4.3.1 Test platform overload pressure
sensor and platform height sensor (if
equipped)
Instant UpRight specification requires this procedure to be
executed every 500 hours or every six months, whichever
comes first, or when the machine can not lift the maximum
rated load.
Periodic Test Platforms overload pressure
platform height sensors are critical to the safe operation of
the machine. Continuing to use a platform that does not
work properly about overload pressure sensor or platform
height sensor may cause the system to fail to detect the
overload of the platform. The stability of the machine will
be affected, which led to the machine overturned.
Note: Perform this procedure on a solid level without
obstacle on the surface.
4.Turn the key switch to the ground controller and pull the
red "emergency stop" button on the ground and platform
controller to the ON position.
5.Raise the platform by about 4 meters.
6.Raise the safety arm and move it to the center of the
shearing arm and rotate it down to the vertical position.
7.Lower the platform to the safety arm.
The risk of injury. When you lower the platform, keep your
hands away from the safety arm.
8. Turn the key switch on the ground controller to the OFF
position and push the red "emergency stop" button to the
OFF position.
4.3.2 Overload Sensor
1.At the end of the lift cylinder, follow the pressure
sensor cable down to find the end of the shear clip on
the chassis table.
2.Insert the positive pole of the multimeter probe
firmly into the cable rubber sleeve of the pressure
sensor pin A. See the illustration below.
3.Insert the negative pole of the multimeter probe
firmly into the rubber sleeve of the pressure sensor pin
B. See below for illustrations.
Result: The pressure sensor has a voltage reading
of 24V. The input voltage of the pressure sensor is
normal. Proceed to step 9.
Result: The pressure sensor has a voltage reading
of 0V. The input voltage of the pressure sensor is
not normal. Check if there is wiring harness in the
power supply or ground circuit. Check the GC V
sensor at V + output.
