OPERACIÓN TRABA DIFERENCIAL OPERATOR WARNING

1

SYSTEM IS DESIGNED FOR POWERSHIFT DIFFERENTIAL LOCK IN BOTH TRANSMISSION AND AXLE. DIFFERENTIAL LOCK CAN BE MANUALLY ACTIVATED UP TO 3RD GEAR - ALL SPEEDS. WARNING! - CRITERIA FOR 4TH TO 6TH GEAR IS THAT TORQUE THROUGH TRANSMISSION MUST BE BELOW 400Nm. 4TH TO 6TH GEAR CRITERIA IS CONTROLLED VIA THE EST(TRANSMISSION ECU) SYSTEM TRANSMISSION ECU WILL NOT ACTIVATE SIGNAL TO DIFFERENTIAL LOCK IF TORQUE IS GREATER THAN 400Nm.

AUTOMATIC RETARDER OPERATION(SWITCH OFF); APPROACHING AN OVER-SPEED CONDITION, THE TRANSMISSION WILL AUTOMATICALLY UP-SHIFT TO DECREASE ENGINE RPM. WITH THE ACCELERATOR PEDAL RELEASED (OFF GAS), THE RETARDER WILL AUTOMATICALLY APPLY WHEN VEHICLE SPEED REACHES 2000 RPM AND WILL DIS-ENGAGE AT 1850 RPM. THE RETARDER WILL AUTOMATICALLY DIS-ENGAGE WHEN TRANSMISSION OIL TEMPERATURE REACHES 150°C (300°F). VEHICLE SPEED MUST BE REDUCED USING SERVICE BRAKES. WITH THE ACCELERATOR APPLIED (ON GAS), THE RETARDER WILL AUTOMATICALLY APPLY AT 2600 RPM AND DIS-ENGAGE AT 2450 RPM. ABNORMAL OPERATION WILL ACTIVATE TRANSMISSION FAULT CODES THAT WILL BE DISPLAYED AND RECORDED BY THE ECU.
