  • Page 59 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 60 1. MOTOR COMPONENTS 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 62 SPEED SENSOR The speed sensor can be checked for proper operation by entering the Open Loop Speed Mode. (See page 56) There is a yellow SPD LED mounted to either the relay board (HOME PWM models) or the SCR board (LTD and CLUB models). The light will flash ON and OFF when you rotate the drive motor flywheel slowly by hand.

  • Page 65 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 66 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 67 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 68 SPEED CALIBRATION: L-SERIES PWM TREADMILLS 1. Enter the O.L.S. Mode (Open Loop Speed) by pressing “MENU” and “START” simultaneously for Executive Trainers and “FAST” and “START” for all other models. 2. Adjust the max speed first. Bring the set speed to 12mph.

  • Page 80 Before attempting to troubleshoot the “receiving portion” of the HRC feature, CONFIRM THE TRAMSITTER BELT IS WORKING PROPERLY. You can test the user’s transmitter belt on another Landice treadmill or a Polar® wristwatch. If the transmitter is faulty, replace battery or return to Landice for replacement (if treadmill is under warranty).

  • Page 88 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 89 7. 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. 8. 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 90 Decks and VFX - Decks are solid pieces of wood with a phenolic coating that rest on the VFX cushioning system. 1. The deck can make a squeaking noise when the VFX hardware is not properly tightened or lubricated. You can test for this by bouncing on the deck when the machine is not running. 2.

  • Page 92 VOLTAGE TESTS Variance in voltage affects treadmill performance 1. Confirm incoming line voltage: 120/220VAC – Measuring between Hot and Neutral on relay board. PWM Units: Measuring between L1 and L2 wires on PWM board. Measuring between Hot and Neutral on SCR board. SCR Units: For 115V and 230V rated PWM’s acceptable variance is + or - 8%.

  • Page 93: Diagnostic Guide

    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.
  • Page 94 Finally, in the rarest of cases, on home treadmills, a faulty relay board can cause an OS. To verify this, using a digital voltmeter, and with the treadmill turned on, measure the DC voltage between V+ and P1 on the PWM board. The reading should be between 6-7VDC. Also measure the DC voltage between P1 and P2 on the PWM.

    L-SERIES EXECUTIVE TRAINER ERROR CODES: The Executive Trainer software is designed with special error codes to display when experiencing a system failure. Here is a list of error codes, their meanings and diagnostics. Error Code: SAFETY SHUTDOWN / Loss of signal (WITH belt movement) Meaning: upper display is not receiving signal from speed sensor.
  • Page 96 This screen will be displayed in diagnostic mode after OK button is pressed. Diagnostic Mode: you must press the OK button in order to proceed with troubleshooting the elevation system failure.

  • Page 112 ROAD RUNNER SUPPLEMENTAL ASSEMBLY INSTRUCTIONS (Follow these instructions in conjunction with Step 10 on page 3 of your manual.) On the Road Runner, there are three wire harnesses that must be connected after the upright assembly is mounted to the frame of the treadmill. The main harness (9 multicolored wires in a gray sheath) should be routed under the elevation motor and secured with the supplied harness restraint clip or wire tie.
  • Page 113 Route the CD changer harness behind the elevation motor, then around the back of the CD changer. Insert the connector into the side of the changer. It will snap when properly connected. Examine all wires around the elevation motor and drive motor to be sure they will not contact any moving parts.

  • Page 117 TRACKING AND TENSIONING Proper tensioning of the Treadbelt and Drive Belt are necessary to insure smooth operation and long life for your treadmill. As these components may stretch as part of their normal break in period it is one of the few things we ask our customers to do in maintenance of their treadmills.
  • Page 118 TREADBELT TRACKING The Treadbelt is TRACKED by means of two adjustment bolts (9/16" wrench) located at rear of treadmill. By tightening the side the belt is closest to and loosening the opposite side by the same amount, you change the alignment of the rear roller without changing overall tension. Adjustments should be made with treadmill running, and should be made in 1/4-turn increments.
  • Page 119 Example: Treadbelt is tracking to the right hand side. Adjust right hand side of drive roller by moving it towards the front (motor side) of treadmill. The Treadbelt will move towards the center. Recommended Maintenance Home Models- Vacuum around and underneath the treadmill on a monthly basis. Vacuum or wipe down the deck area between the treadbelt and frame.
  • Page 120 When to lubricate: Landice L-Series institutional treadmills should be inspected on a monthly ba- sis. By sliding your hand underneath the treadbelt you can feel if the surface of the deck is dry. If the deck surface feels dry then the treadmill should be lubri- cated.
