I have a Stannah 300 that is only moving a couple of mm at a time. There are six LED's on the PCB and no4 is flashing, plus No. 6 is on. Does any one know what these LED's are indicating.

hi clive...300sl....led 4 on the main pcb will pulse once per second indicating software operation this is normal....led 6 indicates active 5v supply....(it sounds like your main carriage batteries are discharging)
you need to test the 2 x 12v batteries between the seat plate and carriage,these batteries if good should show 24v+ combined,, if under 21v or less then they need to be replaced..also check the mains spur supply is switched on as this can get switched of by mistake causing carriage batteries to drain.....regards
