8.2.5 Step 4, readjustment of controller settings

It can be necessary to make a readjustment of the controller settings, if during testing the genset turns out to
be unstable to some extent. If this is the case, then adjust the K
The Ti and Td settings are only available when analogue controller output is used.
To see the effect of the new adjustments when tuning in the Multi-line 2, remember to make a
regulation deviation, e.g. by applying a load jump.

8.2.6 Manual governor and AVR control

In many cases, it is difficult to tune in the controller using load jumps (no load bank available). When this is
the situation, the manual control can be used as an easy way to make regulation deviations during the com-
missioning.
This function can be activated by pressing
AOP buttons for governor or AVR control in semi-auto mode. The intention of this function is to give the com-
missioning engineer a helpful tool for adjustment of the regulation.
The function of the regulation window depends on the selected mode:
G 0

f-U Setp

8.2.7 Manual mode/switchboard control

In manual mode or switchboard control, the regulation is deactivated. When activating the up or down arrows,
the output value to GOV or AVR is changed, this is the Reg. value in the display. The up and down arrows
have the same function as the digital inputs or AOP buttons for governor and AVR control when the window is
open. To exit the regulation window, press "back".
