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 receiver/controller unit.
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.
All systems are CSA, CE, and FCC approved.
Pressing the Emergency Stop button causes the receiver/controller unit to trigger a plant 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 receiver/controller unit.
Optional Handheld E-Stop controls are ATEX approved for Zone 0 applications, and can be added to any system.
E-Stop Receiver/ Controller
Easily interfaced with electrical, pneumatic, nitrogen, or mechanical plant shut-off equipment.
Systems will operate with 12/24VDC or 120/240VAC power supplies.
Receiver/Controller outputs can specified as 12/24VDC, 120/240VAC, dry contact, RS232, or J1939 CAN bus.
BASE Engineering can also supply electric/pneumatic solenoids on request.
Standard receiver/controller units are NOT rated explosion proof and are typically installed in non-hazardous electrical control equipment areas. Receiver/controller units are provided with antenna and coax cable for outside antenna mounting providing maximum operating range. Explosion-proof electrical enclosures are available on request.
Fixed-frequency remote E-Stop switch operates at 433MHz using two double “A” batteries. 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. Operating range up to 1000ft.
*Daily E-Stop transmitter battery tests and scheduled battery replacement interval is strongly recommended. The E-Stop transmitters and receiver/controller shut-down will NOT operate when the remote E-Stop transmitter batteries are exhausted.
MODEL DSSF 100-AC
Direct sequence, spread-spectrum remote E-Stop switch operates at 2.4GHz using a rechargeable battery pack. The E-Stop switch and receiver/controller unit are connected via SafeLink – a continuous monitoring feature exclusive to BASE Engineering. Any loss of signal connection between the remote E-Stop switch and receiver/controller results in an automatic E-Stop trigger until the signal is restored. High powered E-Stop transmitters have an operating range of up to two miles. Transmitters must be connected to a back-up power supply as the battery pack will operate for only seven days. Back up power can be 12/24VDC, 120/240VAC, and solar powered where practical.
