In order to provide
a
mJ.n1mwn cost system, the
PRIDE
Relay is available without user adjustments for
the nine functions listed above. The desired limits for these functions must be spe cified on the
purchase order. The set!Xlints for all but the Undervo1tage or OVervoltage function may
be
changed at
any time by addition of an optional M-0297/M-0397 Field Adjustment Unit which is easily installed by
the user. (The Undervo1tage or OVervoltage set!Xlints may
be
changed through a minor hardware modifica
tion) . The Field Adjustment Unit can also be used to monitor conditions such as line frequency and
timer progress, to enable certain fLmctions,
as
well
as
interrogating setpJints or trip targets.
When ordering the PRIDE Relay
ldth
the Field Adjustment Unit, the user must specify a set of fixed
backup settings that will
be
used if the M-0397 is later removed from the PRIDE.
If the optional M-0297/M-0397 Unit
� nQt
purchased and the user wishes to change PRIDE settings, the
old Memory Board model M-0298 containing the settings can be exchanged for a new one that can be
installed by the user. Alternatively, additional Memory Boards are available separately from the
factory.

and
will withstand 150% of nominal voltage for 5
sec. Operation from 250 V dc is posSible, but requires the external M-0319 Dropping Regulator

to provide 125 V dc nominal input voltage to the
PRIDE.
