1. Auxiliary load valve assembly
Note: Hydraulic AUX switch functionality is dependant on attachment
configuration.
The hydraulic AUX switch is a normally open ball switch that is held closed while
the joystick is in the neutral position (N.O.H.C.). The switch is located in the
joystick assembly of the auxiliary load valve. While hydraulic flow to attachments
is controlled mechanically by moving the joystick, the machine can be configured
through the InfoCenter to use joystick movement (via the hydraulic AUX switch)
to control the electrical demands of an attachment.
The T1: TEC monitors the position of the hydraulic AUX switch. Signals from
the hydraulic AUX switch can be used by the T1: TEC to control ground speed
and engine speed.
The hydraulic AUX switch and its circuit wiring can be tested as a T1: TEC
input using the InfoCenter Display; refer to
Troubleshooting (page
wiring are not functioning correctly, proceed with the following test procedure:
1. Remove the operator's console; refer to
Operator's Console (page
2. Disconnect the wire harness connector from the switch.
3. Check the continuity of the switch by connecting a multimeter (ohms setting)
across the switch terminals.
4. When the joystick is in the neutral position there should be continuity (zero
ohms resistance) between the switch terminals.
5. When the joystick is any of the forward or rearward positions there should be
no continuity (infinite ohms resistance) between the switch terminals.
