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.

Result:

The overload indicator light and

alarm is off

. Slowly loosen the load spring

adjustment nut by turning it counterclockwise

just until the overload indicator light and alarm

turn on.

Note: There may be an approximate 2 second

delay before the overload indicator light turns on

and the alarm sounds.
Note: The platform will need to be moved up and

down and allowed to settle between adjustments.

Confirm the setting:

5 Turn the key switch to platform control.
6 Lift the test weight off the platform floor using

a suitable lifting device.

7 Place the test weight back onto the center of

the platform floor using a suitable lifting

device.

Result: The alarm should be off. The platform

overload indicator light should be off at both

the ground and platform controls.

Note: There may be an approximate 2 second

delay before the overload indicator light and alarm

turn off.
8 Add an additional 10 lb / 4.5 kg test weight to

the original test weight to overload the

platform.

Result: The alarm should sound. The platform

overload indicator light should be flashing at

both the ground and platform controls.

Note: There may be an approximate 2 second

delay before the overload indicator light turns on

and the alarm sounds.
9 Test all machine functions from the platform

controls.

Result: All platform control functions should

not operate.

10 Turn the key switch to ground control.
11 Test all machine functions from the ground

controls.

Result: All ground control functions should not

operate.

Note: If the platform overload system is not

operating properly, repeat steps 1 through 4.
