Within each insertion/removal of resistances a certain amount of time (parameter Pb20) must
elapse in order to avoid simultaneous occurrences. Using the Hd13 parameter it is possible to
enable the thermal alarm of the resistance, which provides for the immediate shutdown of the
device.
Note. In order to exclusively utilize the resistances for purposes of post-heating it is
important to set PG14>0 and PG01=2.
6.8.3 Status of the resistance
Each of the three stages of the resistances can assume one of the following operating states:
1. Disabled: the stage of the resistances is not managed by the controller. The symbol
“…” will appear in the user interface while in this state.
2.
Off: the stage of the resistances is off. The word “OFF” will appear in the user
interface while in this state.
3. Waiting for startup: the stage of the resistances is about to startup, and is in queue for
a protection timetable. In this state in the user interface you will see written (and
flashing) “WON”.
4. Waiting for shutdown: the stage of the resistances is about to shutdown, and is in
queue for a protection timetable. In this state in the user interface you will see written
(and flashing) “WOF”.
5. On: the stage of the resistances is on. In this state in the user interface you will see
written “ON”.
6. Alarm: the resistances are blocked as a result of the relative thermal alarms. In this
state in the user interface you will see written “ALL”.
