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
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:
Last updated 03/06/2017 637-4504 Rev. B
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
On/Off Switch
Onboard Circuit Breaker
EMI Filter
MCB
Power Supply
Data Cable
Display Electronics
Last updated 03/06/2017 637-4504 Rev. B
Power Flow Diagrams
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).
Last updated 03/06/2017 637-4504 Rev. B
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:

Display System Power Flow
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 MCB to cut power to the drive circuit. The message “EMERGENCY
STOP, PRESS STOP TO RESET TREADMILL” will appear on the display electronics.

by pressing the speed keys or
entering the desired speed on
the number keypad.
2. The display electronics
registers the requests and
send information down to the
MCB.
3. The MCB sends VAC to turn
the drive motor.
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.
