Configuring inputs
All the inputs can be configured by entering the appropriate values into parameters I01-I10. To configure a digital input, enter a value
less than 100; to configure an analogue input, enter a value equal to or greater than 100.
The value 0 indicates that no function is associated with the input.
All 10 inputs can be used as digital inputs, but only some (IN1, IN2, IN3, IN4, IN5, IN6 and IN7 on EV3 HRV; IN1, IN2, IN3, IN4, IN5,
IN9 and IN10 on EVD HRV) can be configured as analogue inputs.
Inputs IN1 and IN2 are universal, configurable through parameters I13 and I14, whereas the other analogue inputs are NTC/digital
inputs.
To configure a digital input, you must assign a number to the corresponding parameter consisting of an absolute value that indicates
the function and a sign that indicates the polarity:
Negative= Normally closed (NC)
Positive= Normally open (NO)
If an unexpected value (see table) is set in parameters I01-I10, the value will not be rejected by the controller, but no function
will be assigned to the input. If two or more inputs are configured with the same value, only the input with the highest index will be
used. For example, if both IN4 and IN6 are configured for a room probe, the value associated with input IN4 will be ignored and only
the value associated with input IN6 will be used.
