Operating Instructions ACU
Via parameter Technology Controller Release 58 , you can stop the technology controller. The
current P and D portions are kept at the last value before shutdown. The output value and the I
portion will be deleted when Technology Controller Release 58 is turned off.
Note the default link of parameter Start Clockwise 68 to the logic signal of the
technology controller:
Start Clockwise 68 = "13 – Technology Controller Start".
This link must not be changed. The technology controller becomes active with the
controller release at digital input S1IND/STOA.

The function selected via the parameter Operation Mode 440 defines the behavior of the
technology controller.
The technology controller is switched off, the reference value
specification is done via the reference percentage channel.
