connect shield to
earth ground for
EMI / RFI protection.
The operating instructions are very easy. No
need signal adjustment (fitted in laboratory)
The cable is fitted with an internal small tube
for atmospheric pressure compensation. Don’t
block or pressure the tube. Don’t put the end
of the cable in water or flooding area during
the installation, check the correct position of
the cable without dangerous roughness or
sharpness. Don’t use any sharp tool for fitting:
risk of water infiltration.
Check the correct polarity of the connections :
the inversion of polarity is not destructive; in
this case, the signal drops to 0mA.
Connect the lightning protector (PSE30V) on a
very good earth line. Provide a power voltage
supply sufficient to compensate the drop-out
in the current loop and be sure to get a 6VDC
minima on the transmitter : Measure the total
electrical resistance of the line (included all
electronic systems) and apply the following
formula :
U (supply mini) = 6V + (R line x 0.02 A).
In the most cases, a 12 or 24 VDC supply is
sufficient
Warning
: Following the lightning protector
unit fitted with the transmitter,
PSE43V
or
PSE30V
, the power voltage max. is
38V
for
PSE43V and
27V
for PSE30V.
TROUBLE-SHOOTING PROCEDURE
Transmitter checking : Disconnect the transmitter from the system ; Connect the transmitter on a
battery (12VDC or small square 9VDC battery) and introduce a milli-amperemeter in the loop.
Check the current value : 4mA with the transmitter out of water and atmospheric pressure, and
20mA for the full-scale height of water.
For intermediate value :
H (meter) = (Signal (mA) - 4mA) x F.S. (meter) / 16,
and conversely :
Signal (mA) = ((Height (m) / F.S. (m)) x 16) + 4mA
