3/2-Way Double Valves with CROSSMIRROR® Monitoring

Product catalog summary

Introduction
The document introduces ROSS's advancements in safety technology, focusing on the 3/2-way double valves with CROSSMIRROR® monitoring system, designed for pneumatically controlled presses to enhance safety features.

Specifications
The CROSSMIRROR® valves are available in sizes 4 and 8, featuring a 3/2-way poppet design with Viton seals, suitable for compressed air. They operate at pressures between 3 to 8 bar and temperatures from 4°C to 80°C. The valves include dynamic internal monitoring and support various standard voltages.

Procedures and Operation
The valve locks out if elements shift asynchronously or if air pressure is lost, requiring an external reset signal. It is self-contained, with an optional pressure switch for lockout indication.

Safety and Compliance
The valve complies with EN 692:1996, EN 983:1996, and EN 954-1:1996 standards, ensuring high safety levels for pneumatic systems.

Installation and Maintenance
Installation should be done by trained personnel, ensuring efficient air filtration and adherence to electrical safety regulations. The reset valve should be momentarily actuated.

Conclusion
The ROSS 3/2-way double valves with CROSSMIRROR® monitoring offer a reliable safety solution for pneumatic press operations, meeting international safety standards.

Operating Instructions

Start-up: Ensure installation checks by trained personnel, matching valve specifications with press requirements. Actuate the reset valve to stand-by condition.
Functional Test: Actuate solenoids a and b within 200 ms for proper operation. Delays require a reset.
Pressure Failure Test: Use the reset valve to return to stand-by after malfunction.
Malfunctions: Pressure differences over 200 ms cause shutdown, often due to faulty seals or delayed response.

Maintenance and Repair

Follow national safety guidelines for maintenance, with annual checks recommended. Use original ROSS parts for repairs.

Cautions

Warranty: One-year warranty against defects, voided by misuse or improper maintenance.
Pre-Installation/Service: Ensure energy sources are off before servicing, performed by trained personnel.
Filtration and Lubrication: Use a 5-micron filter and compatible lubricants.
Intake/Exhaust Restriction: Avoid restricting air flow to prevent erratic valve action.
Double Valves: Use monitoring devices in hazardous applications.
Energy Isolation/Emergency Stop: ROSS L-O-X® products are for energy isolation, not emergency stops.

?On first operation or after the main air supplyhas been removed, the pilot valve supply circuit and inherent monitoring elements must be pres-surised by a momentary signal to the reset valve.The valve will then be ready for operation.?The air supply to each pilot valve is controlled by aspecial concentrically grooved poppet on each mainvalve element. In the ready for operation positionthese poppets are held on their seats and maintain pilot air flow. During shifting of the valve elementsthe poppets momentarily move off seat and allow pi-lot air to escape to exhaust. If either valve elementfails...

Start-up Before start-up, the installation must be checked thoroughly by persons trained and experienced in the operationof pneumatic equipment. Make sure that specifications given on the valve label (e.g. max. operating pressure)will be in accordance with the operating specifications of the press. When operating pressure is applied, the reset valve must be actuated in order to move the valve into the stand-by condition.If the valve is equipped with a pressure switch and a related fault indication as well as a stand-by indication,the fault indication extinguishes, and the stand-by indication...

PRE-INSTALLATION or SERVICE 1. Before servicing a valve or other pneumatic component, besure that all sources of energy are turned off, the entire pneu-matic system is shut off and exhausted, and all power sourcesare locked out (ref: EN 1037).2. All ROSS products, including service kits and parts, should beinstalled and/or serviced only by persons having training and ex-perience with pneumatic equipment. Because any installationcan be tampered with or need servicing after installation, per-sons responsible for the safety of others or the care of equip- ment must check every installation on a...
