INSTRUCTION MANUAL

1 INTRODUCTION

1.1 Product Overview

The 53IT5100B provides a suite of six operator displays to monitor process activity for up to four independent process variables and also provides integration and totalization for each of the four process variables. The displays are of three types: dynamic bar graph, digital readout, and alarm summary. There are three bar graph displays, two digital readout displays, and one alarm summary display. These include:

 Quad Bar Graph Display (Channels 1-4) 

 Two Dual Bar Graph Displays (Channels 1&2 and Channels 3&4)

 Quad Process Digital Readout Display

 Quad Totalizer Digital Readout Display

 Alarm Summary Display.

The operator displays are paged forward or back, in the order given, by pressing the F2 (page forward) or the

F1 (page back) push button on the horizontal keypad of the instrument. The operator display suite is illustrated in Figure 1-1 and the instrument horizontal keypad is identified in Figure 1-2.

Quad Bar Graph Display (Channels 1-4) - all four channels are arrayed across the display as bar graphs with the digital readout and measured units of a selected bar graph in the lower quadrant of the display. A bar graph digital readout with measured units is selected with the F3 push button, which moves a pointer to the base of each bar graph in the display every time it is pressed. In the illustration, upper and lower alarm limits appear with each 50 segment vertical axis. The measured units and alarm limits are selectable entries, as well as the mode of alarm reporting (e.g., High/Low, High only, Low only, High/Hi-Hi, Low/Lo-Lo, or none).

Dual Bar Graph Display (Channels 1&2) - two channels are arrayed across the display as bar graphs with the digital readout and measured units of each channel appearing beneath its bar graph. The channel tag names appear in the upper quadrant of the display. Each 50 segment vertical axis has a numeric range and alarm limits. The tag names, vertical axis numeric range (zero and span), measured units, alarm limits, and alarm mode are all selectable entries.

Dual Bar Graph Display (Channels 3&4) - is identical to Dual Bar Graph Display (Channels 1&2) except it displays process activity from channels 3 and 4.

Quad Process Digital Readout Display - is a process activity digital readout of all four channels that is refreshed every second. The display is divided vertically into four quadrants, each one dedicated to a channel. Each channel readout has a tag name, numeric value, and measured units field. The tag names and measured units are identical to those selected for the bar graph displays.

Quad Totalizer Digital Readout Display - is an integrator accumulator digital readout of each of the four channels that is refreshed every second. The display is divided vertically into four sections, each one dedicated to a channel. Each channel totalizer has a tag name, accumulated value, and totalizer measured units field. The tag names and measured units are selectable entries.

Alarm Summary Display - presents six alarm states relevant to the four input channels and two contact inputs. The display has four partitions with the uppermost containing the display title. The word ALARM in the title flashes should an alarm condition occur with any one of the channel inputs or if a contact input is activated indicating an alarm. The specific channel or contact input in the alarm state is also differentiated from the rest of the display coincident with the ALARM banner flashing in the title of the display. The four channel inputs are listed together in the second partition, and partitions three and four are occupied by the two contact inputs. All six tag names for this display are selectable entries. There are also selectable entries that define how each contact input display message is differentiated from the others to indicate an alarm state.

As shown in Figure 1-2, the 53IT5100 contains a graphical dot matrix display; horizontal and vertical keypads; a MINI-DIN configuration port connector concealed behind the front panel pull-down door; terminals for signal

1

53IT5100B Indicator/Totalizer

INSTRUCTION MANUAL input/output wiring and power wiring; and a compact instrument case that protects the instrument main printed circuit board and internal power supply.

The display is a 96 X 48 gas discharge dot matrix, contrasted orange-on-black to enhance visibility and ease of reading. The intensity is a range selectable entry from 0 to 7, with 0 being the brightest setting (see Table

4-10).

To the right of the display is the vertical keypad and directly beneath the display is the horizontal keypad.

Both keypads have functioning push buttons that are dependent on the instrument mode of operation which can be either operator mode or engineering mode. Mode selection is made with the Mode push button on the horizontal keypad. Engineering mode is entered to make the necessary selections for the operator displays and Datalink communications port; otherwise, the instrument is left in operator mode for process applications. The vertical keypad is dedicated only to engineering mode functions and has no effect in operator mode. Both keypads are described as follows:

INSTRUCTION MANUAL

Setup of the 53IT5100B can be done using the buttons on the horizontal and vertical keypads. It can also be done via the MicroTools configuration software package, Directly beneath the horizontal keypad and concealed behind the front panel pull-down door is the RS-232 Configuration Port which accept the configuration cable that provides interface between the instrument and MicroTools running on a personal computer. The configuration functions within MicroTools are limited to loaded functions of the 53IT5100B indicator/totalizer described in this manual.

