1. INTRODUCTION

The 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 frequency, rate, total, period, time interval, phase, position , flow, etc. Front panel pushbutton 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. A high stability crystal and digital calibration of all ranges eliminates drift associated with potentiometers found in non-microcomputer-based meters. The meter measures the period of the input signal to calculate frequency or rate. This fast read rate provides an accurate display of peak signal input and quick response in control applications. Selectable gate time (10ms to 99s) and adaptive filter ensure stable displayed readings and outputs while responding rapidly to changes of the input signal. Selective security lockout of the front panel setup protects against accidental changes to the meter configuration and simplifies use by the operator. The series uses a lightweight, high-efficiency switching power supply that operates from either AC or DC voltages and complies with safety regulations. 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 24Vdc 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 dual setpoints have two form C ( 10 A @ 250 Vac ) relays or open collector outputs for alarm and control capabilities. Either setpoint may be latching or nonlatching and may be separately configured to be energized above or below the setpoint or in a fail-safe mode. 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 and programmable relay switching time delay 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 pushbuttons or RS-232/RS-485. For square root and custom curves, the output is linearized. Depending on the application, the analog output may be selected to operate from the filtered or unfiltered signal input. The 4 to 20 mA output will drive up to an 800 Ohm load with 16 V compliance

The meter offers RS-232 or RS-485 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 of the unit by the RS-232 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.

OPERATING MODE

The meter is in normal operation and the input signal value is displayed.

MENU MODE

The meter display and outputs do not respond to the input signal and alarm relays are deenergized.

MENU KEY

The menu key changes the meter from the operating mode to the menu mode and 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. If the Displayed Item Key (Reset Key) is pushed and released without depressing another button (and if the

-8-

meter is configured to display more than 1 item), display item #2 is displayed and the displayed item indicator lights. Repeating this selects display item #3 and displayed item indicator flashes. 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.

9. SETTING MENU LOCKOUTS

For security and ease of operation, any or all program menu items may be disabled. Each function to be disabled is set to "1" in the menu items, " Loc 1"," Loc 2", "Loc 3" or "Loc 4". These lockout menu items may in turn be "locked-out" by installing an internal hardware shorting jumper. With the jumper installed, the operator has access only to enabled menu items.

11.1 SETTING JUMPERS FOR INPUT SIGNAL LEVELS

Channel B

Channel A

Minimum High and Low Input Signal Levels

The jumper settings for Channel A (A2 & A3) and Channel B (B2 & B3) are selected depending on the input amplitude. The input signal voltage must exceed the high and low threshold per the following table or the meter will not operate properly. The larger the difference between the high and low thresholds, the more immune the meter is to input signal noise.

A2 Low High B2 Threshold Threshold

a -12mV +12mV b -150mV +150mV

11.3 MODES OF OPERATION

Input

Arm Signal

Gate

Internal Clk The measurement starts with an input signal transition in one direction and ends, after the

expiration of the selected gate time, with the next input signal transition in the same direction such that the conversion time or period is measured over an integral number of input cycles. The internal Start signal ARMS the gate circuit so that the next input signal transition actually OPENS the gate. When the gate is detected to be open, the gate time begins. At the end of the gate time, the gate circuit is DISARMED, and the next input signal transition CLOSES the gate. When both inputs A & B are active with separate gates, such as measuring Rate on both channels, the gate time begins when both gates are detected to be open. The program calculations begin when both gates are detected to be closed.

11.4 RATE

A ONLY, RATE A B Either one or two channels of rate may be displayed. If one channel

is displayed the input is on channel A and decimal point1, scale1 and offset1 apply to the input. If two channels are displayed decimal point1, scale1 and offset1 apply to channel A and decimal point2, scale2 and offset2 apply channel B. Either channel may be displayed by pressing and releasing the reset key . Gate time setting selects the update rate of meter. The longer the gate time, the more cycles of the input signal averaged. If the period of the input signal is longer than the gate time, only 1 period of the input is calculated and determines the conversion time. Time out is the length of time the meter waits for a signal to start a conversion or end a conversion. If pulses are not received before the time out ends, the meter reads zero. The longer the time out, the lower the minimum frequency the meter can display Frequency displayed in Hz with scale factor of 1 and multiplier of 1. Increasing the multiplier increases resolution (.1 to .00001Hz). Decreasing the multiplier allows display in kHz or MHz. Rate displayed in engineering units by scale factor and multiplier. Using coordinates of 2 points to scale meter, low input and high input are entered in Hz.

