Cause
Internal error
M essage queue full.
Unable to complete query.
Query issued but response not
read.
Query incomplete.
Query cannot be completed
Query incomplete.
Output voltage does not match
programmed value.
Current limit exceeded.
Temperature of heat sink too
high.
Could not sync to external sync
signal.
Power on settings could not be
recalled.
Hardware configuration settings
lost.
M emory corrupted.
Calibration data lost.

Too many messages. Read status
using SY ST:ERR query until 0, "No
Error" is received indicating queue

flow. Response must be read after
each query to avoid this error.
Check for terminator after query
command.
Check application program for
multiple queries
Check for terminator after query
command.
Load exceeds current limit and unit is
in Constant V oltage (CV ) mode of
operation. Reduce load or increase CL
setting.
Output voltage is driven above
programmed voltage by external
influence (Load, voltage kickback,
etc.)
Load exceeds current limit and unit is
in Constant V oltage (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 service department at

obtain instructions on restoring
configuration data.
Recycle power.
Contact service department at
service@programmablepower.com
obtain instructions on restoring
calibration data or recalibrate unit.
Start phase angles can only
programmed at the start of a
transient list. Once a transient is in
progress, phase angle cannot be
changed.
Switch to A C or A C+DC mode.
