GENERAL DESCRIPTION

The IAMS3535 Smart Analog to MODBUS Conditioner with Alarms

module accepts a wide range of DC analog process signals There are eighteen

different DC analog input ranges which determine the input span and type The

input accepts a maximum of 110 VDC and 110 mA DC

The IAMS converts an analog input signal into a register format that can be

read using ASCII or RTU MODBUS protocol With the features of gain and

offset, the input signal can be scaled to meet process requirements Additionally,

two setpoint values can be entered for dual relay process monitoring alarms

The IAMS is programmed with Windows™ based SFIMS software The

software allows configuration, calibration, and storage of IAMS program files

Additionally, all setup parameters can be interrogated and modified through

MODBUS register and coil commands

The RS485 port allows the IAMS to be multidropped, with Baud rates up to

38400 The CBPRO007 programming cable converts the RS232 port of a PC to

RS485, and is terminated with an RJ-11 connector The bidirectional capability

of the CBPRO007 allows it to be used as a permanent interface cable as well as

a programming cable

The IAMS’s two Form A relay alarms can be configured independently for

absolute high or low acting with balanced or unbalanced hysteresis Alarm 2 can

also be configured for deviation and band alarms In these modes, Setpoint 2

tracks Setpoint 1 Adjustable alarm trip delays can be used for delaying output

response The alarms can be programmed for Automatic or Latching Latched

alarms must be reset via serial command A standby feature supresses the alarm

during power-up until the process stabilizes outside the alarm region Standby

eliminates power-up tripping for low acting alarms The output relays can also

be manually controlled via register commands

The module’s high density packaging and DIN rail mounting saves time and

panel space The module is equipped with a universal mounting foot for

attachment to standard DIN rails, including top hat (T) profile or G profile rail

BLOCK DIAGRAM

WIRING CONNECTIONS

All conductors should meet voltage and current ratings for each terminal

Also, cabling should conform to appropriate standards of good installation,

local codes and regulations When wiring the module, use the numbers on the

label to identify the position number with the proper function Strip the wire,

leaving approximately 1/4" (6 mm) of bare wire exposed Insert the wire into

the terminal, and tighten the screw until the wire is clamped tightly (Pull wire

to verify tightness ) Each terminal can accept up to one #14 AWG (2 55 mm),

two #18 AWG (1 02 mm), or four #20 AWG (0 61 mm) wires

MODULE POWER CONNECTIONS

Module power is connected to terminals 1 and 2 For best results, the power

should be relatively “clean” and within the specified limits Drawing power

from heavily loaded circuits or from circuits that also power loads that cycle on

and off should be avoided It is recommended that power supplied to the module

be protected by a fuse or circuit breaker

INPUT CONNECTIONS

Current Input

Wiring for a current input is

connected to terminals 10 (+) and 12 (-)

Terminal 10 (+): 100 mA

Voltage Input

Wiring for a voltage input is

connected to terminal 12 (-) and one of

the voltage terminals listed below

Terminal 7 (+): 1 VDC max

Terminal 8 (+): 10 VDC max

Terminal 9 (+): 100 VDC max

RELAY OUTPUT CONNECTIONS

There are two Form A output relays The wiring for Relay 1 is connected

between terminals 5 and 6 The wiring for Relay 2 is connected between

terminals 3 and 4

To prolong contact life and suppress electrical noise interference due to the

switching of inductive loads, it is good installation practice to install a snubber

across the contactor Follow the manufacturer’s instructions for installation

Note: Snubber leakage current can cause some high impedance loads to be held

ON.

