APG SENSORS FREE
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 SENSORS SOFTWARE
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.
For EMI protection, either connect the grounding screw (see Dimensions section 4) to an earth ground, or ensure that tank mounting of MPX is grounded. Use crimped ferrules on wires, if possible. Fittings must be UUCSA Listed for CSA installation. Feed system wires into MPX through 3/4″ NPT conduit openings. For sensors with float stops, refer to the assembly drawing included with the sensor for float stop installation locations. If the floats do not fit, mount them on the stem from inside the vessel being monitored. If your sensor’s stem and floats fit through the mounting hole, carefully lower the assembly into the vessel, then secure the sensor to the vessel. Faulty installation will invalidate all safety approvals and ratings. IMPORTANT: MPX level sensor MUST be installed according to drawing 9003468 (Hazardous drawing 9003468 (Hazardous Installation and Non-Inc endive Wiring Drawing) in section 9 to meet listed approvals. MPX-R and MPX-T floats are typically installed by customer. The float(s) is/are oriented properly on the stem (See Figure 5.1 below). If the float(s) does/do not fit, it/they must be mounted on the stem from inside the vessel being monitored. The float(s) fit through the mounting hole. The probe is not exposed to excessive vibration. No ignition hazards exist due to impact or friction with the titanium stem. The medium is free from metallic substances and other foreign matter. The probe is located away from strong magnetic fields, such as those produced by motors, transformers, solenoid valves, etc. Ample space for maintenance and inspection. No chemicals incompatible with Titanium Grade 2 for MPX-T. No chemical corrosive to stainless steel (such as NH3, SO2, Cl2, etc.) for MPX-R. IEC-664-1 Conductive Pollution Degree 1 or 2. The MPX should be installed in an area–indoors or outdoors–which meets the following conditions: IMPORTANT: WARNING - A SEAL SHALL BE INSTALLED WITHIN 18 inches OF THE ENCLOSURE ĭANGER: OPEN CIRCUIT BEFORE REMOVING COVER or KEEP COVER TIGHT WHILE CIRCUITS ARE ALIVE ĭANGER: WARNING - EXPLOSION HAZARD - SUBSTITUTION OF COMPONENTS MAY IMPAIR SUITABILITY FOR CLASS I, DIVISION 2 Installation Guidelines & Instructions
