Introduction 1
Introduction - Welcome
Welcome to the Maple Systems’ BLU300 Series of Operator Interface Terminals (OITs). The BLU300 is a low cost,
easy-to-use graphical operator interface with membrane-style keypad. The BLU300 connects to programmable logic
controllers (PLCs) to provide the human-machine interface in industrial applications. The BLU300 Series has several
features not found in other low cost OITs. This manual explains the operation of the BLU300 Series OITs and how to
implement the many available features using the BlueLeaf Configuration Software.
BlueLeaf Support
OIT Models Supported
The BlueLeaf configuration software supports the BLU300 operator interface terminal which is a 128x64 pixel backlit LCD

Introduction 3
OIT Basics
Operator Interface Terminals (OITs) provide much more versatility than traditional mechanical control panels. An OIT
allows a plant floor operator to monitor current conditions of a control system and, if necessary, to initiate a change in the
operation of the system. OITs connect to programmable logic controllers (PLCs) typically through the PLC’s serial
communications port. The OIT can be programmed to monitor and/or change current values stored in the data memory of the
PLC.
OITs can have either text-based or graphics-based displays. A text-based OIT can display printable text characters but no
graphics. Some text-based OITs can display text characters in various sizes. A graphics-based OIT can display printable text
characters of varying fonts and sizes and graphics shapes such as icons, bitmaps, or pictures. Using pictures instead of words
or characters often greatly simplifies the operation of the OIT, making the OIT much more intuitive to use.
Some OITs use touch screen displays while others use a membrane-style keypad. Membrane-style keyboards are best used in
applications in which the keypad is likely to become dirty.
The Maple Systems BLU300 Series OITs are graphics-based membrane-style keypad OITs. Before we get any further into
the operation of these OITs, it is necessary to define some terms that will be used throughout this manual.
Projects
The OIT has two basic segments of internal memory. The code memory contains the information required by the OIT that
controls how it operates such as the features supported and how it communicates to a PLC. The OIT programmer does not
have the ability to change code memory. The project memory pertains to all of the screens created and any other features that
the OIT programmer can create using the BlueLeaf configuration software. Therefore, the term project is used to designate
the file that is sent to the OIT from the BlueLeaf software.
Objects
An object is any action that the OIT performs while it is communicating to the PLC. In order to get the operator interface
terminal to ‘do anything’, you must program the OIT with objects. Objects perform actions such as display text or graphics,
write a value to a PLC register, or display a message. Objects most often are graphics shapes that are to be displayed on the
OIT screen. For example, a Text Object is used to display text on the OIT. But objects are also used to configure the OIT to
perform some action. For example, a Jump To Screen Object tells the OIT to continuously monitor a PLC register that is
used by the PLC to request a new screen. Some objects can display a graphics shape on the OIT screen and
action. For example, a Function Key Object creates a graphic object on the OIT that indicates the current state of a PLC
register, when the tagged function key is pressed on the OIT.
Graphics Object
A graphics object is any text, icon, or picture that can be displayed on the OIT. Graphics objects are further defined by how
they are composed or created. A Text Object is a graphics object that displays text on the OIT screen. A Bitmap Object is a
graphics object that displays a bitmap on the OIT screen. Bitmaps are files stored in the OIT to display pictures. Bitmaps
use a pixel-based file format.
Screens
A screen is a window of information that can be displayed on the OIT. Screens can appear on the OIT display by a request
from the PLC or by a press from the OIT’s keypad. Each screen can display graphics objects and there is no limit to the
number of graphics objects that can be placed on each screen. The BLU300 Series is capable of storing up to 999 screens ,
but the actual limit is determined by the total amount of memory used for the application (maximum of 256Kbyte). A more
in-depth discussion of screens is covered in later chapters.

