2. Alarm Status Register:
The alarm status register records fault conditions occurring during power supply operation. Any set bit
in this register causes the ‘alarm’ bit in the operational status register to be set. Reading the register
does not change it’s content. The register is cleared by :DCL; command.
Table 5-6: Alarm status register content.
Notes: (*1) Since at each AC turn off the AC fail bit is generated and stored, it is recommended to
3. Error Codes Register:
The error codes register records errors that occurred during the programming of the power supply. Any
set bit in this register causes the ‘prog’ bit in the alarm status register to be set. Reading the register
does not change it’s content. The register is cleared by :DCL; command.

send a :DCL; command following application of AC voltage to the power supply, to clear the
alarm status register.
In case the OTP or OVP is triggered, the front panel control is disabled until the AC input is
recycled by turning the AC ON/OFF switch to OFF and after approx. 10 sec. to ON.
