1.3 Housings

ControlWave housings (whether base or expansion) are gold irridite­plated aluminum designed either for wall, DIN rail, or panel-mounting. They contain the printed circuit board (PCB) backplane that provides connections for the PSSM, the CPU module, any ECOMs, and any I/O modules.
Base
Expansion

1.4 CPU Module

Three base housings are available:
3-slot base backplane supports one PSSM, one CPU, and one I/O
module.
4-slot base backplane supports one PSSM, one CPU, and two I/O
modules.
8-slot base housing supports one PSSM, one CPU, and up to six I/O
modules.
You can substitute one or two ECOMs for I/O modules in slots 3 and 4 (if present) of the base housing.
Three optional expansion housings enable you to add an additional two, four, or eight I/O modules to either a 4-slot base or 8-slot base housing. However, you cannot install ECOMs in an expansion housing.
Note: For complete technical details on housings, refer to the
ControlWave Micro technical specification (CWM).
The CPU (central processing unit) module houses the multi-layer PCB, which contains the ControlWave Micro CPU, I/O monitor/control, memory, and communication functions.
The CPU module includes:
Sharp LH7A400 System-on-Chip ARM microprocessor with 32-bit
ARM9TDMI Reduced Instruction Set Computer (RISC) core, operating at 1.8V with a system clock speed of 33 MHz or 150 MHz.

1-4 Introduction Revised Aug-2015
ControlWave Micro Distributed I/O System Instruction Manual
Note: Do not confuse the CPU module (which has communication
components) with the Expansion Communication module (ECOM), which does not have a CPU component or a battery backup but does have additional communication components.
Figure 1-2. CPU Module with Three Serial Ports and One Ethernet Port
CPU Backup Battery
CPU Memory
CPU modules have a coin cell socket that accepts a 3.0V, 220 mA-hr lithium battery. This battery provides backup power for the real-time clock and the system’s Static RAM (SRAM).
There are several different types of memory used on the CPU module:
Boot/Downloader FLASH
Boot/download code is contained in a single 512 Kbyte FLASH chip. Boot FLASH also holds the value of soft switches, audit/archive file configurations, and user account and port information.
FLASH Memory
The CPU module contains 16 MB of FLASH memory. The FLASH memory holds the system firmware. The FLASH does not support hardware write protection.
System Memory (SRAM)
The CPU module has 2 MB of static random access memory (SRAM). During power loss periods, SRAM enters data retention mode (powered by a lithium backup battery). Critical system information that must be
Revised Aug-2015 Introduction 1-5
ControlWave Micro Distributed I/O System Instruction Manual
retained during power outages or when the system has been disabled for maintenance is stored here. This includes the last states of all I/O points, the values of any variables marked RETAIN and the values of any variables assigned to the static memory area.
SDRAM
The CPU module contains 64MB of synchronous dynamic random access memory (SDRAM). SDRAM holds a copy of system firmware and the current values of any variables not marked RETAIN or stored in the static memory area. This allows the system to run faster than it will from the SRAM memory. SDRAM is not battery-backed.

1.5 Power Supply/ Sequencer Module (PSSM)

The Power Supply/Sequencer module (PSSM) takes power from an external bulk DC power supply and then provides power through the ControlWave Micro Distributed I/O housing/backplane to all installed modules.
The PSSM operates from +10.7 to +30 Vdc or from +21.7 to +30 Vdc. You configure the nominal input supply configuration (12V or 24V) using configuration jumper switches on the PSSM.
The PSSM includes:
a wide input range Vin to 3.3V DC to DC Converter 1200 msec good power detection circuitry Vin out-of-specifications detection circuitry Watchdog output connector Status LEDs Vin 12-bit serial analog to digital converter
Note: The two versions of the PSSM currently available for use with
the ControlWave Micro Distributed I/O System are identical to those used with the ControlWave Micro Process Automation Controller. One version has a watchdog connector (see Figure 1-
3) the other does not (see Figure 1-4).

Board Fuse
The PSSM is fused to protect the entire system using a 5x20mm slow blow fuse F1 rated at 3 Amps.

