Modifying, disassembling, or altering the MPX is strictly prohibited. Email: Online chat at IMPORTANT: All repairs and adjustments of the MPX level sensor must be made by the factory.We will issue you an RMA number with instructions. If your MPX level sensor needs repair, contact us via email, phone, or online chat on our website. If the cover becomes damaged or is misplaced, order a replacement immediately.ĭANGER: WARNING - POTENTIAL ELECTROSTATIC CHARGING HAZARD – CLEAN ONLY WITH A DAMP CLOTH Repair Information This will help ensure proper re-installation of the float(s).Īlso, ensure that the housing cover is snuggle secured. If you need to remove the floats(s) from the stem of your MPX, be sure to note the orientation of the float(s) prior to removal. If sediment or other foreign matter becomes trapped between the stem and float(s), detection errors can occur. However, in general, you should periodically inspect your MPX unit to ensure the stem is free of any heavy buildup that might impede the movement of the float(s). Your level sensor is very low maintenance and will need little care as long as it was installed correctly. IMPORTANT: Refer to section 9 for Hazardous Location Wiring. IMPORTANT: For EMI protection, either connect the grounding screw (see section 4) to an earth ground, or ensure that tank mounting of the MPX is grounded. The RST-6001 can only supply ±5 Vdc, not the +12-24 Vdc required by the MPX. Note: An independent +12-24 Vdc power supply is required when using an RST-6001 Modbus Controller. APG Modbus software can be downloaded from Modbus System Wiring with RST-6001 ![]() NOTE: For APG Modbus programming instructions, please see MPX user manual. Note: Earth Ground terminal is factory connected to internal housing ground lug. Warning: - The model MPX-T contains titanium in excess of 7.5% for Group II and care needs to be taken to avoid an ignition hazards due to impact or friction Sensor and System Wiring Diagrams ![]() Remove sticker prior to use.ĭANGER: WARNING - EXPLOSION HAZARD - DO NOT DISCONNECT EQUIPMENT UNLESS POWER HAS BEEN SWITCHED OFF OR THE AREA IS KNOWN TO BE NON-HAZARDOUS Untapered floats will have a sticker or “N” indicating the top of the float. IMPORTANT: Floats must be oriented properly on the stem, or sensor readings will be inaccurate and unreliable. See Modbus System Wiring Diagrams (section 6) for Modbus wiring examples.
