OPERATION (CONT.)
Console Switches & Buttons (cont.)
SECTION SWITCHES
The system monitors the status of the section switches
to determine whether they are ON or OFF. The
console accumulates area based on the calibrated
section widths. When an individual section is turned
OFF, the respective width is subtracted from the total
width to accumulate area based on the new active
application width. If the rotary switch is in the RATE
position, the numbers 1, 2, or 3 on the display will light
when their respective section is ON.
NOTE: Most RoadMaster™ consoles are equipped
with 3 Section switches. In Lane Mode the
CENTER Section switch is always the PRIMARY
Section and is used to define the "LANE WIDTH".
Ag, Dust or Turf Modes can use any Section
switch. If the operator is only using ONE Section
it must be the Primary Section.
Warning Device
The console is equipped with a RED warning light.
The light will automatically turn ON and flash when the
actual application is plus or minus 10 percent of the
calibrated target rate, or if the TANK alarm feature is
activated and the tank is below the set point (display
will also flash "FILL" message). If the light stays ON
while in AUTO, refer to the troubleshooting section
of this manual. The RED warning light will also be
illuminated when calibration mode is active on the
console.
Audible Alarm
The Audible Alarm is activated for the following
conditions:
1. The Tank Level is below minimum level (TANK
ALARM SET POINT).
2. Float switch is continuously active for 15 seconds
or more.
3. The application Rate Error is greater than 10% for
3 seconds (continuously) after the Auto Delay and
Start Up time have completed and the console
is in AUTO, and the Ground Speed is above the
Alarm Minimum Speed.
Emergency Stop
When in AUTO and in RUN with one or more Sections
ON and the Speed is greater than zero, if the Flow
signal ever stops, the servo will run to fully open. If
Flow remains stopped for 5 seconds or more, it will
automatically reduce the flow to a minimum (run
Servo closed for 4 seconds). "EStOP" will then display
to notify the user of the Emergency Stop. The flow
remains off (or reduced) and AUTO control will remain
disabled until the system goes into HOLD, power is
cycled or CALIBRATE is entered. The Emergency
Stop feature helps protect against "chemical spills" or
over-application if the Flow signal is lost.
NOTE: Volume, Area, DISTANCE & SPEED
counters work in sets, if the VOLUME counter 1 is
reset, it also resets AREA counter 1, DISTANCE
counter 1 and SPEED counter 1. This will be the
same for resetting any counters in the set. Do Not
use the "−" button to select counters because
the button will clear them. (See Resetting System
Counters on page 25). The active set of counters
may be reset to zero independent of other sets of
system counters.
Serial Port
The DB-9 connector on the back of the console
provides access for serial communication. The serial
configuration is RS-232, 9600 baud, in 8-N-1 half-
duplex format. Data is sent and received in comma-
delimited ASCII format. An external device (GPS/
Mapping/AVL System) can change the application
rate on-the-go and also receives and records data
from the RoadMaster.
See Appendix H and I for
data lists available.
