Attention:
a. Each operation of the button shall last for 0.15s – 2.5s;
b. The calibration will be terminated when any operation of the button exceeds the limit,
and in this case, the calibration shall be performed again from the very beginning.
c. After the horn sounds 5 times, it suggests that the machine has entered the calibration
procedure correctly.
d. When the platform covers the whole travel and stops at the bottom, and the horn
stops sounding, it suggests that the calibration has been finished successfully.
2) The frequent test of platform overload mechanism is essential to the safe operation of machine.
The continuous wrong operation of platform can cause the reaction failure to overload information
of the system. The stability of machine will be affected and even the equipment may be tipped
over.
3) The platform overload system is used for preventing the operation of machine in case of overload.
Such system is composed of two electric elements, an overload pressure switch and an angle
sensor.
4) The pressure sensor is adjustable, which determines the cylinder pressure and gives feedback to
the platform overload system. When the pressure is excessively high, the pressure switch will
send the signal to ECU and all functions of machine will be stopped until the excessive load is
removed from the platform.
5) The angle sensor in the scissor arm 1 is used for measuring the inclination angle of the scissor
and further determining the platform height.
①
Switch the key switch to the ground controller. Lift the platform to the height about 3.2m from the
ground.
②
Lift the safety prop, move it to the center of the scissor sleeve center and rotate it upward until it is
vertical.
③
Lower the platform height until the safety prop completely contacts the shaft sleeve.
△
! Warning: crush hazard
Be sure to put your hand on correct position of the safety prop when lowering the platform.
④
Open the limit switch base cover on the chassis.
⑤
Remove the limit switch cover.
⑥
Mark and remove two lines of the upper limit switch.
⑦
Make the short connection between the two removed lines.
⑧
Switch the key switch to the two ground controller and draw out the red emergency stop buttons
from the ground and platform controller.
⑨
Slightly raise the platform and recover the safety prop to the installation position.
⑩
Raise the platform to the highest location and continue to press the lifting function selector button.
Result: the alarm is outputted.
Result: no alarm is outputted. Calibrate the platform overload system
6) Lower the platform via the manual lowering function until the platform is folded.
7) Carefully remove the short circuit lines of the upper limit switch.
8) Raise the platform to the highest location and continue to press the lifting function selector button.
