1. Introduction:
All magneticallyinfluenced switching linkse.g. magneticvalvesorrelaisundergo acertainswitching
delay. Thisdelayconsist ofthe following coefficients:
1. the time, needed to establish the magneticfield,
2. the time, needed to overcome invertia,
3. the time, needed to dismantle the magneticfield when switching off.
Toaccelerate the establishment ofthe magneticfieldand therebyto shorten the switching timeofa
switching linkduring the process off switching on, DIGISPEEDgivesan overload impulseup to
100 Voltonto the switching link'scoil.Bythisover-energizing the magneticfieldinthe coil will be
increased, whichcausesaquickerovercoming ofinvertia. During the process ofswitching of
flywheeling diodscauseadelyofthe decreasing magneticfield. It isnot possibleto renouncethemfor
reasonsofprotection againstmalfunctions.Thisincreasesthe timerequired forswitching of
essentially.DIFGISPEEDacceleratesthe dismantleling ofthe magneticfieldusing aflywheel-circleof-
26VDC and causesa decreasing switching-off time.
Result: Bytime-intervalcontrolled overload-impulsesin connection with the regulationofthe flywheel-
voltage to -56VDC the DIGISOFTcausesmagneticallyinfluenced switching linksto work
with tenth the speed.
2. Attributes:
* Microprocessorcontrolled perfomance-electricityforan excact reproducible switching behaviour.
*Version with two channels
*short circuit resistant
* two aditionalinputsforparametering the overload impulse
*LED Statusdisplayforin-and outputs
*Short recoverytimesforthe overload-impulse
*high overenergizing voltage ofup to 100VDC fora quickswiching on
* high flywheel-voltage of-56VDC forquickswitching off
*galvanicalsepartion ofthe inputs
*forswitching devicesup to 2 x24 Watt appropriated (2 x1 Ampere costantcurrent)
* 24VDC ±20%Powersupplywithout aditionalexternalpower.
*30mm lankcase made ofThermoplast-synthetics.
*Case with comfortable snap-on assembling.

3. Functional mode
.
3.1. 3.1.Switching behaviourof switching links withflywheeling diods
Normallymagneticalswitching linksareswitched on simplybyconnecting themto 24VDC. In the
diagramshownhere, thisisdone at the timeof0ms.The inductivitycausesaslowestablishing ofthe
magneticfieldand thereforeaslowestablishing ofthe magneticforce. Atthe timeof17msthe
magneticforceisestablished asfarasitisableto antagonizethe spring'sforce. Nowthe switching
movemeent isinitialized. Thisisfinished at 41ms.Atthe moment of50msthe procedureof
switchingboff begins.The builtinflywheeling diod causesaflywheeling voltage of-0.7VDC sothat the
flywheeling current de-establishesthe magneticfieldslowly.At71 ms,the spring'sforceisgreaterthan
the magneticforce, so that the switching-off movement isinitiated, which finishesat 95ms.

3.2. Behaviourof switching links withDIGISPEED during switching on oroff
Being switched on DIGISPEEDgivesan overload impulseup to 100VDC to an adjusted time(here
5ms) upon the switching link'scoil.Bythisover-energizing the magneticfieldisestablished ina
quarterofthe timeand hasfourtimesthe forceforashorttime. The overcoming ofthe spring'sforce
isdone earlier(hereat 1ms) and the switching-movemenbt isfginished earlier(inthiscaseat 8ms),
sincerthe magneticforceisstronger.Fornot overloading the switching device, the over-energizing
should be finished at at least the end ofthe switching movement (here at 5ms).
The switching off isdone at the moment of50ms.without flywheeling iode the flywheelingcurrent isset
to -56VDC bythe DIGISPEED. Thisenablesde-establishing the magneticforceveryquickly.At53ms
the spring'spowerhasallreadyovercomethe magneticforcesothat the switching off movement can
be initialized. At 67msit isallreadyfinished.
Important: To use the reguzlated flywheeling-circle'seffectseveryconnected relaisorswitching link
hasto be used without flywheeling diod!! The flywheeling current isset to -56VDC
constantlyand can not be externallychanged. Afurtherincrease offlywheeling current
doesnot lead to betterresultsin most cases.

5. Commisioning
The deviceissnapped onto the "ENcarrierrail" inthe switchboard(see chapter""9. Dimensions"" on
page 14). Through the grounded assemblyboard and it'selectricalconnection to the EN carrierrail, the
disturbancesareoptimallygrounded onto the cover.All cableconnectionshaveto be realized inacold
state Connectthe DIGISPEEDat firstwith the shortestpossiblewover-aroousing-time(run relaisor
switchingdevices without flywheeling diode)and switchon the device. Increasethe overenergizing
timeinsmall steps8regarding the recoverytime)until no furtherimprovement ofswitchimng behaviour
can be detected. Thenb switchbackto the lastoverenergizing timewith adetectableimprovement of
the switching behaviour.Torun the unitwith ahigherload doesnot makeanysensesinceitonly
causesaquickerusing up. Anoptimaladjusted over-energizing timeon the contrarywill causeno
using up aboive average.
Attention: The connection to a lightbulb, an ohmicconsumer, a valveplug with built in
LED orZener-Diode at the output of the DIGISPEED isnot allowed and can
cause thge destruction of the device.
Interrupting the connection between the DIGISPEED and a switching-linkwhile
being underload can also cause the device'sdestruction. Tryto avoid absolutelya
contact-switching ora connection that could be interrupted while being underload.
If thisisnot possible, a protection-switch hasto be created at the switching-link.
Forit'svery high switchingperfomanbce, the DIGISPEEDisnot resistant againstshort
circuits.Thereforetakecareto do the complete comissioning incoldstate.
