5.
Do not substitute components. Substitution of components may impair the intrinsic safety rating.
6.
Do not operate the sensor outside of the stated operating temperature limits.
7.
Do not operate the sensor outside the stated operating limits for voltage supply.
8.
These sensors meet ATEX standards EN60079-0:2012. EN60079-1:2007 and EN60079-11:2012.
9.
These sensors have a maximum safe location voltage of Um=30V.
10.
These sensors pass dielectric strength of 500VRMS between circuit and enclosure for a minimum of 1
minute at a maximum test current of 5mA.
11.
The CXT-IR must only use IR cell model 371-IR1II1-000. No other cell shall be used.
12.
The CXT-IR is only to be used with Detcon P/N 360-026500-000 batteries (Tadiran Model TL-5920).
The battery holder utilizes three of these batteries in series to operate the sensor.
13.
For North American use only, the CXT-IR may use Detcon P/N 360-TL5930-000 batteries (Tadiran
Model TL-5930). The battery holder utilizes 5 of these D cell batteries in series to operate the sensor.
14.
For North American use only, the CXT-IR may use Detcon P/N 360-3S6P00-000 (2200mAh) or P/N
360-3SP00-290 (2900mAh) rechargeable Lithium batteries.
15.
The CXT-IR contains FCC ID U90-RF200 and IC 7084A-RF200.
16.
The CXT-IR complies with FCC Maximum Permissible Exposure (MPE) requirements when used with
an approved antenna and the antenna is at least 20cm away from the user. Use of the product closer than
20cm may exceed the MPE limits. Use of any antenna other than the approved antennas will invalidate
the certification of the product.
17.
The CXT-IR complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.
WARNING:
CSA certification does not include wireless communication or Modbus used for combustible gas
performance. The wireless communication or Modbus may only be used for data collection or
record keeping with regard to combustible gas detection. Gas indication and alarm functions for
performance are only permitted locally by the detector.
2.2
Sensor Placement
Selection of sensor location is critical to the overall safe performance of the product. Six factors play an
important role in selection of sensor locations:
•
Density of the gas to be detected
•
Most probable leak sources within the industrial process
•
Ventilation or prevailing wind conditions
•
Personnel exposure
•
Placement of transmitting antenna
•
Maintenance access
