Trouble-Shooting
How the Patented ProSpot System works:
Starting from the Computer Brain, a signal is sent from the left & right side, thru the L & R Grey
Base Frame Wire Harness (white lead), Locking Post wire harness to the Lower rear Cable
Knuckle connector, to inside Barbell Cable to the Sensor on the Barbell. When skin contacts is
made with Barbell Sensors, the signals return to the Computer Brain, at which a 12-volt charge
is sent via the Base Frame Wire Harness to the contact strips in the Locking Post to the
solenoids, to release the spring loaded Slider Block Locking Pins when the Barbell is lifted,
allowing the Barbell to move up and down. When skin contact with Barbell Sensor is broken by
either hand, the Computer Brain reads this and stops the 12-volt charge to the solenoids, at
which time, the spring loaded Locking Pins instantaneously engages the hole on the Guide Post
and locks the Barbell from any downward movement.
Trouble Shooting of ProSpot Systems
ALWAYS REMEMBER: After performing any service on the unit, RESET the Computer on your
ProSpot system before using it. Just unplug the power supply Electronic Box, wait 30 seconds
and plug back in. Resetting the Computer allows it to recalibrate and work to its greatest
efficiency.
Electrical Service Inspection Checklist:
1. Check for proper functioning of wall receptacle. (Test plug for power)
a. If bad, find new AC power supply.
2. Check wall transformer connection to Electronic Box. Should not be bent or loose.
a. If bad, replace Electronic Box.
3. Check for green flashing light, the indication power to Electronic Box.
a. If no green light, test 12V Wall Adapter for 12-17 volts output. If voltage is less
or none, replace 12Vpower supply.
4. Inspect white connectors from Base Frame Wire Harness connection on Electronic Box
for loose wires.
a. If loose, plug in tight.
b. If broken, replace Base Frame Wire Harness.
5. Inspect Base Frame Wire Harness for possible pinching in frame during assembly.
a. Replace Base Frame Wire Harness if damaged or defective.
6. Inspect Base Frame Wire Harness connection to Locking Post Wire harness.
a. If loose, plug in tight.
b. If broken, replace Base Frame Wire Harness or Locking Post Wire Harness.
7. Inspect Locking Post Wire Harness connection to Contact Strips.
a. If loose, plug in tight.
b. If broken, replace Locking Post Wire Harness.
c. Inspect Locking Post Wire Harness plug in connector to Lower Cable Knuckle.
d. If loose, plug in tight.
e. If broken, replace Locking Post Wire harness.
8. Check contact points of Sensor Weight Bar.
a. If no contact, adjust Sensor Collar closer. So that sensor Collar pin makes better
contact with metal plate on Cable Knuckle.
