Page 10: Overview
Overview The zirconia oxygen analyzer utilizes a solid electrolyte consisting mainly of zirconia (ZrO ) which conducts only oxygen ions at a high temperature. It is an oxygen sensor which measures, based on the principle of an oxygen concentration cell, the electromotive force produced due to the difference in oxygen concentration between the measured gas and reference air. -
Page 11: Specifications
Output signal: 4 to 20mA DC and 0 to 1V DC linear connected to infrared gas analyzer or direct output from sensor of the ZX8D. Sensor output: Logical output of zirconia sensor (with sensor temperature of 800°C) E = 50.74 log 20.6... - Page 12 Safety, EMC and RoHS conforming standards (Only ZX8D-□*D) Installation altitude: 2000 m or less Pollution degree: Installation category: Note: Installation category, called overvoltage category, specifies impulse withstanding voltage. Category II is for electrical equipment. Pollution degree indicates the degree of existence of solid, liquid, gas or other inclusions which reduce dielectric strength.

Page 14: Installation
Installation WARNING This unit is not explosion-proof type. Do not use it in a place with explosive gases to prevent explosion, fire or other serious accidents. CAUTION This unit should be installed in a place which conforms to the conditions noted in the instruction manual. -
Page 15: Piping
• This analyzer is of an indoor structure. When installing outdoors, select a place which is not exposed to rain or water or use a protective cover. • Select a clean place which is free from corrosive gas or combustible gas. Piping Connect pipes to the gas inlet and outlet at the bottom of the unit. -
Page 16: Sampling
Sampling WARNING • This unit is not explosion-proof type. Do not use it in a place with explosive gases to prevent explosion, fire or other serious accidents. • When combustible gases are contained in measuring gas, check the gas composition and instrument specifications before use, or else the best performance may not be obtained or there may be a danger of explosion. -
Page 17: Wiring Method
Wiring method CAUTION • Wiring work must be performed with all the power supplies to OFF to prevent electric shocks. • Be sure to perform class D grounding. Otherwise electric shock or malfunction may result. • During installation work, care should be taken to keep the unit free from entry of cable chips or other foreign objects. -
Page 18: Operation
Operation WARNING • When noxious gases such as CO or other gases are contained in the calibration gas, be careful when venting or handling the instrument to avoid poisoning. • When combustible gases are contained in measuring gas, check the gas composition and instrument specifications before use, or else the best performance may not be obtained or there may be a danger of explosion. -
Page 19: Maintenance
Maintenance WARNING When noxious gases such as CO or other gases are contained in the calibration gas, be careful when venting or handling the instrument to avoid poisoning. CAUTION • If the cause of any fault cannot be determined despite reference to the instruction manual, be sure to contact local sales representative or service office. -
Page 20: Cleaning Gas Outlet
Check for continuity between 3 and 4 of the oxygen sensor - it should be around 2Ω. When disconnected, replace the oxygen detector. Cleaning gas outlet Sulfate mist or oxide may be precipitated at the pipe output, depending on the components of measuring gas. -
