The individual bits are set on the occurrence of the event. A general clear is performed after readout.
If the Output voltage was permanently switched off by exceeding V

or I

(ENABLE KILL resp. Current trip),
or INHIBIT respectively, the error bits (REG1ER_, EXTINH_, ILIM_) have to be reset by reading

before an output voltage can be set again.
Start voltage change (BA + 0x34 / Ba + 0x38)
A change in the output voltage of set voltage (BA + 0x04 / BA + 0x08) is performed by reading these registers.
Writing to the registers stores the data as new set voltage (V
set
≤
V
max
) and starts the voltage change.
The change of output voltage is blocked, if the conditions are unavailable to start voltage change corresponding
these description.
Command execution can be checked by reading status register 1 (BA + 0x00). The bits D14 (channel B), D6
(channel A) respectively are set on start of voltage change. Actual voltage reaching the set voltage is flagged by
the bits D10, D2 of status register 2 (BA + 0x30) respectively. An interruption of the voltage change (e.g.
external INHIBIT is active) is also ascertainable.
Module identifier (BA + 0x3C)
D15 .. D0 4 digit serial number, BCD coded
Current software limit (BA + 0x44 / BA + 0x48)
The maximal output current per channel corresponding current resolution. If the output current exceeds the
programmable limit, the output voltage will be shut off permanently by the software (Current trip). The Current
trip reaction time is lessen to 60 ms.
Writing to the registers with maximal output current = 0, not a current trip will be programmed.
Hardware maximum output current limit (I
max
) worked independently of programmable current software limit.
