The controller reports the failure of the temperature sensor ("W213 - broken wire") if parameter
P.9636 is different from zero and the resistance measurement exceeds 333 ohms. The same
warning is also activated if voltage or current temperature compensation is required, but
temperature measurement is not available (for example if P.9636 is set to 0).
Moreover, HS315 provides the following parameters:
•
P.9662
(“Voltage compensation due to temperature): it is defined as mV/°C
for a
single battery cell . It applies to the following parameters:
o
P.9676
(“End charge (full) voltage for BULK mode”).
o
P.9683
(“End charge (standard) voltage for BULK mode”).
o
P.9679
(“Charge (full) voltage in FLOAT mode”).
o
P.9686
(“Charge (standard) voltage in FLOAT mode”).
o
P.9665
(“Voltage for detecting the end of discharge”).
If set to zero, the controller will not compensate any voltage threshold.
Note: the controller a
ssumes that the battery’s internal cells have a rated voltage of 2
volts (lead-acid batteries). If you want to use temperature compensation for other
types of batteries, always set the compensation to apply every 2 Volt DC.
•
P.9663
(“Charge current compensation due to temperature”): it is defined as a
percentage of the rated capacity (P.9642) per °C. It applies to the following
parameters:
o
P.9675
(“Charge (full) current in BULK mode”).
o
P.9682
(“Charge (standard) current in BULK mode”).
o
P.9677
(“End charge (full) current for ABSORBTION mode”).
o
P.9684
(“End charge (standard) current for ABSORBTION mode”).
If set to zero, the controller will not compensate any current threshold.
For the thresholds involved in temperature compensation, in program function HS315 shows,
in addition to the programmed value, the real voltage/current threshold, adjusted by the
temperature.
The charge process can be started for two reasons:
•
For low battery voltage. Parameter P.9665
(“Voltage for detecting the end of
discharge
”) allows to select the voltage (% of P.9641, adjusted by temperature) under
which the charge process is required. The default value is 87.5% (42 Vdc for a rated
48 Vdc battery).
•
For low remaining charge. During the discharge process, HS315 continuously
estimates the remaining charge level (Ah). Parameter P.9664
(“Discharge limit”)
allows to select the remaining charge level (percentage of the rated capacity) under
which the charge process is required. The default value is 0.10C (10% of the rated
capacity).
Parameter P.9661
(“Monitoring mode for charge status”) allows to select which method must
be used:
1. Voltage only.
2. Energy only (remaining charge level).
