u Product Description
The P1000 Bypass provides a means of bypassing the drive while allowing the motor to operate at full speed, directly from
the AC line. It incorporates an AC Drive and a three-contactor bypass arrangement in a single UL listed enclosure. The two
electrically interlocked IEC rated drive output and bypass contactors isolate the drive from the load when operating in Bypass
mode. An IEC rated drive input contactor also isolates the drive from the line 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, drive input fuses, motor overload, and an HOA
keypad with LCD display.
The P1000 drive, a component of the P1000 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 fans, blowers, and pumps.
The P1000 Bypass has BACnet and Modbus® embedded communications.
The LCD keypad/operator 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. An additional independent PI control is also provided for external devices.
