Many units also have a second solenoid operated shutdown device that is usually identical to the emergency shutdown solenoid. It may be used as a normal shutdown solenoid or a speed no load solenoid. If it is used as a normal shutdown device, its operation will still close the wicket gates, but unlike the emergency shutdown solenoid, it does not need to be reset manually. A speed no load solenoid typically moves the gate limit to some value just above the speed no load gate position. The speed no load solenoid is usually tripped during startup and. | GUIDE RG-597 safety Prevention of mechanical hazards Fixed guards and safety distances CSSĨ M safety Prevention of mechanical hazards Fixed guards and safety distances Research and writing Laurent Giraud Ph.
