Refer to Figure 12
The cab console is informing you the length of
time that the drive will be operating, in order to
meter the amount of seed you have requested, at
the calibration number, drill width, and number of
rows you have selected.
Refer to Figure 13
If the screen reads TIME TOO LOW, or TIME TOO
HIGH, you will need to increase the amount of
seed that you will count or measure. For calibra-
tion accuracy, the controller firmware will not allow
you to calibrate at settings that would result in the
drive rotating for less than 4 seconds, or more
than 255 seconds. Press the Function key to ad-
vance to the next window.
Refer to Figure 14
The drive is about to operate, meaning there is a dan-
ger of entanglement if anyone is in the drive area. Be
sure to verify that no one is near the drive area before
advancing to the next step.
Set the three position toggle switch on the Electric
Clutch control box to the “CAL” position. This over-
rides the cam switch located on the rockshaft
allowing the drives to operate while the drill is in
the up position.
Refer to Figure 15
Only after you have verified the drive area is clear,
press the Up arrow key to initiate calibration
mode. If drive area isn’t clear, press Down arrow
key to exit calibration mode.
