4.9 RESET
4.10 DI2 DIGITAL
INPUT SETTING
A fault condition can be reset using the RESET key at the front of
the SSW-07 or through a push-button (0.5 seconds) at DI3 (digital
input for RESET). Another way to reset the SSW-07 is by switching
Off/On the electronic power supply (A1 and A2).
NOTE!
The SSW-07 also allows for the possibility of automatic RESET by
enabling this function through the DIP Switch (auto):
 Automatic RESET occurs after 15 minutes in the following
conditions:
-Overcurrent;
-Phase loss;
-Stall;
-Overcurrent before By-pass;
-Frequency out of range;
-Contact of the internal By-pass relay is open;
-Power control supply undervoltage;
-External fault.
 For incorrect phase sequence there is no automatic RESET.
 For electronic overload of the motor there is a specific algorithm
for the automatic RESET time.
In the factory default, the DI2 digital input has its function programmed
for the reset of faults. DI2 can also be programmed to work as a
three wire control.
The three wire control allows the Soft-Starter to be commanded
through two digital inputs, DI1 as an ON input and DI2 as an OFF
input. This allows for the direct placement of two push buttons.
Refer to item 3.3.2.
To change the DI2 digital input, follow the instructions below:
1. To enter in programming mode, maintain the reset key at the
front of the SSW-07 pressed for 5 seconds. Maintain the reset
key pressed during programming;
2. When in programming mode, two LEDs will turn on (overcurrent
and phase loss), indicating that DI2 is programmed for fault Reset.
When three LEDs turn on (overcurrent, phase loss and phase
sequence), it indicates that the DI2 is programmed for three wire
commands;
3. To change the programming to three wire commands, move the
overcurrent DIP Switch and return to the previous position. The
three LEDs will turn on, indicating that DI2 is programmed for
three wire commands;
4. To change the DI2 programming to fault Reset, move the Kick
Start DIP Switch and return to the previous position. Two LEDs
will turn on, indicating that the DI2 is programmed for fault Reset;
5. Programming is concluded when the reset key is released.
