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 Test ► Function test modes

►►►

Allows selection of functions to enable while in the 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).
