9 Troubleshooting

9.1 Overview

This section provides troubleshooting suggestions for the most
common problems occuring in the field.

Important. Procedures described in the following paragraphs
will help the user to verify that 266 pressure transmitter and
wireless communication network are correctly in place.

9.2 Device-related issues

9.2.1 Device does not power on

When the user receives a 266 WirelessHART pressure
transmitter, the first step to be taken is to power the device on.

After removing the battery pull-tab grabbing it firmly and pulling
the cell will give power supply to the electronic module LCD
display will go live for 30 seconds and then it will go off.

If this doesn’t happen the possible cause could be:

Possible cause

Solution

Battery discharged

Change the battery (spare part number
DR3051)

Display or battery not well
connected

Check HMI contacts or invert battery position
into the terminal block

Terminal block defect

Check battery and terminal blocks contacts

In case the device is not powering, please check if the battery
is still in good conditions and it has not been exposed to high
temperatures for long periods of time. To install a new battery,
please follow below instructions

1. Install 266 WirelessHART pressure transmitter properly,
according to ABB practices explained in the present

document using an approved thread sealant on all

connections.

2. Unscrew the battery cover from the wireless device.

    Battery lays on the opposite side of the display (if installed)
    as indicated by the writing “Field Terminals” engraved on
    housing neck.

3. Remove and replace the battery paying attention to the
polarity.

Note. Wireless devices should be powered up only during the
network setup and beginning with the closest device to the
Gateway. This will result in a simpler and faster network installation.
For further information about the battery, please refer to paragraph
6.6 of this document.

  4.  Close the housing cover so as to have a metal-to-metal
    contact but do not over tighten. If the installation of the
    battery as been properly performed, the LCD display will
    go live for 30 seconds and then it will go off.

Important. Battery part number is DR3051. To get spares batteries,
please get in touch with your local ABB service reference.
Replacements with non-ABB batteries is forbidden and will lead to
certification invalidity.

9.3 Network-related issues

9.3.1 General

Network joining could represent a critical point for a wireless
transmitter.

Basic preliminary setting for joining consists in writing two
parameters both into the device and into the Gateway. These
parameters are:

— Network ID

— Join Key

Important. Network ID and Join Key are to be always the
same both on field instrument and Gateway.

It is also necessary to write the LONG TAG for communication
via Ethernet TCP/IP within the Asset Vision Basic projects.

The above-mentioned parameters can be set using:

— Asset Vision Basic wired to device dedicated terminals
through a HART modem.

— Hand-held terminal wired to device dedicated terminals

— Local HMI menu

9.3.2 Device does not join the network

After the basic settings have been correctly executed, a typical
anomalous situation is that the device does not join to the
wireless network.

Network is joined when the radio signal icon

is steady

visible on the upper right-hand corner of the HMI (if installed).

Possible cause

Solution

Power supply is missing

Access the “Z” button and depress it for few
seconds until the display goes live. If this will
not happen, see section 9.2.1

Anyway, device will more likely not join the network due to a
radio signal failure. Radio failure can be identified thanks to the
above-mentioned icon.
