[1] IN refers to connecting the two pins together. OUT refers to storing the programming plug by
placing it over a single pin, electrically floating.
[2]The positions of programming plugs E18, E21 and E22 must be the same.
[3] The positions of programming plugs E23 and E24 must be the same.
NOTE: Use figure 2.3 to locate the programming plugs.
2. Select source of +5V dc as the backplane or external supply. Record
your selection on Table 2.B by circling IN for backplane or OUT for
external.
Part B)
Select and record the analog board features on Table 2.C using the
following procedure.
Select the modules’ response to a hard fault or loss of +5V dc. Choose
maximum or minimum value for either output 1 or 2. Make these
selections regardless of how you set E2 in Table 2.B. If you selected hold
last value, you still must select maximum or minimum value for each
output. Outputs go to the selected value at module power-up (green LED
flashing) until the load/enter sequence is complete, or when powering
down +5V dc.
1. Choose minimum or maximum response of output 1 for hard fault or
power-down of +5V dc.
2. Choose minimum or maximum response of output 2 for hard fault or
power-down of +5V dc.
3. Choose analog input 1 as either voltage mode (+1 to 5V dc) or
current mode (+4 to +20mA).
4. Choose analog output 1 as voltage or current.
