OPERATION

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 4.11 - 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.
