GENERAL DESCRIPTION

The Model C48 Timer is available in Single or Dual Preset models. The

C48T features a 7 segment, 2 line by 6 digit reflective or backlit LCD display.

For the backlit versions, the main display line is red and shows the timer value.

The smaller secondary display line is green and can be used to view the preset

values or output time values.

The C48 Timer can be configured for a variety of different operating modes

to meet most timing application requirements. Twelve timing ranges are

available from thousandths of a second to hours and minutes. Decimal Points

are used to separate the time units (hours, minutes, seconds). Timing can be

cumulative or can reset and start upon each power cycle. “On Delay” or “Off

Delay”, “Single Shot”, and “Repetitive auto cycling” modes are all supported.

Four front panel push-buttons are used for programming the operating modes

and data values, changing the viewed display, and performing user

programmable functions, e.g. reset, etc. The C48T can be configured for one of

two numeric data entry methods, digit entry or automatic scrolling. The digit

entry method allows for the selection and incrementing of digits individually.

The automatic scrolling method allows for the progressive change of one

through all digit positions by pressing and holding the “up” or “down” button.

The C48 Timer has a Run/Stop Input, 3 programmable User Inputs, and a

programmable front panel function key. The Run/Stop and User Inputs can be

configured as sinking (active low) or sourcing (active high) inputs via a single

plug jumper. The following functions are available for user inputs and the front

panel function key:

The Dual Preset models are available with solid-state or Relay outputs. The

Single Preset model has a solid-state and relay output in parallel. All solid-state

outputs are available in a choice of NPN current sinking or PNP current

sourcing, open-collector transistor outputs.

The Timer can also be configured to Continue or Stop timing upon reaching

Preset. The display can be programmed to stop at the preset value (Reset to Zero

mode) or zero (Reset to Preset mode), or automatically reset to zero or preset

and hold. Once stopped, the timer can be restarted by manually resetting it, or

it can be programmed to restart when power is reapplied.

Optional RS485 serial communication capabilities allow for interrogation

and modification of the preset and timer values.

Optional programming software (SFC48) is available to program all unit

configuration parameters. The software allows unit configurations to be created,

uploaded, downloaded, and saved to a file for later use or multi-unit

programming.

The unit is constructed of a lightweight, high impact plastic case with a

textured front panel and a clear display window. When properly installed, the

front panel meets NEMA 4X/IP65 specifications for indoor use. Multiple units

can be stacked horizontally or vertically. Modern surface-mount technology,

extensive testing, plus high immunity to noise interference makes the C48

Timers extremely reliable in industrial environments.

Safety Summary

All safety related regulations, local codes and instructions that appear in the

manual or on equipment must be observed to ensure personal safety and to

prevent damage to either the instrument or equipment connected to it. If

equipment is used in a manner not specified by the manufacturer, the protection

provided by the equipment may be impaired.

Do not use this unit to directly command motors, valves, or other actuators

not equipped with safeguards. To do so, can be potentially harmful to persons

or equipment in the event of a fault to the unit.

INSTALLATION & CONNECTIONS

The C48 Timer meets NEMA 4X/IP65 requirements for indoor use to

provide a watertight seal in steel panels with a minimum thickness of 0.09

inch, or aluminum panels with a minimum thickness of 0.12 inch. The

units are intended to be installed into an enclosed panel. The complete

unit assembly (i.e. PC boards and bezel), MUST be in the case when

mounting the unit.

Multiple Unit Stacking

The C48T is designed for close spacing of multiple units. Units can be

stacked either horizontally or vertically. For vertical stacking, install the

panel latch with the screws to the sides of the unit. For horizontal

stacking, the panel latch screws should be at the top and bottom of the

unit. The minimum spacing from center line to center line of units is 1.96”

(49.8 mm). This spacing is the same for vertical or horizontal stacking.

Note: When stacking units, provide adequate panel ventilation to ensure

that the maximum operating temperature range is not exceeded.

Mounting Instructions

1. Prepare the panel cutout to the dimensions shown in Figure 3, Multiple Unit

Stacking.

