Err
PFC
PFC Error
Inadequate/unstable line voltage or device error, not ready for operation, device controls
disabled, shutdown (OUTPUT OFF)
Err
AC-H
Change from AC-LOW to AC-HIGH
Transition from the „lower“ line voltage range (= status after power ON) AC_L to the „upper“
range AC_H generates message „ERR AC-H“.
Please note: Pnom value is not automatically raised in the process! A
new „Power ON“
is re-
quired for this purpose, including:
– automatic RESET (parameter setting: „POWER_ON RST“) or
– subsequent „RESET“ (manual operation/interface) or
– Recall of a suitable SETUP memory
(which has not been saved under power derating conditions!)
(Pnom is the reference quantity for the PSET function!)
Err
AC-L
Change from AC-HIGH to AC-LOW
up to and including firmware 004:
Transition from the „upper“ line voltage range to the „lower“ range generates message
„ERR AC-L“ and
results in a shutdown
if no power derating has been active (operation dis-
abled, „Power ON“ required!)
Transition from the „upper“ line voltage range AC_H to the „lower“ range AC_L
generates message „ERR AC-L“
without shutdown
if power derating has already been active.
as from firmware 005:
Transition from the „upper“ line voltage range to the „lower“ range generates the message
„ERR AC-L“ and results in power derating,
as long as the status „AC LOW“ „lower“ line voltage range applies. Upon reversal of the line
voltage to the „upper“ line voltage range (status „AC HIGH“), the power derating is cancelled.
Err
AC-F
AC-FAIL
Inadequate/unstable line voltage or device error, not ready for operation, device controls
disabled, shutdown (OUTPUT OFF)
as from firmware 010:
Temporary deactivation for the purpose of device protection.
If insufficient/instable line voltage is present or a device error occurs, the instrument shuts
down (OUTPUT OFF) and is not ready for operation during this time.
After approximately 0.25 s, an automatic restart is performed by the instrument in accordance
with the settings for POWER_ON (standby, reset, recall).
