Dimensions

IMPORTANT: WARNING — A SEAL SHALL BE INSTALLED WITHIN 18 inches OF THE ENCLOSURE;
DANGER: OPEN CIRCUIT BEFORE REMOVING COVER or KEEP COVER TIGHT WHILE CIRCUITS ARE ALIVE;
DANGER: WARNING — EXPLOSION HAZARD — SUBSTITUTION OF COMPONENTS MAY IMPAIR SUITABILITY FOR CLASS I, DIVISION 2;
DANGER: WARNING — EXPLOSION HAZARD — DO NOT DISCONNECT EQUIPMENT UNLESS POWER HAS BEEN SWITCHED OFF OR THE AREA IS KNOWN TO BE NONHAZARDOUS;
Warning: — The model MPX-T contains titanium over 7.5% for Group II and care needs to be taken to avoid ignition hazards due to impact or friction;

Installation Guidelines & Instructions

The MPX should be installed in an area–indoors or outdoors–that meets the following conditions.
Ambient temperature between -40°C and 85°C (-40°F to +185°F)
Relative humidity up to 100%
Altitude up to 2000 meters (6560 feet)
IEC-664-1 Conductive Pollution Degree 1 or 2
IEC 61010-1 Measurement Category II

No chemical corrosive to stainless steel (such as NH3, SO2, Cl2, etc.) for MPX-R
No chemicals incompatible with Titanium Grade 2 for MPX-T
Ample space for maintenance and inspection

Additional care must be taken to ensure:

The probe is located away from strong magnetic fields, such as those produced by motors, transformers, solenoid valves, etc.
The medium is free from metallic substances and other foreign matter.

No ignition hazards exist due to impact or friction with the titanium stem.
The probe is not exposed to excessive vibration.
The float(s) fit through the mounting hole. 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) is/are oriented properly on the stem (See Figure 5.1 below). MPX-R and MPX-T floats are typically installed by customers.
IMPORTANT: MPX level sensor MUST be installed according to drawing 9003468 (Hazardous Installation and Non-Incendive Wiring Drawing) in section 9 to meet listed approvals.
The faulty installation will invalidate all safety approvals and ratings.

Installation Instructions:

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.
If the floats do not fit, mount them on the stem from inside the vessel being monitored. Then secure the sensor to the vessel.

For sensors with float stops, refer to the assembly drawing included with the sensor for float-stop installation locations.

Electrical Installation Instructions:

Remove the housing cover of your MPX.

Feed system wires into MPX through 3/4” NPT conduit openings. Fittings must be UL/CSA Listed for CSA installation.
Connect wires to MPX terminals. Use crimped ferrules on wires, if possible.
Replace the housing cover.

For EMI protection, either connect the grounding screw (see Dimensions section 4) to an earth ground or ensure that tthe ank mounting of MPX is grounded.
See Modbus System Wiring Diagrams (section 6) for Modbus wiring examples.
IMPORTANT: Floats must be oriented properly on the stem, or sensor readings will be inaccurate and unreliable.

Untapered floats will have a sticker or “N” indicating the top of the float. Remove the sticker before use.

IMPORTANT: For EMI protection, either connect the grounding screw (see section 4) to an earth ground or ensure that tthe mounting of the MPX is grounded.
IMPORTANT: Refer to section 9 for Hazardous Location Wiring.

General Care

Your level sensor is very low maintenance and will need little care as long as it is installed correctly. 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). If sediment or other foreign matter becomes trapped between the stem and float(s), detection errors can occur.
If you need to remove the floats(s) from the stem of your MPX, be sure to note the orientation of the float(s) before removal. This will help ensure proper re-installation of the float(s).
Also, ensure that the housing cover is snuggly secured. If the cover becomes damaged or is misplaced, order a replacement immediately.

DANGER: WARNING — POTENTIAL ELECTROSTATIC CHARGING HAZARD – CLEAN ONLY WITH A DAMP CLOTH.
IMPORTANT: All repairs and adjustments of the MPX level sensor must be made by the factory. Modifying, disassembling, or altering the MPX is strictly prohibited.
