IS 50-LO plus / IGA 50-LO plus Manual Controls and Installation  16

The fiber has a color mark for correct connection to the pyrometer. This color mark has to be

mounted on the pyrometer’s side. On side of the optical head no mark or a black mark is

viewable.

Attention: The light guide end of the fiber optic cable as well as the socket/connector

and the optical head must always be protected with the caps when not connected!

Minimum Bending Radius

Red Blue Green

for short time (max. 250 °C): 50 mm 100 mm 150 mm

permanent (max. 250 °C) : 120 mm 300 mm 500 mm

wound up (max. 50 °C): 120 mm 300 mm 500 mm

Note: A hot fiber optic cable should not be exposed to continual movement!

Serial Number

The original fiber has a serial number which is also

on the pyrometer’s housing.

Attention: Faultless operation of the pyrometers is ensured only when using

components with the same serial number.

The system must be re-calibrated if the fiber optic cable or the optical head are

exchanged (service)!

Ambient Temperature

Fiber and optical head can withstand ambient temperatures up to 250 °C without cooling on the

optical head’s side.

3.3 Sighting

3.3.1 Laser targeting light

For exact measurement of the object temperature, the pyrometer must be aligned correctly

onto the object. For this alignment, the pyrometers are equipped with a laser targeting light.

This laser enables the simple and accurate alignment even onto small objects.

The laser marks the center of the measuring spot. The laser targeting light can be used during

operation without affecting the measurement.

The laser targeting light can be switched on and off either by pressing the button at the

housing or by using an external contact (see 3.1.1 Pin assignment for the connector on the back

side of the pyrometer) or via PC and the software InfraWin. After two minutes, the laser

targeting light switches off automatically.

If the converter cover is opened the laser targeting light can be switched with the button with

the  symbol. When the laser targeting light is switched on, the display shows “PILT”.
