The installation process consists of the following stages:
1

Preparation

2

Mechanical installation

3

Electrical installation

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

ACCESSORIES

A range of accessories to suit different applications and industrial environments is available as
follows. These may be ordered at any time and added on-site:

LCT Loop Configuration Tool (USB adapter)

LCT-485 (RS-485 Modbus RTU network interface)

Fixed and adjustable mounting brackets

Air purge collar

OPTIONS

The following options are available. Options are factory installed and must be ordered with
the sensor.

Certificate of calibration

Extended sensing head cable (25 m max. factory-fitted; contact Calex for
information about extending the cable)

Output cable (25 m max. factory-fitted cable; alternatively customer may
supply and fit output cable. Contact Calex for information)

OPTICS

The below chart shows the measured spot diameter at the given distances from the
sensing head and assumes 90% energy. The sensor may be used at longer distances
than shown below, with a larger measured spot size.
