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 Designation IV 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. 4

Explanatory Notes Scope of supply TRG 5-63, TRG 5-64, TRG 5-65, TRG 5-66, TRG 5-67, TRG 5-68 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. 5

Annex Decommissioning Disposal 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). 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. Declaration of Conformity We hereby declare that the temperature sensor TRG 5-6x conforms to the following European guidelines: LV guideline 73/23/eec version 93/68/eec EMC guideline 89/336/eec version 93/68/eec Pressure Equipment Directive (PED) 97/23/EC of 29 May 997 Applied conformity assessment procedure: Annex III, Module B and D, verified by the Notified Body 0525.
