Example of the analogue channel 4 display. Here the external reference
value specification for peak load operation. The text can be entered with
ParaWin.

+ 3400 mV
SPEED CONTROLLER
The example of the display of analogue output channel 5. Here the signal
to the speed controller. The text can be entered with ParaWin.
25
+ 1205 mV
COS PHI CONTROLLER
In the example of the display of analogue output channel 6. Here the signal
to the cos φ controller. The text can be entered with ParaWin.
Display 13, synchroscope
If the synchronisation is not selected, the synchroscope lettering appears instead of the symbols. If the system to be con-
nected is too fast, the indicator runs in a clockwise direction; if it is too slow, it runs anti-clockwise. This display is analogue
to the display of an indicator synchroscope.
Display 18, runtime until the next maintenance
The operating hours counter until the next maintenance is decremented from a maximum value. If the counter reading
reaches 000000, an alarm is triggered (if parametrised). A grace period during which the maintenance must be carried out
can be parametrised. The runtime counter until the maintenance now shows negative operating hours. If no maintenance
has been carried out even after the grace period has expired, another alarm can be activated.
If the grace period is set to 000000, the counter does run into the negative range. It can be set on the display. Thus, the
Maintenance interval reached alarm is deleted.
If a grace period of > 0 is entered (e.g. during the guarantee period), the counter can only be set by the supplier and only
with ParaWin. Therefore, the Maintenance interval and Maintenance interval exceeded alarms can only be deleted by
authorised persons.
Display 19, daily runtime
Here, the operating hours are counted up to 999 hours and 59 minutes. It is used for recording short runtimes (e.g. during
trial operations or mains failures). It can be set to 00:00 without the main operating hours counter being changed.

Further functions
15.1.
Frequency controller in standalone operation
The automatic system issues commands for the speed controller if the function is enabled if the frequency is not
within the parametrised window. A break is taken between two commands in order for the motor to have time to
carry out the order.
15.2.
Voltage controller in standalone operation
The automatic system issues commands for the generator voltage controller if the function is enabled and if the
voltage is not within the parametrised window. A break is taken between two commands in order for the genera-
tor voltage control to settle.
