The structure of status data

 

TOP

Status register, Fault register, and Fault Unmask Register

Bits “1” and “0” of the status register and the status enable register represent “set” and “reset,” respectively. The fault register is read and reset using FAU?.

 

Bit Bit Name Description
7 ALM (Alarm) Indicates that an alarm has occurred (except for OHP and OVP)
6 OHP (Over heat protection) Indicates that the overheat protective (OHP) circuit has been activated.
5 OVP (Over voltage protection) Indicates that the overvoltage protective (OVP) circuit has been activated.
4 OUT Indicates that outputs are OFF.
3 NOT USED Not used in the controller.
2 NOT USED Not used in the controller.
1 C.C (Constant current) Indicates that the connected power-supply unit is operating at a constant current.
0 C.V (Constant voltage) Indicates that the connected power-supply unit is operating at a constant voltage.
