1-4. SPS 4000 (OPTIONAL).

The SPS 4000 Single Probe

Autocalibration Sequencer provides the capability of

performing automatic, timed or on demand, calibra-

tions of a single Oxymitter 4000 without sending a

technician to the installation site.

a. Mounting.

The SPS 4000 can be mounted either

directly to an Oxymitter 4000 or at a remote loca-

tion if space is limited. In addition, the integrally

mounted SPS 4000 can be configured for a hori-

zontally or vertically mounted Oxymitter 4000

(Figure 2-2). The information in this instruction

bulletin will cover the integrally mounted units

only. For information on remote mounted units, re-

fer to the SPS 4000 Single Probe Autocalibration

Sequencer Instruction Bulletin.

b. Components (Figure 1-5).

The SPS 4000 con-

sists of a manifold and a calibration gas flowme-

ter. The manifold provides electrical

feedthroughs and calibration gas ports to route

power and signal connections and calibration

gases to and from the sequencer. In addition, the

manifold houses two calibration gas solenoids

that sequence the gases to the Oxymitter 4000, a

pressure switch that detects low calibration gas

pressure, and two PC boards. A terminal strip

housed within the terminal cover provides con-

venient access for all user connections.
