EATON LMR Plus
Effective September 2013
Electric Fire Pump Controllers
programmed for Low Suction Shutdown it will initiate the
shutdown sequence. Refer to Section 5 to program Low
Suction Shutdown. When the controller is setup for a
foam system, all references to Low Suction Shutdown
will be changed to Low Foam Level.
Low Room Temperature (Terminal 38)
When this input is in the "Connected" state, the LMR
Plus controller will signal a visual indication on the main
display board for Low Room Temperature. The Common
Alarm relay will also de-energize for remote monitoring
of this alarm.
Interlock On (Terminal 39)
When this input is in the "Connected" state, the LMR
Plus controller will not permit a start of the motor except
for Emergency Start. This input is typically used in
backup style systems. For example, the Engine Running
contacts from the backup Diesel Engine Controller are
wired into this input. When the Diesel Engine is running,
it will lock out the LMR Plus panel and prevent it from
starting.
Inputs (Terminals 40 to 48)
These are programmable inputs and will function based
on how they are programmed. Refer to Appendix G(a)
for programming details.
4.4 Output Relays
The primary control outputs of the LMR Plus controller
are dry relay contacts. These relays are comprised of
two separate "Form C" outputs for Phase Failure, Phase
Reversal, Common Alarm, Pump Run, and Future #1.
The alarm relays are UL/CSA rated at 8A 250Vac /
30Vdc.
Each relay has a green LED on the I/O board to indicate
the relay status. If the LED is "On" the relay is energized
and "Off" the relay is de-energized.
4.4.1 Relay Functions
Startup
This is the Motor Start relay. It will energize the Run
contactor(s), which initiate the motor start.
Acceleration
This relay is used on reduced voltage starting controllers
only. It will energize after the programmed acceleration
time delay. It will then switch the motor over to full
voltage.
Phase Failure
This relay is used for remote monitoring of a phase
failure alarm condition. In order to ensure dependable
operation of this relay it is energized under normal
conditions and will de-energize during alarm. This relay
can also be used to signal the loss of main power in the
fire pump controller.
Phase Reversal
This relay is used for remote monitoring of a phase
reversal condition. The phase reversal alarm is factory
set in an ABC configuration.
Common Alarm
This relay is used to signal any alarm that the LMR Plus
controller is alarming on. This relay is energized under
normal conditions and will de-energize during alarm.
Pump Run
This relay is used for remote monitoring when the pump
is running. When the amperage draw sensed by the
LMR Plus controller exceeds 20% of the motor full load
amps, the relay will energize.
Future #1
This relay can be programmed for a number of alarm or
status conditions. Refer to Appendix G(b) for
programming details.
5. PROGRAMMING
5.1 Introduction
The LMR Plus controller is fully programmable from the
device's faceplate. Users can program set points as well
as other parameters. The time, date, and set points can
only be changed from the menu system.
The menu system is broken down to eight (8) menu
groupings. They include, Language, Regional Settings,
Pressure Settings, Timer Values, Alarm Set-points,
Custom Input/Output, System Configuration Menu, and
Main Menu Password.
5.2 Navigation
In order to enter the menu system, press the Menu
button on the LMR Plus faceplate. If the main menu
password has been enabled, the user will be required to
enter the password at this time.
Once in the menu system, the Up and Down arrow keys
will provide navigation between each menu item. The
display will show the previous, current, and next menu
items. The current menu item is located on the middle of
the four line display.
All LMR Plus controller programmable features and
associated set-point possibilities are presented in
Table 1.
The following set points are programmable in the LMR
Plus controller.
