Locking diagnostics parametering
NOTE: The ACT output is created with a logical AND from TRIGR and UNLOCK. REACT must not be active in this situation. Other inputs (e.g. ED) have no effect on this.
Representation of the relevant inputs for the ACT output:
If the TRIGR input (trigger signal) becomes "1" and UNLOCK does not, the internal timer will be started.
When the preset time at the DTIMEL input has expired, the ERR output will display an error that remains active until TRIGR becomes "0", ACT becomes "1", or diagnostics is deactivated.
If the trigger time DTIMEL is entered as "0", an error message is displayed as soon as an error situation occurs.
A detailed example showing the process of locking diagnostics can be found in the locking diagnostics timing diagram.
An active ACT output terminates the locking diagnostics and starts the action diagnostics.
Action diagnostics parametering
If the ACT output becomes "1" and REACT does not, the internal timer will be started.
If the action becomes inactive during processing, the monitoring time is stopped/reset or in the event of an error, the error processing is stopped.
When the preset time at the DTIMEA input has expired, the ERR output will display an error that remains active until ACT becomes "0", REACT becomes "1", or diagnostics is deactivated.
If the tolerance time DTIMEA is entered as "0", an error message is displayed as soon as an error situation occurs.
An example for the process of lock/action diagnostics is given in the timing diagram.
Timing diagram
Locking/action diagnostics timing diagram
(1) The internal timer starts when TRIGR is "1" and UNLOCK is "0". (2) If the internal timer reaches the DTIMEL value, an error is reported. (3) If UNLOCK becomes "1", the error will be cancelled, the internal timer is stopped and reset, and ACT becomes "1". Activating the action causes a switch to the action diagnostics. As the reaction has not yet occurred, the internal timer is started. (4) If the internal timer reaches the DTIMEA value, an error is reported. (5) If TRIGR becomes "0", the error will be cancelled, the internal timer is stopped and reset, and ACT becomes "0". (6) When ED is "0", the function block is reset and is restarted in the locking diagnostics when ED is "1". (7) When UNLOCK is "1", the internal timer is stopped and reset, and ACT becomes "1". Activating the action causes a switch to the action diagnostics. As the reaction has not yet occurred, the internal timer is started. (8) If REACT becomes "1", the error will be cancelled, the internal timer is stopped and reset, and ACT becomes "0". It is switched again from the action diagnostics to the locking diagnostics.
