Code Message Information
Warning Fault Possible causes Remedy
––– E32 Demand Snsr Demand signal failed, Nortec ME Control automatically stopped operation.
Note: If – at any time – the reading of the demand signal is correct again, the system
will continue with normal operation.
Sensor not connected.
Correctly connect sensor.
Incorrect sensor configuration. Correctly configure sensor.
Sensor defective. Replace Sensor.
––– E44 Water Temp Water supply temperature is too high, Nortec ME Control changed to “Fill Cycle”
mode dilution. The fault message must be reset after elimination of malfunction.
Standing Water in inlet system.
Check water supply system.
Insufficient thermal insulation of inlet
pipework.
Insulate supply water pipe.
Water temperature limit set too low. Check/adjust water temperature limit.
Temperature sensor of conductivity sen-
sor configured incorrectly.
Contact your Nortec representative.
––– E45 Water Condu Water supply conductivity is too high, Nortec ME Control changed to “Fill Cycle”
mode dilution. The fault message must be reset after elimination of malfunction.
Water treatment defective/needs service. Check/service water treatment system.
Conductivity limit set too low.
Check/adjust Conductivity limit.
Conductivity sensor configured incor-
rectly.
Contact your Nortec representative.
Conductivity sensor defective. Replace conductivity sensor.
––– E46 Water Outlet Tank drain timeout. The Nortec ME Control stopped operation as the tank could
not be drained within a preset time.
Note: If – at any time – the drain level is reached again, the system will continue
with normal operation.
Drain pump blocked/defective.
Check/replace drain pump.
Drain piping or drain trap clogged. Check/clean drain piping and drain trap.
Level sensor stucked or short circuited. Check/replace level sensor.
Backpressure in drain pipe.
Check drain pipe venting.
––– E47 Level Sensor Water level sensor signal failed. The Nortec ME Control stopped operation.
Note: If – at any time – the reading of the level sensor is correct again, the system
will continue with normal operation.
Level sensor not connected.
Correctly connect level sensor.
Level sensor defective. Replace level sensor.
––– E48 Water Temp Snsr Water temperature sensor signal failed, Nortec ME Control changed to “Fill Cycle”
mode dilution. The fault message must be reset after elimination of malfunction.
Water temperature sensor not connected. Correctly connect water temperature
sensor.
Incorrect water temperature sensor con-
figuration.
Correctly configure water temperature
sensor.
Water temperature sensor defective. Replace water temperature sensor.
W49 ––– Matrix Wash
Over
After installation of new evaporative cassettes a wash over procedure needs to
be carried out. The wash over is mandatory for evaporative cassettes with glass
fibre as evaporator media.
Nortec ME Control is commissioned
first time.
Evaporative cassettes matrix must be
washed over with the Matrix wash over
function in service submenu.
