5.10 State of the unit

There are several procedures for switching the unit on/off:
1) Via the relative On/Off key
Switch-on: press the relative key for about 2 seconds: if all of the other conditions enabled
are present, the machine goes to "ON".
Switch-off: press the relative key for about 2 seconds: the machine goes to "OFF" mode.
2) Via the On/Off from digital input control (ONOFF d.input = 1 parameter)
Switch-on: close the remote On/Off contact: if all of the other conditions enabled are
present, the machine goes to "ON".
Switch-off: if the remote On/Off contact is open, the machine goes to "OFF from digital
input" (also signalled by "OFF digital in.").
3) Via supervision protocol
Switch-on: to activate the switch-on state from protocol: if all of the other conditions
enabled are present, the machine goes to "ON".
Switch-off: if the ignition state is deactivated from protocol, the machine goes to "OFF from
supervision protocol" (also indicated by "OFF supervisor").
The On/Off state from key has priority with respect to the other two. In fact, the On/Off states from
digital input and supervision protocol can only be reached with machine on from key.
A machine switched off from digital input can:
⋅
pass to the OFF state from key (by pressing the ESC key).
⋅
pass to the OFF state from supervisor if the OFF condition from digital input returns and the
OFF state from supervisor is set.
⋅
pass to the ON state if the OFF condition from digital input returns and the OFF state from
supervisor is not set.
A machine switched off from supervision protocol can:
⋅
pass to the OFF state from key (by pressing the ESC key).
⋅
pass to the OFF state from digital input if the OFF condition from supervisor returns and the
OFF state from digital input is tripped.
⋅
pass to the ON state if the OFF condition from supervisor returns and the OFF condition
from digital input is not present.
The machine On/Off key is the ESC key, pressed for about 2 seconds.
The remote On/Off input (when present) can be configured via the parameters:
- ONOFF D input: Enables the function
- D In 6 : Sets the NC, NO logic for the digital contact
5.10.1 OFF state due to alarm
When the machine is on, a further state exists OFF due to alarm, which switches the nit and all
devices off until the alarm condition has been reset. If digital consent is missing in this state from
