APPLICATIONS ASSISTANCE

This manualis designedto provide the necessary information for trouble-free installation andoperation
of your new Operator Interface Terminal (OIT). However, if you need assistance, please call Maple
Systems at 425-745-3229 or visit our web site at www.maple-systems.com.

INSTALLATION MANUAL 3

Read Me First!

Your new Maple Systems OIT comes from the factory configured with the default
communication settings: 9600 baud, no parity, 8 data bits, 1 stop bit, no

handshaking, no turn-around delay, 90° viewing angle, interactive mode, CR line

terminator, underline cursor, 1 space tab width, local echo enabled, local setup
enabled, local keyboard enabled, key click enabled, block echo enabled. You can
change these settings through the MAP450D’s local setup menus or by using the
STEPware-100 configuration software (sold separately). If you want to store
messages in the MAP450D, you must use STEPware-100.

To ensure that the OIT meets CE compliance, it is necessary to follow all
installation procedures described in this manual.

Introduction

Thank you for purchasing a Maple Systems MAP450D. You have selected a
rugged, reliable, and powerful operatorinterface for your application. This booklet
describes the steps necessary to ensure trouble-free OIT system operation. Please

read this booklet carefully!!

Static Awareness

It is best NOT to remove the rear cover on the OIT except when accessing the
terminal block pins or panel mounting the OIT. When the rear cover is removed,
the circuitry inside is exposed to possible damage by electrostatic discharge during
handling. Minimize the possibility of electrostatic discharge by:

CAUTION

• Discharging personal static by grounding yourself prior to handling the OIT.

• Handling the OIT at static-free, grounded work stations.

• Connecting the chassis of the OIT to a clean ground.

• Placing the OIT into an anti-static bag during transport.

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 MapleSystems 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 withthe carrier. Save the shipping containerand
packing material in case the equipment needs to be stored, returned to Maple
Systems, or transported for any reason.

1. Control Panel Design Guidelines

Pay careful attention to the placement of system components and associated cable
routing. These items can significantly enhance the performance and integrity of
your control application.

Figure 1 Control Panel Example

1.1. Control Panel Grounding

• The control panel should be connected to a good, high-integrity earth ground
both for safety considerations and shielding purposes. This must be a reliable
earth ground with a low-resistance path. The ideal earth ground would be a
copper grounding rod located close to the OIT and the control panel.

• 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 contact. For this reason, a separate wire braid should be installed from
the hinged control panel to the rest of the enclosure.

1.2. Power Supply Selection

• The power supply used to power the OIT should have an output between +12
and +30 VDC. The voltage should measure between +12 and +30V at the OIT
between Pins 2 and 3 of the OIT terminal block. A 24 VDC, 0.5 amp linear
power supply dedicated to the OIT is recommended.

• The power leads on the operating cable for the OIT should be 18AWG
2-conductor wire with a shield wire and protective shield foil. The shield of the
OIT operating cable must be connected to earth ground atboth ends of the cable.
Please refer to Section 2.

• 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 powerline filter should have a current ratingof at least
three amps with common mode and differential mode attenuation.

• The power supply that provides power to the OIT should not be used to power
switching relays orsolenoids unless noisefilter caps areconnected to each relay.

1.3. OIT Cable Routing

• Always route the OIT operating cable away from any AC voltage or host
controller wires.

• Never bundle the OIT cables together with 120 VAC power wires or with relay
wiring.

• Try to keep at least 8 inches (20 cm) of separation between the OIT cables and
other power wiring. If voltages greater than 120 VAC are used in the system,
greater separation is required.

• If theOIT cables mustcome near ACwiring, make sure theycross at 90degrees.

• Running AC power wires in a separate grounded conduit is the preferred method
for electrical noise reduction.

• Keep the lengths of the OIT cables as short as possible. Do not coil excess cable
and place it next to AC powered equipment.

1.4. Other Steps to Improve Noise Immunity

1010-0046A, REV 00

• Always install the OIT’s rear cover. This provides a shield against electrical
noise which can be generated in thecontrol panel by relays, motors, power lines,
and/or high frequency equipment. Ensure that all rear cover mounting screws
are properly secured.

• Any equipment used in the enclosure that operates at high frequency or high
current levels can be covered with a grounded metal shield.
