TM to return operation. 2-2 treadmill to SECTION 3. , THEORY OF OPERATION Figure 3-1 shows treadmill components and figure 3-2 shows the functional block diagram for the Q55/Q65 Medical Treadmill. Figure 3-2 is located at the end of Section 3. 3.2 3.1 - The Q55/Q65 Medical Treadmill uses one motor to drive a walking belt, one motor to change the speed of the walking belt and one motor to change the grade (elevation) of the treadmill.., The treadmill is considered Unit 2 of Quinton's Q Series of stress test products. It can be controlled by any of the following treadmill controllers (the controller is considered Unit I): the Q2000 Stress Test Monitor, the Model 645 Programmable Treadmill Controller or Quinton's Treadmill Controller. The Q55 and Q65 are functionally identical and use identical cable interfaces to the various types of controllers. The Q55 operates between I and 10 mph (l.6 and 16 kph), and the Q65 operates between 1.5 and 15 mph (2.4 and 24 kph). A drive motor provides the motive force to turn the treadmill drive pulley and move the walking belt. An arrangement of shafts, belts and pulleys, including a variable speed belt, allows a moveable sheave on the input shaft to affect the rate of rotation of the output shaft and the walking belt. A reversible speed change motor moves the speed change spindle assembly and moveable sheave along the input shaft to effect changes A in the speed of the walking belt. tachometer is linked to the output shaft to monitor the speed of the walking belt. - - PRINTED CIRCUIT BOARD (PCB) INTRODUCTION A grade motor turns a pinion shaft to raise and lower the headframe of the treadmill on two x:ack gears. A grade potentiometer linked to the pinion shaft by a chain and sprockets allows grade change to be monitored. A printed circuit board (PCB) assembly contains electrical and electronic elements necessary for motor control and treadmill controller interface. Signals from the controller initiate start/stop, speed increase or decrese, grade change and grade direction change. Feedback signals from the tachometer, grade potentiometer, drive motor, treadmill control cable and walking belt are routed through the PCB to the treadmill controller. Motor control relays, fuses and electronic circuits are mounted on the printed circuit board (PCB) 2Al. Mounted on the back of the PCB bracket are drive motor contactor 2Kl and transformer 2Tl. Connector 2AIPll on the PCB provides the interface between the treadmill controller (Unit I) and the treadmill (Unit 2). Circuits on the PCB and electrical components are described in this section as they relate to the treadmill subassemblies that they control or monitor. 3.3 POWER SUPPLY Line voltage is available to treadmill control circuits on the PCB when the power cord is plugged in. Power is routed directly through connectors 2AIPI and 2AIP6 to the motors and fan. Line voltage is stepped down through transformer 2Tl before it goes to the power supply circuit on the PCB. Transformer 2Tl also provides electrical isolation from primary power. The power supply circuit uses a diode bridge rectifier, filters and voltage regulators 2Al VR I and 2Al VR2 to supply +24 Vac to the power supply monitor circuit and +12 Vdc and +23 Vdc to other PCB circuits. A +24 Vac power supply monitor circuit uses a rectifier/filter, a low voltage comparator, a pulse stretcher and an output driver to sense and indicate low line voltage. Sensitivity can be adjusted by the trip level potentiometer. When .low line voltage is sensed, the LO VOLTS LED on the PCB lights and feedback is sent to the treadmill controller. A +23 Vdc continuity test circuit on the PCB also monitors the treadmill control cable connection to ensure that there is no break in continuity. A CABLE OK LED lights on the PCB unless there is a break in the plug connection circuit. Feedback goes to the treadmill controller if a break is detected.

