6.1 Machine Status
Several procedures exist for switching the unit ON and OFF:
1) Using the dedicated ON/OFF key (this function is enabled via parameter PH05).
Switching ON – Press the dedicated key for about 2 seconds: if all other enabled functions
are present, the machine switches itself ON.
Switching OFF – Press the dedicated key for about 2 seconds: the machine switches itself
OFF.
2) Using the ON/OFF command from digital input (this function is enabled via parameter
PH07).
Switching ON – Close the remote ON/OFF contact: if all other enabled functions are
present, the machine switches itself ON.
Switching OFF – If the remote ON/OFF contact reveals itself to be open, the machine
switches itself “OFF from digital input”, which is indicated by “OFF D”.
3) Using a supervisory protocol (this function is enabled via parameter PH09).
Switching ON – Activate via protocol the switching ON status: if all other enabled functions
are present, the machine switches itself ON.
Switching OFF – If the ON status is disabled via protocol, the machine switches itself “OFF
by supervisory protocol”, which is indicated by “OFF S”.
The ON/OFF status from key press has priority over the two others; indeed, OFF statuses from
digital input and supervisory protocol are only accessible if the machine has been enabled by key
press.
A machine that has been switched OFF by digital input can:
⋅
switch to key-press OFF status (by pressing the dedicated key);
⋅
switch to supervisory OFF status (if the digital input is open and the supervisory OFF status
has been set);
⋅
switch itself ON (if the digital input is closed and the supervisory OFF status has not been
set).
A machine that has been switched OFF by supervisory protocol can:
⋅
switch to key-press OFF status (by pressing the dedicated key);
⋅
switch to digital-input OFF status (if set via supervisor and if the digital input is open);
⋅
switch itself ON (if the digital input is closed and the supervisory OFF status has not been
set).
The machine ON/OFF key is the ESC key.
The remote ON/OFF input (if present) is configured via the linked parameter Hd01.