1.6 Expansion Communications Modules

An optional Expansion Communications module (see Figure 1-5) provides two additional serial communications ports and optionally a piggy-backed dial-up modem. Two basic versions of the module are available. Both serial communication ports support speeds of up to
115.2 KB. The top communication port (labeled C1) supports RS-232 operation while the second port (labeled C2) supports RS-485 operation. Additionally, you can order the RS-485 port with isolation to 500 Vdc.
Figure 1-5. Expansion Communications (ECOM) Module

1.7 I/O Modules

The ControlWave Micro Distribution I/O System supports a wide array of factory-configured I/O modules including analog I/O, digital I/O, high speed counter, and several others for either local or remote field device wiring termination.
1-8 Introduction Revised Aug-2015
ControlWave Micro Distributed I/O System Instruction Manual
Refer to Chapter 3 for information on specific I/O modules. Figure 1-6 shows a typical I/O module housing.
Configuration jumpers on I/O modules accommodate individual field I/O user configuration. Terminations are pluggable and accept a maximum wire size of #14 AWG. All I/O modules have surge protection that meets C37.90-1978 and IEC 801-5 specifications. Each I/O module connects to the backplane using a 36-pin male card-edge connector. All I/O modules are provided with two 10-point terminal block assemblies (for local termination) or two 14-pin mass Termination headers (for remote termination).
All digital (or discrete) I/O modules have individual point LED status indicators that you can enable either with a jumper on the module or through a software setting.

You can mount base or expansion housings to a panel or a wall. When mounting one of these units to a panel or wall, place it according to the following guidelines:
Ensure that the front of the ControlWave Micro Distributed I/O
System is visible and accessible for service (for example, so you can easily install or remove modules).
Use the mounting holes provided in the base and expansion
housings (see Figure 2-2 through Figure 2-7).
Remove the base housing and any applicable expansion housings from their cartons and install them at the assigned work site.
Note: If you are attaching an expansion housing to a 4-slot or 8-slot
base housing, remove the three bus terminators JP2, JP3, and
JP4 (see Figure 2-8) from the backplane on the 4-slot or 8-slot
base housings. You also may need to remove the paper label
over the connector on the right back edge of the base housing.

ControlWave Micro Distributed I/O System Instruction Manual

2.2.3 Grounding the Housing

Caution
Do not install any modules in the base or expansion housings until you have mounted and grounded those housings at the designated installation site.
Base housings have a ground lug (see Figure 2-2 through Figure 2-7)
that accommodates up to a #4 AWG wire size. Once you have installed the base and any expansion housings, you must run a ground wire between the base housing ground lug and a known good earth ground.
Note: After you install the PSSM in the base housing, as an added
precaution we recommend that you run a #14 AWG wire from the TB1-3 power connection (Ground) to the same known good
earth ground.
Additional grounding guidelines include:
Use stranded copper wire (#4 AWG) for the base housing to earth
ground, and keep the length as short as possible.
Clamp or braze the ground wire to the ground bed conductor
(typically a stranded copper AWG 0000 cable installed vertically or horizontally).
Tin the wire ends with solder (using a high-wattage soldering iron)
prior to inserting the wire into the base housing ground lug.
Run the ground wire so that any routing bend in the cable has a
minimum radius of 12-inches below ground and 8-inches above ground.

2.3 Power Supply/Sequencer Module (PSSM)

Before we actually configure the PSSM and install it in the housing, we’re going to discuss some general information about how it works.

