Displays motor voltage
Displays motor current
Displays temperature (°C)
Displays tilt values (X°, Y°)
Displays whether system is in tilted mode (measured tilt exceeds
tilt trip points)
Displays platform height, calculated from height sensor(s) and
data stored during calibration
If two
EZfit
sensors are installed, press ENTER when viewing the
HEIGHT (which is the average of the two sensors), to see the
individual measurements of the two sensors, named HEIGHT1
and HEIGHT2 (press

to see both); press ESC to return
to the average HEIGHT
Displays platform load, estimated from lift cylinder pressure
measurement, platform height, and height/pressure curves stored
during calibration
Displays whether system is in overload mode (platform load
exceeds load trip point, at/above overload height)
Displays whether the most recent platform movement was UP or
DOWN; this is important if the lift cylinder pressure is affected by
the direction of movement (during calibration, separate
measurements are collected during lifting and lowering)
Displays whether system is in elevated mode
