1. INTRODUCTION

This series of panel instruments is a versatile, cost effective solution to a wide variety of monitoring and control applications. These instruments are easily set to produce an accurate display of temperature, pressure, flow, weight, voltage or current. Front panel push-button or RS-232/RS-485 setup allows the user to customize the unit for a specific application. Digital scaling of zero and span provides direct readout in engineering units. Concurrent Slope ( Pat 5,262,780) is a new method of analog-to-digital conversion that provides 60 conversions per second ( 50 for 50 Hz operation ) while integrating over a full cycle of the line for maximum noise rejection. Self calibration cycles reduce the average reading rate to 56 per second ( 47 for 50 Hz ). This fast read rate provides an accurate display of peak signal input and quick response in control applications. The adaptive auto filter automatically supplies a time constant compatible with the signal noise level. This ensures stable displayed readings and outputs while responding rapidly to changes of the input signal that exceed a selected threshold value. Selective security lockout of the front panel setup protects against accidental changes to the meter. The instrument uses a lightweight, high-efficiency switching power supply operating from AC or DC voltages. The meter can be powered worldwide without changes to the supply. An optional low voltage supply operates on 9 to 37 Vdc from batteries or 8 to 28 Vac from sources such as 400 Hz aircraft power. Both supplies have isolated 5, 10, and 24 Vdc excitation outputs to power transducers. The NEMA 4 (IP65) 1/8 DIN case is made of high impact, 94V-0 UL-rated plastic. Mounting is from the front of the panel and requires less than 110 mm behind the panel. All wiring is by removable plugs conforming to IEC950 safety standards. All output options are isolated from meter and power ground by 250 Vac minimum.

The extended DPM is capable of linearizing a nonlinear input signal such as a thermistor, gallons of liquid in a irregularly shaped tank, or altitude. Up to 240 points may be linearized by a computer program that stores the parameters via RS232 into permanent nonvolatile memory. The meter is also capable of measuring rate of change. The level of a tank is measured and the difference between readings determines the flow rate in or out of the tank.

The dual setpoints have two form C ( 10 A @ 250 Vac ) relays or solid state relay outputs for alarm and control capabilities. Either setpoint may be latching or nonlatching and separately configured to be energized above or below the setpoint, as deviation alarms, or in a fail-safe mode. Additionally, outputs may also be selected to operate from the filtered signal to reduce relay chatter or from the unfiltered signal for fast response. Snubber circuits, programmable relay switching time delay and selectable hysteresis extend relay contact life.

Isolation of the 4 to 20 mA and 0 to +10 V analog outputs eliminates ground loop problems. The output may be scaled by front panel push-buttons or RS-232/RS-485. For thermocouples and RTD’s, the output is linearized. The 4 to 20 mA output will drive up to an 600 Ohm load with 12 V compliance

The meter offers RS232 or RS485 bidirectional communications or parallel, 3-state BCD output to interface with computers, PLC’s or other digital devices. IBM PC compatible software is available for programming the unit by the RS232 and RS-485 interfaces.

2. RECEIVING AND UNPACKING

Your meter was carefully tested and inspected prior to shipment. Should the meter be damaged in shipment, notify the freight carrier immediately. In the event the meter is not configured as ordered or the unit is inoperable, return the unit to the place of purchase for repair or replacement. Please include a detailed description of the problem.

3. SAFETY CONSIDERATIONS

Warning : The use of this equipment in a manner other than specified may impair the

protection of the device and subject the user to a hazard. Visually inspect the unit for signs of damage. If the unit is damaged, do not attempt to

operate. This unit must be powered with AC ( mains ) from 85 to 264 Vac (90 to 370 Vdc) with the high

voltage power supply option or 8 to 28 Vac (9 to 37 Vdc) with the low voltage power supply option. Verify that the proper power option is installed for the power to be used.

This meter has no AC ( mains ) switch; it will be in operation as soon as power is connected. Caution: The 85 to 264 Vac (90 to 370 Vdc) mains connector (J1 Pins 1-3) is color coded

Light Blue to differentiate it from other input and output connectors. The 8 to 28 Vac (9 to 37 Vdc) mains connector is not color coded because these voltages are not considered hazardous.

