Emerson E2 Manuel D’Utilisation

seconds or greater, the SNTP will update the E2 time if 
enabled. When the E2 time is updated, an entry in Service 
Log is added.

If this field is set to No, the E2 clock will have to be set 

manually. If this field is set to Yes, SNTP support is used. 
Two SNTP servers are supported: Primary Time Server, 
and an optional Secondary Time Server.
Primary Time Server

The E2 will call up this primary server first to synchro-

nize the E2 time. If the primary server fails to respond, the 
secondary server is used.

Enter the IP address or name of the first server the E2 

should use to set the time (up to 40 characters). 
Secondary Time Server

The E2 will use this secondary server if no response is 

received from the primary server, or if the primary server 
is invalid.

If desired, enter the IP address or name of the second 

server the E2 should use to set the time (up to 40 charac-
ters). 
Date Format 

Dates may be presented and entered in either of two 

ways: month-day-year format, and day-month-year for-
mat. Choose the most appropriate date format by using the 
 (LOOK UP) tab.
Daylight Savings Dates

The Daylight Savings Dates type determines how the 

E2 will make date adjustments for daylight savings time. 
Use the 

 (LOOK UP) tab to cycle through the options 

in each of the fields. There are four options:

• STANDARD US DLT DATES - the E2 will use 

the standard United States’ method of  determining 
Daylight savings time dates. The Daylight savings 
time will start on the  Sunday of the second week of 
March ever y year, and will end on the Sunday of 
the first week of November (Note: these are the 
dates recently enacted by the U.S. Congress, which 
went into  effect in 2007).

• USER DEFINED DLT DATES - when this option 

is chosen, the user can specify start and end times 
for daylight savings, including month, week, and 
day settings.

• EUROPEAN UNION DLT DATES - the Euro-

pean Union Daylight rules are the same as the Stan-
dard US DLT Dates, with the exception that one 
hour must be added to the time at 1:00AM (GMT), 
during the last Sunday in March.

• DLT Not Used - the E2 does not make any adjust-

ments to Active Time for Daylight Savings Time.

This setting is only visible when Daylight Savings 

Dates is set to User Defined DLT Dates. If set to Yes, 
Daylight Savings Time uses GMT calculates the time to 
change from GMT and the current time zone setting. For 
example, if the start time is at 1:00 AM, and the time zone 
is +200 GMT, the time change will occur at 3:00 AM local 
time. Defaults to No.
Unit Location From

Sunrise and sunset times are calculated based on either 

zip code or latitude/longitude. If US Zip Code is chosen in 
the Unit Location From field, enter the zip code in which 
the controller is located. If outside the United States, 
choose Lat/Long and enter the latitude and longitude val-
ues in which the controller is located. Once a value has 
been chosen, the controller is able to calculate the sunrise 
and sunset times. The Sunset output will turn ON at sun-
set, and OFF at sunrise and can be connected to a lighting 
circuit.
Sundown

Sundown is an output that calculates when the sun sets 

based on latitude and longitude, and is ON when the sun 
sets. The user will select the Board/Controller, Point/
Application, and Input values from the 

 (LOOK UP) 

menu for each field. (When a Lighting Schedule is config-
ured to use Sundown information, the Lighting Schedule 
application automatically connects to the Sundown out-
put.)
