PHYSICAL DESCRIPTION
The main components of the SPS 4000 are de-
scribed in the following paragraphs and illus-
trated in Figure 1-3.
a. Manifold
The manifold provides a mounting platform
for the circuit board(s) and terminations and
contains the electrical feedthroughs. Also,
calibration gases are piped into and se-
quenced through solenoids mounted on the
manifold.
b. Calibration
Gas
Solenoids
The calibration gas solenoids sequence the
calibration gases. One solenoid controls
calibration gas 1 (high calibration gas), and
the other controls calibration gas 2 (low
calibration gas). The solenoids activate and
deactivate to allow the calibration gases to
flow between the sequencer and Oxymitter
4000.
c. Pressure
Switch
The pressure switch detects if the pressure
of a calibration gas is low, which can be
caused by an empty gas bottle, a discon-
nected gas line, etc. Calibration is prohib-
ited when calibration gas pressure is low.
d. Power Supply Board
This board converts the incoming line volt-
age from AC to DC for use by the solenoids,
terminations, and the programmable logic
device. The power supply board also has a
5 A, 250 V, slow blow fuse.