2. Remove the panel latch from the unit. Discard the cardboard sleeve.

3. Carefully remove the center section of the panel gasket and discard. Slide the

panel gasket over the unit from the rear, seating it against the lip at the front

of the case.

4. Insert the unit into the panel cutout. While holding the unit in place, push the

panel latch over the rear of the unit, engaging the tabs of the panel latch in

the farthest forward slot possible.

5. To achieve a proper seal, tighten the panel latch screws evenly until the unit

is snug in the panel, torquing the screws to approximately 7 in-lbs.

Overtightening can result in distortion of the panel, and reduce the

effectiveness of the seal.

Note: The installation location of the timer is important. Be sure to keep it away

from heat sources (ovens, furnaces, etc.), and away from direct contact with

caustic vapors, oils, steam, or any other process by-products in which

exposure may affect proper operation.

Caution: Disconnect power to the unit and to the output control circuits

to eliminate the potential shock hazard when removing the entire unit

or unit assembly.

Unit Removal Procedure

To remove the entire unit (with case) from the panel, first loosen the panel

latch screws. Insert flat blade screwdrivers between the panel latch and the case

on either side of the unit, so that the latches disengage from the grooves in the

case. Push the unit through the panel from the rear.

Removing Unit Assembly

The unit assembly, shown in Figure 4, must be removed from the case to

change plug jumper settings or to replace the relay output board. To remove the

unit assembly, insert a flat blade screwdriver into the pry slot on either side of

the unit. Twist the screwdriver handle until the unit is ejected enough to allow

removal.

Caution: The unit assembly contains electronic circuits that can be damaged by

static electricity. Before removing the assembly, discharge static charge on

your body by touching an earth ground point. It is also important that the unit

assembly be handled only by the bezel. Additionally, if it is necessary to

handle a circuit board, be certain that hands are free from dirt, oil, etc., to

avoid circuit contamination that may lead to malfunction. If it becomes

necessary to ship the unit for repairs, place the unit in its case before

shipping it.

Installing Unit Assembly

To install the unit assembly, insert the assembly into the case until the bezel

is fully seated against the lip of the case. Properly installing the unit assembly

is necessary for watertight sealing.

C48t-im.QXD 3/5/04 3:28 PM Page 4

Output Board

The C48T is supplied with an output board installed. The output board is

preconfigured for the type of output needed, based upon the Model ordered. See

Ordering Information, page 35, for available models. All relay output boards are

field replaceable.

Replacing Relay Output Board

1. Remove the unit assembly. (See Removing Unit Assembly, page 4).

2. Lift up on the top bezel board latch while gently pulling out on the

bezel/display board assembly. Do NOT remove the display board from the

bezel.

3. Remove the output board by pulling it away from the other boards. Replace

the output board by aligning the board to board connectors. Be certain

connectors are fully mated.

4. Connect the bezel/display board assembly by guiding the board ends into the

bezel latches. Slide the assembly on evenly until the display board connector

is completely engaged and bezel latches are

fully seated onto the boards.

Note: When replacing the

relay output board, be

certain to install a new

output board of the

same type.

EMC INSTALLATION GUIDELINES

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

ElectroMagnetic 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. The unit becomes more immune to EMI with fewer I/O

connections. Cable length, routing and shield termination are very important

and can mean the difference between a successful installation or a troublesome

installation. Listed below are some EMC guidelines for successful installation

in an industrial environment.

1. The unit should be mounted in a metal enclosure, that is properly connected

to protective earth.

2. 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 panel 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.

3. 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.

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

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

components.

5. 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 #1VR3

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

6. Long cable runs are more susceptible to EMI pickup than short cable runs.

Therefore, keep cable runs as short as possible.

7. Switching of inductive loads produces high EMI. Use of snubbers across

inductive loads suppresses EMI.

Snubbers:

RLC #SNUB0000

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. It is recommended that power supplied to the unit (AC

or DC) be protected by a fuse or circuit breaker.

