CBWP - CONTROL BOX - WIRING DIAGRAMS
TO PREVENT HAZARD OF FATAL OR SERIOUS ELECTRIC SHOCK :
Connect this control enclosure, all metal plumbing, and the motor frame to the power supply grounding termi-
nal using copper wire complying wich electrical codes. A ground wire at least the size of power wires complies.
Smaller wire may comply under some conditions
Permanently close all unused wiring operning in this and other equipment.
Switch off power to this circuit at the power supply panel (not in this control) before working on or around the
control, pipes, cable, pump or motor.
INSTALLATION AND OPERATION:
Mounting – Be sure that the control box is mounted in a vertical position with the top side up. If it is mounted
in any other position, the starting relay may not function and the overload may trip.
Connections – The control box should be wired to the line and the motors as shown in the diagram.
The pump will not operate without this control box.
Operation without the control box will burn out the motor. Installation of this motor and control must include
circuit and component protection in compliance with U.S. National Electrical Code or Canadian Electrical Code,
Part.1
Protection – Trip of overload indicates a shorted capacitor, voltage problems, an overloaded or locked pump,
or the start relay should be replaced. Reset and analyse for tripping cause.
Do not remove or short out overload protection, since doing so is likely to cause motor burnout.
Use 75° C copper wires/conductors only, 14-10 AWG, tightening torque 20lbs*inch.
For guarantee the Enclosure Type 3R need fix the box using 2 fixing holes.
CHECKING PROCEDURE: BE SURE POWER IS TURNED OFF:
A)
OVERLOAD (Push reset button to make sure contacts are closed)
1.
Ohmmeter setting: (Rx1).
2.
Terminal connections: ohmmeter leads to overload terminals.
3.
Ohmmeter reading: should not be over 0.5 ohms.
CAPACITOR (Disconnect one lead from each capacitor prior to checking)
B)
1.
Ohmmeter setting: (Rx1000).
2.
Terminal connections: individual capacitor teminals.
3.
Ohmmeter reading: pointer should swing toward zero then drift back toward infinity.
RELAY COIL (Disconnect lead from terminal 5)
C)
1.
Ohmmeter setting: (Rx1000).
2.
Terminal connections: "5" and "2" on relay.
3.
Ohmmeter reading: 4500-7000 ohms
D)
RELAY CONTACT (Disconnect lead from terminal 1)
1.
Ohmmeter setting: (Rx1).
2.
Terminal connections: "1" and "2" on relay.
3.
Ohmmeter reading: should be zero.
E)
MAGNETIC CONTACTOR ONLY (Disconnect 1 coil lead)
1.
Ohmmeter setting: (Rx100).
2.
Check coil resistance: 1000-1400 ohms.
3.
Remove contact cover and inspect contacts