BATCH displays total of channel A as item 1, grand total or number of batches as item 2 and rate as item 3. Batch requires a Batch Relay board that plugs into the Analog Output Slot. It contains Relay #3 for use as the Batch Controller. This leaves Relay #1

and Relay #2 for use as either Pre-warn, End-of-process or Rate alarms. When Reset in the BATCH mode, the counter resets and then displays "rEAdy". It waits until the

Reset button is pushed and then immediately energizes Relay #3 and starts displaying the Batch Total. When the preset value is reached, Relay #3 de-energizes for a period of time equal to the GATETIME setting. At the end of GATETIME, the Batch Total resets,

-24-

Relay #3 energizes and the cycle repeats. As an option, the cycle can be reset from an external signal FUNCTION RESET. The GATETIME is not used and Relay #1 remains de-energized until the FUNCTION RESET external input is grounded for a minimum of 3.33 mS. Sometime during that period, the Batch Total is reset and Relay #1 is energized. The Batch Total is displayed as Item #1 and may be configured to count up from 0 to the preset value, or to count down from the preset value to 0. The preset value is placed in OFFST1 and the Batch Total is the total input pulses with SCALE1 and DECPT1 applied. In the BATCH mode, SCALE1 is always set to a positive value whether counting up or counting down. The Grand Total is kept as Item #2. SCALE1 and DECPT1 also apply to the Grand Total except the absolute value is used so that the Grand Total always increases from an initial value of zero when the counter is initially Reset. It is calculated as the sum of the previous Batch Totals + the current Batch Total. The Grand Total can overflow to the exponential format. As an alternative, Item #2 can be configured to be the Number of Batches instead of the Grand Total. If it is, SCALE1 does not apply to it and the Decimal Point is always 1. Item #3 is the Rate calculated with a fixed 20 mS (or 1 cycle min) gatetime. SCALE2, OFFSET2 and DECPT2 apply to the Rate. Relay #1 is activated by SETPT#1 and Relay #2 is activated by SETPT#2, and each may be configured for either Item#1 - Batch Total (Pre-warn), Item #2 - Grand Total or # Batches, or Item #3 - Rate. It is possible to configure both for the same Item. An example would be two Pre-warns.

RATE A , TOTAL A displays total of channel A as item 2, and rate as item 1. Total is a sample time total determined the rate multiplied by the time between conversions. This input is used if square root or custom curve is selected. Decimal point2, scale2 and offset2 apply to total and is calculated from the displayed valued of rate and decimal point1, scale1 and offset1 apply to rate. Total may count down from an offset value by entering a negative scale factor. Use Rate A, Total B to display the rate and total of a single linear input by tying channel A and B inputs together.

RATE A AND TOTAL B displays total of channel B as item 2, and rate of channel A as item 1. Decimal point2, scale2 and offset2 apply to total and decimal point1, scale1 and offset1 apply to rate. Total may count down from an offset value by entering a negative scale factor. Rate and total of a single input may be displayed by tying channel A and B inputs together

RATE A+B is the same as Rate A, Rate B except that Rate A is displayed as item 2, Rate B is displayed as item 3 and the sum of A and B is displayed as item 1. Decimal point 1 applies to both A and B and decimal point 2 applies to the sum of A and B. The resolution of the sum is determined by setting the multiplier (Resolution) from .00001 to

100000. RATE A-B is the same as Rate A+B except that B is subtracted from A

-25-

RATE AxB is the same as Rate A+B except that A is multiplied by B. RATE A/B (Ratio) is the same as Rate A+B except that A is divided by B. Rate A and

B may be scaled such that the ratio of A/B is 1. When the value of B increases the ratio is a number less than 1 and when it decreases the number is greater than 1.

RATE A/B-1 (Draw) is the same as Rate A/B (Ratio) except that 1 is subtracted from the ratio to give a zero value when the ratio of the 2 inputs is 1. This is used in applications where two rollers, etc. should be rotating at the same speed and displays the amount of tension between the two rollers.

11.5 PERIOD

A ONLY, PERIOD A B Period of either channel A input or both A and B may be displayed.

If one channel is displayed the input is on channel A and decimal point1, scale1 and offset1 apply to the input. If two channels are displayed decimal point1, scale1 and offset1 apply to channel A and decimal point2, scale2 and offset2 apply channel B. Either channel may be displayed by pressing and releasing the reset key . The displayed period of the input signal is not affected by the gate time but the longer the gate time the more periods of the input signal that are averaged. The shorter the gate time, the faster the meter outputs and alarms are updated.

