DPG-6700 Instruction Sheet

The“Direct Drive Difference” in Digital

Form DPG-6700

The 3D Digital Pressure Gauge DPG-6700 is a loop pow­ered electronic instrument designed for applications
needing high accuracy, excellent long-term stability,
trouble-free operation, high performance and long
life. No separate power supply is needed, the
DPG-6700 takes power directly from the cur­rent loop. It incorporates a large 0.75" four
digit, 25 bar LCD display with a four key
sealed membrane switch.

The integral pressure transducer is a high
quality, all stainless steel media-isolated sen­sor with no internal “O” rings, no silicone oil
and no welds. The gauge is intended for use in
the measurement of gases and liquids compati­ble with stainless steel.

The accuracy of the gauge is +/- 0.25% of full scale
over a temperature of 0°C to 55°C (32°F to 131°F).
Full operating temperature range is -40°C to 85°C
(-40°F to 185°F).

The gauge is ideally suited to process applications
with features such as an adjustable software filter to
stabilize readings where the pressure is fluctuating. The pressure units are selectable
and are displayed on the LCD. When a new unit is selected, the gauge automatically
converts the reading to match the units. A configurable bargraph gives the user a quick
visual indication as to where the pressure is relative to low and high values and whether it
is increasing or decreasing. A high and low pressure reading detection shows the opera­tor the pressure extremes that the process was exposed to. In addition, the input pres­sure is continuously compared against two adjustable setpoints that can be adjusted using
the front keypad on the gauge. The 4-20 mA loop can be configured anywhere within the
range of the gauge, as well as reverse acting. The gauge uses the loop current as its pri­mary power. With the absence of loop current it automatically switches to the internal “C”
size 3.6 volt replaceable lithium cell. It continues to operate as a battery-powered gauge
until loop power returns. The gauge is designed with the latest microcontroller technology
for extremely long battery life. To extend battery life even longer, a programmable power­on-timer can be set from 0 to 720 minutes.

The enclosure is the standard 3D 4-1/2" ‘Dyna-Mount’ ABS case with a special swivel fit­ting and moveable flange. The gauge can be converted to front or back flange and bot­tom or back mount in the field with no more than a screwdriver . The digital pressure
gauge accepts all of the optional accessories offered in the mechanical gauge line includ­ing the metallic GP-140 chemical seal, elastomeric isolator GP-400 and the 316 SS sin­tered filter RS-380-1 for particulate laden process medias.

And finally, the DPG-6700 is manufactured and serviced by the company that makes THE
Premier Pressure Gauge on the market today. Get The Direct Drive Difference in

INTRODUCTION

The DPG-6700 digital pressure gauge is
shipped with the internal battery installed
so that it is ready to use. Press any key
and the gauge will power-up. A complete
LCD segment test is performed followed by
the full scale reading of the gauge in psi
units. The gauge may be adjusted to local
atmospheric condition using the
ZERO/TARE function - see page 4. The
full scale reading of the gauge in psi units
can be displayed at any time by simultane-

ously pressing both arrow keys (▲ and ▼).

The DPG-6700 measures “gauge” pres­sure. “Gauge” pressure measures the
input pressure referenced to ambient
atmospheric pressure. The gauge will also
read vacuum down to absolute zero. The
vacuum readings will be displayed as
minus in the chosen unit of measure.

Mount the gauge to a suitable flat surface
using the flange and hardware supplied.
Avoid mounting the gauge with the LCD
display facing direct sunlight. The display
temperature range is -40°F to +185°F.
(-40°C to +85°C)

NOTE: Although flange mounting is sug­gested for high vibration applications, the
flange does not have to be used to mount
the gauge. Mounting the gauge using its
process connection to a pipe is acceptable
as long as excessive vibration is not expe­rienced.

Attach the gauge to the pressure fitting
using teflon tape or equivalent. Tighten
the process connection by hand and con­tinue to tighten 2 to 3 turns using a 9/16"
wrench on the stem of the gauge. Do not
use the gauge case to tighten pressure fit­ting.

