1.0 GENERAL SAFETY AND WIRING PRECAUTIONS

Review the following safety precautions to avoid injury and prevent damage to

the DE-4000 System or any devices connected to it.

#USE ONLY AS SPECIFIED

To avoid potential hazards, install and use this system only as speciﬁed.

Only qualiﬁed personnel should perform installation, wiring, and conﬁgura-

tion procedures.

#CONNECT AND DISCONNECT PROPERLY

Caution – Do not connect or disconnect equipment, connectors, plugs, etc.,

unless power has been veriﬁed to be off.

#PROPERLY GROUND THE SYSTEM

The ground terminal on the Input Power connector of each module must be

connected to panel ground, which should be the same as engine ground. DO

NOT connect directly to common coil ground.

#SINGLE POINT SYSTEM GROUND

The power supply minus (-) terminal and the ground (GND) terminal are

common. GND must be connected to panel ground. Minus(-) must be con-

nected to power supply minus. Common point is the panel ground which

must be the same as engine ground.

#OBSERVE ALL TERMINAL RATINGS

To avoid damage to the system and personnel, observe all ratings and mark-

ings on the modules. Consult the individual sections of this manual for

further ratings information before making connections to the modules.

#MOUNTING/ENCLOSURE

The DE-4000 System must be mounted in a suitable enclosure.

#POWER AND POWER DISCONNECT

a) Power must be from a Class 2 power source with transient protection or

from a 24-volt battery system.

b) The power to the DE-4000 System must be installed in accordance with

the requirements of the National Electrical Code (US) and the Canadian

Electrical Code (Canada)

c) Over-current power protection is required for the DE-4000 System.

d) A separate disconnect for the DE-4000 System is required. An Altronic

Power Management Module (PMM), a fuse block, or circuit breaker,

must be used from the source power to the DE-4000 in the panel.

e) The power disconnect must be marked as the over-current and discon-

nect for the DE-4000 System.

DE-4000 II

2.0 OVERVIEW

2.1 The DE-4000 is a Control and Safety Shutdown system speciﬁcally designed

to protect, monitor and control critical rotating machinery such as engines or

motor-driven compressors, pumps and generators operating in normal, harsh,

and/or hazardous environments.

2.2 The system uses state-of-the-art microcontrollers and has a multi-level software

architecture. The Controller Module and Terminal Module run a real-time oper-

ating system to ensure that safety and control functions are reliable and deter-

ministic. The Controller Module also contains a System-On-Module (SOM) that

has an embedded web server and also a key-value datastore. The SOM module

ofﬂoads the user interface functionality and also the Modbus communication

to enable the Controller Module and Terminal Module to run real-time without

being affected by connected clients. The system is fully scalable/expandable,

allowing users to incorporate a single control system technology across a wide

range of applications — low, medium, and high-spec.

2.3 The base DE-4000 conﬁguration offers 32 inputs that can be individually con-

ﬁgured for use with switch contacts, thermocouples or analog transducers. The

base system also contains 12 digital and 4 analog (4-20mA) outputs. A maxi-

mized DE-4000 system provides 160 conﬁgurable inputs, 44 digital and 20

analog outputs.

2.4 The Hardware Safety Connection (HSC) is available as a backup safety shut-

down channel to the communications shutdown. The HSC connects the Terminal

Modules to the Controller Module. It is independent hardware that is used as an

independent shutdown signal from any of the terminal modules. When activated

it triggers Discrete Output #1 (typically used as the fuel shutdown) on the Con-

troller Module, independent of the Controller Module’s microcontroller.

2.5 The system is Ethernet-based, including on-board web pages for system con-

ﬁguration (eliminating the need for a separate terminal program), operation,

control applications, and remote monitoring. The intuitive system conﬁguration

web page operates on a “ﬁll-in-the-blanks” basis whereby the application is not

programmed, but conﬁgured. The operator selects the appropriate operating

parameters and setpoints for each input channel, deﬁnes the operation of the

digital and analog control outputs, conﬁgures the service meters, and estab-

lishes the frequency of system datalog sampling and recording.

2.6 A Human Machine Interface (HMI) Display Module is the user interface. The

system being Ethernet-based allows for several Ethernet-based electronic de-

vices to monitor and display information simultaneously. System data can simul-

taneously be displayed on a panel-mounted HMI, a laptop, a handheld display

such as a mobile phone or tablet, as well as remotely.

2.7 System Conﬁguration ﬁles can be created via a laptop or the HMI Display Module,

saved and downloaded, as well as uploaded, to other DE-4000 Systems. This al-

lows for conﬁguration portability for users operating several similar systems.

