P.4053 (threshold #1): 30.0 Vdc
•
P.4054 (delay #1): 0.5 sec
•
P.4055 (configuration #1): 0002 (bit 0 OFF, bit 1 ON)
•
P.4056 (threshold #2): 29.8 Vdc

P.4057 (delay #2): 0.5 sec

P.4058 (configuration #2): 0001 (bit 0 ON, bit 1 OFF)
The first threshold is used to activate the internal status related to the analogue input. Looking
at the configuration parameter you can see that:
•
Bit 0 OFF (checks that the measure is higher than the threshold).
•
Bit 1 ON (activates the internal
status in “out of threshold” condition).
The second threshold is used to deactivate the internal status related to the analogue input.
Looking at the configuration parameter you can see that:
•
Bit 0 ON (check that the measure is lower than the threshold).
•
B
it 1 OFF (deactivates the internal status in “out of threshold” condition).
So, with the previous programming, the controller activates the internal status related to the
analogue input when the measure is greater than 30.0 Vdc for 0,5 seconds; it deactivates the
internal status when the measure is less than 29.8 Vdc for 0,5 seconds.
Using the AND/OR logics, you can “copy” the internal status on a physical output.
HS315 provides one DC voltage analogue output. The maximum range of the output is +/-
10Vdc; it can be reduced to +/- 1VDC using the TR1 trimmer (near the JR terminals). This
output is normally used for the connection to the voltage regulator for traditional alternators,
or for the connection to the speed regulator for permanent magnets alternators. If a positive
only voltage range is required, you can use parameters P.0856 and P.0857 to limit the
hardware range.
It is possible to add one DANOUT module (through Can Bus link), that provides 4 additional
analogue outputs. These outputs can be configured as 0-20 mA, 4-20 mA, +/- 10Vdc or 0-20
Vdc.
All outputs are completely configurable.
The values of the outputs (percentage) is shown on page S.19.
HS315 provides one parameter for each analogue output, that allows the configuration of the
function of the output. See document [1] for the parameters list.
Analogue outputs can be used directly for sending commands to external devices, or to signal
working conditions.
The following table lists all the functions available:
Code Description. Curve Note
AOF.0000 Not used
AOF.0101 Used by PLC Output used by the internal PLC logic
AOF.0102 Managed by serial ports The controller does not control the output with its own internal logics, but
with the controls it receives through the serial ports.
