5:3 Connection of communication devices (optional)
5:3.1 Fieldbus communication
The fieldbus communication plug must be connected to the communication interface on the front of the PST,
see Figure 26. Make sure that the plug is in correct position and tighten the screw with 0.8 Nm (7.1 lb in) and
additional 1/4 turn.
For programming and other information, see Chapter 7 “ Settings and configuration” and Chapter 8 “ Field-
bus communication (option)”.
5:3.2 External keypad
An external keypad for door mounting can be connected to the softstarter. A 3-meter cable including both the
serial communication and the power supply to the keypad makes the connection.
The external keypad can also be used for transferring parameters from one softstarter to another during
commissioning (temporarily handheld). Note that NEMA 4/4X cannot be achieved when the keypad is not
mounted.
When thee external keypad is used, both keypads will work in parallel but the softstarter keypad always has
the highest priority if the keys on both units are pressed simultaneously.
5:3.3 Transferring parameters
To transfer (copy) parameters from one softstarter to another, connect the keypad to the chosen softstarter and follow the
sequence below.
5:3.3.1 Uploading parameters
Enter the menu
Transfer par.
Select
To Keypad
and confirm by pressing

when the text

is displayed.
Transfer OK
will now be displayed
if the transmission was successful. Otherwise,
Transfer Not OK
will be displayed.
