conSole code errorS

During calibration, all 3 electronics, could display:
"CaL faIL" aUtO CaLIBRatIOn HaS ExCEEdEd 3 MInUtES
NOTE: Error is normally speed related.
• Make sure the PWM does not exceed 250.
"CaL faIL ERR EL" IndICatES GRadE POt OR GRadE MOtOR faILURE
• Check wire connection especially connection from actuator to LCB and from LCB to upper board by
making sure there is no loose connection. If no loose connection change the code/wire. In case none of
these work change the actuator (in isolated incidences you may need to change LCB).
• Before changing parts try to recalibrate the unit this in some cases solves the problem.
• Could be due to any of the Grade Errors Listed Below.
NOTE: LE Operating error codes will freeze electronics. Switch by power cord must be recycled - turn the
switch off for 30 seconds.
"ERR LS" IndICatES LOSS Of SPEEd SEnSOR SIGnaL
NOTE: If belt moves Sensor could be out of position or wire connection.
If belt does not move wire connection or Lower Control Board.
• If you had belt movement before this error was displayed, check speed sensor and make sure it is close
enough to pick up a signal from the magnet. Also try to manually move the belt and see if LED (DT16) will
light up.
"ERR OS" OvER SPEEd
NOTE: Signals indicate belt is moving faster than speed called for by 3 MPH or higher.
• Check sensor position and recalibrate.
"ERR GRd1" GRadE MOtOR StaLLS OR OvERHEatS
Occurs when grade change is called for but pot signal does not change in 4 seconds.
• Check grade LED bulbs on Lower Control Board (LCB) when grade up or down is pressed to assure signal
is received at LCB.
NOTE: If DT11 is lit on LCB use voltmeter to check for household voltage between Elevation WHITE wire
and BLACK wire. If it is lit but there is no voltage then replace LCB. Or if there is voltage but no
