Important Notes
Usage for the intended purpose
Use temperature sensors TRG 5-63, TRG 5-64, TRG 5-65, TRG 5-66, TRG 5-67 and TRG 5-68 only in conjunction with temperature transmitter TRV 5-40 for measuring temperatures.
The equipment must only be used within the admissible pressure and temperature ratings.
Any type of use differing from the usage described above must be considered as improper. The resulting
risk will have to be borne by the user alone. The manufacturer hereby expressly rejects any claims for any
damage resulting from improper usage.
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 staff who - through adequate training - have
achieved a recognised level of competence.
Danger
The temperature sensors TRG 5-63 or TRG 5-64 are screwed into vessels or pipes. When
loosening the temperature sensor steam or hot water might escape!
This presents the risk of severe scalding all over the body!
Dismantle the temperature sensor only if the vessel pressure is verified to be 0 bar.
The temperature sensor becomes hot during operation. Touching the hot equipment
presents the risk of severe burns to hands and arms. All installation, removal and maintenance work must only be performed when the system is cold.
Classification pursuant to article 1 of the Pressure Equipment Directive (PED)
Category IV
Designation Safety accessory
CE marking CE 0525
ATEX (Atmosphère Explosible)
According to the European Directive 94/9/EC the equipment must not be used in explosion risk areas.

1 Temperature sensor
1 Installation manual
System description
The TRG 5-6x are temperature sensors with integrated platinum resistance thermometers Pt 100 to
EN 60751. The temperatures sensed by the temperature sensor are converted by the temperature transmitter TRV 5-40 and provided as a data telegram on the CAN bus.
The CANopen protocol is used for the data transfer via CAN bus.
The temperature sensor can be used as a measuring sensor for
■
a safety temperature control monitor/limiter in conjunction with temperature transmitter TRV 5-40 and
the switching controller NRS 1-40.1 and
■
as sensor for a temperature limiter/controller in conjunction with temperature transmitter TRV 5-40 and
the control unit TRS 5-40.
The equipment combinations can be used as controls, monitors or limiters in steam boilers and (pressurised) hot water installations to TRD and EN 12952 and EN 12953.
Function
The temperature sensors TRG 5-63, TRG 5-65, TRG 5-66 and TRG 5-67 feature one integrated platinum
resistance thermometer Pt 100 each.
The temperature sensors TRG 5-64 and TRG 5-68 are equipped with two platinum resistance thermometers Pt 100 for the connection of additional indicating equipment.
The resistance value of these thermometers changes as a defined function of the temperature.
The resistance thermometer is supplied with a constant current by the temperature transmitter and the
voltage generated by the changing of the resistance value is measured and processed in the transmitter.

Check wiring
Check that the temperature sensor TRG 5-6x and its associated temperature transmitter TRV 5-40 have
been wired in accordance with the wiring diagram (see page 15).
Apply mains voltage
1. Apply mains voltage or bus supply voltage to the control unit NRS 1-40.1.
Measure fluid temperature
Use the following table to ascertain the current temperature of the fluid, using the resistance value of the
Pt 100.
1. Take cover off the terminal box.
2. Connect test cable directly to the measuring element .

Malfunctions
Fault finding list for troubleshooting
Switchpoint "MAX temperature" not yet exceeded - but a MAX temperature alarm is raised
Fault: The temperature sensor is defective.
Remedy: Check whether the temperature sensor (Pt 100) gives correct readings. (Basic values of the
precision resistors according to DIN 43760 for Pt 100). In case of incorrect readings replace
the measuring element of the temperature sensor.
If faults occur that are not listed above or cannot be corrected, please contact our service centre or
authorized agency in your country.

Decommissioning
Danger
Risk of severe burns and scalds to the whole body!
Before removing the temperature sensor make sure that the vessel or the pipe are depressurised (0 bar) and cooled down to room temperature (20°C).
Disposal
Dismantle the temperature sensor and separate the waste materials, using the material specification as a
reference. Electronic component parts such as the circuit board must be disposed of separately! For the
disposal of the temperature sensor observe the pertinent legal regulations concerning waste disposal.
