8.4.1. Errors and warnings displayed via FN (Failure Number)
and FS (Failure Select) LEDs
The following table contains errors and warning messages displayed via the FN (Failure Number) and FS
(Failure Select) LEDs.
The error type is indicated by the number of times FN flashes when FS is set to ON.
The error number is indicated by FN flashing when FS is set to OFF.
Number FN

Description Remedial action
1
Parameterization error (Set_Prm_Telegramm)
1 Too many inputs for one valve terminal
(bitwise composition)
→
Check user parameters and
DIP switch
2 Too many outputs for one valve terminal
(bitwise composition)
→
Check user parameters and
DIP switch
3 Parameterization telegram too long
→
Check user parameters and
DIP switch
4 Parameterization telegram too short
→
Check user parameters and
DIP switch
2
Configuration error (Chk_Cfg_Telegramm)
1 Too many inputs for one valve terminal
→
Check identification bytes and
DIP switch
2 Too many outputs for one valve terminal
→
Check identification bytes and
DIP switch
3 Too few inputs for one valve terminal
(preset in parameterization telegram)
→
Check identification bytes and
DIP switch
4 Too few outputs for one valve terminal
(preset in parameterization telegram)
→
Check identification bytes and
DIP switch
5 An identifier has the wrong code
→
Check identification bytes and
DIP switch
3
Main terminal error
1 No supply voltage for main terminal
outputs
→
Check supply voltage
2 Setting for station address is outside
permitted range (0 ... 125)
→
Check PROFIBUS address
on main terminal
3 Error accessing EEPROM
→
Replacement of electronics
may be necessary
4
Peripheral terminal error
1 No supply voltage for peripheral terminal
outputs
→
Check supply voltage
2 Complete failure of a peripheral terminal
→
Check peripheral terminal
RIO bus
After the error has been rectified the valve terminal must be reset by briefly shutting down the supply
voltage.
