Adjustment of the movement of vertical gates manufacturer Canada. Do-it-yourself sectional garage door adjustment

Every good owner knows that any mechanism, even the most reliable one, can break down. And to prevent unpleasant surprises, we recommend that you inspect your garage door mechanism at least once a month for possible problems.
The most common problem with garage doors during their constant use is the sagging of the cable, which is responsible for raising and lowering the garage door leaf. This is due to incorrect installation of the springs on the sectional doors.
First of all, we want to draw your attention to the fact that adjusting or replacing the cable of a sectional door is not a safe matter, since the torsion springs are under strong tension. Therefore, do this work with great care, and use only reliable and high-quality tools.
Here are the main stages of work:

1. Check the marking strip on the spring so that it is in the form of a straight strip.


2. Fix the sectional door so that it does not rise during the repair work.


3. Insert the tension rod into the hole where the spring ends and turn.


4. Do the same operation with another rod, but already pulling out the first one.


5. Secure the spring using the key.


6. Check operation of sectional doors.

Installation of the mechanism of the torsion spring of sectional doors Dorkhan is carried out according to a similar principle. If you still cannot adjust the tension of the cables of the sectional doors, then our advice is to contact qualified repairmen for services.

How to twist a spring on a torsion gate

Setting up the torsion springs of sectional garage doors on your own is quite simple. Even a beginner in repair will be able to understand how to tighten the torsion spring on the gate. The main thing is to follow all the necessary precautions and use only high-quality tools.
If you are interested in how to tension and fasten the cable on large garage doors, for example, manufactured by Dorkhan, then you must understand that the entire torsion shaft is assembled in parts. So, here is the basic plan for how to adjust the torsion gate mechanism:

1. Weaken the tension on the springs by lowering and fixing the structure.


2. Unscrew the screw, which will give the drum mechanism free movement.


3. You wind the rope.


4. Screw the screw back into its original position.

Many inexperienced workers are wondering: why do the cables fly out at the garage door? The answer to it lies precisely in the uncoordinated work of the entire mechanism and, in particular, the springs.

Figure 2: Main parameters of torsion springs

Automatic gate spring adjustment

Adjustment of cables on gates with one or several torsion bars, as well as other types of gates, is carried out in the following steps:

• Raise the gate and fix it with stands. In this way, we can reduce the pressure on the springs of the automatic gate.


• Using a screwdriver, unscrew the screw, which helps to fix the cable mechanism in the drum.


• Winds the rope to the optimum tension value.


• Screw the screw back.


• We start the gate and check the operation of the mechanism.

Figure 3: Spring Tension Steps

Spring tension adjustment on sectional doors

All repair work on sectional doors is carried out using the same method, but the adjustment of electric sectional door cables still has some peculiarities. Since such structures, in addition to all components, have electrical components. Therefore, before proceeding with installation or repair, for your safety, you should disconnect the wires from the electric drive for the duration of the work. Since accidentally touching the wires with a metal screwdriver can lead to electric shock.

The most important factor in the good and long-term operation of garage sectional doors is the tension of the cables. They are used to activate the work of the canvas, as well as to create a balance of the entire structure.

A person who has this type of gate on his site should in no case allow cables to sag, because this is the main and main mistake when using them.

Due to such inattention, in the future, you may encounter deformation of the guides and the leaf, the gate moves along the guides for opening and closing.

Adjusting sectional doors means adjusting the cables, but such a task cannot be called difficult. Each person will be able to cope with it with their own hands and not resort to the services of specialists. The main thing is to understand how it's done.

Work algorithm

First of all, it is necessary to capture and strengthen the brackets in the lower part of the structure, after which the dowel is installed on each section of the gate. Next, the drum is fixed, and the set screw must be tightened.

At the second stage, the shaft rotates until the moment when the traces of sagging completely disappear. To achieve the desired effect, a person will need to make one and a half to two turns of the springs. When the process is completed, each bolt is tightened on the tension tips.

This allows you to finally fix the spring, and the gate returns to the desired state.

