1.2 PHYSICAL OVERVIEW

The iS³ has a simple package. The following section briefly describes the front panel, the back panel and the connectors.

1.2.1 Front Panel

1.2.1.1 Communication Ports

The front panel of the iS³ shows 2 standard ports: an RS-232 (DB-9, DCE, female) craft port and an Ethernet 10BaseT (RJ45) port. As an option, either a second RS-232 port or an internal modem could be added. In the case of an RS-232 DEVICE DTE port, an additional DB-9 (DTE, female) would be added on top of the first. In the case of the modem, an RJ11 would be added, again just on top of the standard RS-232 CRAFT DCE port.

+24Vdc Model +24Vdc 18Vdc to 32Vdc Table 1 – Input voltage specifications

Note: The power supply is protected against a reverse polarity being connected to its input power pins. All other back connector pins, besides in J1, are ±60Vdc protected in the case of analog inputs.


17

Fuse Information

For power input, a fuse and an unattached in-line fuse holder is supplied with each iS³.

2.2.1.1 Fuse

Many signals besides power input on the iS³ need to be protected by external fuses, since they are connected to live battery voltages. Slow blow cartridge (tubular) or other fuse types should be used. The following cartridge (tubular) fuse part numbers are recommended. Equivalents can also be used:

Littelfuse: 313.500 (1/2A 250V)

Belfuse: 3SB500 (1/2A 250V)

2.2.2 Power supply fuse holder

The Multitel supplied power supply in-line fuse holder bears a clear ”HOT SIDE” indication on one of its wires. This sign prevents this internal contact from coming out of the in-line fuse holder insulating body whenever a fuse is changed (fuse holder opened). Removal of this sign could result in unprotected short-circuits to surrounding electrically connected metal which would melt wiring and possibly start a fire. The other wire does not provide such protection. Therefore, the “HOT SIDE” labeled wire should be connected to –48 or +24Vdc.

WARNING

Powering a 24Vdc iS³ on a 48Vdc supply may result in permanent damage or unit malfunction. If the iS³ is powered from –48Vdc, then fuse the “Battery-” signal. If the iS³ is powered from +24Vdc, then fuse the “Battery+” signal.

The iS³ cannot normally measure a -48V plant voltage when powered in +24V and vice-versa (without introducing an important measurement error). The iS³ voltage inputs are calibrated according to its operating voltage. In an application where both battery voltages co-exist it could be possible, on a special order, to calibrate specific voltage channels to be connected to -48Vdc and others on +24Vdc. These channels must then be connected to the voltage they were calibrated for, or else important measurement errors will occur.

2.2.3.2 Analog Channels

Battery (Vdc): 0 to 70 ± 0.2%

Midpoint (Vdc): -5 to +5 ± 0.2%

Humidity (Vdc): 0 to 4 ± 0.2%

Shunt (mVdc): -50 to +50 ± 0.2%

Temperature (�A): 0 to 400³ ± 0.6%

2.2.3.3 Binary Inputs

Level Detection GND level (V): ±0.00 to ± 2.00

FLOAT level (V): ±2.00 to ± 8.00

BAT level (V): from ± 8.00

WARNING:

The midpoint "+" signal connection must always be connected to BRG.

In a -48Vdc system, BRG is positive meaning the midpoint "+" signal shall be connected to the battery positive post.

In a +24Vdc system, BRG is negative meaning the midpoint "+" signal shall be connected to the battery negative post.

The midpoint "-" signal connection must always be connected to the battery.

In a -48Vdc system, the battery is negative meaning the midpoint "-" signal shall be connected to the battery negative post.

In a +24Vdc system, the battery is positive meaning the midpoint "-" signal shall be connected to the battery positive post.

Whatever the battery voltage and polarity, the midpoint signal lead must always be connected to the battery midpoint.

Therefore, when measuring midpoint voltages on +24Vdc systems, the midpoint "BATT_STR1+" signal shall be connected to BRG, the midpoint "BATT_STR1-" shall be connected to +24Vdc and the midpoint signal lead shall be connected to the battery midpoint. The same also applies to the other midpoint signals on the iS³: BATT_STR2 on the iS³ main board and BATTERY_STRING3, BATTERY_STRING4 and BATTERY_STRING5 on the DCPM-1 expansion board.

3 MOUNTING

The following chapter describes the iS³ installation options.

3.1 RACK MOUNTING

The iS³ can be rack-mounted using 19” or 23” brackets.

