1.0 OVERVIEW
1.1 For help locating subjects in this document, a section index is provided on page 37.
1.2 The Altronic DE-2200 compressor monitor system is an electronic microprocessor-based
systemdesignedtosensevariousanalogsensors,digitalswitchesandindustrystandardtype
J or K thermocouples to monitor industrial compressors. The system is field-programmable
using a PC (personal computer) and the supplied DE-2200 terminal program and contains a
non-volatile memory to store the setup. Serial communications provide an interface to PC’s,
PLC’s,modemsandsatelliteuplinksforremotecommunication. Abacklit4x20LCDcharacter
display shows system status, programmed engine/motor and compressor parameters and
channel labels. Afront mountedkeypad servesas theuser interface. TheDE-2200 provides
the safety shutdown functions needed to prevent unnecessary damage to remote operated
equipment. Additionally, the DE-2200 provides for remote data acquisition in a compact, low
cost package dedicated to industrial compressor applications.
1.3 Thesystemconsistsof threemainparts: apanelmountedDisplayModuleDE-2200,aPower
Supply Module 691122-1, and a Terminal Module 691136-1. These components are
interconnected by means of Cable assembly 693115-1.
WARNING: THE MONITOR SYSTEM MUST BE CONFIGURED PRIOR TO USE ON A
COMPRESSOR SYSTEM. REFERENCE DE-2200 PI PROGRAMMING
INSTRUCTIONS, FOR INSTRUCTIONS DESCRIBING HOW TO CONFIGURE THE
MONITOR FOR THE SPECIFIC APPLICATION. VERIFY THE PROGRAM IN
NONVOLATILE MEMORY (THE EEPROM) PRIOR TO STARTING THE SYSTEM.
REFER TO SECTION 10.0 ON HOW TO VIEW THE CURRENT CONFIGURATION.
2.0 DISPLAY MODULE
2.1 The Display Module serves as the user interface for the DE-2200 system. It is in a 6.5" x 6.5"
panel mounted enclosure and consists of an alphanumeric 20-character x 4-line backlit LCD
display,a16-key front-mountedkeypad,DB-25 D-SubandDB-9 D-Subconnectorsand three
pairs of serial port indicators.
2.2 The keypad is a sealed membrane unit that contains the familiar STOP, RESET and TEST
keys as well as other keys used to navigate through channel status and description, view
process screens, and to edit the configuration.
2.3 The LCD displays a “home screen” that displays a status line along with three user
configurable analog points; typical points are speed, the suction pressure and the discharge
pressure. A “view screen”, which is available by pressing the VIEW key, displays up to eight
user configurable analog process labels, values and bargraphs of the corresponding analog
inputs. Pressing the VIEW CHANNEL key displays the channel number, its timer status,
analog value (if applicable) and the corresponding 20-character user defined label.

-2-
2.4 The keypad, along with the LCD display, are used to navigate through channel status and
descriptions, view process screens, and to view or edit the system’s configuration. The
8UNITS or 9UNITS or the 6TENS or 7TENS keys areused to access channels by increasing
ordecreasing the channelnumbers by oneor by tenwitheachkeypress. PressingtheNEXT
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 compressor shutdown and a 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 eachport. TheTX LED will flash
when the Display Module is transmitting serial communications on the labeled port. The RX
LEDwillflashwhentheDisplayModuleisreceivingserialcommunicationsonthelabeledport.
3.0 POWER SUPPLY MODULE
3.1 The Power Supply Module is made to be rail mounted and is the interface between the
Terminal and Display Modules and to other systems. It typically plugs directly into the
Terminal Module using the DB-25 connectors and is held together with screws and screw
locks.
