3.2 System Self-Test
The system will perform a Self-Test when the power is turned on or when the
TEST
button is pressed
during operation. This will verify the computer, display console, cables, and all remote sensors are
working properly.
During the Self-Test all display functions are activated, allowing the operator to ensure all display
indicators are functional. The Self-Test lasts approximately 6 seconds.
NOTE: It is important the indications shown during the Self-Test are recognized and understood by the
operator. This will aid in correctly determining computer and display communication problems
.
After the system is powered up, or after pressing the
TEST
button (T), the display will show the
following indications:
•
All display segments of the bar graph display (B) will be black (ON).
•
All display segments of the load, angle, radius, length, and rated capacity windows will be black
(ON), showing “188.8” or “888,800” for load and capacity.
•
All green configuration lamps will be illuminated.
•
The red LED indicators for overload and Anti-Two-Block will be illuminated.
•
The yellow LED indicator for pre-warning will be illuminated.
•
The audible alarm will sound in the crane cab.
•
The display will now show the crane model/chart number and the units of measurement along with
the message: “SYSTEM SELF-TEST IN PROGRESS.”
