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.

(“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.
