Introduction
Introduction
Thank you for choosing a pHix® Compact
pH / Redox transmitter.
We have done everything possible to make
a pH / Redox transmitter that can fulfill all
your demands.
®
pHix
Compact is very simple to install and
connect, as electrode, fitting and transmitter
is built together in the same NEMA 6X class
enclosure. By doing so, all error sources
like e.g. bad cable connections and leaking
fittings are eliminated.
®
As pHix
on flange in one end and male thread in the
other, the transmitter is very easily mounted
in open tanks as well as pipes without the
usual use of fittings.
You can always contact your representative
or the MJK Service Hotline for advice and
guidance. Also, take a look at http\\:www.
phix.dk.
pHix
Compact is equipped with an uni-
®
is registered trademark of MJK.
Safety instructions
1: Read this manual carefully.
2: Be aware of the environment on the in-
stallation site. Wear necessary protective
equipment and follow all current safety
regulations.
®
3: pHix
Compact can provide a start signal
for dangerous machinery. Always ensure
that connected machinery and other
equipment are effectively being put out
of service (i.e. removal of main fuses,
lock main- and/or security switches in
off position) before commencing setting,
fault finding, service and maintenance
work etc.
Repair
1: Repair must only made by MJK or by a
service representative approved by MJK.
Explosion hazardous areas
®
pHix
Compact must not be installed in
explosion hazardous areas!

Introduction
Construction
®
pHix
Compact is a 4-20 mA 2-wire trans-
mitter with power supply and measuring
signal transmitted over the same two wires.
®
pHix
Compact also has HART® communi-
cation capabilities via the mA wires where
both the primary measuring signal (pH or redox) and the secondary measurement signal
can be read. HART
®
communication gives
the possibility to configure nearly all parameters like measuring ranges, alarm limits,
electrode parameters and also commands
for buffer adjustment.
®
HART
communication requires that pHix
®
Compact is connected to a HART® commu-
nicator or a PLC with HART® interface.
®
pHix
Compact is delivered as standard for
pH or redox masurement, but can also be
delivered for other types of measurement
and non-standard settings.
Product identification
Check that the item(s) delivered corresponds to the ordered item(s). The item
number is printed on a label that is sticked
onto the packing. Shown below is the label

Electrode types
The electrode housing is marked with information about electrode type and measuring range
for the actual electrode:
pH electrode, item no. 160310, 1 - 14 pH, 10 - 80 °C, 0 = 4.6 pH.
pH electrode, item no. 160311, 1 - 14 pH, 10 - 80 °C, 0 = 7.0 pH.
Redox electrode, item no. 160312, 0 - 80 °C.

Mounting
Mounting the electrode
Upon delivery of pHix Compact
®
, the elec-
trode is not mounted.
pHix Compact
®
is configured for the
electrode type included in the delivery, and
therefore it must only be used together with
the electrode with which is was delivered.
pHix Compact
®
shoud be used only with
the electrode type included the delivery.
Contact MJK if other electrode types should
be used.
Replacement of the electrode to another of
same type does not require reconfiguration.
The electrode must not become dry.
Therefore, do not remove the protective
cap before before commissioning of pHix
Compact
®
.
Gasket, O-ring and plug
It is very important that both gasket and
O-ring and packing surfaces is clean and
smooth and without cracks and scratches
to avoid penetration of liquid in the center
plug connection.
Check that gasket and O-ring are complete and
clean ant that they are placed correctly.
Likewise, the connectors in both transmitter
and electrode should be absolutely clean
and dry. Eventually use a dry cloth.

Check that the connectors are
absolutely clean and dry.
