Electronic Actuator for 34 Series Pilot Controls
Thank you for purchasing a 34 Series Electronic Actuated
Pilto Control. With proper maintenance, the actuator will perform
indefinitely and provide very accurate and reliable valve control. It
is built with the latest technology utilizing the highest quality com-
ponents.
34 Series Controls
The 34 Series Actuated Pilot Controls for 300 Series Valves
consist of a hydraulic pilot subassembly and 130VC-3 Actuator.
The Cla-Val Model CD S-34, CRA-34, CRD-34, CMC-34, and
CRL-34 pilot controls are factory set to full adjustment range of the
pilot subassembly. The 34 Series Actuator accepts a 4 - 20 mA
remote command set point or dry contact closure and positions
spring-loaded hydraulic pilot subassembly as it maintains set point
of pressure or flow rate. The pilot subassembly is automatically lin-
ear between the limit settings.
34 Series Control Operation
A.) The 34 Series actuator allows 34 Series Controls to be
used in valve remote control applications where a simple change
of pilot set-point is needed. SCADA instrumentation provides set-
point control and verification communication based on this scale.
The actuator can also be controlled by simple contact closure.
B.) Other suitable valve remote control applications are
where 4 - 20 mA command input signal is calibrated to specific
high and low range values. SCADA instrumentation provides set-
point control and verification communication based on system
dynamic conditions and valve’s re-ranged scale. Using a laptop
computer, the 34 Series actuator is calibrated in the field to specific
minimum and maximum pressure or flow control settings that are
in direct proportion to 4 - 20 mA command signal. Once values are
established, the valve will be linear between limits and set-point
will not exceed limits throughout the 4 - 20 mA signal range. For
example, when actuator is calibrated to 4 mA = 50 psi to 20 mA =
100 psi, a 12 mA command signal will result in a 75 psi set point.
34 Series Actuator Hardware Set-up
BEFORE running actuator or software program, complete the
following hookup steps:
Use good field wiring practices for low voltage DC analog instrumen-
tation wiring (use 20-gauge twisted pair shielded wire minimum).
Avoid potential ground loops. Avoid over tightening wiring connector
fasteners.
The enclosure is rated IP-68 (similar to NEMA 6P) submersible for
short periods of time. It is not intended for continuous underwater
use. Consult Cla-Val factory technical support if you have questions.
The ten-wire ten meter cable is permanently attached to 34 Series
actuator and should be terminated in suitable junction box or
directly into an above grade RTU or similar device. Care should be
used when attaching to wires to avoid damage. Installation of suit-
able protection from lightning is highly recommended.
There are no user serviceable parts inside the actuator and tam-
pering or opening it will void the warranty. The ten-wire actuator
cable is permanently attached. Internal damage not covered by
warranty will occur if cable is removed.
FIELD WIRING STEPS:
Terminate wires only applicable to your application. For example,
minimal wiring requirements for power and remote set point are:
1.) Attach 12 to 24 VDC power to 34 Series Actuator cable.
Black wire is for (-) negative; Red wire is for (+) positive. Provide
minimum 500 mA supply.
2.) Attach 4 to 20 mA analog Remote Command Input (from
SCADA system or loop calibrator) to 34 Series Actuator cable.
Yellow is positive and Grey is negative.
Download Wiring Diagram from website (www.cla-val.com)
3.) After wiring is complete and actuator is powered, it can be
used with 4 - 20 mA remote command input signal scaled to factory
default pilot control adjustment range (Operation A, above).
Troubleshooting Actuator Set-up
1.) The actuator LED will remain red for approximately 30
seconds after power on, and then will switch to green indicating
actuator is OK and that internal start-up test is complete.
2.) The actuator LED blinks red if there is a problem. After
resolving the problem, reset the actuator by turning power off for
ten seconds then on again.
3.) The actuator blinks red and green if still in the calibration
mode. It will be necessary to finish calibration.

34 Series Software
For Operation A (above) applications, no changes to the 34
Series control preset values are needed. For Operation B (above)
applications, the 34 Series Software kit is used to ONLY change
factory-set values of: 1) range limits (high and low), 2) rotational
speed of actuator, and 3) loss of signal mode. It is used only for
set-up of 34 Series pilot controls during initial valve start-up or
during valve repair.
Cla-Val 34 Series Software is required to communicate between
your Windows laptop computer and the 34 Series Actuator.
Required is the free software program, a special multi-USB con-
nector cable, and these instructions. The software is obtained by
downloading from our website. Only one cable is needed to work
with all 34 Series Actuators. Replacement cables (p/n
20519203A) can be ordered at extra cost. Do not use this soft-
ware for remote control of 34 Series Actuator.

34 Series Actuator and Software Set-up
Change 34 Series Actuator configuration from factory default set-
tings, by using free download software from website (www.cla-
val.com). To set up a communication link with 34 Series Actuator,
first install software and cable driver and then special USB commu-
nications cable in laptop computer. After installing driver and com-
munication cable, the actuator must be powered for link to work.
Follow hardware set-up and wiring diagram instructions. Your com-
puter must be on before powering the actuator.
ardware set-up steps must be completed before program will
communicate and change 34 Series factory default settings. Until
wiring and power connections are made to the actuator, the soft-
ware program can be opened, but new parameters can not be cre-
ated or stored or sent to actuator. Changes to parameters must be
done "live" and while control valve is operating.
Cla-Val multi- SB Driver Setup
When 34 Series communications cable is installed in your laptop
computer USB port for the first time, Windows will search your
computer for the cable multi-USB driver. If Windows Plug-and-
Play does not automatically find the driver and connect to actuator,
then the cable driver must be set-up manually. Please refer to doc-
ument “N-USB Cable Driver Install” instructions to manually acti-
vate the cable driver.