2.8 Data logs are taken at user-deﬁned intervals and are a compilation of the ana-

log values being monitored by the DE, plus unit speed, status, and complete

information on the ﬁrst fault that caused a system shutdown (identity, value,

date, time). Data log information is stored on a removable microSD card. Data

log information can be retrieved locally or remotely. An integral data analysis/

trending package that is included with the web interface can display and graph

this data for inspection and analysis.

2.9 The system has three main parts:

#HMI Display (Panel Mounted) (691766-1)

#Controller Module (691759-1)

#Terminal Module, 32 channel (691760-1)

These components are interconnected with CAT5e Ethernet cable assemblies

terminated on both ends with an RJ45 connector.

WARNING: Deviation from these

instructions may lead to improper

engine operation which could cause

personal injury to operators or other

nearby personnel.

WARNING: The control and safety

shutdown system must be conﬁgured

prior to use on the machine.

Reference the conﬁguration manual

DE-4000 OCM for instructions

describing how to conﬁgure the

controller for the speciﬁc application.

Verify the conﬁguration prior to

commisioning the machine.

Ethernet Cable, CAT5 1.0m (39") (693221-2)

Ethernet Cable, CAT5 2.0m (79") (693221-3)

2.10 System power requirement is 10-32VDC, 5 amps max.

2.11 Ambient temperature range:

Controller Module and Terminal Module: –40°C to +85°C (–40°F to +185°F)

HMI Display Module: –30°C to +80°C (–22°F to +176°F).

2.12 The DE-4000 System is CSA- and UL-certiﬁed for use in Class I, Division 2,

Groups C and D hazardous locations.

3.0 HMI DISPLAY MODULE (691766-1)

3.1 The HMI Display serves as the user interface for the DE-4000 System. It is a

panel-mounted 8" (diagonal), 1024 x 768 XGA, anti-glare/anti-reﬂective, 4:3

ratio, TFT LCD with PCAP (capacitive-touch) screen and LED backlight. The

front of the display is sealed to IP67 for tough outdoor environments. The dis-

play has a 1000nit max LED intensity with auto or manual backlight dimming.

3.2 The touchscreen HMI Display is web-based and serves as the “Interface” for

conﬁguring the system, as well as the on-sight user display. The HMI commu-

nicates with the Controller Module via a standard CAT5e Ethernet patch cable.

The required Ethernet cable is terminated with an RJ45 connector on each end.

Industrial Ethernet cable assemblies are available from Altronic reference part

numbers 693221-x, “x” represents the length.

3.3 The Ethernet port on the HMI contains two LED indicators; yellow indicates Eth-

ernet activity, green indicates that a communication “link” has been established.

3.4 A 5-key front-mounted, sealed membrane keypad allows for standard, often-

used keys (STOP, RESET, START). The membrane keypad allows these common

keys to be accessible regardless if the screen is viewable. The STOP, RESET,

and START keys are hard-wired to the back of the Display Module. During in-

stallation, these keys are wired to the Controller Module. These connections,

external to the communications cable, allow for reliable hardware connections

independent of the Display Module operation. The remaining two keys are F1

and F2. These keys can be assigned to frequently used functions.

3.5 The HMI Display displays the DE-4000 System conﬁguration and real-time sta-

tus. No programming or conﬁguration data is stored in the HMI Display. All of

the data is communicated to and from—and stored in—non-volatile memory

on the Controller Module. The Controller Module memory retains the current

conﬁguration during normal operation, after compressor shutdown and a system

power-down.

3.6 Front panel dimensions are 9" x 9". Screw mounting dimensions are 6" x 6". The

mounting hardware is 10-24 studs and nuts. The HMI Display is designed to be

mounted into the current Altronic DE Annunciator cutout. This allows for com-

patibility and ease of mounting to previous Altronic systems without the need to

enlarge the panel cutout. Please note, however, that, when retroﬁtting an older

DE-xxxx System Panel Mounted Display Module with the DE-4000 HMI Display

Module, an additional 2" on each side of the original cutout is required.

3.7 The backlight intensity on the HMI is auto-adjusted using a light sensor mount-

ed on the front of the HMI.

3.8 The front glass is made from high quality, damage resistant Gorilla Glass. The Go-

rilla Glass enables the HMI front to be exceptionally tough and damage resistant.

3.9 Input Power requirement to the HMI is 10-32 VDC, 0.8 amp typ. 2 amp max.

3.10 Operating temperature range is -30°C to +80°C (-22°F to 176°F)

3.11 The HMI also contains the following communication ports: RS485, CAN, USB

Host, and USB OTG. These ports are not currently used on the DE-4000 System.

