Instructions for start-up
3.2 Cable type
The cable must be specify for Foundation Fieldbus type A
For example:
Belden 3076F)
1 pair 18 AWG
Resistance 5.86 ohms/1000ft @20°C
Nominal mutual capacitance @ 1kHz: 80pF/m (24pF/ft)
Type shield: shielding braid or foil
Fieldbus cable has to be separated from the other cables with a distance of at least 20cm.
It will use a specific cable path and be connected to the earth.
It is also necessary to check that all actuators are at the same earth electrical potential.
3.3 Fieldbus connection
Junction box terminals 35-36:
Shield: Cable shielding
End of line termination
A termination has to be installed at each end of line. This termination is not built in
the actuator.
3.4 Set-up
The INTELLIBUS module is selected in the menu:
Use the local control button of the actuator. (refer: NR1151).
In the menu select Change
then select Fieldbus
then select Card FF present and choose (yes)
Confirm OK with the red button.
To save, select return in each submenu until to read:
RETURN
(Change OK?)
Confirm OK with the red button.
When the Fieldbus card is selected then the menu shows
the other configurations:
Lost communication: In case of loss of communication the actuator operates to
the close position, open position or stays in position.
