III- Introduction TeSysT is the new multifunction protection Controller which replace the old multifunction protection relay LT6. The aim of this document is to help you in the conversion from LT6 to TeSysT through: - Wiring differences - Protection/Control/Monitoring function differences - Mapping equivalence

Be careful : LV1-LV2-LV3 are connection to measure voltage three phase. Contrary to LT6 you do not need a transformer to measure voltage For Logic Inputs of LTMR***** : A2 supplies in internal COM (-) (use 24Vdc or 100-240 Vac provided by connection “C” to switch on logic inputs or thanks to the same power supply connected on A1) For Logic Inputs of LTMEV** : COM (-) is provided by an external power supply.

V- Limitation
This document makes a comparaison between LT6 and TesysT. Be careful, you can only make an equivalence if you have a TesysT Modbus (reference : LTMR**M**). We advise to use a LTMEV** with the controller LTMR**M**. This configuration gets all functions of protections available with TesysT product.
