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 LED Limit 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 FAULT LED, and via the fault relay K1. The fault log may be
read via the Thyro-Touch display, or via the Thyro-Tool Pro PC software interface
after selecting the status line. Simultaneously with the fault signal, you can use the
Pulse Lock On/Off (with acknowledgement), Pulse Lock On/Off (without
acknowledgement), or Regulator Lock On/Off (without acknowledgement)
configuration to require that pulse shutdown occur. The number and content of
