IOR5MS ENGLISH
One simple alignment system consists of placing a flashing white light in line with the transmitter to set the
receiver, and vice and versa. The lamp should be placed near the transmitter, aiming it to the relative receiver.
Then set the mirror of the receiver by moving the flashing point of light generated by the lamp to the center of
the white disk on the photocell.
The same operation is then performed again, this time placing the lamp on the receiver side to set the
transmitter. Following these operations, the IOR5MS is 70-80% aligned.
Make sure the relay on the receiver switches on properly by interrupting the infrared ray.
For complete alignment, use a analogical tester with a base scale of 10 VDC.
Measuring the voltage at the Test-Point, make the necessary adjustments to the transmitter and receiver mirrors
to obtain the maximum voltage (Fig. 4).
For this purpose we have provided the enclosed table, which shows indicative
readings on the tester in relation to the transmitter-receiver distance.
Set the photocell intervention time using the dial provided (fig. 4).
By turning the dial counter-clockwise the time is reduced to the minimum (thus
maximum speed), which is 30 ms; by tuning it instead clockwise, the maximum
time (minimum speed is achieved), which is 300 ms.
Check several times that the relay (exchange) responds properly by
interrupting the infrared ray.
Pre-alignment with a lamp
ALIGNMENT WITH MULTIPLE BEAMS
To operate the IOR5MS in multiple-beam mode, the user must enable the synchronism signal on the receiver
circuit by checking that the SYNC jumper is disabled and then switching the slide selector on the transmitter
circuit to MASTER position for the MASTER beam transmitter and to SLAVE position for the transmitters of all
the other beams. If the barriers have multiple rays, proceed as described above for each ray, but make sure to
use the special screen provided (cardboard) to block the transmitters of the photocells not being set
(fig.7).
TRIGGER CONTROL (T.C.)
Use of the T.C. makes it possible to turn off operation of the relay, thus avoiding needless wear caused by
switching when the system is not running and allows certain areas to be excluded and the system to be used
only in part.
It is also possible to turn off several photocells simultaneously by connecting the various T.C. 's to each other.
If using the disengage boards, the T.C. command from the control center (+ 12 VDC arriving from a contact) is
sent to the various devices or groups of devices by means of a diode.
A group of devices is considered as all of the receivers that report to a single disengage.
DISQUALIFICATION (DISIORE)
The IOR disengage is an optional circuit that may be
connected to the photocell receiver. The function of this board
is to disengage the photocell(s) if, for any cause (i.e., fog) there
is a slow and gradual reduction of the signal such as to
compromise the correct functioning of the photocell(s).
The intervention point of the disengage is adjustable, and a
special filter (perforated cardboard) is provided to assist you in
setting it.
N.B.: For outdoor installations it is most important to remember that fog, rain, etc. cause a signal reduction and
therefore nominal range may be reduced down to 75% (i.e. 35-40 m.).
