The four inputs configuration can be done by means parameters P.9619, P.9623, P.9627 and
P.9631. Those are the possible values for the parameters:
Value Description
011 DC current for the auxiliary source
021 DC current for the generator
031 DC current for the battery
041 DC current for the loads
The current/voltage ratio (A/V) of the sensors can be adjusted by means parameters P.9601,
P.9602, P.9603 and P.9604. Therefore, it is possible to use different size sensors in the same
plant.
The measurement input JU of the controller are factory calibrated by SICES. However, it is
possible to calibrate also the external sensors. Use the following parameters:
Input Gain (mV) Offset - (mV)
1 P.9622 P.9620 P.9621
2 P.9626 P.9624 P.9625
3 P.9630 P.9628 P.9629
4 P.9634 P.9632 P.9633
The
parameters of the “gain” column allow the real calibration of the inputs: if the measurement
shown by the controller is lower than the real current, increase the “gain” parameter and vice-
versa.
The parameters of the “offsets” columns, instead, allow the compensation of the residual
voltage on the sensors when no current flows through them. The residual voltage on a Hall
sensor is different if the last flowing current was positive or negative: this is the meaning of the
two “offset” parameters.
HS315 can acquire a PT100 sensor to measure the temperature of the plant battery. This
temperature is used for diagnostic purposes, but also to compensate the charging
voltage/current during the charge process (see the description of the charge process).
The measured temperature is shown on page M.02.
