Figure 1-9 Controller Circuit Boards and Fuses
(Controller Top View)
Indicator (Status) Circuit Board includes the LED
status lamps, alarm horn, and generator set master
switch.
Interconnection Circuit Board provides the terminal
strips to connect the controller (customer) connection
board and/or dry contact kits and three DC fuses (F1, F2,
and F3). See 6.1.3 for more information.
Keypad (Switch Membrane) Circuit Board provides
the keypad to navigate the generator set displays and
enter data.
Digital Display Circuit Board provides the vacuum
fluorescent display (VFD) for monitoring the generator
set functions and output values.
Main Logic (Microprocessor)/Communication
Circuit Board provides the controller operation logic
and provides PC communication locally (direct) or
remotely (via modem) using RS-232 or RS-485
connectors.
1.2.5 Fuses
AC Circuit Fuses (TB5). Fuses are located inside the
controller. See Figure 1-9.
D 1.5-Amp (V7) fuse protects L1 sensing input to
interconnection circuit board.
D 1.5-Amp (V8) fuse protects L2 sensing input to
interconnection circuit board.
D 1.5-Amp (V9) fuse protects L3 sensing input to
interconnection circuit board.
DC Circuit Fuses fuses are located on the controller
interconnection circuit board.
D 5-Amp Remote Annunciator (F1) fuse protects the
dry contact kit if equipped and the controller panel
lamps.
D 5-Amp Controller (F2) fuse protects the controller
circuitry.
D 15-Amp Engine and Accessories (F3) fuse protects
the engine/starting circuitry and accessories.
1.2.6 Terminal Strips and Connectors
Terminal strips and connectors for inputs and outputs
are located on the interconnection circuit board. See
Section 6, Accessories.
TB1 Input Connection Terminal Strip provides input
connections for remote start and emergency stop
(E-Stop).
TB2 Analog Input Connection Terminal Strip
provides analog input connections, including non-ECM
sensor connections.
TB3 Accessory Power Output Connection Terminal
Strips provides a generator set power supply for factory
use.
TB4 Digital Input Connection Terminal Strips
connect external devices (engine ECM and user
supplied) to the generator set digital inputs.
P23 Connector connects the interconnection circuit
board to the controller (customer) connection terminal
strip (connector P25) inside the junction box. See 6.1.3
for more information.
