Electrochemical analog carbon monoxide transmitters 1 General Overview The PolyGardCO analog gas transmitter is used for detection of carbon monoxide in the ambient air to warn of the presence of Carbon Monoxide gas.
2 Description The sensor portion of the PolyGard£ AT-1110 analog gas transmitter is a micro-fuel cell, which is completely sealed. The measurement is a gas-in-liquid chemical reaction rather than a surface area measurement. With no surface area to coat, this sensor retains its sensitivity to carbon monoxide even after prolonged exposure to clean air. The cell consists of a diffusion barrier, O-ring seal, electrolyte reservoir and three electrodes: sensing, counter and reference. The target gas, carbon monoxide, enters the cell through a diffusion barrier. The chemical process of the measurement is one of oxidation where one molecule of the target gas is exchanged for one molecule of oxygen. The reaction drives the oxygen molecule to the counter electrode, generating a DC microampere signal between the sensing and counter electrodes. This signal is linear to the volume concentration of the sensed gas rather than the partial pressure. The integrated two-wire transformer converts this DC microampere signal to a standard 4-20 mA signal. In some cases, biasing is required to maintain a voltage differential between the reference and sensing electrode in order to facilitate the necessary reaction in the cell. The transmitter electronics will provide the necessary bias voltage when configured for one of these sensor types. Most sensors produce a small amount of baseline current in clean air. This is adjusted out with the zero potentiometer on the transmitter. This oxidation at the electrodes causes wear of the sensor. Typical life for this sensor is approximately five years in normal operation. This will vary somewhat from sensor to sensor, with some working lifetimes less than five years and some greater than 5 years. This wear also changes the characteristics of the sensor, requiring periodic re-calibration. It is recommended that the sensor accuracy be verified every six months and recalibrated as necessary. Caution! Replacement sensor elements, which are not bias types, are shipped with a tiny spring of wire shorting the sensor and reference electrodes. This spring MUST BE REMOVED prior to installing the element into the sensor assembly.

Optional relay package AT-2R Ĭ: The PolyGard® AT-2R relay package is used in conjunction with the AT-1110 CO analog gas transmitter. The AT-2R provides the transmitters with two relay outputs with adjustable trip/setpoints, switching differential. Once plugged on the master PCB transmitter the relay outputs will change and notify if gas concentration exceeds the adjusted trip/setpoint. If the gas concentration falls below the adjusted trip/setpoint and switching differential the relays again will change state and fall back into their starting position. The relay will trigger on depending on its adjusted power mode. If de-energized it will trigger on. If energized it will trigger off (fail-safe mode) with increasing value. LED number 9 for relay R9 and LED number 10 for relay R10 indicates status of each relay.

3 Installation Note: x x
Avoid any force (e.g. by thumb) during operation or installation on the sensor element. This could destroy the element. Electronics can be destroyed through static electricity. Therefore, do not work on the equipment without a wrist strap connected to earth ground or standing on conductive floor.
3.1 Assembly information x x x
x x x x
The specific weight of carbon monoxide is almost the same as that of air (factor 0.967). Location of the sensor must conform to the layout of the area being monitored. Disregard the ventilation ratio! Do not mount sensor in the center of the airflow. In larger rooms, it might be necessary to install two or more transmitters where there is not adequate air movement. Do not mount in corners or directly in front of air inlets (e.g. doors, windows, open ramps, dampers, etc.). In areas with undefined air movement, it might be necessary to distribute several transmitters in a vertical and horizontal direction over the whole area to be monitored. Avoid locations where water, oil etc. may influence proper operation and where mechanical damage might be possible. Mounting height is five feet above floor (max. 6 feet). Provide adequate space around sensor for maintenance and calibration work. Duct model 4 mounting: Mount only in a straight section of duct with minimum air vortex. Keep a minimum distance of 3.5 feet (1m) from any curve or obstacle. Mount only in a duct system with a maximum air velocity of 2000 ft/min or less. Mounting must be made so that the airflow is in line with probe openings. (see Fig. 6, page 16)
3.2 Enclosure Un-screw cover of enclosure. Carefully unplug the basic PCB mounted on fixed terminal blocks. Screw the base vertically on wall or on a single gang electrical box. (see Fig. 5, page 16). For duct model Ĭ mounting: Cut a hole in the duct and install the probe in the hole. (see Fig. 7, page 16) Screw the housing to the duct using the mounting holes inside enclosure. Plug in the basic PCB and replace the cover after wiring connection is completed (see 4.2 wiring connection).

6 Inspection and Service 6.1 Inspection Inspection and service of the transmitters should be done by a trained technician and executed on a periodic interval. It is recommended that the sensor operation be verified at least every six months.
6.2 Calibration (See part 5.1 and 5.2) x Service at periodic intervals is to be decided by the person responsible for the gas detection system. x If span calibration voltage of 840 mV (see note below) is no longer attainable when applying 200 ppm Carbon Monoxide in air, then the sensor element has to be replaced. After the sensor element has been replaced a calibration is required. Note: If using a different level of span test gas ppm, or different sensor range, then the mV needs to be calculated.
6.3 Replacing of the sensor element Static electricity (see section 4.1). Sensor should always be installed without power applied: x x x x x x x
Unplug basic PCB EC-C carefully from the terminal blocks on the base. Unplug old sensor element out from the PCB EC-C. Take new sensor element out of original packing and remove the shorting wire on the sensor element contacts. Plug sensor element in the PCB EC-C. Plug the PCB EC-C in terminal block X4, X5 carefully. After sensor warm-up, turn potentiometer “Span” to its center position. (Turn the pot 25 rotations counter-clockwise, then 11 rotations clockwise to get centered.) Calibrate (see section 5.1).

The PolyGard® transmitters must be used within product specification capabilities. The appropriate operating and maintenance instructions and recommendations must be followed. Due to ongoing product development, MSR reserves the right to change specifications without notice. The information contained herein is based upon data considered to be accurate. However, no guarantee is expressed or implied regarding the accuracy of this data.
11.1 Intended product application The PolyGard® CO AT-1110 transmitters are designed and manufactured for control applications for energy savings and OSHA air quality compliance in commercial buildings and manufacturing plants (i.e.,detection and automatic exhaust fan control for automotive maintenance facilities, enclosed parking garages, engine repair shops, warehouses with forklifts, fire stations, tunnels, etc.).
11.2 Installers` responsibilities It is the installer`s responsibility to ensure that all PolyGard® transmitters are installed in compliance with all national and local codes and OSHA requirements. Installation should be implemented only by individuals familiar with proper installation techniques and with codes, standards and proper safety procedures for control installations and the latest edition of the National Electrical Code (ANSI/NFPA70). It is also essential to strictly follow all instructions as provided in the user manual.
11.3 Maintenance It is recommended that the PolyGard® transmitter performance check is done on a routine schedule. Any performance deviations may be serviced based on needed requirements. Re-calibration and part replacement may be implemented in the field by a qualified individual and with the appropriate tools. Alternatively, the easily removable plug-in transmitter card with the sensor may be returned for service to INTEC Controls.

This warranty does not apply to units that have been altered, had repair attempted, or been subjected to abuse, accidental or otherwise. The warranty also does not apply to units in which the sensor element has been overexposed or gas poisoned. The above warranty is in lieu of all other express warranties, obligations or liabilities. This warranty extends only to the PolyGard® transmitter. MSR and INTEC Controls shall not be liable for any incidental or consequential damages arising out of or related to the use of the PolyGard® transmitters.
