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
= 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“)
Note : the U/I/R operation mode can only be used after it has
been unlocked in the

Options menu. The unlock code can
be purchased at the company where the power supply has also
been purchased. The serial number of the unit is required to
be told when purchasing the option, because the unlock code
is related to it.
In U/I/R operation mode you can add an adjustable internal
resistance to this voltage source.
The voltage set value is related to the off-load voltage U
o
of the
power supply. The off-load voltage is reduced by the product of
I
act

Ri
set
. The resulting voltage is calculated as follows:
U
soll
= (U
0
- I
ist
• Ri)

Isoll, Psoll
Clarification:

CR This is shown in the display while the internal resi-
-stance control is active and U/I/R operation is set.
The internal resistance Ri
set
is displayed instead of the power
P
set
while U/I/R mode is active. However, the actual value of
the power is still displayed.
Reactivation after an overtemperature error

Output on OT
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
overtemperature shutdown limit. The error

OT (overtemperature) is then displayed
as a warning.
= ON The power supply output remains on and will
provide voltage as long as at least one of the
power stages keeps working.
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: restore
= 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.
No.

* Resistance values (red) only with unlocked option U/I/R.
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.
