[QUOTE="Phoenix, post: 392471, member: 8133"] Cool, thanks for the information :) While we are on the subject of school CDT rooms... I understand its perhaps not straight forward, but what level of emergency stopping is generally required, most I've seen just have a latching contactor arrangement. Nothing fancy with safety relays, dual contacters, aux contacts to detect jammed contacters, that you get in some R&D labs, etc. Then again I did see a joinery shop where the shop em system removed power to the machine tools board and prevented the braking systems from operating :red card [/QUOTE]