Figure 8 - iS³ on rack mount brackets

3.1.1 Rack-mount Bracket

The iS³ is provided with a rack-mount bracket, which must be preferably installed on the left side of the unit to avoid that the cables connected in the front panel do not obstruct the view of the LED indicators of the interface. The cables connected in the front panel of the iS³ must be clipped through the wire saddle and directed through the slot in the bracket all the way to the back of the rack for connection. Along with this bracket there are two (2) other important parts:

A universal washer plate

A wire saddle

The universal washer plate helps ensure a proper adjustment of the bracket to the rack frame. That is, rack frames can have either 1” or 1 ¼” spaced holes where to tighten the brackets; the universal washer plate allows the tightening of the bracket to either of the two (2) types of hole spacing in the rack frame.

The wire saddle allows for cable rest.


24

Figure 9 - Rack-mount bracket

3.2 WALL MOUNTING

Wall mounting and flat mounting are also possible. The figure below shows you how to use the wall-mounting brackets to properly and securely install the iS³ on a flat surface.

Figure 10 – Wall-mounting brackets


25

The iS³ can also be installed on a cabinet door, which implies systematic movement and a dose of overstrains to the cable connections. You should make sure, when you do the cable set up for this case in particular, that there is no movement or loose vibrations in the area surrounding the connector and that the cables are not too tight or strained from the fixation point on the door lid to the fixation point in the cabinet. That is, you should use adhesive squares for cable ties on the door lid as well as on the cabinet wall to ensure that the part of the cables that will be submitted to constant movement is loose enough to avoid damage. The parts of the cables that connect directly to the equipment must not have room for regular movement or shaking. For more details, consult the iS³ Harness Specifications.

3.2.1 Cable Strain Relief Insert

This insert incorporates a punched hole at one end and is used to help tightly and securely maintain cables. The insert can be used only with the crimp type connectors option in a rack-mounted installation.

Figure 11 – Strain relief insert


26

3.2.2 Bracket Inserts

A bracket insert is the piece of the brackets that slides into the aluminum case side rails of the iS³.

Figure 12 – Bracket insert


27

3.3 ESD PROTECTIVE COVER

The iS³ is equipped with a protective cover to help protect both the cable assembly from any damage and the equipment from electro static discharge (ESD) in wall-mount applications.

To facilitate the insertion of the iS³ ESD protective cover, there must be at least six (6) inches distance free from any obstacle at the back of the unit.

Figure 13 - ESD protective cover parts

1. Remove all white protective strips from the ESD protective cover.

2. Insert the extension brackets in the iS³ back side slides.

3. Firmly tighten the holding screws to make sure the brackets remains in place.

4. Make all necessary connections on the back of the iS³.

5. Screw the ESD protection cover on the brackets.


28

3.4 LED QUICK REFERENCE

The iS³ is provided with a quick reference card that will contain the necessary and additional information about the LED indications that you will configure for your iS³. It’s provided in the form of a label and a self-adhesive label holder that you can place either on the right side of the rack-mount bracket or on the top panel of the iS³ in wall-mount applications.

Figure 14 - LED Quick reference card

4 INSTALLING ELECTRICAL INTERFACES

This chapter will describe in detail how to connect the iS³ to external transducers and wire everything so that analog and binary inputs read properly. It will also show you how to properly ground the iS³ and power it.

See the document titled “iS³ Harness Specifications” for more information.

4.1 BACK CONNECTORS

The back connectors are used for powering the unit and I/O interfacing. Two (2) types of female connectors are available, crimp- or screw-type connectors.

The male connectors on the back of the iS³ are AMP type connectors, as specified in the figure below.

Figure 15 - AMP103166-6 (16-pin) and AMP103166-8 (20-pin) male connector (on PCB)

4.1.1 Crimp Type connector

The mating female connectors, to which wires will be attached, are as shown below.

The cable harness is delivered pre-assembled from the factory. Contact Multitel for a standard or custom wiring harness or for further information.

Figure 16 - AMP 102448-6 (16-pin) AMP 102448-8 (20-pin) mating female connector (without wires)

Figure 18 - Bottom cover (16-pin: P/N 102536-6; 20-pin: P/N 102536-8)

Figure 19 - Connector (female) complete assembly

Note: The manufacturer of these parts is AMP/Tyco Electronics. The suggested wire type for cabling iS³ back connectors using the AMP 102448 type connector is solid, gauge-22 wire.

4.1.2 Screw Type connector

The mating female connectors, to which wires will be attached, are as shown below.

These connectors can accommodate various types of wire gauges from #14 to #30 AWG. The use of screwdriver 1/8 (3mm) is recommended.


