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.
