Q7330A Adjustments (Fig. 8 and Table 4)

The Q7330A provides control interface for W936 and W945 

controllers. This module consists only of the terminal block 

and does not require any adjustments. See Fig. 8 for 

terminals.

After the motor stroke is adjusted (if necessary), simply plug 

the module onto the motor quick-connect terminals and 

secure to the motor. See Fig. 9 for typical system wiring.

To check proper motor operation:

1. Provide power to the motor.

2. Jumper terminals 1 and 2 to drive motor open (clock-

wise

 as viewed from power end).

3. Jumper terminals 1 and 3 to drive motor closed. Con-

nect field wiring to appropriate screw terminals.

1. Open terminals (+), (-), F

Motor closes fully ccw

Motor opens fully cw

2. Jumper F to (-)

Motor opens fully cw

Motor closes fully ccw

3. Remove either T terminal

Spring return motors return to normal spring position (fully ccw

 for 

mechanically normally closed motors, fully cw

 for mechanically normally 

open motors).
