5-24 Basic Operation PLZ-4W
5.12 Short Function
The short function is used to immediately set the maximum current (CC mode) or
minimum resistance (CR mode).
When the short function is enabled, the short signal output of the J1 connector is
turned on. The short signal output terminal is connected to a relay contact (30 VDC/
1 A) and can be used to drive an external relay for high current to short the load
input terminal.
For a description of the J1 connector, see “J1 and J2 Connectors” in section 6.8,
“External Control.”
• Be sure to use a dedicated driver circuit to drive the relay for high current.
