Product Description
The HV600 bypass provides a way to bypass the drive and allow the motor to operate directly from the AC line at full
speed. It incorporates an AC drive and a two or three-contactor bypass arrangement in a single UL listed enclosure.
The two electrically-interlocked IEC-rated contactors isolate the drive from the load when operating in Bypass Mode.
Control logic provides industry standard Hand/Off/Auto functions, BAS Interlock, and safety circuit interlocks in
both Drive and Bypass operating modes.
Bypass components include: a fused 120 Vac control circuit transformer, an input disconnect, motor overload, DC
link choke, EMC filter, and an HOA keypad with LCD display.
The HV600 drive, a component of the bypass package, is a pulse width modulated drive for three-phase AC induction
motors. This type of drive is also known as an adjustable frequency drive, variable frequency drive, AC Drive, AFD,
ASD, VFD, and inverter.
The drive is a variable torque AC drive, designed specifically for HVAC applications in building automation,
including fans, blowers and pumps.
The bypass has embedded communications for the popular building automation protocols, BACnet and Modbus®.
The LCD keypad is equipped with Hand/Off/Auto functions. Optional DriveWizard software allows upload/
download, as well as graphing and monitoring of drive parameters from a PC for ease of drive management.
Built-in PI control eliminates the need for closed loop output signals from a building automation system. It includes
feedback display, inverse, square root and differential control functions, and maintains setpoint for closed loop control
of fans and pumps for pressure, flow, or temperature regulation. There is also an additional independent PI control for
external devices.
