Standard Features
Series MP430/MP435
Wye- Delta motors have all six leads brought out to the motor
terminal box. These leads are connected by the controller first in the
Wye configuration which draws only 33% of normal starting current
and develops 33% of normal starting torque. After a short time delay,
the controller then connects the motor winding in a Delta
configuration, applying full voltage and drawing full load running
current and developing full running torque.
With the MP430 open transition types, there is a very short period of
time where no voltage is applied to the motor during transition from
Wye to Delta connections. This condition can cause current surges
or disturbances being fed back into the main power source. The
magnitude of the surges is proportional to the phase difference
between the voltage generated by the running motor and the power
source. These transients can in some instances, affect other
equipment which are sensitive to current surges.
The MP435 closed transition types provide a smoother transition from
Wye to Delta by keeping the motor continuously energized during the
transition period. This is accomplished by means of resistors which
are connected in the circuit during the momentary period of transition
from Wye to Delta.
Metron Wye-Delta Controllers incorporate a mechanical as well as
electrical interlock to prevent the Wye connecting contactor from
being energized at the same time as the Delta contactor.
An emergency start lever to close starting contactor independent of
automatic control circuits. When used, this lever will bypass the
reduced current start feature and start the motor with full inrush
current drawn from the power source.

PART I: GENERAL INFORMATION
The basic function of the model MP Fire Pump Controller for electric motor driven fire pumps is to automatically start the fire pump
electric motor upon a drop in pressure in the water main, or from a number of other demand signals. This controller provides alarm
and/or alarm shutdown protection for various motor and power failures. Stopping of the motor after the demand period is over may
be either manual or automatic. This controller also includes an automatic weekly test starting feature.
PART II: FUNCTIONS
Equipment is provided in the Controller to provide the following functions:
A. Automatic Starting From:
a. Drop in water line pressure
b. Operation of optional remote start switches, such as remote start switch, deluge valve switch, fire alarm switch, etc.
c. Weekly test timer
B. OID – Operator Interface Device - Provided for display of alarm functions, system pressure, 3 phase AC volts, 3 phase motor
current and alarm conditions, etc. Includes buttons for Auto, Test, Manual and Off. Also features a 4 line by 20 character LCD
for display
C. Alarms and Signal Lights - Twelve (12) Standard lights are provided to give visual signals for; "Power On”, "System Fault”,
“Phase Failure", "Phase Reversal", “Pump Running”, "Pump Failed to Start","Motor Overload", "Low Pressure",
"Motor Lockout", “Local Start”, “Remote Start” and “Deluge Start”. When a transfer switch is supplied, additional lights
are provided for “Transfer Switch in Normal”, “Transfer Switch in Emergency” and “Emergency Iso Sw Open”. In
addition the mode buttons have LED’s on the button indicating “Auto”, Manual”, “Test”, or “Off” mode.12 additional lights
(9 when a transfer switch is supplied), configurable by the factory, are provided for "Pump Room Alarms". An audible alarm
horn is mounted on the front of the cubicle for sounding in the event of failure. Terminals are provided for remote failure
indication of the following:
"Power Available"
"Phase Reversal"
"Pump Running"
"Controller Not in Auto"
D. A data logger is provided as standard to record system pressure along with numerous alarm conditions and system events. The
data can be displayed on the OID or can be downloaded to a PC through the RS232, RS485 or USB port provided on the main
system board or printed to the internal printer (if supplied).
E. A weekly test timer is supplied to automatically start the pump any set day of the week, at a set time of day, and a preset run
time. See System Config Screen 106.
F. “Start” Push button – A green push button is provided on the exterior of the cabinet to manually start the pump. When this
button is pressed, the motor will continue to run until it is stopped using the Stop push button.
G. "Stop" Push button - A red pushbutton is provided on the exterior of the cabinet to stop the pump in Automatic only after
starting causes have returned to normal. This returns the controller to the automatic position. In the Manual mode this will also
stop the pump after starting via the Start push button.
