California Instruments
Cause
Current limi
t exceeded.
Amplifier heat sink temp.
too high.
Could not sync to external
syn signal.
c
Initial settings could not be
recalled at power-up.
Hardware configuration
settings could not be
recalled at power-up.
Memory corrupted during
power-up.
Calibration data lost
during power-up.
One or more transient list
parameters missing.
Peak voltage exceeds
internal bus voltage
Time needed to slew to
final value is less than
dwell time.
Operation requested not
available while transient is
running.
Transient programmed
with output relay open.
Operation not possible
with external clock
Too much data received.
AC input line related error.
Harmonic contents of user
defined wave shape is too
high and could damage
amplifier output stage.
An amplifier failure. Can
be reported at any time.
Over voltage detected on
output
Remedy
influence (Load, voltage kickback, etc.)
Load exceeds current limit a
Constant Voltage (CV) mode of
operation. Reduce load or increase CL
setting
Reduce load. Ensure proper airflow and
exhaust clearance. Check fan(s) for
operation.
External sync signal missing,
disconnected or out of range.
Save power on settings again to
overwrite old content.
Contact CI service department at
support@calinst.com
to obtain
instructions on restoring configuration
data.
Recycle power.
Contact CI service department at
support@calinst.com
to obtain
instructions on restoring calibration data
or recalibrate unit.
Check programmed lists.
This error may occur when selecting user
defined wave shapes with higher crest
factors. Reduce programmed RMS
value.
Check dwell times in transient list
settings. Increase dwell time or change
slew rate for affected parameter.
Wait till transient execution is completed
or abort transient execution first.
Close relay before attempting transient
operation.
Switch to internal sync. (Default)
Break up data in smaller blocks.
Possibly due to low line input condition
requiring too much input current.
Reduce harmonic content or reduce
fundamental frequency programmed.
Determine which amplifier is at fault with
self-test or checking amber LED's on
amplifier control board. Replace
amplifier.
Check output voltage for correct RMS
value.
