MANUAL MODE
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 ).
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.
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.
