3.2.3 Connecting Start and Stop
terminals to push buttons and PLC
Internal control voltage - Push buttons
The PSTX Softstarter has a built-in holding circuit and
does not require sustained signals on start input. Use
internal control supply voltage from terminals 20 or 21.
Connect start and stop terminals using conventional
circuit with push buttons. See Figure 6 and Figure 7.
Connect the white start push button as START and the
black stop push button as STOP in Figure 7.

External control voltage - PLC
The softstarter can, if required, also be controlled with an
external 24 V DC source from a PLC or similar.
Connect the cables according to Figure 8 depending on
which type of control method is used.
WARNING
Terminal 13, 14 ,15, 16 and 17 should be
connected using 24V DC only. Other voltages
may damage the softstarter and the warranty may
no longer be valid.
