4.2.3 Setpoint value configuration
Current load current
10 % to max. load
current for the de-
vice type +10 % Current limiting:
It is possible to modify the current limit value in phase angle
control mode during operation.
The current is limited in the master branch.
This window is not displayed if "Current limiting" is set to "no"
in the configuration.
Current resistance
0 to 999.99
Ω
Resistance limitation:
Indirect temperature limit for a heating element with positive
temperature coefficients.
The resistance value is measured in the master branch.
Resistance cannot be measured directly in the three-phase
current economy circuit. However, the current resistance mea-
sured at an operating point can be used as a resistance limit
value.

In the case of continuous SCR control via the analog input,
the maximum actuating variable at the measuring range end
(e.g. 20 mA) can be varied during operation.
The measured values in the master branch are measured.
The displayed value depends on the "Subordinate control
loop" setting:

P: display in kW (example: 0 to 8.00 to 9.20 kW)
I

and I: display in A (example: 0 to 20 A)
None: display in % (example: 0 to 100 %)

In the case of continuous SCR control via the analog input,
the base load at the measuring range start (e.g. 0 mA) can
be varied during operation.
The measured values in the master branch are measured.
The displayed value depends on the "Subordinate control
loop" setting.
