Response after Power ON with Varying Line Voltage
Ranges (230 V
115 V)
Up to and including Firmware Version 004
After „Power ON“, a distinction is made - on the basis of the line
voltage detected - between the two available power ranges.
When the line voltage is „low“, output power Pnom is reduced by
half (see chapter 4.1).
The specified value „PSET < Pnom“ (and/or „PSET < Pnenn/2“ in
the case of power derating), in turn, is the setting criterion for the
function „Power control“. After an automatic change of Pnom it
may be necessary to correct the PSET value for power control!
Power ON & Setting „Power_ON RST / SBY / RCL / ...“:
•
„RST“
Pnom is always readjusted in accordance
with the detected line voltage.
•
„SBY“, „RCL“
A low line voltage always leads to a reduced
Pnom value. If the device is subsequently
switched on to a „high“ line voltage, the low
Pnom value remains active until either:
– a „RESET“ is performed (!)
or
– „Power“ is reconnected with parameter
setting „POWER_ON RST“.
Changes between the line voltage ranges result in system mess-
sages, see Err AC-L and Err AC-H in chapter 11.
As from Firmware-Version 005
After „Power ON“, a distinction is made - on the basis of the line
voltage detected - between the two available power ranges.
When the line voltage is „low“, output power is limited to approxi-
mately 55 % of the nominal power.
If the device is switched on in setting „POWER_ON RST“ at „low“
line voltage, the setting limit value is reduced to half the nominal
power for parameter PSET.
The specified value „PSET < Pnom“ (and/or „PSET < Pnenn/2“ in
the case of power derating), in turn, is the setting criterion for the
function „Power control“.
Power ON & Setting „Power_ON RST / SBY / RCL / ...“:
•
„RST“
Pnom is always readjusted in accordance
with the detected line voltage.
•
„SBY“, „RCL“
A low line voltage always leads to a reduced
maximum output power. The setting limit
values for parameter PSET, however, remain
unchanged until either:
– a memory recall of a corresponding device
setting is performed
or
– „Power“ is reconnected with parameter
setting „POWER_ON RST“.
Changes between the line voltage ranges result in system mess-
sages, see Err AC-L and Err AC-H in chapter 11.
