Electronic Description of Stage:
Controller is integral with PXL TV control box. #4IES214 as of September
1999. Coil resistance is 8.5 ohms. 24 volts to open and 3 volts
to hold. We add a reed switch and small magnet on one of the internal
blades for sensing open/closed. This is undocumented. The factory
limit switch for this function has a spring which is so strong it prevents
the shutter from opening on cold nights. Old part number: #04IES004
- turns out to be 12 volt shutter.
