5. MECHANICAL INSTALLATION

Herewith you start mechanical installation of the gate operator.

5.1 Dimensions of Gate and Operator

CHLA250EVC
830 (max.1150)
CHLA250EVC
1.5 m 200 kg
2.0 m 150 kg
2.5 m 100 kg
5.2 Post Bracket Position and A&B Dimensions
Determine the A and B dimension based on the opening angle provided in Table 1 to confirm the position where the post bracket will be mounted.
1. To ensure that the motor does not touch the pillar, please define your C dimension using B-60 mm formula.
2. For optimal mechanical advantage A and B dimension shall be equal or not differ by more than 40 mm.
NOTE: Smaller A and B dimensions determine higher peripheral speed of the leaf. Higher differences between A and B dimensions cause greater speed and force variati-
ons during the gate opening and closing movement. It is always good practice to use all available travel of the operator.
All crushing points must be secured by an entrapment protection according to EU: EN 12453, EN 60335-2-103; GB (UK, NI): BS EN 12453, BS EN 60335-2-103.
