The RKI Emergency Stop (E-STOP) system is a versatile emergency stop device that can be activated either manually or by the activation or deactivation of a relay on a gas detection controller or other device. A highly visible, clearly marked push-button can be pressed to stop a process or shut off a valve, or the same action can occur automatically by the opening of relay contacts in a controller which the E-STOP can be connected to. To restart the process or re-open the closed valve, the E-STOP push-button can be turned clockwise to reset. It can also be reset by the gas alarm condition clearing and resetting its alarm relay, either by auto reset if desired, or by manual reset of the gas alarm or other alarming device.
There are 2 styles of E-STOP available; one with a relay that can be used to activate an external valve or process, and another that has a self draining pneumatic valve which can be used to open or close an external valve. Both styles are available in either a 24 VDC version or a 115 VAC version. All are provided inside a wall mounting NEMA 4X enclosure so they can be installed in a harsh environment.
The E-STOP had a large red and green light stack mounted on top. The green light will be on if the E-STOP is operating properly and is not activated. The red light will activate if the E-STOP button is pressed or if an external controller has activated a shutdown.
The E-STOP represents the latest leading edge technology in fixed gas detection today.
