Adjusting the movement of vertical gates manufacturer canada. DIY sectional garage door adjustment

Every good owner knows that any mechanism, even the most reliable one, can break. And in order 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 in garage doors during continuous operation is the sagging of the cable, which is responsible for raising and lowering the garage door. This is due to incorrect installation of the springs on the sectional door.
First of all, we would like to draw your attention to the fact that adjusting or replacing a sectional door cable is an unsafe business, since the torsion springs are under strong stress. Therefore, do this work with great care and use only reliable and quality tools.
Here are the main stages of work:

1. Check the label strip on the spring for a straight strip.


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


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


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


5. Secure the spring using the key.


6. Check the operation of the sectional door.

The installation of the torsion spring mechanism for Dorhan sectional doors is carried out according to a similar principle. If you still fail to adjust the tension of the sectional door cables, then our advice is to contact qualified repairmen for services.

How to twist a spring on a torsion gate

Adjusting 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 observe all necessary precautions and use only quality tools.
If you are interested in how to pull and fasten the cable on a large garage door, for example, manufactured by Dorhan, then you should 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. Relax the tension on the springs by lowering and securing the structure.


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


3. Reeling in the rope.


4. Screw in the screw to its original position.

Many inexperienced workers ask themselves the question: 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, of the springs.

Figure 2: Basic parameters of torsion springs

Automatic gate springs adjustment

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

• We raise the gate and fix it with stands. Thus, we can reduce the pressure on the springs of the automatic gate.


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


• Coils the rope to the optimum tension.


• We turn the screw back.


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

Figure 3: Stages of Spring Tension

Adjusting the spring tension on sectional doors

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

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

A person who has this type of gate on his site should in no case allow the 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 curtain, the gate moves along the guides for opening and closing.

Adjusting a sectional door means precisely 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 this is done.

Work algorithm

First of all, it is necessary to grab and strengthen the brackets at the bottom of the structure, after which a key 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 turns until 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 over, each bolt is tightened on the tension lugs.

This allows the spring to be finally fixed, and the gate returns to the required state.

If the described algorithm and the adjustment of the garage doors made it impossible to get rid of the sagging, then it is necessary to use the principle of simultaneous turning of the shafts.

Taking into account that the turning can be done using the muffra design, initially each tie bolt is dissolved, 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.

Exposure of structures with continuous shaft

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

1. The working panel rises, then it must be fixed in this position. This is required in order for the tensioned cable to loosen a little.
2. The screw that fixes 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 dimensions to the minimum mark.
4. In the next step, the cable screw is tightened, with the help of which the fixation is carried out.
5. The panel returns to its original position, believe me, did you manage to get rid of the sagging and did you manage to pull both cables equally.

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 there is even a slight slack, then the above algorithm must be repeated.

Each cable should stretch evenly, so don't overdo it by pulling one of them.

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

Do not forget that even if there is no slack, the tension of the cables will have to be checked from time to time.

This technique is for doors with a spring, torsion mechanism, which is located above the door opening. For correct and trouble-free operation of sectional doors, it is necessary to periodically inspect and lubricate the moving parts.

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

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

1. the lifting gate has stopped rising or falling;
2. there is a skew to one of the sides;
3. the rise is not fully carried out;
4. the descent of the canvas is not fully carried out.

Typical torsion shaft assembly. Single-shaft balancing system for garage and industrial doors. The shaft is split.

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

As a result, the balancing cables of the sectional doors fly off or become entangled.

Let's try to figure out how to adjust this nuisance.

At you - the cables on the gate and rollers are tangled, fell off, the cables on the gate and the rollers are broken, 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 the control is chain, we unblock the chain.

We make a complete weakening of the traction spring.

The next step is tensioning the spring.

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

With a weakened spring, we have the opportunity to remove the lower edge of the cable. Next, we 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 attach the loop of the cable to the thimble, depending on the design of your gate.

We turn to tensioning the traction spring and eliminating the sagging of the cables.

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

Elimination of uneven tension on 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 (by the presence of groove holes for the tie screws).

.

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

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

The next step is to fully charge the springs in accordance with the recommendation. The number of turns must be indicated on the door plate.

The torsion spring is responsible for balancing the door leaf.

It distributes all weight evenly, thus making it easier to lift the gate. Serves 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. The data on the number of spring tension turns is indicated in the product passport, on the door plate, available from the door supplier.

Checking the correct spring tension.

The spring sags slightly in the middle - this is its normal charged state. The number of marks on the skein must correspond to the number of turns indicated in the passport for the kit.