H. Cabinet - A heavy gauge steel cubicle encloses the controller.

PART III: OPERATION OF THE CONTROLLER
A. When the controller is in the "Auto" mode, the main circuit breaker and isolation switch are in the "On" position, the controller
is in standby condition ready to start the pump automatically. A green pilot light above the "Auto" button will illuminate in
this mode. Also, the Power On light should be ON indicating that all power is available and the controller is ready to start the
pump.
When the water pressure drops below a level, which is set in System Config Screen 101, the Controller will actuate the starting
sequence based on the Model of the controller selected in Screen 301. If the pump fails to start after a set time delay (Screen
#103), the "Pump Failed to Start" light will illuminate, and the alarm horn will sound. In addition, the "System Fault” light
will illuminate.
The panel is wired so that optional remote start switches may be used, such as Deluge Valve, Remote Start pushbutton, Fire
Alarm switches, etc. The Deluge Valve Switch Option (Screen #124), is a normally closed switch that when opened starts the
pump similar to the pressure drop start. In addition, when “Supervisory Power Failure Startup” feature is enabled (System
Config Screen 116), the Controller will automatically start the pump upon loss of a Separate 120VAC Supervisory Power, after
an adjustable time delay (System Config Screen 117).
If the pump stops while running, and there is still an auto start demand, the control will attempt to restart the pump. If the pump
fails to start the "Pump Failed to Start" light will illuminate and the alarm will sound. If, while the pump is operating, the
motor current exceeds a set overload value (Screen #319), the “Motor Overload” light will illuminate and the alarm will sound
indicating motor overload.
The Controller may be configured as either "Manual" or "Automatic" stop as required (System Config Screen 104).
"Manual" stop is set as standard. When Automatic stop is enabled the stop timer is preset at the factory to 10 minutes. Longer
time settings can be set in System Config screen 105. When “Automatic Stop” is disabled, the pump will continue to run even
though the pressure switch or other remote starting switch returns to its normal position. The pump can be stopped immediately
only by pressing the stop button or by pressing the Off mode button. If set up for "Automatic" stop, the pump will be stopped
automatically upon restoration to normal of whatever demand switch started the pump providing it has run at least 10 minutes or
longer as set in System Config screen 105. If the demand period was less than the time set on the auto stop timer, the pump will
continue to run until the timer times out and then will stop.
B. When the "Test" mode button is pressed for two or more seconds, the pump will be started by causing a drop in water pressure
if the Solenoid Drain Valve Option (Screen #108) is selected. If the Solenoid Drain Valve Option is set to NO, the unit will start
automatically similar to the Deluge Valve switch start feature. Failure alarm circuits will be operative in the "Test" mode. This
method of starting provides a test of the Controller, thereby assuring proper operation when required. The pump will run
continuously in this position until the "Stop" push button is pressed or the “OFF” mode button is pressed.
C. Periodic Self Testing - The Weekly Test Start Timer can be set to give test runs on any day of the week and time of day desired.
A timing element is incorporated in the controls so that when the pump starts in this manner, it will run for a definite time before
it shuts down. See System Config Screens 109 through 112 to set the starting time and length of pump running. See item B.
above. The Weekly test feature will also use the Solenoid Drain Valve option to start the pump if it is enabled as described in B.
above. If Screen #113 (Stop Motor During Test on Alarm) is set to Yes, the motor will be stopped should any alarm condition
occur during the weekly test operation.
D. Provision for sequential starting is accomplished by the use of adjustable time delay on pressure drop starting or “Deluge Valve”
starting. On Multiple Pump installations these timers are set sequentially and progressively longer in time to prevent more than
one (1) pump from starting simultaneously with another pump. Failure of the lead pump to start will not prevent subsequent
pumps from starting. The time delay on starting is set in System Config Screen 103.
