High Power Electronic Load 63200A Series Operation & Programming Manual
3-12
For parallel, simply set the MASTER and it can control the loading on the MASTER and
SLAVE in the parallel group.
For synchronization, the loading values need to be set separately for all MASTER and
SLAVE; however, the synchronization of LOAD ON/OFF is controlled by MASTER.
ADDRESS
In the SYSTEM BUS network, all Electronic Load has to set a communication address
without duplicates. The setting range is 1~10 and the default is 1.
Terminator
It sets the terminal resistor required for SYSTEM BUS. The terminator function needs to be
enabled on the first and last Electronic Load in the SYSTEM BUS network. As to the
devices in between, they need to be set to OFF. It can set to ON(1)/OFF(0) and the default
is OFF(0)
.
SYNC MODE
Set the standalone device to be MASTER or SLAVE in a synchronization group. It can set to
DISABLE(0), MASTER(1), SLAVE(2) and the default is OFF(0).
PARA MODE
Set the standalone device to be MASTER or SLAVE in a parallel group. It can set to
DISABLE(0), MASTER(1), SLAVE(2) and default is OFF(0).
PARA. NUM
Set the number for parallel at a maximum of 10. The setting of PARA. NUM is
Slave and the set number should be the same as the actual paralleled number.
INITIAL
It initializes for parallel. When ON is selected for INITIAL, the parallel communication will be
connected and disconnected when OFF is selected.
CAUTION
1. The terminator function needs to be enabled on the first and last
Electronic Load in the SYSTEM BUS network. As to the devices
in between, they need to be set to OFF. It could cause bad
communication if the terminators are set wrong. When the
63200A Series Loads are paralleled, the Address must start from
1 to 10 sequentially without any skip. For example, if two 63200A
Series Loads are paralleled, the first one is Master and the
Address has to be 1, while the second one is Slave and the
Address must be 2 with no number skipped.
2. Set NONE for the unit not to be paralleled. For instance, set the
6
th
and the unit followed to NONE when paralleling 5 units;
otherwise, connection error may occur during parallel connection.
GO/NG Spec. Testing 3.5.4
The Electronic Load GO/NG testing function allows the user to program the spec of voltage,
current and power. Turn on the SPEC testing function during testing and the testing result
can be displayed simultaneously. GO will show if the SPEC is met and NG will appear if not.