31

Figure 20 - Screw connector adaptor

Note: The manufacturer of the connector that is parts of the adaptor is Wieland.

4.1.3 Ground Lug

Proper grounding of the unit is very important. Use the ground lug, see Figure 21 and Figure 22 to properly ground the unit. Use gauge 14 stranded wire to connect the lug to the nearest frame ground. Having the iS³ properly frame-grounded is very important, namely for safety reasons, ESD/surge protection and electromagnetic emissions.

GROUND LUG

Figure 21 - Ground lug location, without expansion board


32

GROUND LUG

Figure 22 - Ground lug location, with expansion board

4.1.4 Power Connector

The power connection is located on J2, pin 9/10 (battery -) and 19/20 (battery +). The logic ground connection, on pins 8 and 18, should be wired to the common battery return ground (BRG) of the system. Note that many other inputs use this same connector.

Note: Reversing the polarity on the power input pins will not harm the iS³, but the unit will not be operational. It will remain “unpowered”.

4.1.5 Connector Pinouts

See COMPLETE I/O CONNECTOR PINOUT for a list of all back connectors and their pinouts.

4.1.5.1 Standard Connectors

Standard connectors on the back of the unit are labeled J1, J2, J3 and J4. J1 is a 16-pin connector. J2 to J4 are all 20-pin connectors.

4.1.5.2 Optional Connectors

Depending on the type of add-on I/O board installed, additional connector pinouts will vary. The connector type will stay the same. Optional connectors on the DCPM-1 option are 20-pin connectors and are labeled J5 and J6.

4.2 FRONT CONNECTORS

See the document titled “iS³ Harness Specifications” for more information.

4.2.1 Standard Communication Ports

4.2.1.1 RS-232 Interface – CRAFT Port

The on-board standard RS-232 port is used as a temporary or craft port. This is a female DB-9 connector. This port is DCE, meaning that you need a straight cable to connect it to a standard PC serial port. It supports baud rates up to 115.2Kbps.

4.2.2 Optional Communication Ports

4.2.2.1 RS-232 DEVICE DTE Port

The RS-232 DEVICE DTE port is used as a permanent port. This is a female DB-9 connector. This port is DTE meaning that when connecting to your PC, you need a “null-modem” type cable. On the other hand, hooking a modem directly to this port usually only requires a straight cable (but with male connectors at both ends). This port supports baud rates up to 115.2Kbps.

iS3 – INTELLIGENT SMALL SITE SUPERVISOR INSTALLATION PROCEDURE

43

5 INSTALLATION PROCEDURE

The following section will describe a step-by-step procedure to guide you through the installation of an iS³.

When working in the site, proper safety rules shall always be observed.

5.1 Step 1: Mounting

Locate the proper place to install the device. Depending on the type of mounting, use the rack or wall brackets. First install the brackets on the iS³. To do so, you may use a flat surface (table top) to help install the brackets for perfect horizontal alignment.

5.2 Step 2: Install in Rack or on Wall

This simple step consists in placing and securing the iS³ and its brackets in place by tightening all screws.

5.3 Step 3: Connect Frame Ground

Using a gauge-14 stranded wire (do not use a smaller gauge), install the frame ground of the iS³. Proper mounting is shown in Figure 34.

5.4 Step 4: Run Wires

It is usually preferable to install the transducers and connect the wires to the physical measuring point before connecting the connectors to the iS³.

5.5 Step 5: Connect to iS³

5.5.1 Crimp Connector

Use the wiring harness provided with the unit.

Properly identify the connectors (for example J1 to J4) and plug each of them in the proper connectors on the back-end of the iS³.


44

5.5.2 Screw Connector

1. Slide the side support brackets in the grooves at the back of the unit. Tighten the screws.

Note: The screws have been pre-installed at the factory. It is not necessary to tighten them too hard.

Attention There is a right-side and a left-side bracket. Make sure that the screw holes for the optional protective cover are up.

Figure 35 – Installing side support brackets

2. Properly identify the connectors (for example J1 to J4) and plug each of them in the proper connectors on the back-end of the iS³.

J1 has a 16-pin connector, while J2 to J4 have each a 20-pin connector. Each screw connector is identified with a number from 1 to 20. Numbering corresponds exactly to the iS³’s male connectors. The wiring schematics at the end of this manual may be used for reference.

Figure 36 – Connector identification and insertion


45

3. Slide the back support in place and tighten the screws. Connectors should not move at this point. The support must enter in the groove provided at the back of each connector in order to block them in place.

Figure 37 – Installing the back support

4. Make the necessary connections for this row. Avoid passing wire sleeves between these connectors. Doing so might make it difficult to pass the wire when a number of connections is required.

