Number Message String Cause Remedy
6 “Limit memory lost” Hardware configuration
settings lost
Contact AMETEK Service Department
to obtain instructions on restoring
configuration data.
7 “System memory lost” Memory corrupted
Recycle power. Contact AMETEK
Service Department for instructions if
memory remains corrupted.
8 “Calibration memory lost” Calibration data lost Contact AMETEK Service Department
to obtain instructions on restoring
calibration data or recalibrate the unit.
9
“Start angle must be the first
sequence”
Start phase angle in the
wrong place
Start phase angles can only be
programmed at the start of a transient
list. Once a transient is in progress, the
phase angle cannot be changed.
10 “Illegal for DC” Operation is not possible in
DC-Mode
Switch to AC or AC+DC mode.
13 “Missing list parameter” One or more transient list
parameters missing
Check programmed lists.
14 “Voltage peak error “ Peak voltage exceeded This error could occur when selecting
user-defined wave shapes with higher
crest factors. Reduce programmed
RMS value.
16 “Illegal during transient” The operation requested is
not available while the
transient is running
Wait until transient execution is
completed or abort transient execution
first.
17 “Output relay must be
closed”
Operation is not possible
with an open relay
Close relay before attempting
operation: e.g., transient execution
requires the output relay to be closed.
18 “Trans. Duration less than
0.5 msec”
Dwell time below the
minimum of 0.5 ms
Increase dwell time to at least 0.5 ms.
19 “Clock and sync must be
internal”
Operation is not possible
with an external clock
Switch to internal sync (default).
20 “Input buffer full” Too much data received Break up data into smaller blocks.
21 “Timeout error”
Controller did not receive a
command from the display
Reduce remote command activity.
Internal communication between the
controller and display has been
impacted.
22 “Waveform harmonics limit”
The harmonic content of
user-defined wave shape is
too high for amplifier
capability
Reduce harmonic content or reduce the
programmed fundamental frequency.
24 “Output relay must be open”
Attempting to change
settings that expect the
relay to be closed
Ensure that the output relay is open
when changing settings such as range,
sense, and AC/DC/AC+DC mode.
25 “Overvoltage Protection Trip” Overvoltage limit exceeded Ensure that OVP is programmed
sufficiently above the output voltage
value. Check for load inductive
kickbacks or overshoot on output.
Ensure that remote sense leads are
connected if utilized.
29 “DC component exceeds
limit”
Waveform selected
contains a DC component
Select AC+DC mode.
