1.0 OVERVIEW
1.1 This manual applies to GPN1000 and GPN1000-12 panels used with Series
25-A, 50-A, 65-A, and 65-B (formerly Series A-A, I-A, II, and III-A) kits used
on in-line or small V-engines. For help locating subjects in this document see
p a g e 17.
1.2 The control system panel GPN1000 consists of two main parts packaged in
an industrial enclosure: Display Module DE-1510 and Power/Terminal Module
691142-2. Interconnecting cable 693115-1 connects Module DE-1510 to
Module 691142-2. The GPN1000 is for 24V systems, and the GPN1000-12 is
for 12V systems.
1.3 The Altronic DE-1510 controller system is a dedicated electronic microprocessor-
based system designed to sense specific analog and digital input points to
control and monitor the GTI Bi-Fuel® natural gas fumigation system for diesel
engines. The system is configurable for various applications using a PC (personal
computer) and the supplied DE-1510 terminal program and contains a non-volatile
memory to store the setup. Serial communications provide an interface to PC’s,
PLC’s, modems and satellite uplinks for remote communication if desired. A
backlit 4x20 LCD character display shows system status, programmed controller
parameters and channel labels. A front mounted keypad serves as the user
interface. The DE-1510 provides for the natural gas fueling off/on control function
and for an optional closed loop automatic control function to optimize the amount
of natural gas substitution of diesel fuel under varying modes of operation.
Additionally, the DE-1510 provides for remote data acquisition and supervisory
control in a compact, low cost package dedicated to natural gas fuel substitution
on industrial diesel engine applications.
2.0 DE-1510 DISPLAY MODULE
2.1 The Display Module serves as the user interface for the DE-1510 system.
Packaged in a 6.5" x 6.5" panel mounted enclosure, it consists of an
alphanumeric 20-character x 4-line backlit LCD display, a 16-key front-mounted
keypad, DB-25 D-Sub and DB-9 D-Sub connectors and three pairs of serial port
indicators.
2.2 The keypad is a sealed membrane unit containing the STOP and RESET keys
and other keys used to navigate through channel status, description, view
screens, and to edit the setpoints.
2.3 The LCD has a home screen that displays a status line, BI-FUEL OFF or ON,
gas supply pressure (GSP), manifold air pressure (MAP1) and manifold air
temperature (MAT1). Pressing the VIEW CHANNEL key displays the channel
number, its timer status, analog value (if applicable) and the user label.
2.4 The keypad, along with the LCD display, are used to navigate through channel
status and descriptions, view screens, and to view or edit the system’s
configuration. The ↑UNITS or ↓UNITS or the →TENS or ←TENS keys are used
to access channels by increasing or decreasing the channel numbers by one or
by ten with each key press. Pressing the NEXT key advances the display to the
next screen or item. All menu adjustments are saved in non-volatile EEPROM
memory by pressing the ENTER key. The EEPROM memory retains the current
configuration during normal operation, after engine shutdown and at system
power-down.
2.5 Three pairs of LED’s are provided on the back of the Display Module for
troubleshooting purposes, one Receive (RX) and one Transmit (TX) LED for
each port. The TX LED will flash when the Display Module is transmitting serial
communications on the labeled port. The RX LED will flash when the Display
Module is receiving serial communications on the labeled port.
WARNING: DEVIATION FROM THESE
INSTRUCTIONS MAY LEAD TO
IMPROPER ENGINE OPERATION WHICH
COULD CAUSE PERSONAL INJURY
TO OPERATORS OR OTHER NEARBY
PERSONNEL.
NOTE: If possible, keep the original
shipping container. If future
transportation or storage of the
controller is necessary, this container
will provide the optimum protection.

