HARDI MT-9000 OPERATOR’S MANUAL
20 Pin Module Connector Troubleshooting:
To test outputs at 20 pin connector, use a voltmeter (VM). Set the
meter to read voltage and voltage scale to 20 volts or greater. Insert
negative lead into A side of 20 position connector at Sprayer Control
Module. Insert positive lead into B side of connector. For section valve
output, Main On/Off Valve or Pressure Regulating Valve in question.
To test section valve outputs, place the Master switch in Man and toggle
the section switch on. The VM should read approxi12V,
toggling the section switch off the VM should read approximately -12V.
If section valve output tests good but valve does not operate, check for
broken connection between connector and valve. If section test fails,
be sure to check number of sections setting in System Cal.
To test the MAIN ON/OFF valve, place the master switch in MAN, the
VM should read approxi12, with the master switch in HOLD the
VM should read -12V. If MAIN ON/OFF valve output test checks is
good - but valve does not operate,check for broken connection
between connector and valve.
To test the pressure regulating valve output, place the switch in MAN.
While holding the adjust switch in the "+" position, the VM should read
-12V. While holding the adjust switch in the "-" position, the VM should
read =+12V.
If nEg was selected in System Cal under rEgP, then voltage test will be
opposite of aforementioned. If pressure regulating valve output tests
good but the valve does not operate, check for broken connection
between connector and valve.
