3.3 Display Board Access Area
The display board is housed in a protective case that is
mounted on the inside of the controller door. Access to
communication ports and terminals is possible when the
controller door is open.
NOTE
To allow for uniform identification, the frame of reference when
discussing the access area is with the panel door open and the user facing
the back of the Diesel Plus controller.
Located on the bottom of the chassis is the optional USB port,
the optional Ethernet port, the I/O board communication and
power cables. The optional RS232 and RS-485 ports are located
on the right hand side of the chassis.
The display contrast adjustments can be made via the open
potentiometer dial in the back of the chassis.
3.4 Power I/O Board
The I/O Board is used for connecting all alarm input and output
signals. Optional relay expansion boards may also be
connected to the I/O board.
Refer to the Field Connection diagram mounted on the inside of
the controller door for all connection points specific to the
controller.
3.5 Engine Board
The Diesel Engine Board houses terminals 1 through 12 and 301
and 302 used to connect to the engine control panel, as well as
the incoming AC Power terminals (L, N, G).
Also located on the engine board, are the Crank relays (8CR and
9CR), the Fuel Stop relay (7CR), the DC breaker switches (CB1
and CB2) and main AC power switch.