DEFAULT SERIAL SETTING CONNECTION

If the IAMS settings are unknown, or forgotten, they can be reset to the

factory defaults by connecting the Serial Default terminal 11 to Input Comm

terminal 12 with a jumper, and then cycling power

DEFAULTS:

RS485 SERIAL CONNECTIONS

STEP 1 WIRING THE MODULE

Protocol: RTU

Address: 247

Baud Rate: 9600

Data Bits:

Parity:

none

Although this unit is designed with a high degree of immunity to Electro-

Magnetic Interference (EMI), proper installation and wiring methods must be

followed to ensure compatibility in each application The type of the electrical

noise, source or coupling method into the unit may be different for various

installations Cable length, routing, and shield termination are very important

and can mean the difference between a successful or troublesome installation

Listed below are some EMC guidelines for successful installation in an

industrial environment

1 Use shielded (screened) cables for all Signal and Control inputs The shield

(screen) pigtail connection should be made as short as possible The

connection point for the shield depends somewhat upon the application

Listed below are the recommended methods of connecting the shield, in order

of their effectiveness

a Connect the shield only at the rail where the unit is mounted to earth

ground (protective earth)

b Connect the shield to earth ground at both ends of the cable, usually when

the noise source frequency is above 1 MHz

c Connect the shield to common of the unit and leave the other end of the

shield unconnected and insulated from earth ground

2 Never run Signal or Control cables in the same conduit or raceway with AC

power lines, conductors feeding motors, solenoids, SCR controls, and

heaters, etc The cables should be run in metal conduit that is properly

grounded This is especially useful in applications where cable runs are long

and portable two-way radios are used in close proximity or if the installation

is near a commercial radio transmitter

3 Signal or Control cables within an enclosure should be routed as far away as

possible from contactors, control relays, transformers, and other noisy

components

4 In extremely high EMI environments, the use of external EMI suppression

devices, such as ferrite suppression cores, is effective Install them on Signal

and Control cables as close to the unit as possible Loop the cable through the

core several times or use multiple cores on each cable for additional

protection Install line filters on the power input cable to the unit to suppress

power line interference Install them near the power entry point of the

enclosure The following EMI suppression devices (or equivalent) are

recommended:

Ferrite Suppression Cores for signal and control cables:

Fair-Rite # 0443167251 (RLC # FCOR0000)

TDK # ZCAT3035-1330A

Steward # 28B2029-0A0

Line Filters for input power cables:

Schaffner # FN610-1/07 (RLC # LFIL0000)

Schaffner # FN670-1 8/07

Corcom # 1 VR3

Note: Reference manufacturer’s instructions when installing a line filter.

5 Long cable runs are more susceptible to EMI pickup than short cable runs

Therefore, keep cable runs as short as possible

EMC INSTALLATION GUIDELINES

STEP 4 PROGRAMMING THE INPUT

The IAMS receives an analog input, converts it to a raw digital value, and stores this number in the ADC Value (register 40001) This number is scaled

into engineering units using the Gain Value (register 40010) and Offset Value (register 40011) The result of this scaling is stored as the Process Value

(register 40002) It is also stored in the IEEE 754 Standard 32-bit floating decimal format (register 40003 and 40004) The non-scaled ADC, the scaled

Process value, or the Floating point value may be accessed for the purpose of monitoring the input level

Input Range: Select the desired input range from the pull down menu

Gain & Offset: The Gain & Offset values are used to scale the input signal into

engineering units The result is stored in the Process Value register To determine the

Gain and Offset for your application, use the Scaling Wizard button

STEP 3 PROGRAMMING - Getting Started

Run RLCPro by double-clicking the icon, or use the start menu

Use the FILE pull-down menu

to select a NEW file

You will be prompted to

select the proper device,

and then the model

STEP 2 INSTALLING SFIMS Software for Intelligent Modules)

Insert the SFIMS diskette into the A: or B: drive Then Run

A:\SETUP (or B:\SETUP) to install RLCPro onto the hard drive An

icon labeled RLCPro will be created under the group RLCPro

Filter Response: The Filter Response is a time constant, in tenth of second increments, that is used

to stabilize an erratic input The Process value stabilizes to 99% of the final value within

approximately 5 time constants A value of ‘0’ disables digital filtering

Filter Band: Filter Band is a value expressed in Process units When a fluctuating signal remains

within the band value, the Digital Filter is active, and therefore stabilizes the Process Value

