It comprises a 7-inch color screen with capacitive touch sensing anda Home button at the bottom of the LHMI.The LHMI must be paired with the protection relay to enable all thefunctionalities in it. See the operation manual for the pairingprocedure.The LHMI is an accessory for the relay which is fully operational evenwithout the LHMI.Section 2 1MRS759142 CREX640 overview62 REX640Technical Manual