3.2 The Power Supply Module is made to accept up to four industry standard commercially
available0.6 inch plug-inOutput Modules. The OutputModulesprovide ameansof usingthe
DE-2200 monitor safety shutdown system status to interface with other systems on the
engine/motor and compressor. A typical application would be as a relay or solenoid coil
driver. TheOutputModules areoptically isolatedsolid-state switcheswhich areisolated from
power supply minus and engine ground. The Output Modules will be in the open (de-
energized) condition when the unit is unpowered. The output modules can be software
configuredforeithernormallyopen(N/O)ornormallyclosed(N/C)operationandhaveanLED
indicator associated with them. Outputs 3 and 4 are for use with the optional speed switch
and pre/post-lube features respectively. If an Output Module is programmed for normally
closed (energized for run), the LED will be ON in the normal run condition and OFF for a fault
condition. For Normally open configured modules the LED will be OFF for normal run
condition and turn ON for a fault condition.
The standard Output Modules’ outputs use the top row of the dual 16-position terminal strip
which is marked OUT 1 through OUT 4. Each of these outputs are fused with a replaceable
6.3 amp slow-blow fuse, Altronic P/N 601653. In addition to accepting industry standard
OutputModules,acustom AltronicOutputModuleP/N691124isavailablefortrippingignition
powered CD fuel valves and shorting CD ignition shutdown leads upon a fault. When both
functions are required, two of these modules are used as follows: OUT 1 slot must be used
to trip the fuel valve, and OUT 2 slot must be used to short the ignition. If 12-24 Vdc is lost
to the DE-2200 annunciator system, the custom Output Modules will trip the fuel valve and
short the ignition shutdown lead. This mimics the “fail-safe” operation of a normally closed
Output Module and therefore the LED will be ON in the normal run condition and OFF for a
fault condition. In programming the system, these modules are identified by using the
IGN/FUEL selection. Terminals IGN+ and IGN!are used to connect the shutdown lead, and
FV1 and FV2 are used for the CD fuel valve. A capacitor is included in the Power Supply
Module to supply the energy to trip the fuel valve.
3.3 The12-24VdcpowerfortheDE-2200systemisappliedtothepowersupplyterminalsmarked
(+) and (!) 12 - 24 VDC INPUT POWER. 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.

-3-
3.4 The external connection for the two serial RS-485 communication ports is on the Power
Supply Module terminal strips. Port 2 is for RS-485 serial communication to Altronic
instruments, and port 3 is for RS-485 serial communication to a PC (personal computer) or
a PLC (programmable logic monitor) to perform remote monitoring or control functions if
desired.
3.5 Terminals marked IGN IN and PU IN are used by the DE-2200 system to detect either engine
rotation or ignition system firings. This input monitors changing signals such as those seen
oneithertheignitionshutdownleadoramagneticpickupmonitoringanenginemountedgear.
- The IGN IN terminal connects to the positive (+) C.D. ignition shutdown lead.
- The PU IN terminal connects to one magnetic pickup input; the other pickup wire
connects to the minus (!) terminal on the Power Supply Module.
NOTE: An installation may use only one of the terminals IGN IN or PU IN.
4.0 TERMINAL MODULE
4.1 TheTerminalModuleismadetoberailmountedand isthepoint ofinterfacebetween thefield
sensor wiring and the DE-2200 monitor system. A removable dual terminal strip is used for
the connection of the system to the equipment mounted discrete sensors which may consist
of up to 16 normally open or normally closed switches as well as up to 14 analog transducers
and 7 thermocouples selectable as type “J” or “K”. The 16 discrete sensor inputs are similar
to previous Altronic DA, DD, and DE annunciator systems and are numbered in the typical
annunciator format as 10-17, 20-27. The 14 analog inputs are numbered 30-37 and 40-45;
30-36 accept industry standard transducer signals in the range of 0-5 VDC. Inputs 37 and
40-45 accept 0-5 VDC transducers or industry standard type “J” or “K” thermocouples.
Connections from the Terminal Module to the Display Module are made using the 693115-x
series Cable Assembly.
44.2 TheDE-2200isdesignedtooperatewithindustrystandard,voltageorcurrentamplifiedoutput
transducers in the range of 0 to 5 Vdc or 0 to 25 mA. Four series of transducers are available
from Altronic: pressure transducers 691201-x, 691204-x and temperature transducers
691202/203-300, 691212/213-450.