LOOP WIRING

The DPG-6700 is designed to transmit
analog 4 to 20 mA signals over an industry
standard 2-wire current loop for the control
of valves, actuators, and other devices
commonly used in process control. The
gauge also is powered directly from the
two wires of the current loop. Connect the
loop wires to terminals 1(+) and 2(-); power
requirement is 12 to 32 VDC. See wiring
diagram page 15. The loop is protected
against open and short circuits and
reverse wiring. The maximum load resist­ance that can be tolerated in the loop is
determined by the supply voltage, but
should not exceed 1000 ohms. Refer to
page 15 for the maximum load resistor
verses the supply voltage.

- A 250 ohm loop resistor can be used
over the supply voltage range from 14 to
32 Vdc.

- At 12 VDC supply voltage, the maxi­mum loop resistor for 20 mA loop output
current is 150 ohms.

- If using a 500 ohm loop resistor and a
desired full scale loop output of 20 mA,
the supply voltage must be between 17
and 32 VDC.

HAZARDOUS AREA OPERA

TION

The DPG-6700 gauge is CSA-certified for
CLASS I, DIVISION 2, GROUPS C and D
areas when mounted in a suitable enclo­sure. The device may be operated as
CLASS I, DIVISION I, GROUPS C and D
intrinsically safe, if the following conditions
are met:

A. The gauge is powered from a CSA-certi-

fied zener barrier rated 30 volts max.,
120 ohms min. A suitable barrier is a
Stahl part no. 9002/13-280-110-00; fol­low the installation instructions supplied
with the barrier.

B. The switch outputs, if used, are connect-

ed to the sensor inputs of an Altronic DA
or DD annunciator system with the 690
series power supply. Contact 3D
Instruments for additional information.

In addition, the following requirements
must be met (see NFPA standard no. 493):

1. The intrinsically-safe gauge wires within
the panel enclosure must be kept at
least two (2) inches away from other
wiring.

2. Wiring to valves, actuators and other
control devices must have a grade of
insulation capable of withstanding an AC
voltage of 500 volts RMS.

3. Control wires must be run in separate
conduits and junction boxes from high
voltage wires such as ignition, fuel
valve, and other high voltage wiring.
Refer to page 14 for wiring instructions.

W

ARNING:

SUBSTITUTION OF COMPONENTS MAY
IMPAIR INTRINSIC SAFETY AND/OR
SUITABILITY FOR CLASS I, DIV. 2.

DO NOT DISCONNECT EQUIPMENT IN
DIV. 2 ENVIRONMENT UNLESS POWER
IS SWITCHED OFF OR THE AREA IS
KNOWN TO BE NON-HAZARDOUS.

OUTPUT SWITCH

WIRING

There are two user-programmable output
switches that can be set anywhere within
the range of the gauge. A fault condition
will cause one or both of the output switch­es to turn ON/OFF to their common.
These switches are solid state, open drain
FET’s and are isolated from the loop sup­ply. The common is also isolated from the
loop supply thus allowing for low-side or
high-side switching. The switches are
rated at 100 VDC, 1 Amp continuous.
Please refer to the wiring diagram on page

16.

ZERO /

TARE

The zero function is used to “zero” the
gauge to compensate for any ambient
effects that cause an offset at zero pres­sure. The zero offset is limited to +/-2 psi
to +/-10 psi depending on the range of the
gauge. To “zero” the gauge, vent the pres­sure to the gauge to atmosphere (0 psig);
press the SETUP key, the gauge will read
“ZErO”, press ENTER and the gauge will
be zeroed at the current pressure value.

The tare function can be used to offset the
zero point of the gauge to any vacuum or
positive gauge pressure from 0 to 20% of
full range of the gauge. Both the under
and over arrows will blink to indicate when
tare is used. To access the tare function,
press the SETUP key until the display
reads “tare”, press ENTER and the gauge
will be zeroed at the current pressure
value. The tare offset can be canceled at
any time by pressing SETUP and then the
up or down arrow key then ENTER. The
zero offset will return to the original zero
reading. Note that offsetting the zero
using the tare function can limit the range
of the gauge. Using a 0-100 psi gauge as
an example, if the tare function is exer­cised at 20 psi reading, the maximum
pressure that can be displayed will be
110% of actual full scale (110 psi minus 20
psi offset = 90 psi displayed).