An input shaft, an output shaft, belts and pulleys function as a transmission on the 3-3 illustrates this Q55/Q65. Figure arrangement. The following paragraphs describe shaft, belt and pulley operation in detail. 7 n Drive motor contactor 2K 1 turns on or shuts off the drive motor when a signal from the treadmill controller energizes the motor contactor driver latch circuit on the PCB. The +23 Vdc motor contactor driver/latch circuit responds to a START or STOP signal from the treadmill controller. It uses a driver and a latch to keep the motor started or stopped. A signal from the motor overload latch circuit or the EMERGENCY OFF switch overrides any commands to start or stop the motor. The + 12 Vdc motor overload latch circuit uses optical isolator 2Al U5 to monitor a thermal sensor in the motor or motor contactor. When the motor overloads, the optical isolator actuates this circuit to disable the motor contactor driver/latch circuit. The treadmill will not restart until the motor's thermal sensor has cooled and reset and the START switch is pressed. The circuit also lights the MOTOR LED on the PCB and sends feedback to the treadmill controller if an overload condition occurs. The MOTOR LED will stay on until the thermal overload has cleared and the treadmill has been restarted. 3 --8 INPUT SHAFT, OUTPUT SHAFT, BELTS AND PULLEYS 2 ;....--9 1 ;;..---10 r--o----11 -------12 2 3 4 5 6 7 3.5 MOUNT Drive motor output shaft V-belts Machined pulley Input shaft Input shaft fixed sheave Input shaft moveable sheave Input pulley Figure 3-3 14 13 8 Speed change spindle assembly 9 Variable speed belt 10 Timing belt 11 Output shaft 12 Drive pulley 13 Output shaft fixed sheave 14 Output shaft moveable sheave 15 Output pulley ~ 15 Input Shaft, Output Shaft, Belts and Pulleys 3-3 Input Shaft 3.5.1 The input shaft is equipped with a machined pulley, the fixed and moveable sheaves that comprise the input pulley, and the speed change spindle assembly. Two V-belts link the drive motor output shaft with the input shaft. The input shaft turns at a fixed rate. The speed change spindle assembly consists of a fork, a speed change spindle and a yoke. As the speed change motor turns the spindle, the fork moves laterally on the input shaft in tandem with the moveable sheave. 'The ~unction .o.f the speed change spindle assembly IS to posItIon the moveable sheave on the input shaft. 3.5.2 Output Shaft The output shaft is equipped with a spring, the moveable and fixed sheaves that comprise the output pulley, and a timing pulley, The output shaft turns at a variable speed depending on the pitch diameter of the output pUlley. 3.5.3 Variable Speed Belt A variable speed belt links the input pulley and the output pulley. Because the four sheaves in the arrangement are graded, the variable speed belt can be forced in or out between pairs of sheaves to increase or decrease pitch diameter. Spring tension against the moveable sheave on the output shaft tends to force the belt outward, increasing the pitch diameter of the output pulley. When the speed change fork moves the moveable sheave on the input shaft ~nward, the pitch diameter of the input pulley Increases and causes a concurrent decrease in the pitch diameter of the output pulley. This turns the output shaft at an increased rate. 3.5.4 Treadmill Drive and Idler Pulleys The timing pulley on the output shaft drives the treadmill drive pulley. The drive pulley, in turn, drives the walking belt and the treadmill idler pulley. 3.6 WALKING BELT AND BELT TRACKING SWITCHES The walking helt is the tread mill conveyor belt. Two factory-set limit switches on the underside of the treadmill deck monitor the lateral movement of the walking belt. If the walking belt comes close to touching an edge 3-4 of the treadmill drive pulley, one of the switches actuates. If a switch actuates, the BELT LED on the PCB automatically lights and a message is sen t to the treadmill controller that a hazardous condition exists. On the Q2000, the message TREADMILL BELT TRACKING ERROR appears on the screen. On the 645 PTC, the BELT TRACKING LED in the SELF TEST box lights. On the Treadmill Controller panel, the BELT TRACK LED lights. 3.7 SPEED CHANGE MOTOR ASSEMBLY The speed change motor assembly 2A2 consists of a reversible, spli t-capacitor gear motor 2A2M I and the speed change capaci tor 2A2CI. The speed change motor is linked by a chain and sprockets to the speed change spindle assembly that moves the assembly laterally along the input shaft. The speed change capacitor provides the phase shift necessary to start the motor. The motor cannot be operated unless the drive motor is also on. Relay drivers 2Al V3 on the PCB receive logic level signals from the treadmill controller and deliver appropriate voltage to the appropriate speed change motor relay. Speed change motor relay 2AIK3 controls speed increse, and speed change motor relay 2AIK4 controls speed decrease. Relay 2AIK3 is also a lockout relay to prevent both relays from energizing si multaneously. 