4.3 PRESSURE TRANSDUCERS - The pressure transducers, Altronic P/N 691201-x and P/N
691204-x, are packaged in a rugged sealed case with a 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 back of the Terminal
Module using cable assembly P/N 693008-x.
4.4 TEMPERATURETRANSDUCERS- Thetemperaturetransducers, AltronicP/N691202-300,
691203-300 with a temperature measurement range of +5 to 300EF and the 691212-450,
691213-450 with a temperature range of -40 to +450EF are packaged in a sealed, stainless
steel housing with a 5/8"-18 UNF threaded body, and a Packard Electric “Metri-Pack”
connector. During configuration the standard calibration for the 691202/203-300 sensor is
selected as "dEG1" and the standard calibration for the 691212/213-450 is selected by
choosing "dEG2". The three wires from the transducer are: +5 volt excitation, temperature
output voltage, and minus return. These wires connect directly to the Terminal Module using
cable assembly P/N 693008-x.

4.5 THERMOCOUPLE INPUTS - The terminal module accepts industry standard type “J” or “K”
thermocouplesoninputs37and40-45. Automatic coldjunctioncompensationisbuilt-in. The
units can be configured to EF or EC. Both a high and low setpoint is associated with each
channel.ThemonitorcanreadtypeJthermocouplesbetween!76EFand1382EF(!60ECand
750EC) and type K thermocouples between !76EF and +1472EF (!60EC and 800EC).
5.0 MOUNTING
5.1 DISPLAY MODULE - Mount the Display Module inside a control panel or to a suitable flat
surfaceso that thedisplay is ata convenient viewingheight. Adrilling template andmounting
dimensions are provided. NOTE: Avoid mounting the unit with the LCD display facing direct
sunlight. The display operating temperature range is !31EF to +176EF (!35EC to +80EC).
5.2 POWER SUPPLY MODULE - Mount the Power Supply Module in the panel either on the
bottom or the side of the main panel. The Power Supply Module is made to be rail mounted
onto commercially available 32 or 35 mm DIN mounting rails. It is also made to plug directly
into the Terminal Module using the DB-25 connectors and is held together with screws and
screw locks. Two end brackets P/N 610751 should be used to keep the modules from sliding
off the ends of the mounting rail.
As an alternative, the Power Supply Module and the Terminal Module can be mounted
separate from each other on theDIN mounting rails but in the same panel; in this case, a DB-
25 male/female cable such as P/N 693115-1 is used to electrically connect these modules.
The operating temperature range of the Power Supply Module is !31EF to +176EF (!35EC to
+80EC).
5.3 TERMINAL MODULE - Mount the Terminal Module in the panel either on the bottom or the
side of the main panel. The Terminal Module and Power Supply Module are made to be rail
mounted onto commercially available 32 or 35 mm DIN mounting rails. The Terminal Module
ismade toplug directlyinto thePower SupplyModuleusing theDB-25 D-Subconnectors and
held together with screws and screw locks. Two end brackets P/N 610751 should be used
tosecurethemodulesfromsliding offtheendsofthemountingrail. TheTerminalModuleand
the Display Module are electrically connected with a DB-25 male/female cable, 693115-x
series or equivalent. The operating temperature range of the Terminal Module is !31EF to
+176EF (!35EC to +80EC).
5.4 PRESSURE TRANSDUCER - Mount the pressure transducer in the panel or in a manifold or
tube off of the engine. Do not expose the pressure transducer to temperatures above 221EF.
(105EC).
IMPORTANT: Pressure transducers will withstand overloads as high as 1.5 times rated
pressure. If the overload rating is exceeded, failure may occur. Pressure fluctuations occur
in most reciprocating systems; pick the transducer with a rating high enough to prevent
overload by peak pressures of pulsations. It is recommended that a pressure snubber be
usedwhich willreduce thepeak pressureapplied tothe transducer. Thelife ofthetransducer
will be extended with the use of a snubber or pulsation dampener.
5.5 TEMPERATURE TRANSDUCER - Mount the temperature transducer in a thermowell on the
engine or machine. The actual sensor is located at the bottom of the transducer body; to
ensure accuracy, the tip of the probe should be surrounded by the measured media.
