At start-up, the LED remains red for 5 seconds, then switches to solid Green.
•
Green
Status OK.
•
No light
Check power supply.
•
Red
Exceed the High torque limit - Power down and power up again. If problem persists contact CLA-VAL.
Excess Voltage (Above 32 V).
•
Blinking red/green
Calibration was not completed correctly - recalibrate.
•
Changing a set-point without a command signal with a CPC - USB cable connected
1. Calibrate your range.
2. Select ‘Last position’ in loss of signal mode.
3. Go to ‘Display’ tab, select your Milliamp value and tick the check box to activate.

` CPC CHARACTERISTICS
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 together with 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.

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:
LIN040UE-03
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.
4- Look at the position on the display and use the "Increase actuator / Decrease actuator" button, until it reaches
the low position point. When the low position point is reached then 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 point. When the high position point is reached then click on the button "High point setting".

the low position point. When the low position point is reached then 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 point. When the position does not increase any more then stop the actuator. Decrease the
position by a small amount, as soon as you see the display changing stop again.
6- Enter the indicated value in the projected calibration window "Attainable high point value" as described above,
then click on "High point setting".
7- When all values have been entered, click on "Write Set Range".

CONFIGURATION
The configuration tab sets the Rotation speed and the Deadband.
•
The Rotation speed affects the response time of the valve between set-points.
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.
Make sure that the values entered are appropriate to your system to minimise potential for surge.
•
Dead band - The default value is 0.1 mA which may need to be increased depending on the stability of the
electrical signal.
Choose the loss of signal mode.
•
Go to 4 mA:
CPC will default to the 4 mA position (low set point).
•
Last position:
CPC will maintain the last position.
•
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.
Note: 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:
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.
Enter the requested percentage, for the alarms and hysteresis.

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