Torsion spring state options.

• Curved upward;
• wavy shape;
• smooth;

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

If during door operation you hear clicks or rattling from the side of the spring, the torsion mechanism must be lubricated with liquid grease, if the sound has not stopped, call a specialist. 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 setting of the sectional door balancing mechanism.

To do this, lift 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.

That does not mean 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 connecting sleeve, as shown above, eliminates the uneven sagging of the left and right cables.

2. Connecting external devices to the SPIN series drive.(Diagram 2)

Before making electrical connections, make sure the power is disconnected.

Using Scheme 1 and Table 1, lay the necessary communications.

Connect according to Diagram 2.

		Description
		Input for connecting a radio receiver antenna. The LUCY B lamp has a built-in antenna. As an alternative to an external antenna, a piece of wire connected to the signal terminal can be used.
	Step by step	Input for motion control devices. It is possible to connect "normally open" devices to the input.
		Input for devices that block or stop the execution of the maneuver. Contacts can be connected to the input: "normally closed", "normally open" or a device with constant resistance.
		Input for safety devices such as photocells. A break in the chain during closing causes a stop and a change in direction. Contacts "Normally closed"
	Phototest	Before starting each maneuver, a functional check of all connected safety devices is carried out. The function is active with a specific connection method; Refer to section "7.3.2 Photocells" for full instructions for additional connection information
	Signal lamp	A signal lamp LUCY B or MLB (with a lamp 12V, 21W) can be connected to this output. When performing a maneuver, the device will flash at 0.5 second intervals.

3 Programming radio transmitters.

The SPIN control unit has a built-in radio receiver for remote control, operating at 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 memorization 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 on the recording modes of radio transmitters is given in paragraph “4.5.1. Programming radio transmitters ”of the complete instructions on SPIN11.

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

Mode II Transmitter Programming (each button separately)

The programming function is available for the first 10 seconds. after powering up SPIN11. After turning on the SPIN11, wait until the LEDs L1, L2, L3 go out, then do the following:

1. Press the RADIO button the required number of times, in accordance with 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, which must be registered in the receiver's memory to execute the selected command until the L1 LED flashes 3 times
4. Release the remote button

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

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

4 Recognition of the end positions of the door travel.

The control unit must recognize the positions of the open and closed gate. During the search procedure, the door leaf also moves between the mechanical stops for opening and closing. 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 the drive belt is sufficiently tensioned (no slack in the belt) and the mechanical stops are securely locked.

2. Block carriage

3. Press and hold the [??] buttons

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

5. Wait until the control unit finishes searching for the end positions: closing, opening and closing 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 effort required to open and close the gate.

If at the end of the self-learning mode LEDs L2 and L3 are blinking, this indicates an error has occurred, refer to "7.6 Troubleshooting" for the complete instructions.

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

If this does happen, you need to repeat the learning process again.

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

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

5. Specified 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 LEDs. The buttons can be used both for programming procedure and for controlling the unit in test mode:

There are two programming modes:

Start-up programming: Before energizing SPIN11, to activate the mode, press and hold [ Set]on the control unit.

Standard programming: Activated by pressing and holding the button [ Set]at any time with power on to SPIN11.

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

Level 1: functions set in ON / OFF mode (reverse value of 2 possible); in this case the LEDs L1,L2and L3 indicate the function (if the LED is on, the function is activated, if not, it is deactivated).

Level 2: parameters adjustable on a scale of values \u200b\u200b(1 to 3), in this case each LED L1,L2,L3indicate the current value of the parameter out of three possible.

5.1 Level 1 functions

Table 4: List of Functions Programmable in Startup Mode
	Description	Example
	Variable sensitivity	This function allows you to enable or disable the variable sensitivity of obstacle detection. 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 detection accuracy. Variable sensitivity can be deactivated, leaving the three fixed motor force levels active (LED L1 on)
	Phototest / Electromechanical lock	This function allows the user to activate output 8 on the board to work with the Phototest function or the Electromechanical lock. Factory setting: output 8 activates the Phototest function (LED L2 off). The inverse value of the function programs the output for operation SPIN11 with an electric lock (LED L1 is on)
	Partial opening	This function allows you to select a higher or lower partial opening height. The factory setting determines a higher altitude (approx. 1m, LED L3 is on). The inverse 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,L2and L3display the status of the functions in the "Standard Programming Mode".

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

During normal SPIN operation, the LEDs L1,L2and L3 on or off, depending on the status of their associated Standard Programming feature. For example LED L3 will light up if the function "Automatic closing" activated.
