Overload of the OSSD outputs
Carefully check the connection of PIN 2 and 3 (OSSD)
on the connector. If necessary, adjust load reducing
the current required to max 500 mA (2.2
µ

Interfering Emitter detected
(THE CODE REMAINS VISIBLE FOR
AL LEAST 30s)
Carefully locate the interfering Emitter and take action
in one of the following ways:
•
Switch the position of the Emitter and Receiver.
•
Move the interfering Emitter to avoid this illuminating
the Receiver.
•
Shield the beams coming from the interfering Emitter
using opaque protections.
In any case, when faced with a system fault, switch the system off and then on again, to exclude
any occasional electromagnetic disturbances.
Should the problem persist, contact SCHMERSAL. In case of continued malfunctioning:
•
verify the integrity of electrical connections and check that these have been made
correctly;
•
check that the supply voltage levels comply with those specified in the technical data
sheet;
•
the light curtain power supply should be kept separate from that of the other electric
power equipment (electric motors, inverters, frequency converters) or other sources
of disturbance.
•
make sure that the Emitter and the Receiver are correctly aligned and that the front
surfaces are perfectly clean.
If it is not possible to clearly identify the malfunction and to remedy it, stop the machine
and contact SCHMERSAL.
If correct system operation cannot be restored after carrying out the above procedures, send the
equipment to SCHMERSAL, complete with all parts, stating clearly:
•
the product code number (the
P/N
field is shown on the product label)
•
serial
number
(the
S/N
field is shown on the product label)
•
date of purchase;
•
period of operation;
•
type of application;
•
fault.
In order to ensure the correct operation of the photoelectric barrier, careful and full compliance
with all the rules, instructions and warnings stated in this manual is essential.
SCHMERSAL declines all responsibility for events arising from non-compliance with all or part of
the aforesaid instructions.
Subject to technical modifications.
