Sometimes (not all the time) after an exposure the red light is blinking. Here's the process:
set units of light on E1 preset
turn on vacuum
start the exposure and exit the room
when I return after the exposure is over the red light next to E1 (or E2 if I've used that as my preset) is blinking
Does this mean that my exposure is compromised?
Does anyone out there have a pdf of the FULL manual btw?
Have you stayed in the room (with UV-safe glasses, of course) to see if the exposure completes (counts down all the way), or if it aborts at some point in time?
I have a different NuArc, so I can't comment directly, but you could also check your line voltage during exposure. It could be dropping too far and causing a problem for the electronics.
Anyone know if the 26-1ks has a thermal cutoff?
Lastly, M&R Print, which owns the NuArc brand, services these machines. You should contact their service department. They should be able to help you.