When a fluctuating signal exceeds the Filter Band value, the Digital Filter is momentarily

disabled to allow for a quick response to valid process changes Once the signal variation is less

than the Filter Band value, the Digital Filter is reactivated

The Scaling Wizard prompts you to enter four values Simply key in the Minimum and

Maximum signal Input Values, and the desired Process Value equivalents Press the Next

button to calculate the new Gain and Offset values

Note: The Process Values must be between –32000 and +32000. (negative values will be

transmitted as 2’s complement)

Once the Next key is pressed, the software will display the new Gain and Offset values

It will also display the exact Process Value result for your input signal The Process values

may be different than those previously entered due to the resolution of the Gain and Offset

values Press the Accept button to have the Gain and Offset values entered into the Input

Setup screen When a download is performed, the Gain and Offset values are written to

registers 40010 and 40011 respectively

STEP 5 PROGRAMMING THE ALARMS

Action: Alarm 1 can be programmed for 5 modes of operation, Alarm 2 has 8 possible modes

Manual: In Manual mode, the Alarms are forced on and off by writing ‘0’ or ‘1’ to the appropriate

MODBUS register (Alarm 1 state = 40024, Alarm 2 state = 40025)

Absolute HI: (with balanced or unbalanced hysteresis) The Alarm energizes when the Process exceeds the

Setpoint Limit Value

Absolute LO: (with balanced or unbalanced hysteresis) The Alarm energizes when the Process falls below

the Setpoint Limit Value

Deviation HI, Deviation LO, Band Outside: In these modes, Alarm 2 “tracks” Alarm/Setpoint 1 (See

Setpoint ALarm Figures below )

Setpoint: The Alarm setpoint, entered in scaled Process units

Hysteresis: Hysteresis is used to eliminate output chatter The Hysteresis Amount is the difference between

the points that an Alarm will “turn on” and “turn off” In Unbalanced modes, the alarm turns on at the

Setpoint, and turns off at Setpoint-HYS for HI alarms, and Setpoint+HYS for LO alarms In Balanced

modes, the Hysteresis is evenly divided above and below the Setpoint value (See the Setpoint Alarm

Figures below) The software calculates the hysteresis percentage and displays it for you

Note: The Setpoint, along with the Hysteresis, MUST NOT produce a “trip point” higher than 32,000, or

less than -32,000. (See the Setpoint Alarm Figures below)

Reset:The alarms can be programmed for Latched or Automatic In Automatic mode, an energized alarm

turns off by itself once the Process leaves the alarm area In Latched mode, an energized alarm requires

a serial reset This is done by writing a ‘0’ to the appropriate MODBUS register (Alarm 1 state = 40024,

Alarm 2 state = 40025)

On Delay: The time, in whole second increments, that the alarm will take to energize when the Process

Value crosses into an alarm state area

Enable Standby Delay: Standby prevents nuisance (typically low level) alarms after a power up After

powering up the unit, the Process must stabilize outside the alarm region Once this has occurred, the

standby is disabled, and the alarm responds normally until the next module power up

STEP 6 PROGRAMMING THE IAMS COMMS PORT

The IAMS’ serial port must match the device being used to communicate to it

MODBUS Protocol: RTU or ASCII

Unit Address: 1-247

Baud Rate: 300, 600, 1200, 2400, 4800, 9600, 19200, or 38400

Data Bits: 7 or 8

Parity: odd, even, or none

Transmit Delay: Programmable from 1-255 milliseconds The Transmit Delay is the time the IAMS

will wait to respond to a serial command, UNLESS the values in the table below are larger

Note: If the Unit Address, Protocol, Baud rate, etc. are

changed, and then a download is performed, the unit

will now respond to the new settings. Any further

attempts to communicate to the module must target

the new address, with the new settings.

The IAMS’ serial settings must match the device that

it is communicating with. If you do not know or

cannot recall the IAMS settings, they can be reset

back to factory defaults. Simply jumper the Serial

Default terminal to Common, and cycle power. The

serial settings will default to RTU mode, 9600 baud,

8 data bits, no parity, with an address of 247.

