NOTES ON CONNECTIONS
•
The transformer needed to power the system must comply with
standard EN 60742 (dual isolation), or with equivalent isolation,
e.g. VDE 0551.
•
The control unit must be protected with an external fuse, whose
rated breaking current must be 1A.
•
The TEST/RESTART button must be located so that the
operator can see the protected area when restarting
,
testing or
overriding.
•
The external illuminated indicator for
muting override
enabled
must be located so that it can be seen from all sides of
operation.
•
Read the section on the
muting
function and its use before
locating the sensors for the activation of this function.
•
Check that the load does not absorb current in excess of
500mA; in this case a protection device will intervene to limit the
maximum current. If loads with currents in excess of 500mA
and up to 6A alternating current are to be controlled, please
connect an external safety relay module.
•
Muting input A and Muting input B can be provided by
mechanical switch, photoelectric sensors, proximities switch,
with closed contact in the presence of the object to be detected.
•
The test connection must always be executed with a N.C.
button or connected to an automatic device, such as a PLC.

5 ALIGNMENT
PROCEDURE
After completing correct mechanical assembly and connections, as
described in the previous sections, the SLC should be aligned as follows:
•
Disconnect the SLC’s power supply.
•
Open the
test/restart
contact.
•
Restore the SLC’s power supply.
•
Adjust the direction of the SLC by moving the transceiver or the
mirror. The 2 yellow LEDs located on the transceiver will both be
lit when the SLC is aligned correctly. In addiction also the green
guard LED will switch on and the red break LED will switch off
•
After aligning the SLC, secure the bolts firmly.
•
Disconnect the power supply.
•
Restore the SLC’s power supply (with the
test
contact closed); it
will enter operating mode.
•
Complete all the tests described in section 9 (final checks) and
those required for routine maintenance (section 10).
