UPBv2: Question about displaying a red arrow

[Ruediger]

Hello Evans,

i get a strange indication in the software and I am not sure what it means. The power port is switched off, but I get a red error. If I switch it on, everything is fine.
What does it mean?

A shortwire / overcurrent detected and controller disabled the port. Which device do you have there? (what is the delta-T?)

[Ruediger]

This is a Planewave Temperature and Focuser Controller together with the Delta-T Unit controlling temperature and fans if the CDK. It is switched off and does not pull any current. This symbol is shown all the time, when the port is witched off, when turn on everything is fine.

Yes, I have similar reports about this Planeware unit.
Probably a large capacitor inside Planewave's unit draws lots of current on startup and triggers the UPBv2 current protection.
You can ignore it for now

Thanks Evans,
The symbol only appears when it is switch of. As soon As I plug it in, but do not turn the port on.
