Drive Control System— Machine Controller LED
Description
15
Drive speed switch on joystick closed (depressed)
16
Drive direction switch on joystick in reverse position
17
Drive direction switch on joystick in forward position
18
NOT USED
19
Ignition switch in “ON/START/RUN” position
20
Signal sent to auxiliary hydraulics flow solenoid (forward direction) -- (Later serial number machines only)
21
Signal sent to auxiliary hydraulics flow solenoid (reverse direction) -- (Later serial number machines only)
22
Signal sent to lift/tilt lock solenoids (lift/tilt activation; all safety requirements met) -- (Later serial number machines only)
23
Reverse direction auxiliary hydraulics joystick button closed (depressed) -- (Later serial number machines only)
24
Seat switch in closed position (operator in seat) -- (Later serial number machines only)
25
Forward direction auxiliary hydraulics joystick button closed (depressed) -- (Later serial number machines only)
26
Signal sent to fuel solenoid to maintain fuel flow
Machine Controller Logic Functions controlled by the machine controller follow specific logic as described in the following table. Numbers in the table refer to the numbered LEDs in the previous table. NOTE: Not all possible logic function states are shown in the table. Function
Glow Plug
“IN” LEDs
“OUT” LEDs
Notes
When the ignition switch is in the (1) -- Ignition switch in "ON" position (10) -- Signal sent to glow plug relay “ON” position and engine temperature is below 50° F (10° C), glow (no LED) Engine temperature is (4) -- Signal sent to glow plug indica- plug and glow plug indicator are below 50° F (10° C) tor on instrument panel activated for a period of time determined by engine temperature (1) -- Ignition switch in "START" position
The engine will start only if:
Later serial number machines: (6) -- Signal sent to engine starter Later serial number machines: (13, 24) -- (24) Seat switch indicates The operator seat is occupied and/ operator in seat and/or (13) parking (11) -- Signal sent to fuel solenoid for or the parking brake is on brake engaged Engine Start 1.5 seconds to start fuel flow Early serial number machines: Earlier serial number machines: (26) -- Signal sent to fuel solenoid to The operator seat platform is down (12, 13, 14) -- (24) ROPS tilt switch maintain fuel flow and/or the parking brake is on and/ indicates operator platform is down or the auxiliary hydraulics lever is in and/or (13) parking brake engaged neutral (centered) position and/or (14) auxiliary hydraulics lever is in forward/reverse position (1) -- Ignition switch in "START" position (16, 17) -- Joystick drive direction Engine Start switch is in (17) forward or (16) Disabled reverse position
Engine will not start if the joystick drive direction switch is not in the neutral position NO "OUT" SIGNALS
Earlier serial number machines: (14) -- Auxiliary hydraulics lever is in forward/reverse position PRINTED IN U.S.A.
169
Early serial number machines: Additionally, engine will not start if auxiliary hydraulics lever is not in neutral (centered) position
