Manual Operation

Set the AUTO/MAN switch in the MAN position.

Connect ground to the screw located below the shaft release button.

Connect neutral to terminal N.

Only terminal "L" must be powered to enable manual operation. The actuator can

now be driven to the maximum (high fire) position (switch cam I) or the fully closed

"economy position" (switch cam II) by using the toggle switch located to the left of

the AUTO/MAN switch.

Automatic Operation

1. Set the AUTO/MAN switch in the AUTO position.

2. Connect ground to the screw located below the shaft release button.

3. Connect neutral to terminal N.

4. Connect line voltage at all times to terminal L to provide power to the electronic

circuit board.

5. Connect line voltage to terminal L1 to provide power when modulating. Connect line

voltage to terminal L1 only after removing power on terminals A and Z (otherwise

actuator damage may result).

6. Connect line voltage to terminal A to drive the actuator to the maximum (high fire

purge) position. Once the maximum position is reached, terminal 11 (on switch I)

will be energized to provide position feedback.

7. Connect power to terminal ZL to drive the actuator to the minimum (low-fire)

position. Once the minimum position is reached, terminal 23 (on switch III) will be

energized to provide position feedback. Adjustment of switch III will determine the

low-fire stop position. Switch III (low fire) must be set at a higher position than

switch II (fully closed). Terminal ZL may be energized only after removing power

from terminals A, Z, 13, and LR.

8. Connect line voltage to terminal Z to drive the actuator to the fully closed/economy

position (switch II).

9. Connect the input control signal wires to the appropriate terminals. See Figure 11.

CAUTION:

Do not power terminals A and Z simultaneously. Actuator damage will

occur.
