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.

When the equipment is open you can set the baud rate by using the code switch F Fig. 3 (S 8 to 10). The baud rate of the temperature transmitter TRV 5-40 is set at our works to 250 kBit/s (for a max. cable length of 125 m). Reduce the baud rate if the cable length exceeds 125 m. Make sure that all bus nodes feature the same baud rate setting.
Note
The specified max. baud rates and cable lengths are based on empirical values ascertained by GESTRA. However for some applications it might be necessary to reduce the baud rate in order to ensure trouble-free operation.

Checking wiring
Before installation check the wiring:
n Are the temperature sensors wired according to the wiring diagram? n Is the wiring of all CAN bus devices in accordance with the wiring diagrams? n Is the polarity of the bus line always correct? n Are all the end-of-line devices of the bus line provided with a 120 Ω terminating resistor?
Applying supply voltage
Switch on supply voltage. The two seven-segment indicators are tested, which means that all segments and decimal points are flashing. The test is also carried out whenever the connector for the bus line is pulled out of the transmitter and then plugged in again.
Changing system configuration
The control units NRS 1-40.1 and NRS 1-40.2 associated with the temperature transmitter TRV 5-40 are designed for four limiting functions for monitoring liquid level and temperature. The level electrodes NRG 1x-40, NRG 1x-41.1 and the temperature transmitter TRV 5-40 are to be connected to the control unit NRS 1-40.1. The level electrode NRG 1x-41 and the temperature transmitter TRV 5-40 have to be connected to the control unit 1-40.2.
For the operation of the limiting system it is necessary to establish in the control unit the number of sensors with which the equipment has to work.
For more information see chapter “Commissioning” in the installation manual NRS 1-40.1 and NRS 1-40.2.
The following settings can be adjusted with the TRV 5-40:

System Malfunctions
Causes
Faulty installation and/or configuration of CAN bus components, excessively high temperatures in devices, defective electronic component parts or electromagnetic interferences of the supply system can result in system malfunctions.
Other malfunctions are:
n Incorrect communication in the CAN bus system n Overloading of the 24 V power supply unit that is integrated in the control unit
Note
Before carrying out the system malfunction analysis please check: Wiring:
Is the wiring in accordance with the wiring diagrams? Is the polarity of the bus lines always correct? Are the bus lines of the first and the last devices provided with 120 Ω terminating resistors?
Configuration of the level electrode NRG 1x-40 (Low water level LW): Are the wire bridges (equipment 1 or 2) set correctly? Does the position of the wire bridge correspond with the node ID setting?
Configuration of the temperature transmitter TRV 5-40: Is the temperature transmitter TRV 5-40 set correctly as equipment 1, 2, 3 or 4?
Node ID: Are all node ID settings correct? Note that no node ID setting must be used twice!
Baud rate: Does the baud rate setting correspond with the cable length? Is the baud rate setting of all devices identical?
18
System Malfunctions – continued –
Systematic malfunction analysis
The sources of malfunctions occurring in CAN bus systems operating with several bus-based stations must be analysed systematically since faulty components or incorrect settings can give rise to negative interactions with intact bus devices in the CAN bus system. These unwanted interactions can cause error messages in fully functional bus devices, which will make fault detection even more difficult.
We recommend the following systematic fault finding procedures:
Step 1 (Start)
Detach terminal strips in all sensing units of bus devices.
Level electrode Conductivity electrode Pressure sensor Temperature sensor etc.
Check
Use fault-finding list to correct fault(s)!
Final test: Have all faults been eliminated?
System Malfunction
Use fault-finding list to identify the fault(s).
Cut off power supply to the equipment!
Step 2
Plug in terminal strips of the sensing unit of a system e. g. NRS ... and NRG ... (electrodes)
Step 3
Apply mains voltage to bus devices of the system e. g. NRS ... and NRG ...
Check next system

Annex
CAN bus
All devices (level, conductivity) are interconnected via CAN bus. The CANopen protocol is used for the data exchange between the equipment groups. All devices have an electronic address – the node ID. The four-core bus cable serves as power supply and data highway for high-speed data exchange.
The CAN address (node ID) can be set between 1 and 123. The temperature transmitter TRV 5-40 has already been configured at our works for operation with
other GESTRA components and can be used straight away without having to set the node ID.

Node ID
Should it be necessary to establish other node IDs please take the interdependence of the equipment into consideration and assign the node ID for the individual group components according to the following table:
Control unit
NRS 1-40.1
X X + 1 X + 2 X + 3 X + 4 1 2 3* 4 5
Sensor 1

NRG 1x-40
as second device
Reserved area
Sensor 3
level electrode
NRG 1x-41.1
Note
The node ID 3* for the second level electrode NRG 1x-40 must be set in situ because the default factory setting is 2.
Changing node ID for safety part
When the housing is open: Use a thin blade screwdriver to set switches S1 to S7 of the code switch
table “Node ID”. Enter the adjusted node ID on the name plate.
Note
The two node IDs for the two actual value outputs (part for temperature monitoring and control) are linked with the node ID of the safety part and cannot be adjusted. For more information see the installation manual of the control unit TRS 5-40.
