1st Time Power Up Procedure (or after a motor is replaced)
Caution: If full AC Voltage is applied and the motor connections are wrong, the control will be damaged. Apply 10% of the input voltage to test motor lead connections at the first time power up or after a motor is replaced.
It is strongly recommended that a Variac (AC Rheostat) be used for the first time power up procedure. If full AC power is applied to the control and the motor leads are incorrectly connected (wrong phase) the control will be damaged.
1.Using a Variac (AC Rheostat) apply 10% of the rated AC input voltage to the control.
2.Slowly turn the speedpot CW. Watch for erratic rotation or excessive source current. If either occurs, immediately return the speedpot fully CCW, and turn off the power.
3.Try another phase combination of P1 Φ1, Φ2 and Φ3.
There are six (6) combinations for connecting the three phase motor leads to P1 Φ1, Φ2 and Φ3.
4.Apply power and test again. One combination will work. The correct combination will allow smooth rotation of the motor, and the lowest current draw from the AC source.
5.Remove AC power.
6.Remove the Variac.
7.Connect normal AC input voltage at
8.Apply power and check for proper motor operation.