The internal power supply provides power to the main board and output power for transmitters (24-26 V dc,

80 mA total available output for instrument and transmitters).

A simplified input/output diagram of the Indicator/Totalizer is provided in the upper left corner of

Figure 1-2. As illustrated in the figure, the instrument can accept four Analog Inputs (ANI0-3) which are digitized as operands for firmware interpretation and execution (totalization). Each ANI has a square root extractor and can accept linear or squared signals of 0-20 mA, 0-5 V, 4-20 mA, or 1-5 V. Any one of the four analog inputs can be selected as the Analog Output (ANO0).

There are two contact inputs (CCI0 and CCI1 ) that have a closed recognition level of 1 V dc and open recognition level of 4-24 V dc. Each CCI indicates an alarm state, for example, a CCI can have a closed recognition level when a secondary pump is activated to support the primary pump in maintaining a proper tank level.

The totalizers provide a running total of each ANI input. The totalizers are incremented in ascending order every 0.05 seconds, but all four totalizers are refreshed on the display every second. Each ANI value can be independently adjusted by a scaling factor before being summed to the running total. The totalizer measured units, therefore, can differ from the process activity measured units as determined by the scaling factor entries for each channel. Also available as selectable totalizer entries are rollover and dropout values. The rollover value specifies a maximum positive value that causes the totalizer accumulator to reset to zero when the actual total reaches this value. An output pulse is strobed to a 1 for one scan each time the actual total reaches the rollover value. The dropout value specifies a minimum input value required to increment the running total.

All of the selectable entries for the Indicator/Totalizer are parameter entries to the database. The database is subdivided into modules composed of datapoints that are accessed by the instruction code as the instrument performs its functions. The database allows instrument functionality to be refined to specific process applications, as display attributes can be altered, input signal characteristics can be defined, each totalizer accumulated value can be flagged, and the instrument can be configured to properly match Datalink network communications requirements. A datapoint location is represented as an alphanumeric address, such as

C103, which is the location to enter the value for the ANI0 upper alarm limit that is displayed on the Quad Bar

Graph or Dual Bar Graph (Channels 1&2) displays. Datapoints are specified parenthetically in the illustration call-outs of Section 3 where the displays are described in detail. There are also illustrated procedures provided in Section 3 that show how a datapoint is displayed and configured. Definitions for all of the

Indicator/Totalizer datapoints are provided in Section 4 and listed in alphanumeric order in Appendix C.

External alarm buzzers can be activated with the contact outputs (CCO0 and CCO1). Capability limits of each

CCO are 50 mA maximum current flow when closed and 30 V dc maximum tolerance voltage when open.

Flagged conditions, such as Totalizer 0 (ANI0) rollover pulse activation, can be specified as selectable entries in the CCO module of the database. Specific details for CCO database selections are described in Table 4-6 of Section 4, and typical circuit layouts for the CCOs are described in Appendix A.

Datalink is another independent serial communications connection for the Indicator/Totalizer. It provides a permanent connection to an RS-485 multi-drop network through which a host computer can access the instrument. The Datalink connection is made at TB1 of the rear terminal board, screw lugs 19 through 22.

2 INSTALLATION

2.1 Inspection

A list of all items in the shipment is attached to the shipping container. Inspect the equipment upon arrival for damage that may have occurred during shipment. All damage claims should be reported to the responsible shipping agent before installation is attempted. If damage is such that faulty operation is likely to result, the

MicroMod Customer Service Department should be notified.

Inspect the packing material before discarding it as a precaution to prevent loosing mounting hardware or special instructions that may have been included with the shipment. Normal care in the handling and installation of this equipment will contribute toward its satisfactory performance.

2.2 Location

The 53IT5100 is supplied with an enclosure designed specifically for indoor mounting. The installation site selected should be dry, well lighted, and vibration free. The ambient temperature should be stable and maintained within the specified minimum and maximum temperature limits listed in the Section 1, specifications of this Instruction Bulletin.

The instrument can be supplied for use with a 24 V dc supply or 120, 220 and 240 V ac line service.

Instrument power requirements are given on the instrument data tag.

2.3 Mounting

2.3.1 General

It is normally not necessary to open the instrument case during installation. If the instrument must be removed from the case, refer to Section 5 for details. Incorrect procedures may damage the instrument.

The instrument can be flush panel mounted, either as a single unit or side by side. Appropriate mounting hardware is supplied. Outline dimensions and panel cut-out requirements for case mounting are shown in

Figure 2-1.

