TekLab TK4 Compressor Oil Level Control, Kevin's in Georgia??--- Episode 521TechLab TK4 Oil Level Controls: Dongles, Alarms, and Why “Limit Injections” Can Kill a RackBrett and Kevin swap war stories from a sweltering Georgia service call where Kevin quickly solves a persistent comm issue caused by a fallen rod rubbing through and shorting a comm wire, while also noticing a dangerously supported main water line. Back home, they dig into TechLab oil level controls (TK4/TK1), rant about hard-to-find manufacturer documentation, and walk through setting up the Bluetooth dongle/software to communicate, view status, and manually cycle the solenoid to watch oil-fill timing. They highlight how the “limit injections” setting can stop refilling during an alarm and shut down a rack, discuss injection/monitoring timing tradeoffs for low vs. medium temp systems, and note the pressure differential setting doesn’t appear to change timing automatically. They compare TechLab favorably to Kriwan, show teardown observations, and joke about laptops, metric screws, and oil-shower failures.
