1470 AR Mode 1: Auto Restart
Caution: when Auto Restart is selected the motor may run unexpectedly.
In Auto Restart mode, once the AR feature becomes active it monitors all possible trip sources. Once all trip sources are inactive the AR feature
starts the programmed delay. Once the delay timer expires the AR feature attempts to reset the trip and to restart the motor.
The AR feature will not restart the motor if it was not running at the time of the trip, nor will it restart the motor if the run signal has been removed at
any time since the trip, (even if it is subsequently re-applied). When a motor restart will not be attempted the AR feature will act as if it had been
configured for
Trip Reset only. If a motor restart will be attempted the parameter 1508 AR Restart Pending is set TRUE.
Each time a restart is attempted the value in
1509 Restarts Remaining is decremented. Once this value reaches zero, any further trip selected for
auto restart will cause the AR feature to disable itself.
1470 AR Mode 2: Auto Start
Caution: when Auto Start is selected the motor may run unexpectedly.
In Auto Start mode, once the AR feature becomes active it monitors all possible trip sources. Once all trip sources are inactive the AR feature starts
the programmed delay. Once the delay timer expires the AR feature attempts to reset the trip and to restart the motor.
The AR feature will attempt to start the motor even if it was not running at the time of the trip, as long as the Sequencing Logic parameter
0644
Control Word is configured to run, (typically bits 0, 1, 2 and 3 all set), see Appendix B: Sequencing Logic.
In this mode the parameter 1508 AR Restart Pending is set TRUE. Each time a restart is attempted the value in 1509 Restarts Remaining is
decremented. Once this value reaches zero, any further trip selected for auto restart will cause the AR feature to disable itself.
Recovery from Self Disabled state
The AR feature will remain in the Self Disabled state indefinitely. It may be re-activated by the trip condition being reset by some other means, (ie.
Manually by pressing the stop key on the GKP, or remotely using trip reset). Alternatively the AR feature may be re-enabled by setting
1469 AR Enable to FALSE then back to TRUE.
Indication
When the AR feature is activated the parameter 1507 AR Active is set TRUE.
While a restart is pending the parameter 1508 AR Restart Pending is set TRUE. In addition the green LED illuminating the run key on the GKP will
flash.
All indicators are reset once the restart, (or trip reset), attempt has been completed or if the AR feature is disabled.
