Close bypass PSTX470...PSTX1250
The built-in bypass contactor in PSTX470..1250 can be
controlled externally for an direct on line (across the line)
start. The built-in bypass contactor is closed by applying
voltage (100VAC/DC – 250VAC/DC) to terminal 2 and 3.

Modbus RTU
Connect digital ground from PLC to the PSTX ground,
terminal 19, 22 or 30.
Terminal 23 to 29 is non-isolated to GND. Terminal 30
is the same as terminal 19 and terminal 22. If voltage is
applied to any terminal 23-29 it may break depending on
the amplitude of the voltage.
Terminal 23 and 24 will break down if voltage are higher
than ±5,5V (relative ground) and have a current more than
150mA. If using different grounds between master and
PSTX make sure that they are totally isolated grounds and
that the master has isolated power. The master must not
have any offset to the PSTX ground.

PTC/PT100 input
If the motor has PTC or PT100 elements, connect the
cables to terminals 25, 26 and 27.
See
chapter
7.14 Inputs/outputs
for programming.
3-wire measurement for PT100
To reduce the influence of the wire resistance, you can
use a 3-wire connection. This creates 2 measuring
circuits. One circuit is used for reference. This way, the
tripping device can calculate the wire resistance. See
Figure 5.22.
