1 Safety notes
Safe and secure operation of the field transmitter can only be guaranteed if the operating instructions
and all safety notes are read, understood and followed.
1.1 Designated use
• The unit is a universal, presettable temperature field transmitter for resistance temperature
detectors (RTD), thermocouple (TC) as well as resistance and voltage sensors. The unit is
constructed for mounting in field applications.
• 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
The unit is constructed using the most up-to-date production equipment and complies with the
safety requirements of the local guidelines. The 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, wiring and maintenance 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.
Electrical temperature sensors such as RTD's and thermocouples produce low-level signals
proportional to their sensed temperature. The 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 transmitter electronics module is permanently sealed within the 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 temperature field transmitter. Testing is done per
IEC 61508 for Safety Instrumented Systems. The safety manual can be separately ordered under
order code: SD005R09EN.
For more details and download see:
www.us.endress.com
Temperature Effects
The transmitter will operate within specifications for ambient temperatures between -40 and
+185 °F (-40 and +85 °C) without display. Heat from the process is transferred from the
thermowell to the transmitter housing. If the expected process temperature is near or beyond

TMT162 Safety notes
Endress+Hauser 5
specification limits, consider the use of additional thermowell lagging, and extension nipple, or a
remote mounting configuration to isolate the transmitter from the process.
1.3 Operational safety

4.2 Connecting the sensor
!Note!
For sensor connection terminal layout please see Fig. 5. On two sensor inputs the following
connection combinations are possible:
There are special cable entries available as accessories when connecting 2 sensors (not for XP
instrumentation). These can be found in chapter 9.4.
"Caution!
When connecting 2 sensors ensure that there is no galvanic connection between the sensors (e.g.
grounded duplex thermocouples). The resulting equalizing currents distort the measurements
considerably. In this situation, the sensors have to be galvanically isolated from one another by
connecting each sensor separately to a field transmitter. The device provides sufficient galvanic
isolation (> 2 kV AC) between the input and output.
4.3 Connecting the measuring unit
"Caution!
• Switch off power supply before installing or connecting the device. Failure to observe this may
result in destruction of parts of the electronics.
• If the device has not been grounded as a result of the housing being installed, grounding it via one

4.5 Degree of protection
The device conforms to the requirements to NEMA 4X (IP 67) ingress protection. In order to fulfil
an NEMA 4X (IP 67) degree of protection after installation or service, the following points must be
taken into consideration (also see Fig. 8):
• The housing seals must be clean and undamaged before they are replaced in the sealing rebate. If
they are found to be too dry, they should be cleaned or even replaced.
• All housing screws and covers must be tightened.
• The cables used for connection must be of the correct specified outside diameter (e.g. M20 x 1.5,
cable diameter from 0.315 to 0.47 in; 8 to 12 mm).
• Tighten cable gland or NPT fitting.
• Loop the cable or conduit before placing into the entry ("Water sack"). This means that any
moisture that may form cannot enter the gland. Install the device so that the cable or conduit
entries are not facing upwards.
• Entries not used are to be blanked off using the blanking plates provided.
• The protective cable gland must not be removed from the NPT fitting.

5.3.4 Command classification in the HART®protocol
The HART®protocol makes it possible for configuration and diagnostic purposes to transmit
measured and device data between the HART®master and the respective field device.
HART®masters such as the handheld module or PC-based operating programs (e.g. FieldCare)
require so-called device description files (DD = device descriptions, DTM), these make it possible
to access all information in a HART®device. Transmission of such information is done exclusively
using "commands".
There are three command classifications:
• Universal commands
Universal commands are supported and used by all HART®devices. Combined are for example
the following functionality:
– Recognizing HART®devices
– Readout of digital measured values
• Common practice commands:
These general commands offer functions that are supported or used by some but not all field
devices.
• Device specific commands
These commands enable access to device specific functions that are not HART®standardized.
Such commands access, among other things, individual field device information.
!Note!
Chapter 6.4.2 contains a list of all HART®commands supported.
