Using the power supply
7.1 Defining operation parameters
Setup operation mode +
The way of adjusting the set values, which operation mode is
used, how the unit shall react after the mains has restored or
the behaviour of the unit after an overtemperature error can be
configured here.
U/I/P or U/I/R operation mode
Setup op. mode
Default:
U/I/P
= U/I/P
The power stage is controlled by voltage, current
and power set values (only models from 1kW and
with power regulation)
= U/I
The power stage is controlled by voltage and
current (models up to 640W)
= U/I/R
The power stage is controlled by voltage,current
and resistance set values and a settable, but not
adjustable power set value (only with unlocked
option „internal resistance control“). The U/I/R
operation mode can only be used after it has been
unlocked in the
Options
menu.
Reactivation after an overtemperature error
OT disappear
Default:
auto ON
=OFF
The power supply output remains switched
off, even if the unit has already cooled down.
The error
OT
(overtemperature)
is displayed as an alarm.
= auto ON
The power supply is automatically switched on
after the unit has cooled down below the over-
temperature shutdown limit. The error...
OT
(overtemperature) is then displayed as a warning.
Warnings as well as alarms are only deleted from the display
after they have been acknowledged (see also „6.13 Alarms,
warnings and signals“).
Output state after „power on“
Power ON
Default:
OFF
= OFF
The power supply output remains switched off
after the mains voltage returns or after the unit
was switched on.
= restore
The power supply output is set to the state it
had before a mains voltage loss occured or
before the unit was switched off. In case it was
ON when the unit was switched off, it will also
be ON when the unit is switched on again.
7.2 Predefining preset lists
Preset List +
You can predefine up to four different presets.

Resistance values (red) only at unlocked option U/I/R.
Power values (green) only with models from 1kW
With the parameter
Accept set value =
from preset list
you can switch from the normal set values (eg. adjusted by the
rotary knob) to one of the predefined sets or switch between
predefined sets. You can actually „jump“ between set values
with this option.
7.3 Adjustment limits
Note
All the below described limits only affect the normal set values
and not set values that can be edited for sequences in the
function manager
Adjust
The maximum and minimum adjustment limits can be defined
here. These limits are always interfering, in local or remote
mode, i.e. unit is controlled by a PC.
Limits of the set value of voltage
U adj
Default:
0V, U
nom
=
{U
adj.min
} {U
adj.max
}
Whereas U
adj.min
= {0...U
adj.max
} and U
adj.max
= {U
adj.min
...U
nenn
}
You can define the lower and upper limit of the adjustable volta-
ge here. Set values which exceed these limits are not accepted,
neither from the control panel nor from the remote control via a
PC (communication with interface cards).
