Important information
DANGER
During Smart Box Detection Override, the protective field is not monitored.
Persons or body parts to be protected may not be detected.
b
Prevent access to the hazardous area during execution of Smart Box Detection
Override.
NOTE
If automatic measurement of the protective field width is configured and the protective
field is interrupted when the ESPE is switched on for the first time, the system changes
to the override condition if the override conditions are fulfilled. If override is performed,
the OSSDs change to the OFF state again after the protective field frees up again, if
necessary, until the protective field width is automatically measured.
Configure a dynamic protective field width to bypass this behavior.
Prerequisites
•
The Smart Box Detection Override control switch is mounted outside of the hazard‐
ous area so that it cannot be actuated by a person that is inside the hazardous
area.
•
The operator can oversee the entire hazardous area when actuating the control
switch.
Performing Smart Box Detection Override
When a Smart Box Detection condition is violated, the OSSDs switch to the OFF state.
The Smart Box Detection Override required state is triggered by the system only when
the following conditions apply:
•
The protective field is interrupted and the beam status of the protective field
remains the same for 5 s.
•
The top light beam is not interrupted.
•
The integrated laser alignment aid of the sender is switched off.
If the conditions apply, the system changes to the Smart Box Detection Override
required state. The cause of the error is indicated by the LEDs on the receiver. If an
optional signal lamp is connected, this signal lamp also flashes.
To remove an object from the protective field, you can trigger the integrated Smart
Box Detection Override function via the control switch. This causes the output signal
switching devices (OSSDs) to switch to the ON state. Alternatively, you can eliminate the
cause in another way, e.g. clearing the belt.
As soon as the protective field is free, Smart Box Detection Override is terminated.
Monitoring override states
The number of Smart Box Detection Override states is limited to 5. The system auto‐
matically resets the counter each time the system is switched on and after every
error-free cycle without an override.
If the permitted number of Smart Box Detection Override states has been exceeded,
the system then switches to the locking state and displays an error message.
Complementary information
If reset and Smart Box Detection Override are configured on the same input, both
functions are started using a common control switch.
