6-3. One-Control series operation (excluding PSF-400L2)
The PSF Series power supply units are capable of one-control series
operation of up to two units, including the master unit. When
executing one-control series operation using master units, the slave
unit should be set properly in advance.
◆
For the setting procedures, see Section
“5-5-10. Master-slave
function
” above.
Connect the master and slave units with the optional series signal
cables OP-22S. The joint kit JK-10 is also available by option.
Use it as the necessity requires.
In one-control series operation, voltage is only displayed on the slave
unit (when output is turned on).
The voltage displayed on the master or slave unit is the output voltage
of the unit alone.
◆
See Section 2
“SPECIFICATIONS” for the displayed items and
setting resolution in one-control operation.
Output depends on the master unit. When the OUTPUT key of the
master unit is thrown, output of the slave unit is turned on automatically.
Connect the master and slave unit with the optional OP-22S.
※
Improper wiring or setting may cause failures.
Recheck the setting before starting one-control operation.
