1.3 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 O molecule. The Model 460H uses a mercury lamp 3 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 being measured is passed. The ratio of the intensity of light passing through the gas to a reference measurement which does

2.0 Installation Upon receiving the Model 460H please verify that there is no apparent shipping damage. (If damage has occurred please advise shipper first, then Teledyne API.) 2.1 Mechanical Installation 1. Mount the enclosure securely to a vertical surface. Figure 2-1 below shows the locations of the four mounting holes. All four mounting holes should be used to secure the monitor. 6.050 [153.67] 10.700 [271.78] Figure 2-1 Mounting Hole Locations P/N 03662D Teledyne API Model 460H

2.2 Pneumatic Connections 1. Connect a ¼” exhaust line to the fitting labeled ‘Exhaust.’ This line should be vented to an outside area, since the exhaust gas may still contain trace levels of ozone that may not be completely removed by the built-in the ozone scrubber. CAUTION Exhaust gas from the M460H may contain dangerous levels of ozone! 2. Connect the ozone delivery line to the ¼” inlet fitting labeled “Ozone Inlet” on the bottom face of the enclosure (See Figure 2-2.) The ozo

2.3AC Power Connection Connect AC power to the instrument. A hole is provided on the bottom face of the enclosure for installing a ½” conduit fitting for routing the electrical wiring into the instrument. In order to maintain the IP (NEMA4X) rating of the enclosure, an appropriate sealed conduit connector should be used. Figure 2-3 below shows the location of the three terminal connector for the AC power. It is recommended that if multi-strand wires are used to make the AC connections,

2.4.2 Digital Status Outputs The M460H has four digital status outputs for indicating error and operational status conditions. These outputs are in the form of opto-isolated open-collector transistors. They can be used to drive status LED’s on a display panel or interface to a digital device such as a Programmable Logic Controller (PLC). Figure 2-4 shows the most common way of connecting the digital outputs to an external device such as PLC. Note: Most devices, such as PLC’s, have in

2.4.3 Control Inputs There are 2 digital control inputs on the I/O connector; they are labeled ‘Zero Input’ and ‘Aux Input.’ The control inputs are used for remote control of the M460H by a device such as a PLC. These inputs are triggered by providing a contact closure or low impedance current path between the Input and the Gnd pin. This can be done by using a mechanical switch or isolated transistor type output from another device, such as a PLC. Never connect a voltage level output f

2.4.4 RS232/RS485 Serial Communications Port A bi-directional RS232/485 Serial Port Interface is provided that can be used for data acquisition and instrument control. All that is required to use this interface is a computer with a serial communications port (COM port) and terminal software. Three pins are provided on the I/O connector for serial communications as shown in Table 2-3. Table 2-3 Serial Port Pins Label Description SERIAL TX Serial Transmit (RS485 – A) SERIAL RX Serial Rec

3.0 Startup Perform the following steps when fist installing the M460H ozone monitor or when bringing the monitor back into service. 1. Turn on power to the monitor. The display will briefly display the “API” logo followed by the software version. The display will then begin showing ozone concentration. 2. Establish a flow of zero gas to the monitor. Zero gas can be oxygen or clean, dry air. If monitor cannot be disconnected from an ozone generator, then establish flow through the

4.0 Operation The M460H has been designed for simple and trouble-free operation. The Sections below detail the operational features of the M460H. 4.1 Front Panel Display 4.1.1 O readout 3 The current ozone concentration is displayed in the 4 digit readout in the center of the display. The concentration is displayed in the currently selected units, either wt% or g/Nm3. 4.1.2 Pressure Display The pressure inside the measurement cell can be displayed on the readout by pressing and hol

4.2 Auto-Zero Operation The Auto-Zero feature allows the monitor to operate unattended for extended periods of time. This feature automatically performs a Zero Calibration at specific intervals (default interval is 12hrs.) The monitor does this by opening a solenoid valve to allow externally supplied Zero Gas to purge the monitor and then automatically performs a Zero Calibration. 4.2.1 Auto-Zero Installation In order for this feature to function properly, external, pressurized zero g
