These commands may be used to clear various historical data.
• CLEAR LAST TRIP DATA: The Last Trip Data may be cleared by executing this command.
• CLEAR MWh and Mvarh METERS: Executing this command will clear the MWh and Mvarh metering to zero.
• CLEAR PEAK DEMAND DATA: Execute this command to clear peak demand values.
• CLEAR RTD MAXIMUMS: All maximum RTD temperature measurements are stored and updated each time a new
maximum temperature is established. Execute this command to clear the maximum values.
• CLEAR ANALOG I/P MIN/MAX: The minimum and maximum analog input values are stored for each Analog Input.
Those minimum and maximum values may be cleared at any time.
• CLEAR TRIP COUNTERS: There are counters for each possible type of trip. Those counters may be cleared by exe-
cuting this command.
• CLEAR EVENT RECORD: The event recorder saves the last 40 events, automatically overwriting the oldest event. If
desired, all events can be cleared using this command to prevent confusion with old information.
• CLEAR GENERATOR INFORMATION: The number of thermal resets and the total generator running hours can be
viewed in actual values. On a new installation, or if new equipment is installed, this information is cleared through this
setpoint.
• CLEAR BREAKER INFORMATION: The total number of breaker operations can be viewed in actual values. On a new
installation or if maintenance work is done on the breaker, this accumulator can be cleared with this setpoint.
