1. ESD Warning
Please note!
The life span of electronics can be affected by damage caused by
electrostatic discharge. This can happen if a charged tool or person
touches a component. Therefore it is very important that all tools and
personnel are discharged by touching an earthed point before the printed
circuit board or any of the components are touched. It is equally important
to discharge the package with the new component before opening it.
A person walking on a carpet can be charged with up to fifteen
thousand volt (15000V). Compare this with the fact that some sensitive
components can be destroyed when discharged on a much lower level
(about 100V). We kindly ask you to pay notice to this, as this is a vital
point in order to ensure the life span of the product.
2. Tools
Torx T15 for removing the Cover from PST30 … PST72
Torx T20 for removing the Printed Circuit Board.
for removing the Cover from PST85…PST300 and PSTB370…PSTB1050
3. PCB information
For upgrade to Torque Control both LV board and HV board needs to be upgrade to following
version:
LV board 1SFB636068D1011
HV board 1SFB636068D1013

4. Step by step
1. Before disconnecting the cables mark them.
2. Disconnect the cables from terminals 1L1,
3L2, and 5L3 (main voltage).
3. Disconnect all cables from the terminals 1 to
20, external keypad, PTC sensor and the
Fieldbus plug.
4. Remove the front cover (four screws).
5. Discharge the tools and yourself by touching
earth (if you are not earthed).
6. Disconnect the cables on the HV-Board from
the thyristors and fans. Mark the cables from
the thyristors with L1, L2 and L3.
7. Remove the five screws.
8. Remove the old HV-Board. Don’t lose the
connector between HV-Board and LV-
Board.
9. Disconnect the cables on the LV-Board from
the thermal switch and current transformers.
Mark the cables from the current transformers
with CT1, CT2 and CT3.
10. Remove the six screws.

11. Remove the old LV-Board and disconnect the
cables from the Display and the Keypad.
12. On PSTB unit remove the cables from the
built in by-pass contactor after marking them.
13. Mount the cables from the Display and the
Keypad on the new LV-Board.
On PSTB units, reconnect the cables from
the built in by-pass contactor. Be careful
how you connect the Red (L) and Brown
(N) cable.
14. Mount the new LV-Board with the six
screws.
15. Mount the connector. Be careful to avoid
damage on the pins.

16. Mount the new HV-Board with the five
screws.
17. Mount the cables from the thermal switch
and current transformers on the LV-Board.
Be careful how you connect the cables
from the current transformers (correct
phase sequence).
18. Mount the cables from the thyristors and
fans on the HV-Board. Be careful how you
connect the cables from the thyristors.

19. For upgrade to Torque Control it is
important to check the connection on the
current transformer (see fig below).
20. If the two cables on each current
transformer are black use a multimeter to
detect the right connection. The resistance
of the current transformer are between
0,2-6 ohm.
21. Change the position of the cables on the
current transformers to obtain correct
position if necessary.

22. Mount the front cover (four screws).
23. Connect all cables to terminal 1 to 20,
external keypad, PTC sensor, Fieldbusplug
and the cables to 1L1, 3L2 and 5L3.

5. Configuration of the LV board
If only the HV board is changed, the softstarter is ready to start. If the LV board is changed, a
programming of this must be done before the softstarter can be taken in operation. Every softstarter
size has its own parameter values for the LV board according to table 1 or 2 that must be used.
Follow the step by step instruction below to do this set-up.
1. Switch on the power supply (terminal 1 and 2).
2. Enter the menu Service settings using following path:
Menu / SETTINGS / Service Settings / New PCB and press Select
3. Press Yes on the question “Are you sure?”
4. Set the required display language. Press Store to save the value and press Next to continue. If
wrong language was selected press Back for previous level. These commands are valid for
the whole set-up.
5. Set the parameter CT Ratio Ir. (table 1 or 2)
6. Set the parameter Int ByPass. (table 1 or 2)
7. Set the parameter ByPass AC3. (table 1 or 2)
8. Set the 4 parameters SOP1 - SOP4. (table 1 or 2)
9. Set the parameter PST(B). (table 1 or 2)
10. After pressing Next when the parameter PST(B) is set, the programming is complete.
11. Before taking the softstarter in operation, don’t forget to set the rated motor current and
activate the required protections, warnings, input / outputs etc.
12. For set-up of Torque Control during start and stop see separate manual sheet or update
manual.
