How to dismantle system 2200
Picture 1:
The back panel of the device is detached from the housing by way of a screwdriver.
Picture 2:
After this, the back panel can be pulled out together with the PCB, but please notice the position of the PCB as there is a
number of different positions in the house. Do not pull the wires unnecessarily, instead pull the PCB. Switches and jumpers
can now be moved.
When assembling the back plate and housing, please make sure no wires are stuck.

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 proportional 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).
• The output current is enabled / disabled by a digital controlling signal. Please note that the output current is disconnected
until +Vsupply is applied to terminal 3.
• 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.
• 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.
Mounting
• Mounting for a standard 11-pole socket which can be adapted for DIN rail or plate use with PR’s 7023 adaptor and 7024

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 signal. 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 kΩ
load 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.

Documentation for routing diagram
General
The configuration 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 2 as outlined
in the routing diagram.
Programming
Activating 2 in 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

4.3 DO - Setting of ramp time down
The ramp time is set in seconds.
Valid selections are 0...10 s.
5.0 PAR - Setting of parameters for output
5.1 REV - Selection of direct / inverted output
0 = direct, 1 = inverted.
Valid selections are 0 or 1.
5.2 DOD - Setting of deadband for e.g. joystick
The parameter is entered as a percentage of the input span.
Valid selections are 0...99.9%.
5.3 FRQ - Setting of modulation frequency for output current
The frequency is set in Hz.
Valid selections are 8...400 Hz.
5.4 GA - Setting of Ivalve
The parameter is set in Ampere - with two decimals.
Valid selections are 0...3.00 A
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.
