4.0
CHECKING AND ADJUSTING THE THRUST
FORCE
With the gate leaf moving, measure the thrust force at the end of the
gate leaf, using a dynamometer
The thrust force must never exceed
If necessary, adjust the working pressure of the operator.
Using a broad, flat-headed screwdriver, turn the control valves
clockwise to increase the pressure and counter-clockwise to reduce
it.
Adjust both opening (silver - E7 pos. 2) and closing pressure (gold
- E7 pos. 1).
Caution
• The opening thrust of the gate leaf should be set slightly higher
than the closing thrust.
• After making the settings, make another check with the
dynamometer to see if the thrust force corresponds to the
setting; if it doesn't, then the setting needs to adjusted
again.
• If the gate leaf requires an excessively high pressure to move
it, then make another thorough check of the mechanical parts,
the plumb and the free movement of the gate leaf itself.
