6.1 Unit status
There are additional procedures for the start-up/shut-down of the unit:
1) Using the On/Off key (parameter, PH05=1)
Startup: press the related key for approximately 2 seconds: if all the other enabled
conditions are present, the machine will turn “ON”.
Shutdown: press the related key for approximately 2 seconds: the machine will turn
“OFF”.
2) Using the On/Off command from the Digital inputs (parameter, PH07=1)
Startup: close the remote On/Off contact: if all the other enabled conditions are
present, the machine will turn “ON”.
Shutdown: if the remote On/Off contact opens, the machine will turn “OFF from
Digital inputs” (as also indicated by the dictation “OFF_D”).
3) Using the supervision protocol (parameter, PH09=1)
Startup: activate from protocol the startup status: if all the other enabled conditions
are present, the machine will turn “ON”.
Shutdown: if the startup status becomes deactivated from the protocol, the machine
will turn “OFF da protocollo di supervisione” (OFF from supervision protocol) (as
also indicated by the dictation “OFF_S”).
The status of the On/Off key has priority with respect to the other two keys. In fact, the
