Output Relay Operation; Relay Output Rl1 Programming - WEG SSW-08 Manual Del Usuario

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.

4.11 OUTPUT RELAY OPERATION

The relay of the Operation Function closes its N.O. contact (13-14/23) every time the SSW-08
„
receives the enable command. This contact is only opened at the end of the deceleration
ramp (when it is set via trimpot) or when the SSW-08 receives the disable command.
The relay of the Full Voltage Function closes the N.O. contacts (14/23-24) every time the SSW-08
„
applies 100 % of the voltage to the driven motor. This contact opens when the SSW-08 receives
the disable command.

4.12 RELAY OUTPUT RL1 PROGRAMMING

In the factory default programming, the relay output RL1 has its function programmed for
"Operation". RL1 (13/14) can be also be programmed for the "No Fault" function. This function
allows the installation of a circuit breaker with an undervoltage release at the SSW-08 input. Refer
to figure 3.3.2. In order to change the relay output RL1 programming follow these instructions:
1. To enter in programming mode keep the reset key, at the SSW-08 front cover, pressed during
5 seconds, keeping it also pressed throughout the programming;
2. When in the programming mode two LEDs turn on (Overcurrent and Phase Loss), indicating
that DI2 is programmed for Error Reset. If three LEDs turn on (Overcurrent, Phase Loss and
Phase Sequence), it indicates that DI2 is programmed for three-wire command. If the Overload
LED turns on, then the RL1 function is "No Fault", otherwise the function is "Operation";
3. To modify the RL1 function change the Overload DIP Switch and put it back in the previous
position. The Overload LED will indicate the new programmed function:
- Overload LED off: Operation function;
- Overload LED on: No Fault function.
