GENERAL DESCRIPTION
In combination with a height sensor to measure platform height and a pressure sensor to mea-
sure lift cylinder load, the GP102 control module calculates an estimate of load and prevents
scissor vehicle operation when its platform is overloaded. The system also includes an integrated
tilt sensor that provides a warning alarm for tilted condition. In addition the automatic armguard
cutout and descent alarm are controlled by this system. To access the control module for trouble-
shooting and calibration, the
EZcal
hand held device is required. These are available from MEC
Aerial Platform Sales Corp.
ONLY TRAINED AND AUTHORIZED PERSONNEL SHALL BE
PERMITTED TO CALIBRATE THE PLATFORM OVERLOAD SENSING
SYSTEM.
READ ALL INSTRUCTIONS CLOSELY BEFORE ATTEMPTING EACH
STEP OF THE CALIBRATION PROCEDURE.
