5.4 Operator Mounting and Travel Distance Adjustment

1. Align the holes on the operator to the post bracket holes and connect using the screws and nuts (see picture 3.a).
2. Connect the arm to the shaft of the motor unit (see picture 3.b). Do not mount plastic protection cover yet, if you plan to install operator hard stops.
3. Release the operator clutch with the release key (see picture 4 on page 7).
4. Bring gate leaf to the closed position.
NOTE: The system must operate with external gate or operator hard stops in both directions.
5.4.1 Installation with external gate hard stops: (gate hard stops already installed)
a. Position the gate bracket in the desired full closed position as shown in the picture 3.c. Temporarily secure it to the gate leaf and connect with operator arm considering
dimensions A, B and C from Table 1.
b. Manually open and close the gate to the required positions. Ensure the operator arm does not bind and gate is moving smoothly.
c. Make permanent connection of the gate bracket at chosen correct position.
5.4.2 Installation with operator hard stops: (no gate hard stops installed)
a. Position the gate bracket in the desired full closed position as shown in the picture 3.c. Temporarily secure it to the gate leaf (do not make permanent connection to
gate leaf yet to enable adjustments) and connect with operator arm considering dimensions A, B and C from Table 1.
b. Manually open and close the gate to the required positions. Ensure the operator arm does not bind and gate is moving smoothly.
c. Fix the operator hard stop for "close" position as close as possible to the arm (see picture 3.d).
Hold the gate leaf in the desired "closed" position and adjust position of the gate bracket, so that the arm pushes against hard stop in "close" position (see pictures 3.e and 3.f).
d. Make permanent connection of the gate bracket at chosen correct position.
e. Open the gate to the required "open" position and fix the operator hard stop for "open" position as close as possible to the arm (see pictures 3.g and 3.h).
f. Mount the protection cover at the operator bottom (see picture 3.i).
4.3 A combination of operator and gate hard stops is allowed. Please use the respective set up procedures as described above.
5. Repeat the procedure for the unit on the opposite side.
