Engel MT45F-U1D-P Service Manual

■ Error Message (Digital display of temperature controller)
Error message will be displayed if the voltage of the battery is low or in the event of any troubles - (see table below).
To reset the error, reset the power
Error message
※1 The voltage detection position is the terminal block of the refrigerator. (The voltages at the battery and terminal block are different to include the wiring drop.)
※2 No error is displayed if the fan is disconnected during operation. An error will occur at startup when the refrigerator is disconnected while the refrigerator is off.
■ About the battery protection function
This refrigerator has a battery protection function for battery protection.
(The above error code <.>)
If the battery voltage is low, the refrigerator stops as shown in the table on the right.
The refrigerator automatically returns when the battery voltage returns to normal voltage.
