Error
D -> C
C -> D
Setting the bit D -> C causes all the parameters of the data area (holding registers D100 - D17F) for which the
customer has write authorization to be copied to the customer setting (holding registers D200 - D27F).
A minimum of "Customer" authorization is required for setting this bit.
Setting the bit C -> D causes all the parameters of the customer setting (holding registers D200 - D27F) for
which the customer has write authorization to be copied to the data area (holding registers D100 - D17F).
"End customer" authorization is sufficient for setting this bit.
On completion of copying, the bit is automatically reset by the fan.
If an error occurs during copying, the "Error" bit is set and copying is terminated
2.7 Operating hours counter
Address : D009
Write authorization : ebm-papst
Coding:
The operating hours counter is incremented by 1 for every two hours during which the fan runs.
A maximum of 131070 hours (approx. 15 years) can be counted with 16 bits.
The operating hours counter will no longer be written in the event of an overflow, i.e. it remains on 65 535.
2.8 Operating minutes counter
Address : D00A
Write authorization : ebm-papst
Coding:
The operating minutes counter is incremented by 1 for every full minute for which the fan runs. When it
reaches 120 minutes, the counter is reset and starts again at 0.
