Test the Platform Overload
Pressure Transducer and
Platform Height Sensor - GS-30,
GS-32, GS-46, GS-47 (if equipped)
Genie specifications require that this procedure be
performed annually OR when the machine fails to
lift the maximum rated load.
Testing the platform overload pressure transducer
and platform height sensor regularly is essential to
safe machine operation. Continued use of an
improperly operating platform overload pressure
transducer or platform height sensor could result in
the system not sensing an overloaded platform
condition. Machine stability could be compromised
resulting in the machine tipping over.
Note: Perform this procedure with the machine on
a firm, level surface that is free of obstructions.
1
Turn the key switch to ground control and pull
out the red Emergency Stop button to the on
position at both ground and platform controls.
2
Raise the platform 7 to 8 feet / 2,1 to 2,4 m.
3
Lift the safety arm, move it to the center of the
scissor arm and rotate down to a vertical
position.

At the ground controls, turn the key switch to
the off position and push in the red
Emergency Stop button to the off position.
Pressure Transducer
6
Working at the barrel end of the lift cylinder,
follow the pressure transducer cable down the
scissor stack to its end point, at the chassis
deck.
7
Using the positive post of a multimeter probe,
securely fit the post into pin C of the pressure
transducer cable rubber boot. Refer to the
illustration below.
8
Using the negative post of a multimeter probe,
securely fit the post into pin B of the pressure
transducer cable rubber boot. Refer to the
illustration below.
