CONFIGURATION AND OPERATION MODES
The SLC / SLG 210 RF operation mode is selected realizing appropriate connections on the
M12 8 poles of the Receiver (Table 6 and Table 7).
AUTOMATIC MODE
The SLC / SLG 210 RF light curtain / light grid does not dispose of a start/restart
interlock circuit in automatic mode. In most applications this safety function is
necessary. Please consider the risk-analysis of your application about this matter.
In AUTOMATIC mode, the two static outputs OSSD1 and OSSD2 follow the status of the
guarded opening.
with the area guarded clear, the outputs will 24VDC;
with the area occupied they will supply 0VDC.

MANUAL MODE
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.
In this operating mode the safety outputs OSSD1 and OSSD2 are activated (+24VDC) only if
the protected area is free and after the reception of the RESTART signal, using a push
button or thank to an appropriate control on the SEL_A or SEL_B input (ref. Table 7).
After an interception of the protected area, the safety outputs will be de-activated.
To re-activate them it will be necessary to repeat the sequence described above.
The RESTART command is active with a voltage of +24VDC.
The minimum duration of the RESTART command is 400ms.
