RADIATOR GP 4I7590 - Caterpillar

Note: The MPTS input can only be used on one channel.There is also the option of using an Idle Validation Switch (IVS) on the analog throttle. This switch is used to confirm that the throttle pedal has been physically moved, before reacting to the analog speed demand signal. The IVS and software logic is designed to protect against signal faults which could cause unintended engine speed increases.Programming each throttle input requires some technical knowledge of the throttle specification that is being used. Knowledge is required to program the specifications into the correct ECM parameter values.

Engine Operating Mode Configuration
The engine operating mode configuration feature allows the configuration of up to four separate modes that can be selected via two switch inputs.If only one mode is required, no switch inputs are required and Mode 1 will always be used.If two modes are required, one switch input can be selected to toggle between Mode 1 and Mode 2. If three or four modes are required, two switch inputs will be required. The numbers of switches are selected in the drop-down box at the top of the screen.

Screen 1
Once the number of required modes and switches has been selected, each mode must be configured. Each mode is defined by the following selection:
Mode Number - (1-4)
Switch input 1 and 2 combinations to enable the mode
Enabled - For example, if only three modes are required then mode 4 would be set to "NO". If the switch combination was active for Mode 4, the ECM would display a fault code.
Rating number – This parameter allows any available ratings in the flash file to be selected. The specific rating information can be found in the main configuration screen under "Ratings".
Rated Speed – This parameter is configurable between defined limits in the ECM (for example – 1800 rpm to 2200 rpm).
High Idle – This parameter is configurable between 1800 rpm and 2800 rpm but also limited to 112% of the programmed rated speed.
Throttle Channel 1 Droop Value – This parameter is configurable between 0-10%.
Throttle Channel 2 Droop Value – This parameter is configurable between 0-10%.
TSC1 Droop Value – This parameter is configurable between 0-10%.
Governor Type – This parameter can be configured to "All Speed" governing or "Min Max" governing using the drop-down box.Once the mode configuration has been set, the submit button must be clicked at the bottom of the page. The ECM power must be cycled from off to on.The status of the mode switch inputs can be monitored on the status screen in the electronic service tool.Maintenance Indicator
This feature is configured through the main configuration screen in the electronic service tool.
Illustration 22 g03422642When this feature is installed, the number of maintenance cycle hours can be set. The ECM then counts down these hours and flags an Event code. A J1939 message is sent once the cycle interval reaches 0.This parameter can then be reset via the electronic service tool or over the CAN data link after the
