5 Configuration
50 2011-07-01/00561073 [SCR Power Controller TYA202]
Cycle time Fixed (500ms)
(for slow heating ele-
ments)
This setting is only available in burst-firing mode.
For a fixed period of 500ms, for example, at an output level of
20% 5 sine waves are switched on and 20 are switched off.
Fastest possible
(for heating elements
that respond quickly)
The cycle time is variable for this setting. The device tries to
find the shortest possible cycle time for whole sine wave cy-
cles. For an output level of 20%, this means one sine wave ON
and four sine waves OFF.
Min. duty cycle None
3 full sine waves
(for controlling trans-
former loads)
Dependent upon the setting for cycle time.
At least 3 full sine waves are always let through.
At an output level of 50%, for example, 3 sine waves are
switched on and off at the fastest cycle time possible.
a start no This setting is only available in burst-firing mode.
If "Yes" is set, the first half-wave of each pulse group is cut
back with the set phase angle a.
yes
Angle a start 0 ... 70 ...90°el Phase angle for a start
Soft start no This setting determines the starting behavior of the power
controller after power ON. The factory setting is "off".
yes "yes" means that a soft start with phase angle control or pulse
groups is executed after mains ON.
