Emerson E2 Manuel D’Utilisation

Board/Point #   The Board/Point Number will auto-

matically be defined if you are configuring the point 
from the Output Status screen, and indicates the 
physical address of the board.

Point Name   The Point Name is simply a name for 

the output point that may be used as a reference.

Assigning a descriptive name to a point makes set-
ting up outputs for applications much easier. For 
example, if you are setting up condenser fan #3 for 
condenser #2, you may choose to name it “CND #2 
FAN #3”. Then, when programming your Condenser 
Control application, you may easily define the fan 
output by tying it to CND #2 FAN #3. This keeps 
you from having to keep track of which contacts are 
tied to which point numbers.

You are required to enter a point name in the Point 
Name field. The default name is “:{BOARD 
NAME}:{UNIT NUMBER}:{BOARD NUM-
BER}:{POINT NUMBER}”.

Select Eng. Units   The Select Eng. Units field is 

where you may select how the ON and OFF states of 
this point are displayed and represented in the E2’s 
setup fields and status screens. By default, digital 
outputs have ON-OFF engineering units, meaning 
when the output is ON or OFF, the input will be rep-
resented as “ON” or “OFF” in the system software.

Engineering units are only a visual representation of 
the state of the output point (energized or de-ener-
gized). Therefore, it is not necessary to define engi-
neering units for digital inputs. However, selecting 
units that are appropriate to the output’s function 
(such as BYP or NO_BYP for inputs that initiate 
bypasses) will make the output’s state easier to read 
and understand.

To choose an engineering unit, press 

 (LOOK 

UP) to select.

Default Value   The value that the relay output 

should go to if the output is not associated to an 
application. The default value of the Default Value 
field is OFF. 

Physical On   Specifies whether the physical relay 

output should energize or de-energize its coil when 
the logical output is on.

Physical Off   Specifies whether the physical relay 

output should energize or de-energize its coil when 
the logical output is off.

Physical Null   Specifies whether the physical relay 

output should energize or de-energize its coil when 
there is no application associated with the output.

Minimum Physical On Time   Specifies the mini-

mum time the physical output must remain on 
regardless of the logical output state. 

Minimum Physical Off Time   Specifies the mini-

mum time the physical output must remain off 
regardless of the logical output state.

PRIORITY OVR   When an input is overridden to an 

output cell. If this input is not set to NONE, it will be 
used for the output value instead of the input value, 
but only for the override timeout period.

Priority Override Timeout   When an input goes 

on it will override to a value for the timeout period.

INPUT   This field links the output to an application. 

You do not need to enter anything in this field. You 
will be able to link applications to this point during 
the application setup process.

Open the Analog Output screen by selecting an Analog 

(A) output from the Output Status screen Figure 9-10 and 
pressing 

 (SETUP).

This is where output types, units, and default values 

are specified for analog output points.

In most cases, only the point name will need defining 

in this screen, unless you wish to change the 0-10V output 
range or configure a priority override.
