When the Driver board detects an error, it shuts down interrupting the power supply to the tread belt
motor and to the gradient motor and memorises a numerical code that identifies the detected error. It
also sends an error state signal to the Main Board, via serial interface. When the Main Board
receives this signal, it interrupts operation and shows the “EQUIPMENT BLOCKED” message on
the display.
01 1/OH
OVER-TEMPERATURE
detected on the dissipators
inside the D
PFC.
Check the condition of the treadmill;
Check the condition of the treadmill deck;
Check the operation of the fan;
Check the Driver;
(*).
02 2/OC
OVERCURRENT, including
instantaneous ones, on the
driver.
Check the condition of the treadmill;
Check the condition of the treadmill deck;
Check the contacts of the P9 Encoder connector
on the motor side. These must be “regular” and
not loose or jagged. If they are, replace the motor;
03 3/UU
LOW VOLTAGE, due to a
line voltage that drops
si
instantaneously.
Check the condition of the treadmill;
Check the condition of the treadmill deck;
Possible input overload;
False contact in the cable;
Input voltage not constant;
Poor distribution in the electrical system (shared
neutral,
lines too long) or it may be due to a low
voltage transient on the electricity network;
Braking resistance 150 ohms.
05 5/ST
SERIAL TIMEOUT, no data
exchange between High Kit
and Low Kit
Check the serial communication.
06 6/PE
EEPROM ERROR, this is
generated when errors are
detected in the data stored in
the EEprom.
Check the operation of the Driver.
07 7/EdC1
GRADIENT Motor Error.
Check Up/Down Troubleshooting;
Check the limit switch.
