Please, note:
•
To configure the control unit in such a way that it works only with
three photocells, it is necessary to connect the unused transmitter
output to the corresponding receiver input, in this case to terminal
TEST-TX3 with PNP_OUT-RX3.
•
All models can be connected in all the possible combinations for a
maximum of four pairs of sensors with at least one pair connected.
•
The power supply which is necessary to power the system must
conform to standard EN 60742 (double insulation) or with equal
insulation, for instance VDE 0551.
•
It is necessary to protect the control unit with an outer fuse having a
nominal interruption current equal to 1 A.
•
The TEST and RESET pushbuttons must be positioned in such a way
that the operator can see the protected area when he restarts, or
carries out a
test
or
override
operation.
•
The Muting lamp (F39-A11) be positioned in a place where it can be
seen from any operative point.
•
Read the paragraph relating to the
muting
function and its use for the
positioning of the activation sensors of this function.
•
Both safety contacts OUT1 and OUT2 must be connected. If the
machine has a single locking circuit, the two normally opened
contacts must be connected in series.
•
The connection cables of the photocells, of
muting
request,
start
and
test
must be masked with minimum section 22AWG. The screen
braids must be all earthed towards the control unit side.
