Installation PATH: SETPOINTS ! S1 745 SETUP !" INSTALLATION
To safeguard against the installation of a relay whose setpoints have not been
entered, the 745 will not allow signaling of any output relay, will have the In Service
LED off and the Self-Test Error LED on, until the 745 is set to “Programmed”. The
setpoint is defaulted to “Not Programmed” when the relay leaves the factory. The
SETPOINTS HAVE NOT BEEN PROGRAMMED self-test error message is displayed
automatically until the 745 is put into the programmed state:
Upgrade Options PATH: SETPOINTS ! S1 745 SETUP !" UPGRADE OPTIONS
Some options may be added while the relay is in the field. These include the Analog
Input/Output, Loss Of Life and Restricted Ground Fault options. Should this be
desired, contact the factory with the 745 order code (see
A4 PRODUCT INFO !"
REVISION CODES !" INSTALLED OPTIONS), the 745 serial number (see A4 PRODUCT INFO
!" REVISION CODES !" SERIAL NUMBER), and 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 descriptions 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 Input/Output 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”.
• ENABLE ANALOG I/O: Select “Yes” if the upgrade options set supports the
Analog I/O feature, otherwise select No. The default value for this setpoint
reflects the current state of the option.
• ENABLE LOSS OF LIFE: Select “Yes” if the upgrade options set supports the
Loss Of Life feature and select No otherwise. The default value for this setpoint
reflects the current state of the option.
• ENABLE RESTRICTED GROUND FAULT: Select “Yes” if the upgrade options
set supports the Restricted Ground Fault feature and select No otherwise. The
default value for this setpoint reflects the current state of the option.
• ENTER PASSCODE: Press ENTER to begin entering the factory-supplied upgrade
passcode. This setpoint has a textual format, thus it is edited in the same
manner as, for example, the setpoints under
S1 745 SETUP !" SCRATCHPAD.
• UPGRADE OPTIONS: When all of the above setpoints are properly
programmed, select Yes and press ENTER to prompt the 745 to upgrade its
options. A flash message appears indicating the results of the upgrade. A
successful upgrade may be verified by examining the installed options display
under
A4 PRODUCT INFO !" REVISION CODES !" INSTALLED OPTIONS.
