6.1 State of the unit
There are several unit switch-on/off procedures:
1) Via the relevant ON/OFF key
Switch-ON: press the relevant key for about 2 seconds, if all the conditions are fulfilled the
unit starts working (“ON” mode).
Switch-OFF: press the relevant key for about 2 seconds, the unit stops working (“OFF”
mode).
2) Using the Start/Stop from digital input control (parameter, PH05=1)
Switch-ON: close the contact, if all the conditions are fulfilled the unit starts working (“ON”
mode).
Switch-OFF: if the contact is open the unit stops working (“OFF from Start/Stop” mode).
3) Via Supervision protocol (parameter, PH06=1)
Switch-ON: activate the switch-on state from protocol, if all the conditions are fulfilled the
unit starts working (“ON” mode).
Switch-OFF: if deactivated by switch-on state protocol the unit stops working (“OFF from
Supervisor” mode).
The ON/OFF status from key has priority with respect to the other two. In fact the ON/OFF states
by digital input and supervision protocol can only be reached with machine in “ON” mode.
A machine switched-off by Start/Stop digital input can:
⋅
pass to the OFF state from key (by pressing ESC).
⋅
pass to the OFF state from supervisor if the OFF condition from digital input returns and the
OFF state is set by supervisor.
⋅
ass to the ON state if the ON condition from digital input returns and the OFF state is not set
by supervisor.
A unit switched-OFF by supervision protocol can:
⋅
Move to the OFF state by key (by pressing ESC key).
⋅
Move to the OFF state from digital input if the OFF condition from supervisor ceases and
the OFF state from digital input is triggered.
⋅
Move to the ON state if the OFF condition from supervisor ceases and the OFF state is not
present from digital input.
The unit ON/OFF key is the ESC key pressed for about 2 seconds.
The remote Start/Stop input (when present) can be configured using the parameters:
- PH05: Enables the function
- PH52: Sets the NC, NO logic for the digital contact
