Chart 3: Error symbols and their causes
Cause
● Re-balance the samples; the maximum error allowed is
● The device is placed in a leaning position, not horizontal;
● The motor shaft is bent; equipment needs to be
repaired by Technical Service Department.
● Problem of microcomputer control system; equipment
● Problem of speed sensor; equipment needs to be repaired
by Technical Service Department.
● Re-close the lid

is
● Lid protection system is broken; equipment needs to be
repaired by Technical Service Department.
● Check the power source
● The Power source voltage is too low or the braking
resistor failed or brake too fast; equipment needs to be
repaired by Technical Service Department.
● The Power source voltage is too low or the
acceleration is too fast; equipment needs to be
repaired by Technical Service Department.
● Speed sensor or motor failed; equipment needs to be
repaired by Technical Service Department.
