3.6 Remote Bar Graph Overview

The REMOTE BAR GRAPH, shown below, displays the percentage of rated capacity of the crane. The

remote bar graph is mounted at the top of the cab front window, in the operator’s line of sight. There are

multiple brightness levels available on the device. The remote bar graph is optional and is not used on
all cranes.

NOTE:

Defective remote bar graphs are not a serviceable item.

FIGURE 3.6 - REMOTE BAR GRAPH

3.6.1

Checking the Remote Bar Graph

The REMOTE BAR GRAPH is very reliable. However, when operated for extended periods, under
extreme conditions, the device may become damaged. The damage is not always apparent. To help
identify subtle faults that are sometimes difficult to find, please review the following comments:

3.6.2

LEDs

The operator may check the LED operation at any time by pressing the test button on the operator’s

display console.

With the System powered, there should always be at least one (GREEN) LED lit. The REMOTE BAR

GRAPH LEDs should ‘track’ or ‘echo’ the bar graph on the operator’s display console at all times.

NOTE:

Always replace the entire bar graph unit if faulty.

3.6.3

Brightness Control

There are four brightness levels. Press the BRIGHTNESS CONTROL BUTTON continuously to

‘cycle’

through the available levels. Release the button at any time to select the desired setting. Or press and
release the button to cycle through the four levels in sequence, one at a time. It is not possible to

‘switch

-

off’ the LEDs using this control.

NOTE:

Set the brightness level when powering up the system. The previous setting is not stored in the

MicroGuard system. The remote bar graph always starts with the LEDs set to maximum brightness.
