•
Counter for the total power (Wh) transferred to the battery during the charge cycles.
•
Total number of discharge cycles.
•
Counter for the total energy (Ah) absorbed from the battery during the discharge
cycles.
•
Counter for the total power (Wh) absorbed from the battery during the discharge
cycles.
•
Number
of “standard” charge cycles from the last “full” charge cycle (resettable to
zero).
Almost all these counters and meters are displayed on the controller's front panel (only the
total supply time counter is not displayed). However, all can be read via the communication
ports (with the Modbus protocol). Some of these counters can be reset by the operator
following a proper procedure, or via the communication ports (they are marked in the list with
“resettable to zero”). All these counters are saved in a non-volatile memory; therefore, they
store their values also when the controller is powered off. Non-volatile memories have limited
life cycles, therefore reducing memory writing to minimum is required. Therefore, a counter
may not be immediately saved as its value changes; consequently, before powering the
controller off, ensure to know when and how the counters were saved.
Counters are saved (all together and in the same time) in the following conditions:
•
At the end of each charge/discharge cycle.
•
Immediately after each engine start (with engine running, not after each start attempt).
•
Immediately after each engine stop (when controller acknowledges the engine
stopped status, not when stop is requested).
•
After each increase of any counter for the engine running hours (any counter, total or
clearable, including the counters for the hours to next maintenance).
•
Every time the controller is set to OFF_RESET.
•
For each hour the controller is powered.
•
When parameters related to maintenance are changed.
Furthermore, counters are saved when they are reset to zero (individually or globally) via front
panel or communication ports. Note that some counters have a decimal part (for example the
minutes-counters associated to hours-counters), which is also saved in a non-volatile memory.
Powering off the controller in an uncontrolled way can cause the loss of the decimal part. It is
enough to switch the controller to OFF-RESET to force data saving, before switching off the
power.
The resetting procedure is common for all the counters, but it only applies to some of them,
based on the page displayed on the multifunctional display. See in paragraph 8.5.5.3 the
description of the display page that contains the counter to be reset to zero.
The controller is provided with a standard hardware clock. It is shown in detail in the page S.06
of the controller. It can be set through the programming menu
“4.7.1 – Date/Time”, using the
following parameters:
•
P.0411: year.
•
P.0412: month.
•
P.0413: day of month.
