Test Support – HMI Data Access Menu Path

Function

Measurements ► Analog primary values ►TRM40 ►

Displays all analog voltages and currents in primary values

Measurements ► Analog secondary values ► TRM40 ►

Displays all analog voltages and currents in secondary values

Test ► IED test mode ►

Places the relay in the test mode by blocking all trip functions and sets the amber Start LED to flashing. This is used in conjunction with menu selection ‘Function test modes’.

Test ► Function test modes Allows selection of functions to enable while in the ‘IED IED ►►► test mode’. This is done to test functions individually. You must be sure to enable the function to be tested and all functions that supervise (enable) it. E.g. ZMH1 (zone-1) requires enabling of PHM (phase selection and load encroachment).