E. Emergency Manual Operation: Emergency manual operation is provided in case of failure of control circuitry. This lever is
manually moved to the "On" position and must be manually latched in the "ON" position or it will return to "Off" when released.
The lever should be moved from the "Off" position to the "On" position in as quickly a motion as possible to prevent burning the
contacts. The circuit breaker should be turned off to disconnect the circuit before releasing emergency lever. This lever is for
emergency use only. A mechanical interlock switch is connected to the emergency lever to operate the contactor electrically when
all circuitry is functioning properly. This is provided to prevent inadvertent slow closing of contactor and burning of contacts.
F. Series MP400 Primary Resistance Start: There are two contactors supplied along with a set of starting resistors. The starting
contactor is connected in series with the resistors to reduce the voltage to the motor for a preset time. After this preset time delay
(See Screen #314) the main contactor will close in parallel with the starting contactor and resistors and thus apply full voltage to
the motor. If the motor is not connected for this test, there will be no voltage drop across the resistors and full voltage will appear
at the output terminals of the contactors as soon as the starting contactor closes.

Page 5 of 25
G. Series MP420 Part-Winding Start: There are two contactors for part-winding start. The start contactor will close immediately
on demand and the other will close after a preset transition time delay (See Screen #314). Full voltage will be present at the output
of both contactors.
H. Series MP430 Wye-Delta Open Transition: There are three contactors for wye-delta starting. The start contactor and the
shorting contactor will close immediately on demand. This connects the motor leads in the wye configuration. After the transition
time delay the shorting contactor opens and the run contactor closes, thus connecting the motor windings in the delta
configuration. The motor will now run at full speed and deliver rated horsepower to the load.
I. Series MP435 Wye-Delta Closed Transition: The operation of the Series MP435 is almost the same as the Series MP430.
There is an additional resistor contactor and a set of transition resistors which provides power to the motor windings during
transition from the wye connection to the delta connection. After the transition time delay this contactor closes, which connects
the resistors to the motor windings. After the resistor contactor closes the shorting contactor opens, which in turn allows the run
contactor to close, thus connecting the motor windings in the delta configuration. The motor will now run at full speed and deliver
rated horsepower to the load.
J. Series MP450 Autotransformer Start: There are three contactors for autotransformer starting. The start (autotransformer)
contactor and the autotransformer neutral contactor will close immediately on demand. This connects the motor leads through the
autotransformer to reduce the voltage to the motor. After the transition time delay the run contactor closes and then the start
contactor and autotransformer neutral contactor open, thus connecting the motor to full voltage. The motor will now run at full
speed and deliver rated horsepower to the load.
K. Series MP700 Solid State Soft Start: There are two contactors for solid state soft starting. The solid state starter line contactor
will close immediately on demand and ramp the motor up to speed depending on the solid state starter configuration parameters.
After the transition time delay the run contactor closes and bypasses the solid state starter, thus connecting the motor to full
voltage. The motor will now run at full speed and deliver rated horsepower to the load. When the stop command is received and
the controller is set up for the ramp stop option (Screen #106) the motor will ramp down in speed over a fixed time delay (Screen
#107) until it stops.
Note: When using the emergency manual start handle, the soft start unit may display an “OCF” fault condition. This is
normal. The unit is not malfunctioning. When the proper stop sequence is used according to paragraph E above, the fault
condition will be cleared and the soft start unit will be ready for a normal start.
PART IV: INSTALLATION AND TEST PROCEDURE
A. INSTALLATION
The Fire Pump Controller has been assembled and wired at the factory in accordance with the highest workmanship standards.
All circuits and functions have been thoroughly tested to assure correct operation when properly installed. The installer should
be completely familiar with the external hookup of the pump junction box to the terminal bar in the Controller. All local electric
codes should be used for proper installation, wiring and grounding of the controller prior to startup.
