INSTALLATION MANUAL 5 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.
MAP450D • 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.
INSTALLATION MANUAL 7 2. Connecting the MAP450D to a Host Controller It is necessary to follow all installation procedures described in this chapter for electrical noise immunity and CE compliance. Host/Controller Operating Cable specific for the Host/Controller Tighten OIT Operating Cable Install the ferrite coil here OIT Power Supply Output Case GND Terminal Block Figure 3 MAP450D Cable Connections STEPS 1. Remove the four screws from the back of the OIT enclosure and open the two halves. 2.

INSTALLATION MANUAL 9 2.1. RS-232 (Interactive & Block modes) Interactive and Block modes support the 3-wire RS-232 configuration with TXD, RXD and signal common. The cable requires an overall shield to protect against electrical noise. Xon and Xoff can be used for communication handshaking. 3-Wire RS-232 Host Controller MAP450D Terminal Block TXD Pin 9 - RXD RXD Pin 10 - TXD Signal Ground Pin 8 - Return 2.2.
MAP450D 2.3. RS-422/485 (Network mode) Network mode supports the 3-wire and 5-wire RS-422/485 configurations. The 3-wire configuration has both transmit and receive on the same pair of wires plus a signal common. The 5-wire configuration has differential signal pairs for transmit and receive plus a signal common. In both configurations the signal pairs must be twisted and surrounded by an overall shield.
INSTALLATION MANUAL 11 See Detail A & B Less than 4000' Less than 12" Shielded Cable OIT #1 OIT #2 TERMINATOR HOST 2 Pair Twisted Shielded Cable 24 Gage Wire TERMINATOR There are several different forms of communications networks. Maple Systems’ OITs utilize the multidrop format. The host controller, located at one of the network ends, is connected to the OITs via a continuous com-link. Each OIT is connected to the network by locally tapping into the com-link with short stub cables.
MAP450D Network Termination The com-link cable must be properly terminated to reduce the amount of interference and noise pickup from the surrounding environment. This is accomplished by using a termination circuit at both ends of the network cable. The following figure shows a typical termination circuit. The host termination is only needed if the host controller’s RS-422/485 adapter does not contain any built-in terminator circuitry.
INSTALLATION MANUAL 13 The cable shield must not be used as the signal ground. It is tempting to try and reduce the cost of 5-wire cabling by using a 4-wire cable with the shield used as the signal ground. DON’T DO IT. The initial cost savings are always exceeded by the maintenance costs once the system is operating under field conditions. It is often necessary to completely replace the network com-link with the proper cable (5-wire plus shield) to eliminate noise problems in the system.
MAP450D 3. Mounting the MAP450D 3.1. Panel Mount The OIT is installed in a panel by separating the front and rear covers of the OIT, and then sandwiching the panel between the two. The gasketed surface of the OIT’s front cover provides the environmental seal to NEMA 4 and NEMA 12 standards. The rear cover helps shield the OIT from dust, dirt, induced electrical noise, and physical damage. The OIT is mounted using four #6-32UNC screws sandwiching the OIT halves to panel.
INSTALLATION MANUAL 15 IMPORTANT: When panel mounting the MAP450D, do not catch the display connector on the panel cutout. The display is exposed while panel mounting and extra care should be taken. The display can be damaged if the display cable connector, which protrudes from the panel cutout, is touching the panel when tightened. To avoid damage, place the MAP450D gently onto the panel while monitoring for this condition. 3.2.

The length of the mounting screws is equal to the plate thickness plus 1/4 inch. NOTE: The mounting screws must not be torqued to more than 18 pound-inches.
INSTALLATION MANUAL 17 4. Configuring the MAP450D The MAP450D has many operating parameters that control how it communicates to the host controller. These operating parameters can be changed in three ways: from the MAP450D’s keyboard when it is in Configuration mode, when the host controller sends a Configuration Control Command, or by downloading a STEPware-100 project. This chapter explains how to connect the MAP450D to a PC so you can download a project from the STEPware-100 configuration software. 4.

MAP450D Appendix B Differences Between MAP450D and MAP450B The MAP450D uses the same enclosure, display, keyboard and overlay as the MAP450B, but includes the following differences: 1. The MAP450D can be configured using the Windows-based STEPware-100 configuration software. 2. The MAP450D stores and displays up to 500 user-definable messages. 3. The MAP450D stores the configuration parameters and user-definable messages in flash memory. 4.
