Otherwise, skip to the next section of this document.
Procedure When Another Expansion Card is Preinstalled
1.
Shut off the power to the PF2100 system.
2.
Remove the 4 machine screws from the expansion card that is already installed in your PF2100 system. See Figure 3.
3.
Remove the 4 machine screws and 4 standoffs from the new 4-20mA card that you are about to install. See Figure 4.
4.
Attach the 4 standoffs to the expansion card that is already installed in your PF2100 system. Tighten to 4 in*lbs. Do not over tighten or the standoffs
may break. See Figure 5.
5.
Carefully install the new 4-20mA Input Card on top of the existing expansion card such that the long pinned header on the 4-20mA Input Card mates
with the socket on the old expansion card. Be careful not to bend any pins while doing this. Continue to apply pressure to the 4-20mA Input Card until
the header is fully inserted. See Figure 6.
6.
Finish attaching the new 4-20mA Input Card to the old expansion card using the 4 machine screws that were previously removed. Tighten to 4 in*lbs.
See Figure 6.
7.
You are done installing the card! You should have the following extra parts left over which you can either discard or keep for future use: 4 machine
screws and 4 hex nuts.
