Introduction 

Thank you for selecting a DAISY solution for your hazardous area operator interface 

requirements! 
This manual describes the general procedures for installing and operating DAISY Model 

9016 X-Purge interface systems. The text portion of the manual also includes an overview of 

the theory behind the methods used to make electronic systems safe for hazardous areas. 

Section 9, Specifications, also contains an overview of system specifications, and Section 10 

Drawings, includes mechanical drawings of each unit.

Hazardous Area Safety Methods: Theory of Operation 

2.1

 

Division 1: X-Purge Protection 

X-Purge systems are another option available for Division 1 hazardous areas. The 

installation of an X-Purge system on an enclosure in a Division 1 area renders the area 

within the enclosure to an essentially non-rated environment. Thus, normally rated 

equipment may be installed within the enclosure (within reasonable limits, such as 

complying with temperature and power restrictions). 
An X-Purge system is fully automated. The system not only provides the protective 

purge and maintains positive pressure, but it also automatically controls the 

connection and disconnection of power supplies and signal paths. A well-designed X-

Purge system also automatically control flow rates, internal pressure regulation, purge 

timing, and switching of states between purge flow and normal operation. DAISY X-

Purge controls provide all of these features. 
X-Purge controls must also satisfy the FM 3620: 4.2 specifications. DAISY X-Purged 

equipment has also been validated by Factory Mutual as meeting these requirements.
