The gear motors GR 100 have been planned and built in order to open

all those gates as above mentioned. GR Srl is not responsible for any

abnormal and/or different use of the gear motors GR 100. As the

automation can be controlled from distance through a remote control,

you must always check the full efficiency of all the safety devices. We

recommend inspecting periodically (every 6 months) the adjustment of

the electronic friction.

PRELIMINARY CHECKS

1 - Read carefully the instructions enclosed in this manual.

2 - Make sure that the gate has a rather solid structure and that there is

no friction points in its movement.

3 - Make sure that the wing is suitably balanced, even after the

installation of the gear motor.

4 - Check that the electrical installation is in accordance with the

characteristic required by the gear motor.

INSTALLATION

To operate a good installation of the gear motors GR 100, follow these

instructions:

1- Open the box and take out gear motor. Make sure that it has

not been damaged during the transport.

2- Make sure that the wing of the gate is perfectly horizontal.

3- Place the basement plate of the motor in according to parameters

of table1, being sure that the wing completely open doesn’t

interfere with the motor