DE-4000 II

4.0 CONTROLLER MODULE (691759-1)

4.1 The Controller Module is the hub of the system. It is the main controller interfacing

with up to ﬁve Terminal Modules, the HMI Display Module, and other systems. The

scalable and expandable nature of the DE-4000 allows it to be used on the simplest

safety-shutdown-oriented applications, on mid-range applications with minimal or

moderate auto-start or capacity control requirements, and on highly-complex units

where a signiﬁcant number of points must be monitored and functions controlled

simultaneously. The Controller Module is designed to be rail mounted.

4.2 The system's communication protocol is Ethernet. The Controller Module con-

nects to the other modules via a standard CAT5e Ethernet patch cable. The

required Ethernet cable is terminated with a RJ45 connector on each end. In-

dustrial Ethernet Cable assemblies are available from Altronic reference part

numbers 693221-x, “x” represents the length. Available Ethernet ports are as

follows:

#5 – Ethernet ports reserved to connect up to 5 Terminal Modules

#1 – Ethernet port reserved to connect to the HMI Display

#1 – Ethernet port reserved to connect to an outside network

4.3 DISCRETE OUTPUTS

The Controller Module has four discrete outputs rated 52VDC, 1.2 amp max.

The discrete outputs provide a means of using the DE-4000 controller to in-

terface with other systems on the engine/motor and compressor. The discrete

outputs are typically used for on/off control of on-engine processes. Typical

applications are: Fuel Valve, Ignition Shutdown, Purge, and Crank Disconnect.

The discrete outputs can be conﬁgured for either shelf state (normally-open)

or failsafe (normally-closed) operation and have an LED indicator associated

with them. If a discrete output is conﬁgured for failsafe (energized for run), the

LED will be ON in the normal run condition and OFF for a fault condition. For

outputs that are conﬁgured for shelf state, the LED will be OFF for normal run

condition and turn ON for a fault condition. The four discrete outputs are opti-

cally isolated, bipolar solid-state switches which are isolated from power supply

minus and engine ground. These outputs can be wired as high-side or low-side

conﬁgurations. The Output Modules are in the open (de-energized) condition

when the unit is not powered.

4.4 DISCRETE INPUTS

There are three discrete inputs; STOP, RESET, START. These inputs can be con-

nected to the hardware keypad on the Altronic HMI Display Module. They also

can be connected to panel-mounted dry contact switches.

4.5 STATE INDICATING LEDS

There are four state-indicating LEDs: RUN state (green), TIMERS ACTIVE state

(yellow), ALARM state (orange), and STOP state (red).

4.6 RS485 PORTS

There are two RS485 serial ports. The RS485 1 port is used for Modbus slave

data, and the RS485 2 port is used for Modbus master data.

4.7 CAN PORT

One CAN port is available and it is marked CANH, and CANL

4.8 USB PORTS

The USB connectors are not to be used in a hazardous area. Assure area is safe

before connecting or disconnecting to the USB connectors.

4.9 INPUT POWER

Input power requirement is 10-32VDC, 0.8 amp typical, 2 amps max. Over-

current protection is provided with an easy to replace 5 amp automotive blade

fuse. The 12-24VDC power for the Controller Module is to be connected to the

INPUT POWER terminals marked (PWR+) and (PWR−); GND is to be grounded

to panel ground. A dual-color green/red diagnostic LED indicates the system

power status. Green indicates that input power is within the systems operating

voltage range. Red indicates that input power is out of the proper operating

range. Off indicates no—or very low—power.

DE-4000 II

4.10 OPERATING TEMPERATURE RANGE

The Controller Module has an operating temperature range of -40°C to +85°C

(-40°F to 185°F)

4.11 WiFi ANTENNA

Antenna cable connection

The WiFi antenna connector on the Controller Module is a 6.35 mm, 50 ohm,

jack style, threaded SMA type RF connector.

Qualiﬁed antenna types

The Wi-FI radio on the DE-4000 is designed to operate with a dipole-type an-

tenna having a maximum gain of 2.14 dBi. Antennas having a gain greater than

2.14 dBi are strictly prohibited for use with the Wi-Fi radio on the Controller.

The required antenna impedance is 50 ohms. Any antenna that is of the same

type and of equal or less directional gain as listed above can be used. To reduce

potential radio interference to other users, the antenna type and its gain should

be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not

more than that permitted for successful communication. Using an antenna of a

different type or gain more than 2.14 dBi is prohibited.