If the described algorithm and the adjustment of the garage door made did not make it possible to get rid of the sagging, then it is necessary to use the principle of simultaneous rotation of the shafts.

Taking into account the fact that turning can be done using the design of the sleeve, initially each coupling bolt is released, and after that it is necessary to turn the shaft from which the negative process is observed. The second shaft must be stationary, it is important to observe this.

Exhibiting structures with a continuous shaft

If sectional garage doors are equipped with a continuous shaft, then the algorithm of work that needs to be performed will change somewhat in order for the adjustment to be successful.

1. The working panel rises, then in this position it must be fixed. This will be required in order for the tensioned cable to loosen a little.
2. The screw that secures the cable in the drum must be unscrewed.
3. Try to adjust the cable as much as you need to get rid of the slack. Try to reduce the size to the minimum mark.
4. At the next stage, the cable screw is tightened, with the help of which fixation is carried out.
5. The panel returns to its original position, believe me, did you manage to get rid of the sagging and whether both cables were equally tensioned.

If the adjustment of the garage door was successful, and the cable no longer sags with the help of springs, then you can safely leave the structure, because you managed to cope. If even a slight sag is observed, then the algorithm indicated above must be repeated.

Each cable should be evenly stretched, so do not overdo it by pulling one of them.

If in the future you happen to encounter again, and you need to adjust, then you can safely use the described methods. This will keep the garage door always in proper and working order.

Do not forget that even in the absence of slack, the tension of the cables will have to be checked from time to time.

This technique is for gates with a spring, torsion mechanism, which is located above the gate opening. For the correct and trouble-free operation of sectional doors, it is necessary to periodically carry out technical inspection and lubrication of moving parts.

In the absence of gate maintenance, safety elements, such as a photocell, sometimes there are cases when the gate runs into mechanical obstacles when lowering. Mechanical obstacles are any objects accidentally forgotten in the gate opening. The consequence of a collision, as a special case, is a different tension of the cables.

Possible typical manifestations of misalignment of sectional doors with a manual chain drive or motor:

1. the lift gate has stopped rising or falling;
2. there is a bias on one of the sides;
3. lifting is not carried out to the end;
4. the descent of the canvas is not carried out to the end.

Typical design of a torsion shaft assembly. Single-shaft balancing system for garage and industrial doors. Split shaft.

For normal operation of sectional doors, the cables must be taut. Sagging of cables of sectional doors is not allowed.

As a result, the balancing cables of sectional doors fly off or get tangled.

Let's try to figure out how to fix this problem.

You - got confused, flew off, the cables on the gate and rollers broke off, the brackets are in place. This technique is also applicable when the cables are skewed.

First of all, at the beginning of the adjustment, we unblock the engine (if the control is automatic), if it is a chain, we will unblock the chain.

We produce a complete weakening of the traction spring.

The next step is spring tension.

We turn to the elimination of sagging, this technique also applies when the gate cables break.

With a weakened spring, we had the opportunity to remove the lower thimble of the cable. Next, unravel the cable. Having untangled the cable, we throw the cable into the groove of the drum, at least 1/4 of the drum. Next, we lay the cable behind the rollers. We fasten the cable loop to the thimble, depending on the design of your gate.

We turn to the tension of the traction spring and eliminate the slack in the cables.

Turn the shaft until the cable slack is removed. To ensure the tension of the cables, it is necessary to wind the springs by 1.5 - 2 turns and fix them in this position by tightening the bolts of the tension lugs.

Elimination of uneven tension of the left and right cables.

If one of the cables still sags, the sagging is eliminated due to the mutual rotation of the shafts, which is ensured by the design of the coupling (the presence of slotted holes for the coupling screws).

.

To do this, loosen the coupling bolts, turn the shaft, on the side of which there is sagging, while holding the other shaft in its original position.

After removing the slack in the cable, tighten the coupling bolts of the coupling.

The next step is to fully cock the springs in accordance with the recommendation. The number of turns must be indicated on the nameplate of the gate.

The torsion spring is responsible for balancing the door leaf.

