20 Settings Record
This 7UT51 (version 3) settings worksheet enables
easy recording of 7UT51 parameter settings when
configuring the relay. The settings are listed in
numerical sequence based on Address just as they
appear on the LCD. Where applicable, value ranges
are provided for easy reference. Only configurable
settings are listed.
Before configuring the device, copy this form and
enter the device identification number as well as the
date of configuration. Then simply mark an X beside
the desired options and enter numerical values in the
blank spaces provided. The factory defaults appear in
a column. Where different ranges and defaults apply
for the 1 amp and 5 amp nominal relays, the 1 amp
values are in parentheses below the 5 amp values.
After entering all data on this configuration form, take it
to the device and enter the information into the relay.
This form allows for the recording of all four setting
groups. Be sure to file a copy of this worksheet for
future reference.