The dimensions given for spacing between instruments were selected on the basis of 1/8" thick panel strength. Panel strength must be considered when multiple case mounting is required. As the panel cut-out becomes longer it may be necessary to install supporting members. Because the panel area between instrument rows becomes weaker as the cut-out becomes longer to the point where the panel offers very little support. It is recommended that the 9 inch minimum center line dimension between horizontally mounted rows be increased as the number of units increases, or that the panel strip be stiffened.

The rear of the instrument case must be supported to prevent panel distortion. Mount an angle iron or similar member along the bottom of the cases as indicated in Figure 2-2. If the panel is to be moved the instrument cases must be tied down to prevent damage.

If multiple mounted instruments are installed in a panel that tilts back, it may be necessary to support the instruments so the panel does not sag. The downward weight should be supported by additional panel supports and/or by increasing panel thickness.

INSTRUCTION MANUAL

2.3.2 Mounting Procedure

For single and multiple case mounting the instruments are furnished with a trim collar (mounting frame).

Figure 2-2 illustrates the installation and use of the trim collar (mounting frame). Trim collars (mounting frames) are available in various sizes and are supplied to conform with the particular panel cut-out.

NOTE: Mounting brackets and trim collars (mounting frames) are packaged separately. Check the shipment carefully to prevent loss of mounting hardware.

To install single or multiple mounted instruments in a prepared panel cut-out, proceed as follows:

1. Remove the through-case shipping bolt.

2. Slip the trim collar (mounting frame) over the rear of the case and slide it forward to the front of the case.

3. Slide the instrument case through the panel opening. a. Single mounting case - support the weight of the case and attach the top and bottom mounting brackets. Tighten the bracket screws. b. Multiple mounted cases - spacer bars and self-adhesive pads must be used between the cases, as shown in Figure 2-3. Start the installation from the right (when facing the panel), installing the spacers as each case is added. Also, as each case is positioned in place, install and tighten the top and bottom mounting brackets. Each case must be tight against the previous case.

NOTE: Spacers are not required on the outside of the right and left cases.

2.4 Power & Signal Wiring

PREPARATORY: The 53IT5100B can be configured for one to four analog inputs (ANI0-3), one analog output (ANO0), two control contact inputs (CCI0 and 1), two control contact outputs (CCO0 and 1) and

Datalink network interconnectivity. Therefore, prior to making electrical connections, the particular instrument configuration should be determined with all assigned inputs and outputs identified to assure proper signal routing.

Provisions for electrical interconnections are located at the rear of the instrument case. Under ideal conditions shielded cable may not be required. In noisy locations all system input, output and power wiring should be enclosed in electrical conduit. System interconnection cables (except for power cables) should be fabricated from 2-wire shielded signal cable. Signal transmission distance should not exceed the limit specified for the particular transmitter (refer to applicable technical literature provided for the respective device). Polarity must be observed when connecting the remote transmitters to the instrument.

The instrument has a vertically mounted terminal strip (TB1) for signal interconnections and a horizontally mounted terminal strip (TB2) for power wiring. Both terminal strips are located at the rear terminal board of the instrument case.

SNAP-OUT TERMINAL CONNECTORS

Both terminal strips, TB1 and TB2, have removable plug-in connectors. The upper connector for TB1 has screw lugs 1 through 12 and the lower connector has screw lugs 13 through 22. All of the screw lugs are on a single connector for TB2. To remove a signal connector, grasp it securely on both sides with the thumb and forefinger, rock it gently from top to bottom (not side to side) and pull it straight out. To remove the power connector, grasp the sides firmly with the thumb and forefinger, rock it gently from side to side and pull straight out.

NOTE: The screw lugs on the back of the instrument are designed for 12 – 24 AWG wire. It is important that the wire be stripped to expose 1/2 inch of conductor before installation.

 WARNING! Instruments that are powered from an ac line service constitute a potential electric shock hazard to the user. Make certain that these system ac power lines are disconnected from the operating branch circuit before attempting electrical interconnections.

2.4.1 Power Wiring

Refer to the instrument model number to verify the power input requirements:

 53IT511nB21AAA – AC Power

 53IT512nB21AAA – DC Power

2.4.1.1 DC Power

Reference Figure 2-4 and connect the remote 24 V dc power supply to the instrument as follows:

1. Connect (+) input line, via remote SPST switch, to terminal L1.

2. Connect (-) input line to the system bus bar. The bus bar should be connected to a good earth ground (#8 AWG wire is recommended). Individual wires should be run from the controller Power

Common (PC ) and Signal Common (SC ) terminals to the bus bar. The chassis should be grounded by connecting terminal G to earth ground.