Installation of OITs 7
Chapter 1 - Installation of OITs
Before You Begin
Please read the following for proper handling of your new OIT.
Unpacking the Unit
Carefully unpack the OIT. Please read any instructions or cautions that appear on the shipping container. Check all material
in the container against the enclosed packing list. Maple Systems, Inc. will not accept responsibility for shortages against the
packing list unless notified within 30 days. The equipment and its accessories were inspected and tested by Maple Systems
before shipment; all of the equipment should be in good working order. Examine the equipment carefully; if any shipping
damage is evident, notify the carrier immediately. You are responsible for claim negotiations with the carrier. Save the
shipping container and packing material in case the equipment needs to be stored, returned to Maple Systems, or transported
for any reason.
Managing Electrostatic Discharge
It is best NOT to remove the rear enclosure of the OIT. When the rear part of the enclosure is removed, the circuitry inside is
exposed to possible damage by electrostatic discharge during handling. Minimize the possibility of electrostatic discharge
by:
• Discharging personal static by grounding yourself prior to handling the OIT
• Handling the OIT at a static-free grounded workstation
• Connecting the frame ground () connector of the OIT to a clean earth ground
• Placing the OIT in an anti-static bag during transport
CE Compliance
The Blue Series OITs have been tested to conform to European CE requirements per Council Directive 89/336/EEC. The
European Union created these requirements to ensure conformity among products traded in those countries. Specifically, the
Blue Series OITs meet or exceed the noise emissions and immunity requirements as set forth in the EN50081 (Emissions)
and EN50082 (Immunity) standards. These products are designed to withstand electrical noise in harsh industrial
environments. They also conform to requirements that limit electrical emissions. However, this does not guarantee that the
products will be totally immune from possible malfunction in cases where severe electrical noise occurs. Therefore, we
strongly recommend that you follow the guidelines outlined in this chapter for proper wire routing and grounding to insure
the proper operation of the Blue Series OIT.
NEMA Rating
The Blue Series OITs are rated for NEMA 4/12 or IP65 installations. This means that when the OIT is properly mounted to a
panel or other enclosure, the front enclosure of the OIT will provide protection to the inside of the panel from splashing
water, wind blown dust, rain, or hose-directed water. The OIT must be installed according to the instructions in this chapter
to be properly sealed.
Environmental Considerations
The Blue Series is designed to operate in temperatures from 0-50° C. It is intended primarily for indoor installations and may
not be suitable for certain outdoor applications. Avoid installing the Blue Series in environments with severe mechanical
vibration or shocks. Do not install the OIT in enclosures with rapid temperature variations or high humidity. Either may
cause condensation of water inside the device and eventual damage to the OIT.
1010-0300, Rev 02
8 Blue Series Installation & Operation Manual
Safety Precautions
Please observe the following precautions when installing the Blue Series OIT. Failure to comply with these restrictions
could result in loss of life, serious personal injury, or equipment damage.
Warning: Do not operate the OIT in areas subject to explosion due to flammable gases, vapors, or
dusts.
Warning: Do not connect the OIT to an AC power source. You will cause permanent damage to
the OIT.
Warning: Do not attempt to use a DC power supply that does not meet OIT power requirements.
You may cause malfunction or permanent damage to the OIT.
Warning: Do not power the OIT with a DC power supply used for inductive loads or for input
circuitry to the programmable logic controller. Severe voltage spikes caused by these devices may
damage the OIT.

Control Panel Example
Control Panel Grounding
The control panel should be connected to a good, high-integrity earth ground both for safety considerations and shielding
purposes. Maple Systems cannot overemphasize the importance of good grounding. If you fail to use good grounding
procedures during installation, sporadic malfunction of the OIT may occur:
• Connect the OIT’s chassis ground terminal to a reliable earth ground with a low-resistance path.
•
Route all earthground wires thatlead from the OIT, the PLC, the power supply, and the line filterto a central
earth ground point such as a barrier strip. This will ensurethat no ground current from onedevice influences
the operation of the other devices.
•
Connect the OIT chassis ground terminal to the control panel door using a heavy-gauge short braided cable
or ground wire to minimize resistance.
•
Connect the power cable’s shield wire to the OIT’s chassis ground terminal.
•
Connect the controlpanel to earth groundusing a copper grounding rod close tothe OIT and controlpanel.
Hinged doors on control panels do not provide a long-term electrical connection to the rest of the enclosure. Corrosion
develops over time and prevents good electrical contract. For this reason, a separate wire braid should be installed from the
hinged control panel to the rest of the enclosure.
For a more in-depth overview of ground wiring techniques, refer to technical note #1027, OIT Ground Wiring and Electrical
Noise Reduction, which you can find at www.maple-systems.com.
Connect OIT Chassis Ground to Control Panel
To reduce the possibility of electrical interference, connect the chassis ground terminal of the OIT to a clean earth ground. If
the control panel is metal, make sure it is properly grounded. Then connect a short heavy-gauge wire (#18 AWG) from the
chassis ground terminal of the OIT to a mounting bolt on the control panel door. The mounting bolt must have good
electrical contact to the control panel; scrape away any paint that may be covering the panel to provide a good connection.
1010-0300, Rev 02
10 Blue Series Installation & Operation Manual
If the control panel is made of a non-conductive material, it is essential that you connect the chassis ground terminal of the
OIT to a clean earth ground point located close to the panel.

