Description

Closed: BIP 1 is Normal (no diagnostic)

Open: BIP 1 is Active (diagnostic)

Closed: BIP 2 is Normal (no diagnostic)

Open: BIP 2 is Active (diagnostic)

Closed: BIP 3 is Normal (Occupied)

Open: BIP 3 is Active (Unoccupied)1

Open: BIP 3 is Normal (Occupied)

Closed: BIP 3 is Active (Unoccupied)1

When the controller commands the fan on and the binary input remains open for one minute, BIP is normal (diagnostic).

When the controller commands the fan on and the binary input closes, BIP is active (no diagnostic).

When input is Open, BIP is Active (Defrost activated)

When input is Closed, BIP is Normal (no Defrost)

De-energized: Fan off

Energized: Fan high

De-energized: Fan\Exhaust off

Energized: Fan Medium\Exhust on

De-energized: Fan off

Energized: Fan low

De-energized: Output off (de-energized)

Energized: Output on (energized)

1.The occupancy input applications vary for standalone and communicated instances. For more information, see Occupancy arbitration tables in the Appendix.

2.The fan status device is normally closed during normal fan operation. When the fan is off either from a fan failure or the controller commanding the fan off, the binary input device opens.
