GENERAL START UP OPERATION

Voltage Check—
1. Put the HAND-OFF-AUTO Selector Switch in the "OFF" Position.
2. Energize the incoming power feeder.
3. Measure the line voltage at L1, L2 and L3 at the top of the disconnect switch. Confi rm that the
measured voltage matches the voltage on the data plate.
Motor Rotation–
1. Close the enclosure door.
2. Quickly turn the HAND-OFF-AUTO Selector Switch to the "HAND" position then back to "OFF"
position. This will "bump" the jockey pump motor - observe the rotation of the motor to confi rm
it is rotating in the proper direction. If motor rotation is incorrect, turn off jockey disconnecting
means, open door, and switch position of any two of the connected motor leads. Repeat this step
to confi rm proper rotation.
Controller Operation–
Each controller has a HAND-OFF-AUTO selector switch for selection of Manual or Automatic opera-
tion. When placed in HAND, the motor starter is energized and the motor will run until the switch
is placed in OFF. When the switch is placed in AUTO, the motor starter is energized by the XG Pump
Controller when the pressure reaches the "start" pressure setting. The motor stops depending on
the timer settings in the XG Pump Controller.
Before placing controller in service, leave the HAND-OFF-AUTO switch in the "OFF" position. Follow
the Programming Instructions included in this manual to set required pressure, timer and alarm
settings. Place the selector switch in the "AUTO" position. If system pressure is below the "start"
pressure setting, the pump will start.
NOTE: The "STOP" pressure setting must be set at a pressure less than the jockey pump "churn" pres-
sure (including minimum suction pressure), otherwise the pump will run continuously once started.
