Section 4- Servicing Landice Treadmills
DEFINITIONS
12 VDC POWER SUPPLY
(Transformer)
This transformer converts AC power to DC power. It provides low voltage current for the Upper Display
Board. This component is found on treadmills with PWM Motor Control Boards. It is incorporated into the
SCR Motor Control Boards.
CAPACITOR
Stores energy to smooth out voltage to Drive Motor. Used with SCR Motor Control Boards.
CHOKE (Inductor)
Acts like a filter to smooth out voltage to Drive Motor. Used with SCR Motor Control Boards.
DCP (DISPLAY CONTROL PACKAGE)
Package containing all components relative to the Upper Display Console. This includes the
membrane/faceplate, upper display board, & wire harness. DCP’s also include owner’s manuals warranty
card’s, and cardio pulse transmitter strap (if applicable). DCP’s are for
HOME TREADMILLS ONLY,
that
are shipped without upper electronics.
DECK
Wooden board 1” thick with a phenolic coating. Treadbelt rides over it. Reversible.
DRIVE BELT
This connects Drive Motor to Sheave (Pulley) on Drive Roller.
DRIVE MOTOR
Provides power to Drive Belt to turn Pulley on Drive Roller to move Treadbelt. This gets its power from the
PWM or SCR. Landice Drive motors are either 110v for 220v.
DRIVE ROLLER W/ SHEAVE
This is the Roller at the front of the Treadmill. The Sheave (pulley) is pressed onto the roller and allows
transfer of movement from Drive Belt to Treadbelt.
ELEVATION LEG ASSEMBLY
Connects to Elevation Motor to allow movement of front of treadmill up or down.
ELEVATION MOTOR
This motor works through the elevation leg assembly to raise or lower the front of the treadmill. It gets its
power from the Relay Board on Home models and from the SCR on LTD and Club models.
ELEVATION POTENTIOMETER
Attaches to Elevation Motor and gives feedback to Upper Display as to what incline the treadmill is at.
Needs to be calibrated whenever elevation motor is replaced. A Potentiometer should be checked
whenever there is a problem with elevation or when Error Code PO comes up.
