Hi guys,
We have a Lotem 800V, 48 diodes, app ver. 3.20.01
Following startup, the machine arrives at READY state.
After a while we get "ATTENTION" errors:
"Left Tec Card doesn't respond (Opcode 23)."
"The operation "Put" on left Tec Card failed."
If we try to perform Laser Diode Calibration or try to Expose, we get an additional error:
"DDB Card" doesn't respond (Opcode 80)."
"The operation "Put" on DDB Card failed."
My ex-Scitex technician tried to isolate the source by replacing (one at a time) TEC, DDB and NUC boards TWICE.
Going further, we checked continuity on the 50 pin cable connecting the L-Box to the E-Box (DDB to NUC), still getting the same errors.
We are now discussing ways to proceed.
Since we noticed the LEDs on the 3 Power Supplies in the L-Box didn't light up, we wonder if this may indicate a source to the problem.
We intend to find if the PS's get any AC power and later possibly replace the PS's.
Does anyone know which of the 3 PS's (+5V, -5V or +/-12V) should we try to replace first?
Any other possible source to this problem?
Any comment welcome.
TIA
