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. For Hach GLI 3400
series sensors use Pt1000.
Measure the resistance of
the temperature sensor in the
sensor to make sure of a
correct reading. For Hach
GLI 3400 series sensors, the
resistance between blue and
white wires should be 1089
to 1106 ohms at 23–27 °C.
ERR 11
Current output icon flashes;
current is below 3.8 mA
Measure 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 5.2.2
on page 39 ).
