Software Shutdown - gefran GFX4 Configuration And Programming Manual

SOFTWARE SHUTDOWN

Running the software shutdown procedure causes the following:
1) Reset of Autotuning, Selftuning and Softstart.
2) Digital input (if present) enabled only if assigned to SW shutdown function.
3) In case of switch-on after SW shutdown, any ramp for the set (set gradient) starts from the PV.
4) Outputs OFF: except for rL.4 and rL.6 which are forced ON.
5) Reset of HB alarm.
6) Reset of LBA alarm.
7) The Heat and Cool bit on the state word STATUS_STRUMENTO and POWER are reset.
8) At shutdown, the current power is saved. At switch-on, integral power is recalculated as the difference between saved power
and proportional power; this calculation is defined as "desaturation at switch-on."
9) The state of alarms (AL1...AL4, ALHBTA1...ALHBTA3) is reset.
