In order to use the DI8 as a normal digital input, program the designated function at P0270, and connect a
resistor, ranging from 270 to 1600 Ω, in series with the contact (

If the function
‘Parameterization Disabling’
is programmed and the correspondent DIx in +24 V input is
closed, then parameter changes are not allowed, regardless of P0000 and P0200 settings. When the DIx
input is open, parameter changes are conditioned to P0000 and P0200 settings.
‘RL2 and RL3 Timer’
: this function acts as a timer to activate and deactivate the relays 2 and 3 (RL2 and
RL3). When the timer function for the relay 2 or 3 is programmed at any DIx, and a transition from open to
closed occurs, the programmed relay will be activated with the delay set in P0283 (RL2) or P0285 (RL3). When
a transition from closed to open occurs, the programmed relay will be deactivated with the delay adjusted in
P0284 (RL2) or P0286 (RL3). After the transition of the DIx, either for activating or deactivating the programmed
relay, it is necessary that the DIx remains closed or open during at least the time set in P0283/P0285 and
P0284/P0286. Otherwise, the timer will be reset. Refer to the
.
Note:
In order to
enable that function it is also necessary to program P0279 and/or P0280 = 29 (Timer).
The ‘Ventilation OK’ function generates an inverter ventilation fault (F0048).
