The DPLCM uses the readings from the load cell to
regulate the air valves to increase or decrease
pressure in the air cylinders.
Air Compressor
The 12VDC air compressor requires both an
electrical connection and a mounting location.
Mount the compressor:

as close to the tractor battery as possible using the
least amount of electrical connections as possible to
minimize voltage drop,

on the tractor or planter where most convenient, and

where cool, clean air can get to it.
The battery connection is equipped with one
large 60 amp spade fuse (automotive type).
If your tractor has an on-board engine
driven compressor capable of 150 psi, it can
be used instead of the one supplied with the
planter. Hook the on-board compressor to
the air tank with line provided.
Place the air filter in the tractor cab where it can pull
clean air from the cab. The remote air filter line
should be as short as possible.
Air Tank
A horizontally mounted air tank is provided and
mounted on the wing.
Open the air tank petcock (12) once daily to drain
water accumulation.
The system is designed to run at 150 psi (1034 kPa).
When the pressure drops to 135 psi (930 kPa), the
compressor engages and builds back up to 150 psi
(1034 kPa). Duty cycle varies based on air usage.
Air Tank Lines
The air tank has two lines. A 3/8 inch line (13) attaches
the compressor (14) to the air tank (15). A 1/4 inch (16)
splits at a “T” junction (17) and goes to the valves (18).
The other end attaches to the compressor plate (19)
where it activates the pressure switches.
If an on-board compressor is used, plug or
bypass the pressure switch branch.
Before going to the field, check for air leaks:
1. Turn the compressor on to pressure up the
primary system until it automatically shuts off. If
the system loses pressure, check for leaks.
