11 Device Configuration/Setting through FF communication
When the 266 PdP transmitter has to be used in a FF project and/or connected to any type of Host, the first operation is to import
in the Host the Device drivers, typically the EDD and CFF files.
The EDD and CF files can be downloaded from the ABB website
www.fieldcommgroup.org/registered-products
When the DD and CF files has been imported in the Host then:
• The blocks implemented in the device and their parameters are visible and addressable for read or write operations.
• The device can be instantiated into a network project assigning a node address and TAG and its Function Blocks can be
instantiated into a Function Block Application (FBAP).

Commissioning

Once the transmitter has been installed, it is put into operation by switching on the operating voltage.
Check the following before switching on the operating voltage:
• Process connections
• Electrical connection
• The impulse line/s and the measuring chamber of the measuring equipment must be filled with the measuring medium.
The transmitter can then be put into operation. To do this, the shut-off valves must be actuated in the following sequence (in the
default setting, all valves are closed):
(Differential models) 266Dx or 266Mx
1 Open the shut-off valves on the pressure tap connection (if present).
2 Open the pressure equalization valve of the manifold.
3 Open the positive shut-off valve (on the manifold)
4 Open the negative shut-off valve (on the manifold)
5 Close the pressure equalization valve..
(Gauge & Absolute models) 266Gx, 266Ax, 266Hx, 266Nx, 266Px, 266Vx
1 Open the shut-off valve on the pressure tap connection (if present).
2 Open the positive shut-off valve.
To put the transmitter out of operation, carry out the steps in reverse order.
IMPORTANT
For the absolute pressure transmitters model 266AS or 266NS or 266VS with sensor range C, F or G, please be aware that the
measuring equipment will have been overloaded by the atmospheric pressure due to the long periods of transport and storage
involved. For this reason, you will need to allow a starting time of approx. 30 min. after commissioning, until the sensor has
stabilized to such an extent that the specified accuracy can be maintained.
If, when using „intrinsically safe" transmitters, an ammeter is connected to the output circuit or a modem is connected in
parallel while there is a risk of explosion, the sums of the capacitances and inductances of all circuits, including the transmitter
(see EC-type-examination certificate) must be equal to or less than the permissible capacitances and inductances of the
intrinsically safe signal circuit (see EC-type-examination certificate for the supply unit). Only passive or explosion-proof devices
or indicators may be connected.
If the output signal stabilizes only slowly, it is likely that a large damping time constant has been set on the transmitter.
Correction of the mounting position
During installation of the transmitter, zero shifts caused by mounting (e.g., a slightly oblique mounting position due to a remote
seal, etc.) may occur; these must be corrected.
IMPORTANT
The transmitter must have reached its operating temperature (approx. 5 min. after startup, if the transmitter has already
reached the ambient temperature).
