SAFETY CONSIDERATIONS
Cautions and warnings presented in the Sensor/Analyzer and the MultiGard 5000 System
sections of this instruction manual require special attention by the system operator.
All cautions
and warnings must be read and understood before the MultiGard 5000 System is operated and
placed into service.
MULTIGARD 5000 FLOW SYSTEM OPERATION
In all cases, the MultiGard 5000 flow system provides sample gas or calibration gas to the
Sensor/Analyzers for analysis or calibration, respectively. Sample or calibration gas flow must
be established to the Sensor/Analyzer for normal operation.
Do not operate the system without ensuring proper flow
on all of the sample points. Flow failures will prevent
the proper analysis of gas samples and a trouble
indication will occur. Failure to restore the sample
point flow immediately may result in a hazardous
condition.
All MultiGard 5000 Systems require sample line filtration for each of the sample points.
Do not operate the system without providing adequate
sample line filtration for all sample lines. Flow system
damage will occur if dirt, water, or other foreign matter
enters the flow system.
Refer to the flow diagram for the MultiGard 5000 System or to the parts list in the MultiGard
System operator’s manual for sample line filter part numbers and descriptions.
A manual calibration of all Sensor/Analyzers is required before the MultiGard 5000 System is
placed into service. A MultiGard 5000 Manual Calibration screen is provided to aid with manual
calibration. Read the Sensor/Analyzer instruction manual in Section 3 before placing the
MultiGard system in operation.
Manual Calibration functions are described in the MultiGard 5000 Instruction Manual Section
4.1.5, Section 2. Sensor/Analyzer instructions appear in Section 3.