2.3.1 General Information about the PSSM

The Power Supply/Sequencer module (PSSM) plugs into slot #1 (first slot from the left) on the ControlWave Micro Distributed I/O System’s backplane using connector P1, a 44-pin female non-keyed header (see
Figure 2-2, Figure 2-3 and Figure 2-4).
Currently, we offer the PSSM in two configurations:
PSSM with Display Interface and Watchdog output (model 396657-
01-0, Revision A and above) (see Figure 2-9)
PSSM with Mode Switch SW1 & Display Interface (model 396657-
02-8 without Watchdog output, Revision A and above) (see Figure
2-10)
Figure 2-9. PSSM with Run/Remote/Local Switch, Display Interface, and Watchdog Connector
Revised Aug-2015 Installation 2-11
ControlWave Micro Distributed I/O System Instruction Manual
Figure 2-10. PSSM Module with Mode Switch, Display Interface, and without Watchdog Connector
Two terminal blocks (see Figure 2-9) provide external input power and
watchdog connector switch connections. Two red LEDs on the PSSM’s front panel enable you to monitor the status of the watchdog (WD) and Idle (IDLE) circuits.
Note: The Idle LED is usually on, indicating when the CPU has free
time at the end of its execution cycle. If the LED is off, it
indicates the CPU has no free time and may be overloading.
Six additional LEDs provide system status codes (see Chapter 5).
PSSMs contain a DC-to-DC converter that generates a +3.3 Vdc supply for the entire unit (that is, the CPU and various I/O modules that plug into the backplane).
2-12 Installation Revised Aug-2015
ControlWave Micro Distributed I/O System Instruction Manual
Power
Supply
An auxiliary +5 Vdc regulator powers low power detection circuitry and sequencer timing circuitry.
The power supply operates from +10.7 to +30 Vdc or from +21.7 to +30 Vdc. You can configure the nominal input supply configuration (12V or 24V) using configuration jumper switches on the PSSM PCB. See
Figure 2-9 and Figure 2-10.
Watchdog
Switch
PSSMs optionally include a watchdog metal oxide semiconductor field­effect transistor (MOSFET) switch connector. The purpose of the watchdog connector is to trigger an external alarm or annunciator if the ControlWave Distributed I/O System enters a “watchdog” condition in which the CPU cannot control the I/O. This occurs on power-up before the ControlWave project starts, if the unit is reset, or if the system loses
power. See Section 2.3.6.

2.3.2 PSSM Installation Overview

There are several steps you need to follow when you install the PSSM.
1. Identify the carton holding the PSSM and remove it from that carton.
See Section 2.2.1.
2. Set jumpers on the PSSM based on whether your external DC bulk
power supply provides +12V or +24V. See Section 2.3.3.
3. Slide the PSSM into slot #1 of the housing.
4. Unplug terminal block connector TB1 from the PSSM and wire it to
an external bulk DC power supply. See Section 2.3.5.
5. If you want to use the watchdog connector TB2, unplug it from the
PSSM and wire it to an external annunciator or similar device
according to instructions in Section 2.3.6.
6. After you configure and install the CPU module in slot #2 re-connect
terminal blocks to their connectors to apply power to the unit.

2.3.3 Setting Jumpers on the PSSM

The PSSM has three jumpers which you set based on whether your
bulk DC power supply will provide +12V or +24V. See Figure 2-9 or Figure 2-10 to locate the jumpers on your version of the PSSM.

2.3.4 General Wiring Guidelines

ControlWave Micro Distributed I/O System PSSMs use
compression-type terminals that accommodate up to #14 AWG wire. When making a connection, insert the bare end of the wire (approx
¼” max) into the clamp adjacent to the screw and secure the wire. To prevent shorts, ensure that no bare wire is exposed. If using
standard wire, tin the bare end with solder to prevent flattening and improve conductivity.
Allow some slack in the wire while making terminal connections.
Slack makes the wires more manageable and helps minimize mechanical strain on the terminal blocks.
2-14 Installation Revised Aug-2015
ControlWave Micro Distributed I/O System Instruction Manual

2.3.5 Wiring a Bulk DC Power Supply to the PSSM

Caution
At this time you can also connect power and watchdog wiring. However; for safety reasons and to prevent accidental damage to the your bulk DC power supply, do not connect the pluggable terminal block connectors TB1 and TB2 to the PSSM until after you install, wire, and configure the CPU module.
Follow the instructions in Section 2.3.4 General Wiring Guidelines when wiring connections.
You can connect one bulk DC power supply (nominally either +12 Vdc or +24 Vdc) to the PSSM. The PSSM then converts, regulates, and filters the power to +3.3 Vdc. For safety, the PSSM circuit has a 3A fuse.
The ControlWave Micro Distributed I/O System PSSM’s operating range is +10.7 to +30.0 Vdc (with nominal +12Vdc input source) or +21.7 to +30.0 Vdc (with a nominal +24Vdc input source).
Use the following formula to determine the maximum current required for the +12 Vdc or +24 Vdc bulk power used with a particular ControlWave Micro Distributed I/O System:
Bulk + 12/24 Vdc Supply Current = CPU* + Sum of all ECOM modules and I/O modules.
Refer to Table 2-1 for ControlWave Micro Distributed I/O System bulk
power requirements.

