Procedure When No Expansion Card is Preinstalled
1.
Shut off the power to the PF2100 system.
2.
Remove the 4 screws that hold the terminal card in place in the product enclosure. Do not lose these screws as you will need them later. See Figure 7.
3.
Carefully install the 4-20mA Input Card onto the Terminal Card such that the long-pinned header on the 4-20mA Input Card mates with the socket P1 on
the Terminal Card. Be careful not to bend any pins while doing this. Continue to apply pressure to the 4-20mA Input Card until the 4 standoffs fit into
the holes in the PCBA. See Figure 8.
4.
On the back side of the Terminal Card, install 4 hex nuts onto the standoffs to hold the 4-20mA Input Card in place. Tighten to 4 in*lbs. Do not over
tighten or the standoffs may break. See Figure 8.
5.
Place the terminal card back into the product enclosure and fasten it using the 4 screws removed previously. Tighten to between 12 and 26 in*lbs taking
care to not leave screws loose enough that the terminal card rattles around and not too tight that the enclosure holes begin to strip out. See Figure 7.
6.
You are done installing the card! There should not be any extra parts left over. If there are, double check if you have missed a step.
