Hazardous Area Oxymitter DR

Instruction Manual

IB-106-340CDR Original Issue January, 2002

6.If the system has an abrasive shield, check the dust seal gaskets. The joints in the two gaskets must be staggered 180°. Also, make sure the gaskets are in the hub grooves as the Hazardous Area Oxymitter DR slides into the 15° chamfer in the abrasive shield.

NOTE

If process temperatures will exceed 200°C (392°F), use anti-seize com- pound on stud threads to ease future removal of Oxymitter DR.

7.Insert probe through the opening in the mounting flange and bolt the unit to the flange.

NOTE

To maintain CE compliance, ensure a good connection exists between the mounting plate studs or earthing screws on termination housing and earth.

8.Ensure the Hazardous Area Oxymitter DR is properly earthed by way of both internal and external points.

9.If insulation is being removed to access the duct work for Hazardous Area Oxymitter DR mounting, make sure the insulation is replaced afterward (Figure 2-6).

10.Ensure the installation does not obscure the messages on either housing cover.

2-2 ELECTRICAL INSTALLATION

All wiring must conform to local and national codes.

Disconnect and lock out power before
connecting the unit to the power	2
supply.

Install all protective equipment covers and safety ground leads after installa- tion. Failure to install covers and ground leads could result in serious injury or death.

To meet the Safety Requirements of IEC 1010 (EC requirement), and ensure safe operation of this equipment, con- nection to the main electrical power supply must be made through a circuit breaker (min 10 A) which will discon- nect all current-carrying conductors during a fault situation. This circuit breaker should also include a me- chanically operated isolating switch. If not, then another external means of disconnecting the supply from the equipment should be located close by. Circuit breakers or switches must comply with a recognized standard such as IEC 947.

The Hazardous Area Oxymitter DR and probe abrasive shield are heavy. Use proper lifting and carrying procedures to avoid personal injury.

a.Remove screw (11, Figure 4-1),captive washer (13), and cover lock (12). Remove left housing cover (10).