PERIOD A+B is the same as Period A, Period B except that Period A is displayed as item 2, Period B is displayed as item 3 and the sum of A and B is displayed as item 1. Decimal point 1 applies to both A and B and decimal point 2 applies to the sum of A and B. The resolution of the sum is determined by setting the multiplier (Resolution) from .00001 to

100000.

PERIOD A-B is the same as Period A+B except that B is subtracted from A PERIOD Ax/B is the same as Period A+B except that A is multiplied by B. PERIOD A/B (Ratio) is the same as Period A+B except that A is divided by B. Period

A and B may be scaled such that the ratio of A/B is 1. When the value of B increases the ratio is a number less than 1 and when it decreases the number is greater than 1.

11.6 TOTAL

A ONLY, TOTAL A B Total of the number of pulses of either channel A or both A and

B may be displayed. If one channel is displayed the input is on channel A and decimal point1, scale1 and offset1 apply to the input. If two channels are displayed decimal point1, scale1 and offset1 apply to channel A and decimal point2, scale2 and offset2 apply channel B. Either channel may be displayed by pressing and releasing the reset key or both channels may be reset using the external input "Function Reset". By setting an offset in the meter and a negative scale factor, the meter counts down from a preset value to zero.

-26-

TOTAL A-B UPDN is the same as Total A, Total B except that Total A is displayed as item 2, Total B is displayed as item 3 and the difference of A minus B is displayed as item 1. Decimal point 1 applies to both A and B and decimal point 2 applies to the sum of A and B. The resolution of the sum is determined by setting the multiplier (Resolution) from .00001 to 100000.

BURST measures the frequency of a burst of pulses from channel A as item 2, and total number of bursts as item 1. Decimal point2, scale2 and offset2 apply to total and decimal point1, scale1 and offset1 apply to rate. Gate time must be set greater than the minimum frequency of the burst frequency and less than the minimum time between bursts. Time out is set to the maximum value.

TOTAL A AND RATE B displays total of channel A as item 1, and rate of channel B as item 1. Decimal point2, scale2 and offset2 apply to total and decimal point1, scale1 and offset1 apply to rate. Total may count down from an offset value by entering a negative scale factor. Rate and total of a single input may be displayed by tying channel A and B inputs together.

TOTAL A AND B UP/DOWN CONTROL displays total of channel A as item 1. Decimal point1, scale1 and offset1 apply to total. Up/down counting is controlled by the input level of channel B. The maximum input frequency on A that can be counted is 250 kHz, or a minimum of 4 uS between pulses. If the menu item SLOPE is set to 0 for Channel B (Digit 6) then a low level on the B input causes Channel A to count Up and a high level on the B input causes Channel A to count Down. If the SLOPE of Channel B is set to 1, the opposite occurs.

TOTAL A AND B INHIBIT displays total of channel A as item 1. Decimal point1, scale1 and offset1 apply to total. The input signal to be counted is applied to Channel A and the Inhibit control signal to Channel B. The maximum input frequency that can be counted is 2 MHz or a minimum of 0.5 uS between pulses. If the menu item SLOPE is set to 0 for channel B (Digit 6) then a low level on the B input allows counting of the Channel A input signal and a high level on the B input inhibits counting. If the SLOPE of Channel B is set to 1, the opposite occurs.

TOTAL A+B is the same as Total A, Total B except that Total A is displayed as item 2, Total B is displayed as item 3 and the sum of A and B is displayed as item 1. Decimal point 1 applies to both A and B and decimal point 2 applies to the sum of A and B. The resolution of the sum is determined by setting the multiplier (Resolution) from .00001 to

100000.

TOTAL A-B is the same as Total A+B except that B is subtracted from A TOTAL AxB is the same as Total A+B except that A is multiplied by B. TOTAL A/B (Ratio) is the same as Total A+B except that A is divided by B. Total A and

B may be scaled such that the ratio of A/B is 1. When the value of B increases the ratio

-27-

is a number less than 1 and when it decreases the number is greater than 1.

11.7 TIME INTERVAL

TIME INTERVAL A TO B measures time between an input on channel A and an input

on channel B. Time measurement starts when a pulse is applied to channel A (positive edge if slope A is 0, negative edge if slope A is 1) and the measurement ends when a pulse is received on channel B (positive edge if slope B is 0, negative edge if slope B is 1). A single pulse may be measured by tying input A and B together and selecting a positive or negative edge to start (Slope A) and the opposite polarity edge to stop (Slope B). If a number of start and stop pulses occur during the gate time, the value displayed is the average of the pulse widths. The value is updated at the end of each gate.

