Plant About a week later the web server was checked remotely to attempt and display the weekend s data but no connection to the web server could be made After a visit to the Pre Treatment Plant it was found that the industrial Velcro glued to the back of the gateway had become detached from the PVC backing board and was hanging by its ethernet cable When the gateway fell it hit and damaged one of the water valves directly beneath it and hence had a constant slow dripping of water from the valve and into the input comms side of the gateway Luckily the power connector was disconnected when the unit fell and so the gateway was not powered and hence might be recoverable So in an effort to save the gateway all connections were detached and sensors turned off so they would not continuously poll the gateway and lose battery life Most of the water in the gateway enclosure was removed by spraying it with compressed air It was then put inside a dehydrating oven at 35 C for approximately four hours After four hours the gateway was tested and still functioned correctly The gateway was taken back to the Pre Treatment Plant Page 35 Chapter 3 Dialysis Reverse Osmosis Monitoring System Installation and temporarily attached via cable ties to existing pipes until the proper gateway bracket arrived Another problem was encountered when there was a system failure in the Pre Treatment Plant as a result of the Break Water Tank emptying the
