V1.00/EN/00709725 [Thyristor power controller TYA S202] 55
5 Configuration
Cycle time Fixed (500 ms)
(For slow heating el-
ements)
Note:
This setting is only available in burst-firing operation.
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)
The cycle time is variable with this setting. At the required out-
put level, the device attempts to find the shortest possible cycle
time for full sine waves. For an output level of 20 %, this means
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 three full sine waves are always let through.
For example, at an output level of 50 % and the fastest possible
cycle time, three sine waves are switched on and three
switched off.
Note:
Particularly suitable for the control of transformer loads
α
start No Note:
This setting is available in continuous burst-firing operation
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
.
Yes
α
start angle 0 to 75 to 90° el Phase control angle for

start
Soft start No This setting determines the starting behavior of the power con-
troller after power ON and is deactivated by default
Yes "Yes" means that a soft start with phase-angle control or burst-
firing is performed after power ON.