11.8 STOPWATCH

STOPWATCH A TO A measures time between an start pulse on channel A and a

second pulse on A to stop timing. Timing may be set to start and stop on either the positive or negative edges of the pulses (Slope A). The time (item #1) may be displayed in seconds, minutes or hours (with decimal point) using scale and multiplier with the clock time display (hr, min, or sec)selected. Clock time (fixed format) displays HH:MM:SS. Time is reset to 0 when a new start pulse occurs. Item #2 displays the accumulated total time of Item #1.

STOPWATCH A TO B measures time between an start pulse on channel A and a stop pulse on B. to stop timing. Timing is the same as A to A except in addition to separate start and stop pulses, by tying input A and B together, a single contact closure may start and stop timing by selecting the opposite Slope for A and B.

11.9 PHASE ANGLE

PHASE ANGLE A TO B measures the phase relationship between a signal on input A

and input B. The displayed value is 0 to 360 degrees. Resolution is determined by Scale

12.2 RATE

Rate A is the voltage or current input converted to a frequency output of 0 to 100kHz.

The period of the frequency is measured and converted to a rate by 1/period and applying Scale1 and Offset1. Scaling may also be set by using coordinates of 2 points where low and high input signals and the corresponding low and high displayed values are entered.

12.3 BATCH

Batch displays total of voltage or current input as item 1, grand total or number of

batches as item 2 and rate as item 3. Relay #1 is used as the Batch Controller. This leaves Relay #2 for use as either Pre-warn, End-of-process or Rate alarm. When reset in the batch mode, the counter resets and then displays "rEAdy". It waits until the reset button is pushed and then immediately energizes Relay #1 and starts displaying the batch total. When the preset value is reached, Relay #1 de-energizes for a period of time equal to the Time out setting. At the end of time out, the Batch Total resets, Relay #1 energizes and the cycle repeats. As an option, the cycle can be reset from an external signal Function Reset. The Time Out is not used and Relay #1 remains de-energized until the Function Reset external input is grounded for a minimum of 3.33 mS. Sometime during that period, the Batch Total is reset and Relay #1 is energized. The Batch Total is displayed as Item #1 and may be configured to count up from 0 to

-29-

the preset value, or to count down from the preset value to 0. The preset value is placed in Setpoint 1 and the Batch Total is the total with Scale1 and decimal point1 applied. In the Batch mode, Scale1 is set to a positive value to count up and a negative value to count down. Offset1 is set to zero when counting up and to the preset value when counting down. The Grand Total is kept as Item #2. Scale1 and decimal point1also apply to the Grand Total except the absolute value is used so that the Grand Total always increases from an initial value of zero when the counter is initially Reset. It is calculated as the sum of the previous Batch Totals + the current Batch Total. The Grand Total can overflow to the exponential format. As an alternative, Item #2 can be configured to be the Number of Batches instead of the Grand Total. If it is, Scale2 does not apply to it and the Decimal Point is always 1. Item #3 is the Rate calculated with a selectable gatetime. Scale2, Offset2 and decimal point 2 apply to the Rate. Relay #2 is activated by Setpoint#2, and may be configured for either Item#1 - Batch Total (Pre-warn), Item #2 - Grand Total or # Batches, or Item #3 - Rate.

12.4 RATE AND TOTAL

Rate A, Total A rate is calculated the same as Rate A above and displayed as Item1

and total is calculated based on the rate versus time between conversions. Scale2 and Offset2 are calculated from the displayed rate and apply to total. The rate may be displayed as units per second, per min, or per hour but the total is always incremented by the displayed value of the rate every second when the scale factor is set to 1. If the rate is per minute, the rate must be multiplied by 1/60 , so that the total will equal the displayed rate at the end of 1 min. To totalize units per hour , the rate must be multiplied by 1/3600. The scale and multiplier for Scale 2 is set to 1.66667 and .01 for units per minute and 2.77778 and .0001 for units per hour. Total is displayed as Item 2.

Total A, Rate A same as above except total is displayed as Item1 and rate as Item2

12.5 1/RATE

1/Rate A is the voltage or current input converted to a frequency output of 0 to 100kHz.

