Is anyone having problems with belimo actuators loosing controll, they usually go to 100% and stay there with no signal to drive. controll signal is 2-10 belimo series actuator is nvg,and nvf. Cycle 24 volt power to actuator and controll is immediately restored. I have clean power to the actuator, good controll signal to the actuator, these are on both chilled water and hot water as well as steam valves, they are failing on trane summit bcu's, Carrier controll systems, teletroll systems, and a honeywell stand alone proportional reset temp controll. Belimo's response is that they have no problem. My solution has been to break controll power once every 24 hours, this seems to prevent loss of controll.
