r-tec Sliding Gate Motors

Overview

A villa garden gate and a factory main entrance present very different loads, so r-tec sliding (rail) gate motors do not stretch a single family across that range — they split it into three voltage segments:

• 24 V DC — Light garden and villa gate (500 – 1,200 kg). In scenarios where battery backup is mandatory/recommended (villas where power outages are critical, secured estates).
• 220 V AC — Medium-segment estate and plaza entrances (1,000 – 2,000 kg). The most common use segment; wide variants with KING + SL series.
• 380 V three-phase — Industrial facility, factory and logistics terminal main entrances (2,500 – 4,000 kg).

Despite the segment split, the accessory side stays uniform: thanks to r-tec’s modular control board design, all motor series share the same accessory set (G24 board, RF433 receiver, photocell, flasher, remote), which keeps the dealer stock strategy simple.

Voltage segment selection

Segment	Max. door weight	Typical application	Mains requirement
24 V DC	500 – 1,200 kg	Residential, villa, small estate	230 V → board → 24 V output
220 V AC	1,000 – 2,000 kg	Estate, plaza, office campus	220 V single-phase
380 V three-phase	2,500 – 4,000 kg	Industrial, logistics, OSB	380 V three-phase

Reason to choose 24 V — Battery-backed system is possible; the gate operates during power outage. Also, 24 V is safer on the site by contact in terms of safety.

220 V series — warnings

CAUTION! Set the electronic brake adjustment trimpot according to your door’s weight. The door should stop when it reaches the limit switch; should not move backwards after stopping.

In the 220 V AC series AC motors, thermal protection + current control work together; in case of overload the board shuts itself down and notifies the site of the error before closing.

24 V series — warnings

Caution! Set the motor power adjustment trimpot (T1) according to your door’s weight. High power on a light door damages the connection set; low power on a heavy door causes the motor to stop before reaching the limit switch.

The 24 V DC series is suitable for battery operation; the battery charging terminal (62-63) is standard on the G24 control board.

380 V series

In three-phase supply, phase sequence and protection boards must comply with the technical PDF schematics. On wrong phase sequence the motor turns in the reverse direction — correction = swapping two phases in the field. In three-phase installations, use with the I-380 industrial control board r-tec I-380 is recommended.

Field discipline (common)

• Rail parallelism — Side rail and upper guide must be adjusted to millimetric precision; deviation causes the motor thermal protection to trip.
• Wheel quality — Double-bearing, stainless steel wheels are preferred; plastic wheels wear out in 2-3 years.
• Limit switch location — A 5-10 cm safety buffer must be left at the opening and closing ends.
• Brake adjustment — T2 (closing high speed) and T3 (deceleration) trimpots are adjusted with site trial.
• Periodic maintenance — Every 12 months 1 rail + wheel + reducer lubrication check.
