The RC for the XT7 is active only when the rating plug is present. All of the Synchrocheck functions are for signaling. An adjustable pre-alarm threshold (50...90%) is available for L protection, as well as a fixed pre-alarm threshold is available for G and Gext protection. (1) With Vaux all thresholds are available. Without Vaux there are minimum threshold limitations. Details available on the "User manual for use and maintenance of Ekip Touch Trip units" (2) Available for XT7 only.
