Installation Guide of Industrial Door Operator
The industrial door operator is mainly used in the industrial sectional door equipped with
balance spring, but also can applied in lifting industrial door. The installation of door
machine has two forms, shaft drive and chain drive. The factory standard configuration is
shaft drive. If user want to adopt chain drive installation, they can choose the appropriate
combination of sprocket chain according to the installation needs.
Shaft Drive Installation Chain Drive Installation
1) Check the door
After the door is installed, adjust the torsion spring, manually opening or closing the door
should be flexible and run without stagnation, observe the direction of rotation of the rope
sheave which should be consistent with the direction of opening and closing of industrial
door operator.

2) Determine the installation position
Consider the boundary dimension and installation direction of the door machine,
determine the position of the mounting bracket, mark the insert cavity position, drill the
screw hole and fix the mounting bracket. (The mounting bracket can be fixed inside and
outside the door machine, recommended to be installed inside, for the convenience of
disassembly of door machine).
3)Try to install industrial door operator
Install a fixing sleeve on door shaft in advance, and insert the industrial door operator into
the door shaft.
4) Pre-fixing industrial door operator
Fix the industrial door operator on mounting bracket by 4 pieces of hexagon head flange
bolts M10×20, do not tighten.

5) Find the direction of key slot
First pull the red handle A to the bottom to make the hand-pulled chain mechanism enga
ge with the main engine (Manual control mode).
Rotate the output shaft of industrial door operator by pulling the hand-pulled chain up and
down until the key slot of the output shaft is fully aligned with the key slot of the door
shaft.
6) Mount flat key and fixing sleeve
Mount the flat key, keep two fixing sleeves close to the two ends of the output shaft,
fasten the two M6 head screws in the key slot of door shaft in order to prevent the flat key
from loosening and falling off.
7) Tighten the screws, prepare wiring and debugging Tighten all screws.
Finally pull green handle B to the bottom to make the hand-pulled chain mechanism deta
ch from the main machine (Electric control mode).

Usage of hand-pulled chain
When you need to manually open or close the industrial door, then hand-pulled chain
would be required.
Before pulling the chain, please fully pull the red handle A in the hand-pulled chain
mechanism to make it engage with the main machine. The protection switch inside the
hand-pulled chain mechanism will automatically cut off the power supply. At this time,
the chain can be pulled.
The chain should be pulled continuously and evenly to avoid damage to the
hand-pulled chain mechanism.
When you need to electrically open or close the industrial door, please fully pull the
green handle B in the hand-pulled mechanism first to make it disengage from the
main machine, and the protection switch in the hand- pulled mechanism will be reset
to make the industrial door operator return to its normal electric operation. Please fix
the hand-pulled chain on the wall properly when it’s not in use
Note: 1. After using the chain. If the display screen on the control unit shows it
is hand-pulled chain operation, then under which the door cannot be opened or
closed electrically, because the protection switch inside the hand-pulled chain
mechanism has not been reset. To fully pull the green handle in the hand-pulled
chain mechanism to separate it from the main machine, the control unit will
work normally until the hand-pulled chain operation is not shown any more on
the display screen
2. The hand-pulled chain can only be used in special circumstances such as
power failure. It cannot be used long term as normal state.
Note: Check once a month whether the travel of opening or closing is changed,
whether the limit position is accurate and reliable, whether the door is well
balanced, if not, please make adjustment timely.
If necessary, please ask professional personnel for maintenance and
debugging.

Setting and Adjustment of Limit
Limit Switch Structure:
①Passive Signal Cam (GREEN)
② ③ Open Limit Cam (GREEN)
④ ⑤ Close Limit Cam (RED)
⑥Passive Signal Micro switch
⑦ ⑧ Open Signal Micro switch (N.C.)
⑨ ⑩ Close Signal Micro switch (N.C.)
1) Close Limit Setting
Electronically close the door to the close limit position, and press the "STOP" button
on the control box to stop the
door. During the closing of door,
observe the rotation direction of
red cam on the limit gear (see below).
After the door is stopped, make
the two red cams continue to rotate
in this direction by hand until
both red cams pin down the limit
switch, which will make cracking sounds,
and then tighten the head screw in the middle of copper nut by hex wrench to fix two
red cams.
2) Open Limit Setting
With the same way of close limit setting, fix the two green cams of open limit to the
desired open limit position.
3) Precise Adjustment of Limit
Test the industrial door operator. If open or close limit position is not ideal, open or close limit
can be adjusted precisely.
a. Precise Adjustment of Close Limit:
Rotate the micrometer adjusting screw of
two red cams clockwise or counterclockwise
(as shown in the right), and observe the
direction of movement of the cam. When
the direction of movement is consistent

with the original cam rotation direction,
the close limit switch moves up and the close position will be higher. Otherwise
close position will be lower; under normal circumstances, if the hex wrench is rotated
90 °, the close position will differ by around 25mm.
b. Precise Adjustment of Open Limit: With the same way, rotate the micrometer
adjusting screw of two green cams until the desired open limit position is reached.
Note:
1) During debugging of door operator, please use the buttons on the control
box for operation.
2) Test several times to ensure the normal opening or closing of door, and
control box should be installed in the wall or column of 1.4 meters where the
operation of door can be observed, and to prevent children from inadvertently
touching.

Setting and Debugging of Control Box
After confirming the wiring, turn on the power for the debugging of next step (the
following debugging steps can be applied to both single phase and three phases
control box):
a. Remote control learning:
①Press the black button AN1 on the circuit
board, LED2 indicator light flickers, then
press any button of transmitter (usually
Button 1), LED2 indicator light flickers again,
and then press the same button of transmitter,
LED2 indicator light will be strobe for 4 seconds and later off. The learning of the
remote control is finished.
②As for the learning of the other remote control, repeat the above steps. The same
control panel can learn up to 25 remote controls.
③There are two modes for remote control: Three Button Mode and Single
Button Mode. Please decide one of the two modes mode when ordering.
Three button mode remote control: OPEN/CLOSE/STOP of main engine are controlled by
three buttons separately on the remote control.
Single button mode remote control: OPEN/ STOP/CLOSE of main engine are controlled by
one button circularly on the remote control.
Note:
Three button mode remote control: As long as the "Button 1" is learnt, the entire remote
control learning can be completed.
Single button mode remote control:The four buttons on the remote control can be paired
to four different motors, each button for one motor.
