Parameter: Unexpected Restart Period
•
Default Setting: 1 hour
Restarting of the device is blocked if the number of unexpected starts exceeds the Unexpected
Restart Count within the Unexpected Restart Period.
Unexpected starts are initiated by the relay watchdog.
The device will display an error message and enter locked-up mode. When locked-up, operation of all
LED’s and binary outputs, including Device Healthy, all pushbuttons and any data communications is
disabled. Once the relay has switched to the locked-up mode, it is non-recoverable at site and must be
returned for repair.
Parameter: Trip Alert
•
Default Setting: Enabled
When set to Enabled the fascia automatically displays the Fault Records screen when a binary
output configured as a trip contact operates (see Binary Outputs > Trip Config > Trip
Contacts).
When set to Disabled the Fault Records screen is not automatically displayed on the LCD after
operation of a trip contact. This setting is typically used during testing and commissioning to facilitate
repetitive testing i.e. there is no requirement to repeatedly reset the LCD screen.
Parameter: General Alarm Set
•
Default Setting: Enabled
When set to Enabled the fascia automatically displays the General Alarm screen when a binary
output configured as a General Alarm operates (see Binary Inputs > General Alarms).
When set to Disabled the General Alarm screen is not automatically displayed on the LCD after
operation of a General Alarm binary input. This setting is typically used during testing and commis-
sioning to facilitate repetitive testing i.e. there is no requirement to repeatedly reset the LCD screen.
Parameter: IEC 61850 Configured Alert
•
Default Setting: Disabled
This function provides indication that the IEC 61850 configuration has not been parameterized, it can be
used to operate a binary output.
Parameter: Relay Identifier
•
Default Setting: 7SR5
User defined text can be used to confirm the identify of the device e.g. when accessed remotely.
This user defined text is displayed on the top 2 lines of the LCD display home screen.
The Relay Identifier is used in communication with Reydisp to identify the relay.
Parameter: Circuit Identifier
•
Default Setting: <None>
User defined text can be used to identify the circuit monitored by the 7SR5 device.
