2.41  Customer data 
Address    : D170 - D17F 
Write authorisation  : ebm-papst, customer 
For the customer, a total of 16 parameters (each with 16 bits) is available in this range. 
Any values can be stored here. 
The behaviour of the fan is not influenced by these parameters. 
2.42  Error history 
Address of error indicator    : D182 
Address of 1st error:      : D184 
Address of 1st error time:    : D185 
Address of error history 1 to 13    : D186, D188, D18A, D18C, D18E, D190, D192, D194, D196, D198,  
 D19A, D19C, D19E 
Address of error history time 1 to 13  : D187, D189, D18B, D18D, D18F, D191, D193, D195, D197, D199, 
           D19B, D19D, D19F 
Write authorisation      : ebm-papst 
A) 1st error 
The first error that is detected in the service life of the fan is stored under the "1st error" parameter. 
At the same time, the reading on the operating hour counter at this time is stored in the parameter "1st error 
time". The parameters are automatically written to by the fan. 
B) Error history 
The error history contains the last 13 errors that were detected in the fan. 
The record of each error includes the respective operating hours counter reading in the parameter "Error 
history timing". The parameters are automatically written to by the fan. 
The error indicator (D182) specifies the address of the last error to be detected in the error history. 
The previous 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
