Hello Dear all,

I have a problem in working with SITOP Power 40 ( input: AC 3phase, output: DC 24V, OrderNumber: 6EP1437-2BA10 ).

My problem:
When i'm connecting the input voltage to the SITOP module, i have the output. but when i'm resetting the SITOP module and set it again, i don't have the output any more.
The funny is here, when i'm handling some of elements ( transistors ) on the electronical board of the SITOP module, then the green LED that are located at inside of the output terminals, became ON, that indicates the output is connect.

My questions:
1) What's the problem?

2) How can i test the electronical board  exactly?

3) Where can i find the plans for electronical board of  SITOP Power 40 modules to exact test of the electronical board?

Please help me.

Best regards
Tekabi


 

 Dear Tekabi,

Please tell us first what do you meant by "resetting the SITOP module and set it again"

Hello,

Thanks for your reply.

I mean, when i disconnect the input voltage ( AC_3phase ) of the SITOP module and connect the input voltage again, i don't have any signals ( DC_24V ) in the output.

Thanks Thanks Thanks

Hello,

For mentioned Power supply "6EP1437-2BA10", please check all input wires that are well connected. 

Please check that your protection device feding the power supply is in a good condition and the three phase is well connected.

The mentioned power supply input is three phase input. In case of only two phase is connected, you will not get any output.

Hope this helps.

Hello Dear Ayman Elotaify,

Thanks for your reply.

I have checked all input wires and also protection device that feeding the power supply. There is no problem.

I think the problem is frome the electronic board. so i want to test individual elements. but i don't have the plans for the electronic board.

May you please tell me that where can i find the plans i need for this?

Best regards

 Hello,

Normally, Siemens do not pubish drawings for circuit diagrams of its products.

You can contact your local Siemens representative to investigate the problem.
