How to configure Multiple D7038, DS9484 NAC Power Supplies
When AC power is lost on all 6 - D7038's it causes NAC1 on the D7024 that is driving the inputs of the D7038's to go into trouble. What is causing this to happen?
The AC dipswitches 2 & 3 on the D7038's all had different settings. In order for the AC Delay feature to work, all the AC dipswitches 2 & 3 need to be set for the same value.
Note: In order for Dip Switch Changes to take effect the D7038 needs to be powered down completely for 4 minutes.
