WARNINGS
Access to the interior of the transmitter, when carrying out any work, must only be conducted by trained
personnel.
The transmitter has a potential electrostatic charging hazard. To minimize the risk of electrostatic
discharge:
• Ground the transmitter adequately
• Install the transmitter in a manner that will prevent accidental electrostatic discharges, e.g. ensure
that objects do not rub against the housing etc.
• Clean the enclosure with a damp cloth when necessary
Care should be taken when removing and refitting the Sensepoint XCD plug-in Sensor.
Cartridge to the Sensor Socket so that damage to the connection pins can be avoided.
Before carrying out any work ensure local regulations and site procedures are followed. Appropriate
standards must be followed to maintain the overall certification of the sensor and transmitter.
To reduce the risk of ignition of hazardous atmosphere, de-classify the area or disconnect the equipment
from the supply circuit before opening the transmitter enclosure. Keep assembly tightly closed during
operation.
Never attempt to open a junction box/enclosure or replace/refit the sensor in potentially
hazardous atmospheres.
Take care when handling sensors as they may contain corrosive solutions.
Do not tamper with or in any way disassemble the sensor.
Do not expose to temperatures outside the recommended ranges.
Do not expose sensors under storage conditions to organic solvents or flammable liquids.
At the end of their working life, replacement electrochemical sensors for oxygen and toxic gas must be
disposed of in an environmentally safe manner. Disposal should be according to local waste management
requirements and environmental legislation.
Alternatively, old replaceable sensors may be securely packaged and returned to Honeywell Analytics clearly
marked for environmental disposal.
Electrochemical sensors should NOT be incinerated as this action may cause the cell to emit toxic fumes.
Honeywell Analytics recommends that gas detectors are tested and re-calibrated on a six-monthly basis,
or according to site practice. For remote Flammable or Toxic sensors used with the XCD Transmitter,
refer to the individual sensor manuals for specific recommended calibration periods. If a toxic sensor is
exposed to a gas concentration significantly above the measuring range, it shall be calibrated as soon
as possible afterwards.
