3.3 Voltage control

3.2.2

Controlling remotely operated transfer switching equipment

The control of remotely operated transfer switching equipment (single motor operator) is
similar to the control of circuit breakers with motor operator, however it requires only three
outputs (close Line 1, open both lines, close Line 2) and two inputs for the status of the
transfer switching equipment.
● The command mode (continuous signal or pulse) can be selected by setting the
appropriate parameter under P05.07 in menu P05 to "Chg. Pul." or "Chg. Con."
Precise circuit diagrams as well as the parameters to be set can be found in chapter
Connection (Page 65) or in chapter Parameterization (Page 115).
3.2.3

Controlling contactors

If two contactors are used, two outputs (CL.1 and CL.2) and two status inputs are required.
● In this case the appropriate parameter under P05.07 in menu P05 must be set to
"Contactors" in the command mode.
Precise circuit diagrams as well as the parameters to be set can be found in chapter
Connection (Page 65) or in chapter Parameterization (Page 115).
3.3 Voltage control
This section illustrates how a voltage measurement is achieved for the ATC6300.
Note
Procedure for voltage measurement
The fundamentals of the procedure for adjusting the voltage measurement are explained
below.
The exact parameters can be found in chapter Parameterization (Page 115).
All parameters and settings can be adjusted by the user in the menus P02 (General), P05
(Changeover), P06 (Parameter Line 1) and P07 (Parameter Line 2).
● The general system settings can be adjusted in Menu P02, including the rated voltage
and frequency. These are used as a reference for setting the percentage thresholds.
● A voltage ratio (VT) can be set if a voltage is applied to the measurement inputs of the
device which is higher or lower that the set rated voltage. In this case the display and
setting of limit thresholds are also performed on the actual variables in relation to the
system.
● The device can be adjusted for the voltage measurement of three-phase networks with or
without neutral conductor, two-phase or single-phase networks (P02.06).
