3.1.15. Configuring the Contact Filter Settings
The contact filter setting is applicable only for timing circuit breakers with insertion resistors.
Although the CT-7000 S2 automatically detects the contact time using its own algorithm, it also
allows the user to enter a custom filter value. The value can be between 1 and 300. A filter
setting of 1 allows the CT-7000 S2 to pick up the first contact transition time after the resistor
contact activity is detected. A filter setting of 300 allows the CT-7000 S2 to pick up the last
contact transition time after the resistor contact activity is detected. Use the steps below to set
the contact filter value:
a. Start from the “START-UP” menu:
Press the [4] key (DIAGNOSTICS).
b. The following screen will be displayed:
Press the [4] key (NEXT PAGE).
c. The following screen will be displayed:
Press the [3] key (CONTACT FILTER).
d. The following screen will be displayed:
Type the new filter value using the numeric keypad and then press the
[ENTER]
key.
The contact filter value will be set and you will be returned to the “START-UP” menu.
NOTE
The filter value will be reset to the automatic setting when the unit’s power is
cycled.
