r-tec GIGA Sedo Control Unit

Overview

GIGA Sedo sits at the top of r-tec’s industrial control portfolio. On the board you will find the German-origin Sommer Antriebs- und Funktechnik GmbH manufacturer label — the tangible result of r-tec’s European OEM partnership established after the 2014 Stuttgart fair. Its feature set reaches well beyond the standard I-380 direct-drive board, gathering an LCD screen + password menu, RS485 multi-door, induction loop, traffic light, 8K2 safety strip, 2 optical sensors and 2 photocells onto a single board.

Why Premium?

GIGA Sedo is not necessary in ordinary industrial door applications — I-380 is sufficient at most sites. Scenarios where the premium line adds value:

• Hangar-type wide-opening doors — 4700 × 10000 mm multi-leaf side-folding or telescopic (induction loop + traffic light used together).
• Logistics terminal + cargo distribution centre — Connects to the central control room with RS485, door status is live-monitored.
• Automotive production lines — Multi-safety layer is mandatory with 8K2 safety strip (European quality standard), two optical sensors + two photocells.
• Food + pharmaceutical warehouses — Compatible with hygiene inspection systems with service door switch + motor thermal protection.
• Sensitive industrial applications — Untrained intervention is prevented with the password-protected menu.

LCD menu + password protection

After commissioning, all parameters are navigated via the LCD screen. With 3 buttons (Back = Up, OK = Stop, Forward = Down), the multi-language menu is traversed.

Menu steps:

1. Language selection (0200) — Turkish / English / German and others.
2. Time setting (0300) — Time + date (used for logging).
3. Motor direction check (0400) — Automatic motor direction detection.
4. Limit setting (0500) — Upper limit (4027 default) + Lower limit (3222 default).
5. Fine tuning of limits (0600) — Opening + closing fine tuning.
6. Automatic closing — Minimum 5 s.

Password: Factory output 0000. Trained personnel change the password from menu 2570; persons other than dealer/technician teams coming to the site cannot intervene in the parameters.

I/O layers — ~80 clamps in total

The most distinct feature that differentiates GIGA Sedo from I-380 is its detailed I/O set. Clamp groups:

Group	Clamp	Function
Limit switch	1 – 6	Opening / closing / pre-limit
Buttons	7 – 14	Open / Stop / Close / Impulse
Safety strip 8K2	17 – 20	2 channels 8.2 kΩ
Optical sensor (OSE)	21 – 27	2 channels spiral cable tested
Photocell	28 – 33	4-wire + 2-wire
Thermal + service switch	34 – 37	Motor thermal + spiral cable stop
Traffic light	54 – 58	Red / green add-on module
Induction loop	59 – 63	Underground vehicle detector
RS485-1	64 – 67	Central system
Extra relays	72 – 79	Position and status notification
Motor inverter	38 – 42	U / V / W
Earth + neutral	43 – 47	PE + N
Three-phase	48 – 50	L1 / L2 / L3

4 fuse lines (F1/F2/F3 = T10A, F4 = T125mA) form the board protection layer.

Induction loop + traffic light — premium entrance

One of GIGA Sedo’s flagship features is fully smart entrance support for industrial terminals/logistics:

• Induction loop (add-on board required): An underground-embedded wire loop detects the vehicle passing over it. It opens the door automatically without the user pressing a button/remote — no manual intervention is required in logistics terminals with heavy truck traffic.
• Traffic light add-on board: Provides stop/go signal to the driver approaching the door. In the industrial terminal, it shows “STOP” to the approaching truck while the door is still closing, and “GO” signal engages when the door is fully open.

When used together, these two features form an autonomous entry control point — operator intervention is minimal.

RS485 multi-door / central control

Thanks to two RS485 lines (RS485-1 + RS485-2):

• Multi-door parallel control at the same facility (e.g. management of 5 hangar doors from a single central panel).
• Live door status monitoring + log recording (how many times the door was opened, at what time, how long it stayed open).
• Central control room integration — data exchange with SCADA / BMS systems.

Sommer Antriebs partnership — marketing story

The Sommer Antriebs- und Funktechnik GmbH label on the GIGA Sedo board shows that r-tec is a partner manufacturer to European quality standards. This partnership is the tangible result of the business relationship established at the 2014 Stuttgart fair; it confirms that r-tec has direct access to the German engineering supply chain.

Target projects

• Hangar-type automotive production facility
• Logistics terminal + cargo distribution centre
• Port and organised industrial zone entry control points
• Premium food + pharmaceutical warehouses
• Airport industrial service entrances (fire, maintenance, materials)
• High-precision production facilities (clean room, pharmaceutical, semiconductor)

Model notes

GIGA Sedo has a board structure that requires the motor shaft to rotate at least 1 turn before commissioning — the board must not be energised without bringing the door to the half-open position manually. Limit switch settings are made via the LCD menu in the 4027 (up) / 3222 (down) default value range; fine tuning is completed later via menu 0600. Password-protected use is recommended to prevent untrained intervention.

Installation and Commissioning

GIGA Sedo is a premium industrial control; commissioning is done by defining parameters through the LCD menu and it offers advanced integration options. General flow:

• Preparation before power-up: By the board’s design the motor shaft must be able to turn at least one revolution, so the board is not energised before the door is moved by hand to the half-open position.
• Supply and motor: The supply, motor and encoder connections are made; when the LCD is active, the status and event history (history menu) are accessible via the menu.
• Parameter definition: Door type, speed, limit and protection parameters are defined from the LCD menu; error messages appear on the display as readable text (for example “PHASE LOSS”, “ENCODER FAIL”).
• Integration: Remote reading over RS485 and access-control accessories such as an induction-loop detector are configured.
• Test: Parameters are verified over a few cycles; the message-meaning table is matched from the guide.

Parameter and integration settings must be made only by trained personnel, per the model guide.
