6-7-2. Service Request: Enable and Event Registers
The conditional Registers are continuously monitored. When a change is detected in a register bit which is enabled,
the power supply will generate an SRQ message.
The SRQ message is: "!nn" terminated by CR, where the nn is the power supply address.
The SRQ will be generated either in Local or Remote mode.
◆
Refer to Tables 6-10 to 6-13 for details of the Enable and Event registers.
1. Fault Enable Register
The Fault Enable Register is set to the enable faults SRQs.
Table 6-10: Fault Enable Register
BIT Enable bit name Fault symbol Bit Set condition Bit Reset condition
0(LSB) Spare bit SPARE
User command:
“FENA nn” where nn is
hexadecimal
User command:
“FENA nn” where nn is hexadecimal
(if nn=”00”, no fault SRQs will be
generated).
1 AC Fail AC
2 Over Temperature OTP
3 Foldbck FOLD
4 Over Voltage OVP
5 Shut Off SO
6 Output Off OFF
7(MSB) Enable ENA
2. Fault Event Register
The Fault Event will set a bit if a condition occurs and it is enabled. The register is cleared when FEVE? , CLS
or RST commands are received.
Table 6-11: Fault Event Register
BIT Enable bit name Fault symbol Bit Set condition Bit reset condition
0(LSB) Spare bit SPARE

occurs and it is enabled.
The fault can set a bit,
but when the fault clears
the bit remains set.
Entire Event Register is cleared when
user sends “FEVE?” command to
read the register.
“CLS” and power-up also clear the Fault
Event Register.

7(MSB) Enable ENA
3. Status Enable register
The Status Enable Register is set by the user to enable SRQs from changes in power supply status.
Table 6-12: Status Enable Register
BIT Status name Status symbol Bit Set condition Bit reset condition
0(LSB) Constant Voltage CV
User command:
“SENA nn” is received,
where nn is hexadecimal
bits.
User command:
“SENA nn” is received, where nn is
Hexadecimal bits.
If “nn”=00, no SRQ is sent where there
is a change in Status Condition Register.
