5.5 Group Change Control Statement
The F-PRO 116 relay has two setting groups (SG1 to SG2). The user can change all relay setting
parameters except the physical connections such as inputs, in each setting group. Setting group
changes can also be performed by using any one of the four available Digital Inputs per setting
group or through relay display interface. The Group change inputs are similar to the LED and
output. The processing for activating the setting group is half a second. During the transition of
one setting group to another setting group, the previous setting group will still be operational.
Active Setting Group
The relay uses Setting Group 1 as the factory default setting group and retains the current active
setting group in memory. This allows the relay to use the last active setting group prior to
interruption of relay power as the default setting group following power up.
Group Change through LCD
In this screen, hit Enter and choose the desired setting group number using Up and Down keys,
and then click Enter.
The user can change the active setting group while loading settings from Offliner using
HyperTerminal. The same setting group may be used or the user may switch to a different setting
group.
Manual Settings Change
When the user initiates a manual setting group change, the change does not disrupt the relay
protection functions. The relay logs an acceptance of the change request and puts the new setting
file in service. When the new setting file is queued, the relay loads the new setting configuration
for protection functions to the protection processor. The relay loads the new name definitions
for the supplementary settings (including ProLogic names, and front panel target LED activation
rules) to the interface controller. When the setting load is completed, an event is logged to
show the completion of the request. There is a delay (approximately five seconds) between the
load request and the completion of the request where the new supplementary settings may be
temporarily applied to the previous setting file.
The protection processor does not have any interruption in service during a setting
group change.
