Click&Go ApplicationClick&Go Application Guidebook - 19677 Application 5ioLogik E2214Reducing Downtime in a Runway Security SystemProject BackgroundRelay control for lighting and motion detection is at the heart of a runway perimeter intrusion detection and alarm system application. On a typical day, aircraft constantly come and go on both the runway and adjacent taxiways, creating a dangerous environment for anyone or anything entering the runway. For this reason, installing a stand-alone, remote control system for intrusion detection and issuing alarms is an absolute necessity for avoiding accidents.Application RequirementsBesides motion sensors, alarm lights, and a second-tier (external) relay board, a remote controller is the most important component inside the device cabinet. Programming power on the controller should be available to perform the local control. At the same time, the relay components on a second-tier relay board should be replaced in advance to avoid failures when they wear out. On average, the relays can be used 25,000 times, but should be replaced after being used 10,000 times to avoid unexpected failures. The local controller not only controls the on/off functions of the alarm lights when the sensors are activated, but is also required to send a warning when the usage of a specific channel of the second-tier relay board reaches 10,000 times.Moxa’s SolutionThe ioLogik E2214 is designed with 6 DI and 6 relay channels. With the user-friendly Click&Go local control logic, users can easily program the ioLogik E2214 as the front-end relay controller to detect intrusions. Click&Go also supports a special function called ‘’relay counter storage’’ to provide readings of the current relay usage. This allows the ioLogik E2214 to send out TCP packets to the central SCADA system and a warning e-mail at the same time so that site maintainers can replace the relay components of the second-tier relay board. After the replacement, site maintainers simply press the RESET button attached to the ioLogik E2214 to clear the counts. In other words, there is no need to use laptop computers or remote commands. 18 |
