NOJA-565-07

1 Introduction The OSM recloser is supplied with an RC10 Control Cubicle. The Relay module inside the RC10 has 3 USB ports, one RS232 port and an Ethernet port (REL-02 only). Basic port settings can be made directly from the RC10 operator panel. Some advanced settings, however, can only be configured using NOJA Power’s Configuration and Management Software (CMS). This manual describes the wiring interfaces and setup information required to successfully configure a remote connection from a PC running CMS to the RC10 using one of the above ports. The RC10 can also be configured for the IEC or DNP3 protocol. Please refer to the relevant protocol manuals for details. Please note that the CMS protocol can be enabled with either DNP3 or IEC also enabled (using the same port if required) but the IEC protocol and DNP3 protocol cannot be enabled concurrently. The USB ports can be used with NOJA Power approved communications accessories only. The accessories can be used to provide a wide range of port interfaces such as RS485, Ethernet, GSM and GPRS modems. This document should be read in conjunction with the user manual supplied with the automatic circuit recloser and the relevant protocol definition document. Protocol documents are available from NOJA Power on request. A reasonable level of SCADA interface knowledge is required.

NOJA-565-07 6 External Communications Equipment The external load power source connection is located on the Switchgear Interface Module (SIM) in the RC cubicle and is labelled “External Supply 12Vdc OUT”. This power source can be used to power up external communications equipment such as modems and radios. Power to the SIM is provided by the Power Supply Module (PSM) which is powered directly from a step down Voltage Transformer or utility Low Voltage (LV) mains. The SIM module provides the power management for the RC10 and battery charger. When the AC supply is lost it switches over to the battery supply.

POWER IN

BATTERY IN 12Vdc OUT

The RC10 can be configured such that the radio or modem will be turned off after a set period of time when the AC power is lost, to conserve the backup battery power. The external load settings are located on the System settings screen in CMS.

24

NOJA-565-07

To set the external load time, enter a value in minutes from 0 – 1440 into the “External Load Time” text box in the UPS section. If set to zero (0), the external load will remain on. The external load can also be cycled off and back on again at regular intervals if the connected equipment requires a regular reset. To set the reset time enter a value in hours from 0 – 720 into the “External Load Reset Time” text box in the UPS section. If set to zero (0), the reset is disabled. Notes:  

External Load Time will only work if a Modem or Radio is configured. It will not work when using a direct connection. The “Modem is powered from external load” setting must be enabled for External Load Time to work.

6.1

External Load Power

A 12Vdc power supply for communications equipment is located on the SIM module. The External Load Output can be turned ON or OFF from the Panel or CMS software. Note: The external load output will indicate OFF when the external supply is shut-down due to AC supply External Load Time-out or low battery.

The power supply is rated at 12V 20W on average over a rolling 60 seconds window. The external load supply switches off immediately if the current exceeds 5.8A. The external power supply output is software managed to minimize the risk of overloading the power supply system. The output/overload protection mechanism is detailed below. Battery Supply above 11.0 V:

 

If the current is above 5.8 A for 25ms then the external supply will turn off immediately and stay off until the customer turns the external supply on again. The external supply will supply 20 W on average over a rolling 60 seconds window. So, for example, if the external load supplies 30W in the first 30 seconds then only 10W can be supplied over the next 30 seconds to ensure an overload does not occur as shown in Example 2 below. W 30W 20W 10W Time 60s

30s Example 1 W 30W 20W 10W

Time 30s

60s

Example 2



When the supply is turned off because of the power being exceeded, it will be reported in the event log as an external supply overload.

AC ON, Battery Supply below 11.0 V or disconnected: 

The external supply cannot draw more than 15W on average over a rolling 60 seconds window. If it does it will shut off within 10ms. The state will be reported in 26

NOJA-565-07

the event log as shutdown. When the supply shuts down under this condition it automatically turns back on when a battery supply of more than 11.6 volts is connected. Drawing more than 15W in this instance may cause the RC10 to shutdown and restart in some cases. AC OFF, Battery Supply below 11.0 V: 

6.2

The external supply is off.

