MOTOR INSTALLATION AND CALIBRATION
____________________________________________________________________________________
2.
To calibrate the motor output, remove the black cover, declutch the gear train and
manually rotate the output clamp as follows:
On a two-way valve, rotate the clamp fully clockwise until the pointer stops
at the 90-degree position. Release the clutch pushbutton to engage the clamp
at that position.
On a three-way valve, note that the 90-degree rotation scale is divided into ten percent
graduations. Rotate the clamp clockwise until the pointer is midway between the
90-degree and adjacent graduation marks. Release the clutch to engage the clamp at that position.

3.
Apply moderate pressure to minimize the gap between the motor and safety shield, and tighten the two 10 mm hex nut to 150 lb. in.
torque. Use of a 6 pt deep well socket wrench is recommended.
Apply force gradually, as sudden, or impact force may damage the u-bolt.

4.
Remove the c-clamp installed during the motor removal procedure.

5.
Connect field wiring and re-start the control valve as instructed in pages 5-8. Remember to press the reset/auto-stroke push-button
before applying a control signal.
Important: A small phase error in re-clamping the motor without initiating an AUTOSTROKE CALIBRATION CYCLE will cause severe
damage to the motor by overrunning the cycle endpoints that were saved during the last AUTOSTROKE CALIBRATION CYCLE.
Do not press the RESET pushbutton within 10 seconds of applying power to the actuator (See page 8, INITIAL STARTUP AND OPERATION).
Pressing the RESET pushbutton within 10 seconds of applying power to the actuator may result in the actuator programming being
changed. If the actuator programming is changed, the actuator may not respond correctly to the control signal.

1.
Slide the motor output clamp over the linkage shaft; then install the anti-rotation screw, securing it with its locking nut.
The Anti-Rotation Screw to the Motor Tab should have some play. See Below.
An anti-rotation pin engages a slotted tab at
the foot of the motor to allow alignment of
the motor as its shaft clamp rotates. The pin
(screw) threads into a boss on the linkage
base and is retained by a locking nut. Note
that the slotted motor tab rests and moves
freely on the threads.
An anti-rotation pin engages a slotted tab
at the foot of the motor to allow alignment
of the motor as its shaft clamp rotates. The
pin (screw) passes through the “Hi-Temp
Motor Mounting Bracket, and is retained by
“KEP” nuts on either side of the sheet metal.
Note the positions of the parts and that the
slotted motor tab rests and moves freely on
the threads.
The Enerdrive energy must be dissipated before completing these steps. See Removing on AmurAct motor Step 3.
