AUTOMATIC
In this operating mode, the outputs of the control unit follow the
status of the photocell:
•
with the protected area free (outputs of the photocells active), the
relay outputs of the control unit are active.
•
with the protected area occupied (outputs of the photocells de-
activated), the relay outputs of the control unit are de-activated.
Figure 9
Use in manual mode (start/restart interlock activated) is mandatory in the
case in which the safety device controls an access protecting a danger zone
and once a person has passed through the opening, he/she may remain in
the danger zone without being detected (use as trip device according to
IEC 61496). Failure to comply with this rule may result in very serious risks
for the persons exposed.
Check correct functioning of the entire safety system (control unit+photocell)
following each re-installation. In particular, if the original operating mode was
Manual, check that the unit has been reconfigured in this mode.
