5.1 Introduction
The NZM-XMC-DISP display unit is used to display the electrical variables
measured by the basic devices. The data is transferred via an RS485
interface. Display has the function of masters in the communication and
consequently, periodically, it interrogates to the measuring device to read the
electrical parameters that are needed.
5.2 Surface mounting
The display shows the measured and calculated values in four lines.
The values of the cables L1, L2 and L3 are shown together.
The bottommost line will show the calculated value.
The display is provided with four pushbutton actuators at the bottom edge.
•
“Reset” pushbutton clears the display.
•
Arrow pushbutton actuator switches to the next value.
•
“max” pushbutton shows the maximum values.
•
“min” pushbutton shows the minimum values.
5.3 Order of displays
The following graphics show examples of values in the order how they are
shown on the display by scrolling with the arrow pushbutton actuator.
Figure 19: Order of displays (example)
•
The first (i.e. left) display shows the voltage (measured in V = Volt).
Pressing the arrow pushbutton actuator activates the next display:
•
The measured currents are shown (measured in A = Amps).
•
Pressing the pushbutton actuator again then causes the active power
(measured in kW = Kilowatts) to be shown in the third display from left.
•
Pressing the pushbutton actuator again causes the display of the
reactive power (measured in kvar).
