Then the results are...
Off Off • Disturbances are not stored.
• LED information is not displayed on the HMI and not stored.
• No disturbance summary is scrolled on the HMI.
Off On • Disturbances are not stored.
• LED information (yellow - start, red - trip) are displayed on the local
HMI but not stored in the terminal.
• Disturbance summary is scrolled automatically on the local HMI for the
two latest recorded disturbances, until cleared.
• The information is not stored in the terminal.
On On or Off • The disturbance report works as in normal mode.
• Disturbances are stored. Data can be read from the local HMI, a
front-connected PC, or SMS.- LED information (yellow - start, red - trip)

• The disturbance summary is scrolled automatically on the local HMI for
the two latest recorded disturbances, until cleared.
• All disturbance data that is stored during test mode remains in the ter-
minal when changing back to normal mode.