CAUTION: Before disconnecting the
gauge from its pressure source make sure
that the pressure is at zero psi by cancel­ing the tare function as described above.

O

VER-PRESSURE CONDITIONS

The DPG-6700 series gauge has a dis­played range of -14.7 psig (or equivalent)
to 110% of gauge range. If these limits are
exceeded, the low or high out of range
arrows will be displayed and the reading
will remain at the limit indicated above.

NOTE: If tare was used to offset zero, the
max reading will be offset by the zero off­set amount. For an explanation, see
ZERO / TARE section above.

IMPORTANT: The internal pressure trans­ducer in the gauge will withstand a maxi­mum of 2 times the rated pressure without
damage. Burst pressure is 5 times or
25,000 psi, whichever is less. If the over­load rating is exceeded, failure may occur.
Pressure fluctuations may not be dis­played, especially if the filter value is set
for high dampening. Pressure fluctuations
occur in most systems; select the gauge
range with a rating high enough to prevent
overload by peak pressures of pulsations.
It is recommended that a pressure snubber
be used which will reduce the peak pres­sure applied to the gauge. The life of the
gauge will be extended with the use of a
snubber or pulsation dampener.

SELECTING UNITS

A number of pressure units are available
with the DPG-6700 series gauge; the most
common ones are displayed on the LCD.
To select a different unit press the SETUP
key until the display reads “Unit”, use the

▲ or ▼ (up or down) arrow key to scroll

through the displayed available units,
select a unit and press ENTER. To config­ure the gauge for pressure units that are
not on the display, select “SPEC” (special)
and press ENTER. Using the flowchart on
page 10 as a guide, configure the decimal
point location and the low and high values.
The low value will be the pressure value in
the chosen units equivalent to -14.7 psig,
and the high value will be the pressure
value in the chosen units at 110% of gauge
range.

NOTE: The zero and tare offsets are not
adjustable, when using the “special” con­figuration.

MEASURING V

ACUUM

All pressure ranges of the DPG-6700 can
measure vacuum down to -14.7 psig or
equivalent in another unit of measure.
When measuring a pressure less than
ambient barometric conditions, a minus (-)
sign will be displayed. If the input goes
below -14.7 psig, the display will read -

14.7 (or equivalent) and the lower out of
range arrow will be displayed.

NOTE: The accuracy for readings below 0
psi is +/-2% of highest vacuum reading.

ADJUSTING

THE DISPLAY FILTER

The display filter can be used to stabilize
the display reading of a pulsating pressure
input. The filter value is read-out from 1 to
255; 1 being minimum filter value, 255
being maximum filter value. Below are
some typical filter values and their effect
on the display reading. Settling values are
approximate times in seconds to reach
90% of new reading. To set the filter value
press the SETUP key until the display
reads "FILt". Press the ENTER key and
the display will read the previously set filter

value. Use the ▲ or ▼ arrow key to

increase or decrease the filter value and
press ENTER to save the new filter value.

NOTE: The filter values listed are when the
gauge is powered from loop power, when
operating from internal battery power the
filter times will be approximately 7 times
longer.

FILTER VALUE 1 64 128 200
SETTLING, SEC. .5 1 1.3 1.5

FILTER VALUE 210 220 230 240
SETTLING, SEC. 1.8 2.3 3 5

FILTER VALUE 245 247 253 255
SETTLING, SEC. 8.5 11 30 90

LO / HI DETECTION

The DPG-6700 continuously records the
lowest and highest filtered pressure
applied to the gauge. To view the low and
high values, press the SETUP key until the
display reads “LO.HI” and press ENTER.
The display will read the low value record­ed. Press ENTER to read the high value
recorded. The lower half of the bargraph
will display to indicate the reading is the
low value and the upper half of the bar­graph will display to indicate the reading is
the high value. These readings will remain
stored if the gauge is powered down.

