When I was in television we were pestered by the "Barber Coleman" salesmen seeking sell an upgrade package for whatever standby powerplants were being used. System worked by a hall effect device running on the starter motor ring gear producing a square wave input for the controller. Output was a solenoid type device to the throttle. Response was tweakable fast/ poor waveform, slow but good waveform. They didn't get very far as the standby units were being upgraded/ replaced with higher capacity units with same controller. -- Regards, David ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
