7.1 OPERATION COUNTERS
The CEA7 control unit records different accumulated readings related to control
unit operation. The counters that record the control unit are:
• Total operating hours counter. The control unit records the number of
hours that the genset engine has been operating. The total operating
hours counter is not resettable.
• Partial operating hours counter. The control unit records the number of
hours that the genset engine has been operating. The partial operating
hours counter can be reset to zero.
• Correct starts counter. The control unit counts the number of correct
starts performed by the control unit. The correct starts counter can be
reset to zero.
• Failed starts counter. The control unit counts the number of failed
starts performed by the control unit. The failed starts counter can be
reset to zero.
• Total energy counter. The control unit counts the total energy produced
by the genset in MWh. The total energy counter is not resettable.
• Partial energy counter. The control unit counts the total energy
produced by the genset in MWh. The partial energy counter can be
reset to zero.
• Daily energy counter. The daily energy counter calculates the energy
generated by the genset from 00:00 on the current day until the
moment the reading is displayed. With the change of day, the energy
accumulated during the day is added to the monthly energy counter
and the daily energy counter is reset to zero.
• Monthly energy counter. The monthly energy counter calculates the
energy generated by the genset from day 1 of the current month until
the day before the reading is displayed. With the change of month, the
energy accumulated is added to the annual energy counter and the
monthly energy counter is reset to zero.
• Annual energy counter. The annual energy counter calculates the
energy generated by the genset from the 1st of January until the month
before the reading is displayed. With the change of year, the annual
energy counter is reset to zero.
