Applicability:
This manual applies to all instruments of the TF5 series with firmware version 1.x, where 1.x can be 1.0, 1.1,
etc. Changes to the last digit of the version number reflect minor firmware changes that do not affect the
manner in which the instrument should be operated.
1 Overview
The TF5 transmitter measures temperature based on the data provided by an external PT100 4-wire RTD
probe. We offer a wide selection of plug-in RTD probes. In principle, the TF5 can be used with any suitable
third party RTD probe. The TF5 series is designed for fixed installation in HVAC and light industrial
applications where a high measurement accuracy is required at temperature conditions within the range of
-100 to 600°C (-148 to 1,112°F) – depending on the RTD probe model. The electronics operating range is
limited to -40…60 °C (-10…60°C with the optional LC display).
The TF5 features a robust housing. Digital signal processing ensures consistent product performance and
also facilitates the task of field maintenance with features such as potentiometer free – digital calibration.
Based on the ROTRONIC AirChip 3000 digital technology the TF5 series offers the following functions:
• User configurable settings
• Temperature calibration and adjustment
• Simulator mode
• Fail safe mode
• Data recording
The ability for the user to easily update the AirChip 3000 firmware means that instruments of the TF5 series
can be kept up-to-date regarding any future functionality improvement.
TF5 transmitters with analog output signal: two types of electronic circuit are available: TF52: 2-wire, loop
powered (4…20 mA current signal) and TF53: 3-wire (voltage or current signal). Both circuit types provide
linear analog outputs signals for transmission over a length of cable to a remote display, recorder, controller or
data processing unit.

3 General description
3.1 Power supply
Depending on the circuit type, the TF5 requires the following power supply:
a) TF52 (2-wire, loop powered) : 10…28 VDC - depending on the load connected to the output. The
minimum supply voltage can be determined as follows:
V min = 10 V + (0.02 x Load*) *Load resistance in ohms.
For the maximum load of 500 Ω, the minimum supply voltage is 10 + (0.02 x 500) = 20 VDC. The
maximum current consumption is 20 mA.
b) TF53 (3-wire with analog outputs): 15 to 40 VDC (see note below ) or 12 to 28 VAC. With both output
circuits closed, the maximum current con su mpti on is 30 mA.
Note: depending on the type of output signal, the TF53 will operate with the following minimum voltage
0…1 V outputs: 5 VDC or 5 VAC
0…5 V outputs: 10 VDC or 8 VAC
0…10 V outputs: 15 VDC or 12 VAC
0…20 mA or 4 …20 mA outputs: 6 VDC or 5 VAC with 0 Ω load
15 VDC or 12 VAC with 500 Ω load
3.2 External Pt100 RTD probe and probe connector
The TF5 is equipped with a 4-pin Binder conne ctor seri es 71 2 and is compatible with any of the ROTRONIC
Pt100 RTD probes (see separate manual E-M-Pt100-Probes). In principle, the TF5 can be used with any third
party 4-wire Pt100 RTD probe and is shipped together with the necessary connector hardware to
accommodate a third party probe
Note: seen from the solder side of the TF5 probe connector

3.3 Analog output signal (TF52 and TF53)
TF52 and TF53
With the ROTRONIC HW4 software the scale of the analog temperature output can be set within the
numerical limits of -999.99 and 9999.99.
The D/A converter used to generate the analog output signal features a 16-bit resolution and exhibits a small
positive offset at the bottom of the signal range as indicated below:.
TF52
The analog signal is always 4…20 mA,
TF53
The ROTRONIC HW4 software allows changing the type of output signal to one of the following: 0…20 mA,
4…20 mA, 0…1V, 0…5V or 0…10V. No calibration or adjustment is required after changing the type of output
signal.
In the case of a voltage output signal, load requirements apply to the external device or circuit connected to
the TF53 transmitter. These requirements are defined in the “Operation” chapter
Communication protocol options
The measurement data can be read without having to use the ROTRONIC HW4 software. Starting with
firmware version 1.3, the TF5 offers the following communication protocol options (ASCII) which can be
selected by connecting the TF5 to a PC running the ROTRONIC HW4 software (version 2.1.1 or higher):
o RO-ASCII: this is the standard (default) communication protocol used by all AirChip 3000 devices and by
the HW4 software. In principle, this protocol supports all of the AirChip 3000 functions but some of the
functions require a certain amount of computations to be carried out by an external device such as a PC.
o Custom: this communication proto col can be used to provid e compat ibi lity of the TF5 with an existing
communication system. The Custom communication protocol is limited to reading measurement data from
the TF5. Functions such as device configuration, humidity and temperature adjustment, etc. are not
supported. The Custom protocol is applicable to all AirChip 3000 devices with a digital interface and
allows RS-485 networking
o Modbus: the Modbus protocol available with the TF5 is limited to reading measurement data from the
TF5. Functions such as device configuration, humidity and temperature adjustment, etc. are not
supported by the Modbus protocol.
When using either the RO-ASCII or the Custom protocol, the TF5 can be set to send data automatically after
each refresh cycle without requiring a data request. When this mode is enabled, the receiving device must be
listening at all times in order to get the measurement data.

