baylys-SAF Posted February 23, 2018 Report Share Posted February 23, 2018 This post might turn out to become an extended series but here is No1...... By the way, what are Tags ? How are they used on this forum.? We own a camping ground. We had no choice but to install an treatment plant for the camp sewage effluent. The plant(SAF) has been in operation since December 2016, the controller PLC is a JZ10-11-UA24. In consultation with the design engineer we have written a manual which outlines all critical maintenance of the various aspects of the plant. All but except for the Controller componants! 1. In reading info on the Jazz PLC, I see there is an internal battery which has an approx. life ten years. If in years to come someone happened turn the main power off or simply power failure and was unaware the internal battery had expired a week before, I have a feeling there would be a problem. - true or false 2. If 1. is true then I need to keep a copy of the PLC U90 software? 3. The JZ-PRG plug in module and software kit, allows the software, OS etc to be copied to a PC? 4. After 10 years will the JZ10-11-UA24 PLC be out of date? If so, would it be a good plan to check this every 5 years ? Thanks, mark Quote Link to comment Share on other sites More sharing options...
