AC voltage. Connect OMS and Sensor Before Powering To avoid damage to the sensor: • Do not power the OMS with the sensor unplugged from the main PC board. • Do not connect the sensor to the PC board while the OMS is powered. -
Page 31: Keep Away From Silicone Compounds
When calibrating or challenging the OMS: • Do not expose the OMS to flow rates that exceed a half-liter per minute (500 cc per minute). • When testing sample draw monitors use an on-demand regulator to expose the span gas to the OMS. -
Page 32: Keep Away From A Water Stream
Keep Away From a Water Stream Do not expose the sensor directly to a water stream. Cover and protect the OMS and power supply if located in an area that requires wash downs. Contact ETS-Lindgren for information on purchasing a waterproof enclosure. -
Page 33: Installation
The OMS must be installed outside of the shielded enclosure. Mounting the OMS The Sample Draw Oxygen Monitoring System (OMS™) is designed primarily for wall mounting and should be installed at a height convenient for operation, maintenance, and viewing of the instrument display. The transmitter and sensor should be installed in a location where gas leaks are likely to occur or where released gases may accumulate. -
Page 34: Transmitter And Sensor
Leave clearance room on the bottom of the OMS for the filter, which adds an additional 3.75 inches. The OMS should be mounted no closer than 12 inches above floor level. Airflow within the monitored area, the characteristics of the gas (lighter or heavier than air), and the position of workstations and personnel should all be considered in determining the most suitable installation location. -

Page 49: Operation
The joystick has a built-in delay to prevent accidental tampering with the menus; deliberate entries are required. The Sample Draw Oxygen Monitoring System (OMS™) uses an 8-position joystick with a center pushbutton for selecting menus and changing values. The joystick is programmed to standard protocol as follows: + Plus Push the joystick in this direction to increase the value. -
Page 50: Main Operation Mode
Internal Sample Flow Rate The OMS has an internal sample pump flow rate that is programmed at the factory and cannot be changed in the field. A flow sensor on the relay board continually monitors flow rate and when a loss of flow is detected, a signal is sent to the fault relay and the front mounted LED will activate. -
Page 51: Instrument Faults
24 VDC ± 0.5 Volts. A voltage that is too low or too high will activate a Supply Voltage Out of Range fault and disable the OMS. The OMS incorporates a number of self-checking features to ensure reliable operation. If a fault condition is detected, the analog output signal is altered as follows: All system faults are displayed on the front panel. -
Page 52: Loss Of Power Indicator
Loss of Power Indicator If the OMS loses 24 VDC power, the 4–20 mA analog output signal drops to 0 mA. The display will show a blank screen. Alarm Reset If the OMS is supplied with the optional alarm relays, when the monitors alarms are activated, the built-in alarm relays, panel mounted LEDs, and optional audio horn will also activate. -
Page 53: Programming The Oms
Only qualified personnel should program the OMS. The Sample Draw Oxygen Monitoring System (OMS™) is supplied with user-selectable settings to adjust the alarm settings, 4 and 20 mA output, and minor sensor adjustments. The settings are arranged in menus that are accessed by moving the joystick. -

Page 74: Set Sensor Adjust
ENSOR DJUST Warm up the OMS for two hours prior to making any adjustments to the sensor. Sensor Adjust sets the oxygen readout to a known concentration. It is recommended to adjust the oxygen display to ambient oxygen levels of 20.9%. -
Page 75: Sensor Verification
Verification of the Sample Draw Oxygen Monitoring System (OMS™) to 20.9% oxygen is constantly being performed. As the sensor ages over time, it may require a slight adjustment to 20.9%. The OMS also requires periodic testing with nitrogen to verify the cells response to 0% oxygen. -
Page 76: Required Gas And Equipment
The required gas and equipment are available from your gas supplier or from Air Liquide at 800-638-1197. Nitrogen and an on-demand regulator are recommended to expose the OMS to a known span gas. You may purchase both items from your gas supplier or from Air Liquide. -
Page 77: Sensor Verification To Nitrogen
ETS-Lindgren recommends challenging the OMS with nitrogen every 6 to 12 months. The filter on the OMS has a 1/4-in male tube fitting designed to connect sample tubing from a nitrogen cylinder. Expose the OMS to nitrogen using the on-demand regulator. The reading will drop off to 1% or below in less than one minute when the sensor is exposed to pure nitrogen. -
Page 78: Sensor Verification To Known Concentration Of Oxygen
Protect the OMS from wind and high airflow when gas calibrating with test gas. Test the OMS in an upright position to allow the span gas to fully saturate the sensor. To see the exact span gas concentration the OMS must be completely immersed into a span gas environment. -
