following Rolf's suggestion we test the HWWD units with +-24V instead of +-18V, we first reproduced the start up error on unit2 in the DTS with 18V. In five power up cycles the unit did not auto startup, the LED is red and the reset button needed to be pressed to continue the startup. We then powered with 24V and found the same results, five start, none auto started.
We then moved out 24V power supply to the CER and powered the unit attached to ITMY with 24V. Again we power cycled five times, once (20%) the system auto ran, four times (80%) it stuck at the red LED and needed a reset to continue.
Results indicate error is not fixed with increasing the power from 18V to 24V. The DTS unit is left off, the CER unit was returned to 18V.
