BIFFI FAIL SAFE ELECTRIC ACTUATORS, MODEL EFS2000V4
InstructIon and operatIng Manual
17.5.12 Warning table
Configuration object nr.: Number indicates the number of the parameters to be configured. To clear the alarm the table of all ICON2000
parameters is necessary. Please contact Biffi after sales service to solve the problem.
If the alarm message is ‘CONFIGURATION OBJ 9999’ only one of the ICON2000 parameters needs to be changed. For
instance: enter the SET-UP menu, actuator set-up, torque set-up, and either increase or decrease the closing torque
by1%. As the alarm message disappears re-enter the SET-UP menu, actuator set-up, torque set-up, and set the
previous value (see paragraph 9.1.2. of document BIFRM-0003-EN: ‘Set-up routines, actuator set-up, torque set-up’).
Hardware nr.: Number indicates the module that is not working. The problem may be due to a malfunction of the module, to an
incorrect wiring between modules, or to an incorrect configuration of the ICON2000. Please contact Biffi after sales
service to solve the problem. The following hardware alarms can be detected:
• Hardware 1 = incorrect coding of local push buttons and selector
• Hardware 2 = incorrect configuration of Ain/Aout optional module
• Hardware 3 = no communication between Ain/Aout optional module and base card
• Hardware 4 = incorrect configuration of type of terminal board
• Hardware 5 = no communication between terminal board and base card
• Hardware 6 = incorrect configuration ICON2000/F01-2000
• Hardware 7 = incorrect configuration of type of bus card
• Hardware 8 = no communication between bus card and base card
• Hardware 9 = EFS clutch card failure
• Hardware 10= no communication between EFS clutch card and base card