After the unit has been mechanically mounted, it is ready to be wired. All

wiring connections are made to rear screw terminals. When wiring the unit, use

the numbers on the label and those embossed on the back of the case, to identify

the position number with the proper function (See page 35, for terminal

descriptions). Strip the wire, leaving approximately 1/4″(6 mm) bare wire

exposed (stranded wires should be tinned with solder). Insert the wire under the

clamping washer and tighten the screw until the wire is clamped tightly.

Caution: Unused terminals are NOT to be used as tie points. Damage to the

timer may result if these terminals are used.

C48t-im.QXD 3/5/04 3:28 PM Page 6

POWER WIRING

AC Versions (C48TXX0X)

AC Power Wiring

Primary AC power is connected to terminals 11 and 12, labeled AC. To

reduce the chance of noise spikes entering the AC line and affecting the timer,

an AC feed separate from that of the load should be used to power the timer. Be

certain that the AC power to the timer is relatively “clean” and within the

specified range. Connecting power from heavily loaded circuits or circuits that

also power loads that cycle on and off, (contacts, relays, motors, etc.) should be

avoided.

DC Power Wiring (Non PNP Output models)

The DC power is connected to terminals 9 & 10, marked COMM. and DC

OUT/IN. The DC power source must be capable of supplying the unit’s rated

current (150 mA max.) and be within the specified 11 to 14 VDC range. The

C48T has non-volatile memory, that stores information on power down, thereby

eliminating the need for battery back-up.

Note: AC versions with PNP outputs cannot be powered from DC.

Caution: Observe proper polarity when connecting DC voltages.

Damage to the unit will occur if polarity is reversed.

DC Versions (C48TXX1X)

DC power (18 to 36 VDC) or low voltage AC power (24 VAC) is connected

to terminals 11 and 12, labeled DC+ (AC) and DC- (AC) respectively.

Output Power

For DC/ Low Voltage units that do not have PNP current sourcing outputs,

Terminal 10, DC OUT (VSRC IN), provides a DC output for sensor power (+12

VDC +/-15%). The maximum sensor current is 100 mA.

For units with PNP current sourcing outputs, this terminal serves a dual

purpose depending on the application’s PNP output voltage level and current

requirements.

1. The terminal may be used as a +12 VDC output for sensor power. In this

case, the PNP output voltage level will be +12 VDC (±15%). A maximum

of 100 mA is available for the combination of sensor current and PNP

output sourcing current.

2. If a higher PNP output voltage level or additional output sourcing current

is desired, an external DC supply may be connected between the “DC

OUT (VSRC IN)” and “COMM.” terminals. This supply will determine the

PNP output voltage level, and must be in the range of +13 to +30 VDC.

An external DC supply can also provide the additional output sourcing

current required in applications where two or more PNP outputs are

“ON” simultaneously. However, the maximum current rating of 100

mA per individual output must not be exceeded, regardless of external

supply capacity.

Serial Communications Wiring

It is recommended that shielded (screened) cable be used for serial

communications. This unit meets the EMC specifications using Alpha #2404

cable or equivalent. There are higher grades of shielded cable, such as, four

conductor twisted pair, that offer an even higher degree of noise immunity.

Refer to RS-485 Serial Communications, page 24, for wiring and operational

procedures.

Run/Stop Input

The RUN/STOP input can be configured as a current sinking (active low) or

current sourcing (active high) input using the User Input plug jumper. The timer

will RUN when RUN/STOP (terminal #7) is connected to the active logic level.

See chart on Page 8, for active and inactive voltage levels for each User Input

plug jumper setting.

In some operating modes, the timer will automatically STOP timing when the

main output is triggered. (See Timer Operating Modes in the programming

section, Page 13.) In these modes, the RUN/STOP input can be used to restart

the timer by momentarily taking the input to the STOP state (inactive logic

level) and then back to the RUN state (active logic level). Cycling the

RUN/STOP terminal, however, will not reset or affect the output(s).

