CPC

4-20 mA Actuated Position Control

Thank you for purchasing a CLA-VAL CPC. With appropriate care, this CPC will provide accurate and reliable control of
your valve for many years. The CPC is built with the latest technology using only very high quality components.
The CPC is a 4-20 mA standalone actuated control which is PC calibrated and able to remotely control any CLA-VAL
valve. The pilot setting can be adjusted with a standard 4-20 mA signal. It also incorporates a 4-20 mA position feedback
signal to cross check if the requested position is reached.

0-100% Calibration without System Pressure

The “Set range” allows calibration in either dynamic or static
mode. When the “Set Range” is clicked, the following mes­sage appears. If you would like to proceed with calibration,
click "OK", if not click "Cancel".

Initial preparation:

It is highly recommended that the valve and actuator as­sembly is isolated by closing upstream and downstream iso­lation valves and pressure is removed from valve. If this is
not possible, consult the factory. The objective is to remove
the site plug and visually determine the position of the “orifice

coupling” with respect
to the “stem tube”. They
should be flush with no
gap between the two
assemblies (see Fig.

1). The procedure for

Orifice coupling

this is shown below:

1. Isolate and remove pressure from the valve assembly.

2. Remove plug as shown in figure 1.

3. Open e-Drive / CPC Software then go to "Set Range"
tab and click OK on the menu.

4. Select "Static Calibration" Mode and check "CPC

Motor" box is checked and select trim size from the drop
down menu (3).

5. Using the "Increase actuator"/ "Decrease actuator"
Buttons, adjust the position of the “orifice coupling”
until there is no gap (flush) with the stem tube
(See Fig. 1)

6. Select the valve size to be calibrated from the drop
down menu (3) to determine the number of turns
required to achieve full opening of the valve.

7. Select units.

8. Enter 4 mA value and 20 mA value.

9. Turns to low point (1): Enter the number ‘1’.

Calibration - Variable Range

Calibration Mode to a specific process WITH System pressure.

Initial preparation:

This calibration mode is for field installations where water pressure is available and you want to control flow over a specific
range of positions.

Now you are in the calibration, please enter the required settings.

1. Select "Dynamic Calibration" mode and ensure that the "CPC Motor" check box is checked (Enabled).

2. Select units.

3. Enter the required setting Value at 4 mA point and Value at 20 mA point. Look at the position on the display and use

the "Increase actuator / Decrease actuator" button, until it reaches.

4. The low position point. When the low position point is reached click on the button "Low point setting".

5. Look at the position on the display and use the "Increase actuator / Decrease actuator" button, until it reaches
the high position.When the high position point is reached click on the button "High point setting".

6. When all values have been entered, click on "Write Set Range". Your calibration is done.

Page 9

Configuration

1. The configuration tab sets the Rotation speed and the Dead band.

2. The Rotation speed affects the response time of the valve between set-points.

3. The default condition is 0 seconds "On-time" and 0 seconds "Off-time" achieving continuous rotation speed which

will vary corresponding to the size of your valve.

4. Make sure that the values entered are appropriate to your system to minimize potential for surge.

5. Dead band - The default value is 0.1 mA which may need to be increased depending on the stability of the electrical
signal.

6. Choose the loss of signal mode.

7. Go to 4 mA: CPC will default to the 4 mA position (low set point).

8. Last position: CPC will maintain the last position.

9. Go to 20 mA: CPC will default to the 20 mA position (high set point).

Note: Loss of signal can occur on the SCADA system which generates the 4-20 mA command but at the same time the CPC

can stay powered, so it is important to select the right option. When you have finished your configuration, click on
"Write Configuration".

Your CPC is configured.

Alarms

The CPC incorporates a LOW and HIGH Alarm with an adjustable hysteresis setting. The low and High alarm levels
are activated within the range:

Example: 10% low alarm = 4 + (10% x 16) = 5.6 mA. 90% High alarm = 4 + (90% x 16) = 18.4 mA.

Hysteresis:

1. The calculation is: 4 + (2% x 16) = 0.32 mA.

Low alarm hysteresis in this example = 5.6 mA + 0.32 mA = 5.92 mA.
High alarm hysteresis in this example = 18.4 mA - 0.32 mA = 18.08 mA.

2. Enter the requested percentage, for the alarms and hysteresis.

3. Click on "Test" to close or open your contact relay.

4. Click on "Write Alarms" (1) once your alarm settings are correct.
