#54745, "RE: Vertical sliding Watertight Door system" In response to In response to 16 Tue Mar-07-17 11:39 PMby b-rad
If the magnetic solenoid was to merely lift the weighted bell crank in order to release the clutch and thus the pressure put on the friction disks, than how did it prevent the reopening of the doors, as they could not be reopened until after the bridge turned 'off' the electric charge? There was no brake system, as far as I'm aware of, connected to the solenoid. To the extent of my knowledge the solenoid did not have anything to do with the door itself, and only in the operation of releasing the clutch. Perhaps they would not have remained opened (aka they'd keep falling down) if lifted until the clutch was reengaged- which could only be done if the solenoid was turned off. Could this be what the instructions on the bridge next to the WTD controls have meant?
I edited this post, for after reading it awhile after posting, I did not think it was clear enough. Hope it is now.
