SED2 VFD Electronic Bypass Option Operating Instructions

Interlock and Auto Bypass on VFD Fault

Description

Interlock and Auto Bypass features are both active. Auto bypass now becomes auto bypass on a VFD fault only (bypass is initiated by the SED2 Fault and this digital output must always be programmed to VFD fault).

•All set-up is the same as with Interlock (see the Interlock section in Application Feature Setup).

•Hand bypass is now initiated by SED2 Fault.

•The Programmable Output is still used to initiate the proofing sequence.

Settings

Interlock and Auto Bypass requires that Controller board DIP Switches 2 and 3 are set ON.

NOTE: During operation, the Auto Bypass Enabled indicator is on steady. Also, the Interlock Start Logic Enabled indicator is on steady.