It distributes all the weight evenly, thus making it easier to lift the gate. Acts as a counterweight. The force of the spring is directed upwards, and the mass of the gate is directed downwards. The ideal setting of the door leaf is set according to the method recommended by the manufacturer. Data on the number of coils of spring tension is indicated in the product passport, on the nameplate of the door, available from the door supplier.

Check for correct spring tension.

The spring sags a little in the middle - this is its normal charged state. The number of marks on the skein must correspond to the number of revolutions indicated in the passport for the set.

Variants of the state of the torsion spring.

• Curved upward;
• wavy shape;
• smooth;

The external signs of the spring indicate that it is overtightened.

If during the operation of the gate clicks or rattles are heard from the side of the spring, the torsion mechanism must be lubricated with liquid lubricant, if the sound does not stop, a specialist should be called. Check the condition of the spring before changing the season, and especially after severe frosts, the spring should sag a little in the middle - the main recommendation

After adjusting the springs, it is necessary to check the correct adjustment of the sectional door balancing mechanism.

To do this, raise and then lower the sectional door by hand. The applied force should be 10-20 kg. The movement of the gate must stop when the force stops.

How to eliminate the uneven tension of the left and right cables with a non-split shaft.

What does it mean not a split shaft - it does not have a coupling. The consequence of the lack of detail is that the tension of the cables is adjusted not from the top, but from the bottom. The coupling, as described above, eliminates the uneven sagging of the left and right cables.

1.1. Wiring requirements when connecting a sectional door system.

Diagram 1 shows the cables needed to connect the various devices. Table 1 shows the minimum number and size of wires. Cable brands should be selected based on the method of laying communications.

Table 1. Types of cables.

Compound	Quantity and min. wire cross section	Maximum allowable
A: Flashing light with antenna	N°1 wire 2x0.5 sq. mm. N°1 50 ohm shielded cable (RG58 type)

2. Connecting external devices to the SPIN drive.(Scheme 2)

Before making electrical connections, make sure that the power supply is turned off.

Guided by Scheme 1 and Table 1, lay the necessary communications.

Make the connection according to Diagram 2.

		Description

	signal lamp	A signal lamp LUCY B or MLB (with lamp 12V, 21W) can be connected to this output. When performing a maneuver, the device will flash at intervals of 0.5 s.

3 Programming radio transmitters.

The SPIN control unit has a built-in radio receiver for remote control, operating at a frequency of 433.92 MHz and compatible with the following types of transmitters:

Each radio transmitter recognized by the receiver has its own unique code, which differs from the code of others by the transmitter. Thus, the learning procedure must be carried out for each transmitter. Radio transmitters can be registered in two modes. The most commonly used mode II is described below. Detailed information about the recording modes of radio transmitters is given in paragraph “4.5.1. Programming Radio Transmitters” complete instructions for SPIN11.

ModeII: In this mode, different transmitter buttons can be used to issue control commands as described in Table 3 to one device or to control different devices.

Programming Transmitters in Mode II(each button separately)

The programming function is available for the first 10 seconds. after energizing SPIN11. After turning on SPIN11, wait until the LEDs L1, L2, L3 turn off, then do the following:

1. Press the RADIO button as many times as necessary, according to the number of the selected command (see table 3)
2. Make sure that LED L1 flashes the required number of times, according to the command number (see table 3)
3. Press and hold the button on the remote control that needs to be registered in the receiver's memory to execute the selected command until the L1 LED flashes 3 times
4. Release the button on the remote

To assign the selected command to a new remote control, repeat the procedure from step #3. To assign a different command (see table 3) to the “current” or new remote control, repeat the procedure from step #1. If, when trying to write a remote control button, the L1 LED flashes 3 short times, it means that the code is already stored in the receiver's memory.

The programming process will end automatically if the next transmitters are not entered into the receiver's memory within 10 seconds. The light will flash once to indicate the end of the programming interval.

4 Recognition of the door travel end positions.

The control unit must recognize the open and closed gate positions. During the search procedure, the door leaf also moves between the opening and closing mechanical stops. Additionally, during this procedure, the configuration of the STOP input and the presence of devices connected to the inputs are determined and stored. PHOTO and Phototest.

