  • Page 45: Section 8 Methods For Scaling The Meter To Display In

    8. Methods for Scaling the Meter to Display in Engineering Units 8.1 INTRODUCTION This section is for scaling the meter to read in desired engineering units. This meter is capable of producing any engineering units up to 6 digits regardless of decimal point. Even though this is a strain gauge input meter it is capable of working with high voltage, current and potentiometric inputs.

  • Page 46: Figure 8-1 S3 And S4 Main Board Jumper Positions

    The two most common methods of scaling, Method I scaling without simulating a known load, and Method II scaling by simu- lating known loads will be demonstrated. Sometimes end users simulate known voltages instead of known physical standards (pressures); this is covered in Method II. A third method is for a unique case where you are scaling with a known load and you want the display to have 3 or more decimal places.

SP3 and SP4 are often used as ALarm 1 and ALarm 2, because they have single-sided hysteresis and can be configured for latching action.

    RS-232 or RS-485 Option Board 15.2 FRONT-PANEL PUSHBUTTON CONFIGURATION Setup configuration can be accomplished via the front panel buttons or via your computer if you use the configuration setup program. If you are going to use a computer, your choices include “AUTO SET” or “MANUAL SET” for establishing communication with your meter.

  • Page 156: Section 16 External Control Lines

    External Control Lines EXTERNAL CONTROL LINES P2, the 20-pin connector at the rear of the main board, connects to the setpoint transistor collectors and permits remote control of significant meter features. The meter case label gives the names (abbreviated functions) of each of the twenty pins of P2, the center-bottom connector.

    External Control Lines 16.6 PUSH TO CAL (PIN 6) The Push To Cal feature is only available for the Strain Gage meter and the Universal meter when configured for the BRIDGE mode. This feature allows you to connect an external calibration resistor to P2-6 and P2-14 at the rear of the meter.

    External Control Lines 16.13 PUSH TO CAL (PIN 14) See Section 16.6. 16.14 +V EXT (PIN 15) This is the pin on which to bring in isolated external 5 to 30 V to power the snubbing diodes of the four setpoint/alarm open-collector transistors. 16.15 SP1 (PIN 16) The open-collector of the first setpoint transistor (can carry 150 mA).

    Troubleshooting TROUBLESHOOTING - DISPLAY MESSAGES AND TROUBLESHOOTING GUIDE A flashing alpha-numeric message in the display generally indicates an incorrect combination of jumpers and/or configuration values. 17.1 ERROR MODE MESSAGES 17.1.1 Flashing “999999” (Numerical Overflow) The maximum number of counts in the display cannot exceed –99999 or 999999.

  • Page 160: Flashing "-Open" (Open Sensor Indication)

    Troubleshooting 17.1.7 Flashing “-OPEN” (Open Sensor Indication) Coupled with the proper jumper selection, a “-OPEN” indicates the input is below the bottom limit of the range selected. 17.1.8 Flashing “I OVSC” (Input Overscale) This display occurs when the input scale and/or offset applied to the input signal causes the display to go into a numerical overflow.
  • Page 161 Troubleshooting “ERR 02” POSSIBLE CAUSE: Active decimal (RDG.2) has been selected and/or DEC PT (decimal point) position has been moved one or more places to the left driving the programmed Setpoint value into numerical overflow. TO CORRECT: Display will flash “ERR 02” message for a short period of time, then automatically correct the setpoint’s decimal point position and move to the next menu item.
  • Page 162 Troubleshooting “I OVSC” POSSIBLE CAUSE: The input scale and/or offset values chosen are large enough to drive the display into numerical overflow. TO CORRECT: Reduce the input and/or the input scaling/offset. Refer to “IN.SC.OF” in Section 9.2.5. “R OVSC” POSSIBLE CAUSE: The reading scale and/or offset values chosen are large enough to drive the display into numerical over- flow.
