5.0. TROUBLE SHOOTING THE ARC SYSTEM
Trouble shooting of the MIDWEST TECHNOLOGIES control system begins when the control console senses a problem or
inconsistency in the system. When this happens, the control console alerts the operator by signaling a visual and audible alarm.
5.1. ERROR MESSAGE “Err.”, INVALID SETUP PROCEDURE
The control console will display an “Err.” error message when the switch settings on the console are not compatible. If you
encounter the “Err.” message, check the switches to be sure you have the proper combination for the operation you are trying to
perform. The “Err.” message will clear once the proper switch combinations are selected. When the console is in the SET- UP
mode, the following switch combinations will cause the “Err.” message to be displayed:
A. When the Display Selector is in the IMPL. WIDTH position and more than one Boom switch is turned ON. Only one
boom section width can be entered at a time.
B. When the Display Selector is in the TOTAL AREA position. There is no function in this condition.
C. When the Display Selector is in the SCAN position. There is no function in this condition.
D. When the Display Selector is in the APPLICATION RATE position. (STnrd or rEFLO mode)
5.2. ERROR MESSAGE “Err E”, INVALID MEMORY
The control console stores all critical SET-UP values in two separate internal memory locations and periodically compares the
two sets of values. If the two values do not match, the console automatically shuts down all control functions and displays the
“Err E” message in the OPERATE mode.
This feature prevents application errors in the unlikely event that electrical interference or a power surge has disrupted the
information used by the console. If the “Err E” message appears, hold the INC/DEC switch down until the alarm quits
(approximately 5 seconds). This resets all errant values to zero (“0”). Now check all programed values, looking for those reset
to zero, and reenter the correct values as needed. For this reason, MIDWEST TECHNOLOGIES strongly recommends recording
your current calibration numbers in a convenient location.
NOTE: Check all values, this type of error usually involves more than one position.
5.3. ERROR MESSAGE “Err 0”, INVALID CONSTANT SET TO ZERO
An "Err 0" message means one of the necessary constants for flow calibration, ground speed sensor calibration or boom width
is erroneously set to a zero value. The control console is therefore unable to resolve a control solution and it indicates an Error.
Check the programed values, looking for those set to zero, and reenter the correct values as needed. For this reason, MIDWEST
TECHNOLOGIES strongly recommends recording your current calibration numbers in a convenient location.
A. The message “Err 0/Pump L or C” indicates that a zero value is stored in the rate calibration number. An “Err 0” in the
flowmeter or rate sensor calibration will cause a shut down of the application vehicle until the condition is corrected.
(Pump L is indicated when the console is set to liquid operation and Pump C is indicated when the console is set to
granular operation.)
B. The message “Err-0/ Dist. Cal. #” indicates the distance calibration constant is set at zero, the sprayer will be shut down
until this condition is corrected.
C. The message “Err-0/Boom #” indicates the width for the boom section selected has been set to zero.
