CODE CLASS DESCRIPTION MACHINE SOLUTION
02B2 C Safe key action response T
a. Check the connection of the safety key (emergency stop) switch. If
the switch is always open or shorted out, replace the switch.
b. If the emergency stop does not resolve the issue, replace the PCB.
02B4 C Resistance Type Error ESHURA
a. Make sure machine type is set for the correct frame in console.
- If yes, replace LCB.
- If no, change to correct type and reboot the power.
02B5 C
Inverter sensor the normal
rated current over 150% ,
can hold 60 sec
T
a. Replace MCB.
02B6 C Speed up have over current T
a. Check the condition of the running deck and belt. Replace the belt
and flip or replace the running deck as needed.
b. Replace the MCB.
02B7 C Speed down is overcurrent T
a. Check the condition of the running deck and belt. Replace the belt
and flip or replace the running deck as needed.
b. Replace the MCB.
02B8 C Running status is overcurrent T
a. Check the condition of the running deck and belt. Replace the belt
and flip or replace the running deck as needed.
b. Replace the MCB.
02B9 C
The inner memory IC data
write error
T
a. Reboot power, if error shows again, replace the MCB.
02C0 C DC brake in manual mode C
a. Check if the DC brake is in the “Right “lock position. Release the
brake (move to the left) if in lock position.
b. Replace the brake.
02C1 C Speed tracking error C
a. Adjust the speed sensor position and clean the speed sensor of any
debris.
b. Check the ECB extension cable connection at the LCB (pins 1 &
3 for ECB1, pins 2 & 4 for ECB2), there should be between 12.8 ~
14.2 ohms, check which ECB is outside the range and replace it.
02C2 C
CZ 3IR sensors have no
communication or discon-
nected over 3 seconds
C
a. Check if there’s something blocking the control zone 3 IR sensors.
b. Check if the control zone 3IR sensors (transmitter and receiver) are
aligned.
c. Check the connection of the control zone extension cable from the
transmission board to the receiver board.
d. Replace the transmission board or control zone extension cable as
needed.
02C3 C Frame IR sensor error C
a. Check if there’s something blocking the frame IR sensors.
b. Check if the frame IR sensors (transmitter and receiver) are aligned.
c. Check the connection of the frame IR transmitter cable from the
LCB to the frame IR transmitter sensors.
d. Replace the frame IR transmitter cable if the cable is defective.
02C4 C
The frequency error form
control zone
C
a. Replace the control zone transmission board or receiver board.
02C5 C
The frequency error for frame
IR sensor
C
a. Replace LCB.
02C6 C
The receiver disconnection
for control zone
C
a. Check the connection of the control zone extension cable from the
LCB to the control zone.
b. Replace the receiver board.
02C7 C
The receiver disconnection
for frame IR sensor
C
a. Check the connection of the frame IR receiver cable from the LCB
to the frame IR receiver sensor.
b. Replace the frame IR receiver cable.
0201 A LCB battery low voltage ESA a. Plug in the machine to charge battery for 24 hours.
0247 B LCB fail ESHURA a. Replace LCB.
0248 B
Battery disconnection or
fail ( LCB battery voltage is
less than 6 volts )
ESHURA
a. Check battery wire connection to LCB.
b. Check to see if the battery voltage is less than 6 volt.
- If less than 6 volt, replace battery.
- If not, replace LCB.
