CHAPTER
B
STORAGE AND PRE-INSTALLATION
1. Tests to be carried out when the actuator is received
If the actuator is received already mounted on the valve, all operations should have already
been performed during valve/actuator assembly.
- Check that the display is active.
- Turn the handwheel until the valve is in a completely open position;
- check that the display reads 100% indicating that the valve is completely open;
- rotate the handwheel clockwise and bring the valve to a completely closed position;
- check that the display reads 0% indicating that the valve is completely closed.
If the test result is satisfactory, the actuator has already been adjusted and you can proceed
with the electrical connection.
If the actuator is delivered separately from the valve, or the above procedure shows that the
position is incorrect, all operations described in this manual must be carried out.
- Check that no damage has occurred during transport, especially to the push-buttons, the
display area glass and the selector.
- Check the information on the nameplate: serial number and performance data (nominal
torque, operation speed, protection class, motor supply voltage, etc.), and verify the
corresponding data on the display (see sect.618/2 chapt. L).
Make sure all accessories have been received with the shipment, as described in the
delivery documentation.
2. Storage procedure
Important: Not performing the following procedures will invalidate
the product guarantee.
2.1 GENERAL
The actuator leaves the factory in perfect condition, as guaranteed by an individual test
certificate. In order to maintain these characteristics until the actuator is installed on site,
proper procedures must be taken for preservation during the storage period.
BIFFI actuators are weatherproof to IP 66/IP 68. This condition can only be maintained if the
units are correctly installed/connected on site and if they have been correctly stored.
The standard plastic plugs used to close the cable entries are not weatherproof, they just
prevent the entry of undesired objects during transport.
