7.3 ERROR MESSAGE Err 0, INVALID CONSTANT SET TO ZERO
An Error message Err 0 means one of the necessary constants for calibration, application rates, flow
meter calibration, ground speed sensor calibration or boom width is erroneously set to a zero value.
TASC is therefore unable to resolve a control solution and it indicates an Error. Check the programed
values, looking for those set 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.
A. The message Err 0/Pump ? indicates that a zero value is stored in the calibration number or
application rate for the identified channel. An error message Err 0/ Pump C indicates there is a zero
value in the channel C calibration register. NOTE: an Err 0 on a particular channel (1,2,3 or
L) will not cause a shut down of the other channels but, an Err 0 in channel C calibra-
tion will cause a shut down of TASC until the condition is corrected.
B. The message Err-0/ Dist. Cal. # indicates the distance calibration constant is set at zero, TASC
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.
7.4 ERROR MESSAGE Err-1, 2, 3, 4, & 5, INVALID OPERATION
Any time TASC senses an invalid operating condition, the Console will display an error message indicat-
ing the condition and which channel is associated with this condition. The format of this message is a
continuous audible alarm accompanied by a display designating the Error number (1, 2, 3, 4, or 5) and
the channel number.
7.4.1 ERROR MESSAGE Err-1
The error message Err-1/Pump ? indicates that the system is calling for a higher output than the channel
can supply. An Err-1/Pump C indicates TASC is demanding a higher channel C flow rate than the
applicator can provide. In addition a visual message TOO FAST will flash on the display. Slowing down
will usually clear this error condition.
The console may display an intermittent Err-1/Pump ? message at normal operating speeds. This usually
indicates there is a hard spot in the injection pump tubing which causes the pump to momentarily stall. If
this condition is encountered, carefully inspect the tubing and replace as necessary. The pump must be
calibrated whenever the tubing is replaced.
NOTE: All control channels must have a calibration number other
than zero entered, whether they are being used, or not. If any
calibration number is set to zero, an Err 0 and an audible alarm will
occur, even if that channel switch is not turned ON. The console is
shipped with default calibration numbers in each channel.
