SED2 VFD Electronic Bypass Option Operating Instructions
VFD0108R1
Pushbutton/Indicator | Description |
| When the Interlock DIP switch is enabled, the Interlock Start Logic Enable |
| indicator is on steady. Any call to start the motor in either VFD or bypass |
| modes will not start the motor; instead it will close the Programmable |
| Output relay on the Controller board. |
| The Programmable Output can be used to actuate another device. When |
INTERLOCKSTARTLOGIC Enable Commanded Proofed | this occurs, the Interlock Start Logic Commanded indicator also lights, |
| and the Interlock Start Logic Proofed indicator flashes. |
| A contact closure from this other device is wired to the Interlock Start on |
| the Controller board which then starts the motor and turns the Interlock |
| Start Logic Proofed indicator on steady. This feature is also called |
| damper end switch relay logic. |
