Coolant Level Sensor (If supplied by Vehicle Manufacturer)
Determines if the System monitors the coolant level sensor input.* Enabled (As shipped by Caterpillar)* Disabled (Programmable)The engine functions that are monitored have the following parameters. If there is a coolant loss signal, there will be a 10 second delay to verify the condition, then the system will derate the engine for 40 seconds before shutdown.If there is low oil pressure or coolant temperature signal, there will be a 2 second delay to verify the condition, then the system will derate the engine for 30 seconds before shutdown.Customer Specified Parameters
The Electronic system is capable of being programmed for several customer specified parameters. These parameters are generally programmed so the vehicle will achieve optimum fuel efficiency and operator convenience.Customer Specified Parameters allow the owner/customer to limit how a driver operates the vehicle. The parameters may be changed as often as needed to conform to the customers' operation or as new drivers are assigned to a particular truck. The customer specified parameters require Customer Passwords to change the parameters.Some parameters may affect engine operation and lead to driver complaints about power or performance, even though the engine is performing to specification. For detailed instructions on how to program the 3406C Electronic for optimum performance and fuel economy, refer to Specing for Peak Performance, LEKT8467.The engine includes the features of programmable low idle and top engine limiting (TEL). Cruise control, PTO governing, vehicle speed limiting, (progressive shift control), retarder coast/latch and idle shutdown timer are also available depending on OEM truck configurations. Low idle and top engine rpm limits are customer programmable to promote maximum fuel efficiency. The 3406C Electronic system allows the owner to select power ratings within a "family" to more efficiently match the vehicle to the application. The Customer Specified Parameters available and a brief explanation of each follows. Engine Rating Number- Number of rating within horsepower family. The Personality Module defines the horsepower family and may contain several ratings within that family. The rating number defines which rating is used within that family. Several power ratings can be selected depending on the horsepower (kW) family of the engine. Vehicle Identification Number- The owner's description, or unit number of the vehicle. (Only for customer reference; not required by ECM.) PTO Mode Speed Limit (PTO)- Maximum vehicle speed at which the PTO Governor will function (between 0 and 15 mph [0 and 24 km/h]). If vehicle speed signal exceeds the programmed value, the control will exit the PTO Mode. PTO Mode RPM Limit (PTO RPM)- Maximum engine rpm attainable in the PTO Mode. The rpm limits are between 600 and 3000 rpm. PTO Engine Speed Ramp Rate- Engine rpm (speed) rate of increase. This parameter determines ACCEL, DECEL and RESUME PTO Engine rates of increase/decrease. The programmable limits are between 50 rpm/second and 500 rpm/second. Low Gears #1 RPM Limit (LoGr #1)- Engine speed is limited below Low Gear #1 Turn Off Speed. The engine will hesitate at this speed then allow