NOTE: Values will be lost when battery is
replaced.

RESETTING RECORDED LO / HI
VALUES

To clear the current values, display either
the low or high value and press either the

▲ or ▼ arrow key; the display will show

“Clrd” and the values will begin new low
and high values.

CONFIGURING THE B

ARGRAPH

The bargraph shows the gauge pressure in
a graph form between two points. The
bargraph can be configured to display
pressure in different modes. To reach the
bargraph menu, press the SETUP key until
the display reads “bAr”, the previous con­figuration will be displayed. To change the

type of bargraph, press either the ▲ or ▼

arrow key to scroll between the different
configurations. Upon selecting the desired
bargraph type, press ENTER to save.

"On IIIIII" Bar mode between the

two max points. When this mode is
selected the low point will be 0 psig or
equivalent and the bars will increase to
100% of range.

"On I I I" Single bar between

the two max points. When this mode is
selected the low point will be 0 psig or
equivalent and a single bar will increase
to 100% of range.

"On.HL IIIIII" Bar mode between

two selected points. When this mode is
selected press ENTER and adjust the
low point to the desired value. Press
ENTER and adjust the high point. The
bars will increase from the low point to
the high point.

"On.HL I I I" Single bar between

two selected points. When this mode is
selected press ENTER and adjust the
low point to the desired value. Press
ENTER and adjust the high point. A sin­gle bar will increase from the low point
to the high point.

"OFF" No bargraph displayed.

When selected the bargraph will be off.

CURRENT LOOP

The 4-20 mA current loop allows the user
to output a signal proportional to the pres­sure being measured and displayed. The
nominal range is 4 mA to 20 mA; the maxi­mum range is 3 mA to 25 mA. To config­ure the current loop, press the SETUP key
until the display reads "LOOP" and press
ENTER. The display will read the value for
the previously set 4 mA pressure point in

the previously selected units. Use the ▲
or ▼ arrow key to increase or decrease

the numeric value for the 4 mA point.
Press ENTER and the numeric value for
the 20 mA point will be displayed. Again

use the ▲ or ▼ arrow key to adjust the

desired 20 mA numeric value. Press
ENTER to save the new 4-20 mA configu­ration and return to the normal reading.
The 4-20 mA current loop can be config­ured for reverse action. Simply configure
the 4 mA point with a higher pressure than
the 20 mA value and visa-versa.

NOTE: Output signal goes to zero when
using battery power.

ADJUSTING AND CONFIGURING SET

-

POINTS

There are two individually adjustable and
configurable setpoints which can be set
anywhere within the range of the gauge.
NOTE: The display and setpoints will
remain active with the loss of loop power
(they will be kept active by the internal bat­tery). However if both setpoints are not
used (set to “OFF”), and the power-on­timer is set to something other than zero
and it expires, the gauge will go into power
down mode to extend battery life until a
key is pressed or loop power returns. To
view or configure the setpoints, press the
SETUP key until the display reads “SP.1"
or “SP.2" and press the ENTER key. The
configuration menus are as follows:

LOW, HIGH, LOOP, OFF - Each switch
can individually be set to trip on a high

pressure, a low pressure, on loss of loop
or off. The display will read either “LO”,

“HI”, LOOP or OFF; use the ▲ or ▼ arrow

key to make a selection and press ENTER.
If set for “HI”, the switch will change states
on increasing pressure at the setpoint
value. If set for “LO”, the switch will
change states on decreasing pressure at
the setpoint value. If set for “LOOP”, the
switch will change states on the loss of the
4-20 mA loop voltage/current. If set for
“OFF” the switch will be set to off or open
and will not change states. When set to
off, no further setpoint configurations will
be displayed; the display will show
“SAVE/donE” and return to the normal dis­play screen.

