CONFIGURATION OF THE METER
PARAMETERS
During normal operation (
Measurement
) the unit displays and signals the values that
characterize the state and the course of the generator synchronization process. The NS5
meter performs voltage measurement functions (voltage difference), frequency (frequency
difference), and phase shift between the voltage signals of the network and the generator.
The meter menu is divided into the following groups:
Parameters
– configuration of parameters of the meter,
Relays
– configuration of SYNC and AL relays,
Ethernet
– configuration of Ethernet interface parameters,
Modbus
– configuration of RS485 interface parameters,
Settings
- settings: password, language, brightness level,
Information
– preview of program version, serial no., MAC address,
To enter the parameter menu, press the button
for about 3 seconds.
Use the buttons
