used as a supply voltage for user-supplied switches and accessories. For this 3-wire daisy chaining application, the downstream fan
controllers must be switched to Sinking (NPN) operation. Terminal 4 will then provide a DC common connection and allow the analog
signal and start stop signal to share that common.
The Assertion Level Switch above terminal 4 must be switched from (+) to ( - )
on all downstream fan controllers for proper daisy chaining operation prior to powerup, parameter changes and operation.
