1. TECHNICAL DETAILS This is a versatile micro-controller based Scanner with a very high performance to price ratio. The features offered in this product are better than any other Scanner available in similar price range. The instrument is made in 96x192x208 mm size with standard cut out of 92x188 mm. Front is sealed membrane type to withstand dusty environment. On back plate PCB soldered 37 pin D type terminals of very good quality are used. The programming and calibration operation of the instrument is by nine simple keys with two independent displays for channel no and data value for that channel. Channel display is of two digit to differentiate it from data display of four digit, each of 0.56" seven segment LED. Status of Run/ Program/Verify mode, Fault, Auto/Manual mode Operation of the instrument is menu driven with user understandable prompts. Provision for PASS WORD is kept for unauthorized access to critical configuration and program parameters. The product is made to accept Linear voltage inputs. The type of input can be changed in field also. The calibration of the unit is done without trim-pots. The unit can be calibrated in installed condition itself by front panel keys at any given point i.e. user do not required to feed a fixed signal. No. of Groups as well as no. of channels within the group are programmable. Set point type ( LL, hL or hh ), abnormal status ( Alarm or Trip ) for alarm limit1 and alarm limit 2 as well as Relay action type ( ON or OFF ) for alarm limit 1 and alarm limit 2 are programmable. For each group two relays are given for one alarm limit 1 and second alarm limit 2. Scan time is programmable up to 99 seconds with + 30% error.. Relay on time is programmable up to from 0 to 5 minutes with + 30% error.. Provision for zero and span setting is made to restrict range of usage and programming. This restricts accidental wrong setting of set point beyond the range of interest. This zero and span setting is more useful for linear inputs for setting the range between -1999 to 9999 counts. Serial Communication with RS 232 / RS 485 is also provided for using the scanner as backend for Supervisory Control or for P.C. connectivity. Standard protocol for communication used is “MODBUS-RTU”.

3. USER GUIDE

3.1. INTRODUCTION This is a single chip micro-controller based scanner designed for 0 – 10V DC linear input type. Instrument is operated by nine user friendly keys. These keys are used for operation, programming and calibration. There are four levels of protections in the instrument. The four levels decide access to verify settings(operator level), access to set points & control parameters(supervisor level), configuration and calibration. The manual covers all aspects of operation of the instrument. Please read instructions carefully before altering any programming or configuration information.

3.2. OPERATION

3.2.1. POWER SUPPLY Always be sure that you are connecting right input supply voltage to right power terminal of the instrument. The instrument is having 4 terminals 110- 230V – Neutral and Earth for mains Supply. On application of proper power, the instrument will display Scanner type for 2 seconds and then configuration type for another two seconds. Now, if the input signal is connected, scanner will display value of input in DATA window and channel no. in channel window on display along with appropriate mode LED.

3.2.2. KEY BOARD

There are nine keys for operation of the instrument. For understanding the operation first let us see the operation of keys.

3.2.2.1. VFY This key is used to select desired parameter in configuration , program , verify configuration and verify program modes. On first press of this key, it will display

md CnFG

By pressing inc or dec key you can select the desired mode( CNFG, PRGM, VCFG, VPGM) of operation. Now if you again press the vfy key then the instrument will come in Run mode. The corresponding mode LED will glow on pressing this key.

3.2.2.2. ENTER/ACK



Issue No : 01A/600787

This key is used to enter the value of the selected parameter. After setting the data to proper value, if ENTER key is pressed, the data will be permanently stored in non-volatile memory. On pressing of ENTER key, the decimal point on last digit disappears to indicate that data is entered. Now, the data change is not allowed until ENTER key is pressed once again. On pressing of ENTER key once again, decimal point on last digit will glow and allow change in the data. This key when pressed during RUN MODE will be taken as a ACK key which is used to acknowledge the relays and LED status as per logic selected.

3.2.2.3. INC ( σ ) This key will increment the selected parameter value by one count in program ,configuration or calibration mode. if you keep pressed the key then value will be incremented by 10 times faster up to the maximum value of that particular parameter.

3.2.2.4. DEC ( τ )

This key will decrement the selected parameter value by one count in program or configuration mode. if you keep pressed the key then value will be decremented by 10 times faster up to the minimum value of that particular parameter.

3.2.2.5. NEXT This key is used to move into next parameter in a current mode. When pressed in Run mode, the next un-skipped channel will be displayed. Normally it is used in MAN mode to select next channel for fixed channel display.

3.2.2.6. AUTO/MAN This key is used to set the unit in either auto mode or manual mode. This is a toggle key. i.e. if it is pressed in auto mode, the unit is switched into MAN mode and channel display will become fixed. MAN LED will glow in MAN mode to indicate the same. This key is also used for individual zero/span, individual input type and individual decimal point position setting, for each channel.

3.2.2.7. SCN TIME This key is used to set the scan time for display of channels and its reading. It can be incremented up to 99 using INC key or decremented up to 1 using DEC key. This key is also used to enter in calibration mode from configuration mode and also to set the Relay time for setting on time of relay.

