Power Requirements
Treadmill Dedicated Circuit Requirement:
Star Trac requires a 20 amp dedicated circuit and dedicated neutral for each treadmill installed
and operated. Each treadmill requires an outlet of which line and neutral contacts are wired to
the electrical power distribution box (circuit breaker box) with dedicated wires. Both the line and
neutral wire from an outlet for a treadmill shall be isolated from all other outlet contacts other
than the connection at the electrical power distribution box. The neutral bar of the electrical
power distribution box requires a connection to the earth ground.
Furthermore, there shall be no other electrical device operated off this circuit; just the single
treadmill. The earth ground connection of the outlet may be shared with other outlets’ earth
ground connections through either metal conduit or ground wire.
Each dedicated circuit requires 12 gauge wire for the line and neutral wires for runs less than
100 feet, as measured from the circuit breaker to the termination of the plug (outlet) connecting
to the treadmill. Runs greater than 100 feet require 10 gauge wires, and a run from a circuit
breaker shall not be greater than 200 feet.
Failure to meet these requirements may cause intermittent treadmill shut-down and potential
damage to the treadmill’s electronic components, and consequently, void the warranty.
Last updated 03/06/2017 637-4504 Rev. B
Page 10
Product Placement
Star Trac recommends that treadmills be spaced a minimum of 20.0 inches (0.5 m) apart to
allow safe and easy ingress and egress. More importantly, there must be at least 48 inches
(1.25 m) of free space behind the treadmill.
The E-Series treadmill measures: 85” l by 36.0” w (215.9 x 91.5cm). See the following graph for
proper equipment spacing requirements:

Preventative Maintenance
This section provides a list of factory recommended PM requirements. Long-term effects and
cost comparisons usually favor following a regular preventative maintenance schedule over
performing maintenance actions only when the system fails.
Preventative Maintenance Cautions
While maintaining equipment you will want to avoid spraying any liquids directly onto any surface
of the unit. Always spray cleaning solutions onto a clean towel first then wipe the unit.
While vacuuming the floor area using an upright vacuum, avoid getting the power cord caught in
the beater-brush of the vacuum.
Disconnect the power cord from the wall before vacuuming under the shroud.
Use extreme caution while vacuuming around wires and/or electrical components under the
shroud.
Do not attempt to clean the running belt with a mop
Do not apply any cleaners, protectants or solutions onto the running belt (i.e. Armor All,
SlickStuff, belt dressing, etc.)

Treadmill Systems
Power System
The power system supplies AC and DC voltage to different components of the treadmill. There
are two parts of the power system, external power and internal power.
There are two sub-systems:
External
Internal
External
The external power is anything outside of the treadmill that supplies power.
Components:
Breaker Box
Wall Breaker
Power Lines
Dedicated/isolated lines
Neutral Line
Hot Line
Ground Line
Receptacle
Internal Power
The internal power is the components of the treadmill that are involved with power distribution.
Components:
Power Cord

1. AC power goes from the
breaker box, through the
circuit breaker and power
lines to the power outlet.
2. AC power continues up
through the power cord,
through the onboard circuit
breaker, on/off switch, and
EMI filter to get to the MCB.
3. The MCB converts the
power to 12.6 volt VDC to
send up the display cable
to power up the display electronics.
4. The MCB doubles the
incoming voltage (110 volt
systems only) and sends
220 VAC to the power the
drive motor. The MCB also
sends 6 VDC to power the
RPM sensor.
5. The MCB sends VAC to
power the elevation motor.
The power being sent will
depend on the input voltage.
110 VAC treadmills have a
110 volt elevation motor.
220 VAC treadmills have a
220 VAC elevation motor.
The MCB also sends 5 VDC
to the elevation sensor (potentiometer).
6. The MCB passes along the
input VAC to the power supply. The power supply
then converts the input
voltage to 12 VDC and
sends it up to the display
electronics to power the
fans (PVS kit or embedded
touch screen).

Display System
The display system controls and commands most of the functions of the treadmill. It is the user
interface and the brain of the treadmill.
There are five sub systems:
1. Treadmill Operation
2. Watch Dog
3. Personal Cooling Fans
4. Heart Rate
5. Hot Bar/Warm Bar
Treadmill Operation
Treadmill operation is those functions and components that the user interacts with while working
out on the treadmill.
Components:
Main Keypad (Display Panel)
Display Electronics
Data Cable
Watch Dog
The watch dog is the circuit/software inside the display electronics that monitors the different
systems in the treadmill. If there are any anomalies, the watch dog triggers any of the various
codes that will show up on the screen.
Components:

