General Features - Beninca BULL 20HE Manual Del Usuario

1. General information
For an efficient operation of the sliding automatic mechanism, the gate must have the following features:
- The guide rail and its wheels must be suitable in size and mantained to prevent gate from excessive sliding
friction.
- When running, gate must not rock excessively.
- Opening and closing stroke must be regulated by a mechanical limit stop (to safety standard in force).

2. General features

Automation with single-phase power supply for sliding gates, available in 2 models:
BULL 20HE for gates with max weight of 2000 Kg with 230 Vac mains power supply
BULL 20HEA for gates with max weight of 2000 Kgwith 120 Vac mains power supply
The small and elegant design enbloc BULL consists of an aluminium unit containing the motor and irreversible
reduction unit, realized with high-grade materials.
The BULL has a spring-operated limit-switch.
A personalized key emergency release enables manual gate operation in the event of power failure.
Anti-crash safety is ensured by an electronic device (encoder), which detects the presence of any obstacle.
3. Installation of the foundation plate
Dimensions of the foundation plate are shown in Fig. 1.
It is essential to keep the distance from the rack, in order to position and remove the actuator once the rack
is fitted to the gate leaf.
The types of fittings of the foundation plate are mainly the following:
1 Installation without adjustment in height on the already existing base in concrete (Fig.2).
By using the plate as drilling template, drill 4 holes Ø10mm, and insert the steel threaded screw anchors,
Ø10x120mm, similar to those shown in Fig. 2.
Lock the actuator directly to floor, as indicated in Fig.7.
2 Installation with adjustment in height on the already existing base in concrete (Fig.3).
By using the plate as drilling template, drill 4 holes, and insert the Ø 10mm steel screw anchors for threaded
bars.
Tighten the 4 threaded bars, M10/120mm, and anchor the screw anchors by tightening the nuts "B" to floor
with the corresponding washers.
With reference to Fig. 3, position the foundation plate by means of the adjustment nuts "A". After carrying out
the required regulations, position the motor as shown in Fig.6, and lock it, as indicated in Fig.7.
3 Installation with adjustment in height on concrete base.
With reference to Fig. 4, fit the stretcher bolts on the foundation plate and provide for a hole of adequate size.
Immerse the stretcher bolts in concrete, then remove the nuts "D" and the 11x30, large band washers "R".
Move them under the plate to allow for regulations in height of the actuator (Fig. 5).
Carry out the regulations shown in Fig. 6 and lock the motor as indicated in Fig.7.
CAUTION: apart from the fitting modality used, carefully check that the actuator is steadily positioned
and the materials are suited to the intended use.
4. Rack fixing
Iron rack, 12x30mm.
Position the spacers D by welding or fit them to the gate with screws at 130/150mm height from the centre
line of the slot used for fitting to the base on which the foundation plate is to be fixed.
Keep the pitch of teeth between the two parts of the rack; the joining with another piece of rack would make
it easier to achieve (see Fig.8)
Secure the rack with the screws V making sure, once the actuator has been installed, that between rack and
the drive gear there is always approx. 1mm clearance (see Fig.9); to get this clearance use the slots on the rack.
5. Limit stop flask positioning (see Fig.10)
Open manually the gate and leave approximately of 1÷3cm, depending on gate weight, between gate and
positive mechanical stop A; tighten the limit stop flask S with the grains G to press the limit stop micro. Repeat
the sequence with closing gate.
