PROTRACseries.Youcanndinformationoftheavailableversionsin
chapter " Mounting preparations".
3.3 Packaging, transport and storage
Your instrument was protected by packaging during transport. Its
capacity to handle normal loads during transport is assured by a test
based on ISO 4180.
The packaging consists of environment-friendly, recyclable card-
board. For special versions, PE foam or PE foil is also used. Dispose
of the packaging material via specialised recycling companies.
Transport must be carried out in due consideration of the notes on the
transport packaging. Nonobservance of these instructions can cause
damage to the device.
The delivery must be checked for completeness and possible transit
damage immediately at receipt. Ascertained transit damage or con-
cealed defects must be appropriately dealt with.
Up to the time of installation, the packages must be left closed and
stored according to the orientation and storage markings on the
outside.
Unless otherwise indicated, the packages must be stored only under
the following conditions:
• Not in the open
• Dry and dust free
• Notexposedtocorrosivemedia
• Protected against solar radiation

4.1 General instructions
We recommended installing the replacement electronics with the
instrument dismounted and brought to a suitable place, e.g. a work-
shop. If it is not possible to dismount the instrument, the electronics
module can also be installed on site at the measuring point.
Warning:
Switchovoltagesupplybeforestartingtheinstallationprocedure.
The replacement electronics may only be installed when the sensor is
in a de-energised state. Non-observance will damage the electron-
ics!
It is absolutely necessary that the following points are observed with
sensorswithExapproval:
ForsensorswithExapproval,makesurethatthereplacementelec-
tronicsmodulehasthesamedesignationastheexchangedelectron-
ics module.
Forexample,anelectronicsmodulewithahardwareversion≥2.0.0
mustbeonlyinstalledinasensorwithhardwareversion≥2.0.0.
4.2 Mounting preparations
The electronics modules are mounted in the electronics compartment
and adapted to the respective sensor. First of all, check by means of
the following lists if you are using a suitable electronics module.
SOLITRAC, POINTRAC, WEIGHTRAC
• PT30E.SV for version four-wire 4 … 20 mA/HART
• PT30E.SSforversion4…20mA/HARTwithSILqualication
• PT30E.SPforversionFoundationFieldbusandProbusPA
MINITRAC
• PT30E.MV for version four-wire 4 … 20 mA/HART
• PT30E.MSforversion4…20mA/HARTwithSILqualication
• PT30E.MPforversionFoundationFieldbusandProbusPA
Ifyouorderedapre-conguredelectronicsmodule(withserialnum-
ber), the serial number of your sensor has already been entered in the
software of the electronics module.
See also chapter " Setup".
WithSIL-qualiedinstruments,onlycorrespondingelectronicsmod-
uleswithSILqualicationmaybeused.Furthermore,onlypre-cong-
ured electronics modules (with serial number) may be used.
ElectronicsmodulesforSILqualiedinstrumentscanonlybeordered
by stating the sensor serial number. Have the sensor serial number
ready when ordering.
Compare the sensor serial number on the electronics module with the
sensor serial number on the type label of your sensor.

To prevent accidental use of a non-permissible electronics module,
the terminal blocks are coded.
On the opposite side, you must code the electronics module accord-
ing to your sensor.
To allow easier handling, the coded pins are mounted on a plastic
plate.Two of these mounting supports are enclosed with the electron-
ics module.
Inthefollowingillustrationthereisanexampleofasensorcoded
withoutExapproval(codingpininterminal4).
There is already a coding pin in terminal 2.This coding prevents the
twoterminalblocksfrombeingexchanged.

Keep in mind that the following work must only be carried out after an
appropriate training from VEGA.
Proceed as follows:
1. Switchothesourcereliably-Setthesourcecontainerto"O"
Secure radiation source from being switched on again.
Warning:
Alwaysswitchotheradiationsourcewhenworkingonthesensor
and secure it against unauthorized or unintentional switching on.
2. Switchovoltagesupply
Warning:
Connectonlyinavoltage-freestate.Switchothevoltagesupplyreli-
ably and secure it against unauthorized or unintentional switching on.
3. Carry out all work in a clean and dust-free environment. If pos-
sible, dismount the sensor.
Caution:
The black rubber protective cap protects the light-sensitive photomul-
tiplier against incident light. Only remove the protective cap when you
are requested to do so in this manual.
4. Check if all parts are included:
- Optical pad
- Plastic spatula
- Special grease (tube)
- Coded pins on mounting support (2 pcs.)
5. Unscrew cover (1) of the electronics compartment (5)
6. Loosen and detach the terminal blocks (6) of the old electronics

5 Setup
5.1 Setup preparations
If you ordered the electronics module by stating the sensor serial
number, it is ready for the setup procedure immediately after installa-
tion and connection to power supply.
ElectronicsmodulesforSILqualiedinstrumentscanonlybeordered
by stating the sensor serial number.
If you ordered the electronics module without programming or you
areusingasuitableelectronicsmodulefromstock,yoursthaveto
load the instrument data after the installation.
The instrument data also include the TAG no., information on the
processttingandsealaswellasactivationdataforasupplementary
electronics.
Entertheserialnumberofyourdeviceintothesearcheldonour
homepage " www.vega.com".
After entering the serial number, the order data of the device are
displayed.
Under " Related documentation"youwillnd"Sensor for electronics
exchange"asanXMLle.SavethisDTMcongurationlewith"Save
as" on your PC and transfer it via PACTware and the Service DTM to
the instrument.
5.2 Setup steps
If the instrument is used in the same application after the electronics
exchange,thepreviousparametersettingsoftheinstrumentmustbe
restored.To do this, you can use the import function of the adjustment
software PACTware with the device DTMs or the copy function of the
display and adjustment module.
If no copy of the parameter settings is available, you have to carry out
a fresh setup. See the operating instructions of the sensor.
OnSILqualiedinstruments,thesettingsoftheelectronicsmustbe
checkedandveriedaftertheelectronicsexchange.Onlythenisthe
instrument again ready for operation.
