1 INTRODUCTION

1.1 Module pin types

DI (Digital input):
DI pins have 2 logical states, 0 (off) and 1 (on). Module digital inputs are for instance
used to read operator activities. When the operator presses the horn button, module
DI Horn XC1.21 changes state from 0 to 1.

AI (Analog input):
Analog inputs are used to read values from all kinds of sensors, for instance
hydraulic oil temperature sensor is connected to AI pin (XM2.12).

DO (Digital output):
DO pins have 2 logical states, 0 (off) and 1 (on). Module digital outputs are used to
control machine devices. When the operator has pressed the horn button module
DO horn XM1.15 changes state from 0 to 1. This generates sound signal from the
horn device.

PWM (Pulse width modulation):

PWM outputs are used to control proportional valves, for instance boom up valve
XF1.3.

1.2 The naming of module connectors

The following names are used throughout the whole document.

• XC1 – Chair module, connector 1

• XC2 – Chair module, connector 2
• XD1 – Dashboard (or shortly Dash) module, connector 1
• XD2 – Dashboard (or shortly Dash) module, connector 2
• XF1 – Front module, connector 1
• XF2 – Front module, connector 2
• XM1 – Middle module, connector 1
• XM2 – Middle module, connector 2
• XR1 – Rear module, connector 1
• XR2 – Rear module, connector 2

1.3 Machine function modes

Manual mode: All machines’ control devices are controlled by the driver in the
machine cabin.

RRC mode: There is no driver in the machine cabin. The machine is controlled
remotely by radio remote controller (RRC).

Automine mode: - There is no driver in the machine cabin. The machine is

controlled remotely by an operator in an automine control room.

 Output Preconditions
LHD Upgrade Page 11 / 60

STEP 0:
Initial conditions and initialization:
- Is ride control option parameter PAR_Option_RideControlInMachine (0 as
default) activated.
- Are the following conditions true: Enable, Emergency stop circuit, engine
running.
- Is ride control activated from the button.

Speed and gear parameters:

- Does machine speed exceed PAR_RideControlStartingSpeedLimit (20 as
default).
- Is current gear >= PAR_RideControlStartingGearLimit (1 as default).
- How many accumulators PAR_HowManyPhase parameter (1 as default).

STEP 1:
Boom and pump control:
- Lifting the boom with full power.

Monitoring the boom lifting:

- Monitoring the boom lower limit switch. Stop lifting after the lower limit
switch deactivates. The limit switch has 100ms delay filtering.

STEP 2:
Boom pressure weighing:
- Take 100 samples from the boom pressure (1s).

STEP 3:
 Output Preconditions
LHD Upgrade Page 12 / 60

Pressure accumulator 1 function:

- If the STEP 2 measured pressure is less than
PAR_BoomPressureBucketFullLimit (100bars as default), open an
accumulator 1 and the tank valve.
- After the valve is opened wait for 500ms.

STEP 4:
Pressure accumulator 2 function:
- If the STEP 2 measured pressure is equal to or greater than
PAR_BoomPressureBucketFullLimit (100bars as default), open an

monitored. If the bucket is being controlled, the accumulator and tank valve
is closed for the bucket controlling time. The accumulator and tank valve
are opened again once the bucket control is finished.