1. Make sure that the drive belt is sufficiently tensioned (no slack in the belt) and that the mechanical stops are securely locked.

2. block carriage

3. Press the [??] and buttons and keep them pressed

4. Release the buttons as soon as the movement starts (after about 3s)

5. Wait until the control unit has finished searching for the end positions: closing, opening and reclosing the gate.

6. Press the button for a complete opening maneuver

7. Press the button to close

During this procedure, the control unit memorizes the force required to open and close the gate.

If at the end of the self-learning mode, the indicator LEDs L2 and L3 flash, this indicates an error has occurred, refer to the "7.6 Troubleshooting" section of the full manual.

It is important that maneuvers are not interrupted during the self-learning process, in particular by the STOP command.

If this still happened, you need to repeat the learning process again.

If the belt tension is not strong enough, during the end position search procedure, it may slip on the gear. If this situation occurs, press the button to abort the learning mode; tighten the belt and resume the mode from the beginning.

Self-learning of the motor in the end positions of opening and closing is possible only after the radio receiver has been programmed and not earlier than 10 seconds after power is supplied to SPIN11.

5. Preset functions.

The SPIN drive control unit has a number of programmable functions. If necessary, the functions can be changed through the programming procedure using three buttons and three light-indicating diodes (LEDs). The buttons can be used both for the programming procedure and for controlling the unit in test mode:

There are two programming modes:

Startup Programming: Before applying voltage to SPIN11, to activate the mode, press and hold [ Set] on the control unit.

Standard Programming: Activated by pressing and holding a button [ Set] at any time while power is applied to SPIN11.

For both modes, the available functions are divided into two levels:

Level 1 : functions set in ON/OFF mode (reciprocal of 2 possible values); in this case LEDs L1,L2 and L3 indicate the function (if the LED is on, the function is activated, if not, it is deactivated).

Level 2 : Parameters set on a value scale (from 1 to 3), in this case each LED L1,L2,L3 point to the current value of the parameter out of three possible.

5.1 Level 1 functions

Table 4: List of Functions Programmable in At Startup Mode
	Description	Example
	Variable sensitivity	This feature allows you to enable or disable variable obstacle detection sensitivity. Factory setting: variable sensitivity activated (LED L1 off): more sensitivity is realized with low motor force and less sensitivity with increased motor force. The function aims to provide optimal obstacle detection accuracy. Variable Sensitivity can be disabled, leaving three fixed levels of motor force active (LED L1 on)
	Phototest/Electromechanical lock	This function allows the user to activate output 8 on the board to work with the Phototest or Electromechanical lock function. Factory setting: output 8 activates the Phototest function (LED L2 off). The return value of the function programs the output to operate the SPIN11 with electric lock (LED L1 on)
	Partial opening	This function allows you to select a higher or lower partial opening height. The factory setting specifies a higher height (approx. 1m, LED L3 on). The reverse value of the function sets a lower partial opening height (approx. 15 cm, LED L3 off)

At the end of the procedure Programming "At startup", LEDs L1,L2 and L3 display the status of functions in "Standard Programming Mode".

Table 4a: List of functions programmed in Standard mode
	Description	Example
	Closing speed	The function allows you to select the motor speed during the closing manoeuvre, based on two levels: "high" and "low". The factory speed setting is "high" (LED L1 on). Inverse function value - speed "low" (LED L1 off)
	Opening speed	The function allows you to select the motor speed during the opening manoeuvre, based on two levels: "high" and "low". The factory speed setting is "high" (LED L2 on). Inverse value of the function speed "low" (LED L2 off)
	Automatic closing	The function allows you to activate the function of automatic closing of the gate after a certain period of time; the default pause time is 30 seconds, but can be changed to 15 or 60 seconds. Factory setting of the operating mode - "Semi-automatic" - automatic closing deactivated (LED L3 off)

During normal SPIN operation, the LEDs L1,L2 and L3 are lit or off depending on the status of their associated Standard Programming feature. For example, SID L3 will light up if the function "Auto close" activated.