IMPORTANT: Do not exceed the absolute maximum rating of the transducers, 350EF
(176EC) for the 691202/203-300 or 450EF (232EC) for the 691212/213-450. Care should be
taken to protect the wiring and connectors from contact with hot surfaces.

6.0 WIRING (SEE WIRING DIAGRAMS)
6.1 SYSTEM COMPONENT WIRING - A DB-25 male/female cable, 693115-x series or
equivalent, is used to connect the Terminal Module to the Display Module and secured with
the cable lock screws. If mounted on the same mounting rail, plug the Terminal Module
directly into the Power Supply Module using the DB-25 D-Sub connectors at the ends of the
modulesandsecurethemtogetherwiththescrewsandscrewlockscaptivetotheconnectors.
If the Power Supply Module and the Terminal Module are mounted separate from each other
(must be mounted in the same panel) a DB-25 male/female cable such as P/N 693115-1 or
equivalent is used to connect these modules.
6.2 POWER WIRING - Connect the supply power wires to the 12-24 Vdc input power terminals
on the power supply, plus to terminal (+) and minus to terminal (!); power requirement is 12
to 24 Vdc (10 watts max.). The DC!terminal must be connected to panel ground which
should be the same as engine ground.
NOTE: This is the return path for normally open sensors and must be connected for proper
operation. DO NOT ground this device directly to the ignition system common coil ground.
6.3 SENSORWIRINGDISCRETEINPUTS-Thesensorleadsconnecttotheremovableterminal
strips on the Terminal Module. The terminal numbers correspond to the display numbers
which also have a user assigned 20 character label associated with it. The sensor inputs are
numbered similar to previous Altronic DA and DD annunciator systems: 10-17, 20-27. The
set ofterminals labeled Rand S arefor remoteReset andStop respectively,with PRE/POST-
LUBE disabled. With PRE/POST-LUBE enabled, Reset is wired to a lube switch. Sensor
inputs 10-27 can be user-configurable as class A, class B or class C logic. Any sensor point
can be wired for normally open or normally closed operation. Any unused sensor input must
contain a short jumper wire across the input.
- Normally Open (N/O) sensor switches are wired with one wire to the bottom terminal strip
oftherespectivesensornumberandtheothertoenginegroundwhichshouldbethesame
as power minus (!). A short jumper from the bottom terminal to the top terminal must be
connected for normally open sensors (see wiring diagrams).
- Normallyclosed(N/C) sensorswitchesare wiredwithone wiretothebottomterminalstrip
andthe otherto thetop terminalstrip ofthe respectivesensornumber. Note thatthe short
jumper wire must be removed.
- Remote stop and remote reset are wired the same as the sensor switches and can be
used with either normally open or normally closed contacts.
Use a wire size of between 16 AWG (max.) to 24 AWG (min.) to connect the sensor switches
to the terminal strip connector. Strip the insulation back 3/8"; twist the exposed wires tightly
together. Insert the exposed wire completely into the terminal strip and securely tighten the
clampingscrew. Wires runningto sensorswitches mustbe ingood conditionor replacedwith
new wires. When running wires, take care not to damage the insulation and take precautions
against later damage from vibration, abrasion, or liquids in conduits. An explosion-proof
conduit is not required. However; wires should be protected from damage by running them
in a protective conduit or in sheaths where appropriate. In addition, it is essential that the
following practices be adhered to:

-6-
6.3 (continued)
A. Neverrunsensor wiresin thesameconduitwithignitionwiringor otherhighenergywiring
such as the AC line power.
B. Keep secondary wires to spark plugs and other high voltage wiring at least eight inches
(200mm) away from sensor and sensor wiring.
C. Sensor switches may be connected to any passive device using contacts such as
standardswitchgauges,pressureorlevelswitches. DONOTconnectsensorleadstoany
voltage producing element.
D. In the case of a field conversion where sensors have previously been used with Murphy
tattletales,itisrecommendedthatthesensorsbecheckedfrequentlywhentheDEsystem
is first put into use. Sensor contacts may be burned or pitted from past exposure to
ignition system primary voltage. It is advisable to replace such sensors.
