Overview
The 220-K is the contactor-based member of the r-tec control unit family aimed at 380 V three-phase motorised door systems. Operating through opening and closing contactors, the unit delivers controlled, safe three-phase door control in workshops, garage services and production sites — across industrial sectional and roll-up door applications.
220-K vs I-380 vs FU
| 220-K | I-380 | FU | |
|---|---|---|---|
| Mains | 380 V three-phase | 380 V three-phase | 220 V single-phase |
| Drive type | Contactor-based | Direct-drive | Inverter (VFD) |
| Target product | Industrial sectional | Standard industrial | HPVC + sliding |
| Soft start | None | None | Available |
| Profile | Compact | Compact | Larger |
| Facility need | Three-phase required | Three-phase required | Widespread |
→ For three-phase contactor-based industrial control, 220-K; where direct-drive is preferred, I-380; in HPVC or applications where soft start is mandatory, FU.
Button cabinet + emergency stop
The distinguishing feature of 220-K is the integrated button cabinet for operator use. On the top surface of the body:
- Open button (green) — Moves the door in the opening direction.
- Close button (green) — Moves the door in the closing direction.
- Stop button (red mushroom emergency stop) — Instant stop; the position accessible from every point of the site is critical.
The operator usually uses these buttons in industrial sites; remote control is optional (as a backup or to open the door from inside the vehicle).
Target projects
- Workshop + repair centre entrance gate
- Service garage (automotive + industrial equipment)
- Production facility (with 380 V three-phase mains)
- Agricultural operation warehouse entrance
- Cold storage
Field discipline
- Three-phase fuse required — The 380 V three-phase line from the electrical panel is connected first to a 10 A three-phase fuse, then the fuse output to the control unit.
- Phase order check — If the motor moves in the closing direction when the Open button is pressed, cut the power and swap the L2 and L3 phases.
- Earthing — Earthing must be connected correctly in a three-phase installation; mains cables permanently carrying 380 V must be kept away from limit switch, encoder and control cables.
- Photocell + safety strip — Photocell is mandatory for operator safety in industrial application.
Model notes
The input-output differences between 220-K and I-380 are numbered on the connection schematic. Both run on 380 V three-phase; the 220-K is distinguished by its contactor-based drive and the I-380 by its direct-drive design.
Frequently Asked Questions
Below we've compiled the most common questions and answers regarding this product.
r-tec control board: the door/boom moves a little and stops when the button is pressed
Likely cause: the motor power (current) trimpot is set too low, so the motor cannot fully drive the door. First step: increase the motor power trimpot on the board (T1 on the GATE 24 board) in small steps until the door moves fully; the increase direction is given in the board/model guide (on the GATE 24 board, for example, the trimpot decreases clockwise and increases counter-clockwise). If travel still fails with the current trimpot at maximum, there may be mechanical binding or a motor/leaf mismatch. Trimpot adjustment must only be carried out by trained personnel, within the range in the model guide.
