CHAPTER 4 - INSTALLATION INSTRUCTIONS
16.2 Individually Powered Control Cards
Note: In individually powered control systems a DC connection is still
required to the DC Input Card in order to provide power to the
Engineering Card.
Individually powered control cards may be required where the local or
other regulations dictate individual connections in order to achieve the
highest integrity for power distribution.
Individual powering of a single channel control card is easily achieved
as follows:
(1) On the Single Channel Control Card, remove the link LK1 from
position 1 - 2 and refit in position 2 - 3 as shown below:
The individual power supply to the control card must be fused
externally by a 1A fuse
Note: On older versions of the single channel control card the Link LK1
was not fitted. In this case the yellow disk fuse FS1 must be
physically removed from the card.
(2) Wire the +24V DC power supply to the respective field or Relay
Interface Card terminals 35 (+24V) and 36 (0V) as shown above.