A weekly test drain solenoid valve may be provided to relieve water pressure to the pressure transducer thus initiating the start
sequence. This test simulates an actual start demand. Since the Controller operates the drain valve only momentarily, a small
amount of water is drained off. The water pressure sensing line to the Controller from the pump must be thoroughly flushed
before connection to the Controller in order to remove chips, particles, or other matter, that could enter the plumbing
components in the Controller.
Controllers configured with "Automatic Stop" enabled may be changed to "Manual" stop by disabling this feature in System
Config Screen 104. If deluge valve switches are to be used for starting, enable the Deluge Valve Option in Config Screen 121
and connect the remote normally closed switch to terminals 74 and 111.
B. TEST PROCEDURE
All of the following tests should be made on each unit after installation. If each test is satisfactory, the operator may place the
control switch in "Auto" mode and depend upon the panel operating properly when required. Also, any one or all of these tests
may be carried out at any time after installation, if so desired. NOTE: If the Supervisory Power Failure Start Option has
been Enabled (Screen #116) and 115 Volts A.C. is not connected to Controller, the "System Fault" light will illuminate
and the controller will start automatically after a time delay. The 115VAC must be turned on to prevent the pump from
starting.
Phase Reversal Alarm – Upon initial power up, if a phase reversal alarm should sound, the following process can be used to
correct the alarm. If a test of the motor rotation indicates that the motor is turning opposite of the correct direction, the motor

Page 6 of 25
motor leads must be reversed to cure the condition. Turn the controller circuit breaker and isolation switch off and verify that
incoming power on the load side of the controller isolation switch has been disconnected. Then reverse any two of the motor
leads. If there are multiples sets of motor leads, i.e. Part Winding start or Wye-Delta start, then both sets of leads must be
reversed. Be certain to change the same set of wires at the two contactors. Then turn the controller isolation switch and circuit
breaker back on and check for correct rotation of the motor and then follow the procedure below to correct the Phase Reversal
alarm.
If the motor is turning the correct direction but there is a Phase Reversal alarm then this can be corrected as follows. Press the
Config button on the front of the OID. Press the Config (2) button again to access the User Preferences Setup screens. Press the
Up arrow key once. The OID should then read “223 User Preferences – Reversed Phase”. Press the Change/Enter button. The
system will then ask for a password. Enter 1111 and then press enter. Press the Up or Down arrow key to change the setting in
the lower left hand corner of the screen from “No” to “Yes” then press the Change/Enter button. After a few seconds the “Phase
Reversal” LED will reset. Also, press the Silence\ Reset button for approx. 3 seconds to silence the audible alarm.
INPUT/OUTPUT STATUS INDICATOR LIGHTS
Light Emitting Diodes (L.E.D.) lights have been installed on the microprocessor module to indicate the status of each input and
output terminal. Status indication for the standard functions is given below:

a. AUTOMATIC STARTING TESTS:
1. Place control in "Auto" position.
2. Bleed off pressure in system until pressure drops below the low set point.
3. Pump should start automatically and continue to run after pressure rises above the high set point, if arranged for
"Manual" stop. If arranged for "Automatic" stop, pump will continue to run for time set on Auto Stop Timer and
then stop.
4. Press the "Stop" push button to stop the pump.
5. Repeat tests for each demand switch such as deluge valve (if enabled), remote start, etc.
b. PERIODIC WEEKLY START TEST:
1. Pressure must be up and all other demand switches de-activated.
2. When the current day and time of day matches the settings in System Config screens 107 and 108, the solenoid drain
valve will energize (if enabled and supplied, see screen #108) and the pump will start. It will continue to run for the
amount of time set and then stop automatically.
c. SETTING PROGRAM WEEKLY TEST TIME: System Config screen 109 through 112.