Terminal Block Connector TB1
Unplug removable connector TB1 from the PSSM and wire DC power
to the connector. We recommend you do not plug the connector back
into the PSSM until the CPU module is already installed in the housing.
TB1 provides three input connections for bulk power:
TB1-1: (+VIN) (+10.7V to +30V dc for +12V supply) (+21.7V to
+30V dc for +24V supply)
TB1-2 = (-VIN) (Supply Ground - PSGND) TB1-3 = Chassis Ground - CHASSIS ( )
Figure 2-11 shows the typical wiring at the PSSM’s TB1 block.
Figure 2-11. PSSM TB1 Wiring
Note
: As an added precaution, we recommend that you run a #14
AWG wire from the TB1-3 power connection (Ground) to the
same known good earth ground used for the base housing.
2.3.6 Wiring an External Alarm or Annunciator to the Watchdog Connector (OPTIONAL)
Caution
At this time you can also connect power and watchdog wiring. However; for safety reasons and to prevent accidental damage to the your bulk DC power supply, do not connect the pluggable terminal block connectors TB1 and TB2 to the PSSM until after you install, wire, and configure the CPU module.
Follow the instructions in Section 2.3.4 General Wiring Guidelines when wiring connections.
The version of the PSSM shown in Figure 2-9 includes an optional
watchdog connector. The purpose of the watchdog connector is to trigger an external alarm or annunciator if the ControlWave Micro Distributed I/O System enters a “watchdog” condition in which the CPU cannot control your I/O.
2-16 Installation Revised Aug-2015
Terminal Block
Connector TB2
ControlWave Micro Distributed I/O System Instruction Manual
A watchdog condition occurs when:
A watchdog timer expires. This occurs due to a reset of power
failure.
The CPU module detects that the regulated 3.3 Vdc or 1.8 Vdc
supplies are out of specification.
A MOSFET switch activates the watchdog connector whenever a watchdog condition occurs.
You must power the watchdog connector (TB2) from an external power supply. Unplug removable connector TB2 from the PSSM and wire
power to the connector. We recommend you do not plug the connector
back into the PSSM until the CPU module is already installed in the housing.
TB2 provides two watchdog MOSFET switch connections:
TB2-1 = VI - Watchdog MOSFET Switch Input TB2-2 = VO - Watchdog MOSFET Switch Output
The VI input on TB2 powers the watchdog switch; its switched output connects to the VO output on the same terminal block. You must reference the external power source connected to the VI terminal to the return point of the input source powering the PSSM (which is either –
VIN or PSGND on TB2). See Figure 2-12.

2.4 CPU Module

The CPU module, which controls the ControlWave Micro Distributed I/O System and handles memory and communication functions, can only be installed in Slot #2 of the backplane.
Note: Do not confuse the CPU module (which has communication
components) with the Expansion Communication module
(ECOM), which does not have a CPU component or a battery backup but does have additional communication components.
Identify the carton holding the CPU module and remove it from that carton. The CPU module has two RS-232 serial ports, one RS-485
serial port, and one Ethernet port (see Figure 2-13).

2.4.1 Setting Jumpers on the CPU Module

Each CPU module contains a number of jumpers (labeled with JPn) when n in the jumper number. See Figure 2-13 to locate the jumpers.
Note: When present, jumpers 1, 2, 3, 5, 6, and 9 (JP1, JP2, JP3, JP5,
JP6, and JP9) are reserved for factory use only. Do not alter these jumpers from their factory settings.
Jumper 4 (JP4) enables the Idle and Status LEDs on the PSSM. It
comes enabled from the factory. (We recommend you leave these LEDs enabled during initial installation and setup. If power conservation is an issue, you can disable these LEDs by removing the jumper.)
Jumper 7 (JP7) enables the Communication Port Status LEDs on the
CPU module. It comes enabled from the factory. We recommend you leave these LEDs enabled during initial installation and setup. If power conservation is an issue, you can disable these LEDs by removing the jumper.
Note: For maximum shelf life, the CPU module ships from the
factory with the installed lithium backup battery disabled. You must enable it when you install the CPU module by placing JP8 on pins 1-2.
Jumper 8 (JP8) enables/disables the lithium backup battery on the
CPU module.
Pins 1-2: Enables the CPU module’s backup battery.
Pins 2-3: Disables the CPU module’s backup battery (Factory
default)
Jumper 10 (JP10) specifies how COM1 is enabled.
Pins 1-2: Enables COM1 whenever DCD is active. (Factory
default)
Pins 2-3: Enables COM1 whenever you connect a cable to the
port.
Jumper 11 (JP11) when present, specifies how COM2 is enabled.
Pins 1-2: Enables COM2 whenever DTR is ON. (Factory

