17 8700 COMERCIAL MOTOR PAN COMPONENTS.
18 8700 COMMERCIAL LOWER WIRING SCHEMATIC.
19 LED (light emitting diode) configurations: SCR lower board The SCR lower board is designed with diagnostic LED lights. The LED’s are color coded according to their specific function. Green indicates a properly operating treadmill; the gr een lights should always be ON when power is supplied to the treadmill.
20 C. LIM (red) – The C.LIM or Current Limit LED should NEVER come on. This diagnostic light is used to determine the condition of the treadbelt and deck. The SCR board has a built-in amp meter. When the treadbelt belt and deck system wears, the am perage will increase.
21 8700 HOME SST VFX, PRG VFX, SPRINT VFX CLOSED LOOP (SPEED SENSOR).
22 8700 SST, PRG and SPRINT VFX TREADMILL All VFX treadmills utilize CLOSED LOOP speed control. All treadmills listed as VFX in the warranty database use a speed sensor.
23 LED LIGHTS ON PWM The PWM lower board is designed with two diagnos tic LED lights. The LED’s are color coded according to their specific function. LED 1 (red) – This indicates a high current draw simila r to the C.LIM LED on our SCR lower control board.
24 LED (light emitting diode) configurations: RELAY BOARD The RELAY board is designed with diagnostic LED li ghts. The LED’s are color coded according to their specific function. Green indicates a properly operating treadmill; the gr een lights should always be ON when power is supplied to the treadmill.
25 8700 SST, PRG and SPRINT 3, NON VFX TREADMILL All NON VFX treadmills utilize OPEN LOOP speed control and no relay boards. Sprint 3 treadmills have push button controls.
26 8700 SPRINT 2 Safety lanyard , speed control dial (not push button), KBWT-110 SCR motor control.
27 8700 SPRINT 1 – LOWER WIRING SCHEMATIC NO safety key, speed control dial (not push button), KBLC-118 Motor Control Board.
28 8700 SPRINT 1&2 UPPER WIRING SCHEMATIC.
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.
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.
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.
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.
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.
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.
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.
36 5. Tighten drive roller until star washer bites into aluminum frame, start treadmill, and adjust tracking. If belt is straight then put on motor cover. If belt is still not straight, go to #6. 6. If there is improvement and there is still room to move driv e roller adjustment bolt, continue to adjust until fixed.
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.
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.
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).
40 12 VDC TRANSFORMER REPLACEME NT (HOME TREADMILLS ONLY) Observe the proper polarity wh en installing a new DC power transformer. Cat astrophic damage can occur to the upper display board electr onics if the DC polarity is reversed. 1. If your DC transformer has color coded fast-on (pus h on) connectors: Blue - negative (-) Red - positive (+) 2.
41 MEMBRANE PANEL 1. Remove control panel end caps from upright assembly. 2. Remove membrane panel and display board assembly by releasing Velcro. 3. Disconnect upper wire harness from display board. 4. Remove screws securing display to membrane panel.
42 ELEVATION MOTOR 1. Remove Elevation Motor. A. Remove all weight from the elevation assembly by placing a suitably strong object under the under motor pan (toolbox) so that the wheels are in the air. B. Disconnect elevation motor harness from lower board or lower harness.
43 To Enter Diagnostic Mode: Turn off the treadmill. SPRINT-1 & 2 (Press DISPLAY & turn Knob to the ON position simultaneously) SPRINT-3 & 4 (Press DISPLAY & START simultaneously) SST & PRG (Press UP & START simultaneously) CLUB & LTD (Press DISPLAY & START simultaneously) To calibrate the potentiometer 1.
44 ELEVATION LEG ASSEMBLY 1. Remove plastic motor cover. 2. Remove set screws (2) holding elevat ion motor to elevation leg assembly. 3. Remove elevation pins from elevation gear nut. 4. Carefully turn treadmill onto its side to gai n access to elevation leg mounting brackets.
45 Drive Roller/Front Roller 1. Release all treadbelt tensi on. 9/16" bolts on rear roller. 2. Remove drive belt from drive motor. Release tension on drive motor tensioning hook (7/16" nut located underside of motor pan). Pivot motor towards treadbelt and slide drive-belt off.
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.
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.
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.
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.
50 Diagnostic Guide Error Codes LS or L5- Loss of signal. See Flowchart for LS pages 55,56,62,63 OS or O5- An OS or 05 error indicates a treadmill O ver S peed condition. This occurs when the actual treadbelt speed is faster than the desir ed selected speed.
