6 DETAILED PARAMETER DESCRIPTION Factory<br />
ATTENTION!<br />
The connection of the motor to the Soft-Starter must be made<br />
carefully. Follow strictly the connection diagrams according<br />
to the winding types shown in Figure 3.5 and item 6.4.1.<br />
If reversal of motor direction of rotation is required, change<br />
the Soft-Starter connection to the network only.<br />
Ensure that the electronics is switched OFF while connections<br />
are changed each other.<br />
Do not start motor with wrong P28 content:<br />
OFF = standard connection<br />
on = within the motor delta connection<br />

6.4.2 - P43 - By-Pass<br />
relay<br />
<br />
<br />
This function, when enabled, permits activates full<br />
voltage indication by means of RL1 or RL2 (P51 or<br />
P52) in order to energise a by-pass contactor.<br />
The main function of the Soft-Starter By-Pass is<br />
to eliminate the losses in the form of heat generated<br />
by the Soft-Starter.<br />
NOTE!<br />
1) This function must always be programmed when a bypass<br />
contactor is used.<br />
2) To keep the protections relating to motor current<br />
reading, use external current transformers or the MAC-0x.<br />
See section 10.<br />
3) When P43 is set to "On", the parameters P74 and P76<br />
become inactive "OFF".<br />
