End of line resistance
For the last detector, set switch #8 (EOL RESISTOR) to ON.

2.6 Scope of use

The OLCT 10N may be used only with the TELEDYNE OLDHAM SIMTRONICS MX 43 or MX
32v2 measurement and alarm controller.
The sensors have certain limitations; it is essential to fully recognize these limitations.
Presence of specific components
• Vapor from components containing silicone or sulfur can affect the catalytic sensors and
thereby distort measurements. If sensors have been exposed to these types of compound,
inspection or calibration will be necessary.
• High concentrations of organic solvents (e.g. alcohols, aromatic solvents, etc.) or
exposure to quantities of gas greater than the specified range of measurement can
damage the electrochemical sensors. Inspection or calibration is then recommended.
• In the presence of high concentrations of carbon dioxide (CO2 > 1% vol.), the oxygen-
measuring electrochemical sensors can slightly overestimate the concentration of oxygen
(0.1 to 0.5% vol. O2 overestimate).
Operation under low oxygen levels
• If an electrochemical sensor is used in an atmosphere containing less than 1% vol. oxygen
for over one hour, the measurement may be an underestimate.
• If a catalytic sensor is used in an atmosphere containing less than 10% vol. oxygen, the
measurement may be an underestimate.
