S 11.24
FREQUENCY TRIP
DELAY 1.0 SEC
The delay time before a trip is given can be selected here. Range is 1 - 127
sec. in steps of 0.5 sec.
S 11.25
FREQUENCY TRIP
RELAY AUX1
This message indicates which relay will be activated when the trip level is
exceeded.
S 11.26
MTM SCALING
FACTOR 655
This setpoint ranges from 1 to 655 and is used to set the full scale value for
the MTM analog outputs (KWatts and KVars). Full scale would then be as
follows:
100KW × scaling factor
30KVar × scaling factor
S 11.27
VOLTAGE REVERSAL
TRIP ENABLED
The 565/575 Relay incorporates the Voltage Reversal Trip feature. In order
to operate the feature successfully, the 565/575 must be communicating
with the MTM or MTM Plus, since the MTM/MTM Plus performs the
calculations to determine phase reversals. The 565/575 Relay provides
only Trip Relay Output and Programmable Trip Delay. The Phase Reversal
Trip of the 565/575 is independent of the Phase Reversal setpoint in the
MTM/MTM Plus. This means that whether the setpoint is ENABLED or
DISABLED in the MTM/MTM Plus, the 565/575 still polls for and receives
report on phase reversals.
S 11.28
VOLTAGE REVERSAL
DELAY 1.0 SEC
The Voltage Phase Reversal Delay is entered here in the range of 1 to 127
sec. in steps of 0.5 sec.
S 11.29
VOLTAGE REVERSAL
RELAY TRIP
This setpoint allows the selection of the relay that will be activated when a
voltage reversal is detected.
