Master-Slave Parallel Operation
In Master-Slave parallel operation, the system is required to consist of same model
for all units and one of the PATs is made a master unit and connected to all other
PATs as slave units. The master is used to control the entire system.
The output current can be expanded using master-slave parallel operation (maximum
output current: the rated output current of a unit
×
number of units connected in parallel).
•
Maximum number of units in the system : 5 units including the master unit.
•
In Master-Slave parallel operation, the system m
u
st be
u
sed the same
model for all
u
nits.
•
In Master-Slave parallel operation, the master
u
nit and all of the slave
u
nits connected to the system m
u
st be set in the same phase inp
u
t
mode.
Three-phase inp
u
t mode :
(Max. o

u
t c
u
rrent) = (rated o
u
tp
u
t c
u
rrent of single
u
nit) X (n
u
mber of
u
nits
connected in the system)
Single-phase inp
u
t mode :
(Max. o
u
tp
u
t c
u
rrent) = (rated o
u
tp
u
t c
u
rrent of single
u
nit) X (n

mber of
u
nits
connected in the system) X 75 %
•
If the phase inp
u
t mode is not set in the same mode for the master
u
nit
and slave
u
nits, it may ca
u
se a damage to the
u
nit in the system.
6.1.1
Functions during Master-Slave Parallel Operation
The functions of the PAT during master-slave parallel operation are as follows:
Voltage display and current display
The voltage is displayed only on the master unit. It is not appeared on the display of
the slave unit.
The total value of current in which the number of unit connected in the parallel
operation is displayed in the current display part of the master unit. As for the
voltage display part, the voltage value which was set at as the last setting on the
master unit will be displayed.
If the actual number of connected units in Master-Slave Parallel Operation was
different from the setting condition which were set by CONFIG setting in the
“setting the number of units in Master-Slave Parallel Operation” (CF24), the current
value on the display will not be shown properly.
