1.5 BOOM SECTION "ON/OFF" INDICATORS
The boom section on/off indicators show which boom sections have been selected. There is a maximum of nine
boom sections available. When a boom section is selected, its indicator light will light.
1.6 FLOW CONTROL CHANNELS, PRODUCT SWITCHES
Two channels on the TASC are designated as flow control channels only. Both are designed to operate positional
control valves. Channel C is normally used to control the spreader conveyor using a positional hydraulic control
valve. Channel L is normally used to control a liquid application using either a positional flow control valve or a
positional hydraulic control valve. This could be either a wet boom applicator or a liquid impregnation applicator.
Both channels can be preset for a standard rate and an alternate rate. When the switch is turned "ON", its indicator
lamp lights to show the applicator has been selected at its standard rate. When "Alt.-Rate" is selected, the indicator
lamp flashes to indicate a non-standard application rate.
1.7 CHEMICAL APPLICATOR CHANNELS, PRODUCT SWITCHES (TASC 6500 only)
Channels 1, 2, or 3, operating in Peristaltic or Non-Peristaltic modes, require that Channel L or C be ON in order for
them to operate.
Channels 1,2 and 3, are used to control up to three separate chemical applicators. When operating in peristaltic or
non-peristaltic mode, these three channels control the speed of a motor by varying the drive signal to that motor.
Typical installations include the control of liquid injection pumps on a wet boom or granular co-applicators with a
dry conveyor.
When channels 1, 2, or 3 are running in Flow Mode they operate like the L and C channels and can be used to
control a positional control valve.
All three channels can be set for a standard or alternate application rate. When the switch is turned "ON", its indica-
tor lamp lights to show the applicator is selected at its standard rate. When "Alt.-Rate" is selected, the indicator lamp
flashes to indicate a non-standard application.
1.8 BOOM CONTROL SWITCHES
Externally mounted boom control switches are necessary for the proper operation of a TASC system. MIDWEST
TECHNOLOGIES can provide several optional configurations for these switches to meet differing needs. The
console must receive 12 VDC on the boom status line whenever a boom is turned ON.
A boom master switch is a recommended feature. It can be used to turn on or off all selected booms simultaneously.
