    NOTE: For Safety Instrumented Systems usage, it is assumed that Table 1 the 4-20 mA output is used as the primary safety variable. JUPITER JM4 Model Number The analog output for the Model JM4 meets the NAMUR NE 43 standard (3.8 mA to 20.5 mA usable). The transmitter...

  • Page 4: Level Measuring System

    • The only unsafe mode is when the unit is reading an incorrect Unit level within the 4–20 mA range (> ±2% deviation). • MAGNETROL defines a safe failure as one in which the 4–20 mA current is driven out of range (i.e., less than 3.8 mA or greater than 21.5 mA).

    Overvoltage Category II is a local level, covering appliances, por- table equipment, etc., with smaller, transient overvoltages than those characteristic of Overvoltage Category III. This category applies from the wall plug to the power-supply isolation barrier (transformer). As the typical plant environment is Overvoltage Category II, most equipment evaluated to the requirements of IEC/EN 61010 are considered to belong in that classification.

    5.1.2 Environmental Refer to Installation and Operating Manual ORI-650 for envi- ronmental limitations. 5.1.2.1 Storage The device should be stored in its original shipping box and not be subjected to temperatures outside the storage temperature range of -50 to +185 °F (-46 to +85 °C). Installation Refer to the Model JM4 Installation and Operating Manual ORI-650 for complete installation instructions.

  • Page 7: Configuration

    5.5.2 Configuration Ensure the parameters have been properly configured for the application and probe. Special consideration should be given to the following configuration parameters: FAULT: DO NOT choose HOLD for this parameter as a Fault will not be annunciated on the current loop. BLOCKING DISTANCE: This value MUST be zero for SIL applications.

    5.8.2 Troubleshooting Report all failures to the MAGNETROL technical support department. Refer to the Model JM4 Installation and Operating Manual ORI-650 for troubleshooting device errors. • The SIL Proof Test provides a reliable indication when mainte- nance is required. • Firmware can be upgraded only by factory personnel.
  • Page 9 Step Action Bypass the PLC or take other action to avoid a false trip. Remove power from the Unit. (This clears any potential soft RAM errors.) Inspect the Unit in detail outside and inside for physical damage or evidence of environmental or process leaks. a.) Inspect the exterior of the unit housing.
  • Page 10 Step Action Use the “DIAGNOSTICS” menu to observe the present Echo Curve and document typical per- formance values. Confirm that the ECHO Waveform is normal. The ECHO curve is dependent on the probe used and the level of the process on the probe. It is recommended that a typical ECHO curve be saved at commissioning.

    It is the responsibility of the end user to maintain and operate the Model JM4-511x-xxx per manufacturer’s instructions. Fur- thermore, regular inspection should indicate that all components are clean and free from damage. When plant experience indicates a shorter lifetime than indicat- ed here, the number based on plant experience should be used.
