D.2.5. HANDGUN MODE, MANUAL VALVE OVERRIDE:
The flow control valve can be set to a manual override condition, if needed. Put the TASC console in "SET-UP" mode,
with the display selector on "Carrier, Application Rate". Use the INC/DEC switch to set the application rate to 0.0
gallons/minute. When the mode selector is switched back to "OPERATE", the display will show "Flow Contl OFF
Auto, Handgun", and the flow control valve is driven fully open.
When in the Manual override condition, and with the display selector in "Carrier, Application Rate", the flow control
valve responds only to operation of the INC/DEC switch on the console. Flow can be controlled, either by the INC/DEC
switch setting, or by feathering the handgun trigger. When flow is established with the handgun valve, the console will
display flow as GAL/MIN. Any injection pumps selected "ON" will be controlled to the proper rate per hundred gallons,
based on the actual flow rates measured by the flow meter.
OPERATING WITHOUT A FLOWMETER: Manual Override Mode will also allow handgun operation without a
flowmeter. Refer to a tip chart to find the pressure required by your handgun tip for the flow rate desired. After putting
the console into Manual Mode, as described above, use the INC/DEC switch and a pressure gauge to set the desired
pressure. Rotate to "TEST SPEED" and set the desired flow rate in gallons per minute (same flow rate used to select
operating pressure) with the INC/DEC switch. Operation will be the same as above except that any active injection
pumps will be controlled according to the rate set into the TEST SPEED position.
D.2.6. HANDGUN MODE, ERROR MESSAGES
(See also section 8.0 in the TASC Manual)
Error-1: "Error - 1, Pump #" The indicated pump is running at its maximum rate. An Error-1 condition lasting more
than 5 seconds will cause all the injection pumps to stop and the flow control valve to close, stopping all spraying
operations. Check power connections and programming. Verify that the pump is large enough for the desired flow
rate. Once the problem is corrected, Error-1, Pump # is cleared by first selecting Normal and then returning to the
Handgun mode on the switch panel.
Error-3: "Error - 3, Pump #" No sensor pulses are being received from the indicated pump. An Error-3 condition lasting
more than 5 seconds will cause all the injection pumps to stop and the flow control valve to close, stopping all
spraying operations. Check power, ground and fuses on the pump power cable. Check the programming. Check if the
pumps runs before the error condition occurs. Once the problem is corrected, Error-3, Pump # is cleared by first
selecting Normal and then returning to the Handgun mode on the switch panel.
Error-4: "Error - 4, Pump #" The indicated injection pump is running when it should be off. An Error-4 condition will
immediately cause all the injection pumps to stop and the flow control valve to close, stopping all spraying opera-
tions. Check for normal operation of the injection pump, the pump driver module may need to be replaced. Once the
problem is corrected, Error-4, Pump # is cleared by first selecting Normal and then returning to the Handgun mode on
the switch panel.
Error-5: "Error -5. Pump F" The carrier flow rate is exceeding the target rate and the flow control valve is not respond-
ing to the consoles commands. An Error-5 condition lasting more than 5 seconds will cause all the injection pumps to
stop and the flow control valve to close, stopping all spraying operations. Check the fuse and power and ground to the
flow control valve. Check for a stuck valve. Once the problem is corrected, Error-5 is cleared by first selecting
Normal and then returning to the Handgun mode on the switch panel.
