Table 10
SELECTION OF MANUAL/AUTOMATIC FUNCTIONING
Manual or automatic operating mode can be set through connection of pins 13 and 14 of the
connector of the receiver.
In AUTOMATIC functioning, the two static outputs OSSD1 and OSSD2 follow the
status of the guarded opening. With the area guarded clear, the outputs will supply
+24VDC, while with the area occupied they will supply 0VDC. Refer to Table 10 and
Table 11 for correct configuration of operating mode.
In MANUAL functioning, the two static outputs OSSD1 and OSSD2 are active only
with the danger area clear and after the light curtain has received a correct RESTART
signal. This command must be sent on pin 14 of the receiver and is active with a
0VDC ---> +24VDC transition.
The minimum duration of the RESTART command must be 100ms.
Use of manual mode (start/restart interlock activated) is compulsory if the safety device
controls an opening to protect a danger area and a person, after passing through the
opening, may remain in the danger area without being detected (use as 'trip device'
according to IEC 61496). Failure to comply with this rule may result in very serious
hazards for the persons exposed.
The Restart control must be installed outside the danger area in a position where the
danger area and the entire work area concerned are clearly visible. It must not be possible
to reach the control from inside the danger area.
