8- DIAGNOSTICS LED:
after checking the cabling and the settings of the dipswitches and the jumpers, turn on the power and check
the LEDs on the transmitter and receiver with reference to the table and figure 8:

Description
DL2
Flashes to indicate normal operation
-
DL1 Flashes to indicate the quality of alignment: between 1
and 5 flahses, where 5 flashes indicate perfect align-
ment and 1 flash indicates insufficient alignment (try to
obtain the maximum number of flashes). A long flash
indicates that the SNOW FILTER function is enabled.
-
DL2 Indicates the status of the output contact, activated
with the contact closed. When dipswitch 4 is OFF,
the LED is activated with the photocell not engaged.
When dipswitch 4 is ON, the LED is activated with the
photocell engaged.
9- OPERATION WITH DIGITAL SYNCHRONISM
make the connections as shown in figure 6 (connect together all
the number 3 terminals of the transmitters), turn ON the number 4 dipswitches of all the transmitters (to enable the synchronism),
and set the dipswitches of the different synchronism address for each pair of photocells, using dipswitches 1-2 and 3; a minimum
of one pair must be set at PHOTOCELL 1 MASTER for synchronising the system. If the photocells are to be powered at alternating
current, all the number 1 (+) terminals of terminal block M1 must be connected to the same pole and all the number 2 (-) termi-
nals of the same terminal block must be connected to the other pole.
10- CONTROL AND ALIGNMENT:
LED DL1 serves to check alignment of each pair of photocells; to increase capacity
and set optimal alignment (5 flashes of LED DL1), loosen screws C as shown in figure 4, turn the printed circuit board slowly and
gently until LED DL1 flashes the full number of times, and then tighten the screws. Repeat this procedure for each pair.
11- TROUBLESHOOTING:
Problem
Cause
Solution
The photo-
cell does not
work
Incorrect power supply
Check the poles and setting of the JAP jumper
Incorrect setting of the synchronism
No pair of photocells is configured as the Master (dip 1-2 and 3 OFF)
Turn ON the number 4 dipswitches of all the transmitters
The dipswitches of each pair must be associated with the same syn-
chronism address
The photo-
cell does not
always work
Photocell not aligned
Align the photocell, checking the number of flashes of LED DL1
Other photocells on the system
Use only photocells of the same type