Do not make signal wiring changes or connections when power is applied to the instrument. Make signal connections before power is applied and, if reconnection is required, disconnect the AC ( mains ) power before such wiring is attempted.

To prevent electrical or fire hazard, do not expose the instrument to excessive moisture. Do not operate the instrument in the presence of flammable gases or fumes; such an

environment constitutes a definite safety hazard. This meter is designed to be mounted in a metal panel.

Verify the panel cutout dimensions and mount according to instructions.

MENU KEY

The menu key steps through the various meter parameters that may be selected. These menu items may be “locked out” from front panel selection by software and hardware.

PEAK DISPLAY KEY (DIGIT SELECT)

In the Operating Mode, pressing the Peak Display Key causes the peak value of the input signal to be displayed. Pressing the key again returns the display to the present value. In the Menu Mode , the Digit Select Key (Peak Display Key) is used to select input type and decimal point or to select one of the five display digits for programming. In the main menu, pressing the Digit Select Key causes the value or code that is stored for that menu item to be displayed and the left hand digit flashes. Each time the key is pressed, the next digit to the right will flash. The value of the flashing digit may be changed using the Value Select Key. In the Alarm Mode, pressing the Digit Select Key causes the most significant digit of the displayed setpoint value to flash. Digits are then selected the same as in the Menu Mode.

RESET KEY (VALUE SELECT)

In the Operating Mode, holding the Reset Key depressed and pressing any other key causes a reset to occur. The Menu Key resets all meter functions, the Alarm Key resets any alarm conditions and the Peak Display Key resets the peak value to present value. In the Menu Mode or Alarm Mode, the Value Select Key ( Reset Key) sets the value of the flashing digit. Each time the key is pressed, the value increases by one. Holding the key down causes the digit to automatically step through the numbers.

ALARM KEY (REVERSE MENU)

In the Operating Mode, pressing the Alarm Key displays the setpoint of Alarm 1 and then Alarm 2. These values may be changed using the Digit Select Key and the Value Select Key. In the Menu Mode, pressing the Alarm Key steps the display backward through the menu.

12.2 MENU SELECTION

Display in engineering units is most easily programmed using the coordinates of 2 points. There are two methods. The first is to enter the 4 values (low signal input, desired reading at the low signal input, high signal input, and desired reading at the high signal input) directly via the front panel pushbuttons or the RS232 interface. The second method is to have the meter read the signal input at a known low value and store that reading as the low in and read a known high signal value and store that value as high in. The low and high known values are entered as the lo rd and hi rd. An example of using the reading the input method of coordinates of 2 points is shown for the load cell meter, Section 17. Selecting the reading method (menu item "config" digit 2 set to 1) overides either method of scaling selected in "setup". The following example is the 2 coordinate method of directly entering the 4 values.

-22-

To set up the range using coordinates of 2 points, values for low signal input, low display, high signal input and high display are entered. The following example uses this scaling method. Signal input is 4 to 20mA and displayed value is 000.00 (at 4mA) to 100.00 (at 20mA). When setting up the meter, it may be necessary to enable some menu items. See Section 9 for further information.

This section describes how to remove the error caused by lead resistance in a 2-wire RTD. Ambient temperature changes will cause some error in the readings; the higher the lead resistance, the greater the error. When performing this procedure, the leads should be shorted together as close as possible to the RTD. This step is not necessary when using 3- or 4-wire RTD's since lead resistance compensation is automatic in the meter. When setting up the meter, it may be necessary to enable some of the menu items.

This section provides basic setup instructions for true RMS voltage or current monitoring. An RMS signal conditioner is required. Some menu items, such as leading zero blanking, display filtering, etc., are not discussed in this section and have been set to the most commonly used values. Should these items require change, refer to section 10 for selection information. For configuration of optional boards, see the appropriate section elsewhere in the manual.