SETPOINT INDICATION - When the set­point indication is set to “On” and a set­point is tripped, the display reading will
alternate between the pressure reading
and a setpoint label. The setpoint labels
are LO.1, LO.2, HI.1, HI.2, LP.1, and LP.2.
If the setpoint indication is set to “OFF”
and a setpoint is tripped, the display will
continuously read the input pressure.
Each setpoint can be individually config­ured to either show an indication or not.

Use the ▲ or ▼ arrow key to select “On”

or “OFF” and press ENTER to save.

NORMALLY OPEN OR NORMALLY
CLOSED - Each switch can be set to nor­mally open “nO” or normally closed “nC”
for the normal or safe state. For example,
if set for normally open and a high set­point, the switch will be open below the
pressure setpoint and close upon increas­ing pressure at the setpoint value. Use the

▲ or ▼ arrow key to select normally open

“nO” or normally closed “nC” and press
ENTER to save.

ADJUSTING SETPOINTS - With the set-

point value displayed, press the ▲ or ▼

arrow key to increase or decrease the
value until the desired trip point for that
switch is reached. Press ENTER to accept
the new value. The new setpoint value will
be saved to nonvolatile memory at the end
of the setpoint menu when the ENTER key

is pressed and the display shows
“SAVE/donE”. Pressing SETUP while in
this menu will cause the display to return
to the normal screen with no changes tak­ing effect.

NOTE: When adjusting the setpoints, the
previous setpoint values are monitored,
and the new value is monitored only at the
end of the setpoint menu when the ENTER
key is pressed and the display reads
SAVE/donE. If no key is pressed for 15
seconds, the display will return to the nor­mal mode and the configuration will revert
back to the previous parameters.

HYSTERESIS - Hysteresis sometimes is
referred to as a deadband value. It is the
numeric value above the low setpoint
value that the switch will clear, and below
the high setpoint value that the switch will
clear. The hysteresis value is displayed in
absolute pressure units that the gauge is
configured for. For example, if a 90 psi
high setpoint with a 10 psi hysteresis is
desired (80 psi release point), set the
"HySt" reset value at 10 psi. The hystere­sis can be individually set for each switch.
Press ENTER and the display will show
"HySt" for one second and then display the
previously set hysteresis value. Use the

▲ or ▼ arrow key to increase or decrease

the hysteresis value and then press
ENTER to save the new value. The hys­teresis value range for a low setpoint is
from the setpoint value up to 110% of full
scale, and for a high setpoint, from the set­point value to absolute zero pressure units.

NOTE: If the hysteresis value is set so
that it cannot be cleared easily by gauge
pressure change, the setpoint can be
cleared manually by going to the setpoint
menu and turning the setpoint off. Make
sure the gauge pressure is below the high
setpoint or above the low setpoint and go
back into the setpoint menu and turn the
setpoint on again. Setting a large hystere­sis value will in effect act like latching out­puts.

POWER ON

TIMER

The power-on-timer is used when the loop
is not powered and the unit is operating of f
of battery power. When received, the
power-on-timer is set to 60 minutes. The
gauge will turn on with any key press and
will remain on for 60 minutes without a key
press. The power-on-timer can be set
anywhere between 1 and 720 minutes (12
hours). If “0" is entered, the gauge will
remain on continuously. To change the
timer, press the SETUP key until the dis­play reads “POt”, press the ENTER key
and the current timer value will be dis-

played. Press the ▲ or ▼ arrow key to

increase or decrease the on time; press
ENTER to save.

NOTE: Both setpoints must be set to
“OFF” for the power-on-timer to be active.

B

ATTERY - LOW INDICATION AND

REPLA

CEMENT

The gauge is designed to give four (4)
years of service life with the supplied, high
energy density, extra long life lithium bat­tery. When the battery needs replacement,
the display will alternate between the pres­sure reading and “L.BAt”. At this time the
gauge will continue to work properly.
When the “L.BAt” indication displays con­tinuously, the battery is exhausted and
must be replaced. Use 1 “C” size 3.6 volt
high energy lithium battery, Tadiran models
TL-5920 or TL-2200 or Saft model
LS26500 or equivalent. See page 17 for
battery replacement instructions.

