Note: Ensure Pitch Mode Switch is in Manual position during Calibration.

RED Fault Lamp Condition:1. Fault in Foot pedal Sensor2. Red Stop Lamp signal detected via CAN-Bus from engine

Fault Indicator Lamps are direct output from MCU

AMBER WARNING Lamp Condition:1.Amber warning detected via CAN-Bus from engine; Ex. Low Oil Pressure2.Malfunction Indicator Lamp via CAN-Bus from engine.3. Protect Lamp signal detected via CAN-Bus from engine.4. With key on an Amber lamp will show fault if the hydraulic temp sensor doesnot read a valid temp in 30 seconds.5. Fault detected in Left Pitch position sensor.6. Fault detected in Right Pitch position sensor.7. Fault detected in Stroke Position sensor.

LED Warning Indicators

D6i Notes1. At KEY ON position; all indicator lamps, cooler fan, fuel pump andengine Gov actuator and EGR will come on for 10 sec. Batterycharge fail lamp will remain on after if engine not running.2. To check FPS command signal, with unit in CSM, move FPS andlisten for the pitch dump valve to deactivate.

Temp Sensor P/N 22746 - For monitoring hydro fluid temp. Allows MCU to determine if cooler fanshould be ON or OFF and for CSM. SW version 102 and higher allows the hydraulic temp tobe read on the WST down to 21 degrees F

Stroke Valve CircuitDiagnostics Screen - View pump stroke value in the field. This field is showing the current“feedback” on the stroke circuit in .1 Ma.

The measurements below should be expected in each case:1. Read around zero or even Neg with the seat switch open.2. Read around 1500 when seat switch closed but NO pump stroke command<off foot pedal>.3 Read around 3000 or 3A when a pump stroke command is sent to the stroke valve.

If it reads ZERO all the time, check the coil resistance, seat switch and complete circuit from PIN41 at MCU and thru the ground at fuse distribution block.

Relay Part NumbersEngine Main/Accumulator 32096Engine Starter/Preheat. 32094Cooler Fan/Lights. 12017

Foot Pedal Sensor - Sends command inputsignal to MCU to drive stroke valve/strokecylinder.Requires Calibration. Preset to 20% +/-5

Stroke Sensor - contained within the strokecylinder. Requires calibration on new set up andafter Max blade speed has been adj or ZeroStroke reset.
