GFI TRIP ALARM must be enabled in order to adjust the G.F. TRIP CURRENT level.
CAUTION:
In order to implement a ground fault trip function, ALL NON-GROUNDED power conductors
must be opened upon detection of a ground fault condition.
IMPORTANT: National Electrical Codes may require that all legs of non-neutral based power
sources be opened upon detection of a Ground Fault. Multi-pole switch configurations
should be used on non-neutral based power systems. Check the requirements with your local
Electrical Authority.
5.5.8 LOW VOLTAGE ALARM
Purpose: Alarms voltage levels that are lower than a preset limit for the application.
Alarm Mask: ENABLE or DISABLE
Range: 10 to 330 Volts
Procedure: Adjust the LOW VOLTAGE ALARM level to the desired value. Note that the LOW
VOLTAGE ALARM must be enabled in order to adjust the LOW VOLTAGE ALARM level.
IMPORTANT: It is recommended that the LOW VOLTAGE ALARM always be enabled.
5.5.9 LOW VOLTAGE ALARM FILTER TIME SETTING
Purpose: The LOW VOLTAGE ALARM FILTER will prevent LOW VOLTAGE ALARMS from being
indicated until a low voltage condition has existed for the duration of the LOW VOLTAGE
ALARM FILTER time.
Range: 0 to 12 seconds
Procedure: Adjust the LOW VOLTAGE ALARM FILTER time to the desired value. Note that the
LOW VOLTAGE ALARM must be enabled in order to adjust the LOW VOLTAGE ALARM FILTER
time.
IMPORTANT:
• If an alarm condition appears and then disappears before the alarm filter time has expired,
the filter timer is reset and the alarm condition must exist again for the entire alarm filter
time before the corresponding alarm will be indicated.
• If the user resets an alarm while the alarm condition is still exists, then the alarm will not be
indicated again until the entire alarm filter time has expired.
5.5.10 HIGH VOLTAGE ALARM
Purpose: Alarms voltage levels that are higher than a preset limit for the application. Serves as
a monitor of the voltage used to power the tracing circuit.
Alarm Mask: ENABLE or DISABLE
Range: 10 to 330 Volts
Procedure: Adjust the HIGH VOLTAGE ALARM level to the desired value. Note that the HIGH
VOLTAGE ALARM must be enabled in order to adjust the HIGH VOLTAGE ALARM level.
5.5.11 HIGH VOLTAGE ALARM FILTER TIME SETTING
Purpose: The HIGH VOLTAGE ALARM FILTER will prevent HIGH VOLTAGE ALARMS from being
indicated until a high voltage condition has existed for the duration of the HIGH VOLTAGE
ALARM FILTER time.
Range: 0 to 12 seconds
Procedure: Adjust the HIGH VOLTAGE ALARM FILTER time to the desired value. Note that the HIGH
VOLTAGE ALARM must be enabled in order to adjust the HIGH VOLTAGE ALARM FILTER time.
IMPORTANT:
• If an alarm condition appears and then disappears before the alarm filter time has expired,
the filter timer is reset and the alarm condition must exist again for the entire alarm filter
time before the corresponding alarm will be indicated.
• If the user resets an alarm while the alarm condition is still exists, then the alarm will not be
indicated again until the entire alarm filter time has expired.
