BIFFI F01-2000 ELECTRIC ACTUATOR
INSTRUCTION AND OPERATING MANUAL
11 MAINTENANCE
11�1 STANDARD MAINTENANCE
Approx. every 2 years:
Under normal operating conditions, the
F01-2000 is maintenance-free: no actuator
maintenance is formally required, even though
visual inspection for oil leakage or external
visible damages is recommended every two
years. When conditions are severe (frequent
operation or high temperatures), inspect the
oil level and oil quality more often. Replace all
seals that permit oil leakage or water ingress.
The following checks will assure optimum
performance:
• If the stem is external, check that the valve
stem is clean and lubricated. If not, clean it
and lubricate it in order to prevent damages
to the threaded bush.
• Lubricate the internal components of the
coupling block by means of the spherical
head lubricator using suggested greases
(see chapter 4, Lubrication).
• Make sure there are no oil leaks from
the actuator housing. The oil level should
be approx. 20 mm from the fill plug (see
chapter 4, Lubrication).
• Check the external parts for possible
damage and replace them immediately,
if necessary. In case the window glass is
broken, the complete cover must be replaced
(see chapter13, Parts list and drawings for
individual item numbers).
• Repaint all areas where paint is missing.
In chemically aggressive or saline
environments, remove rust from surfaces and
protect with a rust preventative.
11�2 SPECIAL MAINTENANCE
In case actuator failure, please refer to
chapter 12, Troubleshooting for possible
causes.
Spare parts can be required to Biffi: please
refer to the individual item number shown in
chapter 13, Parts list and drawings.
IMPORTANT
Before starting any maintenance operation, make
sure that the mains and all other service voltage
connected to terminal board are switched-off.
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
3.6V lithium battery, 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.
NOTE
Special maintenance is also recommended when,
during operations, the actuator generates an
excessive noise.
• Check that all nuts and bolts securing the
actuator to the valve are tight. If necessary,
re-tighten with a dynamometric key (for
tightening torque values see paragraph 3.4.3,
Installation - Mounting the actuator onto the
valve - Actuator fixing).
• For severe applications or if actuator
operation is infrequent, perform maintenance
checks more often.
• For actuators provided with lithium batteries,
make sure that the display is still visible
when power is off and that there is no
“Battery low” warning message. If “Battery
low” warning appears, replace the battery
(seeparagraph 11.3 Maintenance - Lithium
battery change).
Always replace batteries if the actuator has
been subjected to long periods without power
(see chapter 12, Troubleshooting).
