pump switch is not used, the shorting plug must be installed or TASC will not operate. The optional Ground Speed
Override switch should be mounted conveniently for the operator's use. This switch can be either hand or foot operated.
Check to insure all cables are protected from abrasion and breakage, and secure with cable ties or clamps.
C.5.2. BOOM INTERFACE CABLE
If your sprayer already has switches for controlling the boom valves, you can continue to use those switches. Instead of a
Boom Control Switch box like that described in the previous section, you would use a Boom Status Cable to monitor the
status of the boom valves.
The connector on one end of the Boom Interface Cable plugs into the Boom I/O position on the back of the TASC
Control Console. The other end of the cable has up to nine wires that have been terminated with a female spade terminal.
These wires are individually numbered from one through nine. The installer must decide which of the booms will be
designated number one. Then, each numbered wire from the boom interface cable must be connected to either, the boom
on/off switch or the boom valve itself, in the appropriate sequence. Each wire must be connected to a terminal that is
normally zero volts or open when the boom section valve is closed (OFF) and powered (12 V. DC) when that particular
boom section valve is opened (ON).
The wire ends should be connected first and then routed back to the TASC Control Console. Unused wires should be
taped and secured to prevent damage. Check to insure that the cable is protected from abrasion and breakage, and secure
with cable ties or clamps. Do not run the Boom I/O cable near a two way radio antenna or other source of electrical
noise! Insert the connector into the Boom I/O position on the back of the console (See Appendix A).
The optional Ground Speed Override switch should be mounted conveniently for the operator's use and the excess cable
coiled up and secured in a protected location. This switch can be either hand or foot operated.
C.6. INJECTION PUMP INSTALLATION
The injection pumps supplied with a TASC System are precision peristaltic pumps. If other approved pumps are
installed, the installer should refer to the detailed installation instructions provided with those alternate injection pump-
ing devices. MIDWEST TECHNOLOGIES recommends that the specific installation instructions be attached to this
manual for future reference.
C.6.1. SELECTING THE CORRECT PUMP FOR THE APPLICATION
Use the following formula to determine the required pump capacity for the application. Then check to be sure the TASC
System has been provided with the appropriate pump.
Pump Cap. = Max. Boom Width x Max. Speed x Chemical Rate x (.00202)
(Oz./Min.) (Ft.) (MPH) (Oz./Acre)
Example: A sprayer with 35 ft. booms, traveling at a maximum speed of 7 mph and applying 1 quart of chemical per
acre would require a maximum pump capacity of 15.8 Oz./Min. (i.e. 35 ft. x 7 mph x 32 oz/ac x .00202 = 15.8 Oz./
Min.). Referring to the Pump/Tube Selection Chart in Appendix A we find that a MID-TECH Model-20 pump would be
sufficient for this chemical. However; if you needed to apply 64 oz./ac. of chemical, you would need the MID-TECH
Model-100 pump, (i.e. 35 x 7 x 64 x .00202 = 31.7, which exceeds the capacity of the smaller 20 Oz./Min. pump).
Variations in speed and boom widths will also affect the pump capacity required.
Each Boom Interface also has an Implement Status Connector. For chemical injection to occur, the
status switch must provide (+12 VDC) to the white or green wire. If a status switch is not used, the
shorting plug must be installed, otherwise the TASC System will not operate properly.
