MOUNTING INSTRUCTIONS
INSTALLATION
For this type of gate there are four mounting types: (see Pag. 4 )
Depending on the required opening angle "G", select dimensions "A", "B" and "C" to suit as per Pag. 4.
PROCEDURE
1.
Choose a mounting position at a height where the gate has a rigid surface to mount the front bracket.
2.
Fit the rear bracket as per dimensions indicated in Pag. 4.
3.
Mount the locknut G, (fig. 4) Pass the cables trough "E" hole from the rear hinge H, (Fig.3), then, crimping the terminals and connecting them
according to the diagram of the figure 2.
4.
Thread the rear hinge H, to the unit, place it on the bracket, ensure than the red and green valves are centered at the bottom as shown in figure
1, and screw the locknut.
5.
Electrically extend the operator fully.
6.
Screw in the rod-end, with is lock nut, until there is 5mm. thread left. With the gate closed, position the front bracket with dimension "C" as per
pag. 4 and mark its position on the gate, ensuring the operator is completely level.
7.
Remove the operator and fix the front bracket in its required position. It is important to remove the operator at this stage to avoid damage to its
chromed rod with the sparks of the welder.
8.
Before re-fitting the operator, grease the bracket pivot pins, assemble and check manually that it works correctly. If so, proceed to adjust the
operator.
9.
Adjust the closed position of the gate by screwing in or out the rod end ( be very careful not to damage the rod of the operator with tools
which could scratch it).
10. We then adjust the opening and closing times of the control card such that the motor runs for approximately 4 seconds more than the required
for the full stroke in each direction.
11. We then proceed to adjust the pressure adjustments with the check valves (marks A and B, fig.1, page 3). These should be screwed-in
approximately one turn more than the pressure required for the operator to start to move, as this guarantees the maximum safety for the user.
The green valve "B" controls the pressure for the rod retracting and the red valve "A" the pressure for the rod extending. For operators with check
valves, the opening pressure should always be higher than the closing pressure.
MAINTENANCE
The oil should be changed every 2 years or every 250,000 cycles.
-
Every year and every time the operator is removed, the pivot pins on the brackets should be greased. This should be done more often for
-
operators in wet conditions.
TYPICAL PROBLEMS AND SOLUTIONS
The motor runs, but the gate does not open or close: the relevant pressure adjustment is set too low.
-
The gate opens in a jerky manner, or the damping doesn't work: pressure adjustments set to high.
-
The gate doesn't close completely: check motor time sufficient and, if so, unscrew rod end to suit.
