Model MP430/435 Wye-Delta Start Microprocessor Electric Motor Fire Pump Controller
Specifications
General Controller Description
The Fire Pump Controller shall be factory assembled,
wired and tested as a unit and shall conform to all
requirements of the latest edition of NFPA 20, NFPA
70 and be Third Party Listed by Underwriters
Laboratories (UL) and Approved by Factory Mutual
(FM). The controller shall be available for 208, 230,
380-415, or 480 volt three phase power.
Controller Equipment Features
The controller shall include the following standard
features:
•
NEMA Type 2 drip proof metal freestanding
enclosure
•
The controller shall be designed for Wye-Delta
starting and shall start the motor in the Wye
configuration drawing 33% of normal current, then
connect the motor in the Delta configuration
applying full voltage.
•
AUTO, MANUAL, TEST, and OFF mode buttons
illuminated with colored LED's for controller mode
operation
•
Operator Interface Device (OID) with 4 lines by 20
character display with large character backlit LCD
capable of being read in both direct sunlight or dark
lighting conditions
•
12 pushbuttons for easy screen navigation, system
mode changes, alarm reset, and horn silencing
•
Multicolored LED's for alarm and mode
annunciation
•
LEDs shall be labeled with removable labels to
allow for easy field modification if additional alarms
and/or language changes
•
All controller settings shall be programmable
through the OID and shall be protected by two
password levels
•
All features shall be enabled or disabled through the
OID, no jumpers or external wires shall be needed or
allowed to activate or de-activate a feature
•
The system status data shall be displayed on the
OID. The displayed items shall include: System
pressure, Phase to Phase (AB, BC, AC) voltage,
Phase current (A, B, C), Current time and date,
Number of starts, Total motor run hours, Displayed
countdown timers for: Sequential motor start and
motor stop.
•
Audible horn with silence feature for silencable
alarms
•
Lamp test feature
•
English or Spanish languages selectable through the
OID
•
Microprocessor based logic with real time/date clock
capable of running a minimum of 14 days without
AC power connected to controller and non-volatile
flash memory to permanently store the continuous
pressure log, event log, alarm log and all user
changeable set points and system data. Battery
backup of any kind not allowed.
•
Input and output status LED's to provide visual
indication of each discrete input's or output's on/off
status
•
One RS232 Serial Port
•
One USB 1.0 Port
•
One RS485 Serial Port
•
All wiring terminals on PCB's shall be removable
type
Auxiliary alarms:
As standard the controller shall include 6 discrete
auxiliary inputs, 9 form 'C' auxiliary relay outputs.
These auxiliary inputs and outputs are in addition to
those mandated by NFPA 20. All auxiliary inputs,
outputs, and OID LED's shall be field programmable
through the OID. This permits a multitude of
customizable controller configurations to meet each
installations unique needs without adding cost to the
controller. The use of jumpers, soldering, or other
external components are not allowed.
The user can select any 9 of the following auxiliary
alarms that can be programmed and recorded in the
event/alarm logs and annunciated with an LED and
output relay contact for conditions such as:
LOW PUMP ROOM TEMP
RESERVOIR LOW
RESERVOIR EMPTY
RESERVOIR HIGH
FLOW METER ON
RELIEF VALVE OPEN
LOW SUCTION PRESSURE
HIGH PUMP ROOM TEMPERATURE
LOW FIREWATER PRESSURE
LOW PURGE PRESSURE
LOW GEAR OIL PRESSURE
LOW GEAR OIL TEMPERATURE
GAS DETECTION
HIGH VIBRATION
EMERGENCY POWER ON
PUMP ROOM DOOR OPEN
Data logging:
The controller shall have three separate data logs for
storing system data that is readable through the OID or
printable on the internal printer. These logs shall be as
follows:
Pressure Log: The controller shall have a Pressure log
with continuous pressure recording of minimum of 7
days and be capable of storing more than 30 days of
data. The pressure log samples shall be time and date
stamped and stored in permanent non-volatile flash
memory. The pressure log shall be searchable by each
sample, by minute, or by hour.
Event Log: The event log shall be capable of storing no
less than 4000 events. These events shall include, but
is not limited to, any of the following events/alarms:
PUMP RUNNING
POWER AVAILABLE
PHASE REVERSAL
MOTOR OVERLOAD
REMOTE START
LOCAL START
PUMP ON DEMAND
SYSTEM FAULT
AUTO MODE
MANUAL MODE
OFF MODE
PRESSURE TRANSDUCER FAULT
PUMP FAILED TO START
LOW INTAKE SHUTDOWN ALARM
SUPERVISORY POWER FAILURE
LOW PRESSURE
AUTO WEEKLY TEST START
UNDER FREQUENCY
OVER FREQUENCY
LOW ZONE / HIGH ZONE CONTACTS
HIGH DISCHARGE PRESSURE
NO LOAD CONDITION
Alarm Log: The Alarm Log shall be a separate subset
of the event log and shall display the last 10 alarms
recorded in the system.
Each event or alarm recorded in the either event log or
alarm logs shall have the following data recorded with
the event/alarm:
•
Time and Date of Event or Alarm
•
System Pressure
•
Descriptive Text Message of the Event/Alarm
•
Motor Running Status
•
Phase to Phase Volts
•
Phase Amps
The internal logic of the controller shall be capable of
operation in a temperature range of 0ºC to 50ºC and
high, non-condensing, humidity levels.
The controller shall be manufactured by Metron.
