Relay Setup
Relay Setup settings are shown in Figure 61 and described in the following paragraphs.
Figure 61. Protection Screen, Relay Setup Tab
Relay #1, #2, #3, #4, #5, #6 – Contact Status. This setting configures the corresponding programmable
output as having normally open or normally closed contacts.
Relay #1, #2, #3, #4, #5, #6 – Contact Type. This setting selects one of three contact types: Momentary,
Maintained, or Latched. Selecting Momentary closes or opens the relay contacts for the duration
determined by the Momentary Time setting. Selecting Maintained closes or opens the relay contacts for
the duration of the condition triggering the relay’s change of state. Selecting Latched latches the relay
contacts open or closed until the relay is reset by the user.
Relay #1, #2, #3, #4, #5, #6 – Momentary Time. When Momentary is selected as the contact type, this
setting controls the duration that the contact is open/closed when the relay output is active. A time setting
of 0.1 to 5 seconds may be entered in 0.05 second increments.
PSS
The PSS screen consists of five tabs: Configure, Control, Parameters, Output Limiter, and Rate of
Change. Click the PSS button on the tool bar to view the PSS screen.
Configure
Configure tab settings consist of Setting Group Logic settings and Rate of Change settings. The Setting
Group Logic settings are shown in Figure 62 and described in the following paragraphs.
Power Level – Threshold. When the power level increases above this setting (and PSS Setting Group
Logic is enabled), the PSS gain settings will switch from the primary group to the secondary group. A per-
unit Threshold setting of 0 to 1.00 may be entered in increments of 0.01.
Power Level – Hysteresis. Following a transfer from the primary PSS gains settings to the secondary
group, this setting determines the level of (decreasing) power where a transfer will occur from the
secondary group to the primary group. A per-unit Hysteresis setting of 0 to 1.00 may be entered in
increments of 0.01.
