Optional Output Relays
There is provision to add up to eight
additional relay outputs, via four
optional relay output boards which
mount in a snap-on confi guration.
Each board contains a maximum of 2
additional relays.
Engine Run Relay
The Power I/O Board houses a 10
Amp engine run relay which is used
for alarm purposes, or to power
external louvers.
Common Alarm Relay
The FD120 controller has a com-
mon alarm relay which de-energizes
whenever there are any alarm condi-
tions present. This relay is energized
under normal conditions and has LED
status indication.
Alarm Relay Rating
All alarm relays are rated 8 amps,
250Vac, resistive load only.
Programmable Outputs
Up to 10 additional, programmable
outputs (two standard; eight via
optional output boards) can be
programmed to indicate up to 45
output conditions. They can be pro-
grammed for fail safe and latch until
reset by the user. All optional inputs,
outputs and LED’s can be linked, as
required. They can also be pro-
grammed with time delay functions.
As well, two optional alarm LED’s can
be programmed for up to 28 alarm
conditions.
Power / Voltage
Universal Voltage Supply
The controller can be powered with
supply voltages from 100Vac to
240Vac by connecting to the three
input terminals L,N,G located on the
bottom left of the engine board.
Dual Output
12 or 24Vdc output is selectable via
a DIP Switch located on the battery
chargers. Note: Each controller is fac-
tory set for 12Vdc. If 24Vdc is required
from the factory, it should be noted
on the ordering information.
Line Filter
A line fi lter incorporated onto the
engine board, is used to reduce/
eliminate external incoming voltage
transients.
AC Power Disconnect
A breaker located inside the control-
ler on the Engine Board, is used
to switch on and off AC power to
the unit. It will illuminate when
energized.
DC Power Disconnect
The engine board houses two
on-board circuit breakers used to
switch on or off DC power from the
batteries.
Each breaker has an LED mounted
on the engine board that illuminates
when the breaker is energized.
Alarm and Status
Indication
Accessibility
All alarm and status LED’s as well as
the LCD Display and programming
buttons are accessible from the front
of the controller.
Product Description
The DIESEL Plus Fire Pump
Controllers from Eaton are designed
to control and monitor 12 or 24
volt, diesel fi re pump engines and
are among the most technically
advanced diesel engine controllers
available.
They are an enhanced version
of the original microprocessor-
based, FD100 Series of diesel
engine controllers. Programming is
straightforward due to the use of the
core fi rmware and menu structure
utilized in the LMR Plus Series of
electric controllers.
The controller can be ordered with
the option to display and output
current values and status, on
command, from various software
protocols.
An embedded web page for
retrieving diagnostics and history
reports, can be accessed from the
optional Ethernet communication
port. An optional RS485 serial port
can be used for direct connection to
a computer for data transfer.
Product Features
Communication
Embedded Web Page
The embedded web pages allow the
user to view the current status of
the controller as well as all amper-
age readings, set points, diagnostics,
statistics, confi guration and history.
An external computer connected via
the optional ethernet port is used to
access the pages. The specifi c data
required can be downloaded for
reference purposes.
Communication Types
USB
The USB port is used to download the
controller message history, statistics,
diagnostics, status and confi guration
data to a USB disk drive. The USB
port can also be used to upload cus-
tom messages, additional languages,
and update the microprocessor
fi rmware.
Ethernet
An external computer can commu-
nicate with the Diesel Plus controller
via the optional ethernet port. An
embedded web page will display
the controller’s current status, as well
as display all current readings, set
points and history.
Modbus
The Diesel Plus fi re pump control-
lers have the option to communi-
cate to systems using the Regular
level of Modbus (includes both RTU
and ASCII transmission modes).
Communication settings are user
confi gurable through the Diesel Plus
confi guration menu.

They can be programmed to energize
the common alarm output, link to
relays and optional LED’s and latch
until reset by the user.
All optional inputs, outputs and LED’s
can be linked, as required. They can
also be programmed with time delay
functions.
