29 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 treadm ills with PWM motor control boards. It is incorporated into the SCR motor control boards. CAPACITOR Stores energy to [...]

30 SIDE FRAME COVERS These sit on top of the frame rails and keep deck in place. They also form the base for the traction strip. IR POTENTIOMETER The IR Pot is located on the PWM motor control board and is used to adjust the time it takes the PWM to react to a load or amperage spike. It normally requires adjustm ent if the motor feels like its surg[...]

31 TREADBELT This is the surface the user walks on. It rides over the deck and rollers. UPPER DISPLAY BOARD This controls information from the Membrane panel and Face Plate. It then tran smits it to the relay board on Home models and the SCR on Club or LTD models. UPRIGHTS One on either side, they house the wire harness, the upper displa y, the cro[...]

32 Testing Components 12 VDC POWER SUPPLY Measure across the input terminals for AC line voltage (120/220VAC). Meas ure across the output wires for DC voltage (9.0VDC to 18.0VDC is acceptabl e). If you confirm proper input voltage (AC) and have no output voltage (DC) the DC power supply must be replaced. Drive Motor: Generation Test – all Landice[...]

33 ELEVATION MOTOR Using your voltmeter measure the input voltage (A C) to the elevation motor. Secure the black (negative) meter probe to a good chassis ground. Plac e the red meter probe on the RED wire in the elevation harness. Press the el evation DOWN key and you should get 120 /220VAC. Place the red meter probe on the BLACK wire in the elevat[...]

34 terminals with your voltmeter. You should m easure 120/220VAC across these terminals. The DC voltage comes out of the SCR board (going to the drive motor) across two output terminals marked MTR+ and MTR-. Confirm DC voltage out by m easuring across these two terminals with your voltmeter. You should measure 90/ 180VDC output. If the SCR board is[...]

35 Common Symptoms Symptom: Treadbelt feels like it’s slipping or grabbing when walked on. Possible Cause: Loose drive belt or treadbelt. Adjust as per manual. Remember to adjust only till slipping stops. DO NOT OVERTIGHTEN Possible Cause : Worn treadbelt and/or deck. If treadbelt or deck is worn it will cause excessive friction and the user will[...]

If there is improvement and there is still room to move driv e roller adjustment bolt, continue to adjust until fixed. 7. If there is no more adjustmen[...]

37 IR POTENTIOMETER ADJUSTMENTS, PWM ONLY: IR = I (amperage) R (resistance) The IR potentiometer that is located next to t he MAX speed potentiometer on the PWM motor control board is used to adjust the time it takes the pwm to react to a load or amper age spike. When the user steps onto the treadbelt a load is introduced to the system which create[...]

38 Speed Calibration: SPRINT 4/PRG/SST CLOSED LOOP (speed sensor) 1. Enter the O.L.S. Mode (Open Loop Speed) by pressing “FAST” and “START” simultaneously. 2. Adjust the max speed first. Bring the se t speed to 12mph. Let actual speed stabilize. 3. Adjust the MAX potentiometer on t he pwm motor control board accordingly. CW = increase speed[...]

39 Removal and Replacement of Components 1. Before beginning any removal or replacem ent of components unplug power cord from wall. 2. Make a note of serial number, model (L7, L8, Ho me, LTD, or Club) and type (Sport, Pro, Cardio, CRT, or Executive). Landice tracks all information fr om this serial number and it must be given when requesting parts [...]

46 NOISES Many times a treadmill will tell you what’s wrong with it by the noises it makes. We strongly recommend the use of an automotive stethoscope. Service Tip: Treadmill making noi se but can’t tell from where. Solution: Must isolate all moving parts. 1) Unplug treadmill. 2) Disconnect Drive Belt. 3) Turn treadmill on, listen for noise. a)[...]

47 6. Is there excess Slip Cote? If you see Slip Cote oozing from sides of belt or off end of deck remove belt and wipe down deck, belt, and rollers. 7. Is it a commercial treadmill? Landice uses a st iffer belt on Club models to increase treadbelt life. These stiffer belts make more noise and are considered normal. 8. On older machines check that [...]

48 Visual Clues The following is a breakdown of things to look for when troubleshooting these components. Decks- Check for wood showing through black phenolic . Check for ridges or cupping of deck especially in front middle of deck. Both of these indicate that deck should be replaced or reversed if other side is unused. Drive Motors - 1. Motor Brus[...]

49 Voltage Tests Variance in voltage affects treadmill per formance. Here is how to trace the voltage into and out of the 8700 series treadmill. Confirm incoming voltage: 120/220 VAC where the line cord attaches to treadmill. It could be; relay board, lower SCR board, terminal block or lower harness. Confirm 12-17 VDC (plug into outlet) output volt[...]