2.4.3 Connections to RS-232 Serial Port(s) on CPU or ECOM
Modules
An RS-232 port provides point-to-point, half-duplex and full-duplex communications (for a maximum of 20 feet using data quality cable).
Your CPU module includes either one or two RS-232 ports.
If you require additional RS-232 ports, you can purchase an optional expansion communication module that can include either one (ECOM Type 1) or two (ECOM Type 2) RS-232 ports. The ControlWave Micro Distributed I/O System can support up to two expansion communication modules, for a total of up to four additional RS-232 ports beyond those on the CPU module. Expansion communication modules reside in slot #3 and slot #4.

For the ControlWave Micro Distributed I/O System, half-duplex communications use Modbus or BSAP protocol, while full-duplex communications use point-to-point protocol (PPP). RS-232 ports use a
“null modem” cable (see Figure 2-15) to connect with other devices
(such as a PC, a printer, another ControlWave [except the CW_10/30/35]) when the ControlWave Micro DIOS uses the full­duplex PPP protocol.

Guidelines
Observe the following guidelines when constructing RS-232 communication cables:
Ensure that DCD is high to transmit (except when dialing a modem) Verify that each RS-232 transceiver has one active receiver while
disabled (in power down mode); connect the DCD signal to the active receiver.
Set CTS to high to transmit. If the port is set for full-duplex operation, RTS is always ON. Ensure that DTR is always high when port is active; DTR enables
RS-232 transceivers.
Note: Control DTR using the PORTCONTROL function block and
the _Pn_AUTO_DTR system variable in your ControlWave
project. If you turn DTR off through these mechanisms, the
port remains off, even though hardware is fully configured.
When port is set for half-duplex operation, CTS must go low after
RTS goes low.

Since the RS-485 port is intended for network communications, refer to
Table 2-12 for the appropriate connections for wiring the master, first slave, and nth slave.
Essentially, the master and the first slave transmit and receive data on
opposite lines; all slaves (from the first to the nth) are paralleled (daisy-
chained) across the same lines. Wire the master node to one end of the RS-485 cable run using a 24-gauge paired conductor cable (such as a Belden 9843).
Note: ControlWave Micro DIOS supports only half-duplex RS-485
networks.

To ensure that the “Receive Data” lines are in a proper state during inactive transmission periods, you must maintain certain bias voltage levels at the master and most distant slave units (end nodes). These end nodes also require the insertion of 100Ω terminating resistors to properly balance the network.
You must also configure switches at each node to establish proper network performance. Accomplish this by configuring switches listed so that the 100Ω termination resistors and biasing networks are installed at the end nodes and are removed at all other nodes on the network. You enable receiver biasing and termination (as well as 2-wire or 4-wire selection) using an 8-position DIP switch located on the CPU and
ECOM modules. See Table 2-4 in Section 2.4.2 Setting DIP Switches on the CPU Modules for information on RS-485 termination and loopback
control switch settings.
2.4.5 Connections to Ethernet Port(s) on the CPU Module
Caution
The RJ45 Ethernet ports are located on the CPU module. The PSSM also has one RJ45 port for the optional Display/Keypad. Never connect Ethernet to the Display/Keypad port or damage to the PSSM will result.
ControlWave Micro Distibuted I/O Systems support one Ethernet port. It uses a 10/100Base-T RJ-45 modular connector that provides a shielded twisted pair interface to an Ethernet hub. Two LEDs provide transmit and receive status indications:
Port assignments are:
Ethernet Port 1: CPU Bd. J6, 8-Pin RJ-45 - Shielded Twisted Pair A
typical Ethernet hub provides eight 10/100Base-T RJ-45 ports (with port 8 having the capability to link either to another hub or to an Ethernet communications port). Both ends of the Ethernet twisted pair cable are equipped with modular RJ-45 connectors.

