1.0 Quick Start Installation
The TA2 is alibrated and onfigured with the information
supplied to MAGNETROL with the order. The instrument
an be installed, wired, and pla e dire tly into operation.
1.1 Probe Installation
Insert the probe into the pipe or du t at the appropriate
lo ation. It is re ommended that the sensor be lo ated on
the enter line of the pipe and that the flow arrow be posi-
tioned in the dire tion of flow.
See Appendix A for re ommended straight run and flow
onditioning plate installation details (if appli able).
1.2 Wiring
Warning: Explosion Hazard. Do not connect or disconnect
equipment unless power has been switched off or the
area is known to be non-hazardous.
NOTE: Make sure the electrical wiring to the TA2 is complete and in
compliance with all regulations and codes. For a maximum
ambient temperature of 80° C use wiring rated up to 264 VAC
and 105° C. For a maximum ambient temperature of 70° C use
wiring rated up to 264 VAC and 95° C.
NOTE: The AC power terminal blocks accept 12-22 AWG wire and the
DC power terminal blocks accept 14-30 AWG wire. Select wire
size consistent with power requirements. The mA output and
pulse output also accept 14-30 AWG wire.
1. Remove the over of the rear ompartment.
2. Pull power supply and ontrol wiring through onduit
onne tion.
3. Conne t power leads to proper terminals.
a. 100 to 264 VAC – Make onne tions to TB1.
Conne t the “hot” wire to L1 and the se ond wire to L2.
b. 15 to 30 VDC – Make the onne tions to TB2.
Conne t the positive wire to (+) and the negative lead
to (–).
NOTE: Ensure that the correct wiring is made to the appropriate ter-
minals. Connecting the DC power to the AC terminals will
cause the unit not to operate. Connecting the AC power to the
DC terminals will blow the fuse and potentially cause damage
to the electronics boards.
NOTE: The green ground screw in the rear of the housing should be
used for earth ground.

2.2 Electrostatic Discharge (ESD)
Handling Procedure
MAGNETROL ele troni instruments are manufa tured
to the highest quality standards. These instruments utilize
ele troni omponents whi h may be damaged by stati
ele tri ity present in most work environments. The following
steps are re ommended to redu e the risk of omponent
failure due to ele trostati dis harge:
1. Ship and store ir uit boards in anti-stati bags. If an anti-
stati bag is not available, wrap board in aluminum foil.
Do not pla e boards on foam pa king materials.
2. Use a grounding wrist strap when installing and removing
ir uit boards. A grounded workstation is also re ommend-
ed.
3. Handle printed ir uit boards only by the edges. Do not
tou h omponents or onne tor pins.
4. Ensure that all ele tri al onne tions are ompletely se ure
and none are partial or floating. Ground all equipment to
a good earth ground.
NOTE: The instrument is rated per IEC 61010-1 for use in Installation
Category II, Pollution Degree 2.

2.3 Installation
2.3.1 Electronics
The instrument is rated for use in Class I, Division 1 and
Class I, Division 2 areas. The en losure is also rated
NEMA 4X. Remote ele troni s (optional) should be
installed in an easy to a ess lo ation within 500 feet
(150 meters) of the sensor. The ele troni s should not be
installed in areas where ambient temperature ex eeds
+175° F (+80° C). If ambient temperature is between
-22° to -65° F (-30° to -54° C), the unit will operate but
the display will not be readable.
Provide watertight seals for all wiring entran es in the
en losure to maintain the NEMA 4X rating. Use appropri-
ate NEC se tion when installing the instrument.
NOTE: A switch or circuit breaker should be installed in close prox-
imity to the equipment and within easy reach of the operator.
It should be marked as the disconnecting device for the
equipment.
2.3.2 Probe/Flow Body
Proper installation of the probe in the pipe or du t is
essential for a urate air or gas flow measurement. Normal
pro edures for installing any type of flow element should
be followed. See Appendix A for additional information on
probe lo ation.
A flow arrow is et hed on the sides of the probe to desig-
nate flow dire tion. The instrument is alibrated with the
flow in this dire tion. Ensure that the flow arrow is aligned
in the dire tion of flow. The instrument is unable to re og-
nize flow dire tion if inserted with the flow arrow in the
wrong dire tion.
It is generally re ommended that the sensor be lo ated in
the enter of the pipe. This lo ation provides less sensitivity
to hanges in flow profile. Sensors mounted through om-
pression fittings have the ability to field adjust the sensor
to the desired lo ation by using the dimensions as shown
in Figure 3.
It may be ne essary to rotate the head of the instrument to
view the display while maintaining the proper flow orien-
tation. This is a omplished by loosening the set s rew on
the bottom of the housing, rotating the en losure to the
desired position and re-tightening the set s rew. The se ond
set s rew is a stop to prevent over rotating the en losure.
See figure 4.

