fail safe question

[flyinryanp]

when the fail safe is activated for the manual boost controller should it stay engaged until the failsafe is shut off or does it energize the fail safe then turn back on in 3 to 5 seconds. im trying to use the maual boost controller wires to activate a relay that opens a large solenoid to vent boost. it initally activates opening the valve but then almost instantly shuts off and the valve closes.
