TT7S00-HR
TT7S00-HR is an non-isolated two-wire transmitter which converts the
measuring signal of a 3-wire Pt100 RTD into a standardized load-
independent, 4-20 mA current which is linearly proportional to the
measured temperature.
Multi range design with solder pads and potentio-meters.
Flat design gives easy access to terminals and adjustments.
Only 6.5 V voltage drop over the transmitter allows for high loads in the 4-
20 mA output loop.

SAFETY AND WARNING
As all transmitters with potentiometer adjustments,
TT7S00-HR transmitter must not be exposed to heavy
shocks or vibration which may cause the transmitter to
get out of calibration.
To avoid Electrostatic Discharge (ESD) to the
transmitter, which may cause permanent damage,
always ground yourself by touching some ground
equipment before configuring the transmitter.
Always use the cover when the transmitter is not in the
configuration phase. The cover prevents the transmitter
from getting dirt on the soldering pads as well as getting
ESD by accidental touch of the soldering pads.
CONFIGURATION AND CONNECTION
Configuration of the transmitter should always
be carried out by qualified person only.
To ensure that the device can be operated safely
and all functions can be used, check all
cables correctly connected according to
connection diagram.
1. Zero selection
2. Span selection
3. Burn out detection selection
4. Connection
For Input signal: Connect terminal no. 1,2 and 3
as per below connection details.
For Output signal: Connect terminal no. 4 and 5
as per below connection details.
INSTALLATION
On DIN Rail –35 mm DIN
Mounting:
The unit can be snapped onto all DIN rails
according to EN60715. The device must be
mounted horizontally
(Input terminal blocks facing upper wards)
The housing is mounted on the DIN rail by swiveling
it Into place.
Removal:
Release the snap-on catch using a screwdriver and
then detach the module from the bottom edge of
the DIN Rail.
Head Mounting:
Mounting:
The Unit can be mount with 2 screws given with the
sensor head as shown in figure with screw driver.

CALIBRATION
Configuration of the transmitter should always
be carried out before calibration.
It is suggested that the calibration is checked at
least once a year. When a new calibration is
necessary, use calibration instruments with an
accuracy of at least 5 times better than wanted
accuracy for the calibration.
The transmitter is polarity protected and will not be
damaged by connecting the power supply with the
wrong polarity, but the output will be 0 mA.
1. Connect input and output signals according to
figureIn connections. Apply an input signal to give an
output of approximate 12 mA.
2. If the output signal has stabilized after 15
minutes, The transmitter is ready for calibration.
3. Apply Temp. input corresponding to desired
minimum input signal.
4. Calibrate Zero-potentiometer until Iout= 4.00 mA.
5. Apply Temp. input corresponding to desired
maximum input signal.
6. Calibrate Span-potentiometer until Iout= 20.00
mA.
7. Repeat steps 3 to 6 until readings converge.
8. Secure the potentiometer with lacquer.
Calibration is completed.
Subject to recalibrate if range change

TROUBLE SHOOTING
Unit Not Turning ON?
The problem can be bad connection.
First check, connections as per sticker details
Check Jumper selection if they are proper or not?
Unstable/Vague Reading
Check for loose connections.
The reason can be reverse input connections
Output not matching with the expected value
It is a normal tendency to doubt the instrument
performance, when the Output is not matching the
expected value. Kindly make sure that the output is
really incorrect with respect to input signal, before
attempting any re-calibration.
Account for measuring instrument’s inaccuracies,
lead errors and calibration errors. Care must be
taken when measuring Output signal.
Use calibrating instrument of accuracy better than
0.1% for purpose of calibration. If the signal is still
found to be out of tolerance, calibration should be
required.
Zero: -50˚C
Span: 250˚C
