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.
