OVERVIEW The SPS 4001B provides the capability of performing automatic, timed or on
demand, calibrations of a single Oxymitter 4000 without sending a technician to the probe site.
The SPS 4001B replaces the SPS 4000, a similar unit with exposed analog devices mounted to a stainless steel support bracket. The operating parameters of the SPS 4000 and SPS 4001B are identical. All SPS units require additional calibration system components. These components, available from Emerson, are listed in Table 1-1.
The SPS 4001B is fully enclosed in a NEMA cabinet suited for wall-mounting. The enclosure provides added protection against corrosive atmospheres and incidental impact damage.
Emerson has offered multiprobe autocalibration sequencer systems for many years. These autocalibration systems are most cost effective for boilers and other combustion processes that utilize many probes. Users with only one probe per combustion process can take advantage of Emerson's autocalibration capability with the SPS 4001B.

Calibration Gas Solenoids
The 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.
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 disconnected gas line, etc. Calibration is prohibited when calibration gas pressure is low.
Circuit Board
The circuit board converts the incoming line voltage from AC to DC for use by the solenoids, terminations, and the programmable logic device. The power circuit is protected by a 1.6 A, 250 V, fast acting fuse.
The board contains a programmable logic device (PLD) that has the electronics to energize and deenergize the solenoids based on a signal from the Oxymitter 4000.
A terminal strip provides convenient access for all signal and power user connections.
Calibration Gas Flow Meter
The calibration gas flow meter indicates the flow rate of calibration gas flowing to the Oxymitter 4000.
Reference Air Flow Meter
The reference air flow meter indicates the amount of reference air continuously flowing to the Oxymitter 4000.
Pressure Regulator
The pressure regulator ensures the instrument air (reference air) flowing to the Oxymitter 4000 is at a constant pressure [25 psi (172 kPa)]. The regulator also has a filter to remove particulates in the reference air and a drain valve to bleed the moisture that collects in the filter bowl.

THEORY OF OPERATION
The Oxymitter 4000 is one of the few instruments found in industry that permit the permanent piping of a calibration standard into the probe. Most instruments measuring pressure, flow, or temperature, require that a calibration standard be brought to the instrument or that the instrument be taken to the calibration source in the instrument shop.
The permanent calibration gas connections allow for autocalibrations to occur without operator intervention. The following paragraphs describe how an Oxymitter 4000 is autocalibrated when used with the SPS 4001B.
In addition to the calibration methods available via the Oxymitter 4000 keypad, HART communicator, AMS software, or a remote contact, the SPS 4001B works in conjunction with the Oxymitter 4000's CAL RECOMMENDED feature to perform an autocalibration.
This feature automatically performs an impedance check every hour on the Oxymitter 4000. If a calibration is recommended and its contact output signal is set for "handshaking" with the SPS 4001B sequencer, the Oxymitter 4000 sends a signal to the sequencer. The sequencer automatically performs a calibration upon receiving the signal. Therefore, no human interface is required for the automatic calibration to take place.
See Figure 1-3. When a calibration is required, the Oxymitter 4000 sends a signal to the programmable logic device (PLD) on the interface board of the sequencer. The PLD energizes the calibration gas 1 (high O2) solenoid. Calibration gas 1 then flows through the sequencer to the Oxymitter 4000. The Oxymitter 4000 measures the oxygen content of calibration gas 1 and sends a signal to the sequencer indicating that it received the gas. When the sequencer receives the signal, the PLD deenergizes the calibration gas 1 solenoid.
Next, the PLD energizes the calibration gas 2 (low O2) solenoid, and calibration gas 2 then flows through the sequencer to the Oxymitter 4000. The
Oxymitter 4000 measures the oxygen content of calibration gas 2 and sends a signal to the sequencer indicating that it received the gas. After measuring the two calibration gases, the Oxymitter 4000 automatically makes an internal calibration adjustment and sends the signal to the sequencer. When the sequencer receives the signal, the PLD deenergizes the calibration gas 2 solenoid.

GAS CONNECTIONS Use the following procedures to connect the reference air and the calibration
gases.
Reference Air (Figure 2-1)
The Oxymitter 4000 requires a source of reference air that is constantly
20.95% O2. Clean and dry instrument air provides the most stable source of reference air. If instrument air is unavailable, the reference air port of the probe can be left open, permitting ambient air to passively diffuse into the probe.
1.
Connect the instrument air supply to the INST AIR IN port of the manifold.
2.
The pressure regulator is factory set at 25 psi (172 kPa). If necessary, readjust by turning the knob on the top of the regulator until the desired pressure is obtained.
3.
Next, connect the reference air from the REF GAS OUT port of the manifold to the REF GAS port on the Oxymitter 4000.
Calibration Gas (Figure 2-1)
1.
Connect O2 calibration gas 1 (high calibration gas) to the HI GAS IN port on the manifold. Ensure the calibration gas pressure is set at 25 psi
(172 kPa).
2.
Connect O2 calibration gas 2 (low calibration gas) to the LOW GAS IN port on the manifold. Ensure the calibration gas pressure is set at 25 psi
(172 kPa).
3.
Connect the calibration gas from the CAL GAS OUT manifold fitting to the check valve connected to the CAL GAS port on the Oxymitter 4000.
Do not exceed maximum pressure for instrument air. Failure to limit pressure could result in equipment failure, serious injury or death.
Instrument air is not recommended for the high calibration gas. Do not use 100% nitrogen as a low gas (zero gas). It is suggested that the low (zero) gas be between 0.4% and 2.0% O2. Do not use gases with hydrocarbon concentrations of more than 40 parts per million. Failure to use proper gases will result in erroneous readings.