The period of the frequency is measured and converted to time by applying Scale1 and Offset1. Scaling may also be set by using coordinates of 2 points where low and high input signals and the corresponding low and high displayed values are entered. An example is converting speed to time and displaying the time an item takes to travel through an oven.

13.2 QUADRATURE DECODING

The quadrature decoder board generates up(+) and down(-) counts that are arithmetically totalized on the main counter board and then displayed. The decoder board has input circuitry that may be jumpered for either single-ended input signals or balanced line driver signals. It will accept the normal A & B quadrature signals and, if present, a zero index signal. The A & B signals are 90 deg out of phase and the phase relationship of A & B determine whether up counts or down counts are produced. Up counts add to the total and down counts subtract from the total.

Since incremental optical encoders may have a different A & B phase relationship to indicate up and down, the board has a jumper E7 (BPOL) on the B signal to allow selection of the desired phase. Without the jumper, Up output pulses are created when the B signal has a positive transition while the A signal is at a positive level (A leads B). With the jumper installed, Up output pulses are created when the B signal has a negative transition while the A signal is at a positive level (B leads A).

A With the phase shown E7 open - Counts up B E7 jumpered - Counts down

With the opposite phase shown, the effect of E7 reverses. The board has jumpers that allow counting by 1, 2 or 4 counts per cycle of the A or B signals.

The edges that are counted are: X1 = positive transitions of the A signal. X2 = positive and negative transitions of the A signal. X4 = positive and negative transitions of both the A and the B signals.

Digital filtering is provided for the A & B signals to reduce the probability of noise providing false counts.

Some optical encoders create a zero index signal once per revolution that indicates when the encoding wheel is at its zero position. Each time this signal is created, the total count should be a multiple of the number of counts per revolution of the coding wheel. If this feature is enabled in the counter, the counter checks to see if the total counts is an exact multiple of the counts per revolution. If so, it does nothing, and if not, it changes the total to the closest exact multiple. The counts per revolution are entered into the counter via the menu item Pulses. From 0 to 59,999 pulses may be entered. If X2 or X4 counting is enabled on the board, then the value entered into Pulses should be the counts (or pulses) per revolution of the encoder multiplied by this factor of X2 or X4. Also, if Scale is a factor other than 1, include it as a multiplying factor when determining the value of Pulses to enter.. Do NOT include the value of Offset1.

For example:

If the encoder produces 256 cycles per revolution and X2 counting is selected by a jumper on the board, and from the front panel Menu of the counter, SCALE1 is set to 3 and OFFSET1 is set to 100, then from the front panel menu set PULSES = 256 * 2 * 3 = 1536.

-32-

The zero index channel contains the same digital filtering that is provided for the A & B channels. It contains a Polarity jumper that allows selection of either a positive or negative zero index signal. It also contains two Control inputs, C1 and C2 that control the ANDing of the zero index signal with the Channel A and Channel B signals. See “Zero Index Setup” below.

The Item indicator light (center right) may be used to determine the location of the Zero Index. This indicator is lighted while the zero index signal is being received. The zero index signal must be jumpered for the correct polarity. If, during encoder motion, the indicator is on more than it is off, it is likely that the zero index signal is jumpered for the wrong polarity.. If so, add a Polarity jumper to switch E8, position C. If it already has a jumper, remove it.

From the menu, a value may be entered for Offset1. As explained below under “Mechanical Zero”, Offset1 allows a mechanical zero position different from the zero index position. The displayed value is the sum of the following:

1. The total bidirectional counts from the optical encoder since the last counter reset or function reset.

2. The correction factor from the last zero index correction calculation.

3. Offset 1

For example:

Suppose that the encoder contains 30 pulses per revolution and X1 counting is used. Further suppose that when the mechanics are at 0 position, the zero index is at 10 and the OFFSET 1 = 10 and the counter is reset when the encoder is at the 5 position.

Reset

Position 0 5 10 20 30 40 50 Index ^ ^

Internal Total 0 5 15 25 35 45 Correction 0 -5 -5 -5 -5 -5 OFFSET 10 10 10 10 10 10

Display 10 10 20 30 40 50

Internal Total -5 0 5 15 25 35 45 Correction -5 -5 -5 -5 -5 -5 -5 OFFSET 10 10 10 10 10 10 10

Display 0 5 10 20 30 40 50

Once the index point has been passed, the display matches the position. Prior to that, the

display is in error. When the counter is displaying Quadrature Total and the Total is reset using the Reset & Peak buttons (Function Reset), the internal Total is set to zero, but the zero index correction is not affected. This results in a display of the correction value plus Offset 1. To zero the internal Total and the correction value, the counter must be reset using the Reset & Menu buttons (Meter Reset). This results in a display of OFFSET 1.

