◗ General Information
The Vansco Electronic Monitor is designed for use with
Great Plains Air Drills.
This monitor is packaged in a black anodized aluminum
housing with a mounting bracket. Cables exit from the rear
of the unit. The front panel contains a five digit, seven seg-
ment liquid crystal display, a seven position rotary function
select switch, and three push buttons; ACK/MODE, UP,
and DOWN.
The system is capable of monitoring the following:
•
The RPM speed of the fan shaft
•
Implement ground speed
•
The RPM speed of two meter shafts
•
The status of two bin level sensors. Each bin level sen-
sor is associated with one of the meter shafts
•
Blockage in up to 120 runs using optional modules and
sensors
•
Field and accumulated area that has been worked
Details of operation are provided under the Operating In-
structions in this section on page 13.
A continuous audio alarm will sound upon high fan RPM,
low fan RPM, low meter shaft speed, seed run blockage,
or low bin level. While this alarm is sounding the display
will indicate what fault conditions is present. Pressing the
ACK/MODE button briefly will silence the alarm and the
display will revert to its normal display. Every ten seconds
the display will show all fault conditions that are present.
When the fault condition is removed, the alarm message
will be removed also.
The operator has the ability to set certain parameters of
the monitor’s operation. User variable parameters are:
•
Low fan alarm point
•
High fan alarm point
•
Pulses per revolution of fan
•
Pulses per mile
•
Pulses per revolution of any shaft
•
The width of the Implement
•
English or metric units
•
The number and type of
blockage sensors connected to the unit
The variable parameters, as well as accumulated area are
stored in nonvolatile memory. This means that the infor-
mation will be retained even when power is disconnected.
