DETAILED PARAMETER DESCRIPTION
6.4.5 -P50 - Function
of the Relay RL3
It enables the Relay RL3 to operate according to the
parameters set below:
1- The N.O. contact from RL3 is closed when the
SSW-03 Plus does not have a fault condition.
2- The N.O. contact from RL3 is closed when the
SSW-03 Plus have a fault condition.

6.4.6 - P51 - Function
of the relay RL1
It enables the Relay RL1 to operate according to the
parameters set below:
1 - Function “Operation”, the relay is switched ON
instantaneously with the order Switch ON of the Soft-
Starter, switching Off only when the Soft-Starter
receives an order of general switching Off, or by
ramp when the voltage reaches 30% of the rated voltage
(30% UN), as shown in Figure 6.7.
2 - Full voltage Function, the relay is only switched On
after Soft-Starter has reached 100% of UN, and
switched Off when the Soft-Starter receives a
command for general switching Off, or by ramp, as
shown in Figure 6.7.
NOTE!
The function of full voltage is used to activate the by-pass
contactor, the parameter P43 must be set at "On".