3.0 POWER/TERMINAL MODULE
3.1 The Power/Terminal Module is rail mounted and is the interface to the DE-
1510 Display Module and to other systems. It also is the point of interface
between the field sensor wiring terminal strip and the DE-1510 control system.
A removable dual terminal strip is used for the connection of the system. The
equipment mounted discrete sensors may consist of up to 4 normally-open or
normally-closed switches as well as 8 analog transducers. The 4 discrete sensor
inputs are numbered 10-13. The 8 analog inputs are numbered 20-27.
3.2 The Power/Terminal Module has six solid state output switches. The output
switches provide a means of using the DE-1510 controller system status to
operate relays and the fuel solenoid valve. The output switches will be in the
open (de-energized) condition when the unit is unpowered. If 24 Vdc is lost
to the DE-1510 system, the output switches will go to an open state. Output
switches 3 and 4 function as normally-closed contacts to permit the Bi-Fuel
solenoid valve to turn on. If supply voltage is lost, the LED’s will be ON in the
normal Bi-Fuel ON condition and OFF for a Bi-Fuel OFF or fault condition.
Output 5 functions as a driver for the FAULT LED on the front of the panel and
will normally be off.
3.3 The input power of the DE-1510 system is applied to the power supply terminals
marked (+) and (–) PWR. A 6.3 amp, replaceable slow-blow fuse protects the
system from over currents, and a power LED lights when power is applied to the
system.
4.0 MOUNTING THE PANEL (FIG. 1)
4.1 Mount the control panel(s) to a post or to a suitable flat surface so that the
display is at a convenient viewing height.
5.0 WIRING (SEE WIRING DIAGRAMS: FIGS. 2, 3 & 4)
5.1 SYSTEM COMPONENT WIRING (FIG. 2)
Three individual wiring harnesses are provided in the system kits. Each wiring
harness, or bundle, consists of functionally-grouped connections to sensors
or actuators, which would normally be located in the same general area. Each
bundle is marked as Engine Harness, Fuel Harness, or Power Harness. The
wiring is protected by a flexible plastic tubing. Each wiring bundle is provided
with a bulkhead fitting installed. Mount the bulkhead fittings into the holes
provided in the bottom of the panel. When routing the wiring, it is essential that
the following practices be adhered to:
Never run sensor wires in the same conduit with high energy
wiring such as the AC line power.
Keep high voltage wiring at least eight inches (200mm) away from
sensor and sensor wiring.
If it becomes necessary to check sensor to panel wiring with an
ohmmeter or other powered means, first DISCONNECT the plug-in
terminal strips from the Terminal Module. Applying voltage to the DE-
1510 system through the sensor leads may damage the device.
5.2 ENGINE (ORANGE) HARNESS WIRING (FIG. 3)
A. Mount the pressure sensors provided in the accessory kit to the engine
in a manifold or tube from the engine. Depending upon the specific
application, there may be unused wires in the bundle. Plug in the mating
connectors; VAC1 is the air cleaner vacuum and MAP1 is the MANIFOLD
AIR PRESSURE.
NOTE: Avoid mounting the GPN1000
panel with the LCD display facing
direct sunlight. The display operating
temperature range is −31°F to +176°F
(−35°C to +80°C). The panel should
be mounted within 10 ft. (GPA0005-
10), 20 ft. (GPA0005-20), or 30 ft.
(GPA0001-30) of the engine, the
fuel solenoid valve and fuel pressure
regulator.
NOTE: All furnished drawings and
instructions assume (–) ground DC
system. In the case of a floating
ground, or (+) ground DC system,
please contact Altronic Factory for
support.
NOTE: Do not expose the pressure
transducer to temperatures above
221°F. (105°C).

B. Mount the thermocouples to the engine, routing the thermocouple wires as
required. To accommodate the differences in location of the sensors, remove
the individual wires from the plastic tubing, as required, and tape the tubing
closed after proper length to reach the sensor location is known. MAT1
is the MANIFOLD AIR TEMPERATURE and EGT1 is the EXHAUST GAS
TEMPERATURE.
C. If the optional vibration sensor is used, mount as indicated and connect to
the wires marked VIB+ and VIB1 (signal to panel).
D. At the panel end, adjust the length of the bundle, if required, and mount the
bulkhead fitting through the far left hole, viewing the panel from the front.
Terminate the wires to the customer connection terminal strip. Each wire is
marked with the same identifier as the terminal strip; connect these to match.
5.3 FUEL (BLUE) HARNESS WIRING (FIG. 3)
The FUEL HARNESS contains the wiring to the fuel supply and pressure
regulator and is not to be routed to the engine.
A. After mounting the FUEL GAS SOLENOID VALVE, connect the SOL+ and
SOL- wires to the solenoid coil.
B. Connect the ROP wires to the REGULATOR OUTPUT PRESSURE switch
terminals. Do not connect the shield wire, as it is terminated at the panel
end only.
Note: The GPN1000-12 panel does not utilize the ROP input.
C. Mount the GAS SUPPLY pressure transducer GSP and plug in the connector.
D. At the panel end, adjust the length of the bundle, if required, and mount the
bulkhead fitting through the third from the left hole viewing the panel from
the front. Terminate the wires to the customer connection terminal strip.
Each wire is marked with the same identifier as the terminal strip; connect
these to match.
5.4 POWER (RED) HARNESS WIRING (FIG. 3)
The POWER HARNESS contains the power wiring for the panel.
A. GPN1000
Connect the supply power wires to the 24 Vdc input power terminals on
the power supply, plus to terminal (+) and minus to terminal (−); power
requirement is 24 Vdc, 120 watts max. The DC− terminal will be connected
to the panel ground which must be the same as engine chassis ground.
GPN1000-12
Connect the supply power wires to the 12 Vdc input power terminals on
the power supply, plus to terminal (+) and minus to terminal (−); power
requirement is 12 Vdc, 180 watts max. The DC− terminal will be connected
to the panel ground which must be the same as engine chassis ground.
B. At the panel end adjust the length of the bundle, if required, and mount the
bulkhead fitting through the far right hole viewing the panel from the front.
Terminate the wires to the customer connection terminal strip. Each wire is
marked with the same identifier as the terminal strip; connect these to match.

