The Err-3/Pump C message indicates TASC is not receiving a signal from the channel C (conveyor) rate
sensor. This could indicate a major problem, stop the vehicle, turn off all boom sections and look for the
following possible faults.
A. The hydraulic flow control valve fails to open. Check for power, ground, and correct polarity. If
there is no power at the flow control valve, check the in-line fuse near the positive battery connection.
Also inspect the wiring harness from the valve to the battery. If there is power, ground and correct
polarity, check the signal cable between the console and the flow control valve for pinched or broken
wires.
B. If the conveyor is turning, but TASC is not recognizing it, the most likely cause is the wiring
between the rate sensor and the TASC Control Console. Carefully check the integrity of the wiring .
C. If the above checks are made and the system still doesn’t respond, contact your MID-TECH
dealer, or the factory, for additional help.
7.4.4 ERROR MESSAGE Err-4
The Err-4/Pump ? (1,2,3 or L) message indicates the channel is applying when it should be OFF or it is
applying faster than TASC requires and it cannot be controlled. If this condition persists for more than 5
seconds, it is an indication of a faulty control module. (Call your MID-TECH dealer for assistance.)
CAUTION: THIS IS A MAJOR FAULT CONDITION. THE ALARM WILL
CONTINUE TO SOUND UNTIL THE ERROR CONDITION IS CLEARED.
STOP IMMEDIATELY AND SHUT THE SPRAYER OFF. CHECK ALL
CHANNELS, DISCONNECT ALL ERRANT CHANNELS AT THE POWER
CABLE CONNECTION. THIS WILL REMOVE POWER TO THE DRIVE
AND STOP THE CHANNEL.
NOTE: Error 3 requires all booms OFF, status switch
OFF, or zero groundspeed in order to clear.
