VariPhase N Series - AirCare Automation - #1

Text version of the page

AirCare VariPhase ™ Overview This AC0yB14 is a “Network Only” version of the AirCare V-Series VariPhase™ line. Targeted at Fan Filter Unit (FFU) applications the unit offers 3-wire Phase-control speed conditioning along with a contact switch feedback for go/no-go fan monitoring and feedback. The AC0yB14 uses MODBUS®RTU network communication and is compatible with all the AirCare Console and System controllers. The AC0yB14 enables single-phase AC PSC motors to run at optimized speeds and reduce motor heating, energy consumption and audible noise. Features • Variable Voltage Phase-Control • 115V, 230V and 277V models • Up to 3 Amp load capability • 3-wire option reduces motor hum and increases efficiency at lower speeds • RS485 network connectivity (MODBUS RTU protocol) using either: o Twisted-pair cable. o RJ45 Connector • Monitoring input for pressure switch or similar open/closed contact switch. • Minimum Speed Set Point (register set) • Soft-start reduces motor start current • LED indicates board status Specification Summary • Automatic Selection of 50/60Hz • Simple connections o ¼” Spade terminals for power o ¼” Spade terminals for sensor fdbk. o 7 way terminal block or RJ-45 contacts for communications (optional) • LED diagnostics o Green – Board OK, valid comms link o Red – Fault, no comms link • Fuse Ratings o 5A 250V or 3A 300V • MODBUS RTU Protocol o RS485 9600,8,n,1 • Minimum speed set by MODBUS register • Open-frame PCB o Mount with standard nylon standoffs • 0-50°C operating temperature • Low-profile design o 3.95” x 3.95” x 1.0” Model Matrix Product Description AC0yB14 is an application specific Network only version of the AirCare VariPhase™ VSeries controller. Providing Open-loop control and NC/NO sensor switch contact, this unit is targeted at baseline Fan Filter Installations. AC0yB14 is very simple to install and configure. The only necessary electrical connections are an AC supply, a motor load and RS485 wiring. The Units MODBUS address is set from 1 to 240 using an on-board DIP switch. The motor load may be connected in standard two-wire mode, or with the auxiliary winding permanently powered in 3-wire mode (see wiring diagram). A dedicated spade-terminal is (AUX) provided. AC0yB14 feedback input (IN) can be wired directly to an external contact, such as a pressure switch or a motor thermal cut-off switch. Connecting an external NO/NC contact can be done through either the 7 way terminal block or ¼” Spade terminals mounted above the 7-way. This NO/NC input is comparable to the ANA1 input on standard VariPhase(s) units and can be used for monitoring go/no-go performance of a fan system (i.e. differential pressure switch monitoring).
