Hydraulic Down Force
Alarm Explanation and Resolution
Down Force Inadequate
Problem: System is at maximum hydraulic pressure, but does not achieve an acceptable gauge
wheel load. Often times this alarm occurs when down force actuators are lifting the planter tool
bar.
Resolution: Add weight to planter. If planter tool bar is not lifting, increase maximum down force set-
ting in configuration setup.
Hydraulic Pressure too low
Problem: Hydraulic pressure is at 0 and the system is demanding more pressure.
Resolution: Check hydraulic hoses for proper connections. Ensure SCV remote is set for continuous
flow. Zero each channel’s pressure sensor only when mechanical gauge reads 0 psi.
Low Gauge Wheel Load
Problem: Down force system is not achieving an acceptable gauge wheel load.
Resolution: Increase aggressiveness for problematic channel under settings button from run screen.
This alarm may be followed by Down Force Inadequate, in which case consult that alarm resolu-
tion section.
Pressure Sensor Failure
Problem: Pressure sensor is outside voltage range.
Resolution: swap cables with other channel (if applicable), re-zero pressure sensors. If problem
persists on same channel, replace pressure sensor. If problem is now on other channel, inspect/
replace cable.
Row Module Communication Lost
Problem: Row module communication lost.
Resolution: Inspect cabling of row module. Replace row module.
Row Module Failure
Problem: Row module is not sensing inputs. Row module is power cycling at intervals of less than 2
seconds
Resolution: Swap module with different row. If problem follows, replace module. If problem exists on
same row, inspect or replace load sensor.
# Row Modules does match the display configuration
Problem: Configuration was set to a number of sensors that was not detected by the system.
Resolution: Create a configuration that matches the number of sensors used. Check that all row
modules are communicating. Flashing green LED on the row module indicates proper communi-
cation.
