Set up for pressure transmitter 2 wires signal 4÷20mA
With pressure transmitters first we need to enable their power supply: remove the part as shown below, then,
on the CPU unit, move the bridge from Pt100 to +Vt
Verify wiring of the sensor

Transmitter
1,6bar 3bar 10bar 16bar 25bar 40bar
Set-point 1bar 1,5bar 6bar 6bar 6bar 6bar
To modify it directly use "up" and "down" arrows.
By pushing F you go to parameter:
Transmitter
1,6bar 3bar 10bar 16bar 25bar 40bar
Hy.P 0,2bar 0,5bar 0,5bar 0,8bar 1,25bar 2bar
Hy.n 0bar 0bar 0bar 0bar 0bar 0bar
Keep pushing F until you see PASS, release F and through the arrows set 99, push F and visualize Pro
(protection code) default is 12, through the arrows set 128 and push F, keep it pushed until all parameters
InF, CFG, InP, Out, PASS are visualized.
