Digital transmitter for temperature
Congratulations on your purchase of the new state-of-the-art HYGRO-
FLEX TF5 SERIES transmitter. Please read these short instructions
carefully before installing the device.
General description
The HYGROFLEX5 SERIES devices are transmitters for transmission of
temperature measurements. Compatible with PT100 probes. These
short instructions are limited to a description of the main functions
and installation of the device. The detailed instruction manual can be
found on the internet at:
www.rotronic-humidity.com
Mechanical installation
General recommendations
Follow the guidelines below to ensure optimum performance:
a) Select a representative installation site: Install the probe at a point where the temperature are
representative for the environment that is to be measured.
b) Make sure there is suffi cient air movement around the probe: An air fl ow of at least 1 metre/
second accelerates and facilitates adjustment of the probe to changing temperatures.
c) Avoid:
(1) Probe too close to heating elements, cooling coils, cold or hot walls, direct sunlight, etc.
(2) Probe too close to steam, injectors, humidifi ers or direct precipitation.
Mounting the wall version
Alignment
Mount the transmitter so that the probe points down.
Mounting variant 1
Drill the necessary holes using the drill template drawn on the
packaging. Then insert the plugs delivered with the device and
mount the transmitter with the screws.
Mounting variant 2
If there is a TS35 DIN top-hat rail available, the transmitter can be
clipped on to the top-hat rail directly with the help of the mounting
kit AC5002 (available as optional extra). For this, the DIN holders
(a kit has two holders and eight screws) are screwed directly on to
the predrilled holes in the transmitter.
Note: Unauthorised use of the menu can be prevented by locking the setting “Display Menu”
(using the HW4 software > Device Manager > Display).

Scaling / Adjustment / Firmware update
The following settings can be made with the help of the HW4 software and either the service cable
AC3006 or AC3009:
• new scaling of the outputs
• adjustment
• fi rmware update
You can fi nd a detailed description in the manual that you can download from our web site at
www.rotronic-humidity.com
Periodic calibration of the probe / transmitter
Both the Pt 100 RTD temperature sensor and the corresponding electronics are very stable and
do not normally need to be changed or calibrated after factory calibration.
The electronics of the transmitter do not normally require calibration in the fi eld. They can be
checked easily with the help of the probe simulator in the HW4 software package. The electro-
nics cannot be repaired in the fi eld and should be returned to the manufacturer in the case
of problems. For details on calibration, please see the full version of the instruction manual,
which you can download from the internet.

LEX TF52 / TF53 SERIES
Electrical installation
Power supply
a) TF52 (2-wire, current loop): 10 to 28 VDC – depending on the connected load.
The minimum supply voltage can be calculated as follows. V min = 10 V + (0.02 x load*)
*Load (resistance in Ohm). The minimum supply voltage for the maximum load of 500 Ohm is:
10 + (0.02 x 500) = 20 VDC. The maximum current consumption is 30 mA.
b) TF53 (3-wire with analogue outputs): 5 to 40 VDC or 5 to 28 VAC. The maximum current con-
sumption is 30 mA.

Programming
The basic settings of the devices are made in the factory according to your order. The transmit-
ters are adjusted in the factory and therefore do not need to be checked and readjusted during
installation. The devices can be started immediately after installation.
Display
In models with LC display the value can be read directly.
Caution: Wrong supply voltages and excessively high loading of the outputs can
damage the transmitter.