7.0 UNDERSTANDING THE HOME SCREENS
7.1 The “home screens” are described as a series of screens used to display several
of the most critical operating parameters on one screen. All of the home screens
provide a status word on the upper line.
The status line will read one of the following:
BI-FUEL ON
BI-FUEL OFF
BI-FUEL INHIB
TIMERS ACTIVE
CHECKING INPUTS
FAULT AL1
MANUAL STOP
The LCD display always reverts to one of the home screens after a keypad
operation is completed or the operation times out.
7.2 To activate the Bi-Fuel system, turn on the power; the unit automatically resets.
If no system faults are detected during the CHECKING INPUTS scan, the home
screen will display the TIMERS ACTIVE message until the programmed fuel
delay timer expires. After the time delay is completed, the home screen will
display either the BI-FUEL ON or BI-FUEL OFF status according to the current
conditions and the programmed control values. The RESETTING message will
be displayed momentarily followed by TIMERS ACTIVE, and the home screen
will then re-appear.

7.3 The DE-1510 controller continuously monitors the system for two different levels
of setpoints. The first group are called control setpoints and, when violated, they
cause the Bi-Fuel function to be temporarily suspended (engine reverts to 100%
diesel operation) until conditions change. The violation of these setpoints may
occur readily in normal operation of the engine and the system does not require
any USER intervention to begin re-supplying natural gas when these clear, after
the bi-fuel delay expires.

A temporary Bi-Fuel Inhibit can be implemented when desired, by opening the
jumper connection between the terminals for input 13. This input prevents
output #4 from turning on, which prevents Bi-Fuel operation. Bi-Fuel operation
may begin after input 13 is no longer actuated.
7.4 The safety shutdowns are the second level of monitored setpoints. When any of
these setpoints are violated even momentarily, the Bi-Fuel will stop supplying
natural gas (engine reverts to 100% diesel operation) and will NOT begin re-
supplying gas, until a USER initiated RESET is received. When one of the safety
shutdown setpoints has been violated, the gas solenoid valve is closed, and the
FAULT message for the first faulted channel will appear on the display and will
remain until it is acknowledged by a RESET. The number 1, after AL (alarm),
shows the output switch that is faulted. If all of the faulted sensors have been
cleared and the RESET key is pressed, the class B and output timers will reset
and the display will repeat the sequence of section 7.2.

10.0 CONTRAST RATIO ADJUSTMENT
10.1 The LCD contrast ratio is adjusted for optimum contrast over a large temperature
range at the factory. It may be necessary to make slight adjustments to the LCD
contrast ratio because of aging and or extreme temperature changes. The contrast
ratio potentiometer (TP1) is located on the back of the Display Module. Use an
adjusting tool and turn the potentiometer clockwise to lighten the contrast ratio or
counterclockwise to darken the contrast ratio.
To set the potentiometer back to the factory setting: with the Display Module
at an ambient temperature of approximately 65°F to 77°F (18°C to 25°C), turn
the potentiometer clockwise until the display contrast ratio is almost too light
to read. Turn the potentiometer counterclockwise 3 to 3-½ turns. The display
should then be at a desirable contrast ratio.
11.0 DATA LOGGING AND COMMUNICATION OPTIONS
11.1 The DE-1510 controller system contains a data logging feature. Data logging
collects information from the system and keeps track of, or logs, that
information over a period of time. That data is then available through a PC or
PLC at port 1 (the RS-232 port) or port 3 (the RS-485 port).
11.2 NODE NUMBER
The node number is the address of the controller being contacted. This number
is programmed by the terminal program and can be viewed or edited in the
menu screen. A two digit number from 01 to 99 can be used.
11.3 COMMUNICATIONS PARAMETERS
The following must be set in the PC or PLC to communicate with the controller
system:
Baud Rate: 9600
Data Bits: 8
Stop Bits: 1
Parity: None
11.4 The data logging memory can retain a total of 100 records before writing over
the oldest information. The most current data is always record number one; the
next most current is number two, etc. The oldest information, record 100, is
lost when a new record is written. The logging period is set for 1 minute.
A new record is also written when a first fault occurs. If the first fault occurs
between the logging period, the first fault record will be record number one and
the next scheduled record will be number two.

