Operator Safety Information
The safety information in this summary is for the benefit of operating personnel.
Warnings and Cautions will also be found throughout the manual where they apply.
PRODUCT USAGE WARNINGS:
For fire and electric shock protection, DO NOT connect the input channels to objects at
elevated electrical potential. The common terminal of each measurement input channel
is not isolated from the common terminal of the input power connector and the RS-232
serial data port while that channel is being measured.
This interconnected common circuitry is not connected to ground or to the
enclosure of the Logger. If the Logger is interconnected to a desktop computer,
its internal circuitry very likely could be connected to ground through the serial
data port of the computer. The Logger enclosure and the measurement circuitry
provide functional isolation of the measurement and data circuitry sufficient to
allow for small electrical noise-related potentials to occur. This functional
isolation is not intended for electrical safety isolation. Therefore for electricshock protection and to prevent fire and damage to data interconnect wiring due
to high currents, the input channels must not be connected to objects at elevated
electrical potential.
• Do not operate the Logger in flammable or explosive atmospheres. Such usage
constitutes a fire or explosion risk.
• For electric-shock protection, only operate the AC power adapter indoor
location.
• For continued fire and electric shock protection, use only the specified power
adapter.
• For continued fire protection, use only the specified optional DC power cable,
which incorporates a two-ampere fuse.
A two-ampere fuse is incorporated in the cigarette lighter plug which is part of
the DC power cable. This fuse provides overcurrent protection should a short or
overload circuit occur in the Logger or the DC power cable.
OM-5000 uvu
For protection of the Logger itself, observe the following:
• Do not immerse the Logger in liquids.
• Do not subject the Logger to sharp impacts or drops.
• Do not expose the Logger to corrosive environments.
• Extended exposure to temperatures below the specified minimum may
damage the battery (optional external rechargeable battery pack only).
• Extended exposure to temperatures above the specified maximum may
damage the Logger itself or its optional external rechargeable battery pack.
• Do not excessively stress the power input, the RS-232 serial data, and the
accessory port connections.
The warranty will not cover damage caused by neglect or abuse of this product.
To maintain the safety features incorporated in this product, operation must be in
strict compliance with the requirements specified herein.

1.0 GENERAL INFORMATION AND FEATURES
This section explains the Features for the OM-5100 (Bench Top) and OM-5200 (Wall
Mount) Systems.
1.1 INTRODUCTION & SYSTEM OPERATION
Omega's digital Logger can be furnished with a variety of multiplexers and other
circuitry for various logging tasks.
The Logger is completely self-contained and equipped with a built-in 24-column
thermal printer, an alphanumeric keyboard, a 16-digit vacuum-fluorescent display, a
real-time clock (with rechargeable 30-day battery backup), and an RS-232 serial data
port for connection to a computer serial port.
An AC Power Adapter provides 12 V DC for powering the Logger. North American and
selected international configurations of this power adapter are available.
The Logger includes a Data Cache memory that provides temporary storage of logged
data for reviewing before printing or uploading to a remote computer. RS-232 cable for
connecting to a computer, Accessory board with an external print trigger input; Relay
contact signal outputs for high and low alarms; and an optically isolated serial interface
for use with optional accessories such as the 20-relay alarm card. Also available are:
carrying case, and cables for operating from an automotive 12V DC source.
The Logger can be programmed directly from the keyboard or from a remote computer.
Programmable functions include:
1. Current date, time, and log interval.
2. The contents and format of the printout.
3. The configuration of each channel to match the kind of sensor to be used, such
as thermocouple type, voltage input, and pH probes.
4. The number of channels scanned and which channels are to be skipped. Also
the dwell time between channels and a hold command for continuous logging of
one selected channel.
5. Scaling the display reading to accommodate various input sensors by
multiplying, adding, or subtracting (mX+b).
6. High and low alarm points.
7. Engineering units.
8. Default unit of temperature (C or F).
9. Nonvolatile storage of the configuration for your system in an electrically
programmed ROM.
OM-5000 u1u
1.1.1 LOGGER MAINFRAME
The Logger Mainframe, as diagramed in Figure 1-1 consists of a microprocessor with
internal EEPROM and external RAM and ROM. The printer, display, and real-time clock
subsystems communicate with the CPU over a serial bus. The processor also receives
data from a 24-key keyboard and is capable of communication to external computers or
devices through the RS-232 port. The serial (SPI) bus is also used to communicate
control and input information to the MUX, Accessory, and Alarm cards.

