ooo perhaps it has a thermistor in it, but this is not mentioned in the manual.

edit: it does have a themrostat shutdown mode but its not mentioned in manual it can be accessed externally.

ftransform:
I dont think its a temperature pin, it seems to  behave rather randomly. At first it does look like a temperature output, but it changes too quickly with programming voltage.
I left it connected to a load and it slowly rised to 11v, but then when I came back into the room (load was still running) it dropped to 9V. The room temperature did not really change much..

perhaps it cant be used in conjunction with voltage programming or there is some kind of fault in the circuit, because it does slowly rise when there is a load on it.

i might take this apart and trace it to something but I will wait for responses because that's alot of work.

yay its broke

30$ of repairs later.......

am I gonna have to buy a manual for this thing? :(

ftransform:
spare parts should be here soon bump

Using the sense + as the input and the neg as ground (for another supply) seemed to work for a while, but there was a mismatch (0.3 volts between control supply and output), but eventually this broke the controller IC.

rsaxvc:
Appologies for the necro-bump, but I've got the same wiring quesions for my pair of LK-351. However, I also found the instruction manual for Lambda LDS-X series, which use the same terminal names, and I'm hoping are wired similarly. Attached are the LDS series interconnection diagrams I found.
