output regulation, and complete generator set moni-
toring. The operating software provides control of the
generator set and its performance characteristics and
displays performance information on a digital display
panel. It accepts menu-driven control and set-up
input from the push button switches on the front
panel.
For specific information on the control panel for your
unit, please refer to the following documentation pro-
vided separately from this manual.
Table 4-1
4.2 Control Wiring Installation
The generator set control panel box contains connec-
tion points for remote control and monitor options.
CAUTION
Stranded copper wire must be used for all cus-
tomer connections to the control panel. Solid
copper wire may break due to genset vibration.
Use flexible conduit for all wiring connections to the
generator set. All conduit used for control wiring is
attached to the control housing.
Route the control wiring through the control housing
and access holes. Access holes should be used
according to where the wires are terminated inside
the control box.
A compression type strain-relief connector should be
used to prevent dust, insects, etc. from entering the
control box.
Use cable ties to keep control wiring away from sharp
edges and AC power cables within the control hous-
ing.
4.3 Remote Monitor/Control Connections
(PCC)
Customer monitor/control connections are attached
to terminal block TB-1. Optional equipment such as a
remote annunciator panel, sensing devices used to
monitor genset operation, remote start/stop switches,
battery charger, etc. are attached to TB-1. Refer to
the customer connections diagram in Section 7 -
Wiring Diagrams.
CAUTION
Always run control circuit wiring in a separate
metal conduit from AC power cables to avoid
inducing currents that could cause problems
within the control.
