Chapter 1

Overview

Introduction The Allen-Bradley 865 differential protection system includes all the

essential protection functions needed to protect transformers for distribution networks of utilities, industry, power plants and offshore applications as well as motor and generator differential protection. Further, the device includes several programmable functions, such as thermal and circuit breaker protection and communication protocols for various protection and communication situations. An optional arc flash protection feature is also available.

The Allen-Bradley 865 can be used for selective differential

overcurrent, short-circuit protection of generators, transformers and motors in solidly or impedance earthed power systems. The relay can also be used for single, two or three-phase overcurrent and/or sensitive earth fault protection.

The modern technology in association with an extensive self-

supervision system and a reliable construction ensures extremely high system availability for the Allen-Bradley 865 protection relay.

Main Relay Features The main features of Allen-Bradley 865 are:

• Fully digital signal handling with a powerful 16-bit

microprocessor, and high measuring accuracy on all the setting ranges due to an accurate 16-bit A/D conversion technique

• Wide setting ranges for the protection functions, e.g. the earth

fault protection can reach a sensitivity of 0.5%

• The device can be matched to the requirements of the application

by disabling the functions that are not needed

• Flexible control and blocking possibilities due to digital signal

control inputs (DI) and outputs (DO)

• Easy adaptability of the relay to various substations and alarm

systems due to flexible signal-grouping matrix in the relay

• Freely configurable display with six measurement values

User Interface

The relay can be controlled in three ways:

• Locally with the push-buttons on the relay front panel

• Locally using a PC connected to the serial port on the front panel

or on the rear panel of the relay (both cannot be used simultaneously)

• Via remote control over the remote control port on the relay rear

panel.

Operating Safety

A T T E N T I O NA T T E N T I O N

The terminals on the rear panel of the relay may carry dangerous voltages, even if the auxiliary voltage is switched off. A live current transformer secondary circuit must not be opened. Disconnecting a live circuit may cause dangerous voltages! Any operational measures must be carried out according to national and local handling directives and instructions.

Carefully read through all operation instructions before any

operational measures are carried out.

Local Panel User Interface 2-5

Resetting Latched Indicators and Output Relays

All the indicators and output relays can be given a latching

function in the configuration.

There are several ways to reset latched indicators and relays:

• From the alarm list, move back to the initial display by pushing

the CANCEL key for approx. 3 s. Then reset the latched indicators and output relays by pushing the ENTER key.

• Acknowledge each event in the alarm list one by one by pushing

the ENTER key equivalent times. Then, in the initial display, reset the latched indicators and output relays by pushing the ENTER key.

The latched indicators and relays can also be reset via a remote

communication bus or via a digital input configured for that purpose.

Adjusting Display Contrast

The readability of the LCD varies with the brightness and the

temperature of the environment. The contrast of the display can be adjusted via the PC user interface, and SetPointPS software.

Local Panel Operations The front panel can be used to control objects, change the local/

remote status, read the measured values, set parameters, and to configure relay functions. Some parameters, however, can only be set by means of a PC connected to one of the local communication ports. Some parameters are factory-set.

• Status – The stage is not detecting any fault at the moment. The stage can also be forced to pick-up or trip if the operating level is "Configurator" and the force flag below is on. Operating levels are explained in section “Operating Levels”.

• SCntr 5 – The stage has picked-up a fault five times since the last reset of restart. This value can be cleared if the operating level is at least "Operator".

• TCntr 1 – The stage has tripped two times since the last reset of restart. This value can be cleared if the operating level is at least "Operator".

• SetGrp 1 – The active setting group is one. This value can be edited if the operating level is at least “Operator”. Setting groups are explained in section “Setting Groups”.

• SGrpDI – The setting group is not controlled by any digital input. This value can be edited if the operating level is at least “Configurator”.

• Force Off – The status forcing and output relay forcing is disabled. This force flag status can be set to “On” or back to “Off” if the operating level is at least “Configurator”. If no front panel button is pressed within five minutes and there is no SetPointPS communication, the force flag will be set to “Off” position. The forcing is explained in section “Forced Control (Force)”.

Setting Groups

Most of the protection functions of the relay have two setting groups.

These groups are useful for example when the network topology is changed frequently. The active group can be changed by a digital input, through remote communication or locally by using the local panel.

The active setting group of each protection function can be selected

separately. Figure 2.11 shows an example where the changing of the I> setting group is handled with digital input one (SGrpDI). If the digital input is TRUE, the active setting group is group two and correspondingly, the active group is group one, if the digital input is FALSE. If no digital input is selected (SGrpDI = -), the active group can be selected by changing the value of the parameter SetGrp.

Figure 2.11 – Example of Protection Submenu with Setting Group

The changing of the setting parameters can be done easily. When the

desired submenu has been found (with the arrow keys), press the ENTER key to select the submenu. Now the selected setting group is indicated in the down-left corner of the display (See Figure 2.12). Set1 is setting group one and Set2 is setting group two. When the needed changes, to the selected setting group, have been done, press the LEFT or the RIGHT key to select another group (the LEFT key is used when the active setting group is 2 and the RIGHT key is used when the active setting group is 1).

Fault Logs

All the protection functions include fault logs. The fault log of a

function can register up to eight different faults with time stamp information, fault values etc. Each function has its own logs (See Figure 2.13).

Figure 2.13 – Example of Fault Log

To see the values of, for example, log two, press the ENTER key to

select the current log (log one). The current log number is then indicated in the down-left corner of the display (See Figure 2.14, Log2 = log two). The log two is selected by pressing the RIGHT key once.

Operating Levels

Local Panel Operations (cont.)

The relay has three operating levels: User level, Operator level

and Configurator level. The purpose of the access levels is to prevent accidental change of relay configurations, parameters or settings.

USER level

Use: Possible to read e.g. parameter values,

measurements and events Opening: Level permanently open Closing: Closing not possible

OPERATOR level

Use: Possible to control objects and to change e.g. the

settings of the protection stages Opening: Default password is 1 Setting State: Push ENTER Closing: The level is automatically closed after 10 minutes

idle time. Giving the password 9999 can also close

the level.

CONFIGURATION level

Use: The configurator level is needed during the

commissioning of the relay. E.g. the scaling of the

voltage and current transformers can be set. Opening: Default password is 0002 Setting State: Push ENTER Closing: The level is automatically closed after 10 minutes

idle time. Giving the password 9999 can also close

the level.

865-UM001A-EN-P – July 2009

Local Panel User Interface 2-15

Opening Access

1. Push the INFO key and the ENTER key on the front panel.

ENTER PASSWORD

***

Figure 2.15 – Opening the Access Level

2. Enter the password needed for the desired level: the password can contain four digits. The digits are supplied one by one by first moving to the position of the digit using the RIGHT key and then setting the desired digit value using the UP key.

3. Push the ENTER key.

Password Handling

The passwords can only be changed using SetPointPS software

connected to the local RS-232 port on the relay.

It is possible to restore the password(s) in case the password is lost or

forgotten. In order to restore the password(s), a relay program is needed. The serial port settings are 38400 bps, 8 data bits, no parity and one stop bit. The bit rate is configurable via the front panel.

Command Description

get pwd_break Get the break code (Example: 6569403) get serno Get the serial number of the relay (Example: 12345)

Send both the numbers to Rockwell Automation and ask for a

password break. A device specific break code is sent back to you. That code will be valid for the next two weeks only for this specific device.

Command Description

set pwd_break=4435876 Restore the factory default passwords (“4435876” is

just an example. The actual code should be requested from Rockwell Automation.)

Now the passwords are restored to the default values (See section

“Operating Levels”).
