Drum don't stop on a Creo Lotem 800V2

[Duncan Hyde]

Same issue the diagnostics did not pick it up either i know it sounds crazy but in the long run the technicians got fed-up so they brought both boards in the E Box because along with incorrect voltage to the motor came up at times, it seem like one sends signals to the other and then did a process of elimination and found that it was the MCF board but, at that point running the machine with Drum issues like that could of damaged either board so we ended up keeping both new boards to make sure one does not keep fry the other vice versa $$$$$ change but had no problems since and that was two years ago.

For the UPS you put it right after the breaker but before the power box and hardwire the plug from the lotem tothe UPS. We use an APC SMART- UPS 75000 if you want pictures i can send you show the wiring

Hope this helps at least you have an idea of what kind of problem you could be having took us a while to figure out because it would not always occur noe would the lotem diag tool pick it up

Yes, but if i shut off the power of the ctp, the e-box will remain powered because the ups thinks that it have no power. So how can i shutdownthe CTP then ? By turning off the UPS ? Do i need a ups for 220V ?

None of the Creo techs ever solved a single problem on our equipment by using their diagnostics. Every single hardware problem was quickly and easily diagnosed by the symptoms by a field engineer. Creo never noticed this maybe Kodak will.

Careful Duncan, the Lotem 800 is a three Phase machine and so Alex can't use the same ups you use on the L400.

um having the same problems guys .. do any one can advice me wt do now ???

 

[outforkill]

i did find the MCF board
but
1- i cant fine 5v TP
secondly ..
i found three switches ( actually tiny switches ) on the(right - middle - left )

which one i have to change to get the right reading by Voltmeter

please any help guys

 

[PACH]

Do nut touch or change any of the switches. Take a torch and look down on the board and you will see the 5v and the GND TPs.

please man ... be accurate about wt u mean by the BOARD ... which one with the these pins and the switch .... if possible to send a pic

thanks in advance man for helping me here

Patch is clear in his mail look at the board u can see 5v and gnd means ground small text less than 5 points on board..; if u have spare MCF Board its very easy to test ...

thanks kala for your help

let me tell wt on the MCF board .. from right to left [ AGND1 - YCC1 --- GND1 ---------------ANA1-ANA2- AGND2 ]

thats for the MCF

wt about the switch .. i cant find any switches on the MCF board neither on the power supply but the three little ones i mentioned before :S

any comment !!!!

 

[PACH]

Use these to measure your +5.1V ------YCC1 --- GND1

thankx PACH for that ... i will do it tonight .. but for the switch to adjast the value 5.1 where is it exactly ???

it would be nice if u send me a picture :?!

thanks in advance

The potentiometer that you have to adjust is in the Power Supply Unit at the bottom of the E-Box (where all the Printed Circuit Boards) are. You can see and access this through the Trapezoidal lower cover near the feet. Get a torch ; go to the back of the Lotem ( Left Hand Side) looking from the back; get down on your knees and look through the small holes in the cover and you should see the Potentiometer. You will need a long thin screwdriver to do the adjustment.

Hello I bought a A Lotem 800 V, it was working in the printshop and now its in my house and the machine is showing the message: Phase R fail , Phase T fail and Phase S fail. What could be the solution ?

And if the card is broken which is responisble for the power supply where i can get a new one and what would be the price.

Tanks for you help!

Did you connect the Lotem to the 3 phase step down Transformer? You should measure about 208v phase to phase and 120v phase to earth. These are the 3phase voltages that supply the Lotem. Watch what you are doing when measuring the voltages.!!!!!!!!!!!!!