Typical current draw for Radio Frequency (RF) output

When determining power consumption of radios the following need to be considered: Item

Definition

RF Output

Actual amount of power (in watts) of RF energy that the radio produces at its output. The RF output will depend on the specification of the radio and the antenna used.

Load consumption

Load consumption is the amount of power (in watts) that the radio needs to operate. The load consumption will vary depending on the RF output and whether the radio is transmitting or receiving. The method of transmission also affects the power consumption.

Tx supply current

Current drawn by the radio when transmitting.

To determine the load consumption, if for example a radio requires 2.5 amps to transmit with an RF output of 5W and the voltage is 12Vdc, then the load consumption is 2.5 amps x 12Vdc = 30W. Things to note:   

Some radios will draw more power than others. The radio manual should be consulted to confirm power requirements. After a short outage there are inrush currents which cause higher than normal load consumption. Transmission method can vary e.g. Frequency-shift keying (FSK) or Phase-shift keying (PSK). Note that some transmission methods require more power to operate.

NOJA’s external load power supply is rated at 20W on average over a rolling 60 seconds window. If for example a radio is set to transmit at 5W RF output then this will require approximately 30W power consumption. If we refer to section 7.1, one can see that this may cause the external load overload to occur as after supplying 30W for 30 seconds only 10W can be supplied for the next 30 seconds. If a greater RF output is required then it’s possible to use a more efficient antenna with a high gain. NOJA can also provide a High Power Radio Supply Kit which is suitable for radios that have a load consumption of up to 40W continuous. Please refer to NOJA-7114 High Power Radio Supply. The client should NOT, under any circumstances connect communications equipment to the backup battery as this can drain the battery, cause a system shutdown or damage the equipment. 27

NOJA-565-07 8 DNP3 Protocol Setup The DNP3 interface in the RC10 can provide DNP3 operation with a single master station or control centre using a serial channel or an Ethernet network. The DNP3 protocol implementation in the RC10 is described in detail in the relevant protocol definition document – NOJA-522-02 DNP3 Protocol Implementation. Please read this section in conjunction with this document. The CMS protocol is a proprietary protocol used for communications between the RC10 and the CMS configuration software (refer to Section 3 on how to configure a remote connection between a PC running CMS and the RC10).

8.1

Activating DNP3

To activate the DNP3 protocol, select “DNP3” from the Protocol Type drop-down box. CMS allows the user to modify a wide range of settings including the actual DNP3 mapping. To configure DNP3 click the “Protocol Settings” button.

Link Layer, Application Layer and Unsolicited Response settings are configured on the “General” tab. These settings are described in the DNP3 protocol implementation manual. DNP3 mappings are configured on all the other tabs. Refer to the DNP3 protocol implementation manual for more information. The “Reset to default” button restores all DNP3 settings to default. The “Test” button checks all the DNP3 mappings on each tab (except for General) and reports any conflicts.

37

NOJA-565-07

8.2

DNP3 Interface Management

The RC10 DNP3 interface is intended for use with a single DNP3 master station with a single set of event buffers interfaced through a single communications port (either serial or Ethernet). In general, it is recommended that it is only used in this manner. In particular the user should note:   



Operation over redundant paths is dependent on the master station’s capabilities. There is no configuration that permits “normal” DNP3 event polling operation to be performed concurrently from more than one master station or control centre without errors. A restricted subset of DNP3 operations with multiple different master stations is possible, but care must be taken to ensure that event reporting functions are either not used, or are only used very selectively. This is not “normal” DNP3 usage and may require specific configuration settings to be made in both the masters and in the RC10 in order to avoid errors. A very high level of understanding of the modes of operation of DNP3 may be required in order to correctly configure a multi-master system in such a manner as to avoid errors.

For more details please refer to NOJA 7230 DNP3 Interface Management.
