(+) and (-) denotes terminals on the controller
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.
