Pinout Diagram
The TL Series Transmitter uses plug-in type screw terminal con-
nectors for all input and output connections. The power supply
connections have a unique plug and socket outline to prevent cross
connection�
!
WARNING: AC and DC input signals and power supply
voltages can be hazardous. Do Not connect live wires to
screw terminal plugs, and do not insert, remove or handle
screw terminal plugs with live wires connected.

Installation Guidelines
Installation
1� Install and wire transmitter per local applicable codes
regulations, the particular application, and good instal-
lation practices�
2� Install transmitter in a location that does not exceed the
maximum operating temperature and that provides good air
circulation�
3� Separate input/output leads from power lines to protect
the transmitter from external noise� Input/output leads
should be routed as far away as possible from contactors,
control relays, transformers and other noisy components�
Shielding cables for input/output leads is recommended
with shield connection to earth ground near the meter pre-
ferred�
!
4� A circuit breaker or disconnect switch is required to dis-
connect power to the meter. The breaker/switch should be
in close proximity to the meter and marked as the discon-
necting device for the meter or meter circuit. The circuit
breaker or wall switch must be rated for the applied voltage
(e�g�, 120VAC or 240VAC) and current appropriate for the
electrical application (e�g�, 15A or 20A)�
5� See Connector Pinouts section for wiring�
6� Use 28-12 AWG wiring, minimum 90˚C (HH) temperature
rating� Strip wire approximately 0�3 in� (7-8 mm)�
7� Re c ommended torque on all terminal plug screws is 4�5
lb-in (0�51 N-m)�

order, but you may change that by following these
directions.
1� WARNING: Disconnect the power from the meter
and disconnect any equipment attached to the outputs before
attempting this procedure� Dangerous voltages may be present�
2� Remove the four screws from the top panel (label side), nuts
are in the bottom panel. Open the case.
3. To select 4-20mA input, move the Voltage/Current jumper to
CURRENT, move the range selection jumper to 4-20mA.
4. To select a voltage input, move the Voltage/Current jumper to
VOLTAGE, move the range selection jumper to the desired volt-
age range (0-5V, 1-5V, 0-10V)�
5� Reassemble the case�
6� It is best to place a small label at the input connector indicating
the required input signal�
NOTE: Input signal calibration is not required in the
TL-DUAL-LOOP and TL-QUAD-LOOP meters.

Each output channel is normally calibrated by the factory.
You may recalibrate the output channels by following these direc-
tions. Each output channel is calibrated using the “Z” (ZERO)
and “S” (SPAN) potentiometers located on the front panel, L1 for
Channel 1, L2 for Channel 2, etc�
1� A calibrated input signal source is strongly recommended�
2� A calibrated 4-20mA measurement meter is strongly recom-
mended for the output�
3� Make sure the input signal type (current or voltage) and
range are correctly set. See INPUT SELECT above.
4� Make sure power is applied to the meter and the PWR LED
is lit�
5. The calibration process takes several iterations, so it is not
necessary to get to 4�00mA or 20�00mA on the first pass�
Rather, set the output progressively more accurately with
each iteration�
6� Apply the low value of the input signal range to the input
connector�
7. Adjust the ZERO potentiometer until a reading of 4.0mA is
observed at the output�
8� Set the input to the high value of the input signal range�
9. Adjust the “S” (SPAN) potentiometer until a reading 20.0mA is
observed at the output�
10� Repeat steps 6 through 9, targeting 4�00mA and 20�00mA,
until stable outputs are achieved. This typically takes 3-4 iter-
ations�
NOTE: Normally, the output is 4-20mA, but the
TL-LOOP-QUAD output can be adjusted to 0mA on the
low end of the range�
NOTE: The 4-20mA output is easily converted into a
voltage by adding a suitable resistor across the output
pins, e�g�, a 0�5% 1/4W 250 ohm metal film resistor,
although accuracy of the resulting voltage will be affect-
ed by the precision and tolerance of the resistor�
