Introduction

The Daniel Digital Rate Internal Display is an explosion-proof pulse input rate/display fully
featured for demanding applications in hazardous areas or in the harshest environmental
conditions. It can be programmed using the four through-glass buttons, without
removing the cover, or with four internal push-buttons.

The numeric rate display reads up to five digits and the alphanumeric total/tag display
reads up to 7 digits. The total overflow feature reads up to 12 digits. The alphanumeric
display can also be programmed to display any combination of numbers and letters up to
seven characters long for use as engineering units and/or the process identification tag.

The backlight increases the visibility of the display under various lighting conditions. The
enclosure contains threaded conduit holes and integrated pipe or wall mounting slotted
flanges.

Alarm acknowledge Front panel ACK button resets output and screen indication.

Pulse output K-Fac­tor (Count)

K-factor (COUNT) programmable from 0.000001 to 9999999. Rate pulses
are generated as a scaled output of the rate input with one output pulse per
K-factor (count) number of input pulses. Total and grand total pulses are
generated for every total or grand total increment selected. (e.g. K-factor
value of 100 generates one pulse every time the total is incremented by 100
units). Rate retransmission pulses one to one for input pulses, up to maxi­mum output speed. K-factor is not used for retransmitting outputs.

The through-glass buttons are designed to filter normal levels of ambient interference and
to protect against false triggering. However it is recommended that the through-glass
buttons be turned off (slide THRU-GLASS BUTTONS switch to OFF) if there is an infrared
interference source in line-of-sight to the display or if the buttons are not needed.

1. Install the display facing away from sunlight, windows, reflective objects and any
sources of infrared interference.

2. Keep the glass window clean.

3. Tighten the cover securely.

4. Use a password to prevent tampering.

User manual 31

Setup and programming

If the cover has not been installed and secured tightly, allow up to one minute for
the through-glass buttons to self calibrate when the cover is tightened.

Important

The Thru-glass buttons are designed to constantly recalibrate for ambient conditions. When
the cover position is changed, the cover is removed, or an object that was placed over the
front window is removed, it may take a moment for the Thru-glass buttons to recalibrate to
the change in conditions.

Allow up to 2 minutes for the Thru-glass buttons to recalibrate to new conditions in these
cases where the cover position was changed, or the front window is being unblocked.

6.3 Open collector outputs (OUTPUT)

The meter is equipped with two NPN open collector outputs that may be set up for pulse
outputs, alarms, timed pulses, or turned off.

Pulse outputs are based on K-factor, total or grand total counts, or one-for-one retransmit
for input pulses. Both outputs may be used to generate a quadrature output based on any
pulse menu output type. An output test mode may be selected to generate pulses at a
constant programmable frequency.

Alarms are available based on the rate, total, or grand total. The alarm status appears on
the display even if the output is not wired. The outputs may also be forced on or off. A
timed pulse output generates constant pulses at a specified frequency and on time. The
output may be disabled by selecting Off.

Open collector outputsFigure 6-2:

Product advanced features

6.3.1 Output 1 and 2 Setup (OUT 1, OUT 2)

The function of open collector output 1 and 2 is configured using the Off, Pulse, Alarm,
and the Timer menus detailed below.

User manual 59

Product advanced features

Pulse output (PULSE)

The pulse output may be assigned to rate, total, grand total, retransmit, quadrature, or
test.

Pulse output (PULSE)Figure 6-3:

Rate pulse output (rAtE)

The rate based pulse output is a factor of the rate display and count (output K-Factor). The
rate display is a factor of the input pulses, time base, and the input K-factor. The rate of
output pulses over one time base (seconds, minutes, hours, days) is defined below in
terms of input pulses and the input K-factor and count parameters.

60 LTM Internal Display

Product advanced features

Rate pulse output (rAtE) equationFigure 6-4:

For example, if the input K-Factor value is set to 10, and the count is set to 10, one output
pulse is generated for every 100 input pulses.

Total and grand total pulse output (totAL, Grtot)

A total and grand total based pulse output is a factor of the associated total and count
(output K-Factor). A pulse is generated for every total accumulation amount equal to the
count.

If the maximum output frequency is exceeded, the meter displays the message PUlse
OVERRNG alternating on the display.

Retransmit output (rEtr)

The retransmitting pulse output sends an output pulse for every input pulse; duplicating
the input signal. The output generates a pulse at the falling edge of the input pulses.

No additional programming is required for retransmitting the pulse output. If the
maximum output frequency is exceeded, the meter displays the message PULSE OVERRNG
alternating on the display.

