3. Instructions for use
3.1 Intended use
GXP motor gearboxes are intended for driving vertical screens or side ventilation, for instance in stables, greenhouses,
halls and façades. The GXP motor gearboxes are directly connected to the roll-up tubes and are led into the right directi-
on by means of a guidance bracket attached to the motor that rolls along a tube which is fixed to the greenhouse. If the
motor gearbox is applied in a lifting application, this is permitted only if a fall-stop protection is being used.
3.2 Special versions
The following special versions are (among others) available in consultation with the manufacturer (not for all systems):
24 VDC;
• Versions suited for different voltages and/or frequency;
• Versions for use in areas with high relative humidity (RV >60%);
• Versions for use in roof slope roller screen installations;
• Versions with specially certified electric motors.
3.3 Conditions of use
When using the motor gearbox, the following conditions should be met:
• Ambient temperature range for usage: 0°C to +60°C [32°F to 140°F].
• The lifting of free-hanging loads (no persons), such as growing tube-, chrysanthemums (hoist)heating or assimilation
lighting is permitted only with fall-stop protection.
• The motor gearboxes are suitable for S3-30% operation.
• The maximum running time is 10 minutes.
• The maximum allowed number of starts per minute for the motor gearbox is 3.
• Low loads and fewer switching cycles, whereby the motor gearbox can cool off in between, will significantly increase
the lifespan of the motor gearbox.
3.4 Restrictions on the use
It is not permitted to make constructional changes to the motor gearbox. Any such modifications render the manufac-
turer’s warranty null and void and relieve the manufacturer of liability for any consequences. Additionally, the following
restrictions apply to the use of the motor gearbox:
• Do not use the motor gearbox/power train with a torque exceeding the indicated maximum torque.
• Do not use the motor gearbox for operating parts that are in the direct vicinity (within easy reach) of persons. Obser-
ve safety distances in conformity with NEN EN ISO 13857.
• Do not expose the motor gearbox to direct irrigation or precipitation (rain/snow).
• Do not use the motor gearbox for operating smoke and heat extraction installations, according to NEN 6093 or DIN
18232.
• Do not use the motor gearbox for operating automatic doors or gates that are being used by persons.
• Do not use the motor gearbox in an explosion hazardous area, unless express permission was given to do so.
3.4 Unintended use (misuse)
We express our explicit warning against the following unintended use:
• Do not use the motor gearbox for the lifting of hanging loads in populated areas;
• Do not use the motor gearbox for the transportation of people (for instance as a passenger lift and the like).
3.5 Storage
In order to assure the life cycle and the correct functioning of the motor gearboxes, the following regulations must be
adhered to:
• Ensure that the motor gearboxes are stored in a dust-free and moisture-free environment
• The relative air humidity of the storage location must be less than 50%.
• Store the motor gearboxes at a temperature between -15 and +60°C [5°F to 140°F].
• Prevent sudden temperature fluctuations to avoid condensation.
• If you wish to store the motor gearboxes for a longer period of time, you can make use of protective agents to pro-
tect unvarnished surfaces, such as threaded holes and the assembly surfaces for coupling sleeves, against corrosion.
