General information
For an efficient operation of these automatisms, the gate must have the following features:
- good stoutness and stiffness
- every wing must have one only hinge (if necessary, eliminate the others).
- all hinges must have positive clearances and permit smooth and regular manual operations.
- when wings are closed their height have to fit together.
1. General features
A completely built-in system that does not alter the appearance of gates.
Simple and reliable, it can be installed on any hinged gate of up to a max. 3.5 m per wing (3m max for TERRA FC-V
model).
Movement is quiet and smooth thanks to a lever system that adjusts the speed depending on the different operation
phases.
The full oil bath motor units prevents water seepage and formation of condensate which might permanently damage
motor operation.
Electric locking is not required because the irreversible system ensures locking of the wings.
Installation is easy; once the box is embedded, the motor unit is fastened with stainless-steel nuts and bolts.
A special key is supplied to release it for manual manoeuvre.
The foundation boxes are in hot-galvanized sheet metal to guarantee longer life.
Device 180 TER-FC offers 180° opening (for wing lengths not exceeding 2 m).
The same 180 TER-FC can be used for the automation of special passages.
2. Mechanical stops (fig. 1)
The gate to automate must have an opening and closing mechanical stop as the TERRA FC-L/TERRA FC-V is not
equipped with electro-magnetic limit stops. The TFC limit switch kit, easy to install and adjust, is in any case available.
3. Foundation box laying
Dig as per instructions given in fig. 2 and make sure that on one of the four angles, where suitable holes have been made,
a water drainage and a cable terminal have been prearranged. (fig. 3)
Cement the box and check it is horizontal with the level.
4. Motoreducer fixing
4.1 Fix the motoreducer with the 4 stainless steel M10 hexagon nut (part of the supply) that are fitted onto the screws
projecting from the embedded box.
P.N. In the box there are 8 screws; use the ones that are suitable to the requirements as per instructions given in
Fig.4.
4.2 Weld the drive unit to the wing as per Fig. 5.
4.3 Place the wing into its seat after fitting the ball between the foundation box pivot and the drive unit (Fig. 6).
4.4 Connect the drive unit with the motor flask through the connection lever (Fig. 7)
4.5 With the door leaf resting onto the closing stopper, adjust the screw V, Fig. 7, at a distance of 1/2mm from the linking
lever (in the case of standard mounting only).
4.6 The mechanical stopper for 90° opening is available as optional. It must be placed in the special housing on the
drive bracket, as indicated in Fig. 7.
4.7 Before tightening the M10 nuts, check that the gear motor rests solidly on the bottom of the casing. Conversely,
shim where required, keeping in mind that the gear motor should rest flat (check by using a level).
5. 110° opening (fig. 7)
When positioning the boxes for 110° opening, Art. 110 TER, calculate dimension X (between pivot and load bearing
corner) so that it permits the rotation also in consideration of the gate thickness Y.
6. 180° opening
Device 180 TER-FC offers 180° opening and use the 110 TER box. This option is recommended for wing length up to 2
m; it can also be used for longer lengths but in this case operation would not be smooth and regular.
