Section 12: Troubleshooting
The F01-2000 actuator has passed the functional test performed by Bif Quality
Assurance personnel.
!
WARNING
The actuator is non-intrusive. The control compartment was sealed in dry and clean
conditions and contains no site serviceable components. Do not open it unless absolutely
necessary. Unauthorized access will invalidate the warranty.
!
WARNING
Since the control compartment contains a 3.6 V lithium battery type LS 14500C (SAFT),
only open it in safe area. If the actuator is located in a hazardous area, a “hot work” permit
must be obtained unless the actuator can be moved to a non-hazardous area.
If the actuator does not work before troubleshooting, make sure that:
• The numeric display indicates xx %
• The local selector is not in OFF
• The main supply voltage is the same as stated in the nameplate menu
• You move the local selector to OFF and check that the alphanumeric display shows
one of the following messages:
— “normal, off, stop”
— “alarm, off, stop”
— “warning, off, stop”
If the above checks are satisfactory, try to locate the fault using the diagnostic facilities.
12.1 The Electronics Do Not Switch on
When Powered
• Check that the value of the main voltage on terminals L1, L2, L3 is correct.
• Remove the cover of the compartment where the electronic cards are located.
• Check the fuse mounted on the power card. Replace it if burnt.
• If the fuse is OK, check the wires between terminals L1, L2, L3 and connector M1 of
the power card. If it is correct, replace the power card.
