Special Conditions for Safe Use
• Do not open the instrument when energized.
• For dust applications the installation conditions according to EN 60079-31 has to be considered.
• Intensive electrostatic charging processes have to be prevented on the instrument label.
• The joint widths of the flameproof joint of this apparatus are in parts longer, and its gaps are in parts
shorter than the values of Table 2 of EN 60079-1:2014. For maintenance or repair contact the
manufacturer.
In case of using the PrimaX Ex-Sensor, the complete device type PrimaX P is in accordance to
temperature class T6/T85°C, ambient temperature range -40°C ≤ Ta ≤ +40°C or to temperature class
T4/T130°C, ambient temperature range -40°C ≤ Ta ≤ +70°C
In case of using the PrimaX Ox-Tox-Sensor, the complete device type PrimaX P is in accordance to
temperature class T4/T130°C, ambient temperature range -40°C ≤ Ta ≤ +70°C
Avoid electrostatic charge on the temporary used calibration cap when used for calibration.
Cable gland
• M25 x 1,5;Torque 8 -12 Nm; only ATEX certified versions for gas and dust shall be used.
• NPT ¾"- 14; fixture with 2 layer PTFE sealing tape or according to the instructions of the NPT
supplier; when removed, new PTFE sealing has to be used after reinstalling; only ATEX certified
versions for gas and dust shall be used.
The HART-interface is subject of this type examination certificate only for the purpose of maintenance and
parametrization.
When the HART-/ relay module is used the alarm shall be configured latching.
If a device with a combustible sensor is exposed to vibrations , calibration shall be done in sufficient short
intervals until it is verified that the device is not affected by the vibration stress.
After exposure of gas above the measuring range, the sensor has to be immediately calibrated/adjusted,
independent of the calibration interval. In the case of an adjustment the sensitivity of the sensor has to be
rechecked again after 24 hours.
