OverridePossible output

Output for the monitoring signal providing notification that an override operation is possible:

Data type: BOOL

Connection: Connect the OverridePossible output to an output terminal of your application (e.g., for an indicating device to signal that an override operation is possible), either directly or via other functions/function blocks.

Value Description

TRUE Override operation is possible.
The following conditions must be met:

The function block has been activated (input Activate = TRUE)

and a muting error is present

and the light beam of the safety-related equipment (e.g., light barrier) is interrupted (S_AOPD_In = SAFEFALSE)

or at least one of the muting sensors detects an object.

FALSE Override operation is not possible.
The following conditions must be met:

The function block is not active (input Activate = FALSE)

or no muting error is present

or the light beam of the safety-related equipment (e.g., light barrier) is not interrupted (S_AOPD_In = SAFETRUE)

or none of the muting sensors detects an object.

Value	Description
TRUE	Override operation is possible. The following conditions must be met: The function block has been activated (input Activate = TRUE) and a muting error is present and the light beam of the safety-related equipment (e.g., light barrier) is interrupted (S_AOPD_In = SAFEFALSE) or at least one of the muting sensors detects an object.
FALSE	Override operation is not possible. The following conditions must be met: The function block is not active (input Activate = FALSE) or no muting error is present or the light beam of the safety-related equipment (e.g., light barrier) is not interrupted (S_AOPD_In = SAFETRUE) or none of the muting sensors detects an object.

WARNUNG

Non-conformance to safety function requirements

Be sure that your risk analysis includes an evaluation of a manual override operation (S_StartStopOverride = SAFETRUE).

Observe the regulations given by relevant sector standards regarding the override operation.

Make certain that appropriate procedures and measures (according to applicable sector standards) have been established to help avoid hazardous situations when activating the override operation.
