VEVOR XRJF-21 - Fault Alarm Interface; Understanding Fault Codes

On the setting inteace, press "Fault Que" on the touch screen to enter the fault que mode.
Displays an alarm inteace when a fault occurs during machine operation.
55 Low speed alarm: 220V machine motor speed is lower than 130 rpm to stop the alarm to prevent
the motor from being damaged by excessive force. (The motor speed of the 120V machine is lower
than 165 rpm and it will stop and alarm.)
LL sensor is abnormal: When the motor is in working state but has no speed, it will stops and alarms
to prevent the motor from being stuck and damaged or the speed sensor being abnormal.
88 Refrigeration poor alarm: if the longest forming time is exceeded, the poor refrigeration alarm will
be repoed.
UH high voltage: when the operating voltage of the machine is higher than the set value, it will stop
and alarm, 220V machine will alarm if it is higher than 255V, and 120V machine will alarm if it is higher
than 135V.
UL low voltage: when the operating voltage of the machine is lower than the set value, the machine
will stop and alarm, the 220V machine will alarm if it is lower than 182V, and the 120V machine will
alarm if it is lower than 96V.
AH return air temperature is abnormal: when the material cylinder temperature probe is damaged
or abnormal, it will stop and alarm.
Clear fault: clear all faults and re-test.
