Display and Operating Interface
Display and operating elements in IP 66 field housing
Display (LCD)
– 4½-character display, optional lighting
– with segment display of current in 10 % steps
–
Display elements: error, signal overflow or underflow,
communication
LEDs
– one yellow LED each for indicating the switching status
of the relay (lit = relay energised)
– one yellow LED error indication (lit = error-free operation)
– one green LED indicates error-free indication
(lit = error-free operation, flashing = warning)
Counter
– FMU 861 standard only, FMU 862 optional
– Version: six-character, cannot be reset
Software counter
– FMU 861 standard only, FMU 862 optional
Communication interfaces
Handheld terminals
– INTENSOR: Commulog VU 260 Z
–
HART: Universal HART-Communicator DXR 275
Commuwin II operating program from Hauser
– via Commubox FXA connection to serial interface
RS 232C of a PC
Rackbus RS 485
