Electronics miniaturization and dispersal of the systems into sub-assemblies require a total

consideration of the problems of dimensions and wiring.

Our range of alarm sequences in actibloc plug-in units has been designed in order to solve

these problems and to supply a complete service in this matter.

This modular technology employs a system of blocks composing the active parts plugged

into sockets, providing 6 screw connections and 8 common connections by snap-on buses.

Thermal characteristics

Example of use of the nomograph:- mounting A,- sequence 2SAD1 125 V,- power consumption of the Actibloc: 2 W (consumption of the electronics + fault contacts).

The maximum temperature (51 C here) isdetermined by intersection of the straight lineof the ambient temperatures

with that joining point A with point 2W of the verticalpower line.

N.B.: The nomograph above can be used whateverthe number of blocks with a maximum of 55 blocksper terminal. For quantities of less than 9 formounting A, 11 for mounting B, 21 for mounting C,the maximum ambient temperature can be higher:please consult us.

Thermic resistance Rth ofan Actibloc unit in °C/W.

MountingNumberof blocks

In order to ensure good working conditions, thechoice of mounting should be made with regardto the power consumption of the Actibloc and tothe ambient temperature.

Inversely, knowing the type of mounting A, B or Cand the power dissipated, the nomograph belowallows determination of the maximum admissibleambient temperature.

no busbarconnectionto faultcontacts

A wiring standard has been defined :- between plug-in blocks (internal interconnections),- between blocks and exterior (externalinterconnections).This standard wiring for any type of sequence usedis described below.

External connection

ON 1SACDV CONNECTING BLOCKThe 0 volt supply wire is connected to the terminal A(1) of the socket ; the positive Vdc is connected toterminal C (3) of the socket.

These 2 polarities are distributed on 2 busbars(busbar 6 for 0 volt, busbar 4 for positive Vdc) byintermediary of bridgings 1-6 and 3-4 on theconnecting block.

The wire from the lamp test pushbutton is connectedto terminal D (12) of the socket.

The bridging 12-5 effects interconnection betweenD (12) and busbar 5.

The wire from the acknowledge pushbutton or themanual reset pushbutton (according to type ofsequence) is connected to terminal F (14) of thesocket.

The bridging 10-14 effects interconnection betweenF (14) and busbar 10. Thus:

ON 1SADCOM COMMON BLOCKConnection of klaxon at A (1) and B (2).

The wire from the klaxon off pushbutton isconnected to terminal F (14).

ON SEQUENCE BLOCKTerminals A (1), B (2) are reserved for fault inputs.

Terminals E (13) and F (14) are reserved for outputsto signal lights.

Internal connection

By 8 busbars which establish interconnectionbetween blocks.

The standard assignment of busbars is shownopposite.

Note 1 : The Actibloc socket provides for the pas-sage of 14 busbars maximum. In this particular case,no screwed terminals will be available on thesockets. In the standard version (3V-3V socketsP/N 6621 532-13) the socket is equipped with 8busbars maximum. In this case, 6 screwed terminalsare available for external connections .

Note 2 : Possibility of interlocking acknowledgementby klaxon off, by wiring. That is to say, the operatorcannot acknowledge before stopping the klaxon.This allows recognition of transient faults. Thisinterlocking is systematically represented in thewiring diagrams on the following pages.

Access to busbar is possible as bridgingis on front face of connecting block.

Precautions

- PRECAUTIONS TO BE TAKENFOR POWER SUPPLY

Direct rectified, filtered or regulated voltage.3 ranges of standard voltages: 24 - 48 - 125 V (rated value).Permissible tolerance: +15% -20%.Permissible ripple: 10% peak to peak of the rated value of the voltage(percentage within the working range).

- 18 V eff for a Vdc = 24 V- 36 V eff for a Vdc = 48 V- 78 V eff for a Vdc = 110 V- 90 V eff for a Vdc = 125 V

N.B. : if the power supply is made by user, thelimits defined opposite must be respected.The transformer must not exceed, on thesecondary :

The power supply should not be common toalarm sequences and to interfering circuits(electromagnetic elements, solenoïd valves,relays...), generators of transient over-voltages.When a single power supply source is used, asystem of protection must be placed on thesecircuits (for example: protection diode) in order toavoid these over-voltages.

- Never open the 0 volt circuit.

- distribution from one power supply to severalsystems must be carried out by star connectionfrom the source.

The acquisition of data is generally effected bythe opening or closing of a loop by the distantsensor. As this is usually a common polarity, theoperator is tempted to use 1 common lead forconducting the polarity. This is possible if theloop constituted by the polarity wire and thesensor returns, be as small as possible (to avoidpossible coupling with the interfering circuits). Forthis, it is recommended to have the "out" wire andthe "return" wire(s) in the same cable.In all cases, separate the wires carrying the alarmsequence signals from the wires carrying thepower signals.

Regrouping with follow-up

GENERALThe regrouping with follow-up sequenceallows to group and to transfert on a singlesequence situated in a central post, theaudible and optical alarms of severalsequences situated in a local post andcorresponding to a "family" of faults (faultsof electrical - mechanical - chemical - thermic,etc.origin).

