General information

Dalton is a locking unit that is intended for use in preventing unnecessary production stoppages,

i.e. it is not a safety lock. It can be used either as a stand-alone lock or integrated with Eden

(as a safety sensor). In the unlocked state the door is held closed by a ball catch and locked

mechanically. If necessary, the holding force of the ball catch can be adjusted. The unit only

permits locking if the ball catch is secured and when Eva is in contact with Adam (depending on

variant). When the lock input is set, the ball catch is locked.

Dalton is easily connected with an M12 connector. A Tina junction block may also be used for

distribution of the safety as well as locking functions. The Dalton status is indicated by LEDs and

can also be read by PLC via the information output.

Installation precautions

The Dalton lock shall be installed by trained personnel following the Safety regulations, standards

and the Machine directive. All safety functions shall be tested before the starting up of the

machine.

Maintenance

Before performing maintenance - Do not open the Dalton prior the warranty has elapsed. Opened

units will not be given warranty if claims are made.

The ball-catch is lubricated from factory. More lubrication can be added when needed. Dismount

the end caps and adjustment screws. Remove the springs, pistons and balls. Add grease on the

ball seat, springs, pistons and balls.

Remount the details.

Warning! The piston o-rings may not be damaged. This will have an negative effect on the IP-

rating.

Caution!

This product shall be handled with caution. The product should be replaced with the same type of

product if there is a situation where it has been dropped on the oor, knocked strongly, exposed

to extreme voltages, temperatures or humidity beyond the specied limits. Dalton may never be

used as a door stop.

In case of functional problems

The entire system should be tested without disconnecting the power supply. Check the LED

indicators according to ”Indication and information” under the chapter ”Technical data“ in this

manual. If the problem is not solved, please contact the nearest ABB/Jokab Safety Service Ofce

or reseller.

Force to open

Do not attempt to force the lock open while Dalton is locked, as it will cause permanent damage

to the device.

Mechanical design

Detection of tongue

The tongue has to be mounted correctly to ensure optimized detection towards Dalton. The

smallest of the two screws on the back side of the mounting bracket for the tongue must always

be heading towards Dalton or downwards (see pictures below).

Adjustment of tongue

When the door is closed the balls of the ball-catch must not be pressed by the tongue. The lock

has to be mounted so that the tongue is well centered in the ball-catch in the X-direction and

within the measurements stated for the Y- and Z-directions. When the balls are under pressure,

the lock will not work reliably and the dust and liquid protection is reduced.

Vertical installation

- or horizontal on hatch opened upward or downward

The gure shows the optimized way to mount Dalton in situations with a narrow radius.

Distance from hinge to tongue

If the axis of the hinge (A) is in line with the centre of the ball-catch the tongue can be mounted at

a short distance (X) between the hinge and tongue. If instead the axis of the hinge (B) is outside

the centre of the ball-catch (with the distance Y) the distance (X) between hinge and tongue also

must be increased.

Horizontal installation

- or vertical on a hatch opened upward or downward

If the only possibillity is to mount the Dalton horizontally, the following aspects has to be

considered:

If the door hinge is not in line with the centre of the balls a side movement between ball-catch and

tongue will be introduced when the door is closing (see picture below).

Caution! The tongue may never under any circumstances touch anything else than the balls in

the ball-catch when the door is closing, otherwise the lock will be damaged.

Allmän information

Dalton är en låsenhet avsedd för att förhindra onödiga produktionsstopp, och är d.v.s. inte ett

säkerhetslås. Det kan användas antingen som ett fristående lås, eller integrerat med Eden

(som en säker förreglingsbrytare). I olåst läge hålls dörren stängd med ett kulsnäppe, och låses

mekaniskt. Kulsnäppets hållkraft kan justeras vid behov. Enheten tillåter endast låsning när

kulsnäppet är säkrat och Eva är i kontakt med Adam (om möjligt, beror på modell). Kulsnäppet

låser när låssignal sätts hög.

Dalton ansluts enkelt med en M12-kontakt. Ett Tina-förgreningsblock kan också användas för att

sprida både säkerhet- och låsfunktionerna. Lysdioder på enheten indikerar Daltons status, vilken

även kan läsas av PLC genom enhetens informationsutgång.

Installationsföreskrifter

Dalton ska installeras av behörig elektriker i enlighet med säkerhetsföreskrifter, angivna

standarder och Maskindirektivet. Alla säkerhetsfunktioner måste testas innan systemet startas.

Underhåll

Innan något underhåll utförs - Öppna inte Dalton innan garantiperioden har löpt ut. Garantin

gäller aldrig efter att enheten öppnats.

Smörjmedel är applicerat på kulsnäppet från fabrik. Ytterligare smörjmedel kan tillföras vid behov.

Lossa ändlock och justeringsskruvar. Ta bort fjäder, kolv och kulor. Applicera smörjmedel på

kulfäste, fjäder, kolvar och kulor.

Sätt tillbaka samtliga detaljer.

Varning! Kolvens o-ringar får inte skadas. Detta skulle försämra enhetens IP-klass.

Aktas!

Denna produkt skall hanteras varsamt. Produkten ska bytas ut mot en likadan enhet om det

uppstår en situation där den tappas i golvet eller utstår en kraftig stöt, utsätts för extrema

spänningar, temperaturer eller luftfuktigheter bortom de specicerade gränsvärdena.

Dalton får aldrig användas som ett dörrstopp.

Vid funktionsproblem

Hela systemet testas utan att bryta strömförsörjningen. Kolla lysdiodernas indikering enligt

„Indikering och information“ under kapitlet „Tekniska data“ i denna manual. Om problemet

kvarstår, var vänlig kontakta närmaste ABB/Jokab Safety servicekontor eller återförsäljare.

Forcering av låset

Försök aldrig att forcera upp Dalton när enheten är låst, då det kommer att skada enheten

permanent.
