Seventh screen:
Pulses/Gallon Adjust
309
This screen allows for changing the number of pulses
per gallon being fed to the computer. This number
should be set to 309 for a 42 Series pump and 331 or
309 for a 90 Series pump, depending on which motor
is used. Use the application rate switch to set this num-
ber.
Eighth screen:
Threshold Adjust
16
This screen allows for adjusting the target current
for the start of spraying. This number can be adjusted
up or down. A higher number will give a more aggres-
sive start when the master spray switch is turned on. A
lower number will give a more gentle start. The num-
ber on each distributor needs to be set to match the cur-
rent in milliamps that is required to just start the as-
phalt pump turning. Refer to engineering instruction
#9100411 or the service video for detailed instructions
on how to find the right value for the threshold.
Ninth screen:
4.39 to 1 Ratio
This can be changed using the application rate switch
to use this computer with earlier model distributors,
however for all Centennial II models this must be set to
4.39. On a BTS computer, this screen does not appear.
Tenth screen:
Relay Time Delay
0.2
Sets the spray delay to allow for the 4-way valve to
be moved before opening the spray nozzle valves. The
spray delay should be set to 0.2 seconds using the ap-
plication rate switch.
Eleventh screen:
EXIT=PUSH APP INC
SAVE=PUSH APP DECR
This screen allows you to return to the operating
mode, or saving the setting and returning to the operat-
ing mode. Push down and hold the application rate