Figure 5
Probe Installation into a Tee Fitting is
Not Recommended
Various methods of mounting the probe in lude ompres-
sion fittings, threads, and flanged onne tions. Refer to
probe model numbers. The insertion probe an be
installed through a ompression fitting. The use of a
bored-through fitting with 3⁄4" or 1" NPT onne tion for
3⁄4" outside diameter tube is re ommended.
The use of Teflon®ferrules should be onsidered if repeat-
ed reposition of the sensor is onsidered. The stainless steel
ferule an only be tightened on e as it makes a permanent
indentation on the probe. If using a ompression fitting
with stainless steel ferrules, ensure that the probe is in the
desired lo ation before tightening.
NOTE: The TA2 flow measurement is based on a fully developed tur-
bulent flow profile in a pipe with the specified inner diameter.
Accuracy will be affected if these conditions are not obtained.
Installing the probe in a tee is not recommended as the flow
profile and the flow area are distorted (See figure 5).
For appli ations where it is desirable to install or remove
the probe without having to shut down the pro ess,
The MAGNETROL Retra table Probe Assembly (RPA)
an be utilized. See the TA2 Sales Bro hure (MAGNETROL
bulletin 54-140) for more information.
WARNING To avoid potential damage or injury, never loosen a
compression fitting while sensor is under pressure.
NOTE: Remote electronics is recommended for operating tempera-
tures greater than +250° F (+120° C) or in locations where the
temperature of the electronics will exceed +175° F (+80° C).
Optionally, an insertion probe with extended probe length to
provide at least four inches (100 mm) between the electronics
and the compression fitting can be utilized.
NOTE: The sensor must be installed in a location where moisture
cannot drip or come in contact with the heated element. Any
contact with condensed moisture in the gas flow will cause a
false high flow indication. Consider mounting the probe at
a 45° angle from top, from the side or bottom of the pipe to
minimize possibility of condensed moisture running down the
probe and contacting the sensor (see Figure 6). In extreme
cases, it may be necessary to insulate or even heat trace the
pipe to prevent the condensation of moisture.
The TA2 with an insertion probe provides a point meas-
urement and assumes that a fully developed profile exists.
See Appendix A. The user has the ability to ompensate
the flow measurements based upon flow profile onsidera-
tions under the Advan ed Configuration se tion of the
software. See Se tion 2.5.11.
NOTE: If equipment is used in a manner not specified by manufacturer,
protection provided by equipment may be impaired.

2.4.2 Ground Connection
The instrument must be grounded in a ordan e with
Arti le 250 of the National Ele tri Code.
2.4.3 4-20 mA Output
A 4-20 mA output (Analog Output 1) of the flow rate is
available at terminal blo k TB3. This output signal is
isolated from the instrument. An a tive or a passive on-
ne tion is available—see definition below.
For units with the optional se ond mA output (Analog
Output 2) this onne tion is available at terminal blo k
TB5; this output is isolated from the input power and
from the primary 4-20 mA loop and shares a ommon
with the pulse output. A passive onne tion is only avail-
able for this loop.
Active Connection—Use the a tive onne tion when
the TA2 is providing power for the 4-20 mA signal.
Use onne tions A- and A+ (see figure 8). The a tive
onne tion will drive a 1000-ohm loop resistan e.
Passive Connection—Use the passive onne tion
when an external power supply or the ontrol system
is used to power the 4-20 mA loop. Use onne tions
P- and P+ (see figure 8). The resistan e is dependent
upon the ustomer-supplied power supply.
2.4.4 Pulse/Alarm Output
The optional pulse signal is isolated from the input power
and from the primary mA loop output. This signal shares a
ommon with the se ondary mA output (Analog Output 2).
The pulse output is available with either an a tive or pas-
sive onne tion.
Pulse/alarm output—Use the a tive onne tion when the
TA2 is providing power for the pulse/alarm output. Use
onne tions A- and A+ on TB4 (see figure 8).

2.5 Configuring the Transmitter
The TA2 ele troni s are easy to set up and onfigure to the
user’s spe ifi ations. When spe ified with the order, the
onfiguration settings are programmed into the instrument
at the fa tory. If not, or if the user wants to modify the
onfiguration settings, follow these instru tions for onfig-
uring the instrument. The primary stru ture of the software
is divided into eight main groups:
All ne essary information an be input using the 4-button
keypad lo ated on the display module or via HART if
supplied. If the TA2 is supplied with HART, PACTware™
an be used to review or hange onfiguration.
NOTE: The Display Module can be rotated in 90-degree increments.
Remove cover, remove the two screws holding the display
module, rotate to desired location and reattach display
module. See Figure 11.
2.5.1 Initialization
When power is first applied to the TA2 there is an initial-
ization period for the sensor to rea h stabilization. During
this time the TA2 will output a 4 mA signal and the dis-
play (if provided) will read “Initializing.”
Only after the sensor has stabilized and a valid flow meas-
urement is obtained will the display show a flow measure-
ment. The output signal will be a tive and the totalizer
will begin ounting.

2.5.3 Password
A password prote tion system restri ts a ess to portions of
the menu whi h affe t the unit’s operation and onfigura-
tion. The default user password installed in the TA2 at the
fa tory is 0 whi h effe tively disables the user password
feature. This allows omplete onfiguration to be done
without entering a password.
If desired, a new user password an be entered in the
Advan ed Configuration in the New Password s reen.
The password an be hanged to any numeri al value up
to 255. On e the password is hanged from the fa tory
default value of 0 then the new password will be required
whenever any onfiguration values are hanged.
2.5.4 Configuration Menu Overview
Configuration of the TA2 is performed by use of a tree-
like menu stru ture. The hart at right shows an overview
of the top level menu items. This basi onfiguration
stru ture is used both with the user interfa e using the
16- hara ter display and keypad and in the HART menu
stru ture (see se tion 2.6.3).
