  • Page 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 green lights should always be ON when power is supplied to the treadmill. Yellow indicates a treadmill function. Red indicates a treadmill malfunction.
  • Page 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 amperage will increase. When this amperage reaches its max limit, the lower board will shut down its power (treadbelt will slow down / low torque) to the drive motor and the C.LIM LED will illuminate.

  • Page 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.
  • Page 23 LED LIGHTS ON PWM The PWM lower board is designed with two diagnostic LED lights. The LED’s are color coded according to their specific function. LED 1 (red) – This indicates a high current draw similar to the C.LIM LED on our SCR lower control board.

  • Page 29 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.
  • Page 30 Recommended treadbelt lubricant for Landice commercial treadmills. SPEED SENSOR Landice uses a magnetic speed sensor to receive accurate speed readings. Readings are taken directly from the flywheel on the motor and sent to the Relay Board or SCR. Distance between the sensor and the flywheel is critical but the sensor is unaffected by dirt or dust build-up (unlike optical sensors).
  • Page 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 transmits 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 display, the cross member and the handrails.
  • Page 32 (DC) the DC power supply must be replaced. Drive Motor: Generation Test – all Landice drive motors (110 & 220) are direct current or DC. A DC drive motor can produce (generate) a DC voltage when it’s manually rotated. The DC output is linear to the speed the motor is rotated.
  • Page 33 ELEVATION MOTOR Using your voltmeter measure the input voltage (AC) to the elevation motor. Secure the black (negative) meter probe to a good chassis ground. Place the red meter probe on the RED wire in the elevation harness. Press the elevation DOWN key and you should get 120 /220VAC. Place the red meter probe on the BLACK wire in the elevation harness.
  • Page 34 terminals with your voltmeter. You should measure 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 measuring across these two terminals with your voltmeter.
  • Page 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 feel like belt is slipping or grabbing.
  • Page 36 Landice has adjustment on the front roller to correct for this type of problem. The front roller will not be damaged by the adjustment providing these steps are followed. If this doesn’t correct problem please call 1-800- Landice.
  • Page 37 IR POTENTIOMETER ADJUSTMENTS, PWM ONLY: IR = I (amperage) R (resistance) The IR potentiometer that is located next to the 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 amperage spike. When the user steps onto the treadbelt a load is introduced to the system which creates an amperage spike.
  • Page 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 set speed to 12mph. Let actual speed stabilize. 3. Adjust the MAX potentiometer on the pwm motor control board accordingly. CW = increase speed / CCW = decrease speed.
  • Page 39 2. Make a note of serial number, model (L7, L8, Home, LTD, or Club) and type (Sport, Pro, Cardio, CRT, or Executive). Landice tracks all information from this serial number and it must be given when requesting parts or technical assistance.
  • Page 40 12 VDC TRANSFORMER REPLACEMENT (HOME TREADMILLS ONLY) Observe the proper polarity when installing a new DC power transformer. Catastrophic damage can occur to the upper display board electronics if the DC polarity is reversed. 1.

  • Page 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 noise but can’t tell from where. Solution: Must isolate all moving parts. 1) Unplug treadmill.
  • Page 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 stiffer belt on Club models to increase treadbelt life. These stiffer belts make more noise and are considered normal.
  • Page 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.
  • Page 49 Voltage Tests Variance in voltage affects treadmill performance. 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.
  • Page 50 This means you’ll get an LS or L5 error if your PWM is blown, not an OS or 05 error. This is a safety feature on all Landice Home treadmills with PWM Motor Control Boards. The SCR Motor Control Boards also have internal protection to prevent an over speed condition from occurring due to an internal component failure.
