Emerson E2 Manuel D’Utilisation

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.

To configure a point, go to the Input Definitions/Status 

screen by pressing Alt + I or:

1.

The Input Status screen opens:

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.

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 numbered input terminal.

4.

Place 250

 resistor across odd 

and even numbered input termi-
nals.

1.

If the input board is an 8IO or a 16AI version 
E.02 or greater, connect the two KWh terminals 
to 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.
