Description of Operation

The DrillMaster is designed to drive a Proportional Flow Control Valve using a PWM output. The valve

controls the flow to 1 to 3 hydraulic motors so it can be used with 1 to 3 section planters. All motors

are in series so they all rotate at the same speed and therefore they all apply the same amount of

seed. Three toggle switches (top of Console) turn the sections off, bypassing a motor, so the RPM of

the remaining motors do not change.

The DrillMaster operates as a “ground speed based controller” using a speed sensor input (from 1 of

the 3 sections) to maintain a target population of seed as ground speed varies. An external Module

is used to multiplex the flow signal so a different section is used when a section is turned off. Going

to Hold, turning all Sections Off, or zero speed will stop auto control and will also stop the PWM Valve

drive if “Auto Shut Off” is turned on (enabled). All sections are automatically turned off if the speed

goes to zero while in Auto mode. Seed flow is measured indirectly by measuring the seed drive shaft

RPM instead of counting seed. Drill Master also provides an early warning when seed bins are nearly

empty by flashing a “FILL” message.

Care and Maintenance of your DrillMaster

Store the console in a cool dry location if it will not be used for an extended period of time, such as

during the off-season. As with any electronic equipment, use care in cleaning so that water or other

liquids do not enter the case.
