Fitting onto the limit switch brackets
The bases are complete with hooking tongue allowing the fitting of the magnets to the limit switch bracket supplied with the operator, as shown in Fig.14-B.
This type of fitting allows to rapidly adjust the position of magnets. After calculating the correct distance, fix the support in the correct position by means
of a screw, so as to avert the moving of the bracket.
Fitting onto the rack
As an alternative, the supports can be fitted directly to the rack, by using the slots shown in Fig. 14-C. This fitting mode does not allow for subsequent
regulations. It is therefore advised to make some trials with temporarily fitted supports before carrying out the final fitting.
IMPORTANT: The correct distance of the magnet with respect to the sensor depends on the installation characteristics. This space cannot be preset
and must be adjusted on a trial basis.
The distances regarding the triggering of the sensor (value X) with respect to distance K of 3 and 35 mm, which are shown in Fig. 14 are only indicative.
In any case, distance K must not exceed 35 mm as a higher distance will not allow the triggering of the magnetic sensor.
11) BUFFER BATTERIES (fig.15)
An optional kit of buffer batteries is available. This permits the operation of the system also in case of power failure.
The batteries can be installed inside the gear motor as shown in Fig.15.
The support of the control unit has a hole “Fig.15 ref. "A" which facilitates passage of the battery cables.
For further information, please see instructions supplied with the product.
12) WIRE DIAGRAM (fig.16)
For the wire connections of the system and to adjust the operating modes, please refer to the Instruction Manual of the control unit.
In particular, the anti-crash device (encoder) should be adjusted according to regulations in force.
Please remember that the device should be earthed by means of the appropriate terminal.
Fig.16 shows wiring for a standard installation. Before proceeding to wiring, check that the type of cables used is consistent with those required for ac-
cessories.
Dimension H stands for the installation height of photocells. A clearance between 40 and 60 cm is advisable.
