7.4.5 ERROR MESSAGE Err-5
The Err-5/Pump C message indicates that the conveyor flow rate is exceeding the target rate and the
control valve is not responding to the console's throttling commands. The alarm will activate within 10 to
15 seconds after the flow rate exceeds 15% of target rate and no valve response is indicated. The Err 5
alarm condition will not shut down the spreader. If the fault cannot be cleared easily by the following
procedures, the field can still be finished with reasonable accuracy by adjusting the speed of the vehicle
to maintain the target conveyor application rate. All other control functions are still operating.
The most likely cause of an Err 5 condition is a faulty hydraulic flow control valve which has stuck in a
partially open position. 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 be-
tween the console and the flow control valve for pinched or broken wires.
If the above checks fail to resolve the difficulty, contact your MID-TECH dealer, or the factory, for addi-
tional help.
7.5 ERROR MESSAGE OFLO, NUMERIC OVERFLOW
The OFLO error message indicates the value to be displayed exceeds the maximum size allowable for
that function. This typically occurs in one of the accumulator positions (Area, Vol. Applied, or Distance
Traveled). This error can be quickly cleared by zeroing the display, using the INC/DEC switch.
7.6 ERROR MESSAGE Err L, LOW VOLTAGE
The message Err L, indicates a low system voltage is being experienced by TASC. Error L will occur
when the console sees power voltages less than 10.0 VDC. First check the positive and negative con-
nections at the vehicle battery. If everything appears all right, check the condition of the vehicle battery
and alternator. There may be a problem with the vehicle’s electrical system.
7.7 ERROR MESSAGES Err C, n, hook (backward 7), INTERNAL DIAGNOSTICS
These error messages may appear from time to time, usually during start up of TASC. A momentary
appearance, followed by no other problems, can be safely ignored. If the messages occur very frequently
during operation, or if they come on and stay on, contact your MID-TECH dealer, or the factory, for further
assistance.
7.8 ERROR MESSAGE Err P, PRINT UNABLE
This message only occurs if you have connected the TASC Control Console to the external printer. It
simply means the printer is asking for data but the console cannot respond until the application function is
complete. This error message is covered in more detail in the printer manual.
