3.4.1 Relay Contacts

Relay contacts are available for each alarm; these are as required by the application.

They are accessed on the terminals next to each relay see next to each terminal.

Relays may also be configured as failsafe or non-failsafe. The default alarm relay configuration is for latching mode, and failsafe. They may be reconfigured in the maintenance menu.

The PC Board is labeled for the relays in their un-energized state. If the relay is configured for failsafe, then this is also the alarm condition state. Non-failsafe configured relays in the alarm state, are the reverse of the PC board labeling. Note that the Fault(FLT) relay cannot be set to operate in a Non-Failsafe mode. Please see the

SPDT

, rated at 10Amp at 110

In addition, there is a fault relay, which changes state whenever the instrument is in a fault condition. The contact positions are noted on the circuit board next to each terminal. the non-fault state; the contact conditions given on the circuit board next to the terminal, are for the non-energized state, which is identical to the fault state.

These relay contacts can be used to operate auxiliary alarms or other functions. It is recommended that power for auxiliary equipment be supplied from an independent power source, separate from the wire exit, and use appropriate cable fittings. Be sure to note the location and depth of hardware inside the enclosure.

3.4.2 Optional 4-20mA Outputs

Isolated 4-20 mA outputs are available for data logging or other purposes. An output is supplied for each sensor supplied in a particular instrument, and can be added when a sensor is added in the field. These outputs are available on the Connector 1 for channels 1 & 2 and Connector 2 for channels 3 & 4.

4mA corresponds to a sensor reading at the bottom of the instrument range and 20mA corresponds to a full scale reading. Standard ranges are shown in

Wiring requirements are the same as for the relays.

3.5 Installation Verification

All instruments are calibrated at the factory. You may, if a calibration kit is available, calibrate the any and all gas channels of the instrument 24 hours after installation to verify proper installation and instrument operation. See for calibration instructions. Calibration is also recommended after the first month of operation. Subsequent calibrations should be performed every 3 months. The dew point sensor can not be calibrated in the field.

4.7 Fault Indications

4.7.1 Low Flow Indication

A flow sensor is used to furnish a low flow indication. When the sample air pressure drops below approximately 0.3 LPM, the fault light and audio alarm are activated, and the display flashes “Low Flow Alarm”.

4.7.2 Other Fault Indications

Other fault indications are associated with sensor zero and calibration activities, and are described in the maintenance

5.0

of this manual.

4.8 Dew Point Sensor Response

It is a characteristic of the than it does to add moisture to a sample by passing moist air though it. Therefore, the time response of the instrument to a step change from moist to dry air is slower, then the response to a step change from dry to moist air.

It is the nature of most materials to absorb and release moisture at different rates. In general, it typically takes longer for a system to establish moisture equilibrium when going form a high to low humidity than it does to go from low to high. The

PROA

2200

is no different. It may take up to 12 hours to establish moisture equilibrium when the instrument is first put on the air line if the Dew Point is less than 0°F. The sensor T90 response time is 10 seconds for a –40° to +50°F step change and 240 seconds for a +50° to –40°F step change. The delivery apparatus such as regulators, piping and tubing account for the additional response time of the instrument as a system.

PROA

2200

that it takes more time to extract moisture from a sample by passing dry air through it,

4.9 Hydrocarbon Sensor Response

If a Hydrocarbon (HC) sensor is supplied with the vapors with an ionization potential (IP) of 10.6 eV or less. Hydrocarbons with an IP of greater then 10.6 eV will NOT be detected. Please see Appendix B for a list of common gases and vapors and their respective IP rating. Unless otherwise noted Isobutylene is used as a calibration and reference gas.

5.0 Maintenance

The

2200

requires periodic sensor calibration and replacement. Calibration of toxic gas and oxygen sensor should be performed immediately following installation, one month after installation and every 3 months thereafter. HC sensor should be calibrated on a monthly bases. Oxygen and CO sensor have an estimated lifetime of 1 – 2 years. The CO2 sensor has an estimated lifetime of 3 years. Sensors should be replaced when they will not calibrate or shortly before the end of their estimated lifetime.

The dew point probe (sensor) can not be field calibrated. Dew point sensors should be replaced every two years.