E. If it becomes necessary to check sensor switch to panel wiring with an ohmmeter or other
checker, first DISCONNECT the plug-in terminal strips from the Terminal Module.
Applying voltage to the DE-2200 system through the sensor leads may damage the
device. In addition, the area should be tested as non-hazardous before such testing
commences.
6.4 ANALOGSENSORWIRING-Foreachanalogmonitoredpointinputs30-37and 40-45select
a transducer - either an Altronic pressure or temperature transducer listed above or one that
outputs a signal in the range of 0 to 5 Vdc or 0 to 25 mA. Mount as described above. Use
cable assembly 693008-x or similar to wire transducer to the Terminal Module. All unused
inputs must be shorted with a short jumper wire. An internal 5 volt sensor supply (500 mA.
max.) is available to power the Altronic transducers; see wiring diagrams. If the 5 volt sensor
supply exits the panel it must be fused with a 0.5 ampere fuse. If 24 volt powered sensors are
used the 24 volt supply to them must be fused appropriately. Take care not to damage the
insulationwheninstallingandtakeprecautionsagainstlaterdamagefromvibration,abrasion,
or liquids in conduits. In addition, it is essential that the following practices be adhered to:
A. Neverrunsensor wiresin thesameconduitwithignitionwiringorotherhighenergy wiring
such as AC line power.
B. Keep secondary wires to spark plugs and other high voltage wiring at least eight inches
(200mm) away from sensor and sensor wiring.
6.5 THERMOCOUPLESANDTHERMOCOUPLEEXTENSIONWIRE-Groundedorungrounded
type J or K thermocouples may be used. Use thermocouple extension wire of the same type
as the thermocouple probe to connect the thermocouple to the temperature scanner. Use
stranded thermocouple wire having a good moisture-resistant insulation such as PVC; for
higherambienttemperatures,TeflonorB-fibreinsulatedthermocouplewireisrecommended.
To insure an accurate signal is transmitted to the instrument, avoid any added junctions,
splices and contact with other metals. All unused inputs must be shorted with a short jumper
wire. Take care not to damage the insulation when installing and take precautions against
laterdamagefrom vibration,abrasion,or liquidsinconduits. In addition,itis essentialthatthe

14.0 AUTO PRE-LUBE / POST-LUBE OPTION
14.1 If enabled, AUTO PRE-LUBE is initiated by either a local contact closure of the reset
terminals on the terminal board or by the receipt of the appropriate serial command string.
To enable pre-lube the AUTO PRE-LUBE / POST-LUBE option must be selected when
configuring the system from the PC. The pre-lube time can be set from 0 to 999 seconds.
Upon initiation of the external reset, OUTPUT #4 on the power supply module will be
activated and remain activated for the length of the pre-lube timer and up to the configured
pre-lube RPM setpoint. The display will show “STATUS PRE-LUBE” on the top line
indicating that OUTPUT #4 is active. Upon the time out of the pre-lube timer and the
configured pre-lube RPM setpoint OUTPUT #4 will normalize and the display will return to
“TIMERS ACTIVE” or if the timers active timer has timed out “RUNNING”. Pre-lube will be
aborted by the detection of any monitored fault or the activation of the STOP key. If the pre-
lube timer is set to zero the system will act as though auto pre-lube was not configured.
RPM must be at zero during the activation of the remote reset to activate the pre-lube timer.
14.2 If enabled, AUTO POST-LUBE is initiated by the detection of any monitored fault or the
activation of the STOP key.
Toenable the post-lube theAUTO PRE-LUBE /POST-LUBE option mustbeselected when
configuring the system from the PC. The post-lube time can be set from 0 to 999 seconds.
Upon the detection of any monitored fault or the activation of the STOP key, OUTPUT #4 on
the power supply module will be activated and remain activated for the length of the post-
lube timer. Upon the time out of the post-lube timer OUTPUT #4 will normalize. Pre-lube
can be aborted by activation of either the CANCEL TIMERS key or the RESET key. If the