Quadrature output (quAd)

The pulse output set to quadrature duplicates the other open collector output, but lags by
¼ duty cycle (90 degrees out of phase). For example, Out 1 will follow Out 2, if Out 1 is set
to quad. Only one output should be set to quad. If both outputs are set to quad , both
outputs will be disabled. The other output should be programmed as required for the
quadrature output function, and it must be a pulse (PULSE) output selection.

Test output (tESt)

The test output setting programs the output to generate pulses at a programmed
constant frequency. Set the frequency decimal point location in the dEc.Pt menu, and then
enter the required output frequency in Hz in the PULSE menu.

Alarm output (ALrm)

Alarm outputs may be assigned to rate, total, or grand total; or be forced on or off.

User manual 61

Product advanced features

Alarm output(ALrm)Figure 6-5:

Rate alarm (rAtE)

Program the rate set point to trigger the alarm. Rate alarm deadband is determined by the
difference between set and reset points. Minimum deadband is one display count. If set
and reset points are programmed the same, output will reset one count below set point.

Total or grand total alarm (totAL, Grtot)

Program total or grand total set point. A pulse alarm generates when the set value is
reached by the total or grand total.

62 LTM Internal Display

Product advanced features

If the total/grand total is set for manual reset, this alarm will remain until the total/grand
total is reset to 0.

If automatic total/grand total reset is enabled, the output generates an alarm for a period
of time programmed in ADVANCED → T RESET → Auto → T DELAy. After this time delay, the
total/grand total resets to 0 and the alarm clears.

If Out 1 and Out 2 are set for total or grand total alarm, the auto reset will be triggered on
the highest of the two alarm set points.

For details on setting the total or grand total automatic reset time delay, see Section 6.9.

Force on state (On)

This alarm mode forces the output to be active or on. This mode is primarily used to test
alarm systems.

Force off state (OFF)

This alarm mode forces the output to be inactive or off. This mode is primarily used to test
alarm systems.

6.4

Timer output (tmEr)

The timer output produces a constant width pulse at a constant rate. Program the Delay
period for one period from 0.1 to 999999.9 seconds (time from the start of one pulse to

the start of the next pulse).

Program the On time for the active low pulse from .01 to 99999.99 seconds (pulse width).
The on time must be less than the delay time.

Select Start to begin outputting the constant timed pulse. Select Stop to end outputting
the constant timed pulse.

Scaling the 4-20 mA analog output (Aout)

Use the Analog output menu the 4-20 mA output based on display values.

The 4-20 mA analog output (if equipped) can be scaled to provide a 4-20 mA signal for any
display range selected for either the rate, total, or grand total. The output may be disabled
(dSAbL) and will only output the minimum signal.

No equipment is needed to scale the analog output. Program two display values and
corresponding mA output signals.

User manual 63

Product advanced features

Scaling the 4-20 mA analog output (Aout)Figure 6-6:

NOTICE

Note that when power is removed from the meter, the analog output will drop below 1 mA.
Take this effect into consideration when designing any system using the 4-20 mA output.

6.5

64 LTM Internal Display

Gate function (GATE)

Use the gate function for displaying slow pulse rates. When using the programmable gate,
the meter displays pulse rates as slow as 1 pulse every 9,999 seconds (0.0001 Hz). The
gate function can also be used to obtain a steady display reading with a fluctuating input
signal.

There are two settings for the GATE, low gate (LO) and high gate (HI).

Low gate (LO GATE)

For most applications the low gate setting should be left at 1 second. Increase the low gate
setting to obtain a steadier rate display. The rate display updates in accordance with the
low gate setting. For example, if the low gate is set at 10, the display will update every 10
seconds. Changes in rate between updates will not be reflected until the next display
update.

High Gate (HI GATE)

Set the high gate value to correspond with the highest expected pulse period (lowest pulse
rate). For instance, if the meter must display a rate when there is 1 pulse coming into the
meter every 10 seconds, set the high gate to 11 seconds. When the signal is removed from
the meter, the display will show the last reading for 11 seconds; then it will read zero.

6.6 Contact debounce filter (FILTER)

Use the filter function (FILTER) for applications where the meter is set up to count pulses
generated by switch contacts. There are three settings, HI (high speed), mEd (medium
speed), and LO (low speed). High speed disables the contact debounce filter and allows
any pulse of the minimum specified width for the input wired. Press ENTER when med or
LO is displayed to enable the filter function.

Product advanced features

6.7

6.8

The medium filter ignores signals faster than 250 Hz max, or pulse widths less than 2 ms at
50% duty cycle. The low filter ignores signals higher than 100 Hz, or pulse widths less than
5 ms at 50% duty cycle.

Low-flow cutoff (CUTOFF)

The low-flow cutoff feature allows the meter to be programmed so that the often
unsteady output from a transmitter at low flow rates, always displays zero on the meter.

The cutoff value may be programmed from 0 to 9999.9. Below the cutoff value, the meter
will display zero. Programming the cutoff value to zero disables the cutoff feature.

Scaling and calibration (SCALCAL)

Important

It is very important to read the following information before proceeding to program the meter:

• There is no need to recalibrate the meter for frequency in Hz when first received from the

factory.

• The meter is factory calibrated for Hz prior to shipment. The calibration equipment is certified

to NIST standards.

User manual 65

Product advanced features

Important

Performing a scaling or calibration operation will override any K-Factor programming. Similarly,
completing the K-Factor menu will override any scaling or calibration performed on the meter. Verify
the method of programming required. Use the password protection feature to secure the meter if
necessary.

Three methods of programming the display show the engineering units based on input
pulses:

• Use the Factor menu to enter a K-Factor.

• Use the Scale menu to enter the scaling without a signal source.

• Use the Calibrate menu to apply a signal from a calibrator or a flowmeter.

The K-Factor, scale and calibrate functions are independent of each other. The meter uses
the last function programmed. The Scale and Calibrate functions can use up to 32 points
(default is 2). The number of points should be set in Scale and Calibrate accordingly under
the Number of Points (noPtS) menu selection prior to scaling and calibration of the meter.
See Number of points (noPtS) for details.

Scale and calibrate the meter using this menu. Refer to Section 5.7.2 for information on
using a K-Factor for programming the input.

6.8.1 Undo K-Factor, scale, and calibration (Undo?)

A confirmation menu appears whenever the input programming changes from K-Factor to
scaling or calibration; or from scaling or calibration to K-Factor.

See figure below for an example of a meter programmed with a k-factor that is being
reprogrammed to utilize input scaling.

Undoing K-Factor, scale and calibration (Undo?)Figure 6-7:

6.8.2 Scale the meter (SCALE)

The pulse input can be scaled to display the process variable in engineering units. A signal
source is not needed to scale the meter. Program the inputs and corresponding display
values.

66 LTM Internal Display

Product advanced features

A programmed scaled input works with Automatic unit conversions. The units for the
display values being entered are a combination of the programmed Rate unit and the time
unit (timE UNIT) entered in the Scale menu.

For example, if the Rate unit is gallons, and the time unit (timE UNIT) is seconds, the units
for the display values entered in the Scale menu are gallons/second.

For instructions on how to program numeric values see Section 5.3.

Multi-Point linearization (noPtS)

Up to 32 linearization points can be selected under the noPtS function. The multipoint
linearization can be used to linearize the display for non-linear inputs.

Number of points (noPtS)

Enter number of linearization points. The default value is 2 points. For linear inputs
requiring only 2 scale points, leave the number of points at 2.

User manual 67

Product advanced features

Scale units (SCALE UNITS)

Enter the units associated with the desired scale values. Selecting the scale display units
allows the meter to perform automatic unit conversions.

Pulse input time unit (timE UNIT)

This is the time component for the engineering units of the entered display values. Enter
the appropriate units/second, units/minute, units/hour, or units/day that corresponds to
the entered values in the display 1-32 (dSP) menus.

For example, if the display values are entered in gallons/second, set the time unit to
seconds.

Important

Programming Note Save (SAVE?)

After entering the last display value, the scaling entries must be saved (SAVE?) before they will be put
into effect. However, you may move past this selection using the Up arrow key if you need to go back
and correct an earlier entry. Once confident in the entries, however, the user must navigate back to
the Save menu screen (SAVE?) and press the Enter key to save the changes.

6.8.3 Calibrate the meter (CAL)

Refer to Section 5.7.2 or Section 6.8.2 to scale the meter without a signal source .

Calibrate the pulse input to display the process in engineering units. Apply the appropriate
input signal and follow the calibration procedure. The use of a calibrated signal source is
strongly recommended.

A calibrated input will work with Automatic unit conversions. The units for the display values
that are a combination of the programmed Rate Unit and the time unit (timE UNIT)
entered in the Calibrate menu.

For example, if the Rate unit is gallons and the time unit (timE UNIT) is seconds, the units
for the display values entered in the Calibrate menu are gallons/second.

Error messages (Error)

An error message indicates that the calibration or scaling process was not successful. After
the error message is displayed, the meter reverts to input 2 during calibration or scaling,
allowing the appropriate input signal to be applied or programmed.

