• System Events
–
Number of Events Currently Stored in Log – displays the number of events that can be displayed to the user. The
events are stored in rows from 1 to 200.
–
Operator Input – Select Event No. To Read – The operator inputs what event (row) that is desired to be displayed.
If the most current event is to be read, the operator would input a 1 in this field and then press the "Read Selected
Event" button. The event and time stamp would be displayed in the "Event Selected" field.
–
Read Selected Event History – stores the last 3 event rows that have been selected. The history is recorded in FIFO
(First in First out) memory.
–
The Events that can be read are as follow:
-
Ground Faults Cleared – "Phase-to-ground faults no longer detected. Any Undetected faults may still be
on system."
-
System Charging Current – "System charging current has been calculated. View Parameters screen for
calculation result."
-
Test Resistor Connected – "Test Resistor has been connected."
-
Voltage Within Limits – "Voltage across the NGR has returned to normal."
-
Current Within Limits – "Current through the NGR has returned to normal."
-
Pulse Start – "Pulsing of faulted system through NGR has started."
-
Pulse Stop – "Pulsing of faulted system through NGR has stopped.
-
Password Changed – "Password has been changed."
-
Password Disabled – "Password disabled. Protection removed from system. Unauthorized user access al-
lowed."
-
Password Enabled – "Password enabled. Protection returned to system. Unauthorized user access not

The Alarms that can be read are as follow:
-
Voltage Above Limit – "Warning!! Voltage across NGR has exceeded maximum alarm value."
-
Voltage Below Limit – "Warning!! Voltage across NGR is below the minimum alarm value."
-
Current Above Limit – "Warning!! Current through NGR has exceeded maximum alarm value."
-
Current Below Limit – "Warning!! Current through NGR is below the minimum alarm value."
-

-
Phase B Fault – "Warning!! A single-line-to-ground fault has occurred on Phase B."
-
Phase C Fault – "Warning!! A single-line-to-ground fault has occurred on Phase C."
-
NGR Failure – "Warning!! An open circuit has occurred in the NGR. An ungrounded system condition may
result."

9.7 Temperature Monitoring

The Temperature Monitoring screen allows the user to remotely monitor the temperature of optional embedded temperature
sensors. Typical monitoring applications are bus bar bolted connections and cable/lug connections.
