BT300 HVAC Drives Electronic

Bypass (E-Bypass) Options

Siemens Industry, Inc.

Description

The BT300 Electronic Bypass (E-Bypass) Options are

companion packages for the family of BT300 Variable

Frequency Drives (VFDs).

For information on the family of BT300 VFDs, see the BT300

HVAC Drives Submittal Sheet (154-126), and BT300 HVAC

Drives Technical Specification Sheet (149-711).

BT300 E-Bypass Features

• Bypass Start-up Wizard

• Multiple Safeties

• Monitor and display which safety interlock is open

• Control external devices via serial communication

• Pass through I/O capabilities command up to 8 output

points

• View status of I/O points

• Supports APOGEE P1, BACnet and Modbus protocols

in bypass

• IBC 2012 Seismic Certified

• OSHPD Certified

• Compact design

E-Bypass Power Features

2-Contactor: Output and Bypass

• Overload protection in bypass mode

• Electrically interlocked

Drive Isolation

Drive Service Switch allows the drive to be disconnected

from power during troubleshooting without disrupting bypass

operation.

Input Device

• Disconnect with fuses.

• (Optional) Circuit breaker.

• All doors are interlocked and can be padlocked

5% Input Impedance

• Internal reactors lower harmonics that the drive

produces.

• BT300 E-Bypass requires no additional input reactors

E-Bypass Control Features

Auto Bypass

• Relay logic allows the user to send the motor to bypass

mode based on the drive’s programmable fault list.

• Customer defines the events which will transfer to

bypass.

• The drive’s programmable relay can be set up for

applications that run full speed for an extended period

of time.

Damper Interlock

• Generally used for safety tie-ins; the motor will not

operate the drive or bypass when open.

• Enables a circuit signaling the system is ready for

bypass.

Essential Service Mode

• Also used for smoke purge; the motor goes to bypass

regardless of the selected mode.

• No call to stop will have an effect, including open

safety or stop commands.

• Only turning the power off or opening this contact will

stop the motor.

Remote Bypass

Customer-supplied start/stop controls when running in

bypass.

Electronic Override

• Full bypass control, even if the control module

(intelligence) fails. As long as power is supplied to the

bypass, you have full bypass capability.

• Maintains all system safeties in bypass.
