Figure 902: Initiation during discrimination time - AR function goes to lockout
The discrimination time starts when the close command
CLOSE_CB
has been given.
If a start input is activated before the discrimination time has elapsed, the AR
function goes to lockout. The default value for each discrimination time is zero. The
discrimination time can be adjusted with the
Dsr time shot 1…4 parameter.

9.9.4.5 Sequence controller
When the
LOCKED
output is active, the AR function is in lockout. This means
that new sequences cannot be initialized, because AR is insensitive to initiation
commands. It can be released from the lockout state in the following ways.
• The function is reset through communication with the
RecRs parameter. The
same functionality can also be found in the Clear menu (DARREC1 reset).
• The lockout is automatically reset after the reclaim time, if the
Auto lockout reset
setting is in use.
