NORMAL OPERATION

Each time you turn the unit on, the unit runs a self-diagnostics procedure to ensure
that it is performing correctly. Follow the procedures in this user manual for first time
operation the first time you operate your unit. Consult the troubleshooting section if
you have issues or problems operating your unit after you have followed the first
time operation guidelines.
You can monitor your unit with a system (user-supplied) controller or a Windows-
based personal computer running Thyro-Tool Pro software. To order this software,
contact your AE sales representative.

OPERATING MODES

Full-Wave Switch (TAKT)

In full-switch mode, whole multiples of the mains periods are always switched and
harmonics are minimized.
The mains are switched on/off depending on the prescribed time period.
Ts = switch-on time
Figure 5‑40. TAKT waveform
The start and stop ramp functions can be used in TAKT mode. Ramps are used with
the operation of large single loads to reduce pulse-shaped mains loads and therefore
to reduce voltage variations. The ramps are implemented by applying periods with
phase-angle firing, using the parameters SST and SDN (see the following figure).