5.3 Calibration for CO, O

HC and CO2 (Gas Channels)

Calibration is the process of setting the instrument up to read accurately when exposed to a target gas. This is a two step process. A Low Calibration sets clean air reference point and the High Calibration function sets the sensitivity of the instrument. Proper calibration requires that these two steps be preformed and successfully completed.

Calibration equipment is available from

5.5 Dew Point Sensor

Unlike the CO and O2 sensors, the dew point sensor cannot be field calibrated. To assure correct performance, the dew point sensor should be replaced every two years.

5.6 Flow Control Orifice / Pre-filter

A 0.005-inch diameter orifice is used to set the flow rate and to drop the air pressure. A pre-filter is in line to help prevent clogging. In well-maintained medical air systems, this orifice should not clog. However, if difficulty is experienced in maintaining flow rate with assured inlet pressure, remove air pressure from the equipment and examine this orifice and prefilter; replace it if necessary.

Orifice location will depend on instrument sensor configuration. Orifice and pre-filter are located at the output point of the dew point probe manifold or on the inlet line to the gas sensor manifold.

Appendix A: CO Characteristics

The Characteristics and Effects of Carbon Monoxide Carbon monoxide is a colorless odorless toxic gas generated by incomplete combustion of a hydrocarbon fuel in air. It may be

present where internal combustion engines, furnaces, boilers, and other combustion devices are present. It is toxic when inhaled because of its great affinity to hemoglobin, the oxygen carriers in the red cells of the blood. CO replaces the oxygen normally carried by the hemoglobin, and thus inhibits the delivery of oxygen throughout the body; the victim suffers from oxygen deficiency, and may die from asphyxiation. The symptoms and degree of danger resulting from exposure to CO depend upon the concentration of the gas and the length of exposure; this is shown in employed to warn the user of the presence of CO, and to facilitate the assessment of the degree of danger that he or she is exposed to.

Based upon knowledge of the effects of CO, the Occupational Safety and Health Authority (OSHA) has set limits on exposure to CO in the workplace. These are 35 ppm (parts CO per million parts air) as an time weighted average for an eight hour day, and a maximum exposure of 200 ppm. For compressed air line applications, OSHA requires Grade D breathing air supplied, using a Compressed Gas Association (CGA) definition (G-7.1). Depending on interpretation of the OSHA respiratory standard, 10 ppm and 20 ppm CO have been used as maximum limits and standard instrument alarm points.

If a CO sensor is installed, the but cannot be set below 5 ppm or above 50 ppm.

The curves below are for percent Carboxyhemaglobin with 50% being the top curve, 5% the bottom. %COHb is a measure of the amount of hemoglobin occupied by CO rather than oxygen. CO effects upon children, adults engaging in physical activity, and smokers, are more pronounced.

Returning an Instrument for Repair

ENMET instruments may be returned to the factory or any one of our Field Service Centers for regular repair service or calibration. The ENMET Repair Department and Field Service Centers also perform warranty service work.

When returning an instrument to the factory or service center for service, paperwork must be included which contains the following information:

 A purchase order number or reference number.  A contact name with return address, telephone and fax numbers  Specific instructions regarding desired service or description

of the problems being encountered.

 Date of original purchase and copy of packing slip or invoice

for warranty consideration.

 If a price estimate is required, please note it accordingly and be

sure to include a fax number.

Providing the above information assists in the expedient repair and return of your unit.

Failure to provide this information can result in processing delays.

ENMET charges a one hour minimum billing for all approved repairs with additional time billed to the closest tenth of an hour. All instruments sent to ENMET are subject to a minimum evaluation fee, even if returned unrepaired. Unclaimed instruments that ENMET has received without appropriate paperwork or attempts to advise repair costs that have been unanswered, after a period of 60 days, may be disposed of or returned unrepaired COD with the evaluation fee. Service centers may have different rates or terms. Be sure to contact them for this information.

Repaired instruments are returned by UPS/FedEx Ground and are not insured unless otherwise specified. If expedited shipping methods or insurance is required, it must be stated in your paperwork.

Note: Warranty of customer installed components.

If a component is purchased and installed in the field, and fails within the warranty term, it can be

returned to ENMET and will be replaced, free of charge, per ENMET’s returned goods procedure.

If the entire instrument is returned to ENMET Corporation with the defective item installed, the item will

be replaced at no cost, but the instrument will be subject to labor charges at half of the standard rate.