-7-

C48t-im.QXD 3/5/04 3:28 PM Page 7

-8-

User Inputs

The three external user inputs are programmable inputs that can be

configured as current sinking (active low) or current sourcing (active high)

inputs via a single plug jumper. Programmable external user inputs are digital

inputs. The use of shielded cable is recommended. Follow the EMC Installation

Guidelines for shield connection. See User Inputs, page 19, for a description of

all available user input functions. The active logic state of ALL user inputs is

dictated by the position of the User Input plug jumper. The plug jumper is

located on the CPU board (See Figure 9, User Input and Program Disable

Jumper Locations).

OUTPUT WIRING

Relay Connections

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 electro-mechanical devices to be

held ON.

Program Disable Plug Jumper

The program disable plug jumper is used to enable and disable front panel

programming of the C48T. See Front Panel Accessible Functions With Program

Disable, page 11, for a description of available functions. The plug jumper is

located on the CPU board (See Figure 9, User Input and Program Disable

Jumper Locations).

Programming of the C48T is done through the front panel keypad. English

language prompts, flashing parameter values, and the front panel keypad aid the

operator during programming.

Although the unit has been programmed at the factory, the parameters

generally have to be changed to suit the desired application. In order to access

the Programming Menu, the Program Disable jumper and/or any User Input

programmed for Pro.dIS may need to be turned off or deactivated. When

shipped from the factory, all programming is enabled. See Front Panel

Accessible Functions With Program Disable, page 11, for program disabling

options. With programming enabled, to enter the programming menu, the A

key is pressed and held for two seconds. Once in the programming menu, the

Akey is used to sequence through the list of programming parameters. To loop

backwards one item in the Programming Menu, press and hold the Akey, then

quickly press and hold the Ckey while releasing the Akey. Repeatedly

pressing the Akey with the Ckey held will continue the backwards

sequencing.

Programming Option Values

The operator can scroll through the available options for a selected parameter

by pressing the Bor Ckey to enter parameter change mode, and then pressing

the Bkey repeatedly until the desired option is viewed. The option is entered

by pressing the Akey, which returns the operator to the Programming Menu.

Programming Numeric Data Values

The Presets and output time values may be accessible when the unit is in the

normal operating mode (not programming mode), providing that the Program

Disable input is not activated. Pressing the Akey will sequence the secondary

display through the available presets and output time values.

To change a numeric data value, it must be visible on the secondary display.

Pressing the Bor Ckey will allow changing of the value. The two methods

for changing numeric data values are “digit entry” and “auto scrolling”.

Digit Entry

If the preset entry method has been set to “digit entry”, the least significant

digit will blink. Pressing the Ckey multiple times will select other digits.

Pressing the Bkey will increment the selected digit. The data value will be

entered when the Akey is pushed, or the old value will be retained if no key

activity is detected for 10 seconds.

Short-Cut - Decrementing Value

To decrement a digit value, press and hold the Bkey and then press the C

key. This will decrement the selected digit to zero if held.

Auto Scrolling

If the data entry method is set to “auto scrolling”, the data value can be

progressively changed by pressing and holding the Bor Ckeys. If one of the

keys is pushed and held, the value will scroll automatically. After 5 counts, the

unit enters fast scroll mode. If a key remains pushed, a digit shift occurs every

one hundred counts until the maximum value or zero is reached. When the digit

shift occurs, the previously scrolling digit goes to zero. When scrolling at the

higher order digit locations, you can switch directions by quickly pressing the

other key (Bor C) within a second following the release of previous direction

key.

Short-Cut - Quick Digit Shift

To quickly select higher order digits while incrementing or decrementing

numeric values (with Bor Cheld), press and hold the Akey. This sequences

the selected digit from the least to the most significant digit. As each digit is

passed, it changes to zero. When the desired digit is reached, release the Akey

to increment or decrement from the new digit location.

Saving Program

All parameter values changed in programming mode are saved when exiting.

To exit programming mode, press and hold the Akey for two seconds. The

display will momentarily display Pro9 SAVE while the parameter values are

saved in non-volatile memory. The unit then returns to the indication display

that was last viewed.

