Section 12: Troubleshooting
The F01-2000 actuator has passed the functional test performed by Biffi 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.
