INTRODUCTION

GENERAL INTRODUCTION

NEW ATI enclosure integrates a new4-pole changeover switch includingelectronics control to meet standardIEC 60947-6-1. Thanks to the chan-geover switch technology, it is alwayspossible to manually operate the sys-tem to guarantee the changeover paneloperation in any situation.The new enclosure design allowsswitch front panel access to: Avoid opening of the enclosure for

manual operation Allow electronic module access for

programming and monitoring

Simplify connections between themechanical switch and the electronicmodule.

With the mode switch in manual posi-tion, Padlocking, as well as handleinsertion operations are then directlyaccessible from the front panel.The electronic module, also accessiblefrom the front panel, includes: Sources monitoring Metering display (V and f as standard) Test operations and Sequences pro-

gramming using keypad.

ATI TRANSFER PANEL RANGE

The new ATI panel range will be available from 250 A to 1600 A.

1. A mechanical switch.2. A motorized block to operate the switch electrically.3. An electronic module on the top of the motorized block, driving loss of mains

and mains return sequence.4. A reset button.

NEW MOTORIZED CHANGEOVER SWITCH

The new switch included in the enclosure is made of 3 different parts:

Standard offer includes Bottom cable entry. Top cable entry is offered as anoption.

Features and benefits: The new Motorisation block is inclu-

ded in a moulded case It is possible to remove the motorized

block and the electronic modulewithout being obliged to disconnectthe power cables

Manual operation directly acts on theshaft of the mechanical switch forbetter reliability

The complete enclosure meets stan-dard IEC 60947-6-1 (ATS applications)

The enclosure is self-powered (fromMain and Gen sources). There is noneed for an external power source toallow automatic sequence after lossof power

All thresholds and timers can be setusing the display and the keypad, orvia modbus (optional)

The standard product integratesvoltage and frequency control forbetter diagnostic

Main sensing circuit is 3 phases andGen sensing circuit is single phase

Standard product includes, phase tophase + phase to neutral voltagemeasurement and displays systemfrequency (phase 1) and switch num-ber of operations.

The product including metering allowscurrent measurement as well as powermetering (kW, kVar, kVA and PF).

Option 9: Top Cable Entry. For cables to be

routed through the top rather thanbottom. Option code is TICT.

Option 6: Auxiliary contacts for switch posi-

tion information, padlocking andAuto/Manual mode information areoptionally available. Option code isTAUX.

INTRODUCTION (continued)

OPTIONS AVAILABILITY

Factory options are delivered pre-installed in the enclosures

Option 5: A switch allowing 277 Vac specific

voltage option for customers requi-ring voltage code V601 (480/277 Vac).Option code is THVM.

Option 1: A metering module allowing standard

features + current and power meter-ing facilities on a larger backlit display.This option also integrates option 6(TAUX). Option code is TMET & TAUX.

Option 7: 2IN/2OUT.1 plug in module allowing

auxiliary contacts for Main andGenerator available information is alsoavailable as an option. Option code isTIO2.

Option 8: 1 plug in communication module,

JBUS / MODBUS protocole, canoptionally be ordered allowing remotecommunication of the changeoversystem. Option code is TCOM.

Option 2: IP54 protection rating is available as

an option. A specific protection win-dow must be installed on the frontpanel of the enclosure to avoid waterinfiltration in the enclosure. Optioncode is TIP5.

Option 3: Solid neutral link is available as an

option on the switch itself, whenswitching of the neutral cable is notrequired. Option code is TLNK.

Option 4: Lightning protection is also available

as an option to avoid ATS damage incase of a strike on the power cables.This option is highly recommendedin stormy areas. Option code is TLPRand TI02 is included.

Loose options are available, for customer mounting in the enclosures

A specific menu in the metering architecture allows monitoring of theprotection. Cf variable LIP in the mo-nitoring menu.LIP variable = 1 as soon as the pro-tection operates (fuse blow or lightningprotection operation).This information is verified every5 seconds.Error led also blinks to inform of LIPoperation.It might then either be required tochange a fuse or the lightning module.

Recommendations:You should use a shielded twisted pair(LIYCY type). In a disturbed environ-ment or large network (in terms oflength) we recommend the use of2 shielded pairs (type LIYCY-CY). Inthis case, one pair is used for the+ and the , and another pair, wherethe 2 wires are short-circuited, for the0 V.A repeater (1 channel) or an arrestor(4 channels) should be used if youintend to exceed the distance(1 500 m) and / or maximum number(31) of ATI. Please contact us formore information.

NB:A 120 ohm resistance (found on theadditional module) must be fixed atboth ends of the link.

Other solutions are available (modem,optical fibre, etc.). Please contact us.

CABLE CONNECTIONS BETWEEN SWITCHAND ELECTRONIC MODULE

A voltage sensing kit is used to providesensing and power connections fromthe switch terminals to the electronicmodule terminals.The ATI enclosures are delivered asstandard for 3 phases 4 wires applica-tions, 400/230 Vac nominal voltage.In some 3 phase 4 wires, all 3 phases 3wires, or single phase 2 or 3 wiresapplications, sensing connections keepthe same, but power connections mustbe modified according to guidelinesincluded before connection diagrams.

In standard ATI (bottomentry) generator cable isred and main cable is black.In top entry ATI main cableis red and generator cableis black.

BASIC PRODUCT USE

GENERAL INTRODUCTION

The product provides sources availabil-ity monitoring, Automatic / ManualRetransfer, Manual/Automatic or Testoperation monitoring, voltage and fre-quency metering, and good operation orerror information.

The product requires at least one typeof network configuration and a networknominal voltage configuration to be inputvia the keypad by the user.Other default values can be kept or mo-dified according to hereafter program-ming guidelines.

ELECTRONIC MODULE USAGE

The electronic module is directlymounted on the motorized block.It integrates the following features:- Voltage and frequency metering- Automatic transfer controls

Following diagram introduces prod-uct front panel.Led indication is only active oncethe product is powered (power ledactivated).

GENERAL INTRODUCTIONThe product provides sources availabilitymonitoring, Automatic/Manual Retransfer,Manual / Automatic or Test operationmonitoring, voltage and frequency metering,and good operation or error information. Theproduct provides sources error information.Furthermore, the metering module allowscurrent and power metering on a large back-lited display.

The product requires at least one type ofnetwork configuration and a network nominalvoltage configuration to be input via thekeypad by the user.Other default values can be kept or modifiedaccording to hereafter programming guide-lines.

ELECTRONIC MODULE USAGE

The electronic module is directly mountedon the motorized block.

It integrates the following features:- Voltage and frequency metering- Automatic transfer controls

Following diagram introduces productfront panel.

Led indication is only active once theproduct is powered (power ledactivated).

slave (ATI) and waits for its reply the master communicates with all the

slaves (ATI) without waiting for theirreply.

The mode of communication is theRTU (Remote Terminal Unit) usinghexadecimal characters of at least 8bits.

According to the JBUS / MODBUSprotocol, transmission time must beless than 3 silences, i.e. the emissiontime of 3 characters so that the mes-sage is processed by the ATI.

To correctly use information, thefollowing functions are important:

3 : to read n words (maximum 128).6 : to write one word.8 : to diagnose exchanges between

the master and the slave viameters 1, 3, 4, 5 and 6.

16 : to write n words (maximum 128).

Slave address Function code Address Data CRC 16

NB:When selecting slave address 0, amessage is sent to all the instrumentspresent on the network (only for func-tions 6 and 16).

Comment:The maximum reply time is 250 ms.
