Distillation Process Analyzer DPA-4.5 Maintenance Restoring the plug connections • Plug the connectors 1–3 back together. Figure 10.10: Plugging in the distillation flask heater and temperature sensor • Close the measuring unit box. • Restarting operation For the steps to be taken after maintenance work, please refer to page 151.
Distillation Process Analyzer DPA-4.5 Maintenance 10.5.6 Cleaning the flame arresters All supply and drain lines to and from non-failsafe pipeline systems in the Ex d box are equipped with flame arresters (see page 62). The box provides explosion pressure for the measuring unit by the pressure-resistant enclosure ignition protection Ex d (see page 29) only in combination with the flame arresters.

Distillation Process Analyzer DPA-4.5 Maintenance Overview Flame filter right (R) Outer box Flame filter left (L) O-ring Ribbed ring Inner box Figure 10.3: Flame arrester design. Three flame filters are installed. The middle flame filter (4) is equipped with gaps with a right-hand angular offset, and the two other flame filters (2) are equipped with gaps with a left-hand angular offset.
Page 143
Distillation Process Analyzer DPA-4.5 Maintenance Removing the flame arresters To clean the flame arrester, unscrew the inner box (7) from of the outer box (1). The outer box remains firmly screwed onto the Ex d box. • Disconnect the flame arrester from the pipeline. To do this, unscrew the Swagelok screw connection and the screw pipe connection on the inner box of the flame arrester.

Distillation Process Analyzer DPA-4.5 Maintenance Assembling the flame arresters WARNING Danger of explosions due to incorrectly mounted flame arresters The Ex d box does not provide any explosion protection if the flame arresters are mounted incorrectly. For this reason: – Make sure that all three flame filters are in use.
Distillation Process Analyzer DPA-4.5 Maintenance 10.5.7 Replacing the heating cartridges and/or flask bottom temperature sensor If one heating cartridge is defective, the whole set has to be replaced. The heating cartridges are easier to remove if the flask bottom temperature sensor is removed first. If this is also defective, you can replace it at the same time.
