1 Safety notes
Safe and secure operation of the DIN rail transmitter can only be guaranteed if the
operating instructions and all safety notes are read, understood and followed.
1.1 Designated use
Designated use • The unit is a universal, presettable temperature transmitter for resistance thermometer (RTD),
thermocouple (TC) as well as resistance and voltage sensors. The unit is constructed for mounting
on a DIN rail.
• The manufacturer cannot be held responsible for damage caused by misuse of the unit.
• Separate Ex documentation is part of this operating manual, for measurement systems in hazardous areas. The installation conditions and connection values
indicated in these instructions must be followed!
1.2 Installation, commissioning and operation
Installation, commissioning and operation
The unit is constructed using the most up-to-date production equipment and complies to the safety
requirements of the local guidelines. The TMT122 temperature transmitter is fully factory tested
according to the specifications indicated on the order. However, if it is installed incorrectly or is
misused, certain application dangers can occur. Installation and wiring of the unit must only be done
by trained, skilled personnel who are authorized to do so by the plant operator. This skilled staff
must have read and understood these instructions and must follow them to the letter. The plant
operator must make sure that the measurement system has been correctly wired to the connection
schematics. Due to its construction, the transmitter cannot be repaired. When disposing of the DIN
rail transmitter, please take note of the local disposal regulations.
Electrical temperature sensors such as RTD's and thermocouples produce low-level signals proportional to their sensed temperature. The TMT122 temperature transmitter converts the low-level
sensor signal to a standard 4 to 20 mA DC signal that is relatively insensitive to lead length and electrical noise. This current signal is then transmitted to the control room via two wires.
The transmitter can be commissioned before or after installation. It may be useful to commission it
on the bench, before installation, to ensure proper operation and to become familiar with its functionality. Make sure the instruments in the loop are installed in accordance with intrinsically safe or
non-incendive field wiring practices before connecting a HART
®
communicator in an explosive
atmosphere.
The printed circuit board of the transmitter is protected by the DIN rail housing, resisting moisture
and corrosive damage. Verify that the operating atmosphere of the transmitter is consistent with the
appropriate hazardous locations certifications.
#
Warning!
Electrical shock could cause death or serious injury. If the sensor is installed in a high voltage environment and a fault or installation error occurs, high voltage may be present on the transmitter leads
and terminals.
SAFETY INSTRUMENTED SYSTEMS (SIS)
Third party validated metrics are available for the TMT122 temperature transmitter. Testing is done
per IEC 61508 for Safety Instrumented Systems. The safety manual can be ordered separately under
order code:
SD007R09EN.

Caution!
Switch off power supply before opening housing cover of the temperature sensor. Do not install or
connect the unit to power supply before the sensor is connected to the transmitter. If this is not followed, parts of the electronic circuit will be damaged.
4.2.1 Sensors
Connect the sensor cables to the respective DIN rail transmitter terminals (Terminals
3 to 6) by following the wiring diagram (see fig. 5). Wiring plugs are removable for easy access.
4.2.2 Output signal and power supply
Connect the cable wires from the power supply to terminal 1 and 2 according to the wiring diagram
(see fig. 5). For convenient installation, the connection is designed as a removable plug, so the connection can be made on the terminals, then plug in the connection socket to the transmitter housing.
!
Note!
The screws on the terminals must be screwed in tightly.
4.2.3 HART® connection
Connection is made directly at the communication socket 7 and 8 at the front wall of the transmitter. The sockets are inside the loop to a power supply or barrier. In order to connect the transmitter
in a hazardous area, please read the separate Ex documentation.
!
Note!
The measurement circuit must have a load of at least 250 Ω. If using the E+H power
supplies RNS 221 and RN 221N, this resistance is already installed in the unit and is therefore not
required externally (see fig. 6, and see fig. 7)!
