mvsgas Posted December 12, 2017 Author Share Posted December 12, 2017 additional info A1-A8VBB-NFM-000, page 2-10 to 2-11 paragraph 2.3.3.2 2.3.3.2 Manual Fuel Switch The MAN FUEL switch is located in the striped area of the throttle quadrant and is a three position switch spring loaded to center. The switch must be actuated until the MFS caution illuminates or extinguishes to achieve MFS selection or deselection as appropriate. Up to one second may be required. The switch energizes a solenoid which magnetically latches in theMFS or DECS position. Aminimum of 16 voltsis requiredtomovethe solenoid, however, switchingmay be achieved with as low as 5 volts available. The solenoid directs fuel pressure to the changeover valve to achieve the required change, which is signalled by the MFS caution. Therefore, if MFS is selected or deselected with the engine off, the full change over will not take place until the engine is starting and fuel pressure becomes available, the MFS caution will then signal the change. The ignitors and primer solenoid will still operate according to the selection of the MFS switch. The igniters are not rated for continuous operation; therefore, if operational conditions permit, the MAN FUEL switch should be placed to OFF before engine shutdown. DC power is required to switch from DECS to MFS when using the MAN FUEL switch. Inflight, once manual fuel has been selected, it should not normally be deselected. ON – Engine control transferred from DECS to MFS. (Center) – Neutral position. OFF – Engine control transferred from MFS to DECS Apparently, it is a 3 position switch, not two. To whom it may concern, I am an idiot, unfortunately for the world, I have a internet connection and a fondness for beer....apologies for that. Thank you for you patience.
