2.2. Approvals This section presents Safety and Electromagnetic Compatibility (EMC) compliance approvals for the Model 465M monitor. 2.2.1. Safety IEC 61010-1:2001, Safety requirements for electrical equipment for measurement, control, and laboratory use. CE: 2006/95/EC, Low-Voltage Directive North American: cNEMKO (Canada): CAN/CSA-C22.2 No. 61010-1-04 NEMKO-CCL (US): UL No. 61010-1 (2nd Edition) 2.2.2.
3. PRINCIPLE OF OPERATION The detection of ozone molecules is based on absorption of 254 nm UV light due to an internal electronic resonance of the O3 molecule. The M465M uses a mercury lamp constructed so that a large majority of the light emitted is at the 254nm wavelength. Light from the lamp shines through an absorption cell through which the sample gas is passed.
length determines how many molecules are present in the column of gas in the absorption tube. The intensity of light is converted into a voltage by the detector/preamp module. The voltage is converted into a number by a high resolution A/D (analog-to-digital) converter. The digitized signal, along with the other variables, is used by the CPU to compute the concentration using the above formula.
4. GETTING STARTED The M465M is shipped with the following standard equipment: 1. Power cord (Rack mount version only) 2. Instruction manual. Upon receiving the M465M please do the following: 1. Verify that there is no apparent shipping damage. (If damage has occurred please advise shipper first, then Teledyne API.) 4.1. Mechanical Installation (for NEMA 4X Enclosure) Mount the enclosure securely to a vertical surface. Figure 4-1 shows the locations of the four mounting holes.
Figure 4-1: M465M Mounting Hole Locations and Dimensions 4.2. Mechanical Installation (19” Rack Version) The Rack Mount version of the M465M was designed to be operated as a bench-top monitor or to be mounted in a standard 19” RETMA instrumentation rack. For rack installations, the four mounting feet should be removed from the bottom of the monitor. 4.2.1. Ventilation Clearance When installing the M465M be sure to leave sufficient ventilation clearance.
4.3. AC Power Connection (for Monitors in NEMA 4X Enclosures) CAUTION Disconnect power to the AC mains before making or removing any electrical connections to the M465M. CAUTION A proper earth ground connection must be made to the receptacle labeled “Earth Ground” on the 3 pin AC connector. Failure to do so may result in a shock hazard and malfunction of the monitor 1.
3. For the NEMA configuration, the electrical connection must be hard-wired to the 3-pin connector on the mainboard labeled J23. AC power connection to the monitor should be made with 12-14 AWG stranded copper wire, connected to the monitor as follows: a. Earth Ground (green): Connect the earth ground wire to the screw terminal lug on the chassis as shown in the Figure below. Do not connect the earth ground wire directly to the PCB connector on the mainboard PCB. b.
should light with a sequence of messages, including the instrument serial number and software revision. (When the instrument first powers up, the display will show ‘xxxx’, indicating that the instrument is in start-up mode, waiting for the UV detector readings to stabilize). After the start-up period, the instrument will begin displaying the ozone concentration and the optional stream selector will begin operating, if installed. 4.4.
Figure 4-4: Pneumatic Connections, NEMA Configuration 4.4.1. Ozone Inlet Connection Sample gas connections are made to the ¼” stainless steel compression fitting on the rear panel. (See Figure 4-3 and Figure 4-4) 1/4" O.D. FEP (Teflon) or Stainless Steel tubing is recommended to connect the sample source to the monitor. Any fittings used in the sample lines should be constructed of Stainless Steel or Teflon.
4.4.2. Exhaust Connection Connect a ¼” OD vent line to the “Exhaust” fitting on the rear panel. This line must be vented outdoors or to an appropriate discharge system capable of handling ozone. Local regulations regarding the discharge of ozone to the atmosphere must be observed. Note that the monitor may be equipped with an internal ozone scrubber for removal of ozone from the exhaust stream. For safety reasons, the exhaust port must still be vented appropriately as described above.
