CAT Secondary Data Link
The CAT Secondary Data Link provides the ability for each ECM to have a CAT Data Link that is local to that engine. This feature also enables a global CAT Data Link to connect to other engine controls through a common data link. This enables the operator to communicate through a single Customer Communication Module (CCM) or through a telephone line with all of the engines that are in an engine room.The CAT Secondary Data Link provides the capability for as many as eight generator set engines to communicate via a remote display or a control panel. The CAT Secondary Data Link is for use with the following systems: switchgear, remote monitoring and control systems.Switching between data links requires the use of the Cat ET software. Refer to Systems Operation, Troubleshooting, Testing and Adjusting, RENR7902, "Electronic Modular Control Panel 3 (EMCP 3)" for more information.Ether Injection System
Note: This is an optional feature.The ECM automatically injects ether into the air inlet manifold when the following conditions are met:
The engine rpm is between 50 and 400 rpm.
The jacket water coolant temperature is less than 21 °C (70 °F).The duration of ether injection varies linearly with the jacket water coolant temperature. The duration of ether injection varies within the following range:
15 seconds at the maximum temperature of 21 °C (70 °F)
130 seconds at the minimum temperature of −40 °C (−40 °F)The longest duration of ether injection is 130 seconds even if the jacket water coolant temperature is less than −40 °C (−40 °F). A switch enables the operator to inject ether manually. This can occur when the following conditions are met:
The switch for ether injection is in the manual position.
The engine rpm is more than 50 rpm.
The jacket water coolant temperature is less than 21 °C (70 °F).Air Shutoff
Note: This is an optional feature.The air shutoff uses a plate that rotates on a shaft in order to shut off inlet air to the aftercooler. The engine stops because of the restricted air supply to the combustion chamber. The air shutoff only actuates for the following conditions:
The Emergency Stop button is pressed.
An overspeed shutdown occurs.Cold Cylinder Cutout
Note: This is an optional feature.The Cold Cylinder Cutout strategy is used so that the ECM may perform the following functions:
Reduce the white smoke for cold starting.
Minimize the duration of advanced timing (cold mode).
Reduce the use of ether injection.The ECM automatically turns off one electronic unit injector at a time during the following occurrences:
Cold start-up
Extended time at low idleThe ECM monitors the change of the fuel rack in order to determine if a cylinder is firing. If the cylinder is firing the ECM activates the electronic unit injector. If the cylinder is not firing the electronic unit injector remains deactivated. This reduces white smoke.The following conditions must be met in order to activate the Cold Cylinder Cutout strategy:
The Cold Cylinder Cutout parameter is programmed to "ENABLE".
The engine rpm is equal to high idle rpm or less than high idle rpm.
The fuel rack is
