INSTALLATION
Installation should be performed only by qualified
personnel, and in accordance with local governing
regulations.
GENERAL INFORMATION
This manual will assist you in operating and maintaining
the GPI electronics supplied with your GPI meter or as an
accessory unit on both local and remote models. The GPI
Electronics can be used in indoor or outdoor applications
where occasional exposure to moisture is common.
 • ThePulseOutwithDisplayisavailableintwoversions.

the positive displacement GM Series oval gear meters.
 • ThePulseOutwithDisplaycanbebatterypoweredor
externally powered.
Product differences in this manual are identified by either,
Local or Remote as necessary.
The Display may come calibrated from the factory for gal-
lons “GAL” and litre “LTR” and be locked out “PRESET” to
prevent unwanted calibrations. Field calibrations are available
on “CAL B” and “CAL C.”
If the unit was purchased as an accessory or remote, the
calibration has not been entered and the end user will be re-
quired to calibrate the display. The gallon and litre calibration
may then be locked out using the configuration procedure.
To determine if the Pulse Out with Display has been configured
and calibrated at the factory to your specific meter, view the
display. If “GAL” is followed by the word “PRESET,” it has
been configured and calibrated. If “GAL” is not followed by
the word “PRESET,” the display must be calibrated.

Some products come with 20 feet of shielded cable. GPI offers
an optional cable kit with 100 feet of cable (see spare parts
list). When wiring longer lengths of cable, be sure to connect
the shield to LOCAL-COM only! (Multiple shield connections
may cause ground-loop problems. Some trial and error may
be needed because of the wide variety of user conditions.
Try to keep cable lengths short. Individual installation sites
vary widely, contact GPI Customer Service with questions
regarding your specific needs.
This manual refers to various models of GPI flowmeters.
Determine what type of input the electronics will receive and
what type of output, if any, you require. If the unit is not already
wired, use the diagrams found in the wiring diagrams section
to correctly wire the system.
Connecting the Equipment
1. Remove the faceplate by removing the four corner
screws.
2. Attach wiring from your equipment according to the
following terminal connections and wiring instructions,
depending on your circumstances. (See Terminal Con-
nections below)
The display may be powered by battery, externally powered
or both. When both are used (external power terminal as
primary with the battery terminal as back up) the batteries
should last up to 5 years. Connection and disconnection of
either power input, while the other is active will not interrupt
operation of the display.
Determine maximum power supply voltage after de-
termining maximum allowable voltage of all electronic
devices in the system.

The calibration and display features may have been pro-
grammed at the factory, indicated by the word “PRESET”
on the display (see Display 1), and further user programming
is not required. If the unit was purchased as an accessory,
remote or as a spare part, the calibration features will not be
appropriate for the user installation and must be calibrated
before use. If desired, the display features can be changed
in the field.

Configuration determines what information is present on the
LCD display. For instance, total, flowrate, number of decimal
places, number of calibration curves, etc.
The Display has been programmed with many features, which
can be enabled by the end user through the configuration
process. By disabling unnecessary features, day-to-day
flowmeter operation can be greatly simplified, making the
unit easier to use. Alternately, there are several features not
found in the default configuration.
Available features include:

Changing Configuration Settings
Access to the configuration settings require a specific pro-
cedure and a pin code available through the GPI website at
www.gpi.net or call GPI Customer Serivce at 888-996-3837.
All non-PRESET displays must be calibrated before
use!
CONFIGURATION
About Calibration
Calibration determines that the information presented
matches your particular meter. For instance, the “S20N” 2
inch turbine has approximately 100 pulses per US gallon
whereas the “GM020” 2 inch oval gear meter has 25.3 pulses
per US gallon. The display must be calibrated for correct and
accurate display information.
To determine if the Pulse Out with Display has been configured
and calibrated at the factory to your specific meter, view the
display. If “GAL” is followed by the word “PRESET,” it has
been configured and calibrated. If “GAL” is not followed by
the word “PRESET,” the display must be calibrated.
WARNING
All operations are reflected in the LCD readout. The top line
identifies the calibration curve. The middle line reflects flow
information. The bottom line shows information from the
totalizer.Wordsor“ags”displayonthetopandbottomline
to further identify specific information.
NOTE: Operations can be practiced prior to installation. To
simulate flow conditions, blow gently through the meter.
Turn On
The unit is on when any display is present. It turns on auto-
matically when liquid flows through the meter. It can be turned
on manually by pressing and releasing the DISPLAY button.
Turn Off
Whenever no flow has been sensed for one minute, the unit
automatically switches to a power-saving “sleep” mode with
a blank display. The unit will automatically “wake up” the
moment any flow is sensed and will remain awake as long
as fluid is flowing. Totals are never lost during sleep periods.
Batch and Cumulative Totals
Total flags are displayed on the bottom line. The Cumula-
tive Total (labeled TOTAL 1 LOCKED) is the total of all fluid
measured since the meter’s power was connected. (At your
rstuse,theCumulativeTotalmaynotreadzerobecauseof

