1. GENERAL
The Model JPC is a fusible combination motor starter with a built in pressure switch for use with pump motors such as
make-up pumps, booster pump, or `jockey' pumps which are used with automatic sprinkler systems. Some units are
supplied with a circuit breaker in lieu of the fusible disconnect (switch and fuse block).
2. INSTALLATION INSTRUCTIONS
2.1. Mounting
The JPC enclosure must be mounted in the vertical position, and in an area free from dripping and spraying water.
2.2. Safety Precaution
Before any electrical work is done on the JPC make sure the disconnect switch and the control switch are in the off
position.
2.3. Power Supply
Use branch circuit protection on the incoming line (mains). Check the motor and JPC nameplates to verify they match
the incoming line voltage, frequency and current requirements.
2.4. Wiring
All motor circuit conductors should be sized according to the National Electric Code article 430, part B. Insulation for
these conductors should be chosen so it will not be affected by the surrounding environment. The input power wiring
is connected to the fusible disconnect, and the output motor wiring is connected to the motor starter. Protect internal
components from drilling chips and debris.
2.5. Plumbing
The brass pressure sense line should be connected to the 1/4"-18 NPT female pressure connection provided on the
bottom of the cabinet.
NOTE For fire pump systems, the sense line runs from between the system side of the make-up pump check valve
and the pump side of the control valve to the pressure connection on the JPC. See NFPA standard for Fire
Pumps (NFPA-20 fig. A-7-5.2.1 for details).
2.6. Protection
Fuses are furnished according to the National Electric Code (NFPA-70) table 430-148 (Single Phase) and 430-152
(Three Phase) which is based on the full load motor current. If not specified, the full load current is taken from a
standard motor current table for Design "B", 1.15 service factor, 40% rise, 60 Hz (50 HZ for 380 Vac or 220 Vac
Controllers), A.C. Squirrel Cage Induction 2 Pole or 4 Pole motors. The table is applied to the voltage and horsepower
applicable.
The Overload Relay is furnished and set according to the motor Service Factor Amps which is based on the full load
motor current times its maximum
2.7. Service Factor
Both fuse sizes and overload (Trip) settings are shown on M.C.S. drawing SK-0844, included in standard units, or
separate label for others.

3. Start-up
After the mounting, wiring, and plumbing are completed, and the system is ready to be pressurized, initiate the
following:
1. Adjust the pressure switch to the desired turn-on and turn-off settings.
2. Close and latch the door (Operation of the disconnect switch is interlocked with the door).
3. Set the disconnect switch to the "on" position.
4. Momentarily turn the selector switch to manual position while watching the direction of the motor rotation.
If correction is necessary, open (turn off) the disconnect switch and interchange two of the motor leads.
Repeat the last two steps.
5. Turn the selector switch to the "auto" position to put the pump in service.
4. SEQUENCE OF OPERATION
4.1. General
The JPC controls a make-up pump-motor combination to maintain the pressure in a system within a selected range.
This is accomplished with an adjustable pressure switch which has independently adjustable turn-on and turn-off
setting. Refer to the wiring or schematic diagram for details.
4.2. Power Wiring
The input lines (mains) connect to the top of the Disconnect Switch DS. Power flows through the short circuit
protection motor Line (Mains) Fuses LF, and then to the Motor Starter, which is horsepower rated. The Motor Starter
consists of Motor Contactor MC and Overload Relay OLR. When the Motor Contactor Coil M is energized, Motor
Contactor contacts close to feed power through the Overload Relay to its output terminals where the motor is
connected.
4.3. Overload Relay
The Overload Relay furnished in the motor starter provide protection from excessive currents. The overload relay has
been sized and set to trip open when the motor exceeds 125% of the Full Load Current (FLA) multiplied by the rated
Service Factor (SF). Trip times vary depending on the magnitude of the current overload, the number of previous
starts, the ambient temperature of the controller, and the size of the overload element. Briefly, the Overload Relay is
sized to allow initial starting currents while protecting the motor from excessive long starting currents or excessive
running currents. (See Installation Instructions - Protection for proper sizing).
4.4. Manual Control
Control power wiring is tapped off the incoming power on the load (down-stream) side of the Line Fuses or Circuit
Breaker. It is routed to the three position (Auto-Off-Manual) selector switch.
In the OFF position, the Motor Contactor coil is de-energized to prevent the motor from running.
In the manual position, the Pressure Switch contacts are bypassed so the contactor coil is continuously energized by
the selector switch. The Overload
Relay contacts also override the manual position to again protect the motor.

CAUTION Use care when using the MANUAL (MAN) position of the control switch to avoid causing system Over
Pressure. Use extra caution with positive displacement, regenerative or other pumps capable of
generating high output pressures until or unless the presents and status of a pressure relief valve is
determined.
4.5. Automatic (Pressure) Control
In the AUTO position, control power is routed to the Pressure Switch PS. The Pressure Switch is normally closed (closes
on falling pressure). When the pressure is below the Turn-On setting of the Pressure Switch, its contacts close to
energize the Motor Contactor coil to start the motor.
In the event of excessive motor current or sustained locked rotor contacts, the thermal element of the Overload Relay
will open pilot Contacts OLC to de-energize the Motor Contactor Coil to open the Motor Contactor contacts and de-
energize the motor. After the motor and Overload Relay cool down, the Overload Relay is manually reset to re-enable
the controller and motor.
Option "1" - Control Transformer: When Option "1" is supplied, control power is supplied by a Control Power
Transformer (CPT). Its primary is supplied by two control line fuses F2 and F3. The secondary output of the
transformer is protected by secondary fuse F1. When used, control power is 115 Vac (110 - 120 Vac) rather than line
voltage. The motor contactor coil and any other relay coils are rated at 110 Vac to 120 Vac in this case.
Option "2" - Minimum Run Timer: This option is used to prevent excessively frequent pump starting. The option
consists of the Minimum Run Time Delay Relay TM. It is equipped with a Timer head TMD as well as instantaneous
contacts TMA. The timer head is equipped with an adjustment dial. The standard range of adjustment is zero to 180
seconds. The Minimum Run Timer does not operate with the selector switch in the MANUAL position.
Option "3" - Line (Mains) Fuses: Three extra line fuses are furnished to provide protection from short circuit or high
current faults. (See Installation Instructions - Protection, for proper sizing).
