5 Configuration
52 2012-12-31/00561073 [SCR power switch TYA202]
Cycle time Fixed (500 ms)
(For slow heating ele-
ments)
Note:
This setting is only available in burst firing mode.
For example, for a fixed period of 500 ms, 5 sine waves are
switched on and 20 switched off at an output level of 20 %.
Fastest possible
(For quick-response
heating elements)
With this setting, the cycle time is variable. At the required out-
put level, the device attempts to find the shortest possible cy-
cle time for entire sine wave cycles. At an output level of 20 %,
this relates to one sine wave ON and four sine waves OFF.
Min. ON period None
3 full sine waves
Dependent on the cycle time setting.
At least 3 full sine waves are always let through.
For example, at an output level of 50 % and fastest possible
cycle time, 3 sine waves are switched on and 3 switched off.
Note:
Particularly suitable for the control of transformer loads
α
start No Note:
This setting is available in continuous burst-firing mode and in
logic operation.
No: for resistive load
Yes: for transformer loads
If set to "Yes", the first half-wave of each pulse group is cut
with the set phase control angle
α
.

start
Soft start No This setting determines the starting behavior of the power
controller after power ON and is deactivated ex works.
Yes "Yes" means that a soft start with phase angle control or pulse
groups is performed after power ON.