5.0 TERMINAL MODULE (691760-1)

5.1 The Terminal Module is the point of interface between the ﬁeld sensor wiring

and the DE-4000 control system. All sensors enter the system through the

Terminal Module. Control outputs, both analog and digital, are driven from the

Terminal Module. The heart of the Terminal Module is a 32-bit microcontroller.

The operating system runs in real-time to ensure that safety and control func-

tions are reliable and deterministic.The interface to the Control Module is via the

Ethernet cable. A DE-4000 System can contain one, or up to ﬁve each, Terminal

Modules. Each Terminal Module has the following I/O:

#32 – input channels (individually conﬁgurable for use as NO/NC discrete

inputs, J or K thermocouple inputs, or as analog inputs (0-5V or 4-20mA)

#2 – speed inputs (0-10KHz)

#4 – analog outputs (4-20mA)

#8 – high-side or low-side discrete outputs (45V, 2 amp max)

#8 – 5V, 100mA supplies available to power ﬁeld sensors

The DE-4000 operates with industry-standard voltage or current-ampliﬁed out-

put transducers in the range of 0 to 5VDC or 0 to 25mA

5.2 TERMINAL MODULE I/O POINT IDENTIFICATION

Up to ﬁve Terminal Boards can be used in a DE-4000 System. The system uses

a simple Terminal Module/Channel number assignment method that identiﬁes

the Terminal Module and I/O point.

Each Terminal Module is assigned a number from 1 to 5 via the Board ID switch.

Inputs and Outputs for each Terminal Module follow the acronym for each chan-

nel shown on the Terminal Module label. The format is: Terminal Module Num-

ber, a colon, then the I/O point acronym.

Examples:

T2:IN7 = Terminal Module 2, Input 7

T1:AO2 = Terminal Module 1, Analog Output number 2

5.3 BOARD ID SWITCH

The Terminal Modules contain a rotary BOARD ID switch. The BOARD ID switch

is used to identify each Terminal Module connected to the DE-4000 System.

Since each Terminal Module operates identically to each other in the system,

the Board ID switch is used to differentiate each Terminal Module from the oth-

ers. Terminal Module 1 must be set to BOARD ID “1”. Terminal Module 2 must

be set to BOARD ID “2”, etc. Terminal Modules must be assigned in numerical

order starting at BOARD ID 1 to 5. Upon power-up the Controller Module sends

out a signal to “look” to see how many Terminal Modules are connected to the

system and that they each contain a unique ID.

DE-4000 II

Once each terminal module is assigned a “T” number using the board ID switch,

the assigned number can be written with a “Sharpie” marker on each Terminal

Module for identiﬁcation reference. A white box near the board ID switch is

made available as shown at right.

5.4 INPUT CHANNELS

Each input can individually be conﬁgured for use as NO/NC discrete inputs, J

or K thermocouple inputs, or as analog inputs (0-5V or 4-20mA). Each input

contains a corresponding 4-position channel switch that must be set accordingly

for proper operation. Switches are turned ON by moving them to the “ON” posi-

tion (toward the connectors). Please see below for proper switch settings. For

reference, the black part of the switch indicates the "on" position. The analog

switch setting is OFF, OFF, OFF, ON.

The input channels contain overvoltage protection that helps prevent damage

from inadvertent ﬁeld mis-wires. They also contain channel to channel isolation

to prevent one mis-wired channel from affecting other channels.

For analog sensors that require a +5 volt source, the Terminal Module can sup-

ply up to eight +5V sources of current up to 100mA each.

Please refer to ﬁgure 8 for Terminal Module Input Sensor wiring diagrams

N/O and N/C DISCRETE INPUTS

The Terminal Board inputs can accept standard normally-open and normally-

closed dry contacts. The wetting current for sensor detection is supplied inter-

nally by the Terminal Module.

#For a normally-open sensor input, place a shunt jumper between INx+ and

INx- and connect the wire from the sensor to the INx+ input. The other wire

from the N/O sensor is grounded to cause a fault.

#For a normally-closed sensor input, connect one wire from the sensor to

INx+, the other on INx-. The sensor is closed for normal operation and opens

upon a fault.

5.5 J or K THERMOCOUPLE INPUTS

Each Terminal Module can accept industry-standard type J or K thermocouples

on inputs 01–32. Automatic cold junction compensation and linearity correc-

tion are built-in. The units can be conﬁgured for °F, °C, or °K. Both high and

low setpoints are associated with each channel. The system can read type J

thermocouples between -76°F and +1382°F (-60°C and +750°C) and type K

thermocouples between -76°F and +1472°F (-60°C and +800°C). For both J and

K type thermocouples the red insulation color is (-), the other color is the (+).

