2. Overview

2.2.3 Mounting Block

The Transmitter and Receiver are factory aligned and fixed to a mounting block. They should not be
disassembled. The mounting block has a top cover which can be removed to clean the Transmitter and
Receiver windows. Inside the mounting block there is an angled window (the beamsplitter) which reflects the
beam into the Receiver.
The mounting block has two features for functional checking - a gas cell and a slot for plastic test filters.
2.3 Heated Reflector Panel
The Heated Reflector Panel consists of a retro-reflector sealed in a double-glazed unit, with an integral heater
to minimise condensation and frosting.
The Reflector Panel should be mounted opposite the Transmitter and Receiver unit, and perpendicular to the
beam.
The Reflector requires a nominal 24V power supply.
