GD0K gearmotor for sectional and overhead door
Type
Electromechanical gearmotor for automated sectional and overhead doors incorporating a control unit com-
plete with radio receiver for “TX4” transmitters.
Adopted technology
24Vdc motor, helical teeth reduction gear; drive guide with timing belt and mechanical release A transformer
inside the motor but separated from the control unit reduces mains voltage to the nominal voltage of 24Vdc
used by the automation system.
Peak thrust
[corresponds to the force necessary to
move a leaf]
9.9Nm
[550N]
Nominal torque
[corresponds to the force necessary to
keep a leaf moving]
4.95Nm
[275N]
Speed under no load
[corresponds to if “Fast” speed is
programmed]
103rpm
[0.14m/s]
The control unit allows 2 speeds to be programmed equal to approx. 100% - 60%.
Nominal torque speed
[corresponds to if “Fast” speed is
programmed]
52rpm
[0.07m/s]
Maximum frequency of cycles
30 complete cycles per day (the control unit allows up to a maximum of 10 cycles per hour)
Maximum continuous cycle time
3 minutes (the control unit limits the continual function to 3 minutes at nominal torque)
Working Limits
Its structural characteristics make it suitable for use on sectional and overhead door with counterweights
within the following parameters:
- Sectional doors: 240cm max. high - 300cm (7.2 m
2
) max. wide - maximum torque 55kg
- Overhead doors: 240cm max. high - 270cm (6.48m
2
) max. wide - maximum torque 55kg
Power supply GD0
Power supply GD0/V1
230Vac (±10%) 50/60Hz
120Vac (±10%) 50/60Hz
Max. absorbed power
200W
Insulation class
1 (a safety grounding system is required)
Emergency power supply
---
Flashing light output
For visual signalling devices with 12V lamp, maximum 21W
Courtesy light
12V lamp maximum 21 WBA15 socket (automotive type lamp), stays on 60s after the manoeuvre
“PHOTO” input
For safety devices such as the PH0 photocell
“OPEN” input
For normally open contacts (the closing of the contact causes the “OPEN” command)
STOP input
For normally open contacts and/or for 8.2K
Ω
constant resistance, or normally closed contacts with recogni-
tion of the “normal” status (any variation from the memorized status causes the “STOP” command)
Radio aerial input
52
Ω
for RG58 or similar type of cable
Maximum cable length
Mains power supply: 30m; inputs/outputs: 20m with aerial cable preferably shorter than 5m (observe the
directions regarding the minimum gauge and type of cable)
Remote control possibility
with TX4 transmitters, the control unit can receive one or more of the following commands: “OPEN”, “Open
partially”, “Open only” and “Close only”
TX4 transmitters memorized
Up to 150 if memorized in mode 1
Range of TX4 transmitters
From 10 to 50 m without aerial, from 50 to 100 m with aerial incorporated in the FL1 flashing light.
The range can vary if there are obstacles or electromagnetic disturbances, and is affected by the position of
the receiving aerial incorporated in the flashing light.
Programmable functions
“Cycle” or “Complete cycle” operation (automatic closing)
“Slow” or “fast” motor speed.
The pause time in the “complete cycle” mode can be set at 15, 30, 60 seconds.
The type of pedestrian opening can be selected from 4 modes. The sensitivity of the obstacle detection sys-
tem can be selected from 3 levels. The operation of the “Open” command can be selected from 3 modes
Self-programmed functions
Automatic detection of the type of “STOP” device (NO or NC contact or 8.2K
Ω
resistance) Automatic detec-
tion of door length and calculation of deceleration points
Operating ambient temperature
-20 ÷ 50°C
Not suitable for use in acid, saline or
potentially explosive atmosphere
NO
Mounting
Horizontal
Protection class
IP40
Dimensions / weight