5.6 INPUTS – PRESSURE TRANSDUCERS

The pressure transducers, Altronic P/N 691201-x and P/N 691204-x, are pack-

aged in a rugged sealed case with an NPT pressure port, a corrosion resistant

media cavity, and a Packard Electric Metri-Pack connector. The ranges available

are 0-100, 300, 500, 1000, 2000, and 5000 PSIG for the 691201-x series

and 0-50,100, 300, 500 PSIA for the 691204-x series, all of which have an

overload rating of 1.5 times full scale without damage. The three wires from the

transducer are: +5 volt excitation, +0.5 to 4.5 volt output, and minus return.

These three wires connect directly to the Terminal Module using cable assembly

P/N 693008-x.

5.7 TEMPERATURE TRANSDUCER

Temperature transducers, Altronic P/N 691202-300, 691203-300, and

691212-450, 691212-450 are packaged in a sealed, stainless steel housing

with a 5/8"-18 UNF threaded body and a Packard Electric Metri-Pack connector.

Temperature transducers 691203/202-300 have a temperature measurement

range of +5 to 300°F. Temperature transducers 691212/213-450 have a tem-

perature range of -40 to +450°F. During conﬁguration, the 691202/203-300

transducers are selected as Deg1 Type; the 691212/213-450 transducers are

selected by choosing Deg2 Type. The three wires from the transducers are: +5

volt excitation, temperature output voltage, and minus return. These wires con-

nect directly to the Terminal Module using cable assembly P/N 693008-x.

5.8 INPUTS – DIFFERENTIAL MEASUREMENTS

Differential pressures or temperatures may be measured by using two consecu-

tive channels. The transducers used to measure differential values must be

of the exact same type and range. The ﬁrst channel of the pair displays the

basic parameter it is monitoring and the second channel of the pair displays

the numeric difference in engineering units of its value subtracted from the ﬁrst

channel’s value. Setpoints for each channel monitor the displayed value of that

channel. The second channel setpoints monitor the differential value.

5.9 4-20mA INPUTS

The Terminal Module can accept 4-20mA inputs by selecting the internally-con-

nected 200-ohm resistors (via the channel DIP switch), creating a termination

voltage of 0.8 to 4.0 volts. The shunt jumper wire between the + and – terminals

for that channel must be connected for proper 4-20mA operation.

5.10 +5V TRANSDUCER SUPPLY

For convenience there are eight total 5V supplies rated at 100mA each for the

purpose of supplying 5 volts DC to transducers. The 5V supplies are protected

from shorts and reverse connection. The 5V supply contains a unique low for-

ward voltage transistor that allows the output to be a tighter tolerance and to

survive shorts and ﬁeld mis-wires.

5.11 SPEED INPUTS

Each Terminal Module contains two speed inputs. Each speed input can be

conﬁgured independently from the other. Examples of monitored speed inputs

are engine RPM and turbo speed RPM.

Typical speed signals can come from magnetic pickups or Hall effect pickups

monitoring the engine ﬂywheel or other rotating gears. The monitored gear can

be of some ratio to the speed of interest (the speed conﬁguration page is used

to select a ratio of gear teeth to speed of interest). The frequency range of the

speed input is 0 to 100KHz. Nominal input voltage levels are 5 to 24 volts. Each

speed input is protected from mis-wires of up to 200 volts max.

The RPMx- terminals are common to DC-. Connect the speed input to the ter-

minals marked RPMx+ and RPMx-. Altronic magnetic pickups or Hall effect

pickups are typical sources for RPM measurement.

#MAGNETIC PICKUP — Connect the two wires from the 691118 series or

similar magnetic pickup to the Module at terminals RPMx+ and RPMx- using

cable assembly 693104 series.

#HALL EFFECT PICKUP — Connect the three wires from the 791050 series

Hall effect pickup to the module at terminals RPMx+, RPMx-, and a +5 volt

source using cable assembly 593050 series. Connect pickup cable wire B to

a +5V supply, wire A to terminal RPMx+ (plus), and wire C to terminal RPMx-

(minus). In addition, a 10,000-ohm pull-up resistor must be placed across

the +5V supply to GT of the monitor. Refer to the wiring diagrams for hookup

details.

5.12 ANALOG OUTPUTS

Each Terminal Module provides four 4-20mA analog outputs. The analog out-

puts can be used for interfacing to actuators, I/P Transducers, governors, and

other control hardware. These 4-20mA outputs are typically used to implement

control strategies. For further information on typical control strategies, refer to
