9.1.3 Input Setup in E2
At this point in the setup process, you should have all
sensors, transducers, and other input devices wired to
points on MultiFlexes, 16AIs, and all output devices con-
nected to 8ROs, 8DOs, or 4AOs outputs. Once the physi-
cal wiring is complete, you will need to tell E2 the types of
sensors
or devices that are connected to each I/O point.
This is achieved in the Input and Output Definitions
screens.
9.1.3.1 Configuring a Point from the
Input Definitions/Status Screen
To configure a point, go to the Input Definitions/Status
screen by pressing Alt + I or:
1. Press
to open the Main Menu
2. Press
(System Configuration)
3. Press
(Input Definitions)
The Input Status screen opens:
Figure 9-4 - Input Status Screen
Use the up and down arrow keys to move the cursor to
the point you wish to set up, and press (SETUP).
A pop-up menu such as the one shown in Figure 9-5
will prompt you to specify the point as analog or digital.
Press
if the input is analog, press if the input is dig-

4-20 mA output to input board
1. Wire positive transducer terminal
to positive 24VDC supply.
2. Wire negative transducer termi-
nal to odd numbered input termi-
nal.
3. Wire negative 24VDC supply to
even n
umbered input terminal.
4. Place 250 r
esistor across odd
and even numbered input termi-
nals.
Pulse Accumulator output to input board
1. If the input board is an 8IO or a 16AI version
E.02 or greater, connect the two KWh terminals
t
o the input point (polarity insensitive)
2. If the input board is a 16AI version less than
E
.02, connect the KWh terminals to board point
1. Set input switch #1 DOWN, and set input
switch #8 UP.
3. If the input board is a 16AIe, connect the two
KWh
terminals to input # 1, 2, 3, or 4 ONLY.
