The configuration of the terminals JH / JG is done through parameters P.9611 (JG-1), P.9612
(JG-2), P.9613 (JG-3), P.9614 (JG-4), P.9615 (JH-1), P.9616 (JH-2), P.9617 (JH-3) e, P.9618
(JH-4); the following values can be used to configure the measurement of DC voltages:
Value Description
013 DC voltage for the auxiliary source (+)
014 DC voltage for the auxiliary source (-)
023 DC voltage for the generator (+)
024 DC voltage for the generator (-)
033 DC voltage for the battery (+)
034 DC voltage for the battery (-)
043 DC voltage for the loads (+)
044 DC voltage for the loads (-)
051 Common terminal (-) for DC voltages
052 Common terminal (+) for DC voltages
M/- 105 Vdc can be applied between JH / JG terminals and GND.
If it is necessary to acquire higher DC voltages, external DC/DC voltage converters must be
used; use parameters P.9647 and P.9648 to define its transformation ratio.
If no AC measurements are required, we suggest using
the eight terminals of JH / JG in “pure
different
ial” mode.
If the AC voltages of the generator are required (three-phases), the terminals JG are used for
those measurements: use one terminal of JH as “common negative” of DC voltages, and the
other three terminals to acquire three DC voltages. The fourth DC voltage can be acquired
using JQ.
If the AC voltages of the auxiliary source are required (three-phases), the terminals JH are
used for those measurements: use one terminal of JG as “common negative” of DC voltages,
and the other three terminals to acquire three DC voltages. The fourth DC voltage can be
acquired using JQ.
If the AC voltages of both generator and auxiliary source are required, we suggest connecting
them in single-phase mode: the terminals JH-3, JH-4, JG-3 and JG-4 will be used for AC
voltages. Use one of the remaining termin
als as “common negative” of DC voltages, and the
other three terminals to acquire three DC voltages. The fourth DC voltage can be acquired
using JQ.
At least, the DC voltage of the plant battery must be connected to the controller (if not, the
controller activates the warning W273).
HS315 can measure up to four DC currents (generator, plant battery, loads and auxiliary
source). The measurement of the loads DC current is not mandatory: HS315 can calculate it
as the sum of the other currents.
As a rule, the current is positive when:
•
Supplied by the generator.