NOTE: Use of a common bus bar is recommended to minimize potential voltage differences that may occur as the result of ground current loops, e.g., potential difference between separate signal grounds, power grounds, etc.

2.4.1.2 AC Power

Reference Figure 2-4 and connect the specified line service (110-120, 220-240 V ac, 50 or 60 Hz) to the instrument as follows:

1. Connect the phase or hot line L, via a remote power disconnect switch or circuit breaker, to terminal

L1.

2. Connect the neutral line N to terminal L2 for 110-120 V ac. Connect the neutral line N to terminal L3 for 220-240 V ac.

3. Connect Power Common to a good earth ground (#12 AWG wire is recommended). The instrument case should be grounded by connecting terminal G to earth ground at the source of supply

(green/green-yellow ground).

All supply connections include surge protection rated at 275 V ac normal mode.

NOTE: To minimize possible interference, ac power wiring should be routed away from signal wiring.

2.4.2 Field Signal Wiring

2.4.2.1 Current/Voltage Input to AIN1 through AIN3

When the input signal is from a 4-20 mA current transmitter, a precision 250 ohms (+/-0.1%) resistor is required. (The resistor tolerance is critical, as the resistor is used to accurately convert the current signal from the transmitter, which is typically 4-20 mA, to a specified analog input voltage of 1 to 5 V dc). The back of the rear terminal board has the appropriate resistors (R1 and R2, respectively) for ANI0 and ANI1. Resistor for

ANI2 and ANI3 are not supplied and must be installed as shown in the upper left corner of Figure 2-4. If the input signal is already a voltage signal, its corresponding resistor should be removed.

2.4.2.2 Contact Input to CCI0 and CCI1

Separate contact input signals to CCI0 and CCI1 can be used for alarm inputs. One side of each remote contact must be connected to power common as illustrated in Figure 2-4. Minimum opened or closed recognition time for a remote contact must be 0.05 seconds.

2.4.2.3 Current Output from ANO0

A current output signal is available for re-transmission of one of the input signals ANI0 through

ANI3. Observe the proper polarity when connecting the output to another instrument.

2.4.2.4 Contact Outputs CCO0 and CCO1

Discrete contact outputs CCO0 and CCO1 are identified in Figure 2-4. Each discrete output is a solid state switch with a rating of 30 V dc, 50 mA maximum. A CCO is referenced to power common.

When this contact is connected to an inductive load, an external arc suppression network is required for contact protection.

2.4.3 Datalink Communication

Datalink is an interrogator/responder serial interface capable of supporting 32 instruments on a single network. It uses an RS485 physical interface. The Datalink wiring diagram for this instrument is provided as Figure 2-5. Complete coverage of the Datalink is provided in the SUPERVISOR-PC

Instruction Bulletin 53SU5000.

2.5 Factory Set Calibration

Each unit contains individual factory set entries that calibrate the four analog inputs (ANI0 through ANI3) and analog output (ANO0). There is a calibration sheet supplied with each instrument that should be retained for future reference when the installation is completed. Reference Section 5.3 for additional information.

2.6 Grounding

Installations are expected to have access to an independent, high quality, noise-free point of earth reference.

The system should be connected by a dedicated, low resistance (less than one ohm) lead wire directly to the installation’s point of earth reference. This ground reference is referred to as the Instrumentation Ground. If an instrumentation ground reference does not exist in the installation, an earth ground electrode should be established with an independent grounding rod or ground grid mesh.

3 DISPLAYS AND PUSH BUTTONS

This section provides illustrations with item call-outs of the six operator displays, alarm overlays, and engineering mode overlays. Where applicable, datapoints are identified parenthetically with the display item call-outs. The datapoints are defined in Section 4. The front panel push button definitions are repeated in this section from Section 1, because they are used in the engineering mode display overlay examples to enter a key password, display a datapoint, and alter a datapoint.

3.2 Alarm Overlay

Any one of the six operator displays can have the upper quadrant of the display overlaid with an ALARM indicator. An alarm indication warns of variation changes that exceed tolerance limits; the process may require immediate attention. In the five illustrations of Figure 3-7, the process variable exceeded Alarm Limit 1 for ANI1. The five illustrations show how the alarm state would manifest itself on each operator display. The alarm display for Dual Bar Graph (Chs. 3&4) is not illustrated, as the alarm banner appears in the identical manner as shown in the illustration for Dual Bar Graph (Chs. 1&2).

