1 - Introduction Actaris proposes a new technical solution to provide new possibilities for remote/local reading of the Corus. A new optional board with two independant RS485 ports offers increased communication capabilities with modems, RTUs, and gas chromatographs (future option). The RS485 board can be used in hazardous area and up to 4 Corus can be connected to the same modem (or RTU or gas chromatograph). The distance between the modem (or RTU) in safe area and the Corus depends on the number of Corus (1 to 4) and the electrical characteristics (linear L,C) and is at least 200m. The user can select the speed and other communication parameters for each of the two ports, including the choice of the protocol (Modbus or I-Flag). Hazardous Area

All devices on the same RS485 bus must have the same speed and data format. Commissioning of the RS485 board is very simple and retrofit (addition of an RS485 board on an existing Corus) is possible on site. All communication ports of Corus (optical, RS232, two RS485) can be used simultaneously without restriction.

2 - Technical description 2-1: Main characteristics: • ATEX internal board with two independant RS485 ports • ATEX compatibility with a maximum of 4 Corus connected on the same RS485 bus and a distance of 200m with the IS interface • Connection on the optional slot (J3 - CPU board) • Two wires passive RS485 ports half-duplex • Simultaneous communication on all ports without restriction • Configurable speed up to 38400 bauds • Configurable protocol (Modbus RTU and/or I-Flag) 2-2: Conditions of use: The board can be used when Corus is powered by battery or external power supply. When powered by battery, the calculation of the autonomy doesn’t change compared to a Corus without the optional board and should be based on communication time (for more details in chapter “8.4.3 Autonomy” of Corus user’s guide). The two ports are passive meaning that the ports must be powered by the intrinsic safety interface that will be connected on the Corus through the RS485 ports. Each port is isolated separately and can be connected to two different materials (modems, RTUs, PCs, etc). Suggested intrinsic safety interfaces are: • ISB+ for RS485 signal or • •

the barrier Z961 (from Pepperl&Fuchs) for data signals the BXNE31 (from Georgin) power supply for powering the port.

A separate power supply and barrier (or ISB+) must be used for the second port. Depending on the cables, interfaces, and the number of Corus on the RS485 bus, the ATEX classification (IIC, IIB or IIA) of the Corus can change. More details on maximal allowed parameters can be found in chapter 6. The classification with a single Corus and the above mentioned material (Z961 interface and BXNE31 power supply) remains IIC.

Note 1: The values provided in this table correspond to typical values in average conditions of use; They are calculated with a 30% margin to take into account the possible variations of operating conditions that could impact the consumption of the product (temperature, humidity, selfdischarge of the battery, …) Note 2: The frequency of retransmissions indicated in the table corresponds to average frequency on the two outputs, when both channels are configured for pulses. Note 3: In case of activation of digital output as ALARM output, the consumption of the device can be impacted, specially in “Standard” mode for which the output is activated as long as the alarm is active. Then, it is recommended to use preferably the ‘limited’ mode or to use CORUS with an external power supply module if “Standard mode” is required.

6 – Safety Instructions 6– 1: General The Corus with the RS485 optional board has the ATEX certification and is approved according to 94/9/CE directive related to introduction of material in explosive atmosphere area. The respect of this directive is mandatory and is now included in the ‘CE’ marking.

6 – 2: Marking related to ATEX The Corus equipped with its internal RS485 board is approved as category 1 equipment and is then suitable for use in zone 0 (areas with permanent presence of gas in normal operation) The corresponding marking is : 0081 LCIE 03 ATEX 6165X

II 1G EEx ia IIC T4

The ambient temperature range for operation is : -25°C ; +55°C The following label is placed on the flat cable of the optional board: CORUS RS485 ATEX BOARD

LCIE 03 ATEX 6165X

6– 3: Specific safety instructions •

The connectors J1 and J3 of the RS485 board can be connected only to RS485 bus.

•

Plug first the RS485 board into the Corus, before connection to the IS interface. Concerning bus cable, connect first the Corus side and finally as last action, connect the bus cable on IS interface side.

•

When equipped with the RS485 board, the classification of the whole material is suitable for use in zone 0. The classification to Group IIC, IIB or IIA will depend from the interface and the cables that will be connected on RS485 ports. See electrical parameters for each case in ATEX certificate variation. The user is responsible for the compatibility of the material that will be connected on the RS485 ports and must check the compatibility with electrical parameters of Corus and put the suitable marking on the products.

Actaris did calculate the compatibility for two typical cases: Case A: 1 Corus + BXNE31 + Z961 Case B: 4 Corus + BXNE31 + Z961

: :

Classification IIC Classification IIB

For the case B with 4 Corus one RS485 boards of each Corus is connected to the unique Z961 and to the unique BXNE31. •

Cable length between the Corus and the RS485 IS (intrinsic safe insulating) interfaces has an impact on the ATEX certification. The linear L and C of the cables multiplied by the length of the cable must be added to the parameters of the IS interface to evaluate the compatibility with electrical parameters defined in the ATEX certificate. The length of the cable between the IS interface and the PC or the RTU has no impact on ATEX compatibility. The above calculations (A and B cases) have been made with 200m cables between each Corus and the Z961. The table below gives for the two cases the maximal linear L of the cable and the maximal linear C:

Case A B

Max linear L (µH/m) 4.5 20

Cable length 200m 200m

Max linear C (nF/m) 4.75 121

•

It is recommended (but not mandatory) to use a shielded cable for connection to the RS485 line. The diameter for this cable has to be lower than 6mm (optimized is 5,5 mm) and it has to be passed through the black gland of the Corus.
