• Udgangsstrømmen aktiveres / afbrydes med et digitalt styresignal. Vær derfor
opmærksom på, at udgangsstrømmen er afbrudt, indtil +Vforsyning påtrykkes
terminal 3.
Indgang:
• Programmerbar strøm- eller spændingsindgang for standardsignaler i henhold
til ordreskema, joystick / potmeter eller speciel ikke-programmerbar indgang.
• Enheden har digitale indgange for eksterne styrefunktioner.
Udgang:
• Pulserende strømudgang sikrer, at den tilsluttede ventil ikke hænger.
• Modulationsfrekvensen (PWM) kan frit programmeres mellem 8 og 400 Hz.
• Det interne måle- & reguleringskredsløb sikrer, at middelstrømmen aldrig over-
stiger den indtastede Iventil.
• Hvis peak-strømmen overstiger 7 A, lukkes udgangen ned, så den ingen
strøm afgiver.

VENTILSTYRING 2224
• Programmerbar via frontknapper
• mA, V, Ωprogrammerbar indgang
• Rampetider, springværdier, invertering, chopper-
frekvens og dødbånd
• 3-cifret LED-display viser % af Iventil
• 1 eller 2 kanaler
• Moduleret strømudgang for proportionalventil
Anvendelse:
• Styring og regulering af enkelt- eller dobbeltspolede hydrauliske og pneumati-
ske proportionalventiler.
• Enheden anvendes, hvor der stilles krav om nøjagtig oliestrømsregulering, line-
ær blød acceleration og deceleration, moduleret udgangssignal og program-
merbart dødbånd.
• Er yderst velegnet til joystick-regulering af A/B bevægelse.
Teknisk karakteristik:
•Ventilstyringen 2224 er en mikroprocessor-styret enhed, som indeholder ram-
pefunktioner til blød start og stop og springfunktioner således, at dødbånd
undgås ved start og ved skift mellem A & B ventil.
• Ventilstyringens brugerinterface består af tre trykknapper og et 3-cifret LED-
display. Via dette ændres udgangsstrømme, rampetider, springværdier, chop-
per-frekvens, invertering, dødbånd og on/off rampefunktion.
• Under drift vil displayet vise aktuelt udgangssignal som % af Iventil.
• Alle parametre er password-beskyttet mod uautoriserede ændringer.
• Skift mellem A og B ventil kan ske på to måder. Ved funktion 1 vælges A ventil
ved påtrykning af +Vforsyning på terminal 2. Ved funktion 2 sker skift mellem
A / B ventil automatisk i henhold til indgangssignalets værdi (intet signal på
terminal 2).

TEKNISK BESKRIVELSE
• For at hindre at programmering kan ske under drift, er der indlagt to sik-
kerhedsforanstaltninger. Det korrekte password (030) skal indtastes i menuen
[PAS], og udgangen må ikke give signal (displayet skal vise 000). Dette opnås
ved at afbryde +Vforsyning på terminal 3.
• Enheden kan styres med joystick / potentiometer, tilsluttet den interne +10V
og evt. -10V forsyning, eller et proces strøm- / spændingssignal. Benyttes
processignal, kan indgangen kobles som differentialforstærker (DP1 switch
6 off) og dermed reducere påvirkningen fra støjfyldte signaler. Ved joystick- /
potentiometerindgang skal indgangen kobles single-ended (stellet), og der er
mulighed for at indkoble en 10kΩbelastningsmodstand (DP1 switch 5 on), så
der altid går strøm i potentiometerets glidekontakt.
•Skift mellem A / B ventil kan ske på to måder. Ved funktion 1 vælges A ventil
ved påtrykning af +Vforsyning på terminal 2. Ved funktion 2 sker skift mellem
A / B ventil automatisk i henhold til indgangssignalets værdi (intet signal på
terminal 2). Indgang: 0...50% = A ventil 100...0%. Indgang: 50...100% = B
ventil 0...100%.
• Ved tilslutning af ventilspole er det vigtigt at sikre, at impulsstrømmen =
Vfors. / Rspole ikke overskrider den tilladte spidsværdi på 7A.
• For at undgå utilsigtet betjening i forbindelse med f.eks. en upræcis neu-
tral stilling på et joystick er det muligt at programmere et dødbånd. Dette
dødbånd bevirker, at indgangen skal over et vist niveau, inden udgangen
reagerer.
• Der er mulighed for at indstille springrespons (bias), således at der tages
højde for ventilsædets vandring, inden der er oliegennemstrømning.
• Man har mulighed for at programmere to faste maksimalstrømme (Imax1
& Imax2). Skiftet mellem de to strømme sker med et eksternt PNP-signal på
terminal 7. Funktionen kan bl.a. anvendes i forbindelse med endestop, såle-
des at den sidste vandring sker langsomt.
• Ventilstyringen overholder EMC-data, når installationskablet til tilsluttede
ventiler er skærmet. Skærmen forbindes til forsyningsground.

