Controller Response
If the load resistance changes (for example, due to temperature effect, aging, or load
fault), the power controller responds as shown in the following table.

If one of the limits is exceeded, then the limit relay K2 and the Limit LED react (default values of
parameter settings).
MONITORING
Faults occurring in the power controller or in the load circuit are signaled. Signaling
is performed via the LED indicators, and via the fault relay K1. The fault log can be
read via the Thyro‑Touch display, or via the Thyro-Tool Pro software interface after
