Retention (non-volatile data storage)
For more information visit: www.EatonElectrical.comMN05013003E 229
Changing the operating mode or the circuit diagram
When the operating mode is changed or the EZ circuit
diagram is modified, the retentive data is normally saved
together with their actual values. The actual values of relays
no longer being used are also retained.
Changing the operating mode
If you change from RUN to STOP and then back to RUN, the
actual values of the retentive data will be retained.
Modifying the EZ circuit diagram
If a modification is made to the EZ circuit diagram, the actual
values will be retained.
Changing the startup behavior in the SYSTEM menu
The retentive actual values in EZ will be retained irrespective
of the RUN MODE or STOP MODE settings.
Attention!
Even if the markers and function relays that were retentive
are deleted from the circuit diagram, the retentive actual
values remain when changing from STOP to RUN, and
when switching the device off and on. Should these relays
be used again in the circuit diagram, they will still have their
former actual values.
