5.4.5. ERROR MESSAGE "Err 5"
The "Err 5/Pump L or C" message indicates that the flow rate is exceeding the target rate and the control valve is not
responding to the console's close 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 applicator. If the
fault cannot be cleared easily by the following procedures, the field can still be finished with reasonable accuracy by adjust-
ing the speed of the vehicle to maintain the target application rate. All other monitoring and alarm functions are still operat-
ing.
The most likely cause of an "Err 5" condition is a faulty 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 between 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 additional help.
5.5. 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 (Field Area, Total Area, Total Applied, or Distance). This error can be
quickly cleared by zeroing the display, using the INC/DEC switch.
5.6. ERROR MESSAGE “Err L”, LOW VOLTAGE
The message “Err L”, indicates a low system voltage is being experienced by the control console. Error L will occur when
the console sees power voltages less than 10.0 VDC. First check the positive and negative connections 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.
5.7. ERROR MESSAGES “Err C, n, hook (backward 7)”, INTERNAL DIAGNOSTICS
These error messages may appear from time to time, usually during start-up of the control console. A momentary appear-
ance, 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 dealer, or the factory, for further assistance.
