Trouble shooting of the MIDWEST TECHNOLOGIES TASC System begins when the TASC Control
Console senses a problem or inconsistency in the system. When this happens, TASC alerts the operator
by signaling a visible and audible alarm.
7.1 ERROR MESSAGE Err, INVALID SET-UP PROCEDURE
TASC 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. If the Display Selector is turned to the L & CHEMICALS, VOL. APPLIED or APPL. RATE position
and either; no channel 1,2,3 or L rate switches are turned ON or, more than one of these rate
switches are turned ON. This ensures the appropriate calibration number, density, or application rate
value is displayed.
B. When the Display Selector is in the WIDTH position and more than one boom switch is turned
ON. Only one boom section width can be entered at a time.
C. When the Display Selector is in the SCAN position.
7.2 ERROR MESSAGE Err E, INVALID MEMORY
TASC stores all critical SET-UP values in two separate internal memory locations and periodically com-
pares 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 enter 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.
