ROSS safety-related technology has a long tradition... ROSS 5/2-way Double CROSSMIRROR®-Sensing For almost 40 years ROSS has been developing double valves which have made a significant contribution to the operating safety of pneumatically controlled presses. During this period our range of double valves has been developed continuously in response to the needs of press manufacturers and users. Monitoring devices have also been offered in a variety of designs to satisfy different requirements.

5/2-Way Double Valves with CROSSMIRROR®-Sensing GENERAL INFORMATION The new ROSS 5/2-way CROSS MIRROR® double valve is designed as a self-monitoring valve. It can be used for controlling pneumatic presses for coldforming of metal (optionally in connection with additional devices such as pilot-operated check valves), if the electric control of the valve is designed in accordance with prEN..."Pneumatic Presses" (June 1998).
5/2-Way Double Valves with CROSSMIRROR®-Sensing CAUTIONS Installation Double valves should be installed only by persons trained and experienced in the installation of such equipment. Lines Air supply directed through air preparation units and pressure regulator to pressure port 1 requires minimum line capacity of pressure port 1. Lines and line connections must be in accordance with relevant safety regulations, e.g. prEN... Pneumatic Presses“ (June 1998).
5/2-Way Double Valves with CROSSMIRROR®-Sensing OPERATING INSTRUCTIONS Start-up Prior to start-up, the installation must be checked thoroughly by persons trained and experienced in the operation of pneumatic equipment. Make sure that the maximum operating pressure specified on the valve label will not be exceeded. When operating pressure is applied, the cylinder piston must move into the atrest-position. For further testing, a functional test as well as a pressure failure test must be performed.

PRODUCT DATA SHEET INFORMATION 5/2 CROSSMIRROR® Series 77 Solenoid Pilot Controlled Pneumatic Double Valve Control Reliable Energy Isolation • Self-contained dynamic monitoring system requires no additional valve monitoring controls • • • • condition; MUST be integrated into machine controls in order to prevent run signal until fault is cleared in valve Applications include small size pneumatic cylinder-operated presses, valve operators, and safety latches Base mounted, stainless steel spool valve co
PRODUCT DATA SHEET INFORMATION This Series 77 5/2 CrossMirror® valve is a control reliable, two hand pressure controlled 4-way double valve that is controlled by two separate pneumatic signals essentially providing “AND” gate control for the output ports. Both pilot signals must be provided within approximately 500 milliseconds of each other to actuate the valve. Proper actuation shifts output pressure to port 4.

ACCESSORIES ELECTRICAL CONNECTORS Electrical connectors are required to connect the valve solenoids to the drop cords supplying electrical power. Each connector can be positioned so that the cord exits upward or to the side. Cords of 6 mm to 10 mm diameter can be used. Connectors with a light in a translucent housing are also available to serve as indicator lights. Order connectors by the part numbers given in the chart below. WIRED CONNECTORS have a 2 meter (61/2 ft) cord with three 18 gauge conductors.
