Dynalco SW-100 Speed Switch - Manual (Page 6)

1.1 Place DIP switch 4 to the ON (up) position and DIP switches 5, 6, and 7 as shown.
1.2 Green input LED blinks the setting corresponding to the Operating Mode shown below, pauses
and repeats the value.
Setting Operating Mode
1 OVERSPEED trip, automatic Release upon return to normal
2 OVERSPEED latched trip, Release only after ALM Reset pulled to Common
3 UNDERSPEED trip, automatic Release upon return to normal
4 UNDERSPEED trip, start-up condition * ignored, automatic Release upon return to normal
5 UNDERSPEED latched trip, Release only after ALM Reset pulled to Common
6 UNDERSPEED latched trip, start-up condition * ignored, Release only after ALM Reset
pulled to Common
* Refers to initial application of power to the SW-100, not the input frequency.
X If existing operating mode setting is your desired requirement, this section is complete * .
Otherwise, continue with Step 1.3.
1.3 Press the push-button. The Green input LED blinks rapidly to indicate the Operating mode
setting is now accessed.
1.4 Turn the rotary switch to the selected numerical value for output desired (see the list in Step 1.2).
1.5 Press the push-button. The Green input LED blinks the value entered, pauses, and repeats the
new operation setting.
X If the new Operating mode setting is acceptable, this section is complete * .
X If the new Operating mode setting is not the desired setting, repeat Steps 1.3, 1.4, and 1.5.
X If Red output LED blinks, the rotary switch numerical value is invalid. Repeat Steps 1.4 and 1.5.
* 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.
2.1 Place DIP switch 4 to the ON position and DIP switches 5, 6, and 7 as shown.
2.2 Green input LED blinks the existing Trip Frequency setting as shown in the examples below. 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).
X If existing Trip Frequency setting is your desired requirement, this section is complete * .
Otherwise, continue with Step 2.3.
2.3 Apply the desired Trip Frequency to the signal input pin.
2.4 Press the push-button. The Green input LED blinks rapidly. The acquisition process takes two
seconds plus one period of the input signal.
X If the new Trip Frequency setting is valid, the Green input LED turns on solid. Continue to
Step 2.5.
X If Red relay LED blinks, the new Trip Frequency is invalid, outside the acceptable 0.1 Hz to 25
KHz range. Repeat Steps 2.3 and 2.4.
2.5 Press the push-button. The Green input LED blinks the new Trip Frequency setting. This section
is complete * .
X To verify Trip Frequency setting, see Step 2.2.
* 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.

RELAY INDICATION
Overspeed: The Relay LED (red) turns on to indicate the input signal
has exceeded the trip frequency.
Underspeed: The Relay LED (red) turns on to indicate the input
signal is below the trip frequency setting.
Invalid Entry during Set-up: The Input LED (green) and the Relay
LED (red) alternately blink until a valid entry is made.
