3.1 Place DIP switch 4 to the ON position and DIP switches 5, 6, and 7 as shown.
3.2 The Green input LED blinks the existing Trip Frequency setting, pauses and repeats. Six full
digits of numerical information blink with a 2 sec. pause between digits and a 4 sec. pause at
the end, before repeating. The first five digits are the existing Trip Frequency magnitude. The
sixth digit is the frequency resolution (the number of digits to the right of the decimal point).
If the existing Trip Frequency setting is your desired requirement, this section is complete

.
Otherwise, continue with Step 3.3.
3.3 Determine the Trip Frequency and record in the space provided below.

3.4 Press the push-button. The Green input LED blinks rapidly. Trip Frequency setting is now
accessed.
3.5 Turn the rotary switch to the first selected numerical value. Press the push-button. The Green
input LED continues to blink rapidly. First of six numerical digits is entered.
3.6 Turn the rotary switch to the second selected numerical value. Press the push-button. The
Green input LED continues to blink rapidly. Second of six numerical digits is entered.
3.7 Repeat Step 3.6 three more times then go to Step 3.8. This enters a total of five of the required
six numerical digits.
3.8 Turn the rotary switch to the selected numerical value for resolution requirement. Press the
push-button. The Green input LED blinks the new Trip Frequency setting (as described in Step
2.2), pauses, and repeats the value.
Ferrite Suppression Cores for signal and control cables:
If the new Trip Frequency setting is acceptable, this section is complete

.
If the new Trip Frequency setting is not the desired setting, repeat Steps 3.4, through 3.8.
If the Red relay LED blinks, the numerical value entered is invalid. Repeat Steps 3.3
through 3.8.

Section complete; place DIP switch 4 to the down position for normal operation, or change DIP
switches 5, 6, and 7 for the next Configuration Section.
4.1 Place DIP switch 4 to the ON position and DIP switches 5, 6, and 7 as shown.
4.2 The Green input LED blinks the existing Minimum Response Time setting (see following list),
pauses and repeats.

4.3 Press the push-button. The Green input LED blinks rapidly. Minimum Response Time setting
is now accessed.
4.4 Turn the rotary switch to the selected numerical value for Minimum Response Time desired
(see list in Step 4.2).
4.5 Press the push-button. The Green input LED blinks the value entered, pauses, and repeats the
new setting.

If the new Minimum Response Time setting is not the desired setting, repeat Steps 4.3, 4.4,
and 4.5.
If the Red relay LED blinks, the rotary switch numerical value is invalid. Repeat Steps 4.4
and 4.5.
