DIN RAIL MOUNTING

CAUTION
ENSURE THAT THE LOW-LEVEL COMPARTMENT WHERE THE READER IS MOUNTED IS SUFFICIENTLY VENTILATED TO PREVENT OVERHEATING. THE DEVICE MUST BE ELECTRICALLY GROUNDED FOR EMC COMPLIANCE.
The reader is designed for installation on a grounded 35 mm DIN rail. It could be mounted in two different positions to facilitate integration.
Using the fixing clip and the two screws provided, screw it onto the box enclosure according to the preferred orientation.
SENSeOR recommends mounting the device vertically with antennas output to the top.

READER EMPLACEMENT

The reader is intended to be installed in the low voltage compartment of the switchgear. The other electrical assets are recommended to be weather protected in an enclosed location.

The reader is required to be installed within a maximum distance of 10 meters from the antennas, corresponding to the maximum length of the antenna coaxial cable for SAW temperature sensors and partial discharge measurement.

RECOMMENDED SPACING
For connectors access, it is recommended to leave the minimum clearance for top and bottom panels of 5 cm (2 inches).

POWER
The reader power connector is a 2-pin male connector. This screw connector supports from 26 to 16 AWG wires (0.13 to 1.31 mm² section). For stranded conductor use connector ferrules on the termination.

INPUT POWER

The reader operates at 24VDC nominal with a total power consumption of 6 Watts maximum.
SENSeOR recommends the use of a DC power supply in the same low-voltage compartment as the reader. It is possible to run a DC power bus to power multiple readers from one DC power supply. However, this option requires a careful consideration of the wire diameter, AC/DC, and circuit breaker capabilities.
Power connections are recommended to be at a minimum of 16 AWG (1.31 mm² section).
If bussed power is being considered, the wire gauge must be selected to prevent excessive voltage drop between the DC power source and the reader that is electrically farthest from the source.
The following block diagram outlines the recommended power wiring for the reader with a 2-pole circuit breaker and an AC/DC power supply. Surge suppression devices can also be installed between the input line and the neutral only if higher safety rating is required.

RELAY OUTPUT
Output relay connections are recommended to be at 18 AWG (0.82 mm² section) to cover the entire voltage range.

INTERNAL BATTERY
SENSeOR reader has an internal 3VDC non rechargeable battery to keep the UTC date and the time in case of power down. Battery needs to be replaced if voltage value is under 2.1V.

It can be replaced only by authorized person using the following or an equivalent reference:

Battery replacement procedure

• Disconnect all the AMS01 reader connections (antennas, environmental sensor, relay, and power supply).
• Using a PZ1 screwdriver, disconnect the ground lug and remove the screw.
• Extract the reader from its location on the DIN rail.
• Remove the 4 screws from the front panel.
• Remove the electronic card from the enclosure.
• Identify and replace the CR2032 battery by carefully respecting its polarity.
• Reinsert the electronic card in the enclosure.
• Screw the front panel on the enclosure.
• Reposition the reader on its location on the DIN rail.
• Reconnect the ground lug with the corresponding screw.
• Reconnect all the AMS01 reader connections (antennas, environmental sensor, relay, and power supply).

WARNING
THERE IS A RISK OF EXPLOSION IF THE BATTERY IS REPLACED BY AN INCORRECT TYPE.
BE CAREFUL OF USED BATTERY IN ACCORDANCE WITH YOUR REGIONAL LEGAL INSTRUCTIONS.

COMMUNICATION CONNECTIONS

The components are used to connect Modbus devices, energy communication systems and industrial equipment with each other and to SCADA or cloud systems.
The reader could be connected to a network using RS485 Modbus-RTU or Ethernet Modbus-TCP.

CABLING FOR RS485 COMMUNICATION
SENSeOR recommends the use of shielded cable for the RS485 wiring, providing at least one twisted pair, one single line, and a drain wire. Although, a typical recommended cable has two twisted pair. The twisted pair provides DATA ± signals to each reader while the single line would be for D-COM, providing a low-impedance return for each reader.

BUS RESISTIVE TERMINATION

The RS485 bus needs to be terminated at each end with a 120 Ohms resistor when long stretches of cable are used. This ensures that the bus has the correct impedance.
However, if the bus length is less than 2% of its maximum (20 meters at 9 600 bauds), the termination resistor may be omitted.
In general, RS485 adapters and master bus provide the source impedance internally and should be located at one end of the bus. If not, use this pinout to cable the resistor.

BUS DATA RATE
The RS485 bus data rate is dependent on the bus cable length and the number of readers on the bus. In industrial environments, slower data communication rates are generally more reliable.

BUS LENGTH
Bus cable length has an impact on the overall data rates that can be achieved. A conservative rule for RS485 follows this equation:
Baud rate x cable length (m) < 10 x 106
A 9 600 bauds network would require a bus length less than (10 x 106 / 9 600) equals to 1 042 meters (about 3 400 feet). This is perfectly adequate for most substation installations.

NUMBER OF READERS

The more readers on the RS485 bus there are, the weaker the baud rate is. Baud rate must be adjusted to accommodate the electrical characteristics depending on the circuit.

The following table provides an example of recommended baud rate following the number of readers:

SENSeOR recommends connecting a maximum of 15 readers on a RS485 bus.

MODBUS-RTU DEFAULT CONFIGURATION

By default, the reader is configured with the following settings:

• Baud rate: 19 200
• Data bits: 8
• Parity: None
• Stop bits: 1

CABLING FOR ETHERNET COMMUNICATION

SENSeOR recommends the use of shielded Cat 5e SFTP cable for the Ethernet wiring.
Readers Ethernet network is provided by a fixed configuration more detailed below.
The IP address is defined by the last four digits of the product serial number printed on the side of the reader.

The connected computer must have an IP address in the range of ‘10.200.AA.BB’ subnet and with ‘255.255.0.0’ mask. To avoid any IP addresses conflict between the reader and the computer, ‘AA’ and ‘BB’ settings are recommended to be higher or to be equal to the value of ‘100’.

IMPORTANT
IN CASE OF COMMUNICATION TROUBLES WITH THE ‘AMS01 CONFIGURATION TOOL’ APPLICATION, CHECK THAT THE FOLLOWING COMMUNICATION PORTS ARE OPENED ON THE COMPUTER: ‘6560’, ‘5707’, ‘5709’ & ‘5710’.

ENVIRONMENTAL SENSOR CONNECTION

The SENSeOR environmental sensor provides humidity, ambient temperature and dew point measurements recommended to complement the partial discharges data. Connection of this environmental sensor must be done respecting cable colors and connector position.
Use 4-conductor 24 AWG (0.20 mm² section) shielded cable with 6-meter maximum length.

CONNECTING TO EARTH

Earth connections must be done using ground lug with a minimum of 16 AWG (1.31 mm² section) with ring terminal.

IMPORTANT
THE EARTH TERMINAL MUST BE PLACED BETWEEN THE NOTCHED WASHER AND THE SCREW HEAD.

CONNECTING RF ANTENNAS

Antenna installation should respect following pattern. Two antennas by compartment connected to the reader using A and B output connectors.

ANTENNA POSITIONING
Space antennas environment for at least 10 cm of metallic parts:

Place antennas of the same pair (‘A’ & ‘B’) on each side of the installed sensors:

• Align the antennas collinearly along the largest metal surface.
• The magnets used to attach the antennas must all be in direct contact with the metal surface:

SYSTEM INSTALLATION AND CONFIGURATION
