CAUTION Improper wiring or settings may cause failures.
Recheck the settings before starting frame control
operation.
If the load cables of a slave unit are disconnected,
excessive voltage is applied to the slave unit
instantaneously and a ―HArd‖ alarm occurs.
Check if the cables are connected properly. Repair
improper connections. The master unit displays
the total current. If the actual value is remarkably
different from the set current and/or output
current, improper power may possibly be set in the
setting shown in the Master-slave function chapter
on page 70. Recheck the set power.
When using frame link-controlled parallel
operation, the current indicated on the master unit
may fluctuate due to the influence of the load wire
resistance. In such cases, use the optional
connection kit, PSB-003 (Horizontal Installation
Connection Kit), PSB-004 (Vertical Installation
Connection Kit) or a low-impedance-load wire.
Use the PSB-2400L as the master unit when
controlling the PSB-2400L and PSB-2800L using the
the frame link control method.
