2.43 Customer data
Address : D170 - D17F
Write authorization : ebm-papst, customer
A total of 16 parameters (of 16 bits each) are available to the customer in this area.
Any values can be stored here.
Fan action is not influenced by these parameters.
2.44 Error history
Error indicator address : D182
1st error address : D184
1st error time Error : D185
Error history 1..13 address : D186, D188, D18A, D18C, D18E, D190, D192, D194, D196, D198,
D19A, D19C, D19E
Error history 1..13 time address : D187, D189, D18B, D18D, D18F, D191, D193, D195, D197, D199,

A) 1st Error
The 1st error occurring in the fan life cycle is stored under the parameter "1st error".
The count of the operating hours counter at this time is also stored in the parameter "1st error time".
The parameters are written automatically by the fan.
B) Error history
The last 13 errors that have occurred in the fan are stored in the error history.
The corresponding count of the operating hours counter is stored for each error in the parameter
"Error history time". The parameters are written automatically by the fan.
The error indicator (holding register D182) gives the address of the last error to occur in the error history.
The preceding error is then at the preceding address.
Example:
Error indicator = D196
Then:
D196 Last error (error n) D197 Time of last error (error n)
D194 Error n-1 D195 Time of error n-1
D192 Error n-2 D193 Time of error n-2
D190 Error n-3 D191 Time of error n-3
D18E Error n-4 D18F Time of error n-4
D18C Error n-5 D18D Time of error n-5
D18A Error n-6 D18B Time of error n-6
D188 Error n-7 D189 Time of error n-7
