INSTALLATION

The installation process consists of the following stages:

•

Preparation

•

Mechanical installation

•

Electrical installation

Please read the following sections thoroughly before proceeding with the installation.

PREPARATION

Ensure that the sensor is positioned so that it is focused on the target only.

DISTANCE AND SPOT SIZE

The size of the area (spot size) to be measured determines the distance between the sensor

and the target. The spot size must not be larger than the target. The sensor should be

mounted so that the measured spot size is smaller than the target. We normally recommend

that the target should be at least twice the size of the measured spot for maximum accuracy.

The sensor is designed to operate in ambient temperatures from 0°C to 120°C (XCF models:

70°C).

Avoid thermal shock. Allow 20 minutes for the unit to adjust to large changes in ambient

temperature.

Smoke, fumes or dust can contaminate the lens and cause errors in temperature

measurement.

In these types of environment the air purge collar should be used to help keep the lens clean.

ELECTRICAL INTERFERENCE

Do not operate the sensor near large electromagnetic fields (e.g. around arc

welders, generators and induction heaters). Electromagnetic interference can cause

communication errors.
