Safety notes TMT162

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
Hazardous areas
When installing the unit in a hazardous area, the national safety requirements must be met. Make
sure that all personnel are trained in these areas. Strict compliance with installation instructions and
ratings as stated in this documentation is mandatory.
The measurement system fulfils the safety requirements according to EN 61010 and the EMC
requirements according to EN 61326 as well as NAMUR NE 21, NE 43 and NE 89
recommendations.
#Warning!
The TMT162 must be powered by a 11 to 40 V DC power supply with a limited power according
to NEC Class 02 (low voltage, low current) limited to 8 A and 150 VA in case of a short circuit.
Technical advancement
The manufacturer reserves the right to modify technical data without prior notice. Your distributor
can supply you with current information and updates to these Operating Instructions.
1.4 Returns
Please follow the Return Authorization Policy.