Go to the SETTINGS pull-down menu, and select PC PORT SETTINGS

The Communications Settings window allows you to set up the software properly to perform a download

Connection: Select the computer port (COMM 1-4) that the IAMS is connected to

NOTE: The following settings must match the IAMS. If you do not know or cannot recall the IAMS settings, they

can be reset back to factory defaults. Simply jumper the Serial Default terminal to Common, and cycle power.

The serial settings will default to RTU mode, 9600 baud, 8 data bits, No parity, with an address of 247.

Protocol: RTU or ASCII

Unit Address: 1-247

Baud Rate: 300, 600, 1200, 2400, 4800, 9600, 19200, 38400

Data Bits: 7 or 8

Parity: odd, even, or none

Connect the IAMS to the computer with the CBPRO007 interface cable (or any suitable RS232/RS485 converter) Apply 18-36 VDC to the supply terminals of

the IAMS

Note: The CBPRO007 download cable DOES NOT typically require power. In most cases it will derive its power from the PC. If communications

can not be established, follow the troubleshooting guide. If it is determined that the converter requires power, attach a 12 VDC power supply to

the VDC and common terminals of the cable.

STEP 8 DOWNLOADING

Go to the FILE pull-down menu, and select DOWNLOAD

The following screen prompts you to

ensure that the proper file is downloaded

to the correct module Click “OK” to

continue

The IAMS is fully calibrated from the factory Voltage or Current range calibration is recommended

every two years Internal ADC calibration is not recommended unless the voltage or current values are

still incorrect after their calibration If the ADC calibration is performed, the voltage or current

calibration must be performed Each input range has its’ own minimum and maximum ADC references

(registers 40005 and 40006) which are recalled when the range is selected This allows independent

calibration for the desired range Calibration may be performed via MODBUS commands, or by using

SFIMS software

Allow the IAMS to warm up for 30 minutes minimum, and follow the manufacturer’s warm-up

procedure for the calibration source

Note: Calibration requires a precision signal source with an accuracy of 0.025%, and must be capable

of generating the full span of the range to be calibrated. hen using SFIMS for calibration, connect

the signal source to the IAMS, select the proper range in the software, and press the Calibrate button.

Follow the calibration procedures in the software.

INSTALLATION

The unit is equipped with a universal mounting foot for attachment to standard DIN style mounting rails, including G profile rail

according to EN50035 - G32 , and top hat (T) profile rail according to EN50022 - 35 x 7 5 and - 35 x 15 The unit should be installed in a

location that does not exceed the maximum operating temperature and provides good air circulation Placing the unit near devices that

generate excessive heat should be avoided

G Rail Installation

To install the IAMS on a “G”

style DIN rail, angle the module

so that the upper groove of the

“foot” catches under the lip of the

top rail Push the module toward

the rail until it snaps into place

To remove a module from the

rail, push up on the bottom of the

module while pulling out and

away from the rail

T Rail Installation

To install the IAMS on a “T”

style rail, angle the module so

that the top groove of the “foot”

is located over the lip of the top

rail Push the module toward the

rail until it snaps into place To

remove a module from the rail,

insert a screwdriver into the slot

on the bottom of the “foot”, and

pry upwards on the module until

it releases from the rail

APPLICATION

Untreated waste needed to be pumped up a hill to a treatment

center To prevent undesirable shut downs, a backup pump and

a flow transducer were installed in the line The operator

needed the ability to monitor the flow, as well as the ability to

change setpoints from the main station, located 4000 feet away

The temperature within the pumping station was not controlled

The IAMS was installed because of the size, operating

temperature range, serial communications, and the ability to

control the pumps When the flow is below a certain level, the

IAMS switches the Main Pump off, and the Backup Pump on

Operators can monitor the flow and change the setpoints from

the main building using a PC acquisition program with a

MODBUS driver
