  • Page 4: Mechanical Installation

    Mechanical Installation Choose a mounting position as far away as possible from sources of electrical noise such as motors, generators, fluorescent lights, high voltage cables/bus bars etc. An IP65 or IP67 access cover which may be installed on the panel and surrounds is available as an option to be used when mounting the instrument in damp/dusty positions.

  • Page 5: Electrical Installation

    Electrical installation Electrical installation The PM4 Panel Meter is designed for continuous operation and no power switch is fitted to the unit. It is recommended that an external switch and fuse be provided to allow the unit to be removed for servicing. The plug in, screw type, terminal blocks allow for power supply wires of up to 2.5mm to be fitted.

    Explanation of functions The PM4 setup and calibration functions are configured through a push button sequence. The three push buttons located at the rear of the instrument (also at the front on some display options) are used to alter settings. Two basic access modes are available: FUNC mode (simple push button sequence) allows access to commonly set up functions such as alarm setpoints.

For example the bargraph scale may be indicating percentage fill of a tank whilst the 7 segment display is indicating actual process units. To set bargraph low level go to the bAr_ function and use the ^ or v push buttons to set the value required then press F to accept this value.

  • Page 35: Scaled Inputs

    Scaled inputs This chapter covers the scaled binary/Gray/BCD code facility of the PM4-BC display (note for BCD inputs the bcd COde function must be set to 0 if scaling is required). This facility allows the display value for an input to be scaled by a two point scaling i.e. the display does not need to follow normal binary or Gray code values.

Press the F button the message CAL End followed by the next function will be seen. Press and release the F button until the message FUNC End is seen and the display moves back to normal display mode.

  • Page 37: Weighted Input Operation

    3.12 for electrical connection details. This chapter describes the special weighted digital input mode available on the PM4-BC. To operate in this mode the SEt INPt function must be set to d.inP. The weighted digital input mode allows up to 8 inputs to be given weighted values, these weighted values are added together for each active input.

    Specifications Technical specifications Input data: 20 input lines for BCD, binary or Gray code addressed and strobed inputs can be used to give up to 8 digit display or special weighted digital input (up to 8 inputs). For BCD inputs four of the 20 input bits can be assigned for use as remote decimal point and display hold if required.