1.1.2 MULTIPLEXER
Multiplexers perform the signal conditioning functions for the Logger. The multiplexer
shown in the block diagram below is designed for use with thermocouple and voltage
inputs. Relays select which input (voltage or thermocouple) is to be read. The input
signals are amplified and digitized by the A/D converter. Provision is also made for
measuring the temperature at the thermocouple attachment point and the system zerovoltage input. Using these parameters, thermocouple readings are compensated for
junction temperature, and offset zero drifts are canceled. The CPU controlled range
switch is set according to the type of input that is selected. Information as to the
channel type, display units, and alarm points is stored in EEPROM in the multiplexer,
allowing you to change multiplexers without losing channel configuration information.
The plug-in accessory board and optional Alarm Cards can be plugged into the
multiplexer.

Locate the Wall Mount template. Observe the indicated setbacks from obstructions
when placing the template. Mark four mounting hardware locations on the wall. Drill
holes for the hardware and insert the anchors into the drilled holes. Tighten the screws
into the anchors until only about 1/4 inch is exposed. Slide the key-hole-shaped
mounting holes in the bottom of the Logger over the screws. It is important that there be
space around the Logger for the printout paper.
The Knock-out tabs in the base may be used for conduit entry if more permanent
installation is desired.

OM-5000 u12u
2.7 GROUNDING THE ENCLOSURE
WINDOW
The rear panel incorporates a threaded chassis-connection point, identified with the "chassis
connection" symbol, which may be used for grounding the enclosure should the user desire to do so.
This terminal is not required to be used for "protective grounding" because the unit is only powered
by the low-voltage Power Adapter or optional rechargeable battery pack. Also, the measurement
circuits must not be connected to hazardous circuits. The enclosure is functionally isolated from the
internal circuits.
2.8 PAPER INSTALLATION
1. Unwind several inches of paper from the paper roll.
2. Fold the end of the thermal paper over creating a straight flat edge. This creates
a strong paper edge and allows the paper properly center in the printer when
inserting it into the rear paper slot on the printer. As shown in Figure 2-9 the
thermally sensitive side (printing side) of the paper is down.
FRONT
PAPER “FEED” KEY
Figure 2-9
3. Insert the paper into the rear printer slot as shown in Figure 2-9. Turn the Logger
“ON”, then press and hold the FEED key to feed the paper through the printer.
Paper orientation is important because only one side is coated for thermal
printing.
4. After the paper appears in the front window, pull several inches through.
5. Test the operation of the printer & paper-feed mechanism by turning the unit
“OFF” and back “ON”. When finished examine the printed messages for clarity.

2.9.1 DATA PORT CONNECTION
When the Logger is logging, data is saved in the internal cache RAM. The OM550/5000 Windows software supplied with the Logger is used to transfer this data
through the RS-232 Serial Port to a PC for analysis and storage. Prior to transferring
data, the Logger must be connected to a PC with the supplied RS-232 cable assembly.
The cable is fitted with a 9-pin connector for the Data Port on Logger and a 25-pin
connector for the PC COM port.
Figure 2-12
To minimize danger to personnel, and to avoid ground loops which could affect
measurement accuracy, never connect the Logger to a PC and to the signal
inputs simultaneously!

16 unit labels are listed in a table and may be assigned to any of the Logger channels.
For example, if unit label 04 is assigned to a channel, an "A" will be displayed and
printed following the data on the channel. Unit labels 14 and 15 are user
programmable, and up to a three-character label may be programmed into these table
positions (refer to section• CONFIGURATION UNITS ).
•• CONFIGURATION ALARM TABLE
In a manner similar to the system used for Units Tables shown in Figure 3-4 the Alarms are
assigned to channels by selection from a table of possible numbers. All alarm values except 00
(NONE) are user programmable, and may be either positive or negative. Alarm values are numbers
only and assume the format or decimal printing position of the channel to which they are assigned.
After alarm values are assigned to channels a complete list of channels and alarms can be printed
out by pressing the ALARM TABLE key.

3.2 PROGRAMMING
3.2.1 KEYPAD INTRODUCTION
When programming data into the Logger, be certain that a beep is heard when pressing a key to
insure that the CPU has responded to the keystroke. Most keys perform one primary, one alpha, and
one alternate function. Program data entry is done by displaying an example of how the data is to be
entered and flashing the position at which the data is to be entered. If data out of range for the
function being programmed is entered, the Logger will not accept the data.
In the following instructions and examples, MSD means most significant digit and
LSD means least significant digit.