NOTE: DO NOT use a 1.5 volt “C” size
battery. Such use will void the warranty.

If adjustment is required, we recommend
returning the gauge to the factory. Factory
service offers many benefits. We have the
facilities to provide calibration reports that
include test data at a variety of tempera­tures utilizing NIST traceable standards. In
addition, upgrades may be available to add
or enhance operating features. We
designed the product to last, and we sup­port it so that you can get the most from
your investment.
Although we prefer that you return the
DPG-6700 to 3D instruments for calibra­tion, ordinary adjustments may be per­formed by a qualified person with appropri­ate equipment.

The calibration standard used should have
an accuracy of 0.05% of full scale or bet­ter.

NOTE: Be sure that the units of the cali­brator match the units of the gauge before
performing a calibration.

Calibration may be performed many times
over the life of the gauge. Calibration can
be performed from the front keypad without
disassembling the gauge. To calibrate the
gauge, use a dead weight tester or the 3D
Star Calibrator as the calibration standard.

NOTE: During calibration, the gauge
allows 2 minutes between keystrokes to
change or save a new calibration. If 2
minutes lapse without a keystroke, the
gauge will automatically return to the nor­mal mode without making any changes.
The new calibration information is saved
only if the ENTER key is pressed and the
gauge reads "SAVE/donE".

CALIBRATION PROCEDURE - To cali-

brate the gauge, press and hold the ▲ key

and press the SETUP key until the display
reads "CAL", press ENTER; the display will
read "CAL.L" for the low or zero calibration
value. Adjust the standard for a reading at
zero and press ENTER. After the “bar”

timer expires, use the ▲ or ▼ arrow key to

CALIBRATION

increase or decrease the display reading
to match the reading of the standard and
press ENTER; the display will read
"CAL.H" for the high or span calibration
value. Adjust the standard for a reading at
or near full scale and press ENTER. After

the bar timer expires, use the ▲ or ▼

arrow key to increase or decrease the dis­play reading to match the standard and
press ENTER. The display will read
"SAVE/donE" and return to the normal
reading with the new calibration values
stored in permanent memory.

The DPG-6700 gauge has a feature that
allows a slight adjustment of either the
zero or span values individually. This type
of calibration can be used to "tweak" the
readout to match that of a known value
without actually performing a formal cali­bration procedure.

NOTE: This type of adjustment will invali­date calibration settings resulting from the
procedures in the above section.

ZERO ADJUSTMENT ONLY - To make a
small adjustment on the zero calibration
value of the gauge, enter the calibration
mode, the display reads "CAL", press
ENTER; the display will read "CAL.L" for
the low or zero calibration value. Adjust
the standard for a reading at zero and
press ENTER. After the “bar” timer

expires, use the ▲ or ▼ arrow key to

increase or decrease the display reading
to match the reading of the standard and
press ENTER. The display will read
"CAL.H"; press the SETUP key and the
display will read "SAVE/donE" and will
return to the normal reading with the new
zero calibration value stored in permanent
memory.

SPAN ADJUSTMENT ONLY - To make a
small adjustment on the span point of the
gauge, enter the calibration mode, the dis­play reads "CAL", press ENTER; the dis­play will read "CAL.L". Press the SETUP
key and the display will read "CAL.H" for
the high or span calibration value. With
the standard at the desired span value

press ENTER and after the “bar” timer

expires use the ▲ or ▼ arrow key to

increase or decrease the display reading
to match the standard and press ENTER.
The display will read "SAVE/donE" and will
return to the normal reading with the new
span calibration value stored in permanent
memory.

SELECTING THE DEFAULT CALIBRA­TION - The user can at any time during the
life of the gauge return to the factory cali-

bration values. Press and hold the ▲

arrow key and press the SETUP key until
the display reads "CAL", now press the
SETUP key until the gauge reads “dFLt”.
Press ENTER and the factory calibration
values will be recalled and used for the
calibration of the gauge.
