text: <s>[INST] NEW TO CONTROLS PF 400 SIMPLE 2 SPEED HOOK UP I HAVE A PF 400 I AM TRYING TO HOOK UP TO AN EXHAUST HOOD WITH OUT PLC. ALL I NEED IS A SIMPLE 2 SPEED CONFIQURATION. I KNOW I CAN ADJUST IT ON THE FACE PANEL BUT I DO NOT WANT ANYBODY TO MESS WITH IT, TRYING TO MAKE IT FOOL PROOF TO A POINT:smileyhappy:. ANY HELP WOULD BE COOL. [/INST] DDP, an easy method, using two fixed speed, could be to use Preset Frequency, activated in this case with just one Digital input (terminal 05); terminal 06 isn't connected (that means logic 0) so you have the first speed if dig in 1 is open and the second speed if it is closed.The two speed are presetted in param A143, A144.Following some screenshots from User Manual in order to correctly configure this function. Hope this helps...:smileywink:- fuzzy logic \\n </s>
