Important Notes
Usage for the intended purpose
The temperature transmitter TRV 5-40 in conjunction with the temperature sensors TRG 5-63, TRG 5-64, TRG 5-65, TRAG 5-67 and TRG 5-58 must only be used for measuring temperatures.
Safety note
The equipment must only be installed and commissioned by qualified and competent staff. Retrofitting and maintenance work must only be performed by qualified personnel who – through
adequate training – have achieved a recognised level of competence.
PED (Pressure Equipment Directive)
The equipment fulfils the requirements of the Pressure Equipment Directive 97/23/EC and can be used with fluids of group 1 and 2. With CE marking.
ATEX (Atmosphère Explosible)
According to the European Directive 94/9/EC the equipment must not be used in explosion risk areas.

Description
The temperature transmitter TRV 5-40 is designed for the connection of three temperature sensors TRG 5-6x (platinum resistance thermometer Pt 100 to EN 60751). The temperatures measured by the temperature sensors are converted by the temperature transmitter TRV 5-40 and sent to the CAN bus in the form of a data telegram.
The data are transferred via CAN bus, using the CANopen protocol.

Description – continued –
The temperature transmitter TRV 5-40 can be used as:
n safety temperature monitor / limiter in conjunction with a temperature sensor type TRG 5-6x and
the control unit NRS 1-40.1 / NRS 1-40.2 and
n temperature monitor & limiter in conjunction with one or two temperature sensors TRG 5-6x and the
control unit TRS 5-40 or any other equipment that is approved for this application.
The equipment combination can be used for monitoring, limiting or control purposes in steam plants and (pressurised) hot water installations according to TRD and EN 12952 and EN 12953.
Function
The temperature transmitter TRV 5-40 consists of the safety part for temperature limiting and the part for temperature monitoring & control.
The safety part is connected with the temperature sensor. The temperature sensor detects the tem­perature and sends the measured values to the safety part of the temperature transmitter, where the measured values are recorded redundantly and monitored.
The adjustable temperature limit T indicated by the temperature transmitter. The temperature sensing element on the electronic insert monitors continuously the temperature inside the transmitter housing. An automatic self-testing routine checks every 10 seconds the safety and reliability of the functions of the temperature sensor and the detection of the measured values.
The actual temperatures, the exceeding of the adjusted temperature limit T periodic self test and the temperature inside the transmitter housing are sent as a data telegram via CAN bus to the control equipment NRS 1-40.1 / NRS 1-40.2.
Regardless of the safety part two additional temperature sensors TRG 5-6x can be used for tempera­ture monitoring & control in order to measure further actual temperature values. These readings are also sent as data telegrams via CAN bus and will be evaluated e. g. by the control unit TRS 5-40.

Installation
Temperature transmitter TRV 5-40
The temperature transmitter TRV 5-40 is designed for wall mounting. Screw the four fixing lugs supplied with the transmitter into the housing. You can now attach the equipment to the wall without having to open the housing cover.
Note
After mounting the housing you must:
n connect the temperature sensor, n set the temperature limit T n check and if necessary change the baud rate setting (see chapter “Wiring”) n check and if necessary change the system configuration (see chapter
“Commissioning”)
n check and if necessary change the node ID (see chapter “Annex”)
Check and if necessary change settings
