PART I: GENERAL DESCRIPTION

The basic function of the Fire Pump Controller is to start the pump motor to maintain the water system pressure. The
MV600 Controller will automatically start the pump motor upon drop in pressure in the water main or from a number
of other demand signals. This unit can be started automatically, manually or by remote manual means but cannot be
stopped remotely. The controller can be set to stop automatically or require manual stop after an automatic start.

PART II: FUNCTIONS

A. Automatic Starting From:

1. Drop in water line pressure.

2. Deluge valve operation, Option D.

3. Supervisory power failure, Option P.

B. Alarm and Signals:

1. Remote indication of pump operation: One (1) set of normally open (N.O.) and normally

closed (N.C.) contacts located in the controller operate when the pump is running.

2. Loss of power to the controller: One (1) Single Pole Double Throw (SPDT) contact located

in the controller operates for loss of power, loss of one phase, or loss of control power.

3. Phase reversal of power to controller: One (1) SPDT contact located in the controller

operates for phase reversal of power to the controller.

4. Motor Overload: One (1) SPDT contact located in the controller operates when the motor

current exceeds 125% of full load.

5. Power ON pilot light: his light is on when the contactor is racked in, indicating that power is

available and the controller is set for operation.

6. Phase reversal pilot light: This pilot light is on whenever there is a phase reversal of the

power to the controller.

7. Motor Tripped pilot light: This pilot light is on when the Overcurrent Monitor has tripped

and deactivated the contactor coil circuit.

8. Engine Lockout (Option E): When an engine drive system is used as a backup a normally

open auxiliary contact on the motor contactor is provided to prevent the engine from starting if
the electric motor is running.

9. Electric Motor Lockout (Option M): The electric motor lockout is generally used in con-

junction with engine lockout above. If the engine is running due to a power outage, or other
reasons, the electric motor can be locked out until the engine is stopped.

C. Sequential Starting: This feature is provided to allow a time delay between pressure drop and actual start-

ing of the motor which guards against nuisance starts. It also allows for multiple motors to start at
delayed intervals to reduce inrush surges on the electrical line.

D. Principal Components of Controller:

1. Drawout/Disconnect

2. Fuse Rack

3. Contactor

4. Pressure Switch

The incoming line is connected directly to the high voltage buss. From there, the power is fed to the line
side of the motor contactor (1MC) via the stab connectors. (This is accomplished by the Drawout feature)
The contactor is operated either manually or automatically to start the motor.
