r2110[0...3] CO: Warning number - - - - - U16 2
Displays warning information.
A maximum of 2 active warnings (indices 0 and 1) and 2 historical warnings (indices 2 and 3) may be
viewed.
Index: [0] Recent Warnings --, warning 1
[1] Recent Warnings --, warning 2
[2] Recent Warnings -1, warning 3
[3] Recent Warnings -1, warning 4
Notice: Indices 0 and 1 are not stored.
Note: The LED indicates the warning status in this case. The keypad will flash while a warning is active.
P2111 Total number of
warnings
0 - 4 0 T - - U16 3
Displays number of warning (up to 4) since last reset. Set to 0 to reset the warning history.
P2113[0...2] Disable inverter
warnings
0 - 1 0 T - - U16 3
Switches off reporting of inverter warnings. Can be used in conjunction with P0503 as an adjunct to keep-
running operation.

r2114[0...1] Run time counter - - - - - U16 3
Displays run time counter.
It is the total time the inverter has been powered up. When power is switched off, the value is saved, and
then restored on powerup. The run time counter will be calculate as followed:
Multiply the value in r2114[0] by 65536 and then add it to the value in r2114[1]. The resultant answer will
be in seconds. This means that r2114[0] is not days. Total powerup time = 65536 * r2114[0] + r2114[1]
seconds.
Example: If r2114[0] = 1 and r2114[1] = 20864
We get 1 * 65536 + 20864 = 86400 seconds which equals 1 day.

P2115[0...2] Real time clock 0 - 65535 257 T - - U16 4
Displays real time.
All inverters require an on-board clock function with which fault conditions may be time-stamped and
logged. However, they have no battery backed Real Time Clock (RTC). Inverters may support a software
driven RTC which requires synchronization with the RTC supplied via a serial interface.
The time is stored in a word array parameter P2115. The time will be set by USS Protocol standard "word
array parameter write" telegrams. Once the last word is received in index 2, the software will start running
the timer itself using internal running 1 millisecond tic. Hence becoming like RTC.
If power-cycle takes place, then the real time must be sent again to the inverter.
Time is maintained in a word array parameter and encoded as follows - the same format will be used in
fault report logs.