3.4 Service connector
The service connector is a UART digital interfac e (Universal Asynchronous Receiver Transmitter) with a miniUSB type connector. This allows connecting the TF5 either to a PC running the ROTRONIC HW4 software or
to a probe input of another instrument that is compatible with the HygroClip 2 (HC2) probes. In both cases a
service cable is required. See “Maintenance” for the location of the service connector and for the type of
service cable to be used.
• Connecting the TF5 to a PC is used to con figur e the TF5, gain access to the TF5 functions such as
temperature adjustment, read data from the TF5 on the PC and update the AirChip 3000 firm ware.
• Connecting the TF5 to the probe input of another instrument is useful only when the other instrument has
its own display and keypad, and has an internal menu equivalent to the menu of the HP23 hand-held
calibrator. The connection allows showing the data measured by the TF5 on the other instrument display
and also allows using the other instrument internal menu to do for example a temperature adjustment of
the TF5.
4 User configurable settings and functions
The TF5 ships configured as specified on the custo mer order. Models with analog outputs can be installed
and used just as any conventional humidity and temperature transmitter and most users will never need to use
the TF5 configurable settings and functions. Models with a digital interface generally require some
configuration by the user.
Making use of the TF5 configurable settings and functions is entirely up to the user and the appropriate
settings depend on the user application. We have provided below a short description of the TF5 functions and
also indicated the factory default settings.

5 Mechanical installa t ion
5.1 General guidelines
Relative humidity is extremely dependent on temperature. Proper measurement of relative humidity requires
that the probe and its sensors be at exactly the temperatur e of the environ me nt to be meas ured. Be cause of
this, the location where you choose to install the probe can have a significant effect on the performance of the
instrument. The following guidelines should guarantee good instrument performance:
a) Select a representative location: install the probe where humidi ty , temper at ure and pr es s ure
conditions are representative of the envir on me nt to be meas ured.
b) Provide good air movement at the probe: air velocity of at least 200 ft/ minute (1 meter/second)
facilitates adaptation of the probe to changing temperature.
c) Avoid the following: (1) Close proxim ity of the probe to a heating element, a cooling coil, a cold or
hot wall, direct exposure to sun rays, etc. (2) Close proximity of the probe to a steam injector,
humidifier, direct exposure to precipitation, etc. (3) Unstable pressure conditions resulting from
excessive air turbulence.
d) Immerse as much of the probe as possible in the environment to be measured.
e) Prevent the accumulation of condensation water at the level of the sensor leads. Install the
probe so that the probe tip is looking downward. If this is not possible, install the probe horizontally.
5.2 TF5 enclosure
The TF5 enclosure consists of a base and a cover held together with 4 screws. To open the enclosure, use a
metric 2.5 mm hex k ey. Prior to re-assembling the enclosure, verify that the red seal is sitting properly in its
groove on the base.
Mounting hardware
Method 1: The TF5 is supplied with 2 screws, 2 drywall anchors and two rubber washers. The base of the
enclosure has 2 screw-wells (see drawing) that are normally closed at the bottom. Use the template provided
with the TF5 to drill mounting holes in the wall and insert the drywall anchors. Place a rubber washer on each
screw. Insert a screw in each well and push to open the bottom of the well.
Method 2: When a DIN-rail (35 mm / 1 3/8 “) is available use part AC5002 (not included). This is a DIN-rail
mounting kit consisting of 2 clamps that attach to the back of the enclosure with the screws provided.

6 Electrical installation
6.1 General wiring guidelines
Power supply wiring
Heavy machinery and instrumentation should not share the same power supply wiring. If this cannot be
avoided, noise filters and surge protector s should be used. Most UPS devices have those features alrea dy
integrated.
General guidelines for signal cables
The following guidelines are derived from European Standard EN 50170 for the transmission of signals by
copper wires. When plannin g an installation, the rules provided by EN 50170 should be followed under
consideration of local circumstances to determine the position of machines and equipment.
All ROTRONIC products are tested for Electromagnetic Compatibility according to EMC Directive
2004/106/EG and following European standards:
- EN 61000-6-1: 2001, EN 61000-6-2: 2005
- EN 61000-6-3: 2005, EN 61000-6-4: 2001 + A11
Whenever the level of electromagnetic interference is expected to be high, both the instruments and signal
cables should be placed as far away as possible from the source of interference.
In general, signal cables should be installed in bundles or channels / conduits, separate from other cables as
indicated in the table below:
• Bus signals such as RS485
• Data signals for PCs, printers etc.
• shielded analog inputs
• unshielded direct current (<= 60V)
• shielded process s ignals (<= 25 V)
• unshielded alternate current (<= 25V)
• coaxial cables for CRT monitors
• direct current from 60 V to 400 V
(unshielded)
• alternate current from 25V to 400 V
(unshielded)
• direct and alternate current > 400 V
(unshielded)
• Telephone lines
• lines leading into EX-rated areas

