8.1.6
Assembly
To perform maintenance and troubleshooting work on the assembly, please refer to the assembly
Operating Instructions. These Operating Instructions contain information on assembling and
disassembling, replacing the sensor and seal, resistance and information on spare parts and
accessories.
Weekly inspections (recommended timeframe)
• Check that the upper assembly section is sealed against compressed air and is not mechanically
damaged.
• Check that the process connection is airtight and sealed towards the process and is not
mechanically damaged.
• Check the compressed air pipes and connections for leaks and mechanical damage.
Annual inspections (recommended timeframe)
• Clean the assembly externally as required. To replace seals, the assembly must be clean, dry and,
if necessary, decontaminated.
• In the event of inductive feedback: Check the switching distance and adjust it if necessary.
• Replace the non-wetted seals (recommended: Where necessary, at least 1x year).
• Replace the wetted seals (at least 1x year, no further recommendations possible as depends
primarily on the process, material and frequency of use of the assembly).
• After the maintenance tasks, carry out the following end test:
– Assembly moves to the Measuring and Service position?
– Service and Measure feedback signals available? (Control via the CPM153 status messages)
– Process connection and compressed air connections tight?
– Does the meter display plausible values?
Replacement of the sealing elements is dependent on the type of assembly. Instructions for
replacement is contained in the appropriate service kit. The requisite service kit can be found in the
Operating Instructions on your assembly or in the "Cleanfit retractable assembly" special
documentation (SD096C/07/a2).
8.1.7
Cables, connections and power supply lines
Weekly inspections (recommended timeframe)
Check the tightness of:
• Compressed air hoses and connections
• Pressurized water hoses and connections
• Hoses and connections of buffer and cleaner tanks
• Multihose connections at control unit and assembly
Monthly inspections (recommended timeframe)
• If the assembly is located in a humid/wet environment or outdoors and you are using analog
sensors, check the sensor plug-in head for leaks or moisture.
• Check that the sensor cables, particularly the external insulation, are in a sound condition. You
must replace sensor cables that have become wet inside! Only drying is not sufficient!
• Check cable connections for leaks.
Half-yearly inspections (recommended timeframe)
• Check whether the inner compartment and the circuit boards in Mycom S are clean, dry and free
from corrosion.
If not:
– Clean and dry the inner compartment and circuit boards.
– In the event of corrosion, replace the affected circuit boards where necessary.
– Check that the seals and couplings are leaktight and in a sound condition.
• Tighten the terminals in Mycom S.
• If the assembly is located in a dry environment and you are using analog sensors, check the sensor
plug-in head for leaks or moisture.
