5.3 Probes connection
5.3.1 General warnings
If using terminal ends be sure there are no bear parts which could cause short circuiting or
introduce noise disturbance at high frequencies. To minimize the induced disturbances use
shielded cables with the shield connected to earth.
Pressure probe (4 - 20 mA): respect the polarity. If using terminal ends be sure there are no
bear parts which could cause short circuiting or introduce noise disturbance at high frequencies.
To minimize the induced disturbances use shielded cables with the shield connected to earth.
Temperature probe: it is recommended to place the temperature probe away from direct air
streams to correctly measure the temperature.
5.3.2 Probe wirings
Low voltage side (14PINs connector): Keep the cables away from the power cables. Use shielded
cable to lengthen the cables.
NOTE1: The PIN 4 is the common line for the temperature probes
NOTE2: The PIN 6 gives a 12Vdc supply for the 4-20mA pressure transducers
PP07 PP11, PP30, PP50 4÷20mA pressure
transducers respect the polarity.
