TC-IDD321 Honeywell Controller module Brand new

In this table, three different I/O connectors have references as J5, J6, and J7. The UIO channels

OUT1 through OUT12 are connected to the I/O connector J5. The UIO channels OUT21 through

OUT32 are connected to the I/O connectors J6. The Basic Controller IO points are listed in the first

column and the corresponding UIO channel names are listed in the second column.

ATTENTION

l The spare channels are connected to the I/O connector J7.

l UIO channels mapped to the TCBxx terminal panel must be configured in Control

Builder to the IO type as defined in the table "Mapping the UIO channels to the I/O

connectors."

7.4 Checklist for system and grounding audit of TDC 2000

system

The checklist for each components of TDC 2000 system is explained here.

7.4.1 Cabinet

1. Examine the integrity of all external cabinet sides to ensure that AC Safety Ground is

maintained on all metal surfaces.

2. Verify the connectivity between the chassis ground reference point (or bar) and all metal

surfaces using an ohmmeter. For a properly connected system, you can see a resistance of

less than 1 ohm for all points (remember to subtract out the resistance of the meter wires).

3. Check the local master reference bar (the large copper bar at the top of the Basic cabinet) for

corrosion and loose connections.

4. Inspect the vertical bus bar system (if present) and then check all three bars for corrosion
