manual operation, set down carrier rod and turn opening adjustment shaft of
counter clockwise to make cam return to the position shown in Fig.5. And then,
according to the adjustment amount, go on turning the shaft for more turns
clockwise, so as to provide the counter enough adjustment amount. Now turn and
lift carrier rod again and go on with item e.

Upon completion of stroke adjustment, turn and lift carrier rod of counter and
confirm the adjustment. Otherwise, once the electric actuator is in electric mode,
the counter will be out of action; the stroke control will go wrong; the electric
actuator will get into dangerous condition.
6.4 Adjustment for position indication mechanism
a. Setting for the pointer: close the valve before adjusting the stroke mechanism.
Now loosen the fastening screw on pointer and turn the pointer at 0 on the scale, and
then fasten the screw.
b. Potentiometer position setting: when the valve is closed, fasten the fastening
screw on potentiometer gear. With potentiometer gear threw out of mesh with final
pinion, turn the potentiometer until it reaches the end position corresponding to the
valve (The direction must be correct.) and return a little. Loosen the fastening screw
on potentiometer gear, push the gear to make it mesh with the final pinion and fasten
the fastening screw on potentiometer gear. Now the setting of position indication
mechanism is completed.
The setting of the above two steps can also be performed together with the setting
of stroke control.

Cautions
a. Pay attention to the determination of potentiometer rotation direction, as wrong
rotation direction will damage the part. When facing the pointer, the rotation direction
(for opening or closing) of potentiometer should be the same as that of the pointer (for
opening or closing).
b. When the position indicating mechanism is T-MDPI, the sliding gears must not be
meshed with two sets of gears at the same time. Otherwise, the mechanism may be
damaged!(See Fig.4)
c. When the position indicating mechanism is T-MDPI, the gear position of the
adjustment and positioning of sliding gear should be not less than and close to the
required number of turns! (See Fig.4)
6.5 About the local control mechanism
★
For basic type and explosion-proof type of electric actuator, the local control
mechanism is mechanical buttons which are on the control box cover. When local
control is needed, user needs to switch the control mode to local control and then,
push the open or close button according to user’s need. Push any button successively,
the electric actuator would operate the opening process or closing process; when user
leaves his grip on the button, button will automatically back again and actuator will
also stop operating.(Please switch control mode into remote control while local
control is finished.)
★
For the integral type and explosion-proof, integral type of electric actuator, its
