  • Page 3: Introduction

    Introduction ROSS Controls offers a variety of safety valves for use in various safety functions such as safe exhaust, safe cylinder return, and safe cylinder control/stop (load holding). This document focuses specifically on ROSS Controls’ 4/3 CC4 Series valves that are used for safe cylinder control/stop functions and utilize magnetic proximity sensors (PNP) to provide feedback to a safety control system for external monitoring.

    Once a fault is detected, the safety control system should turn off the outputs to all the valve solenoids. See Loss of Supply Pressure While Actuated on page 6. WARNING: A loss of supply pressure to the valve and cylinder could cause unexpected cylinder movement. ROSS CONTROLS © 2019, ® . All Rights Reserved.
  • Page 5 CC4 Series Valves Integration Guide In order to convert the CC4 valve to external pilot supply: A. Shut-off and exhaust all pressure from the system and disconnect all electrical power from the valve. B. Remove the cover from the valve (2 screws). See photo below (left). C.

    • Receipt of signals at solenoids not synchronous • Pilot valves experiencing a switching delay due to damaged components, dirt, debris or resinous oil • Excessive water build-up in the valve ROSS CONTROLS © 2019, ® . All Rights Reserved.

  • Page 7: Feedback Monitoring (General)

    CC4 Series Valves Integration Guide Feedback Monitoring (General) The CC4 valve is equipped with feedback proximity sensors that must be monitored by the user’s external safety control & monitoring system to detect fault conditions within the valve. Sensor feedback should always be opposite the solenoid actuating signals. In other words, when the solenoids are energized, the sensor outputs should be off and when the solenoids are de-energized, the sensor outputs should be on.

    Actuation Fault Monitoring logic. WARNING: Valve does not close due to loss of supply pressure until the supply pressure drops below 60 psig (4 bar) which could result in unexpected cylinder movement. ROSS CONTROLS © 2019, ® . All Rights Reserved.

  • Page 9: No Supply Pressure Applied Before Actuation

    CC4 Series Valves Integration Guide Operation & Monitoring – Loss of Supply Pressure While Actuated (continued) Using EXTERNAL Pilot Supply (Optional configuration): When operating the CC4 valve with EXTERNAL pilot pressure (supplied externally from a separate source through the X port), a loss of supply pressure in supply port 1, but not in external pilot supply port X, will allow the valves to remain actuated;...
