General Information - BFT SUB BT Instructions D'installation

1) GENERAL INFORMATION

The SUB BT hydraulic actuator is ideal for in-ground under-hinge appli-
cations. It is a brilliant solution to the problem of making the automated
system aesthetically unobtrusive. The SUB BT actuator comes as a water-
proof self-contained unit incorporating the hydraulic power pack-jack,
which means it can be installed fully under ground without the need
for any hydraulic connections.
The gate is kept closed by a hydraulic locking feature or by a solenoid
lock. The actuator features soft-closing so that the gate opens and
closes without clanging; operating force is adjusted automatically and
extremely accurately by means of the control unit's electronic control.
The actuator features built-in mechanical limit stops that can be adju-
sted over the last 32 degrees of the gate's opening and closing travel to
make the installer's job easier and also avoid having to install external
mechanical stops.

CAUTION!!! If you are using two solenoid locks in the installation,
you will need to run the second lock off a separate power supply.

4) ADJUSTING THE TRAVEL LIMITS AND STOPS FIG. B:
Warning! Do not attempt to move the leaf using the limit stop
adjustment screw.
WARNING! Make sure that the leaf approaches the opening and
closing travel limits at slowed speed.
Turning pin "A" (- direction) --> leaf angle decreases.
Turning pin "B" (+ direction) --> leaf angle increases.
The pin can be turned manually or with a battery-powered screwdriver
set to 1.5 Nm.
13 turns of pin "A" = limit stop moved by 1.5 mm ≈ 3° Leaf (opening-
closing). Total FCM1 movement: 15 mm ≈ 32°.
FIG. B1:
- Release the operator by opening the service valve (Ref. 1).
- Close the leaf (manually) (Ref. 2).
- Turn the closing limit stop pin "A" as far as it will go in the (-) direction
(Ref. 3).
- Sample adjustments (Ref. 4):
- up to 120° (Ref. A)
- up to 93° (Ref. B).
- Open the leaf manually (to the desired position) (Ref. 5).
- Turn the opening limit stop pin "B" as far as it will go in the (-) direction
(Ref. 6).
