► How to load a function
1.
After setting the values for the required signal generation, tap on the
touch area .
The device will then load the data into the internal controller and changes the
display. Shortly afterwards the static values are set (power and voltage or
current), the DC input is switched on and the touch area
Only then can the function be started.
Because the DC input is automatically switched on in order to settle the start situation, the static
values are effective to the source immediately after loading the function. These static values
represent the situation before start and after the end of the function, so it doesn't need to start
from 0. Only exception: when applying any function to the current (I), there is no adjustable
static current value, so the function would always start from 0 A.
► How to start and stop a function
1.
The function can be started either by tapping
currently switched off. The function then starts immediately. In case START is used while the DC input is
still switched off, the DC input will be switched on automatically.
2.
The function can be stopped either by tapping
behaviour:
a) The
b) The "On/Off" button stops the function and switches the DC input off.
Any device alarm (overvoltage, overtemperature etc.), protection (OPP, OCP) or event with
action = Alarm stops the function progress automatically, switches off the DC input and reports
the alarm.

are only stops the function, the DC input remains ON with the static value in effect.
Description
A = Amplitude of the signal to be generated
Offs = Offset, based on the zero point of the mathematic sine
curve, may not be smaller than the amplitude.
Static frequency of the signal to be generated
Application and result:
A normal sine wave signal is generated and applied to the selected
set value, e.g. current (I). At a constant input voltage the current
input of the load will follow a sine wave.
For calculating the maximum power input the amplitude and offset
values for the current must be added.
Example: with an input voltage of 15 V and sin(I) selected, set the
amplitude to 25 A and the offset to 30 A. The resulting maximum
input power is then achieved at the highest point of the sine wave
and is (30 A + 25 A) * 15 V = 825 W.
