SERIES 90 MODUTROL IV™ MOTORS

CHECKOUT

After the installation and linkage adjustment, check the entire motor and control hookup. Proper checkout ensures that:

•The motor operates the load (damper or valve) properly.

•The motor responds properly to the controller as the input varies. See Table 6.

•The auxiliary switch, if used, operates at the desired point of motor rotation.

1.Inspect motor, linkage, and valve or damper to ensure all mechanical connections are correct and secure.

NOTE: In damper installations, the pushrod should not extend more than a few inches past the ball joints.

2.Ensure that there is adequate clearance for the linkage throughout the entire motor stroke without binding or striking other objects.

3.Ensure the motor transformer is properly sized.

NOTE: If a common transformer is used to power multiple motors, ensure the power input is in phase with all motors.

4.Drive the motor fully open and fully closed. See Table 6.

NOTE: Refer to controller or system instructions for additional checkout procedures.

REPLACEMENT

Damper Application

1.Turn off power and remove wiring from the old motor.

2.Remove the crank arm from shaft of old motor and remove the old motor.

3.Determine necessity of the mounting bracket. If the linkage can reach the new motor shaft position and the crank arm has clearance for the necessary rotation, the bracket is not required. Use the 220738A Adapter Bracket or the 221455A Crank Arm if the crank arm must rotate through the bottom plane of the motor.

a.If no bracket is required, mount the new motor directly to the equipment and refer to the Installation, Settings and Adjustments, and the Operation and Checkout sections of these instructions.

b.If the bracket is required, refer to the Adapter Bracket section and Fig. 3 in addition to the Installation, Settings and Adjustments, and the Operation and Checkout sections of these instructions.

4.Use No. 12 or 1/4 inch machine screws or bolts to mount the new motor.

5.Mount damper crank arm and linkage to the new motor shaft.

6.Use the Checkout procedures to test the crank arm and linkage adjustment.

5.For spring return motors, ensure that the valve or damper returns to normal position upon power interruption.

6.Return the controller to the desired setting before leaving the job.

Valve Application

When replacing a motor in a valve application, the linkage determines the necessity of the 220738A Adapter Bracket. With Q100, Q601 or Q618 Linkages, it is necessary to use the 220738A to raise the motor shaft to the appropriate height. Valve applications with a Q5001 Linkage do not require the 220738A Adapter Bracket. To operate Honeywell V5011 two- way or V5013 three-way valves through full stroke, use a 160° stroke motor.
