S286 Troubleshooting Guide

The Fozmula S286 Oil Level Switch is an an active device that is designed to produce an alarm signal if the oil-based fluids fall or rise to an unacceptable level. The S286 also comes with a featured ’10 Second Delay’ option, limiting the possibility of false alarms.

The S286 features a programmable microprocessor  and can offer either one or two output pins that can sink to ground, supply a source voltage or both. With its tiny spatial footprint and limited tank intrusions translates to a reduced damage risk, the S286 is optimised for functioning in difficult environments and providing accurate responses.
