ERR 03
Temperature sensor icon
flashes; open or short circuit;
temperature range exceeded
Test the temperature sensor
wiring.
Make sure that the correct
temperature sensor was
selected in the configuration
menu (GLI/Hach 3700 series
sensors use Pt1000).
Measure the resistance of
the temperature sensor in the
sensor to make sure of a
correct reading. For GLI/
Hach 3700 series sensors,
the resistance between red
and yellow wires should be
between 1090–1105 ohms at
23–27 °C.
ERR 11
Current output icon flashes;
current is below 3.8 mA Check the loop power supply
voltage to the transmitter.
ERR 12
Current output icon flashes;
current is above 20.5 mA
Measure the loop power
supply voltage to the
transmitter.
ERR 13
Current output icon flashes;
reading range value set too
large or too small
Make sure that the 4–20 mA
output range settings cover a
wide enough range and are
correct (see
section 5.2.1
on page 36 )
ERR 33
Sensocheck icon flashes;
Sensoface icon active (see
section 10.2 )
Test the primary (send) coil
Temperature icon flashes;
independent of Sensoface
icon (see
section 10.2 )
Make sure that the
temperature is within the
range of the temperature
compensation table
(temperature compensation,
concentration, salinity)