-33-

13.3 ZERO INDEX SETUP

The relationship between the zero index correction signal and the Channels A & B signals varies with different encoder model numbers and different manufacturers. To accommodate this variation, the Quadrature board has control jumpers and selectable outputs that provide ANDing of the zero index signal with all possible combinations of the Channel A & B signals.

Consider a typical encoder model that produces the waveforms shown below. Assume X4 counting is selected. The count increases and decreases on each A & B transition and remains steady between transitions. The counts shown below the waveforms represent the effect of the zero index correction ZI if no ANDing is used. Note the difference in count in the regions between transitions when counting up and then counting down. The zero index correction is made on the leading edge transition of the zero index signal. When counting down, the leading edge is the trailing edge of the signal shown below because time is increasing from right to left.

A Channel B Channel Zero Index

Up -3 -2 -1 0 1 2 3 4 5 ZI Down -6 -5 -4 -3 -2 -1 0 3 4 ZI | | | | | | | | Up Region -3 -2 -1 0 1 2 3 4 5 Down Region -5 -4 -3 -2 -1 0 3 4 5

It follows that a wide zero index signal causes a discrepancy in the count in the regions between transitions when counting up and counting down. To correct this situation, AND the zero index signal with the A & B channel signals. Assume for this example the zero index is ANDed with the inverse of A (/A) and the inverse of B (/B) to produce ZIY as shown below.

A Channel B Channel ZIY Zero index AND ZIY = ZIR

Up -3 -2 -1 0 1 2 3 4 ZIR Down -4 -3 -2 -1 0 1 2 3 ZIR | | | | | | | | Up Region -3 -2 -1 0 1 2 3 4 Down Region -3 -2 -1 0 1 2 3 4

By ANDing the zero index signal with the A & B channels, there is no regional discrepancy

-34-

between counting up and counting down. There are 2 control signals, C1 and C2, and 3 outputs, ZI, ZIX and ZIY that may be jumpered

to provide 8 selections of ANDed signals or the zero index signal without ANDing.

Zero Index Polarity Jumper Position

E7 Positive a Negative None

Zero Index ANDing Jumper Position

E10 E8 Zero Index (no ANDing) c Zero Index AND /A a Zero Index AND /B a a Zero Index AND A a b Zero Index AND B a a, b Zero Index AND /A AND /B b Zero Index AND /A AND B b a Zero Index AND A AND /B b b Zero Index AND A AND B b a, b

The manufacture's data sheet for the optical encoder will show the position and width of the zero index signal with respect to the A channel and B channel signals. Selection of one of the above combinations depends on that relationship and the polarity of the channel A & B signals when the mechanical position is zero. Be sure to take into account the selected phase relationship determined by the presence of or absence of jumper E7-a (BPOL). Jumper E7-a is selected to cause the display to count in the proper direction. If jumper E7 is in place, the channel B signal will have the opposite polarity from the channel B output of the encoder.

13.4 MECHANICAL ZERO

By using the Counter’s OFFSET1 value, it is possible to place the mechanical zero (zero counter reading) at some point other than the location of the zero index. The following technique describes how to accomplish this.

1. Set the E8 & E10 jumpers as described above to produce the desired Zero Index signal.

2. Set OFFSET1 = 0.

3. Reset the counter (counter reset).

4. Rotate the optical encoder in the positive direction until the reading jumps to zero at the zero index point (Item indicator lights).

5. Reverse the direction of rotation until the desired zero mechanical position is reached.

6. Note the reading and enter that reading into OFFSET1 using the opposite polarity of the display.

7. Reset the counter and it will display the OFFSET1 value because the internal total

-35-

counter=0 and the correction=0. The position of the encoder when the counter is reset is not critical.

8. Rotate the optical encoder past the zero index point to set the internal correction.

9. Return to the desired zero mechanical position and verify a zero reading.

This completes the procedure. If the encoder is rotated back to mechanical zero, it should read zero.

Note: Any time the counter is powered up or reset, the optical encoder should be rotated past

the zero index point one time to set the internal correction

If no zero index signal is available from the optical encoder, perform the following procedure.

