Description

 

 

 

 

**UNMASK xxx

 

62

 

Used to read which bits in the status register have

 

 

been enabled to set bits in the fault register

 

 

(i.e.,which power supply conditions are defined as

 

 

faults). xxx is decoded using bit weights in Table

 

 

3-9.

 

 

 

 

FAULT?

**FAULT xxx

Used to read which bits have been set in the fault register. A bit is set in the fault register when the corresponding bit in the status register changes from inactive to active AND the corresponding bit in the mask register is set. Bits in the fault register are reset only after the fault register is read. xxx is decoded using bit weights in Table 3- 9.

ERR?

 

Enable or disable power supply’s ability to request

62

 

service from the controller for fault conditions.

 

 

UNMASK command defines which power supply

 

 

conditions are defined as faults. Initial Condition:

 

 

SRQ OFF

 

 

 

 

**SRQ 0 or

Used to read SRQ setting.

63

**SRQ 1

 

 

 

 

 

 

Used to initialize power supply to power-on state;

63

 

also resets the PON bit in the serial poll register.

 

 

The device clear interface message performs the

 

 

same function.

 

 

 

 

**ERR xx

Used to determine type of programming error

63

 

detected by power supply. A remote programming

 

 

error will set the ERR bit in the status register,

 

 

which can be enabled by UNMASK to request

 

 

service. See Table 3-10 for descriptions of error

 

 

codes.
