Installation
CAUTION: Before proceeding with the installation of
the photocells, check the compatibility and technical
specifications of the control devices to which they will be
connected.
If the installation requires a distance between TX and RX
that is greater than 10 meters, and up to 15 metres, then
the bridge located in the back of the circuit will have to be
cut (see
figure 11
). Be sure to execute this as precisely as
possible without damaging the circuit.
CAUTION: If the installation requires a distance between TX
and RX of less than 2.5 meters, then the TX and RX lenses
must be removed: otherwise their proper functioning
cannot be guaranteed.
The minimum distance allowed is 80 centimetres.
Remove the lenses carefully, so as not to damage the
photodiodes or other components.
5.1
Mounting
Choose the location of the photocells.
Open the photocells, pull-out the electronic circuit cards
(see
figure 6, 7, 8
).
Attach the bottom of the shell.
IIn the case of installation of
G90/F4ES/TRIX/TX
and
G90/F4ES/TRIX/RX
: fix the upper part (detail
F, Figure
8
) to the column TRIX with the screws provided. Put the
4
Terminals and signalling
Terminals for photocell TX (see
figure 1):
1
positive supply 24Vdc, phase A supply 24Vac
2
negative supply 24Vdc, phase B supply 24Vac
3 SYNC,
synchronism
LED for photocell TX signalling (see
figure 1):
L1
turned on when supply voltage is present, if it is off, this
means that the power supply is missing or incorrectly
connected
Terminals for photocell RX (see
figure 1):
1
positive supply 24Vdc, phase A supply 24Vac
2
negative supply 24Vdc, phase B supply 24Vac
3,4 OUT,
OUTPUT normally closed contact with
functioning photocells and without the presence of
obstacles between TX and RX
5 SYNC,
synchronism
LED for photocell RX signalling (see
figure 1):
L2
normally off; in “alignment” mode it indicates
the intensity of the received signal by varying the
frequency of flashing
L3
indicates the status of the output contact
OUT,
it is
normally turned on (contact closed), it turns off when
there is an obstacle between the photocells (contact
open)
