1.2 WARRANTY POLICY ADVANCED POLLUTION INSTRUMENTATION DIVISION 02024c Prior to shipment, Teledyne API equipment is thoroughly inspected and tested. Should equipment failure occur, Teledyne API assures its customers that prompt service and support will be available. COVERAGE After the warranty perio...

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 O3 molecule. The Model 460H uses a mercury lamp constructed so that a large majority of the light emitted is at the 254nm wavelength. Light from the la...

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 ...

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 M4...

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 con...

AC NEUTRAL EARTH GROUND AC POWER CONNECTOR AC LINE I/O CONNECTOR Figure 2-3 Electrical Connections 2.4 Electrical I/O Connections All user I/O connections are available on the 16 pin connector on the mainboard (See Figure 2-3 for location.) This connector can be unplugged from the header on the main...

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 ...

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 concentrat...

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 O3 readout The current ozone concentration is displayed in the 4 digit readout in the center of the display. The concentrati...

5.0 Serial Communications The M460H comes equipped with a powerful digital Serial Communications Port that can be used for Data Acquisition and for changing instrument configuration. This port can be configured for either RS232 or RS485(half-duplex) operation. See Section 2.4.4 for details on connec...

5.4 Command Reference 5.4.1 CAUTO Syntax < address >CAUTO< CR > Description Perform an Auto-Zero Calibration. Valid only if Auto-Zero option is installed in monitor. Data Parameters Sent None Response < address > : < success_flag > # < checksum >< CR > Example Com...

5.4.5 SETADDR Syntax < address >SETADDR : < new_address >< CR > Description Changes the communications address to a new value. Data Parameters Sent new_address is the new address for the monitor; Range for new_address is 1-9. Response < address > : < success_flag > # &l...

5.4.9 VLIST Syntax <address>VLIST<CR> Description Returns a verbose list of an internal configuration variables (VARs.) Data Parameters Sent None Response Var List (See Below) Example Command: 1VLIST< CR > Response: #0 analog_range = 15.0 #1 azero_enable = 0.0 #2 azero_period = 720...

5.4.10 VSET Syntax <address>VSET :<var_index>, <new_value><CR> Description Sets value of an internal configuration variable (VAR.) Data Parameters Sent var_index is index number for internal VAR (See VGET for index list) new_value new value for VAR. Response < address >...

6.0 Maintenance 6.1 Replacing the gas filter element The Model 460H is equipped with a gas filter on the ozone inlet. These filters accept 25mm diameter glass fiber elements. Only filter elements of borosilicate glass or quartz fibers should be used. When the instrument is first installed, the sampl...

7.0 Sensor and System Troubleshooting This chapter gives guidelines for diagnosing system and sensor malfunctions using the five digital Status Outputs provided by the M460H. All troubleshooting should be done after the M460H has been turned on and allowed to warm up for at least 15 minutes. 7.1 Sta...

7.3 Invalid Reading The normal state for the Invalid Reading output is OFF. If this output turns on, this indicates that the M460H is still operational, but a system fault or calibration fault exists that may make the current ozone reading invalid. The Invalid Reading output is turned on for any of ...

7.6 Status Output Summary Table Table 7-2 below is a logic truth table summarizing the recommended actions based on the states of the four status outputs. A ‘1’ indicates the output is ON, a ‘0’ indicates the output is OFF, and ‘X’ indicates the output is in either state. Table 7-2: Status Output Tr...