d. REMOTE START SWITCH CIRCUITS: Field wiring terminals are provided on the controller so that optional remote
start switches such as Remote Pushbutton Stations, Deluge Valve Switch, Fire Alarm Switches, etc., may be used to start the
pump. Two (2) sets of terminals are provided. Terminals #112 and #31 are used for remote manual start push buttons (close
to start). Terminals #111 and #31 are used for remote Deluge Valve Switch or other remote automatic start switches (open to

start). Upon automatic start from this type of switch, the pump will be stopped either automatically after the demand switch
de-activates and Pump Auto Stop Timer times out, or manually at the Controller. Terminals #111 and #31 must have a
jumper installed if a remote Deluge switch is “Enabled” but not to be used. When the controller is shipped from the factory
Deluge Valve start is Disabled (System Config screen 121).
e. AC POWER FAILURE STARTING: If this feature has been enabled it can be tested by disconnecting the supervisory
power 115 V.A.C. to the Controller. After the preset time delay (which is specified in System Config screen 112), the
Controller will commence starting of the pump. The "System Fault" LED will illuminate and the alarm will sound.
f. NORMAL OPERATION – AUTOMATIC: Press "Auto" mode button on OID. A green "Automatic Mode" light will
illuminate and the pump will automatically start upon drop in pressure or operation of other start switches. If the Auto Stop
Timer is disabled (Manual Stop) the pump must be turned off at the Controller. When the Auto Stop Timer is enabled, upon
termination of the demand signal, the pump will run for the length of time left on the Auto Stop Timer and then will stop
automatically.
g. AN ADJUSTABLE SEQUENTIAL START TIMER IS SUPPLIED FOR MULTIPLE PUMP INSTALLATION:
Normally, the leading pump Controller will not have a delay timer and will commence starting of the pump immediately
upon operation of a demand signal (other than Power Failure which is time delayed). The subsequent Controllers will have a
time delay which is adjustable from 0 to 999 seconds. Each time delay should be set with progressively longer times on each
subsequent pump. The recommended time interval is ten (10) to fifteen (15) seconds. This may be extended or shortened as
required by the local authorities having jurisdiction.
h. PUMP ROOM ALARMS: Field terminals may be provided for various inputs from pump room alarms. These alarms
include: Low Pump Room Temperature, Reservoir Low, Reservoir Empty, Low Suction Pressure, Relief Valve Discharge
and/or Flow Meter On etc. A maximum of twelve (12) (or nine (9) if a transfer switch is supplied), pump room alarms is
available. Each auxiliary alarm is configurable so that the alarm horn may or may not sound and the light will come on when
the alarm sensor contacts close. These pump room alarms can be silenced with the “Silence” push button on the OID if they
have been configured as silenceable.

PART V: OPERATOR INTERFACE DEVICE (OID) USE AND NAVIGATION
The Operator Interface Device (OID) provides visual indication of the alarms, status of system parameters, and an interface to
change set points to configure the controller to operate appropriately for various installation requirements.
Labeled LED
Annunciator Common Tasks Performed Using The OID
Silencing Horn: If a horn is sounding and the alarm is silenceable, a quick
press of the [SILENCE/RESET/ESC] will silence the horn (less than 1
second press).
Resetting Alarms: If the alarm condition has cleared, press and hold the
[SILENCE/RESET/ESC] button 2 to 5 seconds to reset alarms.
Operating Mode Change: The operational mode that the controller is in can
be changed by pressing the [AUTO] [MANUAL] or [OFF] buttons. An LED
will illuminate on the appropriate button indicating the mode of operation the
controller is in.
Test Mode: When controller is in Auto Mode, pressing and holding the
[TEST] button for two or more seconds will open the pressure drain solenoid
thus dropping the pressure, which causes the controller to start the pump.
Pressing and releasing the [TEST] button in Manual Mode directly controls
the opening and closing of the drain solenoid. The pump will not
automatically start when in Manual Mode.
Lamp Test: To illuminate and check all the OID LED’s and the horn, press
and hold the [SILENCE/RESET/ESC] button 5 or more seconds or until all
the lights turn on.
