TASC ERROR MESSAGES, COMMON CONDITIONS AND SOLUTIONS
FIRST Check the battery connections, this is the MOST common fault.
ERROR CODE CAUSE REMEDY
If there is flow in the product line but no
flowmeter signals registered.
Pump does not turn at all. Rate sensor is
generating no signals.
Pump runs for 10 to 15 seconds and
stops. Console is receiving no signals
from the rate sensor.
Console senses that the pump is running
when it shouldn't be.
Will shut down system after 5 seconds
of Err 4. If ERR 4 corrects itself, then
system will recover by itself. If ERR 4
doesn't last for 5 seconds, then system
will not be affected.
Carrier application rate has been
exceeding the target rate by 15% for at
least 10-15 sec. Valve is stuck.
Check for air lock in the product pump, causing no
output. Purge pump using the Prime function.
Clear blockage in product strainer.
Check Flow control/Boom connections on the back
of the console. Secure if loose.
Clear blockage of the flowmeter rotor.
Test flowmeter sensor & replace if faulty. See test
procedure in the service manual.
Check channel control connections on the back of the
console. Secure if loose.
Check for power and ground at the pump motor. If
no power, check fuse and battery connection for the
pump driver module. If fuse and battery connections
check ok and there is still no power to the motor,
replace the pump driver module.
Check for obstruction in the pump that may be
keeping it from turning.
Check channel control connections on the back of the
console. Secure if loose.
Pump RPM sensor is faulty. Check sensor wiring,
connections, and mounting location for proper
clearance.
If the pump is actually running when it is not turned
on, unplug the pump power cable at the battery and
call for service help.
If pump is not running, check sensor mounting for
excessive vibration and sensor wire routing to make
sure it is not running near a source electrical pulses
which could cause false rate signals to the console.
Check battery connections.
Verify that the flow control valve is responding.
Check, at the valve connector, for the proper voltages
during the OPEN and CLOSE commands to the
valve. Replace faulty wiring or the valve if necessary.