PROGRAMMING GENERAL DESCRIPTION

C48t-im.QXD 3/5/04 3:28 PM Page 12

The operating modes of the C48T are programmed using the front panel

keypad. (See page 12, for details on using the keypad to program the unit)

Accessibility to the Programming Menu depends on the Program Disable

Function setting (See page 11, for available program disable settings).

Numeric Value Entry Method

Configures push button response for entering numeric

data values such as Presets and Output Times

Timer Range

The timer range determines the time units to be used.

Timer Operating Mode

The charts on the following pages, show operating

modes for the Single Preset and Dual Preset Timer Models.

In the descriptions below, the “Main Preset” or “Output”

refers to “Preset 1” or “Output 1” on the Single Preset

Model. On the Dual Preset Model it refers to “Preset 2” or

“Output 2”.

Reset Type:

Auto - Unit automatically resets as programmed, when timer triggers main

preset’s output or at it’s timed output end.

Manual - Unit does not reset when timer triggers main preset’s output or at

it’s timed output end. The timer value can be manually reset by a User

Input or by Serial Communications command.

Reset to:

Zero - When reset (manually or automatically) timer value goes to zero. The

Main Preset Output is triggered when timer value reaches main Preset

Value.

Preset - When reset (manually or automatically), the main Preset value is

loaded into the timer value. The main Preset Output is triggered when

timer value reaches zero.

At Timed Output End:

When this mode is selected, Auto Reset occurs when the main preset’s

Output time elapses and the main output deactivates. If not selected, Auto

reset occurs when the main output is triggered.

Continue Timing at Main Output:

The timer continues timing when main output is triggered. To stop timing,

the “Run/Stop” terminal is put into the “Stop” state. This mode is useful for

repetitive, auto-cycling applications.

Stop Timing at Main Output:

The timer will stop when the main preset’s output is triggered. To resume

timing, a manual reset (User Input - rSt-E) is performed, which resets the

output and the stop condition. The Run/Stop input can also be used to restart

the timer by putting it in the “Stop” state and then back to the “Run” state.

Cycling the Run/Stop however, will not reset or affect any outputs. This

mode is used to provide “one-shot” capability.

RS-485 SERIAL COMMUNICATIONS

RS-485 communications allows for transmitting and receiving of data over a

single pair of wires. This feature can be used for monitoring various values,

changing values, and resetting output(s), all from a remote location. Typical

devices that are connected to a C48T unit are a printer, a terminal, or a host

computer.

The RS-485 differential (balanced) design has good noise immunity and

allows for communication distances of up to 4000 feet. Up to 32 units can be

connected on a pair of wires and a common. The unit’s address can be

programmed from 00 to 99.

Communication Format

The half-duplex communication operation sends data by switching voltage

levels on the common pair of wires. Data is received by monitoring the levels

and interpreting the codes that were transmitted. After the unit receives a

Transmit Command or Print Request, it will wait 100 msec before it will begin

transmitting data. In order for data to be interpreted correctly, there must be

identical formats and baud rates between the communicating devices. The

formats available for the C48T unit are 1 start bit, 7 or 8 data bits, No parity or

1 parity bit (odd or even) and 1 stop bit. The available baud rates are 1200, 2400,

4800, or 9600 baud.

Before serial communication can take place, the unit must be programmed to

the same baud rate and parity as the connected equipment. In addition, the loop

address number and print options should be known. When used with a terminal

or host computer and only one unit is employed, an address of zero (00) may be

used to eliminate the requirement for the address specifier when sending a

command. If more than one unit is on the line, assignment of unique non-zero

addresses is recommended.

Sending Commands And Data

When sending commands to the C48T unit, a command string must be

constructed. The command string may consist of command codes, value

identifiers, and numerical data. Below is a list of commands and value

identifiers that are used when communicating with the C48T unit.

-24-

P (50H)

S (53H) Set value; Followed by one value identifier (1 or 2)

T (54H) Transmit value; Followed by one value identifier (A, B, or E)

V (56H)

Transmit Print Options; Transmits the options selected in the Print

Options section of the Programming Menu

C48t-im.QXD 3/5/04 3:29 PM Page 24

Note: Command identifiers other than those listed should NOT be transmitted.

