INSTALLATION & MAINTENANCE
MANUAL FOR LMR ELECTRIC
FIRE PUMP CONTROLLERS
In order to familiarize yourself with the LMR Electric Controllers, please read the instruction manual thoroughly and carefully.
The parts of this manual that refer to the Run Period Timer (RPT) do not apply to the FDF - Foam Pump Controller. FDM -
Medium Voltage controller information is available in section 16.0 of this manual. Additional medium voltage information
can be found in Instruction Bulletin: I.B. 48022.
1. Installation and Mounting
of
LMR Controller
Carefully unpack the controller and inspect thoroughly.
The controller should be located as close as is practical to
the motor it controls and shall be within sight of the electric
motor, preferably ten feet or less.
The LMR controller is designed for either wall or floor
mounting. Note that the controller is not free standing and
must be mounted with feet or bolted securely to a wall. For
dimensional and weight data please refer to the respective
data sheets for the various types of Fire Pump Controllers.
2. System Pressure Connection
The LMR is equipped with a Pressure Transducer. The
controller is provided with a ¼" NPT female system
pressure connection located on the bottom, external side
of the enclosure. The connection should be installed as
per NFPA, pamphlet No. 20.
NOTE: Water lines to the pressure switch must be free
from dirt and contamination.
The actual pressure is displayed on the bottom left hand
corner of the LCD Display. Precise start and stop pressure
set points can be programmed into the controller. Refer to
Section 6 for programming instructions. A print-out of
pressure readings is provided during alarm situations or
pressure deviations.
The pressure transducer and internal plumbing components
are rated for a maximum of 600 PSI.
3. Electrical Connections
NOTE: Do not drill or install incoming cables above the
controller card.
*OTHERWISE WARRANTY IS VOID*
All electrical connections should meet national and local
electrical codes and standards.
The controller should be located or so protected that they
will not be damaged by water escaping from pumps or pump
connections. Current carrying parts of controllers shall be a
minimum of 12 inches (305 mm) above the floor level.
• Prior to starting, verify all data on the nameplate such
as, catalog number, AC line voltage, horsepower and
frequency. Also check all wiring connections and
system pressure.
• Inspect all electrical connections, components and
wiring for any visible damage and correct as necessary.
Ensure that all electrical connections are tightened
before energization.
• Refer to the appropriate wiring schematic drawing
included in this manual (page 15), and/or affixed to
the enclosure door, for all wiring information pertaining
to the incoming AC power supply and motor wiring.
• Install necessary conduit using proper methods
and tools.
• Incoming AC line voltage is clearly marked L1, L2,
L3 and ground, located at the top of the enclosure.
3.1 Wire Sizes
• For control wiring, use #14 AWG wire for all
electrical connections.
• For power wiring sizes refer to TABLE 1, on page 16.
3.2 Electrical Checkout Instructions
WARNING: The following procedures should be carried
out by a qualified electrician familiar with the electrical
safety procedures associated with this product and its
associated equipment.
3.2.1 To ensure the pump does not start upon energizing
the controller, make sure that the pressure at the
transducer (main controller sensing line) is 5 PSI
or greater – or – hold the STOP button while
energizing. The
LMR’s START PRESSURE is
factory set at ‘0’ PSI. Once the controller is
energized the system pressure can be viewed on
the LCD display. Refer to Section 4.3. Placing a
jumper between terminals 37 & 49 will lock the
controller out ensuring that the pump will not start
unexpected. After it is determined that the pump will
not start this jumper should be removed. (For Foam
Pump controllers, the controller can be started by
manual means as well.)
3.2.2 Phase Sequence Check: The LMR controller is
designed to be phase sensitive. L1, L2 & L3 should
be connected to A, B & C phases respectively.
Energize the controller by closing the Isolation
Switch (MIS) and Circuit Breaker (CB). If the phases
are connected incorrectly, the “Phase Reversal”
LED on the alarm display will be lit. To correct this
condition, refer to Section 3.5 to correct the DP2
switch setting. Re-energize the controller.
