Page 13: Powering Up The Analyzer
5.2 Powering up the Analyzer 1. Verify the analyzer is set to the desired 110 VAC or 220 VAC selection by checking the voltage indication sticker. 2. For concentrations below 100 ppm, it is useful to let the analyzer “purge” by letting gas flow through it for about five minutes before the power and sensor are turned on. -
Page 14: Additional Capabilities
5.3 Additional Capabilities Your analyzer may be equipped with additional capabilities. Consult the Standard Features section on page 13 and the Options section on page 15 for information regarding: Analog Output Scaling for 0 to 1.0, 2.0 or 5.0 VDC ... -
Page 15: Standard Features
6 Standard Features The DF Series analyzers use a patented, non-depleting, coulometric sensor to detect oxygen in gas sample streams. The DF analyzer is generally tolerant of contaminants, as well as pressure and temperature fluctuations. However, the sample gas must be relatively clean, dry, and free of hostile components. -
Page 16: Analog Output
6.3 Analog Output The default setting for the analog signal output is 0 to 10 VDC. Alternate settings available when ordering are 0 to 1 VDC, 0 to 2 VDC or 0 to 5 VDC. The analog output is proportional to the oxygen reading of the analyzer. The analog output on a three range analyzer will be scaled to the “selected”... -

One percent is equivalent to 10,000 ppm. Table 2: Maximum Acid Gas Concentrations with Stab-El (in ppm) Contact Delta F for recommendations on using the Stab-El sensor on acid gases other than those listed above. If the acid gas components in your gas exceed the limits in Table 2 several approaches can be taken: ... -
Page 18: Alarms
7.2 Alarms The DF-110 can be equipped with one or two alarms. Alarm 1 can be factory configured for high O , low O , and Trouble. Alarm 2 can be configured for high O or low O In the standard oxygen alarm configuration: ... - Page 19 (Example: See the entry for the three range 0-100.0/1000.0/10000 PPM analyzer. If the analyzer is set to the 0-100.0 PPM range the alarm set point at Display + and Display - will be 0-100.0 PPM scaled over 0 to 1.000 VDC. So if the voltage happened to be 0.100 VDC then the set point would be 10.0 PPM.

Page 20: Alarm Relays
The life of the filter element is dependent upon the nature of the sample gas. Therefore, it is difficult to recommend a filter element replacement frequency. Delta F recommends to check the filter condition every several weeks initially until the demands of the application can be determined and a filter element replacement frequency can be established. -
Page 21: Flow Control Valve
The Flow Switch connections can be made directly at the flow switch or terminal strip, if equipped. The contacts are rated at 120 VAC or 120 VDC at 0.5 A resistive. 7.6 Flow Control Valve The upstream Flow Control Valve is mounted adjacent to the Flow Indicator. It may be used to control the gas flow rate in systems where the inlet pressure is less than 5 psi. -
Page 22: Isolated 4 To 20 Ma Output
(depending upon the configuration ordered). For gases heavier than Nitrogen the specific gas must be specified at time of order, and many heavy gases may be accommodated, with a few limitations. Consult Delta F, prior to ordering, for details. The scale factor adjustment control will be labeled with the factory configured scale factor (example: % N in Ethylene). -
Page 23: Adjusting The Gas Scale Factor Pot For Light Gases (He Or H )
In such a case, it would be appropriate to use an analyzer of the next highest range (e.g. 0-500 ppm). Consult Delta F for application specific details. Adjusting the Gas Scale Factor Pot for Light Gases 7.10.1... -
Page 24: Adjusting The Gas Scale Factor Pot For Gases Heavier Than Nitrogen
Figure 6: Gas Correction Factor Adjustment 7.10.2 Adjusting the Gas Scale Factor Pot for Gases Heavier Than Nitrogen 1) Open the front door. 2) Locate the View Ref. Toggle switch. See Figure 6. 3) Throw the toggle switch upward (toward the label that lists the scale factor gas) and observe the front panel display. - Page 25 Table 5: Gas Scale Factor Correction Values Disclaimer The method used to correct the calibration of the Delta F Oxygen Analyzer for measurement in non-nitrogen background gases is derived from a well known theoretical mass transfer equation. This equation accounts for the change in oxygen diffusion rates through different gases.
- Page 26 Questions regarding the calculation of a background gas correction factor for a specific application should be directed to the Delta F Customer Support Services Department at (781) 935-5808. NOTE: In light gas (H or He) backgrounds, the diffusion rate of oxygen will be greater than that in nitrogen, resulting in a higher absolute current generated by the sensor.

