How to Calibrate the Platform
Overload System
Calibration of the platform overload system is
essential to safe machine operation. Continued
use of an improperly calibrated platform overload
system could result in the system failing to sense
an overloaded platform. The stability of the
machine is compromised and it could tip over.
Note: Perform this procedure with the machine on
a firm, level surface.
1 Level the platform.
2 Determine the maximum platform capacity.
Refer to the machine serial plate.
3 Using a suitable lifting device, place an
appropriate test weight equal to that of the
maximum platform capacity at the center of
the platform floor.
Determine the limit switch trigger point:
4 Gently move the platform up and down by
hand, so it bounces approximately 1 to
2 inches / 2.5 to 5 cm. Allow the platform to
settle.
Result: The overload indicator light and the
alarm is on . Slowly tighten the load spring
adjustment nut by turning it clockwise just until
the overload indicator light and alarm turns
off.
Note: The platform will need to be moved up and
down and allowed to settle between adjustments.
Note: There may be an approximate 2 second
delay before the overload indicator light turns on
and the alarm sounds.