3.2.2.8. SKIP / SCHK KEY This key is used to skip / un-skip the channel in program mode. This is also a toggle key. i.e. if key is pressed while channel is skipped, it will un-skip the channel. On pressing this key in program mode, skip / un-skip message will be displayed in Data window and channel no. will be displayed in Channel window.

3.2.2.9. AL1 / AL2 This key is used to change from alarm limit 1 to alarm limit 2 and vice-versa. This is also a toggle key.

3.3. MODES OF OPERATIONS

3.3.1. There are seven modes of operations.

3.3.2. Run mode 3.3.3. Auto / manual mode 3.3.4. Verify program mode 3.3.5. Program mode 3.3.6. Configuration mode 3.3.7. Verify configuration mode 3.3.8. Calibration mode

Each are described in detail in individual chapter

4. RUN MODE This mode is indicated by RUN LED glowing. In this mode, channel window will display current channel number and DATA window will show its temperature. In AUTO mode, it will keep on displaying successive un-skipped channels at the programmed scan rate. In case of MAN mode, only one channel will be displayed continuously. For manual mode separate LED indication of mode is provided on front. The relay of that channel will be turned OFF, on acknowledging the alarm, if the alarm type is not configured for trip logic, where relay is not turned OFF until it actually comes within limit. The type of action and normal status of relay is programmable and described in Configuration mode. Also refer relay logic table For currently selected calibration channel decimal point on unit's digit of channel no. will glow.

5. MANUAL MODE Manual mode is same as normal run mode except for displaying only one channel continuously. The channel number can be changed by NEXT key. This mode is entered by pressing AUTO/MAN key in RUN/AUTO mode. Pressing this key once again brings back to AUTO mode.

6. PROGRAM MODE This mode is used to display / change alarm limits, scan time and skip status of channels. For entering in this mode, press VFY key in RUN mode and VFY LED will glow to indicate the mode selection and display will ask to select the mode. By pressing increment and decrement key select PRGM option and press ENTER key. By pressing the ENTER key it will ask for Password . Select your password by using “INC” and “DEC” keys.If the Password is correct then it will go in to Program mode and PRG LED will start glowing to indicate the current mode of operation.

13. Trouble shooting

Scanner does not Switch ON.

• Check the Mains Cord. • I/P power may be not present. Check power supply voltage is it proper as per order • Check fuse, if blown off replace it • Check the Power ON Indication LED.

Calibration of the unit is doubted to have drifted.

• Check the O/P of sensor is as per the chart supplied to you by sensor manufacturer. Measure it with

instrument with better then 0.1% accuracy. Standard multi-meter with 3½ digit display may have poor accuracy then scanner.

• Calibrate the unit as explained in the manual. Select the proper method according to your scanner input type.

In linear type input the unit shows false reading or ‘OVER’ or ‘UNDER’.

• Check for the polarity of the I/p connections. • Check for the proper range programmed in that channel.

Reading indicated by scanner is unstable, wrong or open.

• Check the process input and also check its connection are as per the back-plate supplied. • Ensure the perfect EARTHING to the unit & also check that neutral should not be floating. • Shielded cables should used for input. Shield should be EARTHED near the unit only. • Check any of the sensor is not getting EARTHED or having weak insulation with respect to earth. If so,

remove that sensor and check the cabling. • Check that Input cables are properly tighten with back-plate • Check that back-plate is not loose. • Take separate earth wires for separate instruments, avoid looping of earth wires. • If scanner is showing different reading in all channels for common I/P type and same Process vale then

please enter I/P type again. • Check for AC voltage pick up at the signal at scanner side • All low-level input and output such as T/C, Rtd, Linear I/P and control signal wires must be kept

separate from supply and relay output cabling. Communication Problem between the Unit and Host PC/Operator Terminal

• Check the cabling. • Check the serial No. and baud rate settings at PC side and scanner side. • Check the RS-485 to RS232 converter for 485 communication. • Check the serial port of the computer by shorting 2 and 3 no pin of PC comports with PROCOMM or

any other available application.



Issue No : 01A/600787

• Check RS 232 –RS 485 connection at PC and scanner side. • For RS 485 sometimes terminating resistor of 120Ω at scanner and converter side. In most of the cases

this is not required for scanner. Relay or open collector O/P Action problem

• Check power to the contactor operated by relay from scanner. • If relay card or open collector card burns out frequently check for the rating of the relay driven by open

collector card or rating of contactor driven by relay card.

General • It is mandatory to reset the Instrument by switching off the Power if the input type is changed. • In Configuration, Program, Verify Configuration, Verify Program and Calibration modes, 20 Sec time out is

provided i.e. if no key is pressed for 20 seconds, it will fall back into Run/Man mode. • While programming value, if the INC or DEC key is kept pressed for more than 10 counts, the

speed of change will be increased by 5 times. It is the dual speed concept for changing value at faster rate. • On power on scanner will first display model (8508/8516/8524), then configuration type for some time and

then it will come to actual Run mode display. • If there is any error in EEPROM data, it will display error message and halt.

10 -Err

• The upper two digit display will show no. of parameters having errors and lower 4 digit display will show -err message. To see the parameter having error, scan through parameters both in Program mode & Configuration mode. The decimal point of first digit of channel no. display will glow, if the parameter data in EEPROM is disturbed.

• If you change any individual I/P type or common I/P type then please also adjust your particular channel span value, Zero value and alarm-trip set-points.

SUPPLY VOLTAGE

• Supply voltage should be given through a good isolation transformer. This being a microprocessor based instrument, a massive voltage spike can damage it. A good isolation transformer shields the instrument from such voltage spikes and surges.

• All supply connections to final control devices such as contractors, solenoids etc. must be taken directly from the supply and not from the supply terminals of the instrument.

• An effective earth is mandatory for the instrument. I n absence of proper earthing instrument body will float at half some part of the supply voltage and this may give shock to user.

This is an electronics instrument it may have problem not listed above, in case of such fault while reporting to factory (Masibus area office or head office), mention exact nature of fault with sequence of events.

14. Modbus detail

14.1. INTRODUCTION

The scanner 85XX can be connected in RS-485 communication data link either in multi drop or repeat mode. Each scanner 85XX must have unique Serial Number. No two scanners may have the same address. Entire range of addresses ( 1 to 99 ) may be used. Before starting any communication, choose a baud rate and protocol compatible to the host computer. Only two-pass protocol is available on scanners and hence when using the scanners, only two-pass protocol is assumed. This speeds up the total throughput.

14.2. COMMUNICATION PROTOCOL The communication protocol is a HEX protocol. The host computer issues the commands to the scanners that in turn respond to each command. The entire protocol is based on the command/answer protocol.

14.2.1. How Characters are Transmitted Serially

When messages are transmitted on standard Modbus serial networks, each character or byte is sent in this order (left to right): Least Significant Bit (LSB) ... Most Significant Bit (MSB)With RTU character framing, the bit sequence is:

i.e. 1 start bit 1 stop bit No parity.

14.2.2. MESSAGE QUERY:



Issue No : 01A/600787

14.2.3. RTU Framing

14.2.4. START DELAY and ADDRESS:

Always contains the start of message with 3.5 null char delay followed by the address of the scanner to be addressed. The address is represented by a HEX character ranges from 00 to 99.

14.2.5. FUNCTION: When a message is sent from a master to a slave device the function code field tells the slave what kind of action to perform. In scanner 85XX the functions implemented are 01– READ COIL STATUS (REFERENCE - 0x). 05. – FORCE SINGLE COIL (REFERENCE - 0x). 03. – READ HOLDING REGISTERS (REFERENCE- 4x). 06. – PRESET SINGLE REGISTER (REFERENCE - 4x). Here Same Reference Functions are used for Reading and Writing a parameter, so only one Variable Tag is required for reading and writing a parameter.

14.2.6. DATA FIELD:

Read : The query message specifies the starting register and quantity of registers to be read. Registers are addressed starting at zero- registers 1 ... 12 are addressed as 0 ... 11. The quantity of channels must not exceed ( total no of channels – starting channel address). Write : The query message specifies the register address and the data to be written in that register. Registers are addressed starting at zero- register 1 is addressed as 0.



Issue No : 01A/600787

14.2.7. CHECKSUM COMPUTATION: The error checking field contains a 16-bit value implemented as two eight-bit bytes. The error check value is the result of a Cyclical Redundancy Check(CRC) calculation performed on the message contents.

14.2.8. CRC calculation: The CRC field checks the contents of the entire message. It is applied regardless of any parity check method used for the individual characters of the message. The CRC value is calculated by the transmitting device, which appends the CRC to the message. The receiving device recalculates a CRC during receipt of the message, and compares the calculated value to the actual value it received in the CRC field. If the two values are not equal, an error results. The CRC is started by first pre loading a 16-bit register to all 1's. Then a process begins of applying successive eight-bit bytes of the message to the current contents of the register. Only the eight bits of data in each character are used for generating the CRC. Start and stop bits, and the parity bit, do not apply to the CRC. During generation of the CRC, each eight-bit character is exclusive ORed with the register contents. Then the result is shifted in the direction of the least significant bit (LSB), with a zero filled into the most significant bit (MSB) position. The LSB is extracted and examined. If the LSB was a 1, the register is then exclusive ORed with a preset, fixed value. If the LSB was a 0, no exclusive OR takes place. This process is repeated until eight shifts have been performed. After the last (eighth) shift, the next eight-bit byte is exclusive ORed with the register's current value, and the process repeats for eight more shifts as described above. The final content of the register, after all the bytes of the message have been applied, is the CRC value. When the CRC is appended to the message, the low-order byte is appended first, followed by the high-order byte.