Flowrate Mode
The Rate of Flow feature is accessed by briefly pressing and
releasing the DISPLAY button as described above. When this
feature is activated, the word “FLOWRATE” displays to the
left on the bottom line (See Display 3) and the numbers in the
middle of the display reflect the rate of flow (instead of total).
Units are set to update the display every 5 seconds, so the
first reading after flow starts or changes and the last reading
after flow stops or changes will not be correct. This is normal.
Changing Display Registers
TochangetoanothertotalizerregisterortoFLOWRATEmode
during normal operation, watch the bottom line display flags
while you briefly press and release the DISPLAY button. When
you press and release the display buttons, the mode will ad-
vance as follows: TOTAL 1 LOCKED (Cumulative Total), TOTAL
2 (Batch Total), FLOWRATE, TOTAL 1 LOCKED (etc.). You can
change registers at any time, even during flow. Non-visible
totalizerregisterswillcontinuetoaccumulate.
NOTE: Generally, display registers change when the buttons
are released.
Calibration Curves
The GPI electronics have enhanced calibration features. All
calibration information is visible to the user as words in the
upper part of the display, above the numeric digits.
The calibration curve(s) may be set by the user, and can be
changed or modified at any time using the calibration pro-
cedure described below in the CALIBRATION section. Totals
or flowrate derived from the field calibration are visible when
the field calibration setting is selected.
Selecting a Different Calibration Setting
You can switch between GAL and LTR modes at will without
“corrupting”totalizercontents.Forexample,thecomputer
cantotalize10.00gallons.IftheuserswitchestoLTRmode,
the display will immediately change to “37.85” (the same
amount in units of litres). GAL / LTR switching also works in
FLOWRATE mode.
To select a different calibration setting, first press and hold
the CALIBRATE button. Continue to hold it while also briefly
pressing and releasing the DISPLAY button (you may then
also release the CALIBRATE button). The flag indicators in
the upper area of the display will change to show the newly
selected calibration setting. Calibration settings change in this
order: GAL, LTR, CAL B, CAL C, GAL, etc. While fluid is flow-
ing only the GAL and LTR selections may be made, however,
when NO fluid flow is occurring, any setting may be selected.
Propeller
A small propeller displays to indicate liquid is flowing through
the meter.

The GPI electronics allows for “field” calibration, that is,
user entry of custom calibration parameters. A “single point”
calibration may be used on the GPI GM series, or any other
positive displacement meter, with excellent results. Any pulse
generating device that changes K-factor with varying flowrate
(turbine meter, paddlewheel, etc.) should be calibrated to at
least three points throughout the anticipated flow range for
best accuracy. Up to 15 points can now be entered. The use
of dependable, accurate calibration equipment is highly rec-
ommended for the most accurate results. Additionally, each
curve can be calibrated to a different fluid.
The display will have either a K-factor Entry or a Dispense/
Display Field Calibration. If you need to switch from one kind of
calibration to another, please see CONFIGURATION section.
The K-factor of your meter is usually located on the housing
or nameplate of the meter body. It will also appear on the
Calibration report. Or call GPI Customer Service at 888-996-
3837 for assistance.
The litre calibration is determined using the gallon calibration
information. Enter the K-factor as pulse per gallon in the GAL
curve. This will correctly calibrate the LTR PRESET curve. You
may still remove the GAL indication on the display using the
computer electronics configuration procedure.
