Safety of Receiver Operation
The system has an explosion-proof casing and inner electronic circuit safe solution and it meets ATEX rules and strictly complies with explosion-proof standards. The emergency stop circuit and control with duplex redundant and safety relay with forcibly guided (mechanically linked) contacts make it meet the E-stop class Gat.3 in The European mechanical equipment standard. To ensure safety, continuous wireless communication devices make the receiver stop passively when the radio signal is disconnected or is interfered with. Buttons can be programmed to interlock to avoid opposite operations.
