The function of this terminal depends on parameter P.4041:
•
AIF.0100. In this case the terminal is used as digital input (input 17). To activate the
input, connect its terminal to +BATT. To deactivate the input, leave the terminal
unconnected or connect it to GND.
•
AIF.1300. In this case, the terminal is used to provide the energizing current to the
battery charger of the engine. It is also used to measure the voltage provided by this
battery charger.
•
All other values: in this case the terminal is used as analogue input, with measuring
range 0-32VDC with respect to the power minus of the controller (GND).
The function of this terminal depends on parameter P.4009:
•
AIF.0100. In this case the input is used as digital input (input 13). Connect the terminal
JQ-2 to GND. To activate the input, connect the terminal JQ-1 to +BATT. To deactivate
the input, connect it to GND.
•
All other values: in this case the terminal is used as analogue input, with measuring
range +/-85VDC (differential mode between the two terminals).
You can also increase the number of analogue inputs by adding two optional
DITHERM/DIGRIN modules (three temperature input each) and one DIVIT module (four
Vdc/mA inputs), up to a total number of 10 additional analogue inputs. The expansion modules
must be connected to HS315 via CAN-BUS
In addition to the physical analogue inputs, the controller also operates 8 virtual analogue
inputs. The same are operated by the controller just as if they were physical inputs (with no
limitation), but the status of the virtual inputs is not acquired from the hardware, but it is
determ
ined through the software. In fact, by means of the “function” parameter of each virtual
analogue input, you can “copy” in the analogue input one of the internal measures made
available by the controller. See table in 5.6.6
The purpose of the virtual analogue inputs is double:
•
Allowing the issuing of warnings/locks related to the internal measures available.
•
Activating digital outputs based on the value of the internal measures available.
See example in par.5.6.6.