1. Remove any E10 jumpers to eliminate the Zero Index signal.

2. Set OFFSET1 = 0.

3. Adjust the optical encoder to the mechanical zero position and with it in this position, reset the counter.

13.5 SETUP SUMMARY

Summarizing the complete setup procedure:

1. Set the input signal jumpers. A. For single-ended signals such as TTL or CMOS, use jumpers c of E2, E4 and E6 and

jumper a of E6. Input signals are applied as follows:

Channel A, P5-1X (AH) Channel B, P5-3Y (BH) Channel Z, P5-5Z (ZH) Zero Index Ground, P5-6Z

If an excitation voltage is required, use jumper a of E2 and jumper a of E4

B. For differential line driver or balanced input signals, use jumper b for E2, E4 and E6. If

120 ohm line termination resistors are desired, place jumpers E1, E3 and E5.

2. Set the correct counting direction by placing or omitting the Channel B polarity jumper

E7.

3. Choose X1, X2 or X4 counting and omit a and b of E9 for X1, place a of E9 for X2 or

place b of E9 for X4. Determine the scale factor to be used by the counter and set SCALE1 to this value using the counter Menu. Most often it will be set to 1.00000 with a multiplier of 1.

4. If the Zero Index is to be used, do the following:

A. Temporarily place jumper c of E10 and rotate the encoder while watching the Item

indicator of the display. If it is OFF most of the time, the Z polarity is correct. If it is ON most of the time, the Z polarity is incorrect, so add jumper c of E8 if it is missing, or remove jumper c of E8 if it is in place.

B. From the manufacturer's specifications for the encoder showing the relationship of the

Zero Index signal to the Channel A and Channel B signals, determine from the table above the desired positions of jumpers a and b of E8 and a, b or c of E10. If not

-36-

used here, remove jumper c of E10 that was placed for the test in A. above. C. From the manufacture's specifications for the encoder, determine the number of cycles

per revolution. Multiply this by 1, 2, or 4 depending on the selection of X1, X2 or X4 counting and multiply that result by the counter scale factor. Put the final result in the counter Menu item, PULSES.

5. Finally, follow the procedure outlined above under the heading titled, MECHANICAL ZERO.

13.7 QUADRATURE RATE

Rate and direction may also be displayed using an extended version of the counter. Using quadrature to determine rate not only has the advantage of displaying direction but also eliminates errors due to vibration and jitter that cause erroneous readings in standard rate meters. The meter uses A-B to display quadrature rate. Scale 1 is used to set A to the proper value and scale 2 is set to identical values. Rate (I1) is the difference between Channel A and Channel B.

20. 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 main board , the V-to-Fsignal conditioner and on the analog output board. The crystal on the main board is calibrated via the menu item "calib". Using an accurate, known frequency, the meter is calibrated by entering the error of the in parts per million. If the frequency reading is high, the value entered is negative and if the reading is low, the value is positive.

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. Software for calibration of the V-to-F and analog output boards is available from the factory.

22. GLOSSARY OF TERMS

Calibration A menu item that compensates for any error in the crystal oscillator in the

meter. With an accurate, known frequency input, a value in parts per million is entered equivalent the error in parts per million of the input signal. If the displayed reading is lower than the actual signal input, a positive value is entered. If the displayed reading is higher, a negative value is entered.

Calculated Total In most cases, total is calculated by directly counting the number of pulses

of the input signal and applying a scale factor to read in engineering units. Some totals (Total A, Rate A) are calculated totals. In these cases, the meter determines the rate of the input signal and multiplies by the time between rate conversions to calculate total. The scale factor for total is based on the displayed value of rate. A scale of 1 always produces a total at the end of 1 second equal to the displayed rate. For a display of 300 where the rate is equivalent to gallons per second, a scale factor of 1 produces a total that at the end of 1 second is 300, 2 seconds 600, etc. However, if the displayed rate is 300 gallons per minute, then the scale factor must be 1.66667 with a multiplier of .01 ( a multiplier of 1/60 since the rate value is in minutes) to produce a total a the end of 1 minute of 300, at 2 minutes 600 etc.

Coordinates of 2 Points Instead of using scale and offset to display in engineering units, the

coordinates of 2 points may be used. The low input is entered as frequency in Hertz for the lowest frequency input to the meter and low reading is entered as the value to be displayed at that frequency. High input is entered as frequency in Hertz for the highest frequency input to the meter and high reading as the value to be displayed at that frequency.

Custom Curve In the extended version of the counter, the unit is capable of linearizing the

input signal by using the software provided and loading the values into

-51-

EEPROM via the serial communications. Up to 240 data points may be entered into a test file with one set of values equivalent to input signal and the second set of values the desired display at that input.