5. If the DCPM option has been ordered, insert connectors J5 and J6 in their respective places.

6. Slide the back support in place and tighten the screws. Connectors should not move at this point. The support must enter in the groove provided at the back of each connector in order to block them in place.

Figure 38 - Inserting connectors J5 and J6


46

7. Make the necessary connections for this row.

Note: If you wish to fix the wires that come out of the unit, it is recommended to use cable fixtures that will be attached to the pull handle.

To add a connection or to make changes to connectors J1 to J4, it is necessary to retrieve connectors J5 and J6. To do so, pull firmly to extract both connectors together. Be careful not to make any up exaggerated up-and-down or left-to-right movements.

Figure 39 – Wiring installation suggested

5.6 Step 6: Power the Unit

Apply power to the unit. The green LED on the front panel should turn on, indicating that proper power is fed to the iS³.

5.7 FINAL VERIFICATIONS

It should be good practice to verify that all physical inputs and outputs are correctly plugged in. To do so, you need to verify that your unit is properly configured and also read physical inputs from the iS³ in order to verify that the readings are correct.

iS3 – INTELLIGENT SMALL SITE SUPERVISOR CONFIGURATION

47

6 CONFIGURATION

The iS³ must be properly configured. That is, configuration files must be present in the internal file system of the iS³. Configuration is required not only to give the iS³ the correct definition of derived channels, but also to configure real channels, which measure real inputs, and to set communication parameters and login access information.

6.1 CHECKING FOR CONFIGURATION

The iS³ is always shipped with a pre-loaded default configuration. This way, no configuration process is needed at installation.

The simplest way to check if all the required configuration files are properly loaded into the device is to use the iS³’s Web interface. Reading all the inputs will not only confirm that your installation is good, but it will also confirm that the channels you intend to use are properly configured.

6.2 VIEWING RESULTS

There are two (2) ways to view results on the iS³, through the Web interface or downloading the chan.csv file using FTP.

Figure 40 - FTP interface

To access the iS³ and to view results, you have to connect through a PPP with the iS³, see the PPP connection procedure in the User’s Guide. If through the PPP connection you can’t yet view results, then you can use the following procedure:


48

1. Connect a UTP cable designed for direct connection (usually yellow) between the iS³ and your computer.

2. Configure a proper IP address in your computer; remember that this address has to be in the same subnet than the iS³ IP address.

Once connected, use your browser to connect to the iS³ or download the chan.csv file using FTP. For the Web browser, be sure that no Proxy is configured in your computer.

To perform this verification through the Web, click on the desired hyperlinks of the iS³-3SH section of the interface. This will display the Web page showing all real channels related to the selected hyperlinks (Hardware). You can check all binary inputs as well as analog inputs. Just scroll through the page to verify each input.

Figure 41 - Web interface, channels page


49

To perform this verification through FTP,

1. Download the chan.csv file.

2. Open the chan.csv file.

If you encounter problems reading some of the inputs, the usual causes are:

- Configuration files are missing.

- Your wiring does not correspond to the actual configuration for input channels.

In order to verify that you have configuration files loaded into the device, you may use FTP to log into the iS³ and check the presence of the configuration files.

The following list shows how the 3 configuration files should appear after logging in using FTP and typing the “dir” command. The files you need are the 3 “*.XMD” files:

CFG_APP.XMD

CFG_ACC.XMD

CFG_DEV.XMD

53

8 ANALOG INPUTS CALIBRATION

This chapter will guide you through the simple process of calibrating analog input channels.

Analog input channels are accurately factory-calibrated before shipping. This operation is usually not required when installing new units.

8.1 CALIBRATION PROCEDURE

Using the Web interface, click the link just below categories and scroll down at the end of the page.

Note: You should have supervisor rights (logged in as supervisor) to get access to calibration.

Figure 42 - Web interface, channel page, analog channel section

Click on the calibration icon ( ) to get access to the calibration page of the corresponding channel. The following page will then appear.

iS3 – INTELLIGENT SMALL SITE SUPERVISOR ANALOG INPUTS CALIBRATION

54

Figure 43 – Web interface, channel calibration

Simply follow the step-by-step procedure to adjust the “zero” and correctly calibrate the channel. You should use a calibrated multi-meter to have a precise reading of the actual signal you apply to the channel input pins. This reading should be entered as the known input value.

To properly calibrate the unit, it is important to apply a value to the inputs pins that is at least 50% of the full scale. For example, for a 70Vdc type input, using a voltage of about 50Vdc for calibration is good practice.
