ERROR
CODE
ERROR TYPE
E1
Battery protection
(The voltage is outside the cut-out setting).
E2
Fan over-current cut-out
(The fan loads the electronic unit with more than 1A
peak
).
E3
Motor start error
(The rotor is blocked or the differential pressure in the refrigeration system is too high (>5 bar)).
E4
Minimum motor speed error
(If the refrigeration system is too heavily loaded, the motor cannot maintain minimum speed
1,850 rpm).
E5
Thermal cut-out of electronic unit
(If the refrigeration system has been too heavily loaded, or if the ambient temperature is high, the
electronic unit will run too hot).
E6
