The dimensions of the PROTECO Strike-5 mechanism are convenient, and in most cases, the available space is sufficient.

Choosing a sliding gate mechanism

• The weight of the sliding gate. The PROTECO Strike-5 mechanism is suitable for gates weighing up to 500kg.

A gate weight of 500kg covers most gate cases, as an average fence gate weighs 50-60 kg/m. The point where special attention should be paid is that the gate should operate smoothly in manual mode. This means that we test the gate's movement without the mechanism or with the mechanism in manual operation. If the gate does not operate smoothly, it should be repaired. Otherwise, it will cause problems for the mechanism and there will be failures.

 

Sliding gate - Checks before mechanism installation

The most important check that needs to be done even before ordering the mechanism is to verify that the gate operates smoothly by hand. We open and close the gate at a steady speed, approximately the same speed it would have with the mechanism. If at any point the movement presents difficulty, there is any shaking, etc., the gate must be repaired before the mechanism is installed.

The checks that need to be carried out in detail are:

• If the rail is straight without curves, dents, and rust. It must also be properly secured to the ground.
• The gate wheels must be in good condition. They should not show signs of deformation or rust. Their rolling must be trouble-free.
• Just before the gate's closed position, we check the gate's oscillation. If it moves intensely back and forth, we must intervene and repair the gate. Possible repair points are the gate's construction material (too flexible), the position where the rollers are placed (they have a large gap with the gate), or the roller mounting point is quite flexible.
• The gate must smoothly enter the receptacle at the closed position. It must "lock" so that it is not easy to lift it with a crowbar.
• The open and closed positions of the gate must be defined by mechanical stops. Under no circumstances should the leaf be free to pass the closed or open position.

Typical sliding gate arrangement with mechanism

 

 In the above sketch, we observe a typical arrangement of a sliding garage door with a mechanism. Obviously, the main element of the construction is the gate leaf, which can be made of aluminum, metal, or wood. A basic prerequisite is that it must be sturdy and rigid enough to be able to move, while only touching the wheels and rollers, without excessive oscillation.

The gate must have mechanical stops to define the closed and open positions. The mechanical stops define the gate's travel.

The rollers are placed in such a way as to be in contact with the door leaf throughout its travel (from the fully open to the fully closed position). Essentially, the rollers keep the door perpendicular to the ground. A basic prerequisite is that they do not hinder the door's movement.

The gate rests on wheels, which allow it to move. The movement occurs on the rail, which has a shape that allows it to work perfectly with the wheels. The wheels must be in good condition without signs of deformation or rust. The rail must be properly supported on the ground, be straight, and not show bumps or deformations.

The motor is also positioned so that it is always in contact with the gate. The movement is transmitted to the gate by the motor's gear. The rack, which is a toothed bar, is mounted on the gate. The rack is the point of contact between the gate and the motor, and through it, the movement is transmitted.

Photocells are the most important accessory of a sliding garage door with a mechanism. They prevent accidents and protect both users and their vehicles. They are installed at the gate opening and prevent the sliding gate from closing when there is an obstacle in its path.

Another accessory for a sliding garage door (not shown in the sketch) is the warning light. It is placed in a prominent position to warn passing vehicles and pedestrians that the garage door is operating. It is a particularly useful device when the garage door is adjacent to a busy road or when visibility is not optimal.

 

Wiring of PROTECO Strike-5 sliding gate mechanism

 

 

Wiring sliding mechanisms is a process that usually requires specialized personnel.

• The mechanism requires a 3x1.5mm² or 3x2.5mm² cable if the installation point of the automation is far from the control panel. (It is good practice for the mechanism to have a separate fuse in the control panel)
• Wired photocells require a 4×0.6mm² cable for the receiver and a 2×0.6mm² cable for the transmitter. Usually, we place the receiver near the mechanism. If it is impossible to run a cable across for the photocells, we can install reflector photocells, which only require wiring on one side.
• The warning light requires 1×1.0 mm² or 2×1.0 mm² wiring. (can be added separately from the set)
• The key switch or simple push button requires 2×0.6mm² wiring. (can be added separately from the set)

All cables must be protected from weather conditions (inside conduits).

Safety Photocells - Operation

Safety photocells are an economical but essential accessory for any type of garage door. They prevent accidents and do not require maintenance or special care from the user.

Safety photocells consist of a transmitter and a receiver. The transmitter emits an infrared light beam, in the non-visible spectrum, which is directed towards the receiver. When there is no obstacle to interrupt the beam, the door operates normally. When the beam is interrupted by an obstacle (vehicle, pedestrian, pet, etc.) during the closing of the door, the control panel instructs the mechanism to stop the closing of the door and start the reverse movement (opening). If the beam is interrupted while the door is opening, it continues its course normally, and if it is open, it is not allowed to start closing.

In case it is not possible to run cables for wired photocells, we can choose the solution of photocells with a reflector. These photocells only require wiring on one side of the door (the motor side) so they are easier to install. They are preferred in cases where the door and the surrounding area have been completed without provision for wiring. They incur a small additional cost compared to wired photocells but are a good solution when wiring cannot be run. In the set, you can add either wired photocells or reflector photocells.

Wired photocells NOLOGO IR5001P / Zoom-Z2E

The NOLOGO IR5001P / Zoom-Z2E photocells are a reliable choice of wired photocells consisting of a transmitter and receiver and have a range of 20m. As wired photocells, they require wiring on both sides of the opening.

 

Technical specifications of NOLOGO IR5001P / Zoom-Z2E photocells:

• Operating voltage: 12 or 24 V DC, 12 or 24 V AC
• Maximum operating distance: 20m
• Maximum switch contact current: 0.5 A at 48 V AC/DC
• Transmitter operating current: 25 mA
• Receiver operating current: 35 mA
• Interference rejection circuit from other light sources
• Automatic focusing

They are usually installed at a height of 50cm from the ground. They are simple to install and can prevent major damage and accidents. Their operation is trouble-free as they require no maintenance, are not affected by weather conditions, and do not require any action from the user during their use.

 

Safety photocells with reflector Witt Sensoric RP25

The greatest advantage of reflector photocells is that they only require wiring on one side, where the transceiver is installed. The reflector is placed opposite. The reflector has dimensions of 10x10cm, while the transceiver dimensions are:

 

 Features of Witt Sensoric RP25 safety photocells with reflector:

• Convenient size and shape for both the transceiver and the reflector.
• Do not require batteries like other competing wireless photocells.
• Reliable operation even in bad weather conditions (suitable for outdoor use).
• Range of 15m, covering the majority of sliding doors.
• Not interfered with by sunlight or other light sources, as they operate with a polarized light filter. This means they can even detect reflective objects between the transceiver and the reflector, so it is not easy to fool them with the polished surface of a car.
