FREQUENCY
Frequency sets the trip unit’s internal
frequency to match the system
frequency.
Available settings are 50 and 60 hz.
MODBUS
Sets the communication parameters for the trip unit.
See SECTION 8: “Serial Communication” for details on how
to set up the Modbus communication.
DATE AND TIME
Sets the DATE and TIME parameters
The EntelliGuard Trip Unit has a Date and Time setting used
for Event Logs. The Date and Time can be set via the front
keypad, set-up software, or via Modbus communications.
The Modbus communication enables the Date and Time to
be set via a Clock Synchronization computer/server
(requires computer/server to communicate the Date and
Time in Modbus format).
Date and time values are pre-loaded for some point in the
future in registers 287 – 293. At the date and time entered
in those registers, command 103 is sent to the device,
which updates the device’s current date/time settings with
the new settings in the master clock.
The Date and Time need to be updated for Daylight savings
time, as it doesn’t have location based circuitry in the trip
unit. For the Event Log to record the Date and Time
Stamp, 24VDC is required on the trip unit.
Date:
• Y: Year, 3 Digits (2XXX), where XXX is the current year.
Example: 2010 would be Y: 010
• M: Month, 2 Digit Field, 1 = January, 2 = February, etc..
• D: Day, 2 Digit Field, 1 – 31
Time:
• H: Hours, 2 Digit Field, 0-24 Hours where ZERO (0) is
Midnight
• M: Minutes, 2 Digit Field, 0-60 Minutes
• S: Seconds, 2 Digit Field, 0-60 Seconds
LANGUAGE
Sets the display language
Available languages:
• English
• Spanish
• French

SCREEN TIMEOUT
Enables and disables the “return to
home screen” feature.
Available settings are “Yes” and “No.”
Should be set to YES if Modbus
communications are being used so
Modbus response time does not
increase.
When enabled, the trip unit will return
to the home menu after 10 minutes of
keypad inactivity.
