Connection of the signal transmitters (in the models LDI35.AV0 - 20mA):
• 2 wires: signal to the measuring input; power supply to terminal 6;
jumper also terminals 4 and 5; loop impedance 60 to 80
Ω
(load 20mA).
• 3 wires: signal to the measuring input; power supply to terminals 5 and
6; jumper also terminals 4 and 5;
• 4 wires: signal to the measuring inputs; power supply to terminals 5 and 6.
Connect LDI35.CF (thermometer) as shown in the figure. For temperature/
resistances only: if there are two wires only, jumper terminals 3 and 4.
PRELIMINARY OPERATIONS
