Yaskawa E7L Drive Bypass - Manual (Page 81)

Start Up and Operation 4 - 3
The BAS Interlock Circuit at Power Up
When a Run command is received in HAND or AUTO mode, the E7L will display a red “Damper/Bas” LED in the “System
Status” area of the front control panel. This condition will prevent Drive or Bypass operation.
One of the following three items needs to be done prior to start-up:
1) Install a “BAS Interlock Circuit” between TB1-3 and TB1-9 on PCB A2.
2) Install a jumper between TB1-3 and TB1-9 on PCB A2. This method should be used if a “BAS Interlock Circuit” will be
added later in the installation.
3) De-activate these terminals by moving DIP switch S2-8 to the ON position (toward the enclosure door). This solution is
only suggested if a “Safety Circuit” will never be applied to the drive system.
