Other control elements

6.3.1 Rotary knobs

Both of the rotary knobs have a push button function. Pushing
any or both of these will effect following:
a) Fine adjustment mode (Fine)
A short push of any of both buttons activates or deactivates the
fine adjustment mode for manual operation. If „Fine" is active,
all set values, thresholds and limits can be adjusted in smallest
possible steps, no matter what mode is currently active (preset,
memory ect.). It is indicated by the status text „Fine" in the
status area. Also see section „6.4 Adjusting set values" below.
b) Device setup
Pushing both buttons together for >3s while the output is off
changes to device setup. It is left the same way.
6.4

Adjusting set values

1. In manual operation
During manual operation, both rotary knobs are used to conti-
nuously adjust the set values of voltage and current from 0%
to 100% nominal value in predefined steps (see table). In order
to set the values for OVP and UVL the button Preset UVL/
OVP has to pushed once or twice. In order to set the power
set value (models from 1kW only) the button Preset Power
has to be pushed.
Note
The OVP value can be lower than the voltage set value and
will cause an OV error as soon as the output is switched on
and the actual voltage reaches the OVP threshold!
Setting values manually can be done in fine or coarse steps,
whereas coarse is default. Fine is required to be activated by
the one of rotary knob pushbuttons and has a step width of 1.
For coarse adjustment, following step widths apply in depen-
dency of the nominal values (also refer to technical specs):
Voltage / OVP / UVL
Nom. val. Coarse Fine
16V 0.1V 0.01V
32V 0.2V 0.01V
65V 0.5V 0.01V
80V 0.5V 0.01V
160V 1V 0.1V
360V 2V 0.1V
Power
Nominal value Coarse
1000W 0.01kW
1500W 0.01kW
Note
The resolution of the set value adjustment in some cases is,
depending on the nominal values, higher than the one of the
output voltage. Thus it can happen that the output voltage
only changes every 2 or 3 steps.
