Circuit Breaker (1) - Reset the circuit breaker if a circuit breaker trips. Press the button in order to reset the circuit breaker. If the electrical system is working properly, the button will remain pressed. If the button does not remain pressed or if the circuit breaker trips soon after being reset, check the appropriate electrical circuit. Repair the electrical circuit, if necessary.
Resetting the circuit breakers in a flammable atmosphere or a combustible atmosphere may lead to fire hazards or explosion hazards which may result in personal injury or death. DO NOT reset the circuit breaker when a flammable atmosphere or a combustible atmosphere is present and the power has not been removed from the equipment.
Diesel Particulate Filter (DPF) Lamp (2) - The DPF lamp will illuminate when a regeneration of the DPF is needed. Refer to this Operation and Maintenance Manual, "Diesel Particulate Filter Regeneration" for more information on this lamp.
High Exhaust Temperature Lamp (3) - This lamp is illuminated when a DPF regeneration is active.
Regeneration Disabled (4) - This lamp will be illuminated if the regeneration is manually disabled through the regeneration switch or through the Cat (ET) service tool.
Start Switch (5) - The start switch has three positions: OFF, RUN and START. When the start switch is turned clockwise to the RUN position, the lamps will flash for 5 seconds during the system test. The lamps will then shut off. In the RUN position, the Electronic Control Module (ECM) and electronic systems are powered up.
Diagnostic Lamp (6) - The diagnostic lamp will illuminate when an active fault code is present.
Shutdown Lamp (7) - The shutdown lamp will illuminate when a critical engine event occurs which requires that the engine be shut down. The event should be addressed as quickly as possible.
Shutdown Switch (8) - Use the engine shutdown switch in order to stop the engine. Push the shutdown switch in order to put the switch in the OFF position. Moving the switch to the OFF position will stop the engine. After the engine stops, turn the knob clockwise. Turning the knob will reset the engine shutdown switch to the ON position.
Service Hour Meter (9) - This gauge indicates the total number of clock hours of engine operation. Hours of operation are logged in the ECM. A service tool is needed to retrieve the hours from the ECM. A Service Hour Meter may be installed on the engine.
Idle Speed Switch (10) - When the switch is in the up position, the engine speed increases to HIGH IDLE. When the switch is in the down position, the engine speed decreases to LOW IDLE.
Regeneration Switch (11) - Used to activate a forced regeneration or manually disable regeneration. Refer to this Operation and Maintenance Manual, "Diesel Particulate Filter Regeneration" for more information on this switch.
Illustration 3 g02333673OK to Elevate Idle Switch (12) - Pressing in and locking the "OK to Elevate Idle" switch enables the engine ECM to elevate engine speed automatically when needed. For example, if the engine is running at low idle and a DPF regeneration is activated, having the "OK to Elevate Idle" switch in the LOCKED position will allow the engine speed to increase in order for the DPF regeneration to occur.
