Clippard CORDIS SERIES CP1 Dynamic Electronic Pressure Controls Instruction Manual

Clippard CORDIS SERIES CP1 Dynamic Electronic Pressure Controls

Product Information

The Cordis Series CP1 Dynamic Electronic Pressure Controls are known for their reliability, innovation, and focus on miniature pneumatics. These pressure controllers utilize the EVP and DVP proportional valve series to provide precise, linear pressure control within a closed-loop system. They offer ultra-high resolution and repeatability, ensuring steady, accurate, and repeatable downstream pressure control even as demand or process changes.

Key Features:

• Precise, linear pressure control within a closed-loop system
• Ultra-high resolution and repeatability
• Utilizes EVP and DVP proportional valve series
• Reliable and innovative
• Suitable for miniature pneumatics

Product Usage Instructions

Mounting:

The Cordis series can be mounted in any orientation without negatively affecting process control.

Pneumatic Plumbing:

Ensure that the regulated supply pressure is connected properly.
The process to be controlled should be connected to the appropriate port. Refer to Fig:1 for a visual representation of the pneumatic plumbing.

Safety & Best Practices:

• Recommended filtration for supply media is 40 micron or better.
• Regulate the supply pressure to the maximum pressure allowed for the calibrated range (refer to Table:2 & 3).
• If the supply pressure is not connected, disconnect the power.
• The inlet pressure must be at least 10% above the maximum calibrated range of Cordis to achieve maximum output.
• Always handle exposed circuit boards with precautionary measures: hold the circuit board on the edges to avoid damage.
• Store the device in an antistatic bag to prevent possible electrostatic discharge (ESD) damage.

Calibration:

The Cordis series is calibrated at the time of manufacture to NIST traceable standards. Each unit is calibrated and the PIDs (Proportional-Integral- Derivative) are set to the Cordis standard tuning. If the customer’s specific application details are known prior to manufacture, the PIDs will be tuned according to those specifications to provide stable and repeatable control.

Operating Instructions

Precise, linear pressure control within a closed-loop system with ultra high resolution and repeatability

• Known for reliability, innovation and focus on miniature pneumatics, Clippard’s Cordis Pressure controllers utilize the proven EVP and DVP proportional valve series allowing for steady, accurate and repeatable downstream pressure control as demand or process changes. The result, a very precise linear pressure control within a closed-loop system providing ultra-high resolution and repeatability.
• The Cordis uses a microcontroller, an internal or external pres-sure sensor, and a Clippard proportional valve. The inlet valve is connected to the moderately regulated supply pressure. Once a command is increased, the proportional valve opens up to allow supply pressure to pass over the sensor element which provides an active feedback for the microcontroller to satisfy the set point in the process. If at any point the sensor detects a value higher than the set point, the proportional valve closes and allows process to consume the remaining downstream pressure.

Operational Description

The Cordis is designed to accept a pressure on the inlet port, and control to a user-specific set pressure on the work port. The CP1 contains a microcontroller, integrated pressure sensor, and a Clippard EVP/DVP proportional valve.
For Cordis to control pressure in your process, a regulated supply pressure should be connected to the inlet valve (I). The outlet valve (O) should be connected to the downstream process. As the command signal increases the inlet valve opens to allow pressure downstream. This pressure passes over the internal sensor element which is constantly providing active feedback to the microcontroller. As soon as this feedback matches the user-specified command, the inlet valve closes and holds the commanded pressure downstream. If dynamic conditions exist or if any consumption occurs downstream, the inlet valve will open and instantly compensate to maintain the desired downstream setpoint.

Mounting

The Cordis series can be mounted in any orientation without negatively affecting process control.

Pneumatic Plumbing

Safety & Best Practices

• Recommended filtration for supply media is 40 micron or better.
• Supply pressure must be regulated to ≤ max pressure allowed for calibrated range. See Table: 2 & 3
• Disconnect power if supply pressure is not connected.
• Inlet pressure must be a minimum of 10% above max calibrated range of Cordis to achieve max output. Always take precautionary measures while handling exposed circuit boards: Hold circuit board on edges whenever handling device. Store device in antistatic bag to prevent possible ESD from damaging

Calibration

The calibration of the Cordis series is done at the time of manufacture to NIST traceable standards. Each unit is calibrated and the PIDs are set to the Cordis standard tuning. If a customer’s specific application details are known prior to manufacture (recommended), the PIDs will be tuned in accordance with the known specifications to provide the most stable and repeatable control. Below are the available calibration ranges and maximum allowed inlet pressure for each range.

Recalibration

The Cordis series does not require recalibration during its lifetime. If the calibration needs to be changed and/or modified, the unit must be returned to Clippard or completed by a certified field technician. Any attempt to recalibrate in the field without prior authorization will void the warranty.

0 to 10 VDC Electrical Connection

Make sure AC power is disconnected before DC connections are made
The Cordis requires 15 to 24 VDC on Pin 1 of the electrical connector. It uses 0 to 10 VDC command signal on Pin 3 of the electrical connector. The power supply ground, command source ground and Pin 2 must be tied together. If the analog monitor signal is being used, utilize Pin 4 to send the 0 to 10 VDC signal to a measuring device like a volt meter, panel meter or acquisition device.

Flow & Valve Selection Notes

Max flow assumes a P1 value of (at least) 10% above max pressure listed. Ex: a max pressure out of 50 psig assumes a min P1 value of 55 psig.