When connecting a ControlWave Micro Distributed I/O System to an
external modem, use the cable configuration in Figure 2-23.
Figure 2-23. Full-duplex and Half-duplex Cable
Figure 2-24. ECOM Modem Installation

2.5.3 Modem Port (Type 1 ECOM only)

You can mount an optional 56Kb PSTN Hayes-type modem on a Type
1 ECOM (see Figure 2-24).
The ControlWave Micro Distributed I/O System then assigns the modem COM7 (if in slot #3) or COM11 (if in slot #4).
You can configure the MultiTech model MT9234SMI modem module for publicly switched telephone network (PSTN) operation. You can

ControlWave Micro Distributed I/O System Instruction Manual
also clock DTE/DCE serial data into (transmit) or out of (receive) the modem at rates up to 115.2 kHz.
The factory supplies the modem pre-installed or in kit form with all required hardware. You install it on the ECOM1 module and then use the Ports page in the Flash Configuration utility (in NetView, LocalView, or TechView) to assign ports. Configure a profile for the modem using AT commands submitted using a terminal emulation program (such as HyperTerminal). Users typically use AT commands only when checking the modem’s active or stored profile or when reconfiguring a modem (to turn auto answer on or off, etc.).
Prior to shipment from the factory, the MultiTech modems are pre­configured using the following steps:
1. Connect pin Enable modem setup by setting jumper JP2 on the
ECOM to 2-3.
2. Connect via HyperTerminal (Parameters = 9600, 8, N, 1, None)
to ECOM port C1 using the null modem cable (see Figure 2-15).
3. Send Factory Default = AT&F0

6. Write to Memory. = AT&W
7. Disable setup mode. Park JP2 (no connection)
Note: You can reconfigure the modem using AT commands and a
terminal program (like HyperTerminal). Connect pins 2 and 3 of JP2 with a suitcase jumper, and use a null modem cable (see
Figure 2-15) to connect the PC to the modem (COM4 or COM8).
Figure 2-25 shows a publicly switched telephone network (PSTN)
using a single master and three remote ControlWave Micro Distributed
I/O Systems (each equipped with a PSTN modem). This application
requires only one remote connection.
Use a cable with standard telephone connectors (RJ11s) on each end. Plug one end of the cable into the RJ11 connector jack on the ECOM and the end into a RJ11 wall jack. The telephone company provides the necessary subscriber loops at its central system along with the phone numbers for each destination.
Caution
Revised Aug-2015 Installation 2-33
Connect only one modem on each drop. If you attempt to parallel two or more modems across a single drop, an impedance mismatch occurs, adversely affecting the signal. Modems cannot provide reliable communications under these conditions.

The 56K PSTN modem is FCC-approved for use with public telephone lines. However, before you place a modem in operation, check the following items to make sure you meet all FCC requirements:
Connections to party line service are subject to state tariffs. Connections to telephone company-provided coin service (central
office implemented systems) are prohibited.
The equipment compliance information is summarized as follows:
o Complies with Part 68 FCC Rules.
2-34 Installation Revised Aug-2015
ControlWave Micro Distributed I/O System Instruction Manual
o Contains device with FCC Registration Number: AU7-USA-
25814-M5-E
o Ringer Equivalence Number (REN): 0.3B
Note: The sum of all the RENs on your telephone lines should
be less than five in order to assure proper service from the telephone company. In some cases, a sum of five may
not be usable on a given line.
Make any direct connections to PSTN lines through standard plugs
and jacks as specified in the FCC rules. The PSTN line connector plugs into J1 on the modem. Notify your telephone company that the
jack (connector) required for your device is one of the following:
o USOC: RJ11C or o USOC: RJ11W
Note: The jack provided on the Modem (J1) is a 6-pin TLECO RJ-
11. The connections to the modem are pin 3 PSTN-Tip, and
pin 4 PSTN-Ring.

