                                    Some LED signals indicate connection errors or operational errors that require corrective or maintenance
                                    operations. The following are the suggestions for checking with reference to the preceding LED table:

                                     note
                                     A        Contact ABB and give details about the state of the LEDs on the unit.
                                              Check the connections between trip unit and accessories (Rating Plug, trip coil, sensors,

                                              etc).
                                     C        Normal operation/signalling provided by the trip unit.
                                              Error in setting of the dip-switches. Check and correct the following conditions:
                                               • All the dip-switches of L are in the ON position
                                               • I1 ≥ I2 or I2 ≥ I3.
                                               • Iu < (2 * In * I1) in the case where InN = 200 %.
                                     D         • I4 < 0.3 In (con In = 100 A), 0.25 In (con In = 400 A) or 0.2 In (for all other sizes), in the
                                              absence of auxiliary power supply.
                                               • t2 > 0.4s (in the case of UL circuit-breaker)
                                               • t4 > 0.4s (in the case of UL circuit-breaker)
                                               • I4 > 1200 A (in case of UL circuit-breaker)
                                     E        Install by pressing and holding the itest pushbutton for at least 5s.
                                     F        Connect via Ekip Connect in order to set the Local Bus or to confirm maintenance.
                                     G        Replace the battery.
