too high and could damage
amplifier.
"ALC or Impedance
must be off"
Conflict between ALC and
programmable impedance
mode.
Turn off ALC to use
programmable impedance.
Turn
off programmable impedance to
use ALC.
"Output relay must be
open”
Attempting to change
voltage range while output
relay is closed.
Open output relay first, then
change range. This ensures the
load is physically disconnected
during voltage range change.
Over voltage protection
trip.
Output voltage exceeds voltage
range value. Check sense
connections if external sense
mode is used.
Maximum available peak
current capability of power
source exceed
ed.
Note: Firmware rev 4.52 or
higher.
This error will trip if
PONS:CURR:PEAK:PROT
status is set to 1 and the peak
current drawn by the load
exceeds the maximum specified
peak current capability for more
than 30 seconds. To avoid this
error, reduce the load on the
power source or upgrade to a
larger power configuration.
Frequency is out of
allowable range.
Indicates a problem with
programmable controller.
“DC component
exceeds limit”
The waveform selected
contains a DC offset that
exceeds the AC mode
capability.
Contact customer service.
“Warning negative
power near limit”
Approaching limit on the
amount of power that can
be fed back into the supply
by an active load. This is a
warning only.
Stop increasing power feedback
into the power supply. Typically
occurs when using AC
inverters. If power increases
further, an error 32 will be
generated.
Too much power fed back.
Power source output
disconnected.
Reduce the amount of power
being fed back into the power
source.