DOKUMENTATION TIL RUTEDIAGRAM
Generelt:
Programmeringen er menustyret. Hovedmenuerne er nummereret i niveau
0 (X.0), og undermenuerne i niveau 1 (X.1...X.4). Til hver undermenu findes
en indtastningsmenu. Opbygningen er udført, så de menuer, der anvendes
oftest, ligger nærmest normaltilstanden menu 0.0.
Vær opmærksom på, at programmering kun er mulig, når der i undermenu
1.1 PAS indtastes værdien 030.
Alle foretagne ændringer gemmes først i EEPrommen, når der returneres til
normaltilstanden - menu 0.0.
Man finder rundt i underprogrammet og

6.0 PRO - Indstilling af proportionalregulator
6.1 PF - Indstilling af proportionalfaktor (Gain)
6.2 If - Indstilling af integrationsfaktor
Ved levering er PF indstillet til 0,15 og IF til 0,5. Disse indstillinger vil
fungere på langt de fleste ventiler, men kan have den ulempe at det
tager for lang tid, inden ventilen reagerer.
For optimering af reguleringsparametrene kan man med fordel anvende
følgende "tommelfingerregel" (alle øvrige parametre skal være korrekt
indstillet).
1. Forbind et DC-coupled oscilloskop direkte over spolen.
2. Indstil IF til 0,00.
3. Forøg PF, indtil kurven på oscilloskopet begynder at svinge kon-
stant.
4. Indstil PF til halvdelen af denne værdi.
5. Forøg IF, indtil kurven på oscilloskopet igen begynder at svinge
konstant.
6. Indstil IF til halvdelen af denne værdi.
Reguleringsparametrene PF og IF kan nu finjusteres med udgangs-
punkt i de fundne værdier. Mindre værdier vil gøre ventilens reaktion
langsommere men fjerne et eventuelt oversving.

• The output current is enabled / disabled by a digital controlling signal. Please
note that the output current is disconnected until +Vsupply is applied to termi-
nal 3.
Input:
• Programmable current or voltage input for standard signals acc. to order
schedule, joystick / potentiometer or a special non-programmable input.
• Digital inputs for external control functions.
Output:
• A pulsating current output prevents the connected valve from sticking.
• Optional programming of the modulation frequency (PWM) between 8 and 400 Hz.
• The internal measuring and control circuit ensures that the mean current never
exceeds the entered Ivalve.
• If the peak current exceeds 7 A the output will be disabled.
23
VALVE CONTROLLER 2224
• Front-programmable
• mA, V, and Ω-programmable input
• Ramp times, jump values, reversal, chopper frequency,
and deadband
• 3-digit LED display shows Ivalve % value
• 1 or 2 channels
• Modulated current output for proportional valve
Applications:
• Control and regulation of single or double-coil hydraulic and pneumatic pro-
portional valves.
• The unit is used for accurate oil flow regulation, linear soft acceleration and
deceleration, modulated output signal, and programmable deadband.
• Is highly suitable for joystick regulation of A/B movements.
Technical characteristics:
• The 2224 Valve Controller is a microprocessor-based unit containing ramp
functions for soft start and stop and jump functions thus avoiding deadband
at start and changes between A & B valves.
• The user interface of the valve controller consists of three pushbuttons and a
3-digit LED display. By using these, output currents, ramp times, jump values,
chopper frequency, reversal, deadband, and on/off functions are changed.
• During operation the display shows the present output signal as a % of the
Ivalve.
• All parameters are protected against unauthorised changes with a password.
• Changes between A and B valves can be made in two ways. By way of function
1, the A valve is chosen when +Vsupply is applied to terminal 2. By way of
function 2, changes between A/B valves take place automatically according
to the value of the input signal (no signal on terminal 2).

