5 CrossCheck tm Control Reliable Double Valves for External Monitoring Operation Overview CC4 Series Conditions at Start: Pressure applied to port, but all solenoids off. All ports (,,, & 4) are blocked. B 4 A Sensing Midpoint INLET Port 4 Valve De-energized EXHAUST Normal Operation: Energizing both solenoids 4A & 4B causes the valve to shift and supply pressure to port 4 while exhausting pressure from port, thus, extending the cylinder. Conversely, energizing solenoids A & B causes the valve to shift and supply pressure to port while exhausting pressure from port 4, thus, causing the cylinder to retract. Turning all the solenoids off allows the strong return springs to shift the redundant valves back to the center position, which blocks all ports. This traps any downstream pressure in the cylinder and holds it in its current position (see below on the right, image of valve de-energized trapping pressure). Each of the mid-position feedback sensors provide a voltage output when the valve is in the center, safe position, but no voltage output when the valve internals are shifted out of the center position. This provides a detectable center position for both sets of valve internals. 4 B A Sensor B + 4 VDC Power + 4 VDC Common 4 Sensor A + 4 VDC Ground Abnormal Operation: When energizing, if both sets of valve internals do not shift synchronously (either on or off), the CrossCheck TM valve will block all ports. While in this fault condition, the valve cannot further pressurize or exhaust the cylinder lines. Also, as long as the fault condition exists, there will be a voltage output from the valve internals that did not shift from center, but there will not be an output from the other valve internals that did shift off center. This provides a detectable fault condition as both sensors need to agree in order to not indicate a fault.

Such a monitoring system must be capable of inhibiting the operation of the valve. The safety control system must de-energize the valve s solenoids in the event of a fault within the valve and/or within the safety control system, and check for achievement of the valve center position before allowing an attempt to re-energize the valve. Valve reset is accomplished by de-energizing all of the valve s solenoids. Reset of the safety control system should not occur unless the valve has fully returned to its center position (both sets of internals). The output voltage of the sensors, when switched on (center position), equals approximately the voltage supplied to the sensors by the safety controller. or example, 4 volts DC In = 4 volts DC Out, etc. 4 B A 4 B A Sensor B Sensor B Power 4 VDC 4 5 Common Power 4 VDC 4 5 Common Sensor A Ground Sensor A Ground B 4 A B 4 A Sensing Midpoint INLET INLET Port 4 Port 4 EXHAUST EXHAUST Trapped Pressure Release: In order to perform machine maintenance, after stopping the machine and performing lockout/tagout, pressure trapped in the cylinder by the CrossCheck TM valve can be released (exhausted) by the two manuallyoperated -way valves that are provided in the CrossCheck TM valve sub-base - one each per valve outlet port. This provides a way to slowly lower the cylinder to its lowest position. NOTE: Operating the manual trapped pressure release valves will cause movement of the cylinder. Use caution to avoid any hazards associated with this movement.

21 CAUTIONS, WARNINGS and STANDARD WARRANTY PRE-INSTALLATION or SERVICE. Before servicing a valve or other pneumatic component, be sure that all sources of energy are turned off, the entire pneumatic system is shut off and exhausted, and all power sources are locked out (ref: OSHA 90.47, EN 07).. All ROSS products, including service kits and parts, should be installed and/or serviced only by persons having training and experience with pneumatic equipment. Because any installation can be tampered with or need servicing after installation, persons responsible for the safety of others or the care of equipment must check every installation on a regular basis and perform all necessary maintenance.. All applicable instructions should be read and complied with before using any fluid power system in order to prevent harm to persons or equipment. In addition, overhauled or serviced valves must be functionally tested prior to installation and use. If you have any questions, call your nearest ROSS location listed on the cover of this document. 4. Each ROSS product should be used within its specification limits. In addition, use only ROSS parts to repair ROSS products. WARNING: ailure to follow these directions can adversely affect the performance of the product or result in the potential for human injury or damage to property. ILTRATION and LUBRICATION 5. Dirt, scale, moisture, etc. are present in virtually every air system. Although some valves are more tolerant of these contaminants than others, best performance will be realized if a filter is installed to clean the air supply, thus preventing contaminants from interfering with the proper performance of the equipment. ROSS recommends a filter with a 5-micron rating for normal applications. 6. All standard ROSS filters and lubricators with polycarbonate plastic bowls are designed for compressed air applications only. Do not fail to use the metal bowl guard, where provided, to minimize danger from high pressure fragmentation in the event of bowl failure. Do not expose these products to certain fluids, such as alcohol or liquefied petroleum gas, as they can cause bowls to rupture, creating a combustible condition, hazardous leakage, and the potential for human injury or damage to property. Immediately replace a crazed, cracked, or deteriorated bowl. When bowl gets dirty, replace it or wipe it with a clean dry cloth. 7. Only use lubricants which are compatible with materials used in the valves and other components in the system. Normally, compatible lubricants are petroleum based oils with oxidation inhibitors, an aniline point between 80 (8 C) and 0 (04 C), and an ISO, or lighter, viscosity. Avoid oils with phosphate type additives which can harm polyurethane components, potentially leading to valve failure which risks human injury, and/or damage to property. AVOID INTAKE/EXHAUST RESTRICTION 8. Do not restrict the air flow in the supply line. To do so could reduce the pressure of the supply air below the minimum requirements for the valve and thereby cause erratic action. 9. Do not restrict a valve s exhaust port as this can adversely affect its operation. Exhaust silencers must be resistant to clogging and must have flow capacities at least as great as the exhaust capacities of the valves. Contamination of the silencer can result in reduced flow and increased back pressure. WARNING: ROSS expressly disclaims all warranties and responsibility for any unsatisfactory performance or injuries caused by the use of the wrong type, wrong size, or an inadequately maintained silencer installed with a ROSS product. POWER PRESSES 0. Mechanical power presses and other potentially hazardous machinery using a pneumatically controlled clutch and brake mechanism must use a press control double valve with a monitoring device. A double valve without a self-contained monitoring device should be used only in conjunction with a control system which assures monitoring of the valve. All double valve installations involving hazardous applications should incorporate a monitoring system which inhibits further operation of the valve and machine in the event of a failure within the valve mechanism. ENERGY ISOLATION/EMERGENCY STOP. Per specifications and regulations, ROSS L-O-X and L-O-X with EEZ-ON operation products are defined as energy isolation devices, NOT AS EMERGENCY STOP DEVICES.
