PURPOSE AND SCOPE:
The purpose of the Galil RIO-47122
is to control and monitor the open and closed state of the APF spectrometer’s
entrance hatch. The Entrance hatch is located outside of the spectrograph
itself and the RIO is located inside the instrument (or "pod").
The limit board on the hatch has two input bits wired to the Galil
Rio
which
monitor
state of the Hatch. There is single output bit DO8 which controls the
state of the hatch itself. The input bit DI0 is the “Open Limit” and
DI1 is the “Closed Limit”. All signals are an "active
high".
The EL-3596, the Entrance Hatch Shutter Control Board, uses a
truth table, the level from the output bit from the
Galil, and the open or closed state of the APF spectrograph ADC’s
entrance hatch, to control a DC motor which open and closes the hatch.
A standard EL-1393 TRIPLE HALL EFFECT LIMIT BOARD provides the flagging
for the entrance hatch limits. |