2.6 Bezels

After the telephone company has installed the above jack, connect
the modem to your equipment by inserting the appropriate equipment interface RJ11 plug into the modem and wall connector.
Bezels are blue plastic covers (see Figure 2-27) that protect an adjacent
pair of I/O modules and provide an easy way for you to route wiring. The factory provides bezels with each order. Install bezels over I/O modules whenever the ControlWave Micro Distributed I/O System is operational; remove the bezels for maintenance procedures.
Bezels attach to the module covers of two adjacent I/O modules. Hooks
on the bezels (see Figure 2-27) attach to notches in the upper and lower
portions of the module covers. Align the hooks on the bezel with the notches on the I/O module covers and slide the bezel down. To remove the bezel, grasp its sides and gently squeeze them, and pull up and then away from the I/O modules.

Installation
Installing any I/O module in the ControlWave Micro distributed I/O system involves the same basic steps:
1. Remove the I/O module and associated I/O module cover from the
shipping carton.
Note: Modules normally ship from the factory completely
assembled.
2. Align the I/O module with its intended slot on the base or expansion
housing and slide the module into the housing. Make sure the module snaps into the appropriate securing notches on the housing.
3. Wire and plug the local or remote cable assemblies into the
appropriate module connectors.
4. After installing and wiring two I/O modules into adjacent slots in
the housing, cover the modules with a protective bezel. The bezels snap on and off for maintenance.
5. Using a PC running the ControlWave Designer and OpenBSI
software, configure the ControlWave project that runs in the ControlWave Micro host controller to accept the new I/O modules in the distributed I/O system rack and download the revised ControlWave project into the host controller.
Revised Aug-2015 I/O Modules 3-1
ControlWave Micro Distributed I/O System Instruction Manual
Note: This step is beyond the scope of this manual. Refer to the
ControlWave Designer Programmer’s Handbook (D5125) for further instructions.
Caution
Power down the ControlWave Micro distributed I/O system before you install or remove any I/O module. Shut down any processes the distributed I/O system may be managing (or switch them over manually or handle with another controller). Perform any hardware configuration (wiring, jumper configuration, and installation) only when the ControlWave Micro distributed I/O system is powered down.
Before any I/O modules can become operational, you must use ControlWave Designer to configure and then download the application (project) into the ControlWave Micro host controller.
Do not install any modules in the housing until you have mounted and grounded the housing at the designated installation site.
To ensure safe use of this product, please review and follow the instructions in the following supplemental documentation:

3.1 Module Placement

You place I/O modules in the I/O slots of the housing:

through 8.
Note: Some modules have placement restrictions. Note these in the
individual descriptions.
With a few exceptions (noted in the module descriptions), I/O modules support either “local termination” (field wiring connected directly to the module’s removable terminal blocks) or “remote termination” (field wiring connected to the remote headers under the module’s cover and routed to a DIN-rail mounted terminal assembly and then to field devices).
ControlWave Micro I/O modules use compression-type terminals that accommodate up to #14 AWG wire. Insert the wire’s bared end (approx. ¼” max) into the clamp beneath the screw and secure the wire. To prevent shorts, ensure that no bare wire is exposed. If using standard wire, tin the bare end with solder to prevent flattening and improve conductivity. Allow some slack in the wires when making terminal

connections. Slack makes the wires more manageable and helps minimize mechanical strain on the terminal blocks.

3.2.1 Local Termination

For I/O modules equipped with local terminal blocks, install the field wiring between the I/O module’s removable terminal block connectors and field devices (see Figure 3-1). (consult with the field device manufacturer for recommendations). Leave some slack and plan for wire routing, identification, and maintenance. Route the bundled wires out through the bottom of the I/O module assembly between the terminal block and the terminal housing.
Use AWG 14 or smaller wire
Figure 3-1. Module Wiring: Local Termination

3.2.2 Remote Termination

For I/O modules that support remote terminations, install cables between the module’s remote headers and the remote DIN-rail mounted terminal block assemblies (see Figure 3-2). Install field wiring between the DIN-rail mounted terminal bock assembly and field devices (see the wiring diagrams associated with each I/O module description).
Use AWG 14 or smaller wire (consult with the field device manufacturer for recommendations) for remote terminations. Leave some slack and plan for wire routing, identification, and maintenance. Route the cables running between the I/O module and the DIN-rail
