8 POWER 1. STEP
Range for entering the stage outputs can be increased here (e.g. HV-measuring)
9 CONTROL [3] PHASE
The measuring system of the controller is generally based on single-phase
measurement. For all standard settings (three-phase), the measurement is
converted and all outputs displayed as three-phase values (symmetry in grid
assumed). In the single-phase setting, display and control apply only to the single-
phase value measured.
10 DISPLAY
Changeover between cos/tan Phi for all displays and calculations in the device
11 HARMONICS
Release of calculation and display of harmonics.
8.2. Expert mode 2
The additional 2nd expert mode includes all messages for operation, warning and error which
are displayed by the Prophi-6T. Here they may be deactivated separately. When deactivated,
the indication of the message in the display as well as possible activation of the relay or effects
on the control behavior are suppressed.
EXPERT MODE 2
Activation of particular operation, warning and error messages (list of all
messages in menu plan last page)
2 ALARM TIME
3 UNDERVOLTAGE
4 OVERVOLTAGE
5 FREQUENCY
Measurement by the controller is done automatically in grids of 40 ... 80 Hz.
In grids with extremely poor voltage quality it is recommend to select a fix frequency (50
or 60 Hz) to avoid measuring errors due to voltage sags.
