Cant start hydraulic,red light is on, on central lubrication unit.
When press manual process(black buton), wont start pump, red light stay on, and no power on terminal M
Oil level WS sensor is normal open(close when oil level drop) testing its ok
Presure level DS sensor normal open(close when presure up) cant testing, but if there is error pump shod start for one minut.
Power suply on L1 its ok(red light is on)
Some idea ?
