james2k2 Posted December 14, 2013 Share Posted December 14, 2013 Hi All, Firstly, thanks to dogcow who provided me the instructions on setting up my GS crane. Now the next issue to tackle is that it goes through periods where it flashes '4' on its display, which means the sensor is faulty or blocked. Has anybody else had this before? If so, how did you fix the issue? If not, does anybody know what sensor I require for it, I.e. is it an NPN N/O or PNP N/C etc.. Thanks all.
