1. Description

The Wireless Controllers REC601/603 are

compact, solution based devices for the remote

control and monitoring of secondary substations

such as network disconnectors, load break

switches and Ring Main Units (RMU’s) in

distribution networks.

The Wireless Controllers REC601/603 enable the

SCADA system to wirelessly monitor and control

the field devices over the public communication

infrastructure (GPRS).

The Wireless Controllers REC601/603 utilize the

built-in GPRS features for reliable and secure end-

to-end communication providing remote

monitoring and control of a single object with

Wireless Controller REC601, or up to three (3)

objects with Wireless Controller REC603.

The use of Wireless Controllers REC601/603 in

distribution networks improves the quality of

power distribution and dramatically reduces the

outage time in affected areas. The areas directly

adjacent to these affected areas would also show

reduced outages and overall effects. It also

reduces the capital expenditures in the

distribution network by limiting the replacement of

legacy devices and contributes to more direct

cost savings by facilitating preventative

maintenance. Wireless Controllers REC601/603

are also ideally suited to be retrofitted to existing

disconnectors and thus enabling remote control

of these devices and further extending the life

cycle of the disconnector itself.

2. Applications

The Wireless Controllers REC601/603 are

important and powerful components in an

automated distribution network. Connected to the

central control system (SCADA/DMS) – that

manages the utility network - they serve as the

core of the secondary substation automation

system. These devices are recommended devices

for multiple disconnector or distribution

transformer applications in distribution networks

that require specifications and/or features like

listed below.

• Highly reliable control and monitoring of up to

three (3) objects (per REC603):

LEDs

– Separate LED indicators for earthing status

– Supports both local and remote disconnector

control

– More than one Wireless Controller

REC601/603 can be connected in a single

location to facilitate the Ethernet enabled

control and monitoring of more than three (3)

disconnectors

• Overload protection of actuator motors

– Load current measured in the motor circuit

– Measurement of object transition time

– Energy limit based motor overload protection

(“software fuse”)

• Always on two-way communication based on

GPRS via an M2M gateway

– Redundant IEC 60870-5-104 connections

provide extra availability

– Communication monitoring and automatic

connection re-establishment

– High level data security through internal VPN

and Firewall

– Possibility to act as an IEC 60870-5-101

master (router) for another communicating

sub-device (for example metering unit or fault

passage indicator)

• Built-in battery charger with advanced battery

control:

– Temperature compensated charging

– Battery monitoring/testing (condition

monitoring)

– Deep discharge protection

• Heater control to limit effects of ambient

temperature variations, such as condensation,

etc.

• Real-time clock for accurate event time-tagging

• Robust aluminium casing design for easy DIN

rail mounting

3. Battery condition monitoring

The Wireless Controllers REC601/603 are

equipped with condition based functionality that

make the conditioning monitoring of the built-in

battery of the device possible and optimize the

lifetime and maintenance intervals of the back-up

batteries in the control assembly.

The back-up battery could periodically (scheduled

by operator) be tested by switching off the

charger and switching on the dummy load.

Current and voltage measurements are taken for

a defined period of time (discharging time period).

Based on these measurements of the battery’s

current and voltage levels, an assessment is

made regarding the battery’s condition and

remaining operational capacity (in Ah). If the

assessment shows that the battery has a

significant depletion in capacity an IEC

60870-5-104 alarm event would then be

generated in the system.

Also the Wireless Controllers REC601/603 feature

the ability to protect the battery against complete

discharge. This is achieved by the fact that the

battery voltage is always measured in network

fault conditions (primary power source is

disconnected). If the measured battery voltage

level is below a defined limit (assumed as a

“battery failure”) an IEC 60870-5-104 alarm event

would then be generated in the system and the

load is disconnected from the battery.

4. Motor overload protection

The Wireless Controllers REC601/603 are

equipped with condition based functionality that

assists in the monitoring and management of the

disconnector motor by using over current

detection and shut down of the motor that is

connected to the device.

The over current detection is initialized as soon as

a switch-on command is received by the motor.

This overload detection process is based on

measurements done by a Hall-Effect Current

Transducer (optional accessory) for load current

and control duration measurements. As soon as a

predefined energy limit is exceeded, as shown by

the mentioned measurements, the motor is shut

down by disconnecting it via the relay output on

the Wireless Controllers REC601/603.

5. Inputs and outputs / Physical interfaces

The Wireless Controllers REC601/603 are

equipped with numerous input and output

connections to manage control operations that

are communicated via the wireless (GPRS)

capabilities of the devices.

Wireless Controller REC603 has 16 binary inputs

(REC601 has 6) for monitoring and alarms, and 7

binary outputs for disconnector control (REC601

has 3). Both REC601 and REC603 devices each

have 2 binary outputs and 2 analog inputs for

battery control within the ranges of 0-30 V, 0-10

A. Further both the devices each have a binary

output for over current motor control as well as

an analog input for motor control within the range

0-15 A.

Additionally the devices are equipped with a

transducer input and heater control output.

The Wireless Controllers REC601/603 also has

two serial ports (with DIP switches for serial port

2 hardware configuration) and an Ethernet

connector for communication and data transfer.

Also there is a SIM card insertion slot with SIM

card tray and antenna connector.

The status of the operational system is shown by

various groupings of LED light indicators. More

detailed information can be sourced via the

supported WebHMI.

Front panel LEDs

The Wireless Controllers REC601/603 are

equipped with 8 (eight) groups of LEDs indicating

the complete operational status of the device.

They are located on the device’s front panel and

are identified by accompanying labels.
