Hello,

I have a Linear Motor Amplifier made by ETEL. It is the DSA2 model.

Upon power up, the units red "error" LED immediately comes on. The LCD
display stays in "Self Test" mode and will not come out.

I cannot locate any documentation on the web, or on ETEL's website -
this unit appears to be a non supported older model of theirs.

If anyone has any ideas on this red "Error" LED, other things to try to
diagnose, or schematics/service manual for this unit, please let me
know.

Thank you,
WC