Figure 4-6: NEMA Electrical I/O Connections P/N 06160D DCN6409 Teledyne API Model 465M O3 Monitor Instruction Manual - Page 22
4.5. Electrical I/O Connections 4.5.1. Location of I/O Connectors in the NEMA Configuration In the NEMA configuration of the M465M, the I/O connectors are located internally in the instrument. See Figure 4-6 for their location. Connection to these terminals is usually made via a conduit connection to the NEMA enclosure. A standard conduit penetration may be added to one of the walls of the enclosure for this purpose, or the existing penetration may be used.
The analog output is automatically scaled to the range of the instrument, i.e. if the monitor range is 1000 PPB, then 5V would correspond to 1000 PPB and 0V would correspond to 0 PPB. See Section 7.2.5 for information on changing the range of the monitor. 4.5.3. Status Outputs There are four instrument status outputs located at the “General I/O” connector. These status outputs mirror the state of the four diagnostic LED’s on the front panel.
4.5.4. Hi-Current Relay Outputs Three form C relay outputs are provided on the rear panel on the nine pin connector (See Figure 4-5). The relays are labeled “Relay 1,” “Relay 2,” and “Relay 3.” The relays are dry contact type form C (SPDT) relays with Normally Open (N.O.), Normally Closed (N.C.) and Common (COM) contacts. The relays are capable of driving loads of up to 250VAC, 5A. For maximum contact life, the relays should only be used to drive resistive loads.
With the instrument configured for RS485, connection can be made to the DB-9 connector, labeled “RS232/485”, or to the three “COM” pins on the “General I/O” connector. See Section 8.2 for additional details. 4.5.5.3. Ethernet Connection With the instrument configured for Ethernet, connection should be made to the RJ-45 port labeled “Ethernet.” Connection can be made using a standard Category 5 or better network patch cable.
5. FREQUENTLY ASKED QUESTIONS 1. Q: How long does the UV Lamp last? A: The typical lifetime is about 2-3 years. The lamp output will steadily decrease until lamp adjustment can no longer be performed. The "Check Lamp" warning LED will tell the operator when this adjustment should be attempted. When this adjustment can no longer be performed, the lamp should be replaced. See Chapter 9 for more information.

10.2. Troubleshooting Using Front Panel Status LED’s or Status Outputs The M465M has 4 front-panel status LED’s that reflect the current operating status of the monitor, and indicate fault conditions. There are also four relay Status Outputs on the rear panel (or internally in the NEMA configuration) that also reflect the state of these status LED’s. See Section 4.5.3 for more information on the Status Outputs.
10.2.1. Sensor OK The Sensor OK LED indicates the status of the O3 sensor module in the monitor. The normal state of this LED (or Status Output) is On. If this LED remains off after the normal warm-up period, then a failure has occurred and the monitor should be removed from service and repaired. The most common cause of this warning is a failure of the UV Lamp. A UV Lamp Adjustment (See Section 9.4) should be attempted.
10.2.4.1. Pressure Too High The monitor inlet is being pressurized. The monitor inlet should be allowed to sample gas at ambient pressure. Disconnect all sample lines from the monitor and read the pressure again. If the value then drops to within the acceptable range, then one of the sample lines is at elevated pressure. If the inlet is being pressurized, then the design of the sample system should be reviewed and corrected. 10.2.4.2.
11. CALIBRATION CAUTION RISK OF ELECTRICAL SHOCK. THE OPERATIONS OUTLINED IN THE FOLLOWING SECTIONS OF THIS CHAPTER ARE TO BE PERFORMED BY QUALIFIED MAINTENANCE PERSONNEL ONLY! 11.1. Factory Calibration The M465M is calibrated to internal T-API calibration standards to shipment. A calibration certificate for your instrument can be purchased from Teledyne API if required.