16. 2 MENU SELECTION

Whenever the scale factor is 1.0 and offset is zero, the meter displays a direct readout of the signal input in (milli)volts or (milli)amperes. In the following example, the meter is configured for a full scale display of 0 to 20V or 0 to 20mA equals 20.000. Other ranges follow the same setup format. Note that the decimal point selection does not affect the displayed value. A full scale value of 20000 may be displayed as 20.000 Volts or 20000 millivolts. When an external shunt or current transformer is used to monitor current, the appropriate scale factor must be entered. A 5A CT input to the meter displays 20000 (2000 when 3 1/2 digit is selected). For an 800 Amp CT, divide 8000 (desired full scale display with .1 Amp resolution) by 20000 (full scale when the scale factor is 1.0) for the correct scale factor. Enter .4 as a scale factor. During setup, it may be necessary to enable some menu items that are locked out. See Section 9 for further information.

17.2 MENU SELECTION

To scale the meter using the reading method of coordinates of 2 points, the low signal input and high signal input are read directly by the meter and are stored as Lo in and Hi in. For example, the full scale range of a load cell is 500 pounds and has an output of 2mV/V. With 10V excitation, the full scale range of 20mV selected. The resolution is .01 pounds. With no weight on the scale, the meter should read 0.00 and with a 500 pound weight on the scale the meter should display

500.00 pounds. With no weight on the scale, press the menu key to select Lo inand press the digit select key. The meter will take readings and display the millivolt value of the input signal. Pressing the value select key will store this reading as Lo in. Press the menu key to select Hi in, place the 500 pound weight on the scale and repeat the procedure the same as for Lo in. Press the menu key to select lo rd (Low reading) and enter 000.00, then press the menu key to select Hi rd (High reading) and enter 500.00. Advantages of this method are accuracy, since reading the value corrects for any error in the transducer, and ease of recalibration. To recalibrate the meter, take readings at 0 and 500 pounds, Lo rd and Hi rd do not need to be reentered. If a 500 lb. weight was not available, the same result can be achieved by using any known weight. During setup, it may be necessary to enable some menu items. See Section 9 for further information. See Section 12, Process Meters, for an example scaling by direct entry of the input values.

18.3 BAND DEVIATION

When deviation is selected from the setup menu, a value is entered for the amount of deviation required. This value represents the number of counts at which the relay will be energized above and below the setpoint. For example, if the setpoint is set to 10,000 and a deviation value of 200 was entered, the relay will activate below 9800 and above 10,200.

18.4 HYSTERESIS

When hysteresis is selected from the setup menu, a value is entered for the amount of hysteresis required. This value represents the number of counts at which the relay will be energized above and deenergized below the setpoint. For example, if the setpoint is set to 10,000 and a hysteresis value of 200 was entered, the relay will activate at 10200 and deactivate at 9800.

19. ANALOG OUTPUT

The analog output option provides a 0 to 20mA and a 0 to 10Vdc linear signal derived from the displayed reading. The low signal output and high signal output may be set to equal any displayed value. Although both outputs are available, only one is calibrated to specifications. The other output is accurate to +/-1% of the displayed value typical (2%max).

19. 1 4 TO 20MA OUTPUT SCALING

The output is scaled by selecting a displayed value for the low signal output and a displayed value for the high signal output. For a current output, the low value is 0mA and the high output is 20mA. To scale a signal for 4 to 20 mA, the following procedure must be used:

1. Desired display value for 20mA - Desired display value for 4mA = Display span

2. Display span / 4 = Offset value

3. Desired display value for 4mA - Offset value = An Lo

4. An Hi = Desired display value for 20mA

19. 2 ANALOG OUTPUT SETUP SOFTWARE

The following menu items are accessible only with an Analog Output option installed and appropriate lockouts enabled. See Section 9 for further information. Setup Example: 4mA to 20mA out = 5000 counts to 15000 counts (See Section 19.1).

24. CALIBRATION

All ranges of the meter have been digitally calibrated at the factory prior to shipment. The calibration equipment is certified to NIST standards. Calibration constants are stored in nonvolatile memory in EEPROM on the signal conditioner. This eliminates much of the analog circuitry that causes drift and provides superior long term accuracy and stability.

Since the calibration is stored on the signal conditioner and analog output boards, all boards may be mixed and interchanged without requiring recalibration. If recalibration is required, the meter may be returned to the factory or any authorized distributor.

For the customer requiring on site calibration, an RS-232 or RS-485 option must be installed to perform the calibration. The interface card may be temporarily installed and then removed upon completion of calibration. Step-by-step instructions for calibration and the equipment required is available from the factory.
