V1.04/EN/00561071 [Thyristor Power Switch TYA 201]
This setting determines which input specifies the setpoint value, how high the base
load is, and which alternative value should be applied in the event of an error.

This setting is only available if Power controller
selected.
This setting specifies which signal the α input should control or whether it should be
fixed.
The "α input" value is a phase angle with which all sine waves are cut to limit the
power.
Not to be confused with the value for α start!

Description
This setting specifies which analog input supplies the setpoint
value for the power output.
Note:
These inputs can also be used for logic operation.
v For switching level, see Chapter 10.7 "General speci-
fications"
Means that the setpoint value for the power output is provided
via an interface.
Note:
This setting is only available if Power controller
r
control Logic (switch) is selected.
In this case, the power controller is controlled in the same way
as a solid-state relay (SSR) via digital input 1 or 2:
r
contact: closed 100 % and open
(for control direction default setting).
No phase angle is specified (full sine waves)
This standard signal specifies the phase angle as shown in
the diagram.
Phase angle α
The phase angle is entered as "α input value".
The phase angle is specified via an interface.
This is the phase angle if "Value, adjustable" has been select-
ed under α input.
