START-UP
7 Start-up
This Section describes the standard start-up at the end of which the Gas Analyzer GM35
starts measuring operation.
7.1 Preparations
7.1.1 Required qualifications and further prerequisites
Previous training by SICK AG or a qualified sales partner is recommend for technicians and
engineers performing start-up. This training provides knowledge so that participants can
recognize and handle situations that demand measures going beyond the standard
procedures described here. Apart from the start-up itself, employees of SICK AG or trained
sales partners are also able to make recommendations for the actual measuring operation
as well as to define the maintenance interval based on the specific plant conditions.
Standard start-up
Each single measuring system is already configured to the individual application at the
factory and therefore the standard start-up procedure described in this Section can
however usually be performed by qualified engineers or measurement technicians without
requiring special training. Prerequisites are:
• Exact adherence to the application requirements specified in the order
• The possibility to consult a trained specialist of SICK AG or the respective sales partner
should special questions arise during start-up that go beyond the scope of the standard
procedures described here.
7.1.2 Start-up procedure overview
Once the general preparatory measures have been taken, which mainly involve checking
that the previous work has been carried out properly, a zero adjust on a gas-free measuring
path (the zero path) must be carried out for the measuring system. This can be done either
at the measuring point or another location, e.g. in a closed room. At the measuring point
itself, the purge air unit, SR-unit and reflector are then put into operation in succession.
Finally, the evaluation unit is switched on and checked; the EvU parameters can then be
set for individual demands.
7.2 Start-up steps overview
Prerequisites for successful start-up:
• Installation conditions match the requirements for the measuring system (temperature,
pressure).
• Measuring point must be accessible without danger or problems.
• The flanges with tube have been properly installed on the device and reflector side and
precisely aligned.
• All power supply and signal cables are installed and connected.
• The system, apart from the SR-unit, reflector and purge air fixtures which are attached to
the duct flanges later, must be fully installed and wired.
• The purge air supply must be ready to function.
