Description
75° el is set per default.
If "α start" is set to "No" in the configuration, this window is
not displayed and α start is set to 0° el.
Current limiting:
It is possible to modify the current limit value in phase-
angle operation mode during operation.
This window is not displayed if "Current limiting" is set to
"No" in the configuration.
Resistance limitation:
Indirect temperature limit for a heating element with a
positive temperature coefficient.
Description
In logic operation, the phase angle of each sine wave can
be varied.
This means that excessive electrical impact stresses on
the load can be prevented.
In the case of continuous thyristor control via the analog
input, the maximum actuating variable at the measuring
range end (e.g. 20 mA) can be varied during operation.
The displayed value depends on the "Subordinate control
loop" setting:
