2. Principle of function
Fig.:Presentation ofthe principle ofa camswitch unit
For abetter understanding ofthe function ofacamswitch unit, its principle is presented here. It has 3
outputs containing the following cams:
Output 1:Cam1:Activation point60°Deactivation point85°
Cam2:Activation point95°Deactivation point145°
Cam3:Activation point325°Deactivation point355°
Output 2:Cam1:Activation point5°Deactivation point20°
Cam2:Activation point95°Deactivation point145°
Output 3:Cam1:Activation point30°Deactivation point85°
The 3as beds presented progressions ofthe output signals occur, ifthe 3camplates turn
anticlockwise past a sensor, which scans the cams on the 0° axis.
The duration ofthe activation ofamechanical camswitch unit, i.e. the range between the on and off
position, is determined bythe length ofthe cams.The length and the position ofthe camscan onlybe
limitedlyvaried, which additionallydemands arelativelyhigh mechanical and chronological
expenditure.With the CamCon, these adjustments are realisable in afraction ofasecond, besides the
numberof the camsper bed is optional.Ameasuring system,which has been connected to the device
reports the position to the CamCon.The CamConcompares this with the programmed on and off
positions fromall the outputs.Ifaposition appears in arange ofaprogrammed on /off position
(cams), all affected outputs will be switched.

2.1. Delaytime compensation
Everymechanical switching part (e.g. relays, magnetic valves) possesses adelaytime, i.e. between
the triggering signal and the actual switching of the contacts passes acertain amount of time. Because
of that, problemscan arise during procedures in which positionings are carried out in amoved system.
Ifsuch aprocess is driven with different speeds, different positionings will arise. One would have to
generate new(de)activation points for the switching signals for everyspeed in order to overcome this.
Toexplain the problemofthe delaytimecompensation, the context shall be clarified using the
example ofapackaging machine. During the process which is presented bythe drawing, adot ofglue
is to be applied onto a precicelydefined spot ofa past going paber web.
magnetic valve
gluenozzle
drop
paper
Points wheretheglue
hits thepaper at the
different speeds.
paper track
encoder
CamCon
The systemhas the following parameters:
vp-Speed ofthe paper web
vT-Falling speed ofthe drop ofglue
d-Distance between the glue nozzle and
the paper web
TMV -Delaytime ofthe magnetic valve
This happens without delaytime compensation:
As soon as the measuring systemreaches acertain position, the CamCon sends out an impulse to the
magnetic valve. This opens the glue nozzle for ashort time, out ofwhich the drop ofglue then shoots.
Between the placing ofthe impulse and the falling ofthe drop passes acertain time, which is mainly
based on the delaytimeof the magnetic valve TMV Another delayresults in the timein which the drop
needs to cover the distance d between the glue nozzle and the surface ofthe paper.
This flight time can be calculated with:
tFlight =d
vT
So adelaytimeoftFlight+TMV results altogether. During this time,, the paper web moves acertain
distance further on. One could nowdecrease the position at which the magnetic valve is activated, so
that the drop ofglue hits the samespot as during standstill. One gains adelaytimecompensation in
this way,which however can onlyfunction at one single speed ofthe paper. As soon as the speed of
the system and the paper web is e.g. doubled, the landing range ofthe drop ofglue is moved again by
the distance x, so that it would, without delaytimecompensation, move to the rear bytwice the
distance (2 ⋅x) altogether.
The automatic delaytimecompensation ofthe CamCon makes it nowpossible to operate with
processes with variable speeds. The CamCon gathers the speeds ofthe systemcontinuallyand
adjusts the cams, which define the moments ofswitching, on line in dependence ofthe speed.
According to this, the outputs ofthe switching parts are being switched on or off earlier. The direction
ofmovement is ofno importance.

A small numerial example shall serve the illustration:
Assuming that the drive roll with the measuring systemhas acircumference of360mm,so that one
millimeter at the circumference corresponds exactlyto one angle degree ofthe measuring system.
The unit has the following parameter:
vdrop=20m/s
d=20cm
TMV =20ms
Out ofthis results a flight time ofthe drop to
tFlight= d
vT=0,2m 20m/s =10ms
So the complete delaytime amounts to Tdead, altogether = TMV + tFlight = 20ms + 10ms = 30ms
During this timethe paper web travels bythe distance x=vpaper ⋅Tdead,altogether =1m/s ⋅30ms=
30mm further on.
The switching point ofthe magnetic valve has to be transfered 30° to the front to compensate this
delaytime.
If one doubles the speed ofthe system and with that vpaper, the distance x, bywhich the paper web is
moving on, is also doubled. In this case the switching point has to be transfered by60° .
Tip: Note that in this explanation the delaytimeis asolid quantity,which is determined bythe
mechanical regulation and switching parts as well as bythe measurement ofthe construction,
hence it does not change.
Ifone were nowto programthe complete delaytimeof30mson the appropriate output ofthe
CamCon, the drop ofglue would always hit the exact spot at anyspeed.

2.1.1. Calculating the delaytime
There are several possibilities for calculating the delaytime ofa relayor a valve.
2.1.1.1. Calculating the delaytime through relocations that have alreadyoccured
Programthe switching point ofthe relayor valve during astandstill ofthe machine. Weuse the
switching point of 200 degrees in our example. Ifthe machine is nowrun with aspeed ofe.g 40 min-1,
arelocation occurs because ofthe delaytime. This relocation is measured and is 40 degrees in our
example.
Attention: Tocalculate the relocation correctlyyou have to set the programmed delaytimeofthe
camswitch unit to zero.
The delaytime ofthe switching member is calculated according to the following formula:
Delaytime ( in sec. ) = ∆way(indegrees)*60(sec./min.)
speed(inmin-1)*360(degrees/rotations)
Delaytime ( in sec. ) = 40*60
40*360 = 0.1667 sec.
The calculated delaytime is nowset in the CamCon.
2.1.1.2. Calculating the delaytime through the difference of measured values
The switching point is determined at aspeed ofe.g. 50 min-1.In our example, the programmed
switching point is at 200 degrees. The second measurement occurs at aspeed of80 min-1.The
needed switching point has to be set to 160 degrees to reach the exact switch point again at 80 min-1.
Attention: Todetermine the twoswitching points you have to set the programmed delaytimeofthe
camswitch unit to zero.
The delaytime ofthe switching member is calculated with the following formula:
Delaytime ( in sec. ) = ∆way(indegrees)*60(sec./min.)
∆speed(inmin-1)*360(degrees/rotations)
Delaytime ( in sec. ) = 40*60
30*360 = 0.222 sec.
The determined delaytimeis nowentered into the cam mechanism.Since this delaytimeis set for the
whole range ofthe speed, it nowbecomes necessaryto adjust the camto the speed at 0min-1.To
determine the exact activation point you have to enter the difference to the speed 0min-1 at the first
measured activation point. The difference is calculated according to the following formula:
∆way(in degrees) = deadtime(insec.)*∆time(inmin-1)*360(degrees/rotations)
60(sec./min.)
∆way(in degrees) = 0.222*50*360
60 = 66.6 degrees
The activation point ofthe camis nowrelocated by67 degrees, from200 degrees to 267 degrees.

4.2. The encoder
The encoder is used for getting the actual position, necessaryfor the camcontroller. Onlyencoders
with an SSI interface can be connected to CamConDC30. The SSI interface is acommon interface for
absolute single and multiturn encoders. The CamCon supplies the measuring systemwith 24Volt via
this interface. Toread the data, CamCon sends aclock signal with an RS422 level to the encoder. The
encoder the answers synchronouslywith the output (data) ofthe position in Graycode. The frequency
ofthe clocksignal depends on the length ofthe cable connecting ecoder and CamCon.The cable
length can be maximumof200 metre.
Note: The data protocol corresponds with the Stegmann SSI Norm.
Tp=clockimpulse
Tmono=mono flop time 25µs
Attention:
Use onlyacovered double entwined connection cable. The
wiring should not be near power current lines. Ground the
covers at both sides.
4.3. The outputs
CamCon is equipped with either 8or 16 short circuit-proofoutputs, depending on the version. They
emmit 24V high active signals and are not potentiallyfree. Theysupplyup to 500mApermanent
current in asurrounding temperature of25°C. Ifan output short circuits or overloads, the device
switches off with the "A-Err" message.
Attention: With inductive loads the outputs have to be switched with free wheeling
diodes.
4.4. Precautions to be taken at welding operations
For the duration ofwelding operations carried out at the machine, the connecting wires concerning the
data exchange fromthe measuring systemto the CamCon and the power supplyas well as the
grounding connections and inputs and outputs have to be separated fromthe CamCon.

6. Commissioning
Before activating the device for the first time, please checkits wiring (see chapter4. Electrical
connections).
Attention:With induced loads the outputs have to be switched with afreewheeling
diode. Covers or inductivities very close to the device inside the
switchboard have to be switched with adeletion unit as do those that are
wired to or influence the wiring of the device.
6.1. Complete deletion
After the first activation ofthe supplyvoltage the programmemoryis not in an initialized mode. This
leads to the CamCon' sdisplayshowing uncomprehendable symbols. That is whyyou (at the first
activation ofyour CamCon) have to put a complete deletion into process as follows:

The camprogramming is initiated as follows: Press the keyfor about 2sec., until the displayshows
e.g. . This indicates that no camhas been programmed on output 1in the 'Output
selection' mode. Bypressing the keyor the keyyou can nowselect the output on which you
want to programcams.
6.4.2. Shifting the activation point
Bypressing the keyyou leave the 'Output selection' mode and enter the 'Activation
point' mode . A pressing ofthe keyor the keyshifts the activation point byone step.
This is done according to the following system:
Ashort single pressing ofthe keywill erase the activation point at the previouslydisplayed preset
value, e.g. 100, and then the preset value is increased by1, e.g. to 101. Ashort pressing of the key
will lower the preset value (100 in our example) by1 and then set a newactivation point at e.g. 99.
6.4.3. Shifting the deactivation point
Pressing the keyonce more leads you fromthe 'Activation point' mode into the
'Deactivation point' mode . CamCon will first search for the deactivation point of the current
cam(e.g.: ). Bypressing the or the keythe deactivation point is shifted byone step.
This is done according to the following system:
Asingle short pressing ofthe keywill set anewswitching point at the previouslydisplayed preset
value, e.g. 100. Then the preset value is increased byone, e.g. to 101. Ashort pressing ofthe key
will lower the preset value, e.g. 100, by1and then delete the switching point 99. The newdeactivation
point is then 99. Afurther pressing ofthe keybrings you backto the 'Output selection' mode
