r-tec COUPER 24

Overview

In the r-tec swing-gate range, COUPER 24 is the classic standard that most projects start from. Its two-piece articulated-arm mechanism comfortably drives up to 2 m of leaf length at 250 kg maximum door weight. That balance is exactly why it is the most widely chosen swing motor for residential, villa and small-complex garden gates: simple design, battery backup compatibility and IP44 outdoor durability in one package.

COUPER 24 vs JET 24 vs PRINCE 24

	COUPER 24	JET 24	PRINCE 24
Arm mechanism	Articulated (classic)	Fast articulated (powerful)	Telescopic
Motor power	85 W	120 W	70 W
Max. leaf	2 m	3 m	4 m
Max. weight	250 kg	600 kg	500 kg
Speed	1.3 / 1.6 cm/s	1.3 / 2.0 cm/s	1.6 / 2.0 cm/s
Market	Residential standard	Heavy door + frequent use	Wide leaf

→ For standard use below 2 m leaf + 250 kg, COUPER 24 is the first choice; for heavy doors + frequent use, JET 24; for wide leaves up to 4 m, PRINCE 24.

Site geometry — A-E dimensions

In motor arm installation, the A-E distances between the door hinge axis and the motor shaft axis are determined according to the installation diagram in the PDF. These dimensions directly affect the opening angle (90° / 100° / 110°):

• 90° opening — Standard A dimension (compact installation)
• 100° opening — Increased A dimension (medium strut)
• 110° opening — Maximum A dimension (deep strut for wide manoeuvre)

In the site survey, the distance to the door wall and strut thickness are measured to select the correct A value.

Battery backup

COUPER 24 provides battery backup with the G24 control board + battery charger board module combination:

• 24 V 7 Ah battery → ~30-50 open-close cycles tolerance during power outage.
• 24 V 12 Ah battery → ~50-80 open-close cycles.
• The charging circuit drives a light charging current with the battery connected continuously; overcharge protection is included.
• Battery life is typically 3-5 years; voltage test is performed during periodic maintenance.

Target projects

• Residential garden gate (single family or small estate)
• Villa main entrance gate (single or double leaf)
• Eco-house + solar-powered systems (24 V naturally)
• Historical residence + aesthetically-prioritised entrance
• Estate internal additional entrance gates

Field discipline

• Hinge quality — Sprung or well-bearing hinges reduce motor load; on doors with old/stiff hinges, the motor thermal protection trips early.
• A dimension precision — Incorrect A dimension disrupts the opening angle; calibration is mandatory according to the PDF table.
• Power trimpot — The T1 motor power trimpot must be adjusted according to the door weight.
• Double-leaf synchronisation — Two COUPER 24 motors are driven in a double-leaf system with the G24-MTS module; sync limit setting is critical.
• Follow the order in the document for synchronisation limit setting on double-arm installation.

Model notes

Follow the order in the document for synchronisation limit setting on double-arm installation. For wide-leaf (2 m+) or heavy-door (250 kg+) applications, PRINCE 24 should be evaluated; borderline use causes early thermal protection trips.
