A SAFE DOOR
The safety of the door operator is controlled by basic adjustments;
operator force, speeds, and hold open times.
- The operator force is an important adjustment. A high value affects to the
safety feature and also to its sensitivity.
- High speeds increases the energy transferred in the door causing it not stop
correctly.
- With hold open times the distance from impulse device to door is preset.
1. Adjust low opening and closing speeds.
2. Adjust the operators opening torque and closing force to a low setting.
3. Adjust the hold open times.
By following these basic procedures the operator is safe in operation.
Note!!! High speeds and safety is only possible by fitting of Safety sensors.
A safe door environment needs ALWAYS a safety sensor.
It is recommended to use safety sensor when possible,
not only with high speeds.