11.5 Refer to files on the DE-1510 CD-ROM for more information on serial
communication specifications. This document contains in depth information on
MODBUS, ASCII, ROI (Remote Operator Interface), data logging, and dial in/out
features.
12.0 PROGRAMMING THE DE-1510
12.1 The DE-1510 terminal program operates from a standard PC and permits the
operator to configure the system. There is a monitor mode that the operator can
use to monitor an existing installation and access system data. This data can be
accessed locally or remotely via a modem.
The following user-supplied hardware is required:
Computer: IBM-compatible PC, Windows 95/98/ME/XP, hard drive (10 MB of
free disk space required), CD-ROM drive, SVGA graphics (800X600 or greater
preferred) with color monitor.
Serial Port: RS-232 port for programming.
Modem: 9600 baud (or greater) modem required.
12.2 The terminal program installs from a CD-ROM drive. A minimum of 10MB of
free disk space is required. Additional disk space will be required if the remote
data log database function is used. The space required will be dependent on the
size of the working database.
Insert the CD-ROM disk into the CD-ROM drive and run the setup.exe file. If you
have the autorun selection enabled on your CD-ROM drive, the install program
will run automatically. The install program will prompt you for a destination
folder where the program will be installed. After the install completes, you can
run the program from the Windows Start button, Programs Menu, Altronic DE-
1510 system. Select the DE-1510 menu selection.
12.3 Connect the computer cable from the computer to the DB9 connector Port #1
on the back of the DE-1510 display.
12.4 CONFIGURE KEY
The DE-1510 needs to be initially programmed using the DE-1510 Terminal
program. Select the items for download which best fit the intended application.
12.5 EDIT SETPOINTS KEY
The setpoints of the DE-1510 may be changed from the computer by selecting
this key.
12.6 MONITOR KEY
This feature allows the user to retrieve data logged messages which are typically
used for PC monitoring or SCADA/PLC systems. The connections can use either
a modem or connected directly into the comm. Port. Data logs may be retrieved
into a standard EXCEL file format.
The following keys are applicable during the monitor function:
CONNECT KEY
This feature selects how the PC is going to connect to the DE-1510. Select
either a comm port or a telephone number for a modem.
HANGUP KEY
This disconnects the PC from the port or the modem.
DATALOGS KEY
This feature allows for retrieval of data logged messages in the PC. Data logs
may be retrieved into a standard EXCEL file format.

AUTO START KEY
This feature allows for serial communications to STOP Bi-Fuel operation or
RESET Bi-Fuel operation.
VIEW DATABASE / CHART DATABASE KEY
These powerful tools allow users to display and chart the data logged
information.
12.7 CALIBRATE KEY
This allows the user to calibrate analog sensor channels. Press this button and
select the channel to be calibrated. The sensor selection box will show the
default values or the last values calibrated. The CURRENT DATA box shows
the value being displayed by the DE-1510. On the terminals of the channel
being calibrated, connect a voltmeter between the input (+ and –) to measure
the output voltage of the transducer. Apply the desired minimum pressure,
temperature, vibration, position or KW input to the transducer being calibrated.
Now measure the voltage using the voltmeter on the terminal strip. Enter
this voltage into the LOW SENSOR VOLTAGE box on the PC screen. Click the
ACCEPT button to make this the new calibration value. The CURRENT DATA box
will now read the desired minimum value. If the span is to be adjusted, increase
the input to the transducer to the desired high value. Measure the voltage at
the terminal strip using the voltmeter and enter the measured voltage in the
HIGH SENSOR VOLTAGE box and hit the ACCEPT button. The calibration of the
channel is now complete.
12.8 EXIT KEY
Exits the DE-1510 PC Terminal program.
