Links
Links 1 to 6 are not used in this configuration and should be fitted in position B or removed.
Links 1 to 5 wire power from each group to the unused TBSS terminals 2 and 7. Link 6 wires TBSS
terminals 1 and 6 to zero volts. SmartSlot operation is no longer performed on the VFTA and therefore
the links should not be fitted.
Each channel has a set of links to configure the conditioning circuit, as referenced on the previous
pages. These are detailed below.
Links F1 to F8
Links E1 to E8
Links D1 to D8
Links C1 to C8
Links B1 to B8
Links A1 to A8
Figure 12 Link Detail (for first group)
Note: The pitch and spacing of the links prevent invalid configuration if the fuses supplied with the
VFTA are used.
Groups 2 to 5 are arranged in the same way. The channel links are numbered on the PCB.
Where 1K resistors are required as described in this document, the resistor leads should be formed as
shown below.
