ASKF Fixed Location
ASKF Fixed Location
Our combination wireless and fixed location E-Stop / emergency shutdown systems were developed to eliminate costly hard wiring of multiple fixed location emergency stop switches. Any number of wireless remote E-Stop switches can be installed within the plant facility and communicate with one or more receiver/controller units.
These systems will work in conjunction with existing, hard-wired, manual E-Stop switches and plant safety controls. Operator worn E-Stop remotes can also be added to these systems.
overview
Pressing the Emergency Stop button causes the receiver/controller unit to trigger a shut down. The system cannot be rebooted until the E-Stop button is pulled out and a manual receiver/controller reset is performed. E-Stop buttons are dual contact - dual channel, and comply with global E-Stop switch requirements. Systems will fail safe, triggering an automatic E-Stop with any loss of main line electrical power supply to the main receiver/controller unit.
Fixed frequency remote E-Stop switch operates at 433 MHz using two double “A” batteries. The transmitter is energized only when E-Stop switch is activated. Battery Test button shows a '“low battery” flashing LED on the E-Stop switch as well as on the receiver/controller unit. A “low battery” alarm or indicator lamp output is supplied for auxiliary low battery warning. Typical battery life is one to two years, but routine battery testing and replacement is recommended. Typical operating range up to 1000ft.
