When a protection occurred in the slave unit, please press
to clear fault in corresponding slave unit and
in master unit. When protection occurred in master unit only, just press
on master unit to clear fault.
Possible protections and fault in parallel operations are listed as follows:
Table 3-7 Master-slave parallel protection
Protection Display
Explanation
Parallel communication normal, symbol is white background
and not blinking
Parallel communication error, symbol is red background and
blinking
Indicates the fault slave unit code, requires user to press
to clear the fault protection
---------------------------------------------------------------------------------------------------------------------------
1. Set slave unit first, so as to avoid master unit communication error;
2. Multiple power supplies have been set as master unit leads to parallel operation failure;
3. If cable in “Share” port is not connected or fall off, then although the specifications are
updated in accordance with number of slave units when the master unit turns on master-slave
parallel control, the actual output will be inconsistent with the master unit configuration due
to “Share” port fault.
4. The external programming of the master unit is effective to the whole group.
5. When a power supply is configured as slave unit, the previous set protection value in
“Protection” are canceled. To resume you have to reset its values.
6. It is prohibited for paralleling different power supply models, because this will damage the
power supplies.
