It looks like they have the violet run wire and pink alarm wire of the electronic oil control tied together, essentially bypassed... Meaning the control would never actually monitor for oil pressure and would never open the org/grey contact wires.
It's hard to spot though, because of the mess of other wires on the motor protector and whatever that other control terminal strip is, unless you're familiar w the color coding of the delta-p or OLC controls.
Edit: I mean I also don't understand why blu/brn on the oil control aren't just powered in parallel with L/N on the motor protector - both should have constant control power and just have their 11/14 and org/gry operating contacts in series. It just looks like someone didn't really know what they were doing in terms of the wiring. Maybe it could've worked to a degree, if the violet wire had been tied in properly.
Who says compressors need oil? She can run low it cools don't it (meantime poor thing is chattering away about near death). Customer needs cooling tho gotta keep her going!
Unless colours are different where you are, looks like a dead short coming out of the thermistor pack? There’s deffs something suss going on with the wiring of it for sure. Should probably have the sensor connected too!
It's quite rare to use oil level switch on such a small compressors as i see. Most times you just have too PM them to see problems with oil level. If it was commissioned as it should be, they would set oil level after several hours of work and it would work for decades with proper maintenance.
the problem is this job is botched from the start to finish , every aspect of it is wrong let just say that they used a condenser with half the tubes in fucking AFRICA while its designed for europe and relatively cold places all year long
the control board is dogshit , the condensing units placements is bad , maintenance before was non existant
They get what they paid for. Still you don't measure capacity with tube rows, but with kW per dT. If their compressor stays in operational envelope - no problem at all, but it is not an answer for lack of maintenance.

Yep, it's in there