1. The user presses the keypad to select programs, speed, elevation etc. Those
keystrokes are received by the display electronics which sends the necessary requests
down the data cable to the MCB.
2. The watch dog is a part of the display electronics that monitors the systems of the
treadmill and will shut down the system if there are any anomalies.
3. The user presses the fan keypad to turn the fans on/off or change the speeds. The
display electronics receives the signals and sends the appropriate VDC to the fans.
4. The user grips the contact heart rate grips. A small amount of voltage is sent through
the grips and wires to the contact heart rate board. The contact heart rate board
calculates the Beats Per Minute (BPM) and sends this information to the display
electronics. If the user is wearing a Polar chest strap, signals from the strap will be
received by the Polar receiver. Those signals are sent to the display. The display will
display the BPM of the user’s heart.
5. When the user presses the stop button, the circuit opens (confirm that) and the display electronics triggers the treadmill to: (a) pause on the first press, (b) end the program on
the second press and (c) give a ‘NO STOP’ code if the key is held for longer than 2
number of seconds. If the lanyard is pulled, the emergency stop circuit opens up and a
signal is sent to the MCBto cut power to the drive circuit. The message “EMERGENCY
STOP, PRESS STOP TO RESET TREADMILL” will appear on the display electronics.

4. The drive motor pulley is
connected to the headroller..
5. As the drive motor turns the
RPM sensor signal is sent to
the MCB.
6. The MCB sends the signal
back to the display electronics.
7. The display electronics
calculates that information to
determine the speed of the
drive motor. If the drive
motor is running too fast/slow,
the display will send signals to
the MCB to adjust the voltage
going to the drive motor until
the speed is correct.

17. Replace tail roller through the belt and mount
to the chassis of the machine with the two
bolts.
Tension bolts equally, as they are responsible
for overall belt tension as well as tracking.
18. Ensure proper tracking and re-tension belt
using stomp test.
Adjustments:
The running belt and its headroller, drive belt, tailroller, and running deck are designed to be
self-centering, slip-free, and smooth-operating without the need for frequent adjustments.
Running belt sideward movement, slipping, or grinding after extended use, or thumping during
initial use, may be corrected by the following procedures:
Belt Tracking:
If the running belt is not centered on the tailroller and is either too far left or right, adjust tracking
using the following steps:
1. Turn the treadmill on. Increase treadmill speed to 3.0 mph (5.0 kph).
2. Adjust tracking by turning the left Allen screws (located at the back sides of the tailroller)
with a 1/4" Allen wrench in 1/4-turn increments. If the running belt is tracking to the left,
turn the screws clock-wise in 1/4 turn increments. If the running belt is tracking to the
right, turn the left screw counter-clockwise in 1/4 turn increments.
3. NOTE: ONLY USE THE LEFT SCREW FOR TRACKING ADJUSTMENT.
4. After the running belt appears to be tracking properly, increase the treadmill speed to
10.0 mph (16.0 kph) and verify that the belt stays centered.
Stomp Test - Slipping-Running Belt:
Remove the motor shroud and operate the treadmill slowly at 1 to 2 mph (2 to 3 kph). While
observing the headroller, walk on the belt and try to slow it down by gently applying pressure
with your feet while holding the handrails. If only the running belt, and not the headroller, slows
down, tighten the running belt by turning both the right and left tailroller adjustment bolts clock
wise 1/4-turn. Repeat this adjustment until the running belt no longer slips; ensuring that you
turn both tailroller bolts an equal number of turns. Re-install the motor shroud. If the headroller
and the running belt both slow down, tighten the drive belt.

The care and maintenance of the head and tail rollers are as important as the care and
maintenance of the running belt. Dirt buildup on the rollers can cause noise, rough feelings and
unwanted belt tracking.
Cleaning:
Scrape any dirt and debris build up from the roller using a plastic scraper or an old credit card.
Do not use anything metal or sandpaper, as you will damage the coating on the roller. Vacuum
up any debris from the rollers.
Roller “DO NOT’s”:
• Do not lubricate the roller bearings. They are a sealed type bearing and any lubricant you
attempt to apply, will not penetrate the seal.
• Do not scrape a roller with metal. Use a plastic scraper or a credit card only.
• Do not use sandpaper to clean the rollers

Solution:
__ G1_______
Consult with
electrician to fix AC
input rail voltage.
Note: The AC rail
voltage with a load
should never drop
greater that 5 volts
deferential comparing
it with no load. There
are many equations
to measure for low
rail voltage.
Example: If you take
a person that weighs
200 Lbs at the speed
of 5 MPH, and the
voltage drops greater
that 5 Vac. The wall
voltage is not
adequate and will
cause intermittent
200 DFR codes.
__ G2_______
Replace EMI Filter
__ G3_______
Replace MCB
Start
Turn the tread AC power off.
Measure AC voltage out of the
wall circuit.
Was the AC voltage within
the specs listed above?
The AC voltage should be
approximately:
95 to 120 for 110v unit
The AC voltage should be
approximately:
185 to 250 for 220v unit
