The status contained in "message" may be any of the following for non-CNF messages:
SYNTAX
ERROR
VOLT
RANGE
ERROR
FREQ
RANGE
ERROR
CURL
RANGE
ERROR
PANG
RANGE
ERROR
The response of the power source under a short circuit condition is as follows:
F07ACS01<SP>(DEV): <SP> OUTPUT CH01&02&03 VOLT FAULT <CR> <LF>
A setup string can always be followed by another string with the STA OP-code. In the event of a syntax, range or
system error, an error message will be returned to the bus controller when the power source is addressed to talk. The
value of the last parameter in a setup string is the one displayed on the front panel of the power source.
3.8.7
DISCRETE FAULT INTERRUPT
A discrete fault condition is one that would pose a hazard to equipment or personnel. A Discrete Fault Interrupt (DFI) is
supplied with the MT power source option. The DFI relay contacts are connected to the BNC connector, J3, on the
power source rear panel. Under normal operating conditions, the DFI relay contacts are open; when a fault is detected,
the contacts close. The user may connect any type of indicator or alarm circuit to the DFI connector provided the
applied signal is limited to 0.1 amps and 26 volts.
The conditions which will cause the discrete fault interrupt are listed in Table 3-18.

DISCRETE FAULT INTERRUPT CONDITIONS
FAULT CONDITION
OVERLOAD OUTPUT
PROGRAMMABLE CURRENT
OVERTEMPERATURE
CONTROLLER FAILURE
POWER OFF
The full rated power capability is exceed on any phase where programmed
output voltage is not maintained.
The load draws more current than the programmed current limit point on
any phase.
Excess heatsink temperature in power supply or output amplifier due to
high ambient temperature or internal component failure.
The AC Power Controller has a CPU failure which is monitored by a watch
dog timer.
Power remains off - input breaker off.
