Operation
Main Circuit Breaker
See Figure 3-10. The main circuit breaker is located on
the main control panel. When the breaker is OFF (O),
power is interrupted to the connection lugs, the optional
cam lock receptacles, and the generator. The breaker
may be switched ON (I) once the connections have been
made to the connection lugs or the optional cam lock
receptacles, and the unit has been started and allowed to
reach normal operating temperature.
Figure 3-10. Main Circuit Breaker
Reasons the main circuit breaker may trip:
• Overload of the generator circuits to the connection
lugs or the optional cam lock receptacles.
• The door covering the connection lugs or the
optional cam lock receptacles is opened.
• If the emergency stop switch is activated.
Verify any problems that cause the main circuit breaker
to trip are corrected before returning the switch to ON (I).
NOTE: The main circuit breaker only interrupts power to
the connection lugs and the optional cam lock
receptacles. The customer convenience receptacles
have power even if the main circuit breaker is OFF (O).
Use the individual circuit breakers located near each
receptacle to disconnect power to these receptacles.
DOC and SCR Cleaning
Operations
When enabled, the exhaust after-treatment system goes
through an automatic cleaning process known as
regeneration. Under normal circumstances, regeneration
occurs without interrupting the unit operation and with
minimal operator involvement. In the event there are
conditions requiring the operation of the unit with the auto
exhaust after-treatment cleaning disabled, the operator
may be required to perform procedures to enable or
disable the auto exhaust after-treatment cleaning. The
operator may also be required to perform a manual
regeneration.
NOTE: Always park the unit in a safe location for
elevated exhaust temperatures and check for adequate
fuel level before beginning the exhaust after-treatment
cleaning process. The cleaning cycle can take an
extended period of time (approximately 45 minutes).
Cleaning is complete when the regeneration indicator
remains off.
Disabling Automatic (AUTO) Exhaust After-
Treatment Cleaning
The auto exhaust after-treatment cleaning feature should
always be enabled unless doing so would cause an
unsafe working environment. In the event that an unsafe
working environment occurs, proceed as follows to
disable the auto exhaust after-treatment cleaning feature:
1. Open the control door and locate the switch
labeled REGEN INHIBIT.
2. Set the switch to DISABLED (O).
3. Enter the SCR status screen and verify the
disabled regeneration indicator appears above the
words SCR INHIB - SOLID. See Selective
Catalytic Reduction (SCR) Monitoring.
NOTE: Disabling auto exhaust after-treatment cleaning
is not recommended for any situation unless it is safety
related or if the fuel tank lacks the required fuel to
complete the cleaning process.
Force a Manual Exhaust After-Treatment
Cleaning
If running the unit with the exhaust after-treatment
cleaning function disabled, the SCR status screen may
display a red alarm, prompting the operator to force a
manual exhaust after-treatment cleaning. Proceed as
follows to force a manual exhaust after-treatment
cleaning:
1. Open the control door and locate the switch
labeled REGEN INHIBIT.
2. Set and hold the switch in ON/FORCED (I) for five
seconds.
3. Enter the SCR status screen and verify the
regeneration indicator appears above the words
SCR LAMP - SOLID. See Selective Catalytic
Reduction (SCR) Monitoring.
