Introduction

Congratulations on purchasing the new MicroGuard® 586 Retrofit System.

This document describes the calibration process for the MicroGuard
assuming that there is no prior knowledge of the geometry of the crane.

This document is designed to assist the calibration personnel in keeping a record of measured
dimensions and test results for review and comparison when subsequent modifications are made to the
capacity chip. This data will provide an on-file record, which may serve future upgrades and changes to
MicroGuard
Recording this important data during the calibration process will ensure a structured and easy to follow
calibration that in turn leads to an accurate and safe calibration.

Preliminary Checks

Before starting calibration, it is important to check the machine geometry. Geometric values may have
been previously entered into the capacity chip from the crane application data sheet filled out by the
crane manufacturer’s engineering department. This data will appear in the relevant boxes, but should
STILL be checked by the calibration personnel.

The following pages provide a list of required measurement checks. Measured values should be entered
in the spaces provided.

Using an accurate tape, measure each dimension shown. It is, at best, a difficult exercise to measure
these dimensions, but still a necessary check. It is recommended that two people carry out this task.
Ensure that clear reference points are used when making measurements.

Boom Hoist Geometry

Dimension “L” is the distance parallel to the boom centerline between the center of the Boom pivot and

the center of the upper Boom Hoist cylinder pivot.

Dimension “J” is the distance at 90 ° to the boom centerline between the center of the Boom pivot and
the center of the upper Boom Hoist cylinder pivot. J is negative when the Boom pivot is above the upper
Boom Hoist cylinder pivot and positive when it is below.

Dimension “G” is the horizontal distance between the center of the Boom pivot and the center of the
lower Boom Hoist cylinder pivot.

Dimension “H” is the vertical distance between the center of the Boom pivot and the center of the lower
Boom Hoist pivot.

It is recommended that the boom is level when measuring dimensions “L” and “J.”
The carrier is assumed to be level for the purposes of measuring dimensions “G” and “H.”

Enter the measured values into each of the gray boxes provided below.

If the Boom pivot is above the Boom Hoist cylinder Upper pivot (as shown), dimension “J” is negative.

Clearly indicate “+” or “-”. The above illustration shows dimension “J” as negative.

Miscellaneous Data

The following checks are for Main Boom Head Sheave Radius and Swing Offset. Swing Offset
is negative when the boom pivot is behind the center of rotation. Measure the circumference of the
boom hoist cylinder rod, which can be done by wrapping a tape around the rod and reading off the value.
Enter the measured values in the gray boxes provided.

Installation Checks

Check wiring and EPROM installations.

•

If swing switches are fitted, perform the digital input monitor routine via the MicroGuard® display

•

to ensure that the switches operate correctly.

• Set the Extension Reel Clutch.

Calibration Routines and Menu Entry

The calibration routines, which are hidden from normal use, require the use of the entry code supplied
with this manual.

To Enter the Calibration Mode:

about 6 seconds. A message requesting a PIN entry should appear. Use the UP and DOWN keys to
enter the PIN, which is 112; calibration entry is complete. If incorrectly entered, the display will return to
the normal working mode.

Once in the calibration mode, the options below are available. Use the UP or DOWN arrow key to display
the desired option. Then, use the SETUP/OK key to enter the routine.

To exit the calibration menu at any time, press the ALARM CANCEL key; this action will return the system
to the normal working screen. After the initial entry of the PIN, the calibration mode can be re-entered at
any time by holding down the ALARM CANCEL and UP arrow keys. No code entry will be required as
long as the power is not reset.

00 - Information - Displays system information and error codes.
01 - Reset Data - Crane data reset to initialize system before calibrating.
02 - Dimensions - Allows entry of crane geometry.
