TROUBLE SHOOTING
IMPORTANT :
If a TCW2043SDD is found to be not working at all or not working properly see that the vaccine
temperature is within the recommended limits. Do not open the lid unless very essential.
For any abnormal sound, smoke, smell etc. in the TCW2043SDD disconnect the unit from power
supply and notify refrigerator technician.
The electronic displays an error message :
F1/ F2 : Probe failure.
The unit will continue to work in “ON/OFF-mode” to keep the temperature in the
desired range - notify Refrigerator Technician.
E1 : Voltage protection cut-out
. The voltage is outside the cut-out setting - check power supply.
E3 : Compressor start error.
The compressor cannot start. keep the unit switched on. This problem
might occur if the solar generator doesn’t deliver enough power (cloudy day, shadow on solar
panels, bad positioning of solar panels etc.). Check the actuals situation of the panels, and if the
problem persists after necessary corrections, notify Refrigerator Technician.
E4 : Minimum compressor speed error.
keep the unit switched on. This problem might occur if the
solar generator doesn’t deliver enough power (cloudy day, shadow on solar panels, bad
positioning of solar panels etc.). Check the actuals situation of the panels, and if the problem
persists after necessary corrections, notify Refrigerator Technician.
E5 : Thermal cut-out of electronic unit.
The ambient temperature is too high, the electronic unit will
run too hot. Switch the unit off. If after one hour the problem still persists, notify Refrigerator
Technician.
HIGH :
The measured temperature is high than +40°C.
LOW :
The measured temperature is lower than -40°C.
