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.
