PROGRAMMING
 The relay of the Operation Function closes its N.O. contact
(13-14/23) every time the SSW-07 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-07 receives the
disable command.
 The relay of the Full Voltage Function closes the N.O. contacts
(14/23-24) every time the SSW-07 applies 100 % of the voltage to
the driven motor. This contact opens when the SSW-07 receives
the disable command.

Figure 4.10 - Output relay operation
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-07 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-07
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.