Lightning protection
Cabling in areas with a risk of lightning requires a lightning protection. For cabling underground in between
buildings, we recommend the use of special fiber optic cables. If this is not possible, use copper cables that
are suitable for underground installation.
6.2 Cable grip and cable specifications
The TF5 is supplied either with one M16 sealing cable grip or with a ½” conduit adapter. The M16 cable grip
provides effective sealing only with cables having the proper outside diameter. Preferably, use a cable with an
outside diameter of 6 to 7 mm (0.236 to 0.275 inch) with 18 AWG wires.
6.3 Wiring
6.3.1 TF52: 2-wire, loop powered transmitter
Electrical diagram
The maximum permissible cable length connecting the TF52 to other devices
is determined by the total resistance resulting from the addition of the cable
resistance and that of the devices connected in series with the unit. This
resistance should not exceed 500 ohms.

6.3.2 TF53: 3-wire transmitter
Electrical diagram for voltage outputs
The maximum permissible cable length can be
determined under consideration of the voltage drop
caused by the current flowing to the devices
connected to the unit. The voltage drop in the cable
depends both on cable resistance and on the
equivalent resistance of the devices connected in
parallel to the unit. The total resistance connected to
each unit output should be at least 1000 ohms. Cable
resistance should not be more than 1/1000 of the load
resistance.
Minimum load requirements apply to the external device or circuit connected to the TF5 transmitter. These
requirements are defined in the “Operation” cha pter

7 Maintenance
7.1 Service cable
• Cable AC3006 is used to connect the TF5 to a USB port of a PC running the ROTRONIC HW4 software.
• As an alternative, cable AC2001 is used to connect the TF5 to a probe input of the HP23 hand-held
calibrator. For service purposes, the HP23 offers essentially the same functionality as the HW4 software.
7.2 Location of the service connector (mini USB type)
WARNING: the service connector is a UART interface with a mini-USB connector type. Do not connect the
service connector directly to the USB port of a PC or hub.
The service connector can be accessed without opening the enclosure after removing the small red sealing
cover.
7.3 Periodic calibration check
a) Procedure for adjusting the TF5 from the optional keypad
The optional keypad of the TF5 allows a 1-point adjustment of temperature aga ins t a refer ence . This has
the effect of adding the same offset to all measured values. A 2-point adjustment is not possible from the
keypad and requires using either a PC with the HW4 software installed or another instrument such as
the HP23 hand-held calibrator.
• When temperature is stable, press the MENU key to show the internal menu on the display
• Use the (-) key to select Temperature Adjust and press the ENTER key
• Make sure that the text line beginning with RefValue is highlighted and press the ENTER key
• Use the (+) or (-) key to change the reference value as desired
• Use the (-) key to highlight the Adjust text line and press the ENTER key
• The TF5 confirms the adjustment with the message “Adjust OK”
• Press the MENU key twice to exit the menu and return the TF5 to normal operation
Notes:
o The calibration point is automatically deleted from the TF5 memory after an adjustment
o Because the TF5 has no real time clock, the date of the adjustment is not written to the TF5. If
retaining the adjustment date is important, use the HW4 software to adjust the TF5.

b) Procedure for adjusting the TF5 with the ROTRONIC HW4 software:
• Use cable AC3006 to connect the serv ice connector of the TF5 to a USB port of a PC with the HW4
software installed. Note that the ROTRONIC USB driver must be installed on the PC as explained in
the HW4 manual E-M-HW4v2-Main.
• Start HW4 on the PC and search for the TF5 (HW4 Main Menu Bar > Devices and Groups > Search
for USB Masters).
• After finding the TF5 with HW4, expand the device tree to see the TF5 functions.
Select Probe Adjustment.
• For further instructions see HW4 manual E-M-HW4v2-A2-001
7.4 Validation of the output signals transmission
If so desired, transmission of the TF5 output signals can be validated by using the simulator function. The
HW4 software is required to enable and configure this function. When this function is enabled the TF5
generates fixed digital and ana log sign al s as specified by the user. For instructions see document
E-M-HW4v2-F2-017
8 Firmware updates
Firmware updates will be available on the ROTRONIC website for downloading. Firmware files are given a
name that shows both to which device the file applies and the version number of the firmware. All firmware
files have the extension HEX. Procedure for updating the firmware:
• Use cable AC3006 to connect t he serv ice connector of the TF5 to a USB port of a PC with the
ROTRONIC HW4 software installed. Note that the ROTRONIC USB driver must be installed on the
PC as explained in the HW4 manual E-M-HW4v2-Main.
• Copy the firmware update fi le from the ROTRONIC website to the PC.
• Start HW4 software on the PC and search for the TF5 (HW4 Main Menu Bar > Devices and Groups >
Search for USB Masters).
• After finding the TF5, expand the device tree to see the TF5 functions. Select Device Manager. In the
Device Manager menu bar select Tools > Firmware Update. For instructions see document
