ApplicationPrima, is a compact, voltage-operated,attracted armature auxiliary relay withinstantaneous and time delayed auxiliaryfunctions. It has been designed to fulfil theneed for contact multiplication inprotection and control environments, froma brief developed as a result of worldwidemarket studies. Great emphasis has beenplaced on making it as easy as possible tospecify, order, configure and install.

Description

Ease of installation is ensured by thetwo-part design in which the relay plugsinto a socket which may be specifiedwith front or rear connected terminals. Asnaplock feature between relay andsocket, eliminates the need for separatewire clips. The front-connected socket,mainly for DIN rail mounting, mayalternatively be mounted on a solidpanel via a single fixing screw, whilst therear- connected design clips or screwfixes to suitable panel cut-outs or may beaccommodated on a special rackmounting frame.

The two types of terminal availableinclude a unique captive nut designwhich makes for wiring time reductionsof up to 75%.

The relays are available as either self-reset, electrical reset or hand/electricalreset types. The range includes amechanical operation indicator asstandard and an optional integratedtimer to minimise panel spacerequirements.

All the contacts are changeover type,designed to the latest IEC 255 standards,ensuring maximum flexibility withsimplified ordering.

Relay

Contacts

Self reset (PRS) models have 4changeover contacts except those withdelayed drop-off timer which have only3 contacts. Hand/electrical reset models(PRH) and electrical reset models (PRE)have 3 changeover contacts. All havesilver contact tips to provide long lifeand reliability over a wide range ofduties.

Optional magnetic blow-out contacts arerecommended for heavy or highlyinductive loads.

See Technical Data for contact ratings.

Operation indicators

All relays are fitted with an operationindicator that follows the contactoperation, with the exception of self-resetting instantaneous relays type PRSwhich, when required, can be fitted witha hand reset indicator.

Test/reset buttons

Relays other than the electrical resetmodel are available with an optional testbutton to check contact and followingindicator operation.

A reset button is fitted on all modelsexcept the electrical reset and self resetrelays with a following flag.

Both test and reset buttons are flush withthe cover and cannot be accidentallyoperated.

Time delays

The dc self-reset relays can be fitted withadjustable timers for delayed operationor delayed reset. These have a widerange, from 0.1 to 270s, to be set by thecustomer in 4 ranges with overlappingadjustment. By installing rectifier typePA01 in series with a dc relay, timedelayed relays can be used on acsupplies. Timers are supplied set to theirminimum values.

The controls are behind a hinged cover.Adjustment is by screwdriver, see Figure2. The rotary switch, on the right handside, allows the customer to select from 4timing ranges. The trimpot is then usedfor adjustment within the time rangeselected, (see Technical Data).

The cover has provision for the customerto affix an identification label.

Socket

Relay connector

Connection between the relay bladesand the socket input and outputterminals is by means of pre-formedphosphor bronze strips.

Terminal options:• M3 screw suitable for crimped pre-

insulated ring tongue connectors

• Cage clamp, suitable for crimpedpre-insulated connectors (flat bladeor boot-lace ferrule) or wires withstripped ends are considered to bethe least preferred due to wiresettlement with time. Where two wiresare used in the same terminal theymust be of the same size.

Both M3 and cage clamp terminals willaccept two standard crimped wiredconnectors per way. Terminals will accept wire sizes of 0.5 - 2.5mm2.

Mounting

Prima relays are generally suitable formounting side by side, with no gapbetween adjacent sockets. This allowsmultiple schemes to be installed in theminimum of panel space. However,PRIMA relays which are permanentlyenergised at elevated ambienttemperature (greater than 40°C) shouldhave a vacant space, equivalent to thewidth of one PRIMA, between adjacentrelays. Panels designed should alwaysconsider thermal gradients, and wherePRIMA relays are installed near the topof non-ventilated panels, at least 100mmair gap must be allowed between the topof the relays and the underside of panelroof.

Front-connected

This is designed primarily for DIN railmounting. The wire clip area of thesocket must first be hooked onto the DINrail. Pressure should then be applied tothe top of the socket until the bottom ofthe socket clips into place. To remove thesocket, pressure should be applied to thetop of the socket; the bottom of thesocket can then be pulled away from theDIN rail and lifted off. It can also bepanel mounted using a single No 6 self-tapping screw. Two location pegs aremoulded into the housing to preventrotation. See Figure 11.

Rear-connected

This is designed to be rack mounted using the clip-on mounting featureas follows: The wire clip area of the socket must be placed on the rackfirst, and pressure should then be applied to the top of the socket untilit clips into place. To remove the socket, apply pressure to the top of thesocket and push away from the rack. Alternatively, it may be panelmounted using two No 6 self-tapping screws or the clip-on mountingfeature as described above. The socket can then be lifted from the rack. See Figure 10 for details of the required cut-outs.

A custom designed 483mm (19 inch) rack is available into which 12relays will fit. See Figure 9 for rack assembly and blanking platedetails.

Relay to socket coding

A simple mechanical relay to socket coding system offering twelvecombinations is employed to prevent the relay being plugged into thewrong socket.

See Figure 3.

Contact wetting

In SCADA or alarm applications, the minimum recommended "wetting"values to ensure reliable making of contacts are 24V and 0.5VA.Where PRiMA relays are installed such that breaking of contacts willinitiate the alarm, it is recommended that the SCADA has an alarminitiation delay of at least 2ms.

This prevents spurious alarming when cubicle doors are closed, andcontinuity may be broken for a fleeting instant due to the transmittedmechanical shock.

In the most onerous application of relays being mounted directly onswing-frame cubicle doors, it is strongly recommended that any "breakto alarm" circuits utilise 1VA load for better contact wetting.

Rectifier Units

A PA01 rectifier unit may be used with relays with timer or the

24/27V rated relays to allow their use on ac supplies. The PA01 ishoused in a standard Prima case and must be used in conjunction witha socket suitable for the application.
