Sel SEL-2243 User manual

Schweitzer Engineering Laboratories, Inc. SEL-2243 Data Sheet

Every SEL Axion®node requires at least one SEL-2243 Power Coupler module. The SEL-2243 serves two purposes in

an Axion system:

1. It is the power supply for all modules installed in the node, and;

2. It provides two dedicated EtherCAT®ports so that multiple Axion nodes can operate together.

Power Supply Operation

One SEL-2243 has sufficient power capacity to accom-

modate an entire Axion node. The terminal strip at the

bottom of the unit, as seen in Figure 1, is the connection

point for incoming power. All Axion modules have a

55-position IEC C-style connector that provides a com-

munications and power interface to the backplane. The

SEL-2243 provides power to the node via the backplane

connector.

The power coupler module uses the same power supply

design that you would find in SEL protective relays. The

Axion provides test-proven superior performance and

availability, while also allowing for redundant power

couplers in a node for applications that need these. If you

install two power couplers in a node, both modules

actively share load and provide the necessary power for

node functions. If one SEL-2243 becomes unavailable,

there is zero switching delay or power loss to the node.

EtherCAT Operation

Each SEL-2243 provides two dedicated ports for Ether-

CAT networks. The ports will either be standard

10/100BASE-T or optional 100BASE-FX Ethernet ports.

EtherCAT is a real-time fieldbus protocol (see

Appendix E in the ACSELERATOR RTAC SEL-5033

Instruction Manual) that we can use to connect an RTAC

to I/O modules in an Axion system. If the installation has

only one node, then the backplane transmits EtherCAT

messages. Alternatively, if you use an SEL-3530 RTAC,

or if you need more I/O than will fit in a node, then the

ports on a power coupler module provide a mechanism

for extending the EtherCAT network through the use of

dedicated Ethernet wiring. Refer to EtherCAT in

Section 2: Communications in the ACSELERATOR RTAC

SEL-5033 Instruction Manual to learn more about con-

figuring a network.

If an Axion node contains two SEL-2243 modules, then

the EtherCAT ports in both power couplers will operate

normally even if one power supply becomes unavailable.

The remaining power supply will serve as the source for

all I/O modules and communications needs.

Mechanical Installation

Each SEL-2242 chassis/backplane has ten slots, labeled

Athrough J. Only slots A, B, and Csupport the SEL-2243

Power Coupler module.

To install the power coupler, tip the top of the module

away from the chassis, align the notch on the bottom of

the module with the slot you have selected in the chassis,

and place the module on the bottom lip of the chassis

(Figure 2). The module is aligned properly when it rests

entirely on the lip of the chassis.

Figure 2 Proper Module Placement

Next, carefully rotate the module into the chassis, mak-

ing sure that the alignment pin fits into the corresponding

slot at the top of the chassis (refer to Figure 3). Finally,

press the module firmly into the chassis and tighten the

chassis retaining screw.

Connections

General

Terminals are not intended for use with bare conductors.

Solid or stranded wire can be used with ferrule or spade

terminals. The customer is responsible for verifying that

wire insulation and temperature ratings are sufficient for

their application.

Power

DANGER

Contact with this circuitry may cause electrical shock that can result in

injury or death.

CAUTION

Capacitors should be safely discharged during decommissioning.

The power terminals on the high-voltage power coupler

(1 (+/H) and 2 (–/N)) must connect to 120/240 Vac with

the proper polarity or to 125/250 Vdc. The power

terminals on the low-voltage power coupler (1 (+/H) and 2

(–/N)) must connect to 24/48 Vdc. The power terminals

are isolated from the chassis ground. Use 14 AWG

(2.1 mm2) with an external 15 A branch circuit

protection device or 12 AWG (3.3 mm2) wire with an

external 20 A branch circuit protection device.

Grounding (Earthing)

Connect the ground terminal labeled GND (3) on the

power coupler to a rack frame or switchgear ground for

proper safety and performance. Use 14 AWG (2.5 mm2)

wire of sufficient current capacity and insulation voltage

ratings that is less than 2 m (6.6 ft) in length for the

ground connection.

EtherCAT Ports

CAUTION

Always ensure that power couplers are not connected to any Ethernet

switches or other Ethernet devices, including RJ45-to-fiber-optic

converters. The power coupler EtherCAT ports are only for direct

connections between power couplers of the same type or to an RTAC

EtherCAT port. Connecting a power coupler to any other Ethernet device

can cause the EtherCAT network to stop communicating completely or

have unpredictable behavior.

The SEL-2243 includes two 10/100BASE-T or

100BASE-FX Ethernet ports dedicated for EtherCAT

protocol. Use a standard RJ45 connector for a copper

port and an LC connector for a fiber-optic port to connect

PORT 1 or PORT 2 of the module. Make each connection by

using a direct cable to the next device. Use SEL cable

SEL-C627 with copper ports. Copper cables for EtherCAT

connections should be less than 3 m (10 ft) in length.

Buttons and LEDs

Each power coupler includes a LAMP TEST button useful

for system testing. When depressed, all module LEDs on

the terminal side and front panel (rack mount only) will

illuminate.

The green LED labeled POWER on the SEL-2243 will illu-

minate if incoming power is present and the power sup-

ply is operating normally. The LEDs labeled ENABLED

and ALARM are related to EtherCAT network operation.

The green ENABLED LED will illuminate when the mod-

ule is operating normally on the network. The ALARM

LED will illuminate during network initialization or

when there is a problem with the network.