Calibration - Static and Dynamic
Before beginning the calibration process, determine if it is actual-
ly necessary! The actuator, if new, has been factory calibrated to
the spring range shown on the pilot and may not require further
calibration (30-300 spring range is calibrated from 40 to 140 psi).
Static calibration
Static calibration is a fast and convenient method of calibrating
the actuator by calculating the 4 and 20 mA values rather than
raise or lower the actual system pressure. Dynamic Calibration
requires that the system pressure is actually raised and lowered
to the system values desired.
The “Set Range” window will launch either Static or Dynamic cali-
bration. When the "Set Range" is activated, the following mes-
sage will be displayed. To continue with calibration, click "OK”, if
not click "Cancel".
1 Select "Static Calibration" Mode. The "CPC Motor"
check box should unchecked (Disabled).
2 Use increase and decrease buttons to put valve in control
of system. This will establish the reference set point.
3 Determine the pilot spring range. (Check nameplate label
on pilot). Get the pressure change per turn per pilot revolu
tion from the spring chart. Calculate the number of turns
between the reference set point and desired low and high
pressures.
4 These numbers are the "Value at 4 mA" and the Value at
20 mA". Numbers must be positive and can have up to 2
decimal places.
5 Enter the low value in set-point window (1).
6 Enter the high value in set-point window (2).
7 Click "Write Set Range" tab to complete actuator to
complete calibration.

Example:
Valve is in control operating at 45 psi (3 bar).
The desired pressure at 4 mA is 30 psi (2 bar).
The desired pressure at 20 mA is 70 psi (4.8 bar).
From the spring chart, using a 15-75 spring, the pressure per turn is 10.2 psi (0.7 bar). The number of turns to Low set
point is equal to 45 psi (3 bar) minus 30 psi (2 bar) divided by 10.2 psi (0.7 bar) = 1.47 turns. The number of turns to
igh set point is equal to 70 psi (4.82 bar) minus 45 psi (3 bar) divided by 10.2 psi (0.6 bar) = 2.45 turns.

9 When all values have been entered, click on "Write Set Range". Dynamic calibration is done.
Configuration
Use the configuration mode to set the rotation speed, dead band and loss of signal values.
1 Rotation speed affects the response time of the valve between set-points. The default condition is 1 second on-time, 5
seconds off-time achieving at rotation speed of 1.2 rpm. Entering a ‘0’ (zero) on time and ‘0’ (zero) off time will achieve a
continuous rotation speed of 6 rpm (maximum speed).
Make sure that the values entered are appropriate to your system to minimize the potential for surge.
2 Dead band - The default value is 0.1 mA. This value can be increased depending on the stability of the of the set point
signal. The actuator is internally isolated however, If the set point is inherently unstable, the actuator can dither. If this
happens, improve the signal or increase the dead band.
3 Choose the loss of set point signal mode:
a. Go to 4 mA: Actuator will default to the 4 mA position (low set point).
b. Last position: Actuator will maintain the last position.
c. Go to 20 mA: Actuator will default to the 20 mA position (high set point).
4 Click on "Write Configuration" button to complete configuration.

Alarms
The actuator has a Low and igh Alarm with an adjustable hysteresis and is activated as shown in the lower window:
Example: 10% Löw alarm = 4 mA + (10% x 16 mA) = 5.6 mA. 90% igh alarm = 4mA + (90% x 16 mA) = 18.4 mA.
Hysteresis
1 ysteresis prevents chattering of the alarms when the set point is very close to the alarm status. It is calculated as follows:
4 mA + (2% x 16 mA) = 0.32 mA. Low alarm hysteresis therefore equals 5.6 mA + 0.32 mA = 5.92 mA. igh alarm
hysteresis equals 18.4 mA - 0.32 mA = 18.08 mA.
2 Enter the requested percentage, for the alarms and hysteresis.

What are the default settings for the 34 Series actuator?
Factory default setting for 34 Series Actuator range parameter is
the full pilot spring range scaled to match the 4 to 20 mA Remote
Command Input analog signal. Factory default setting for 34 Series
Actuator rotation speed is one rpm with 24 VDC power.
How do I get the software to work with the actuator?
To set up a link with 34 Series Actuator, first install cable driver and
then the special multi-USB communications cable. After installing
driver and communication cable, the Actuator must be powered for
link to work. Follow wiring diagram and hardware hookup instruc-
tions. Download Wiring Diagram from website (www.cla-val.com).
How do I install Special SB Communication Cable?
When communications cable is installed in your laptop computer
USB port for the first time, Windows will search your computer for
the cable USB driver. If Windows Plug and Play does not automat-
ically find the driver and connect to actuator, then the cable driver
must be set up manually. Windows will take you step-by-step
through the manual set up process. The cable USB driver is
installed during software download. You will have to browse to the
Cla-Val folder created during download where the driver file is
located. Details are in this manual.
My computer does not have a SB port
Older laptop computers with only Serial port may have a problem
using USB to Serial adapter with special USB connector cable and
communicating with 34 Series actuator. Make sure the USB to
Serial adapter cable is less than 18 inches long. Also, USB exten-
sion cables should not be used because they will degrade signals
and cause problems. If problem persists, consult Cla-Val factory
technical support.
Why is actuator LED still blinking red/green after I
downloaded the settings?
Once the calibration mode button is activated, all steps must be
done before downloading is begun. Actuator LED will show green
when downloading is successful and complete.
Can I make a file ahead of time and download it to
34 Series later?
All hardware hookup steps must be completed before program will
communicate and change 34 Series parameters. Until wiring and
power connections are made to the actuator, this program can be
opened, but new parameters can not be created or stored or sent
to the actuator. Changes to parameters must be done "live" and
while control valve is operating. Actuator LED will show green
when downloading is successful and complete.