Page 27: Sample Gas And Plumbing Cautions
8.1 Condensation Like most gas analyzers, the DF series operation will be compromised if there is condensation in the sensor. If that possibility exists, the gas should be pre- conditioned. Several techniques are available. If the gas is a hydrocarbon, maintain the sample from 20°F to 40°F above its dew point. -
Page 28: Process Up-Sets (Oxygen Shock)
CAUTION After performing the leak test, open the up-stream valve slowly to slowly lower the pressure to the sensor. 8.4 Process Up-sets (Oxygen Shock) If a low range sensor is exposed to high concentrations of oxygen such as room air, it will enter an over range condition. The sensor may absorb excessive oxygen and it may take some time before it comes back “on-range”. -

Page 30: Analog Output (Rec + & Rec - ))
The 4 to 20 mA output is electrically isolated from all other analyzer outputs and from chassis (earth) ground. The maximum load resistance is 1K ohms. The analyzer provides a loop supply of approximately 28 VDC. Connections to the 4-20mA output should be made through a shielded, twisted pair with the shield tied to the Ground connection ( ). -
Page 31: Ground
9.1.7 Ground This is frame ground. All signals such as alarms, range indication, sensor off, analog and 4-20 mA outputs should be shielded and the shield should be tied to this terminal. To prevent ground loops, only connect the shield at this end. 9.1.8 Trouble Alarm The trouble alarm (if installed) is a combination of two alarms wired to a single output. -
Page 32: Secondary Electrodes (Sec El +, Sec El -)
The pump connector will have 110 VAC present even if the analyzer is running on 220 VAC. The pump connector is intended to power the Delta F 5 watt pump only. The pump wires should be in a shielded cable (separate from the sensor signal) with the shield attached to the frame ground. -
Page 33: Remote Control Of An External Pump
9.3.2 Remote Control of an External Pump If factory configured, an external pump (usually mounted on the sensor bracket) can be controlled via a remote, user provided switch connected in series with the Pump AC Hi and Pump AC Lo connections. The pump switch located on the front panel is in series with any external remote switch and must be turned on to allow remote control of the pump. -
Page 35: Maintenance And Calibration Checks
Calibration Checks 10.1 Sensor Maintenance Delta F analyzers require no routine maintenance other than the occasional addition of Delta F type Replenishment Solution to the sensor. Exposure to dry gas samples will gradually extract water from the sensor. Under these conditions, the frequency of additions will be slightly higher. -
Page 36: Calibration
10.2 Calibration All Delta F analyzers are calibrated with certified gas standards at the factory prior to shipment. No additional calibration is required. Depending on the application, the calibration should be checked approximately every six months using a gas of known concentration and high quality plumbing components. - Page 37 B. Adjust Span/Zero Calibration 1. Apply a calibrated span or zero gas to the analyzer. 2. Allow ample time for the analyzer to equilibrate. 3. If necessary, slowly turn the appropriate Span or Zero adjustment to obtain an oxygen reading that agrees with the Span or Zero calibration gas. 4.
-
Page 38: Adjusting The Span Calibration Pot (With The Gsf Option Installed)
10.2.2 Adjusting the Span Calibration Pot (with the GSF Option installed) For analyzers that have Scale Factor installed, the Span calibration potentiometer is located to the right of the Sensor Off switch. When performing a Calibration Adjustment (as described above) the Span pot does not have a Span Calibration Reference value, as a result there is no need to throw the View Ref toggle switch. -
Page 39: Theory Of Operation
11 Theory of Operation The Delta F Coulometric Sensor uses an ambient temperature oxygen reaction that is non-depleting. The cell produces a current flow that is determined by the number of oxygen molecules that are reduced at the cathode. The sensor reaction is driven by 1.3 volts applied across the electrodes. -