Power Supply Selection
The power supply used to power the OIT should provide an output of +24 VDC 5% measured at the OIT power terminal
block. A 24VDC regulated power supply dedicated to the OIT is required (refer to Appendix A: Specifications for the input
current requirements).
The power cable for the OIT should be 18AWG, 2-conductor wire with a shield drain wire and protective shield (foil or
braid). The shield drain wire must be connected to earth ground at both ends of the cable. Please refer to the Connect the OIT
to Power section for more information.
A power line filter installed at the AC input to the OIT power supply is highly recommended as a safeguard against
conducted RF noise, which is often present on factory power lines. The wires connecting the output of the power line filter to
the power supply should be kept as short as possible to minimize any additional noise pickup. The case of the power line
filter should be connected to a quiet earth ground. The power line filter should have a current rating of at least 1 Amp with
common mode and differential mode attenuation.

Panel Preparation
A metal panel or mounting surface with a minimum thickness of 15 gauge (0.059 inch/3.3mm) if cold-rolled steel or
hardened steel, or 10 gauge (0.101 inch/2.6mm) if aluminum alloy (6061-T6 preferred) is required. Thinner panels or
surfaces may bow between the mounting clamps and not form a seal with the gasket.
The area of the panel or mounting surface where the gasket comes into contact must be flat and free of scratches, pits, and
other features that prevent the gasket from sealing properly. If the panel or mounting surface is not uniform, thick, flat, stiff,
or smooth enough, then a sealant such as silicone may be required.
* Clean and deburr the panel cutout before the OIT is installed.
WARNING
The OIT requires a stiff, flat, smooth mounting surface
free of blemishes to seal properly to NEMA 4.

Mount the OIT to the Panel
Installing the Screws on the OIT
4STEPS:
1. Prepare the four screw clamps for the BLU300 by inserting the clamps into the slots of the back
enclosure as show in the illustration above.
2. Snap the OIT into the panel cutout using the plastic brackets of the back enclosure. Make sure that all
metal clamps are properly in position.
3. Tighten the screw clamps until all are uniformly snug.
CAUTION: Do not over-tighten the screws beyond snugness, or you may damage the housing.
REINSTALLATION: Because the gasket will take a “set” to the panel, be sure to reinstall the OIT to the same panel cutout
when a NEMA 4 seal is required. For best results, also replace the gasket itself.
Configuration Wiring
The OIT must be configured for a particular protocol before use. The BlueLeaf software (used on a PC with Windows 95 or
higher) is used for configuring the OIT. For detailed instructions on installing and using the software, please refer to the
software documentation section of this manual.
Connect the OIT to the PC for Configuration
To configure the OIT using Maple System’s configuration software, you will need the OIT Configuration Cable, Maple P/N
7431-0102. Connect the end marked “HMI” into the RS-232 port on the OIT and connect the end marked PC into the proper

Factory Configuration
Each OIT arrives from the factory without a project file in the OIT. To use the OIT, you must first create a project , then
download the project to the BLU300. Please follow the directions enclosed in Chapter 2, Creating Your First Project,to
configure your OIT for the PLC that you are using.
Each OIT has local setup menus that allow you to adjust some of the settings of the BLU300. Use the local setup menu to:
• Set OIT comm port settings
• Adjust the contrast setting of the LCD display
• Set a time interval for the back light saver
• Set the internal clock
• Enable the internal buzzer
• Select language
• Assign a password to prevent unauthorized access of the local setup menus
• Assign the startup screen
The BLU300 comes with a CR2032 battery for the built-in clock. If the battery needs replacing, please follow the steps
below:
4To change the clock battery:
1. Use a small screwdriver to remove the battery cover on the back enclosure of the OIT.
2. Push the metal side lever to spring the battery loose.
