1. UT 200611421(SN) encoder counter stopped working

On 1/9/2010

Shipped UT P/R board to ventor for repair.

On 1/14/2020

US Ultratek diagnostic results: 25 pin cable is damaged by rat. Two protection resistors for X encoder counter were burnt: one popped out completely and the other one is broken (no connection). The reason could be that the X encoder or wires were broken and output the high voltage. You may want to replace that encoder or wires.

On 1/15/2020

Fixed the problem by US Ultratek.

On 1/18/2020

The board is shipped back.

On 1/28/2020

The UT 200611421 was resembled and tested. Encoder counter is back to works.
