change.

6.4 LIMITATIONS

In addition to the configured control mode the following variables can
be limited:
• voltage limitation (U)
• current limitation (I)
• power limitation (P)

TAB. 3 EFFECTIVE LIMITATIONS
Besides this the Thyro-AX 1A/3A ...H RLP2 is equipped with a peak
current limitation (î = 3 x I ) in phase angle.

6.5 PULSE INHIBITION

The pulse inhibition (terminals X2.1 – X2.2) is activated by opening
the pulse inhibition bridge, which means that current no longer flows.
When the pulse inhibition is activated the touch display turns red and
in the data logger "Pulse on" is listed. After switching on or after pulse
inhibition the first Takt pulse (in TAKT operation) runs through with
the soft start function. This is important for transformer load if it was
switched off in an undefined way (remanence). In the case of the
Thyro-AX 2A or Thyro-AX 3A the pulse inhibition is only wired to the
master (L1, left).

6.6 CURRENT AND VOLTAGE TRANSFORMER

The power controller has a current and voltage transformer on the load
side per power unit which is internally wired. In addition each controller
also has an external current and voltage transformer terminal which
can be used via internal link plugs as an alternative to the internally
built-in parts. This can increase the measurement accuracy in the case
of very small voltages. For details on how to convert over please use
the contact information indicated in chapter 4.
External current and/or voltage transformer are to be connected in-
phase, see connection diagram:
