ADJUSTMENTS AND CHECKS
After installing the unit you have to carry out the electrical connections and check as follows:
1. Check the rotation direction.
Open the door manually half-way and reconnect the release device. Give an impulse with the remote control. If the door
closes, invert the electric motor connections.
2. Timing adjustment.
The unit does not have limit switches. The motor timing is adjusted by a time switch located on the electronic control unit.
The correct setting is approximately 3 seconds longer than it takes for the door to open or close.
3. Pressure settings.
The door working torque is produced by the operator; it is adjusted by the two pressure adjusting valves that act directly on
the maximum reflected pressure. The adjustment is carried out by
turning the right hand valve to increase or decrease the
closing pressure and the left hand valve to adjust the opening pressure.
Turning clockwise increases the minimum working pressure.
During the closing movement the crushing force of the door must not exceed 15 daN as recommended by the UNI 8612
Standard. Pressure calibration must always be slightly different, with the opening pressure set higher than the closing
pressure.
- Pressure adjustments must be made while the motor-pump block is working.
- The pressure adjusting valves only adjust the working pressures, not the speed.
- The pressure adjusting valves do not influence the hydraulic locking of the unit.
SERVICING
The Scuti does not require any particular service attention. It is advised to:
1) Grease all the moving parts.
2) Regularly check the oil level and refill any time it is close to minimum.
3) Change the oil once a year on medium to heavily used doors and every 2 - 3 years on moderately used doors.
The recommended oil is SEA OX SUPER type and we recommend that the installer supplies the correct oil for topping up to
avoid the wrong oil being used.
