5 SETPOINTS
Some of the options supported by the 745 may be added while the relay is in the field. These include the Ana-
log I/O, Loss Of Life and Restricted Ground Fault options.
Should this be desired, contact the factory with the following information:
The 745 order code (found under A4 PRODUCT INFO/REVISION CODES/INSTALLED OPTIONS).
•
•
The 745 serial number (found under A4 PRODUCT INFO/REVISION CODES/SERIAL NUMBER).
•
The new option(s) that are to be added.
The factory will supply a passcode that may be used to add the new options to the 745. Before entering the
passcode and performing the upgrade, it is important to set the ENABLE setpoints correctly (see below). Any
options that are currently supported by the 745 as well as any options that are to be added should have the
corresponding ENABLE setpoint set to Yes . All others must be set to No .
For example, if the 745 currently supports only the Analog I/O option and the Loss Of Life option is to be
added, then the ENABLE ANALOG I/O? setpoint and the ENABLE LOSS OF LIFE? setpoint must be set to Yes . The
ENABLE RESTRICTED GROUND FAULT? setpoint must be set to No .
