5 Configuration
Cycle time
Fixed (500 ms)
(For slow heating ele-
ments)
Note:
This setting is only available in burst-firing operation 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)
The cycle time is variable with this setting. At the required out-
put level, the device attempts to find the shortest possible cy-
cle time for full sine waves. At an output level of 20 %, this re-
lates 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 three full sine waves are always let through.
At an output level of 50 % and with the 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
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
controller after power ON and is deactivated per default.
Yes
"Yes" means that a soft start with phase-angle control or pulse
groups is performed after power ON.
