Introduction
Before you attempt the procedures documented in this Special Instruction, make sure that you have read and understand the information in this document.The United States Environmental Protection Agency (US EPA) requires limiting of the engine speed and/or power in certain conditions. This limiting helps ensure proper functioning of the engine emission control system. The EPA allows the temporary disabling of these limits during a qualified emergency situation. Per the US EPA the following conditions qualify for overriding the limitation of power and/or speed.
A significant direct or indirect risk to human life.Below are examples of direct versus indirect risks.Direct - An emission controls condition that inhibits performance of an engine being used to rescue a person from life-threatening situation.Indirect - An emission controls condition that inhibits performance of an engine being used to provide electrical power to a data center that routes 911 emergency response communications.Emission control conditions that limit the engine speed and/or power are not required on engines used in emergency equipment. Per the United States EPA, emergency equipment includes :
Specialized vehicles used to perform aircraft rescue and/or fire-fighting functions at airports, with particular emphasis on saving lives and reducing injuries coincident with aircraft fires following impact, or aircraft ground fires.
Wildland firefighting equipment designed primarily to support wildland fire suppression operations. For example, a bulldozer designed with special features for fighting wildfires would be a piece of emergency equipment.Note: Engines for dedicated non-road emergency equipment are identified by the words, "THIS ENGINE IS FOR INSTALLATION IN EMERGENCY EQUIPMENT ONLY", on the engine emissions label.The information below does not apply to such dedicated non-road emergency equipment engines.The emissions-related derate can be disabled for up to 120 hours of engine operation. The temporary disabling of emissions-related derate is referred to as Operator Inducement Emergency Override and must be reported to the US EPA. The override can only be reset by the engine manufacturer, Caterpillar®. A dealer can reset the override using Caterpillar supplied passwords. Improper use of the override, and failure to report use of the override is prohibited under federal regulations. Such violation is subject to penalties by the US EPA. Civil penalties may be assessed per day operated in violation, and can be severe.Override Overview
To use this feature requires Tier IV Final Prod 5 version of software or greater, and an updated cab electronic display. Check with your Caterpillar® dealer on whether the machine has the latest software and cab display. Displays can differ from one machine to another.This feature can only be enabled using Caterpillar supplied passwords. This feature is disabled by default. This feature will be enabled at the factory if allowed. If the customer wants the feature enabled after delivery of engine, they will need to contact their Caterpillar dealer. Engines going to the European Union or Japan are not allowed to have this feature enabled. For detailed information on activating, deactivating, or resetting the override, contact your Caterpillar dealer. Before you attempt the procedures documented in this special instruction, make sure that you have read and understand the information in this document.When an emergency situation occurs, initial activation of the override is allowed without input from Caterpillar. Prior to activation, the operator will be notified of the following on display : "EMERGENCY USE ONLY. SEE OWNERS MANUAL. PENALTIES APPLY FOR MISUSE." Upon activation, the check engine, and action lamps will also illuminate to alert the operator that the override is active. A code will also become active indicating that the engine emission operator inducement emergency override is active. The override must be paused by the operator if the emergency ends before the 120 hours of override operation has expired. While paused, the equipment will be subject to inducements (derates). For engines in the 0.5 to 18 liter range, the override may only be reactivated if an emergency situation returns prior to reaching an hour threshold of total engine operation since initially activating the override. This threshold is referred to as the backstop timer. This threshold could vary by application, but will typically be 300 hours. For larger engines, there is no backstop timer and override can be reactivated any time until 120 hours of total override activation has been exceeded. After 120 hours of override use, or backstop timer threshold met, the override will expire, and the equipment will be subject to inducements. Upon activation, the check engine and action lamps will continue to be illuminated until the override is reset. If the override has expired, the dealer will need to reset the override in order to use the override again. The code indicating that the engine emission operator inducement emergency override is active, will be cleared when the override is reset. Resetting the override is the only way to clear the code.Enabling the Override
