Introduction
Thank you for choosing our MS424 ratiomotor. All items in the wide Benincà production range are the result of twenty-
years' experience in the automatism sector and of continuous research for new materials and advanced technologies.
We are, therefore, in the position to offer higly reliable products that due to their power, effectiveness and useful life, fully
satisfy the final user's requirements.
All our products are manufactured to the existing standard and are covered by warranty.
Possible injury to people or accidents caused by defects in construction are covered by a civil liability policy drawn up
with one of the major insurance companies.
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 for private use sliding gates (max. gate weight 400Kg).
The small and elegant design enbloc MS424 consists of an aluminium unit containing the motor and irreversible reduction
unit, realized with high-grade materials. The MS424 has a spring-operated travel-end. A personalized key emergency
release enables manual gate operation in the event of power failure.
3. Laying of the foundation plate
Fit the foundation plate onto the floor according to dimensions given in fig.1, by using 4 steel T screw anchors (in any
case the plate should be perfectly anchored to the floor). Provide for a tube to house the supply cables.
4. Rack fixing
4.1 Nylon rack
Place the rack at a height of 111mm from the centre line of the fitting slot to which the foundation plate is to be fitted.
Drill and thread (M6) the gate in that point. Fix the rack according to points 4.3 and 4.4.
4.2 Iron rack, 12x30mm.
Position the spacers D by welding or fit them to the gate with screws at 148mm height from the centre line of the slot
used for fitting to the base on which the foundation plate is to be fixed. Fix the rack according to points 4.3 and 4.4.
4.3 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.3)
4.4 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.4); to get this clearance use the slots on the rack.
5. Actuator positioning and fixing (see Fig.5)
Remove the case by untightening the screws V. The group should be positioned with the gear centred with respect to
the rack, level it by using the screws G and, if necessary, adjust the clearance between rack and gears (according to
Fig.4). Now tighten the nuts D.
6. Limit stop flask positioning (see Fig.6)
Open manually the gate and leave approximately of 1÷3cm, depending on gate weight, between gate and positive me-
chanical stop A; tighten the limit stop flask S with the grains G to press the limit stop micro. Repeat the sequence with
closing gate.
CAUTION
The civil liability policy, which covers possible injuries to people or accidents caused by defects in construction, requires
the system to be to existing standard and to use original Benincà accessories.