TECHNICAL DESCRIPTION
• To prevent programming during operation, two safety measures have been
included: The correct password (030) must be entered in menu [PAS], and
the output must give no signal (000 must be displayed). This is achieved by
disconnecting +Vsupply on terminal 3.
• The 2224 Valve Controller can be controlled by a joystick / potentiometer
using the internal +10 V and -10 V supply, or a process current / voltage sig-
nal. For process signals the differential amplifier (DP1 switch 6 off) will reduce
disturbances from noisy signals. Joysticks / potentiometers are connected
single-ended (grounded), and it is possible to connect a 10 kΩload resistor
(DP1 switch 5 on), providing a minimum potentiometer load current.
•A switch between A and B valves can be made in two ways. By way of
function 1, the A valve is chosen when +Vsupply is applied to terminal 2.
By way of function 2, changes between A/B valves are made automatically
according to the value of the input signal (no signal on terminal 2). Input:
0...50% = A valve 100...0%. Input: 50...100% = B valve 0...100%.
• When connecting the output to a solenoid please ensure that the peak
valve current = Vsupply / Rsolenoid does not exceed 7A.
• A deadband can be programmed to avoid unintentional activation of the
valve in connection with e.g. an inaccurate neutral position of joysticks. The
deadband introduces a threshold which must be exceeded before any output
activity will take place.
•The spring response (bias) can be adjusted to account for the valve seat
travel before oil flow.
•Two current limits can be programmed (Imax1 & Imax2) for limit stop detection
featuring slow motion before stop. The active current limit (Imax1 & Imax2) is
selected by the PNP input signal on terminal 7.
• The 2224 Valve Controller complies with EMC data only when shielded
cabling is used and the shield is connected to supply ground.

PROGRAMMING / OPERATING
THE FUNCTION KEYS
DOCUMENTATION FOR ROUTING DIAGRAM
General:
The programming is menu-controlled. The main menus are numbered in
level 0 (X.0), and the submenus are numbered in level 1 (X.1 to X.4). Each
submenu has an accompanying entry menu. The menus are structured in
such a way that the menus most frequently used are closer to the default
menu 0.0. Please note that programming is only possible when submenu
1.1 PAS has the value 030.
All changes are not permanently saved in the EEP rom, until you return to
menu 0,0.
Menus and submenus are selected by the
3 function keys 3,1, and 2as outlined
in the routing diagram.
Activating 2in the submenu will display
the current value in the entry menu.
In entry menus, the digit that can be
changed will flash.
Active digit position is shifted by the 3
key, and the value is changed by the 1
key.
In parameter selection menus you switch
between the parameters by using the 1
key.
To store changes temporarily press 31
simultaneously.
To store changes permanently go to menu 0,0.
To return to the previous menu without changing the parameters - press 2.

6.0 PRO - Setting of proportional controller
6.1 PF - Setting of proportional factor (Gain)
6.2 If - Setting of integrating factor
At delivery PF is set at 0.15 and IF at 0.5. These settings will work well
for most valves but may have the drawback that it will take too long
before the valve reacts.
In order to optimise the control parameters the following "rule-of-
thumb" can be applied (all other parameters must be set correctly).
1. Connect a DC-coupled oscilloscope direcly across the coil.
2. Set IF at 0.00.
3. Increase PF until the curve on the oscilloscope starts oscillating
constantly.
4. Set PF at half of the above value.
5. Increase IF until the curve on the oscilloscope starts oscillating
constantly.
6. Set IF at half of the above value.
The control parameters PF and IF can now be fine-tuned using the
found values. Lower values will slow the valve’s reaction time but
eliminate any overshoot.
