2.7.2 Check #2: Rotation on Bypass power NOTE: This operation will start the motor across the line. Place the electronic bypass in the Bypass Mode by pressing the BYPASS pushbutton on the electronic bypass keypad. The BYPASS LED will light. Press the HAND button on the electronic bypass keypad. -
Page 16: Section 3 - Operation
Section 3 - Operation WARNING Precautions: 1. Motor rotation MUST be checked in both VFD and Bypass Modes. Failure to confirm rotation may cause severe damage to the electronic bypass, motor or its driven equipment. 2. Only turn ON the input power supply after closing the front door. 3. -
Page 17: Vfd Keypad
The keypad on the VFD is primarily used for speed control in Hand Mode and monitoring purposes as limited programming is required to operate the electronic bypass. See the “HVAC Drive H300 Installation & Commissioning Guide”, “Unidrive M200/M201 User Guide” or the “Unidrive M400 User Guide” for detailed programming information. -

Page 24: Using The Electronic Bypass Configuration Switches
4.3 Using the Electronic Bypass Configuration Switches The bypass configuration switches are a group of four switches that are used to tailor the following: Automatic Bypass Fire Alarm Damper Control Fireman’s Override Note: “ON” disables function Switch 1: Enables or disables the automatic bypass function. With switch 1 in the ON position and the electronic bypass package operating in VFD Mode, a VFD fault will cause both the operation and run modes to be canceled (stopping the motor) and the VFD FAULT LED to illuminate in the Alarm Display. -
Page 25: Using The Additional Customer Inputs
“damper feedback” contact closed (TB3-3) within that time to prevent the bypass controller from “faulting” and preventing motor operation. The bypass keypad will annunciate the faulted condition by flashing one or more of the button status LEDs that happened to be on at the time of the fault. The bypass controller can be reset by cycling the customer reset input, which will reset the 120 second timer and retry motor operation. -
Page 26: Motor Overload
Remote bypass input (TB3-1): can be used to override the keypad selections and force the electronic bypass into Bypass Mode from an external contact. Once this signal is removed, the electronic bypass will not return to its previous mode of operation without keypad interaction. -
Page 27: Vfd Mode
To exit the Test Mode, press the OFF/RESET button on the electronic bypass keypad. The VFD input contactor will open and the TEST and INPUT CONTACTOR LEDs will go out. 4.7.2 VFD mode In VFD Mode both the input and output contactors are energized. A Start command must exist before the VFD can operate. -
Page 28: Auto Mode
4.7.5 Auto Mode In the VFD Auto (automatic) mode, a building automation system or other external device is required to supply start/stop and speed reference information to the electronic bypass package. During Auto Mode operation, the electronic bypass keypad remains enabled for stopping, operation mode and bypass selection functions. -
Page 29: Automatic Bypass On Vfd Fault
4.8.2 Automatic Bypass on VFD Fault In the Automatic Bypass on VFD Fault Mode of operation, when the electronic bypass control board senses a VFD fault it will automatically switch the motor to Bypass operation. This function is enabled by DIP switch 1, position 1, placed in the OFF position. -
