5.3.5 Cable should be set up correctly to avoid the rain leaking into the electric
actuator (In Fig.3, the first two connection patterns are right.)
6. Debugging
Cautions before debugging:
★
The maximum control torque had been set up and sealed off with torque plate for
the products before delivery. There is no need for users to make any adjustment of
torque control mechanism.
★
To facilitate user’s adjustment, the stroke control mechanism and position
indication mechanism are normally set to the following state before delivery:
a. The central gear in the driven units should align with the counter’s gear.
b. The potentiometer pinion in position indication mechanism and final pinion of
selective gears are in demising state.
c. Openness pointer is in middle position on the scale.
d. If the position indicating mechanism is T-MDPI, the initial position of the slip
gear is in the minimum turns position. The user needs to move the slide gear to the
corresponding gear range in the digital bar and fasten it firmly according to the actual
number of turns.(See Fig 4)
6.1Primary stroke adjustment
Manually operate the valve to make it be in an optional position of the whole stroke.
Turn on the power and operate the electric actuator for a short time to check, in the
itching type, if the rotating direction is the same as the valve. If not, change and
correct the phase sequence of power before performing the following adjustment.
a. Operate the valve manually to a point where there is only one thread distance from
the closing position.
b. Rotate the counter rod 90
°
to let it be unscrewed, so as to make the central gear to
disengage and one-digit gear of counter from the engaging state.
c. Clockwise turn closing adjustment shaft of counter to make cam touch closing
microswitch (a click is heard).
d. Unscrew the carrier rod of the counter 90
°
to make the central gear and one-digit
gear of the counter be in proper meshing state. (Turn the adjustment shaft a little to
check for the meshing, if the meshing is correct the adjustment shaft will not rotate.)
Now the closing position has been primarily adjusted.
e. Manually operate the valve to full open position. (Note: Do not screw down the
carrier rod of the counter in the process.)
f. In the full open position of the valve set down the carrier rod of counter, make
central gear throw out of mesh with one-digit gear of the counter.
g. Turn the opening adjustment shaft of counter counterclockwise to make cam touch
opening microswitch (a click is heard).
h. Unscrew the carrier rod of the counter 90
°
to make the central gear and one-digit
gear of the counter be in proper meshing state. (Turn the adjustment shaft a little to
check for the meshing, if the meshing is correct the adjustment shaft will not rotate.)
Now the closing position has been primarily adjusted.