In the Quad Bar Graph (Chs. 1-4) illustration of Figure 3-7, the alarm banner blinks from normal to reverse video alternately with the ANI-1 graph scale (second from left). The ANI-1 graph scale does not appear in reverse video, but disappears and reappears on the display. In the Dual Bar Graph (Chs. 1&2) illustration of

Figure 3-7, the alarm banner blinks from normal to reverse video alternately with the ANI-1 graph scale (on the right of the display). The ANI-1 graph scale does not appear in reverse video, but disappears and reappears on the display. The alarm banner in the Dual Bar Graph (Chs. 3&4) operator display (not shown) would alternately blink from normal to reverse video; however, graph scales for channels 3 and 4 would be unaffected.

In the Quad Process Digital Readout illustration of Figure 3-7, the alarm banner blinks from normal to reverse video.

In the Quad Totalizer Digital Readout illustration of Figure 3-7, the alarm banner blinks from normal to reverse video.

In the Alarm Summary illustration of Figure 3-7, the alarm banner and ANI-1 tag name blink from normal to reverse video independent of one another.

The alarm banner blinking is stopped by pressing the Mode () push button on the horizontal keypad; the alarm banner remains on the display, but does not blink, until the process variable returns to a value within the alarm limit (passed dead band).

3.2.1 Front Panel Pushbuttons

The front panel push buttons are repeated here from Section 1 because they are used in the engineering mode display overlay examples to enter a key password, display a datapoint, and alter a datapoint.

To the right of the display is the vertical keypad and directly beneath the display is the horizontal keypad.

Both keypads have functioning push buttons that are dependent on the instrument mode of operation which can be either operator mode or engineering mode. Mode selection is made with the Mode () push button on the horizontal keypad. Engineering mode is entered to make the necessary selections for the operator displays and to configure the Datalink port; otherwise, the instrument is left in operator mode for process applications. The vertical keypad is dedicated only to engineering mode functions and has no effect in operator mode. Both keypads are described as follows:

3.3 Engineering Mode Overlays

The engineering mode overlays are used to make the necessary parameter entry selections for the operator displays and to configure the Datalink communications port. The entries are made to addressed datapoints via the overlay single edit line at the bottom of the display. It should be noted that engineering mode has a 20 second timeout if it is accessed and its functions (e.g., configure or display) are not used.

3.3.1 Responding to the Prompt: KEY?

When the password prompt KEY? appears, it indicates a password was set in the MicroTools software. The password can not be set via the front panel push buttons.

A password key is a maximum of 10 numeric characters (numbers 0-9 only). It does not impede display functions in engineering mode but must be unlocked to perform configuration functions. A password key is

NOT SET FOR NEW INSTRUMENTS from the factory; therefore, if it is set, it must have been done locally.

The password must first be obtained from the originator before the procedure in Table 3-1 can be used to access the engineering mode configuration function capabilities.

INSTRUCTION MANUAL

4 CONFIGURATION PARAMETERS

The configuration parameters provide the latitude to define the instrument’s personality attributes, so that while still functioning within its designed specifications, it can perform application requirements with greater refinement. Typical configuration parameters are the instrument’s indicator zero point and span, the display tag names, engineering units of the displayed process value, and alarm limits, etc. IT IS NOT NECESSARY

TO DEFINE ALL OF THE CONFIGURATION PARAMETERS, as commonly used preset values may not have to be altered and certain parameter selections eliminate others.

Although all resident in a memory database as datapoints, the configuration parameters are clustered into modular groups that may have specific hardware identities (e.g., the ANI, ANO, CCI, and CCO circuits illustrated in Figures 4-1 through 4-4), or may represent software controlled functions that are not specific to any one hardware element.

4.1 Datapoint Types

A parameter can be any one of five data types. Each data type represents a specific data format: integers, alphanumeric text strings, etc. A database module containing multiple parameters can have a mix of data types. The data types are defined in Table 4-1 as follows:

Table 4-1. Datapoint Types

Type Byte

Size

Format

L 1 Bit Represents a single binary bit that can have the value of 0 or 1.

B 1 Represents a positive integer with values from 0 to 255.

C 3 Represents a real analog (floating point) value that has a resolution of one part in

32,768 (15 bits) and a dynamic range of ± 10 38 .

H

A

5 Represents a high precision analog (floating point) value that has a resolution of one part in 2 billion (31 bits) and a dynamic range of ± 10 38 .

10 Represents a text string that can be 10 characters long.

4.2 Factory Standard Calibration

The instrument is shipped from the factory configured with all parameters set to the default values. The default values are listed in the parameter tables under the heading Default. The gray-tone shading in a default cell of a parameter indicates the contents of the datapoint are left unchanged after the database is returned to the default condition using the procedure described in Section 5.5. Examples of datapoints unaltered by default are the Calibrate Zero and Calibrate Span parameters which are factory set.

