RT= Characteristic impedance of the cable
(e.g. 120Ω for Belden cable 9841 - 9842).
The end resistances are only inserted
on the first and last RS-485 nodes in the
terminals where the cable is connected.

PHASES' SEQUENCE DETECTION
Press OK. to check the connection of the phases. The error message ERR 123
appears on the display if the connection is wrong.
HOUR METER
The hour meter counts the hours and minutes of operation. The function is active
when the system detects the presence of the L1 phase.
