If any of the areas is not valid, the normal operating sequences are not carried out until the
operator presses t
he “ENTER + EXIT” buttons: in fact, the situation must be taken note of,
because it may cause malfunctions (for example, imagine what would happen if the invalid
area were the one of the parameters) Only when the operator presses “ENTER + EXIT” the
controller reloads the default settings for the data stored in the invalid areas: it means that, in
the event the
controller is shut off without pressing “ENTER + EXIT”, next time you turn it on
you will get again the invalid memory report.
HS315 can collect data from special batteries equipped with a communication interface. Up to
now, it can use one of its serial ports to connect to the control cards inserted into some
batteries, if they support the Modbus RTU protocol (the electronic card works as a slave-
server, HS315 function as a master-client).
The following parameters allow you to configure this function:
•
P.9761: Selects the battery model. Value "0" disables this function. Other supported
values are:
o
1: FIAMM 48TL200.
o
11: LG M4860P2S.
o
21: SAFT EVOLION 782672
•
P.9762: it determines which values acquired from the battery control card should be
used by the HS315 instead of their own. It's a bit managed parameter:
o
Bit 0: charge level.
o
Bit 1: temperature.
o
Bit 2: current.
o
Bit 3: voltage.
•
P.9763: Indicates how many batteries (identical to each other) are connected in
parallel. In fact, these batteries have quite reduced capacities for a real plant: it will
often be necessary to connect more than one in parallel. HS315 manages the
communication with up to 16 batteries. The batteries must have different (but
contiguous) Modbus addresses. The lowest Modbus address must be set in
parameters P.0452 (if using the first serial port) or P.0472 (if using the second serial
port).
By default, only the charge level and the temperature are selected (so the voltage and charge
current will still be measured by HS315).
If you are using the first serial port (RS232) to connect to the battery, set P.0451 to "3". If you
are using the second serial port (RS485), set P.0471 to "3". Note: If both parameters are set
to "3", the card uses the first serial port to connect to the battery.
If you configure the connection to the battery, HS315 activates the W228 warning if it does not
receive battery feedback consecutively for 5 seconds (for each single battery).
It is a 200 Ah salt battery, which is equipped with a BMS system that regulates the charging.
Its serial port is normally configured with the Modbus/ASCII protocol. However, you can
change the settings with a PC software provided by the manufacturer. To use it with HS315,
set it as Modbus/RTU, 8 bits, no parity, 2 stop bits. The pre-assigned Modbus address is "2".
HS315 acquires the following data from the battery:
