INTRODUCTION

The ProtEX-RTP PD6830 is a rugged, explosion-proof, pulse
input rate/totalizer for demanding applications in hazardous
areas or in harsh environments. It can be programmed using
the four SafeTouch through-glass buttons, without removing
the cover, or with four internal push-buttons. The top
numeric display will read rate or total up to five digits and the
alphanumeric bottom display will read up to 7 digits,
13 digits with the total overflow feature. The alphanumeric
display can also be programmed to show any combination of
numbers and letters up to seven characters long for rate,
total, grand total, engineering units and/or identification tag.
The backlight makes the display more visible in any lighting
condition. The enclosure is provided with threaded conduit
holes and integrated pipe or wall mounting flanges.

ORDERING INFORMATION

* When DC-powered, battery will provide backup power when DC power is lost.
** Backlight is constant when DC powered and momentary when battery powered.

PULSE OUTPUT
K-FACTOR
(COUNT)

K-factor (couNT) programmable from

generated as a scaled output of the
rate input with one output pulse per K­factor (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 will generate 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.

Battery Replacement

Battery-equipped models have a battery charge monitor.
When the battery is nearing the end of its capacity the screen
will periodically flash the message LO BATTERY and the BAT
indicator on the screen will flash. The recommended
replacement interval for models using the battery as a primary
power source is determined by the power and feature use, as
shown on page 5. The battery should be replaced when the
low battery indication is on the screen.

The total is backed up in non-volatile memory when the low
battery monitor is tripped. It is recommended that an updated
reading be manually backed up prior to changing out the
battery.

NOTICE: Battery may only be replaced with an original
Model PDABAT36C supplied by Precision Digital. Do not
recharge battery. Do not replace with used battery.

 Remove cover and display module and disconnect

display module ribbon cable.

 Carefully cut and remove the cable ties supplied for

shipping (if present).

 Remove the spent battery and prepare it for disposal.
 Install new PDABAT36C into battery clip with polarity as

shown in Figure 14.

 Reconnect and fasten display module. Install enclosure

cover.

 Resume operation.

SETUP AND PROGRAMMING

Overview

Setup and programming is done through the infrared
through-glass SafeTouch buttons, or using the mechanical
buttons when uncovered. There are two slide switches
located on the display module. One is used to configure the
input and the other is to lock or unlock the SafeTouch
Buttons.

SafeTouch Buttons

The PD6830 is equipped with four sensors that operate as
through-glass buttons so that it can be programmed and
operated without removing the cover (and exposing the
electronics) in a hazardous area. These buttons can be
disabled for security by using the THRU-GLASS BUTTONS
switch and selecting the OFF setting. This switch is located
on the back of the removable electronics module.

SafeTouch Button Operation

To actuate a button, press and remove one finger to the
glass directly over the marked button area. Remove finger to
at least 4 inches away from the glass in between button
activations. SafeTouch and mechanical buttons may be held
to cycle through menus or digits in place of repeatedly
pushing a button.

Figure 14. Battery Orientation

13

PD6830 Explosion-Proof Pulse Input Rate/Totalizer Instruction Manual

SafeTouch Button Equalize Delay

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

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

SafeTouch Button Tips and Troubleshooting

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

SafeTouch Button Tips:

 To the extent possible, install the display facing away

from sunlight, windows, reflective objects and any
sources of infrared interference.

 Keep the glass window clean.
 Tighten the cover securely.
 Use a password to prevent tampering.
 If the cover has not been installed and secured

tightly, it may take a moment for the SafeTouch
buttons to properly self calibrate when the cover is
tightened.

After all connections have been completed and verified,
connect the ribbon cable to the display module, fasten the
display module to the base, install enclosure cover, and then
apply power.

Important Programming Note:

The units selected in this menu are the desired display
units only. The units defined by the k-factor of a flow meter
are entered in the K-Factor menu as part of the Factor Unit
menu programming. See K-Factor Units (FuNiT) on page
19 for details.
This allows the display units to be different than the units
defined by the flow meter, or be changed easily after initial
programming. Unit conversions for rates and totals are
performed automatically by the meter. See Automatic Unit
Conversions on page 22 for details.

IMPORTANT

Performing a k-factor operation will
override any scaling or calibration
programming. Refer to Scaling &

Calibration (SCALCAL) on page 29 for more
information on these programming methods.

Entering the K-Factor (Factr)

The meter may be scaled using the K-factor, or conversion
factor, function. Most flowmeter manufacturers provide this
information with the device. Enter the K-Factor (Factr)
menu and select the units defined with the k-factor (example:
pulses/gal), the decimal point with highest resolution
possible, and program the K-Factor value. The meter will
automatically calculate the flow rate using the K-Factor and
the units and time base selected.

Display Units (Units)

The Units menu is used to select the display rate units and
time (example: Gal/s) and the display units for total and
grand total.

K-Factor Units (FuNiT)

Select the units defined with the k-factor (example:
pulses/gal). This is usually provided by the flowmeter
manufacturer. This does not set the rate display units, and
only relates to entering the K-factor. To set or change the
rate display units, see Setting the Rate Display Units (rateU)
on page 20.

The K-factor unit may be a custom unit (CUST).
Automatic unit conversions are not performed when the K-

factor unit is set to custom. See page 22 for information on
the automatic unit conversion feature.

K-Factor Decimal Point (dec.pt)

Set the number of decimal places necessary to enter the K­factor value. The decimal point may be set with up to six
decimal places or with no decimal point at all.

Pressing the Right arrow moves the decimal point one place
to the right (including no decimal point). Pressing the Up
arrow moves the decimal point one place to the left.

K-Factor Value (factr)

Enter the K-factor value. This value is entered in Pulses/Unit
as defined by the K-Factor Units parameter. Most flowmeter
manufacturers provide this information with the device.

The following units may be selected as the base units for
rate, total, and grand total. Time base for rate and a
multiplier for total and grand total units may also be selected
separately.

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 Timer menus detailed
below.

Pulse Output (PUlse)

Pulse outputs may be assigned to rate, total, grand total,
retransmit, quadrature, or test.

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 is also
selectable to generate pulses at a constant programmable
frequency.

Alarms are available based on the rate, total, or grand total.
The alarm status will show 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.

A total reset output generates a pulse whenever the selected
total is reset, total or grand total, regardless of the reset
method used. The On time is programmable between 0.10
and 99,999.99 sec.

The output may be disabled by selecting Off.

Rate Pulse Output (rate)

A 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.

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

26

PD6830 Explosion-Proof Pulse Input Rate/Totalizer Instruction Manual

Total & 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 will be
generated for every total accumulation amount equal to the
count.

If the maximum output frequency would be exceeded, the
meter will display the message pUlse OVERRNG alternating
on the display.

Retransmit Output (retr)
The retransmitting pulse output will send an output pulse for

every input pulse, essentially duplicating the input signal.
The output will generate a pulse at the falling edge of every
input pulse.

No additional programming is required for a retransmitting
pulse output.

If the maximum output frequency would be exceeded, the
meter will display the message pUlse OVERRNG alternating
on the display.

Quadrature Output (quad)
The pulse output set to quadrature will duplicate the other
open collector output, but lag by ¼ duty cycle (90 degrees
out of phase). For example, Out 1 will follow Out 2, if Out 1 is
set to
outputs are set to
other output should be programmed as desired for the
quadrature output function, and must be a 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 DECPT menu, and
then enter the desired output frequency in Hz in the PULSE
menu.

. Only one output should be set to

Alarm Output (alrm)

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

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 will

generate when the set value is reached by the total or grand
total.

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 will
generate an alarm for a period of time programmed in
ADVANCE  T RESET  Auto T DELAY. After this time
delay, the total/grand total will reset to 0 and the alarm will
clear.

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 Total Reset (T Reset) on page 31.

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.

27

PD6830 Explosion-Proof Pulse Input Rate/Totalizer Instruction Manual

CAUTION

Please 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.

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.

Total Reset Output (t rst)

A total reset output generates a pulse whenever the selected
total is reset, total or grand total, regardless of the reset
method used. Program the On Time from 0.10 to 99,999.99
seconds. This is the amount of time the open collector output
will remain on after the total or grand total has been reset.

Scaling the 4-20 mA Analog Output (Aout)

The Analog Output menu is used to program 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; simply
program two display values and corresponding mA output
signals.

Gate Function (GATE)

The gate function is used for displaying slow pulse rates.
Using the programmable gate, the meter is able to display
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, low gate setting should be left at 1
second. Increase low gate setting to obtain a steadier rate
display. The rate display will update in accordance with the
low gate setting, for example if low gate is set at 10, the
display will update every 10 seconds; changes in rate
between updates will not be reflected until next display
update.

High Gate (HI GaTE)

Set the high gate value to correspond to 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.

Contact Debounce Filter (FILTER)

The filter function (FILTER) can be used for applications
where the meter is set up to count pulses generated by
switch contacts. There are three settings, HI (high speed),
nmed (medium speed), and LO (low speed). High speed
disables the contact debounce filter and allows any pulse of
the minimum specified width for the selected input type.
Press ENTER when nmeD or LO is displayed to enable the
filter function.
The medium filter ignored 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.

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.

Scaling & Calibration (SCALCAL)

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 traceable to
NIST standards.

There are three methods of programming the display to
show the correct 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 exclusive 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 page 29 for details.

This menu is used to scale and calibrate the meter. For
information on using a k-factor for programming the input,
refer to Entering the K-Factor (Factr) on page 19.

Undoing K-Factor, Scale, and Calibration
(Undo?)

Whenever the input programming is being changed from
using k-factor to scaling or calibration; or from scaling or
calibration to k-factor, a confirmation menu appears. This
prevents accidental changing of the input programming.

The example below shows a meter programmed with a k­factor being reprogrammed to utilize input scaling.

Scaling 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; simply
program the inputs and corresponding display values.

A programmed scaled input will work with Automatic Unit
Conversions as described on page 22. The units for the
display values that must be 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 page

15.

Multi-Point Linearization (nopts)

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

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

Number of Points (nopts)

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.

PD6830 Explosion-Proof Pulse Input Rate/Totalizer Instruction Manual

Important Programming Note: Save (save?)

After entering the last display value, the scaling entries
must be saved (SAUE?) 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 (SAUE?) and
press the Enter key to save the changes.

Important Programming Note: Save (save?)
After entering the last display value, the calibration entries
must be saved (SAUE?) 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 and earlier
entry. Once confident in the entries however, the user must
navigate back to the Save menu screen (SAUE?) and press
the Enter key to save the changes.

Pulse Input Time Unit (Time UNIT)

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

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

Scale Input and Display (INPUT,
DSPLY)

Each scale input point is defined by an input frequency and a
corresponding display value.

The frequency inputs may be entered with up to three
decimal places. To access the decimal location digits when
entering a frequency, use the Right button to scroll to the
three decimal location digits.

Manual Multi-point Entry (INP, DSP)

Manual entry of the linearization data is done once the
number of points has been selected (NO PTS). Input signal
levels (InP 1-32) for up to 32 points, along with the
desired/corresponding meter reading (dSP 1-32), should be
entered for each linearization point.
Each scale point (1-32) has an input value and a display
value. The input value is the number of pulses/sec
(frequency), and the display value is the corresponding
display value for that input in the time unit selected
(example: gallons per minute, or GAL/M)

For instructions on how to program numeric values see
Setting Numeric Values, page 15.

1. Press the Up arrow button to scroll to the Calibration
menu (CAL) and press Enter.

2. The meter displays nopts. For a linear signal, press
Up arrow. For a non-linear signal, refer to Multi-Point
Linearization (nopts), page 31.

3. The meter displays CAL UNITS. Press Enter to select
the input units/pulse. The menu will read FuNiT.

4. Use the Up arrow to select the time unit. If entering
display values in units/second, press Enter.
Otherwise, select the time unit. Refer to Pulse Input
Time Unit (Time UNIT) on page 31.

5. The meter displays inp 1. Apply a known signal and
press Enter. The display will flash while accepting
the signal.

6. After the signal is accepted, the meter displays dsp
1 Press Enter. Enter a corresponding display value
for the signal input, and press Enter to accept.

7. The meter displays inp 2. Apply a known signal and
press Enter. The display will flash while accepting
the signal.

8. After the signal is accepted, the meter displays dsp

2. Press Enter. Enter a corresponding display value
for the signal input and press Enter to accept.

9. After completing calibration the save? display will
need to be
acknowledged using the Enter key before calibration
will take effect.

Calibrating the Meter (CaL)

To scale the meter without a signal source refer to Entering
the K-Factor (Factr) on page 19 or Scaling the Meter
(Scale) on page 29.

The pulse input can be calibrated to display the process in
engineering units by applying the appropriate input signal
and following the calibration procedure.

The use of a calibrated signal source is strongly
recommended.

A calibrated input will work with Automatic Unit Conversions
as described on page 22. The units for the display values
that must be entered 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.

The multi-point linearization feature (nopts) can be used to
linearize the display for non-linear signals. For instructions
on how to utilize this feature, see Multi-Point Linearization
(nopts), page 31.

PD6830 Explosion-Proof Pulse Input Rate/Totalizer Instruction Manual

Error Message (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.

The error message might be caused by any of the following
conditions:

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

2. Minimum input span requirements not maintained.

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

Minimum Input Span

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

Multi-Point Linearization (nopts)

Up to 32 linearization points can be selected under the
nopts function. The multi-point linearization can be used to
linearize the display for non-linear inputs. Linearization data
can be entered using a known accurate signal source (InP
1-32) and then entering the desired/corresponding meter
reading (dSP 1-32) for that input signal level. These points
are established via direct entry (SCALE) or with an external
calibration signal (CAL).

Calibration Units (CAL UNITS)

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

Pulse Input Time Unit (Time UNIT)

This is the time component to be used when calibrating a
number of input pulses per time unit to equal a certain
display value.

For example, if the inputs being entered in pulses/second
the time unit would be set to seconds.

Total Reset (T Reset)

This menu is used to select the ways the total and grand
total may be reset.

programmed amount of time (T DELAY) and then resets the
total to zero.

For timed reset, select T RESET  t rst  Time T
RESET and enter the time of day at which the total should be
reset. The total value will be reset every day at the specified
time.

Press the Enter button, at any time, to accept a setting;
otherwise press the Menu button to exit without saving
changes.

Total Alarm Time

The T DELAY parameter is used by the NPN open collector
outputs when they are programmed as total alarms. If total

reset (t rst) is programmed to Auto the time delay (T
DELAY) is the length of the associated Out 1 or Out 2 total

alarm prior to the total being reset to 0.
For information on programming the NPN open collector

pulse outputs as total alarms, see Alarm Output
programming on page 27.

PD6830 Explosion-Proof Pulse Input Rate/Totalizer Instruction Manual

System (SYSTEM)

The system function is used to set the real time clock, set
daily data log times, enable/disable the backlight, access
analog output controls used in troubleshooting, store,
restore, and backup restore feature, enable/disable the
battery power alert symbol on the display, and review basic
system identification information.

Set Real Time Clock (SETTIME)

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.

Figure 15. Date Display Example

The above display example shows the date to be June 27, at
14 hours, 32 minutes, and 36 seconds. The display date will
toggle with the year.

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.

Data Log Setup (DATALOG)

The Data Log menu is used to setup and enable the data log
functions. The meter may contain up to 1024 records, each
containing date, time, rate, total, grand total, and log
number.

There are two ways to configure the time when a data log is
recorded. The Log Time feature allows up to 4 data logs to
be recorded each day, at specific times. The Log Interval
feature allows a data log to be recorded each time a time
interval has passed.

Only the Log Time or Log Interval may be active at once.
While one type of data logging has been enabled, the other
menu will be inaccessible.

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 real­time, 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.

If set to F.STOP, 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.

If set to Cont, the Log Interval feature will delete the old data
when full and continue logging data. The Log Interval 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.

PD6830 Explosion-Proof Pulse Input Rate/Totalizer Instruction Manual

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 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.

View Data Log (LOGVIEW)

The Log View menu allows on-screen browsing of the data
log points stored in the meter. Data points may be navigated
by viewing the log number, date and time, total, or grand
total amounts. A known log may be jumped to immediately,
avoiding a lengthy search for data. All logs may be deleted
with the ERASE command, requiring confirmation.

Once the log records are displayed, use the Up and Right
arrows to change the log entry being viewed. The Enter key
changes the displayed information for the same log.

Backlight (BAKLITE)

The Backlight menu is used to enable or disable the
backlight. This feature is particularly important for the
battery-powered models with momentary backlight. This
feature is not available for models with a loop output
powered backlight.

Analog Output Calibration (AO CAL)

This feature is only used at the factory for diagnostic
purposes. It is not recommended to access this menu
without instruction from technical support.

Backup & Restore (BACKUP)

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.

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 non-resettable grand total feature. See
Non-Resettable Grand Total described on page 33.

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 Non-Resettable Grand Total, as described on
page 33.

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.

pressing the Enter key while WAKEUP? is flashing. The meter
will return to the normal run mode.

OPERATION

Front Panel Buttons Operation

Standby Mode (STANDBY)

Standby mode is available on battery powered and battery
backup models only.

The Standby menu is used to enter a power-saving standby
mode that will turn off the display and activate a low power
mode for the through-glass buttons. Signal processing
operations will continue to run. This mode may be used to
reduce power consumption and increase battery life when
the meter is not in use.

It may take up to 3 seconds for the meter to enter standby
mode after confirming the flashing display with the Enter
button.

The following SafeTouch button information is reprinted from
SafeTouch Button Operation on page 13.

PD6830 Explosion-Proof Pulse Input Rate/Totalizer Instruction Manual

SafeTouch Power Save Mode

SafeTouch buttons enter a power saving mode after three
minutes of inactivity. This mode is indicated by a pause

symbol ( ) appearing in the lower right of the display.
Only the MENU button is monitored in this mode. To
activate the SafeTouch buttons, press and hold the menu
button for up to five seconds. The display will read AWAKE,
and the SafeTouch buttons will be fully enabled.

SafeTouch Disabled Mode
When the cover is removed, the four mechanical buttons

located next to the sensors may be used. The sensors are
disabled when a mechanical button is pressed and will
automatically be re-enabled after 60 seconds of inactivity.

The SafeTouch power symbol ( ) will blink in the lower
right of the display if the buttons are disabled due to a
mechanical pushbutton being pressed.

IMPORTANT

SafeTouch buttons will not work if two or
more buttons are detected as being
pressed simultaneously. As a result, be
careful to avoid triggering multiple buttons
or reaching across one button location to
press another.

SafeTouch Button Equalize Delay

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

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

unblocked.

SafeTouch Button Operation

To actuate a button, press and remove one finger to the
glass directly over the marked button area. Remove finger to
at least 4 inches away from the glass in between button
activations. SafeTouch and mechanical buttons may be held
to cycle through menus or digits in place of repeatedly
pushing a button.

SafeTouch Button Tips and Troubleshooting

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

SafeTouch Button Tips:

 To the extent possible, install the display facing away

from sunlight, windows, reflective objects and any
sources of infrared interference.

 Keep the glass window clean.
 Tighten the cover securely.
 Use a password to prevent tampering.
 If the cover has not been installed and secured

tightly, it may take a moment for the SafeTouch
buttons to properly self calibrate when the cover is
tightened.

After all connections have been completed and verified,
connect the ribbon cable to the display module, fasten the
display module to the base, install enclosure cover, and then
apply power.

Grand Total Reading (GrTOTAL)

The grand total is a separate total that is not reset when the
total is reset. This allows the complete total to be tracked by
the grand total, while individual batch, or daily totals are
reset regularly.

To display the grand total, press the Up/Display button. The
display will read GRTOTAL, and the GT symbol will appear
indicating the grand total is being displayed on the bottom
display. After 10 seconds, the bottom display will return to
showing total. To lock the grand total on the display, press
Enter. Pressing Menu at any time will return to normal run
mode.

Note: If the Display menu has been setup to display the
grand total on the bottom display, pressing the Up/Display
button will display the maximum and minimum readings
followed by the total.

Toggle Lower Display Parameter

The maximum and minimum (peak & valley) readings
reached by the rate are stored in the meter since the last
reset or power-up. The meter shows MAXIMUM or MINIMUM to
differentiate between run mode and max/min display. The
previous total and grand total value reached prior to being
reset are also stored.

To display the maximum and minimum readings or the
previous total and grand total use Up/Display button to cycle
the bottom display. Maximum and minimum are displayed
after the grand total.

Press the Enter button to remain in Max/Min/Previous
display mode. If Enter is not pressed, the Max/Min/Previous
display readings will time out after ten seconds. The meter
will return to display the actual reading. Pressing Menu at
any time will return to normal run mode.

Resetting the Total (RESET TOTAL?)

If manual Total Reset is enabled in the Program menu, the
total may be reset by pressing the Reset button and using
the Enter button to confirm the reset.

Additionally if programmed for manual reset, the total may
be reset using a normally open pushbutton connected
across the terminals RST and COM.

Note: The total is cleared immediately when Enter button is
pressed. Totalization will then continue, even if the Enter
button or external reset button continues to be held
down/triggered.

Resetting the Grand Total (RESET GrTOT?)

If manual Grand Total Reset is enabled in the Program
menu, the grand total may be reset using the Reset button.

To reset the grand total, display the grand total by pressing
the Up/Display button. While grand total is being displayed,
press the Reset button. Confirm the reset with the Enter
button.

Resetting Max/Min Readings (RESET
MAXIMUM, MINIMUM)

The maximum and minimum readings may be reset by
pressing the Reset button while displaying either the
maximum or minimum. The display will show RESET to verify
the reset of maximum or minimum value.

The maximum and minimum must be reset individually.

Reset Meter to Factory Defaults

Reset to factory defaults will restore most meter parameters
to their factory default setting.

When the parameters have been changed in a way that is

difficult to determine what’s happening, it might be better to

start the setup process from the factory defaults.
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 Non­Resettable Grand Total, as described on page 33.

Instructions to load factory defaults can be found in the
Backup & Restore (BACKUP) menu on page 36.

Factory Defaults & User Settings

The following table shows the factory setting for most of the
programmable parameters on the meter. Next to the factory
setting, the user may record the new setting for the particular
application.