Deviation Either alarm may operate in the deviation mode. In the menu item

"deviation", a value is entered equivalent to the amount above and below the setpoint at which the alarm operates. For example, if the value entered is 100, and the setpoint value is 1000, the alarm would energize above 1100 and below 900.

Frequency The meter is calibrated such that a scale factor of 1 and offset of 0 causes

the input to the meter to display directly in Hertz with a resolution of 1 Hz. To increase or decrease the resolution, the scale factor multiplier may be increased or decreased.

Gate Time The Gate Time determines the update time of the display. The longer the

time, the slower the outputs and display are updated, but in most modes, the longer the Gate Time, the more cycles of the input signal that are averaged to produce the reading. In the total mode, the gate is always open, but the gate time setting still determines the update rate of the meter. The actual conversion rate of the meter is the Gate Time + 1 period of the input signal. At very low frequencies, the update rate of the meter becomes slow due to the period of the input exceeding the Gate Time.

Hysteresis Either alarm may operate in the hysteresis mode. In the menu item

"deviation", a value is entered equivalent to the amount above and below the setpoint at which the alarm operates. For example, if the value entered is 10, and the setpoint value is 1000, if the alarm is set to energize above the setpoint, the alarm would energize above 1010 would not deenergize until the displayed value goes below 990. This mode reduces relay chatter and excessive cycling of the load.

Item Item refers to the display Item number. For example, in Total A+B, the

sum of A + B is Item #1, Total A is Item #2 and Total B is Item #3. When the meter is reset, Item #1 is always displayed, to view another Item, depress and release the reset button. When Item 1 is displayed, the yellow view (V) LED is out item 2 the LED is lit, and item 3 the LED flashes.

Offset An offset value from -999,999 to 999,99 may be entered in the offset menu

item. The offset may be used in the totalize mode as a preset value and the total is counted down from the preset to zero.

Period Period is the time of one complete cycle of the input frequency. A scale

factor of 1 and multiplier of 1 produce a display in microseconds.

Quadrature A quadrature encoder generates 2 signals 90 degrees out of phase. The

phase relationship depends on the direction of rotation of the encoder. The meter counts up or down depending on the phase. Quadrature is used to determine length or position.

-52-

Phase Angle In this mode, the meter determines the phase angle between the signals

on Channel A and Channel B. The phase angle is measured from 0 to 360 degrees

Pulses The menu item pulses is used to set the number of pulses generated by

a quadrature encoder for each zero index pulse. The setting is equal to the number of pulses per revolution of the encoder (times 2 or 4 if the count by 2 or 4 is selected on the signal conditioner) times the scale factor.

Rate This is the same as frequency except that a scale factor is applied to the

input signal to display in engineering units such as RPM, gallons per hour, etc.

Resolution This is a menu item that controls the resolution of the arithmetic functions

(A+B, A-B, AxB, A/B, A/B-1). The displayed value may be multiplied by

0.00001 to 100,000 in decade steps.

Scale Scale is the menu item that allows an input to be scaled in engineering

units. The scale factor consists of two parts; the scale factor is a multiplier that may be set from 0.00001 to 9.99999 and a multiplier from 0.00001 to 100,000 in decade steps. When scale is selected, the most significant digit flashes allowing the value of that digit to change, pushing the digit select key moves the flashing digit to the right. When the right hand digit is flashing, pushing the digit select key again causes the multiplier to be displayed. Pushing the value select key changes the value of the multiplier. The next time the digit select key is depressed, the display goes back to the scale factor.

Time Interval Time interval is the measure of time between the occurrence of a pulse on

Channel A and Channel B. The time may be measured from the leading or trailing edge of the pulse on A to the leading or trailing edge of the pulse on B.

Time Out When making conversions, the gate time is started on an edge of the input

signal and ended on the same edge. If no input is received, the meter will never update. The time out setting allows a wait time from .01 seconds to 199.99 seconds for the meter to receive a signal. At the end of time out, the meter updates and displays 0. The longer the time out, the lower the displayed value of the input frequency. A shorter time out allows the meter to update at a higher rate.

V-to-F Converter The voltage to frequency converter takes voltage or current inputs (0 to

1mA, 4 to 20mA, 0 to 10V) and converts them to a frequency. This allows the meter to totalize an analog input as well as displaying rate. In addition, for differential pressure transducers, the meter can calculate the square root of the rate input and display total. Nonlinear analog inputs may be linearized using the custom curve function.
