Replacing the Channel
Card
1. Once the switches are set, replace the channel card.
If you intend to connect pressure inputs or other input devices to the
Series 1, do not replace the cover because you will need to set
switches on the channel card for those inputs as well.
2. Slide the electronics unit into its enclosure and replace the screws.
Tighten the screws until they are snug. Do not over tighten. You
may now connect the recorder(s).
Connecting the
Recorders
Connect the outputs to the terminal block on the lower section of the
back panel labeled REC. See Figure 1-3 for terminal block location.
Make connections for recorders using Table 1-2.