4.3 Configuring the Database Modules

The datapoints in the database modules must be changed to reflect required alterations in the factory standard configuration or when the instrument is re-configured. There are generally four datapoint parameter types contained in the eight database modules. The parameter types affect Datalink communications, display indications, input-output signals, and alarm conditions. The eight database modules are described in Table 4-

2. Although it is not an absolute criterion, it is assumed the modules will be configured in the table Item order; however, if the instrument is to be connected to a Datalink network, item 7, Communication Module, should be configured first. By configuring the Communication Module first, the instrument can function on the

Datalink and the remaining datapoint values can be entered via the Datalink interrogator (master). Reference the applicable instruction bulletin (e.g., IB 53HC3300, IB53WS5000, or IB 53SU5000) for the procedure.

Table 4-2 is also a pointer to the descriptions of the database modules; the descriptions are presented as Tables 4-3 through 4-10. (The gray tone shading in the default cell of a datapoint indicates the datapoint contents are left unchanged after default. See Section 5.5 for the default procedure.)

The value of the input is multiplied by this parameter prior to being summed to the running total. The parameter is used for both scaling and time interval integration. For example, if ANI0 is in

M gallons/day, in order to totalize in K gallons the scale factor (SF) would be:

SF = [Units Conversion] X [Time Base Conversion]

SF = [1000 K gal / M gal] X [(1 day/24 hrs) X (1 hr/60 mins) X (1 min/60 sec) X (1 sec/sample)] =

1000/86400 = 0.01157

NOTE: The time between totalizer updates is one second.

The default value of 16666 uses the scale factor for time interval integration. Due to the internal timing of the instrument, a scale factor of 16666 will cause the rollover total to occur once every minute.

5 MAINTENANCE

NOTE: The factory set calibration constants for ANI0-3 and ANO0 are applicable only for the main printed circuit board supplied in the particular instrument. This data is recorded on a calibration sheet supplied with the instrument. The data should be retained to facilitate easy field recalibration in the event one or more of the constants is inadvertently changed.

5.1 Service Approach

This instrument is a microprocessor based device; all mathematical computations, data manipulation, and sequencing operations are software controlled. After the instrument has been configured, normal operations are controlled via the front panel push buttons. Because the instrument does not have internal circuitry that requires field adjustment, diagnostic testing and preventive maintenance are not required.

Generally, when a process malfunction occurs, it usually manifests itself as an instrument problem even though it might be a defective process variable monitoring device, remote transmitter, or interconnecting wires. These associated remote devices should be checked before attempting instrument troubleshooting and repair.

Due to the complexity of microprocessor based instruments, attempting fault finding analysis to integrated circuits (ICs) on the main printed circuit board (PCB) is not recommended. The ICs are static sensitive and can be damaged if not properly handled. Also, when test probes are connected, even a momentary short across several IC pins with a probe tip can damage the IC. Therefore, only trained technicians familiar with

CMOS technology and microprocessor functionality should be permitted to service the equipment.

5.2 Parts Replacement

 WARNING: ALWAYS REMOVE POWER BEFORE ATTEMPTING TO INSTALL, DISASSEMBLE,

OR SERVICE ANY OF THE EQUIPMENT. FAILURE TO REMOVE POWER MAY RESULT IN

SERIOUS PERSONAL INJURY AND/OR EQUIPMENT DAMAGE.

Access to internal instrument parts is achieved by removing the front display panel. The front display panel can be removed by inserting a small screwdriver into the notch at the top center of the display and twisting the screwdriver to depress the retaining latch. The upper sides of the display are held and pulled forward as the latch is depressed. The cable at the rear of the front display panel is disconnected from its socket. The other cable end connects to the main printed circuit board. Replacing the display unit requires reconnecting the display end of the cable to the new front display panel, inserting the extended portion of the display panel into the instrument cabinet and latching it in place with a screwdriver.

After the front display panel is removed, the main printed circuit board can be accessed. The main printed circuit board also has the power supply as well as the microprocessor circuitry. To remove the main PCB, use its front edge board ejector to pull it free from the rear terminal board slot and carefully slide it from the case.

Disconnect the front display panel flat ribbon cable from the main PCB. The replacement main PCB can now be installed by connecting the front display panel ribbon cable, sliding the PCB into the instrument case, seating it into the rear terminal board slot, and installing the front display panel.

 NOTE: Power Supply Fuses

AC Power: 1A, 250 V, Fast Blow Schurter Type 034.3930

DC Power: 3A, 250 V, Slow Blow BEL Type 5TT3

For additional information, contact MicroMod Automation.

53IT5100B Indicator/Totalizer

INSTRUCTION MANUAL

NOTE: When communicating with MicroMod for replacement of the main PCB, reference the unit’s serial number to ensure the correct replacement assembly is supplied. The necessary ordering information is provided on the instrument data tag and on the manufacturing specification sheet supplied with that particular controller.

In the event of a hardware malfunction, a replacement PCB can be quickly substituted for the defective assembly to minimize downtime. Contact MicroMod for instructions before returning equipment.

The defective PCB should be carefully packaged and returned, shipping charges prepaid, to the Repair Dept. of MicroMod Automation. Do not wrap PCBs in plastic, as it can cause static damage. It is suggested that the defective PCB be returned in the special bag in which the replacement module was supplied.

5.3 Calibration

The instrument’s analog inputs (ANI0-3) and output (ANO0) are extremely stable. They normally do not require recalibration. If it becomes necessary to recalibrate the instrument, due to the inadvertent change of the stored calibration values, then this can be accomplished by altering their respective datapoints. The calibration span and zero datapoint locations are as follows:

ANI0 ANI1 ANI2 ANI3 ANO0

Calibrate Zero B263 B264 B265 B266 B267

Calibrate Span C296 C297 C298 C299 C300

5.4 Error and Hardware Malfunction Messages

Entire Display Flashes - The watchdog timer has timed out.

CPU RAM FAILURE - IC U1 is bad.

ROM CHKS FAILURE - IC U3 is bad.

5.5 Resetting the Instrument

The instrument can be reset either by cycling the power, or by carefully pressing the reset button by inserting a thin wire, such as a paper clip, through the small hole in the upper left corner of the front bezel. (See Figure

1-2 for the location of the reset hole.) When the instrument restarts, it immediately checks to determine if any of the horizontal keypad push buttons are held pressed.

 If 1 push button is held pressed during instrument reset, the instrument enters a factory test

mode. The test mode can be exited by resetting the instrument again using the thin wire with no push buttons pressed.

 If 2 push button is held pressed during instrument reset, the instrument database is set to the

defaulted values.

Appendix A: Discrete Contact Output CCO’s

The discrete output CCOs are not mechanical contact closures but NPN Transistors that are analogous to single pole, single throw switches with one terminal connected to power common. This circuit type layout is commonly called an Open Collector Output. (See Figure A-1.)

Capability limits of each CCO are as follows:

 50 mA maximum current flow when closed.

 30 V dc maximum tolerance voltage when open.

A CCO will operate any external device that can be made to switch if it does not require more than 50 mA of current to the (+) terminal.

Typical uses for a CCO are to actuate a small relay, activate an external alarm buzzer, provide

Contact Input (CCI) to another instrument, or provide output to an annunciator panel.

A CCO circuit is equivalent to an unpowered switch. If the 24 V dc supply of the instrument is not already fully loaded (see note), it can be used as a source of power for a CCO; otherwise, a separate, external dc supply must be used. In the upper circuit illustration of Figure A-2, the +24 V is obtained from screw lugs 1 or 4 of

TB1 located on the instrument rear terminal board. (See Figure 2-4.)

NOTE: Power source - 80 mA maximum.

In Figure A-1, the switch is closed when the output logic bit (L24 for CCO0, L25 for CCO1) is set to 1, provided that its respective invert bit (L288 for CCO0, L289 for CCO1) is 0. The relay in Figure A-2 is energized when the output bit is set to 1 if the invert bit is 0. If the invert bit is set to 1, the output bit will cause the relay to de-energize when it is set to 1.

Figure A-2 also shows how a dc electromechanical relay is operated using an internal or external power source. There are many dc relays available with a coil resistance of 430 ohms or more. (Note: with the 24 V dc supply, a 430 ohm coil resistance will pass 50 mA of current.) Figure A-3 shows how several CCOs can be arranged in parallel using one power source so that any one CCO can actuate a single relay.

Figure A-4 shows a CCO used to control a solid state relay (see note). The resistor is added to the circuit from the power source to limit the current flow, and also to establish the voltage across the relay when the

CCO switch is open.

NOTE: Several manufacturers are Crydom Division, International Rectifier and OPTO 22.

In Figure A-5, the CCO of one instrument is applied directly to the CCI of another instrument.

When the CCO closes, the CCI circuit of the second instrument is complete. An appropriate resistance is required in the second instrument, as it provides the power for its CCI operation.

Appendix B : Communications

Two digital communication channels are provided with this instrument:

 RS-232 serial configuration port, accessed via a 5 pin mini-DIN connector located under the pulldown door on the front panel (see Figure 1-2). It is used to configure instrument parameters for selected operational characteristics. The parameters are configured with Micro-Tools software running on a customer supplied PC.

 RS-422/485 serial interface used to connect the instrument to a Datalink multi-drop network. Interface connection to the Datalink network is via the rear terminal board (TB1) of the instrument, pins 19 through 22, as shown in Section 2.

Information in this section applies to both the configuration port and the Datalink interface

The configuration port data rate is 9600 baud, with 8 data bits, and no parity.

The Datalink interface requires four conductors: a transmit pair and a receive pair. The voltage levels of each conductor pair conform to the EIA RS-422/485 standard. In accordance with this standard, the overall

Datalink network distance is limited to 4000 feet when #24 AWG twisted pair wire is used to interconnect the nodes. Adapters are available to convert RS-422/485 to RS-232 or 20 mA current loops.

In a Datalink network, the instruments communicate as Responders to host queries. The host or PC functions as the Interrogator and acts as the central control point for the Datalink network. A maximum of 32 addressable instruments can be connected to a Datalink network.

Calculating Data Addresses

If communications software must be generated to accommodate unique Datalink applications requirements, then the instrument memory address scheme must be known for proper data bit (e.g., L data type) and data byte (e.g., B, C, H, and A data types) memory location determination.

NOTE: Numbers used in this section that are expressed in hexadecimal notation (base 16) are identified with an H after the number.

This memory address scheme applies only if a 6 is in memory address location 8002H. Memoryaddress location 8002H must be read and if it contains a 6, then the address scheme that is described in Table B-3 should be applied for this instrument.

Data Format

1 Represents a positive integer with values from 0 to 255.

Address Calculation Algorithm

Address = B Base + (B Number)

= 200H + (B Number)

Address example: B012 location =

200H + 12D = 200H + CH = 20CH

L 500H

C 600H

1 Bit A single binary bit with a logical value of 0 or 1. L datapoints are packed 8 to a byte.

3 Represents floating point values that have a resolution of one part in

32,768 (15 bits) and a dynamic range of ± 1038 . The first two bytes represent a 2’s complement notation in fractional form (2-n ) whose absolute value is between 0.5 and

0.9999. The third byte is the power of 2 in 2’s complement notation.

Floating point example: 64H 00H

07H = 100D (Decimal) 64H = 0110

0100, fractional binary weights left to right are 0 = 2’s complement positive, 1 = 2-1 = 1/2 = 0.5, 1 = 2-2

= 1/4 = 0.25, 0=0, 0=0, 1 = 2-5 =

1/32 = 0.03125, 0=0, and 0=0. 64H =

0.5+0.25+0.03125 = 0.78125.07H =

128D. 128D X 0.78125D = 100.

Address = L Base + (L Number/8)

= 500H + (L Number/8)

Remainder = bit position in byte

Address example: L014 location =

500H + 14/8 = 501H, bit 6 (remainder).

Address = C Base + (3 X C Number)

= 600H + (3 X C Number)

Address example: C011 location

600H + (3 X 11) = 600H + 33D

= 600H + 21H = 621H.

5 Represents high precision floating point values that have a resolution of one part in 2 billion (31 bits) and a dynamic range of ± 1038 . The first four bytes represent a 2’s complement notation in fractional form (2-n) whose absolute value is between 0.5 and 0.9999. The fifth byte is the power of 2 in 2’s complement notation. Floating point example: 9CH 00H 00H 00H 07H =

-100. The 2’s complement notation

10 (A)

5 (F)* bit in the 9 = 1 (1001) indicating a negative number; therefore, 9C must be re-complemented . 9C =

1001 1100, change 1’s to 0’s and

0’s to 1’s = 0110 0011 and add 1=

0110 0100 (64H). Fractional binary weights left to right for 0110 0100 are 0 = 2’s complement positive, 1

= 2-1 = 1/2 = 0.5, 1 = 2-2 = 1/4 =

0.25, 0=0, 0=0, 1= 2-5= 1/32 =

0.03125, 0=0, 0=0. 64H = 0.5 +

0.25 + 0.03125 = 0.78125.

07H=128D, 128D X 0.78125D =

100. A negative sign is assigned (-

100) because the original 2’s complement binary bit in the 9

(1001) of 9C was set indicating a negative number.

The A data format represents text strings that are 10 characters long.

The F data format represents text strings that are 5 characters long.

Address Calculation Algorithm

Address = H Base + (5 X H Number) =

F00H + (5 X H Number)

Address example: H001 location F00H

+ (5 X 1) = F00H + 5D = F00H + 5H =

F05H.

Address = A Base + (10 X Number)

= 1400H + (10 X Number)

(for both A and F data types)

Address example: A015 location

1400H + (10 X 15) = 1400H + 150D =

1400H + 96H

1496H.
