ALIGNMENT AND COMMISSIONING
3.7.1 General
In order to avoid unnecessary problems, alignment and commissioning of Searchline Excel
gas detectors should only be performed by personnel trained by Zellweger Analytics.
To ensure optimum performance the gas detector Transmitter and Receiver units must be
accurately aligned with a clear line of sight between them.
The Transmitter unit is first aligned with the Receiver using a telescope attached to the body of
the unit. The telescope is then fitted to the Receiver and the alignment procedure repeated.
The Handheld Interrogator is then attached to the Receiver to finally commission the equipment
and, depending on the type of Receiver, may need to be used to assist in fine-tuning the
alignment.
The procedure can be performed by a single technician.
Each gas detector unit features a mounting assembly that allow both coarse and fine mechanical
adjustment in the horizontal and vertical directions as shown in the subsequent diagram.
