S-SLT CON Speedmaster main motor

Excuse me everyone please help me, i have problem. My speedmaster read input voltage 3 phase randomly although the input voltage 3 phase is stable in 389 Vac.
Thank you in advance.

 

Hi sir;
Would you please explain, if the Input Voltage as you say is stable in 389Va??????

2) You machine input voltage is 400Vac?

3) What model from Speedmaster is????

4) However if the voltage 3 phase is randomly, please measure the Input in the main transformer, and TIGHT VERY WELL for looses wires, of INPUT ; FUSES +C. BREAKER , until the main transformer, look very well the Ground, and Neutral, look, for Oxide in terminals + Open Wires!!!.

5) Do measure of continuity in from the input until the Main transformer, for to see , if there any OPEN wires, or Ground with the chassis of the machine.

 

1. We use 380Vac for input machines.
3. CD102
I was already measure the input voltage, form input until the main transformer. N i got the result 389 Vac, but the value voltage in display ZID show randomly voltage.
Thank you sir for your suggestion.

 

what is the problem with the machine?

 

Ok,

1)Must measure output of secondary inain transformer, and see if there in tolerance in 10% up or down.

2) if is ok, measure Regulated Power Supply in tolerance from ,,0.7% up or down.

If there are Not in tolerance , you must Repair or replace board.

Otherwise you must have randomly voltage in ZID, as you indicate.

Blessings..

 

Ok, thank you for the input sir...
GBU...

 

My machine read input voltage randomly

 

Sir you are NOT dure, what problem do You have.

In the beginning you said the input was stable, 389 Vac.

After you told us, the ZID voltage I Randomly.

If the input is ok, I mean that you does Not measure Regulated power Supply!!!!.

Please do, that I can tell you, before.

Blessings

 

Please give me init test of slt-con to see what happends .
Tell me please is the machine running or not ??

 

Make sure that power in the transformer is good and check board if there are some leaked components

 

Please proceed with the Steps before.

Otherwise, you Will waste time and money.

Blessings

 

Good evening please, I would like to know what is the problem with the machine?
