After you make auxiliary input connections, you must set switch
block S1 on the Series 1 channel card(s) for the current or voltage
input. Use the following steps to make the proper switch settings:
1. Remove the screws on the front panel and slide the electronics unit
out of its enclosure.
2. Remove the channel card by sliding it straight up. Refer to Figure
1-13 for the location of the channel cards.

3. Locate switch block S1 (see Figure 1-11 for switch S1 location).
Switch block S1 has two switches, 1 for Auxiliary 1, and 2 for
Auxiliary 2.
4. Set the switches in one of two positions - ON for current or OFF
for voltage.
5. Check or reset switches for each channel where you are using an
auxiliary input.
1. Once the switches are set, replace the channel card.
If you intend to connect other type of input devices to the Series 1, do
not replace the cover because you will need to set switches on the
channel card(s) 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 have completed connecting the output device. Refer to Verifying
and Entering Setup Data in Chapter 2 of the Programming Manual to
properly set up the auxiliary input.