3.8 TACHOMETER ASSEMBLY Tachometer assembly 2A3 uses an optical emitter and a sensor that run on +12 Vdc from the PCB. The sensor measures the rate of light beam interruptions caused by a rotating beam chopper. The resulting variable frequency pulses are converted by the tachometer circuit into a dc voltage proportional to the speed of the treadmill. The . tachometer circuit uses frequency d.oublmg pulse amplifier 2AI VI and a low pass fIlter (also 2A 1V 1) to convert the variable frequency pulses received from the tachometer. The output of the filter is l'eferenced to +12 Vdc. The tachometer current source then changes the voltage signal to a current signal and transmits the current signal back to the treadmill controller. Tachometer gain potentiometer 2AIR13 allows calibration of the tachometer current source so that 1 milliampere represents a rate of 1 mile per hour. 3.9 GRADE MOTOR Grade motor 2Ml is a right angle gear motor. The motor shaft is linked to a pinion shaft by a chain and sprockets. The chain turns a sprocket on the pinion shaft to raise and lower the headframe of the treadmill on two parallel rack gears. Relay drivers 2Al U3 on the PCB receive logic level signals from the treadmill controller and deliver appropriate voltage to grade change relay 2AIKl or grade direction change relay 2AIK2. Grade change relay 2AIKl starts or stops the grade motor. It works with relay 2AIK2 to increase or decrease grade, depending on the polarity of the direction control windings. Grade direction change relay 2A 1K2 controls the polarity of the direction control windings in the grade motor. The change in polarity does not cause the grade motor to turn, although it alters the direction that the grade motor shaft will spin. The.2 second delay circuit on the PCB delays the signal to relay 2AIK2 to ensure that the grade motor stops completely before changing direction. 3.10 PINION SHAFT AND RACK GEARS The pinion shaft and rack gears allow the entire headframe assembly to tilt for grade increase or decrease. The pinion shaft rotates two sprockets at either end to move up and down a parallel pair of rack gears. Mechanical stops at the top of the rack gears prevent upward overtravel, while the deck prevents downward overtravel. The pinion shaft has a torque limiting device to prevent damage to the grade motor if it continues to turn at the upper or lower limits of travel. 3.11 GRADE POTENTIOMETER Grade potentiometer 2R 1 monitors the rotation of the pinion shaft to indicate changes in grade. The potentiometer is linked to the pin ion shaft by a pair of sprockets and a chain. The potentiometer runs on +12 Vdc from the PCB. The voltage signal from the potentiometer is changed by the grade current source on the PCB to a current feedback signal that goes to the treadmill controller. Grade zero potentiometer 2AIR29 allows calibration of the grade current source when the grade angle is zero so that an increase in voltage represents an increase in grade. Grade gain potentiometer 2AIR30 allows calibration of the grade current source so that a I milliampere change represents a 296 change in grade. 3-5/3-6 Blank FIGURE 3-2 - - - FUNCTIONAL BLOCK DIAGRAM MAJOR COMPONENTS PCB BLOCK MAJOR COMPONENTS 2AI Power Supply Circuit CRI, CR2, CRI7, CR20, VRI, VR2 Continuity Test Circuit CR6 Power Supply Monitor Circuit UI, U3, U4, CR9 Optical Isolator U5 Motor Overload La tch Circuit U4, U5, Q5, CRIO Motor Contactor Driver/Latch Circuit Q3,Q4 Tachometer Circuit UI Tachometer Current Source U2, Q2 Grade Current Source U2, QI .2 Second Delay Circuit U3, U4 Relay Drivers U3 Grade Change Relay KI Grade Direction Change Relay K2 Speed Motor Change (Increase) Relay K3 Speed Motor Change (Decrease) Relay K4 CABLE OK LED CR6 LO VOLTS LED CR9 MOTOR LED CRIO BELT LED CR5 Tachometer Gain Potentiometer Rl3 Trip Level Potentiometer R23 Grade Zero Potent iometer R29 Grade Gain Potentiometer R30 r I TRAW'5FQRMER 2Al ,..

TROUBLESHOOTING - 4.1 INTRODUCTION This section contains fault logic diagrams, test data and waveform graphics to aid in isolating a malfunction to a faulty component. After a faulty component has been identified, refer to Chapter 5 for corrective maintenance procedures. If a failure occurs on the printed circuit board (PCB), component replacement should occur at the factory. For this reason, detailed troubleshooting procedures for the PCB are not included. - - - 4.2 DIAGNOSTIC AIDS Each type of treadmill controller incorporates its own diagnostic aids. Quintonts Treadmill Controller (PIN 14544-001 or 14544-002) is the simplest and has four LEOs on the control panel that correspond to the four LEOs on the PCB of the treadmill. These LEOs show status of the belt switches, cable continuity, voltage to the treadmill and motor overload. The Model 645 Programmable Treadmill Controller (645 PTC) also incorporates diagnostic aids. An automatic initialization test is conducted any time the treadmill is turned on or MASTER RESET is pressed, and information is displayed in the SELF TEST block of the control panel. In addition, a treadmill calibration procedure (Section 6.2 of the 645 PTC Technical Manual) should be performed at installation, once every six months and after maintenance is performed. A complete description of the diagnostic aids built into the 645 PTC can be found in Section 5.3 of the 645 PTC Technical Manual. The Q2000's diagnostic aids are described in Section 4 of the Q2000 Service Manual. The Q2000 also conducts an automatic initialization test each time it is turned on or reset, and error messages are displayed on the screen. Treadmill calibration (Steps 1, 2 and 7 of Section 4.4 of the Q2000 Service Manual) should be performed at installation, once every six months and after maintenance has been performed. 4.3 TROUBLESHOOTING PROCEDURE The fault logic diagrams that follow are designed to lead you through an operability test of the Q55/Q65 Medical Treadmill. They aid in isolating a malfunction to the treadmill or to the treadmill controller. A square on the diagram indicates a procedural step, and a diamond on the diagram indicates a decision point. Figure 4-1 shows the waveform needed to troubleshoot the tachometer. NOTE Servicing your own equipment while it is still within the warranty period may void the warranty.
