GASKET-OUTLET 1P9390 - Caterpillar

Introduction
When servicing or repairing electric power generation equipment, do the following:a. Make sure the unit is off-line (disconnected from utility power service and/or other generators) and either locked out or tagged DO NOT OPERATE.b. Make sure the generator engine is stopped.c. Make sure all batteries are disconnected.d. Make sure all capacitors are discharged.When power generation equipment is in operation to make tests and/or adjustments, high voltage and current are present. Make sure the testing equipment is designed for and correctly operated for the high voltage and current tests. Failure of improper test equipment presents a high voltage shock hazard to its user.
When the engine-generator, or any source to which the engine-generator is synchronized to, is operating, voltages up to 600V are present in the control panel.Do NOT short these terminals with line voltage to ground with any part of the body or any conductive material. Loss of life or injury could result from electrical shock or injury from molten metal.
Do NOT connect generator to a utility electrical distribution system, unless it is isolated from the system. Personal injury or death is possible by electrical feedback into the distribution system.Open and secure main distribution system switch or, if the connection is permanent, install a double throw transfer switch to prevent electrical feedback. Some generators are specifically approved by a utility to run in parallel with the distribution system and isolation is NOT required. Always check with the utility as to the applicable circumstances.
Service Tools
Control Board Adjustments
Control Board Removed from control panel for clarity purposes only. (1) SW1 switch (spare fault, alarm or shutdown).(2) L6CAL indicator (overspeed calibration).(3) OSSET potentiometer (overspeed set).(4) SW2 switch (overspeed select: 118 or 125).(5) CYTOFF potentiometer (cyclic timer).(6) CYTON potentiometer (cyclic timer).(7) SW3 switch (spare fault, FPT or no FPT).(8) DT potentiometer (duration timer).(9) FPT potentiometer (fault protection timer).Cycle Crank Adjustment
The control board provides the automatic cycle crank function. The control board is factory set for 3 attempts with a 10 second crank and a 10 second rest. On the control board, the duration timer (DT) and the cyclic timer (CYT) control the timing of cycle cranking. If necessary, adjustments can be made to three potentiometers in order to adjust the cycle cranking.CYTON potentiometer = crank time = 0.3 to 24 secondsCYTOFF potentiometer = rest time = 0.3 to 24 secondsDT potentiometer = crank duration timer = 8 to 110 secondsThe duration time must equal or slightly exceed the sum of the crank time and the rest time for the desired number of cranks. For example, the factory default is 10 second crank time, 10 second rest time and 53 second duration time. The duration time is set to 53 seconds to allow for three complete 10 second cranks with 10 seconds of rest between each.Procedure For Cycle Crank Adjustment
Follow this entire procedure if it is desired to completely reset all timers. Otherwise follow only those steps relevant to the particular timer(s) you need to adjust.1. Disconnect the B+ (battery positive) wire from the starting