Conditions causing an error message:

1. Input signal is not connected to the proper terminals or it is connected backwards.

2. Minimum input span requirements are not maintained.

3. Input 1 signal inadvertently applied to calibrate input 2.

Minimum input span

The minimum allowed input span is 1 Hz. This is the minimum difference between input 1
and input 2 signals required to complete the calibration or scaling of the meter.

Important

After entering the last display value, save (SAVE?) the calibration entries. You may move past this
selection using the Up arrow key if you need to go back and correct an earlier entry. Then save the

6.10.4 Non-resettable grand total

The grand total may be configured to be a non-resettable grand total. This is a permanent
setting. Configuring the grand total as a non-resettable grand total locks out all setup
parameters that could be used to reset the grand total or change the setup of the grand
total; including input selection, rate scaling, and conversion factors.

To configure the meter for non-resettable grand total mode, enter the non-resettable
grand total password below into the Pass GT parameter in the Password menu.

The non-resettable grand total permanently locks the following setup menus and
parameters from being changed: input selection, K-Factor, K-Factor units, grand total
units, grand total conversion factor, grand total decimal point, scaling, calibration, grand
total alarms, pulse input filter, and cutoff.

CAUTION!

METER LOCKING HAZARD

Locking the meter into a non-resettable grand total is not reversible. It is a permanent meter
configuration. Doing so will permanently prevent most input parameters from being altered.
This should be the last step after verifying all setup parameters.

The real time clock is used to trigger data log events, and is recorded at every logged data
point. The menu displays the date and time.

Date display exampleFigure 6-18:

The above display example shows the date to be June 27, at 14 hours, 32 minutes, and 36

User manual 79

Product advanced features

Setting real time clock (SETTIME)Figure 6-19:

The year, month, day, hour, and minute may all be set by the user. The real time clock will
need to be reset if external power and battery power are lost.

Changing the time (hours and minutes) will reset the seconds clock to 0.

Log time setup (LOGTIME)

The Log Time menu contains four log points (LOG 1 to LOG 4). Each log time is configured
separately. For each daily log time desired, enable a log, and set the log time for the hours
and minutes the log is to be recorded. The time is set in real-time, based on the real time
clock setup.

The Log Time feature will roll-over, deleting the oldest data logs (in blocks of 8) when the
log is full and new logs must be recorded. This makes it the most useful for long-term data
logging.

Interval setup (INTERVL)

The Interval menu sets the time interval for data logging. Every time interval, one data
point will be recorded. To enable interval data logging, enable the feature, and set the
interval time for the hours and minutes between each log.

The Log Interval feature will not delete old data, and data logging will stop when the log is
full. This makes it the most useful for short periods and logging specific functions.

6.12.5 Backup and restore (BACkUP)

Important

The meter saves all parameter settings and no reprogramming is necessary when power is lost and
restored to the meter. The total and grand totals are saved during a power loss. Only the maximum
and minimum displays are reset when power is lost.

The features are used to save and restore programmed settings. Programming can be
restored to a known saved good configuration, or to factory defaults. This is useful to
restore meters whose programming has been altered in unknown ways, or to quickly
restore known good settings if mistakes are made during reprogramming.

Backup and restore (BACkUP)Figure 6-22:

The save feature (SAVE?) saves all current parameter settings into the memory of the
backup restore. The backup restore feature is loaded with factory default settings until a
new configuration is saved.

The load feature (LoAd?) restores all parameters to the programmed values stored in
backup restore memory. The load feature will not affect the current password settings, or
allow the editing of permanently locked parameters due to the enabling of the non­resettable grand total feature. See Section 6.10.4.

CAUTION!

Once meter parameters have been saved to memory by the backup restore feature there is no
recovering the previously saved settings.

Once parameters have been loaded into the meter from the backup restore feature there is no
recovering the previously programmed settings.

The default feature (dEFLt) restores all parameters to the factory default values. Factory
default reset does not change the saved backup restore settings, override passwords, or
edit parameters locked by a permanent non-resettable grand total. See Section 6.10.4.

6.12.6 Battery power symbol alert (BAT SyM)

The Battery Power Symbol Alert menu is used to enable or disable the battery alert symbol
on the display. This is a useful way to be aware of a power failure to a model with battery
backup.

When enabled, the battery symbol will appear whenever the meter is powered as a battery
backup. This is detected when the meter being powered from DC or loop-power
experiences power loss, subsequently switching over to battery power.

The indicator will not appear if the meter is powered on via battery power, only when there
is applied power to the DC or loop-power lines, followed by power loss. This prevents the
batter indicator from appearing at all times for a primarily battery powered application.

The battery symbol will flash in a low battery condition regardless of the setting of this
parameter.
