MA4 APPLICATOR ELECTRONIC CONTROL DISPLAY:
The MA4 Applicator Electronic Control Display is used to control the application rate of the sealant material
that is being applied. System status, spray bar position, material readiness, rate of flow and pump RPM are
all controlled by this computer control panel. Please note; If certain conditions are not met, the function will
be unusable (Gray). Some examples of conditions that are not met are: Spray bar is in stored position,
material is not up to application temp, etc.
ACTIVATED:
Pressing the top left button (#1) on the Applicator Control Panel will switch between
“ACTIVATED” (Green) and “DEACTIVATED” (Red). Once the unit is activated, it will wait until the ground
speed encoding wheel registers a speed to start applying sealant material.
START:
Pressing the second button on the left (#2) will switch between “ START” (Green) and
“STOP” (Red). This is typically turned on and off by using the key fob remote transmitter.
AUTO:
Pressing the third button on the left (#3) will switch from “ AUTO” (Blue) and
“MANUAL” (Yellow). In the auto mode, the unit will control how much sealant material is applied by the
speed wheel as it moves across the ground. In the manual mode, the sealant material application will be
controlled by the pump speed that is set by the application rate.
APPLICATION RATE:
Pressing the top right button (#4) will highlight the “ APPLICATION RATE”
function (Purple) and allow the dial knob to adjust the sealant material application rate. The sealant material
application rate is measured based on a pounds per linear foot measurement. Pressing the button again will
deselect the function (Gray) and the application rate is automatically calculated based on the speed of the
vehicle as reported by the ground speed encoding wheel.
TRIM:
Pressing the second button on the right (#5) will highlight the “ TRIM” function (Purple) and
allow the dial knob to adjust the trim setting. The trim control compensates for a pump that is running slower
due to wear and will speed up the pump a certain % amount. Pressing the button again will deselect the
function (Gray). This feature is only usable while in the auto mode.