� Regrouping does not change the basic sequentialof the local sequence.Consequently, all ISA standards described on thepreceding pages apply to sequences withregrouping.

DESCRIPTION OF FUNCTIONINGThe follow-up means that all new faultsappearing in a group re-activate the remotesequence after acknowledgement of this, andin spite of the presence of previous faults inthe group.

Example using an ISA1 sequence.� Appearance of fault n:

- local and remote audible and optical signals:L and Ln lamps on flashing,

- klaxon off, local and remote acknowledge.Passage to steady light of the local Ln lamp and of theL lamp of the remote sequence

2SAD1R PARTICULARITIES

� 3 voltage level output at D(12):consequently, no individual acknowledge possible.Common acknowledge by busbar 10 only.- his regrouping output is common to 2 fault inputs.- The D (12) outputs of local sequences of a same

group are linked together and connected at inputF (14) and E (13) of the 3-level regrouping block.

� The LED diode on the front is the image of the alarmsignal and not of the fault contact status.

� Consumption:on normal or on alert including consumption of thecontrol contacts.24 V __________________________ 1.0 W48 V __________________________ 1.5 W

1SAD2R PARTICULARITIES

� 3 voltage level output at E (13).

� No recopy fault memorized.

� Each local sequence preserves its independenceand gives optical and audible indications withacknowledge, klaxon off, eventual reset, lamp testetc., locally.

� The local sequence is a 2SAD1R or 1SAD2Rsequence has a regrouping output with 3 voltagelevels.

� A regrouping channel or bundle is realized byparalleling these 3-level outputs.

� A 3-level regrouping block is required to control theregrouped sequence at the central post.

� The regrouped sequence is a 2SAD1 or 1SAD2sequence having its own controls for acknowledge,klaxon off, reset, lamp test etc. However, certaincontrols may be common(klaxon off, lamp test).

� Appearance of a fault n+1 in the group:- local audible and optical signals:

Ln+1 lamp flashes,- follow-up of the remote sequence: L flashes

� Clearance of all faults:- extinction of all local lamps and the remote

L lamp.

N.B.: Regrouping takes place up to fault clearance, i.e.the remote lamp does not go out until all faults havedisappeared locally.

2R3ND REGROUPING BLOCK PARTICULARITIES

This block possesses 2 independent channels.It allows transmission of an all or nothinginformation in the form of dry contact for attackingthe regrouped sequence with follow-up onappearance of a new fault.

� 1st bundle input F (14) ➔ output contactB (2) - C (3)2nd bundle input E (13) ➔ output contactA (1) - D (12)

� Status NO-NC of contacts at output: selectionof type of contact by jumper accessible fromthe front of the block.

� Consumption:24 V __________________________ 1.4 W48 V __________________________ 1.4 W

� Characteristics of contacts:- Max. voltage: 150 Vdc, 125 Vac- Max. current: 2A- Max. break capacity: 30 W/60 VA

3 types of plug-in block are required for constituting analarm sequence terminal.

THE 1SACDV CONNECTING BLOCK

- P/N 6674 550.16

This block allows access to the internal busbars forcross-connection between blocks. The extremity ofeach row of sequences must have a connectingblock.

THE KLAXON-FLASHER COMMON BLOCK

1SADCOM 24 V - P/N 6674 539.071SADCOM 48 V - P/N 6674 540.141SADCOM 125 V - P/N 6674 541.01

This block integrates the 2 functions: klaxon memoryand flasher.

The klaxon memory delivers a potential-free SPDTcontact for control of the klaxon.

Breaking capacity:

100 W on 30 Vdc80 W on 50 Vdc30 W on 125 Vdc50 VA on 220 Vac.

The flasher allows processing of 100 faultsmaximum, i.e. 100 1SAD2 single sequences, or 502SAD1 double sequences.

For more than this, provide 1 supplementary blockfor each 100 faults.

THE SEQUENCE BLOCK

Use the correspondance table (page EN J3-1-10) todetermine the part number of the type ofstandardized sequence selected on page EN J3-0.

This block integrates 1 sequence (1SAD2) or 2sequences (2SAD1) and carries out the sequentialprocessing of data given by the fault contact.

Essential mounting accessories

- Provide 1 3 V-3 V socket P/N 6621 532.13 for each plug-inblock.

- Provide 1 DIN mounting foot P/N 6620 079.13 for mountingthe socket on DIN 1 rail.

- Busbar of 1 m (40") P/N 6621 527.16For lengths of less than 1 m (40") the busbar must be cutto the appropriate size by the user.

- Provide 2 BAD1D30 end stops P/N 6673 556.07 at theextremity of each terminal.

Example of an order

For the processing of 15 fault contacts in compliance with theISA 1 standard: imposed voltage supply: 48 V.

We shall take 8 2SAD1 48 V sequences1 common block 1SADCOM 48 V1 connecting block 1SACDV➨Total 10 Actibloc, i.e.length of terminal = 18 mm x 10= 180 mm (.71" x 10 = 7.1").

6 busbars will be required for the ISA 1.i.e. total length of busbar:6 x 180 = 1080 mm > 1 m ; consequently, use 2 busbars(6 x 7.1" = 42.5" > 40") .
