5. RELAY SETTINGS
5.1 Relay settings
All the settings can be entered into the relay via the front keypad or using a PC with a K-
Bus connection. The selection can be made in the menu columns for settings, but
password might be required before some settings can be entered. Two setting groups
are available to allow the user to set Group 1 to normal operating conditions while Group
2 can be set to cover abnormal operating conditions.
The quantities that require setting are listed below with the adjustment range and step
sizes:
