Transcription

1 B350L, 3-Way, Diverting Ball Valve hrome Plated Brass Ball and Nickel Plated Brass Stem pplication This valve is typically used in air handling units on heating or cooling coils, and fan coil unit heating or cooling coils. Some other common applications include Unit Ventilators, VV box re-heat coils and bypass loops. This valve is suitable for use in a hydronic system with variable or constant flow.

4 Wiring Diagrams INSTLLTION NOTES Provide overload protection and disconnect as required. ctuators may be connected in parallel. Power consumption and input impedance must be observed. ctuators may also be powered by 4 VD. Only connect common to negative (-) leg of control circuits. 500 Ω resistor (ZG-R0) converts the 4 to 0 m control signal to to 0 VD. ontrol signal may be pulsed from either the Hot (Source) or ommon (Sink) 4 V line. For triac sink the ommon connection from the actuator must be connected to the Hot connection of the controller. Position feedback cannot be used with a triac sink controller; the actuator internal common reference is not compatible. IN4004 or IN4007 diode. (IN4007 supplied, Belimo part number 4055). ctuators with plenum cable do not have numbers; use color codes instead. Meets culus requirements without the need of an electrical ground connection.! WRNING! LIVE ELETRIL OMPONENTS! During installation, testing, servicing and troubleshooting of this product, it may be necessary to work with live electrical components. Have a qualified licensed electrician or other individual who has been properly trained in handling live electrical components perform these tasks. Failure to follow all electrical safety precautions when exposed to live electrical components could result in death or serious injury.