Otherwise, undefined or unpredictable operation could result.

The command string is constructed by using a command, a value identifier,

a data value if required, and the command terminator(*). The Data value need

not contain the decimal point(s) since they are fixed within the C48T, based on

the timer range programmed at the front panel. The unit will accept the decimal

point(s), however, it does not interpret them in any way. Leading zeros can be

eliminated, but all trailing zeros must be present.

Example: If a Preset of 1.000 is to be sent, the data value can be transmitted as

1.000 or 1000. If a “1” is transmitted, the Preset will be changed to 0.001.

The Address command is used to allow a command to be directed to a

specific unit on the Serial Communications Line. When the unit address is zero,

transmission of the Address command is not required. This is done for

applications that do not require more than one unit. For applications that require

several units, it is recommended that each unit on the line be given a specific

non-zero address. If they are given the same address, a command such as the

Transmit Value Command, will cause all of the units to respond simultaneously,

resulting in a communication collision. All units in a multiple unit application

should be given an address other than zero. If a unit has an address of zero, it

will attempt to process any transmissions from the other units as commands.

These transmissions fill up the receive buffer of the unit with an address of zero,

which may produce unpredictable results.

In a multiple unit configuration, an asterisk (2AH) must be sent to clear the

input buffer of all units on the line after a transmit value or print request

command is sent to a specific unit on the line. The C48T will require a

maximum of 50 msec to process the asterisk (*).

The command string is constructed in a specific logical sequence. The C48T

will not accept command strings that do not follow this sequence. Only one

operation can be performed per command string. Below is the procedure to be

used when constructing a command string.

1. The first two to three characters of the command string must consist of the

Address Command (N) and the address number of the unit (1 thru 99). If the

C48T address is zero, the address command and number need NOT be sent.

2. The next character in the command string is the actual command that the unit

is to perform (P, R, S, T, or V).

3. A Value Identifier is next if it pertains to the command. The command P

(print) does not require a Value Identifier.

4. The numerical data will be next in the command string if the Change Value

command (V) is used.

5. All command strings must be terminated with an asterisk * (2AH). This

character indicates to the C48T that the command string is complete.

Below are some typical examples of properly constructed command strings.

Examples:

1. Change Preset 1 Value to 123.4 on the C48T with an address of 2.

COMMAND STRING: N2VA1234*

2. Transmit the Timer Value of the C48T unit with an address of 3.

COMMAND STRING: N3TE*

3. Reset Output 1 of the C48T unit with an address of 0.

COMMAND STRING: R1*

If illegal commands or characters are sent to the C48T, the unit will respond

by transmitting an error character “E” (45H), in which case the string must be

re-transmitted.

When writing application programs in Basic, the transmission of spaces or

carriage return and line feed should be inhibited by using the semicolon

delimiter with the “PRINT” statement. The C48T will not accept a carriage

return or line feed as valid characters. See Terminal Emulation Program, page

27, for a listing of an IBM®PC Basic terminal emulation program.

C48t-im.QXD 3/5/04 3:29 PM Page 25

It is recommended that a “Transmit Value” command follow a “Change

Value” Command. If this is done, the reception of the data can provide a timing

reference for sending another command and will ensure that the change has

occurred. When a “Change Value or Reset Value” command is sent to the C48T,

there is time required for the unit to process the command string. The diagrams

show the timing considerations that need to be made.

Receiving Data

Data is transmitted from the C48T when a “T” Transmit Value or a “P”

Transmit Print Options command is sent to the unit via the serial port or when

a User Input, programmed for the Print Request function, is activated. The

C48T will wait a minimum of 100 msec and then begin transmissions. The

C48T can also be programmed to transmit mnemonics. The format for a typical

transmission string with mnemonics is shown below:

The first two digits transmitted are the unit address followed by one blank

space. The next three characters are the mnemonics followed by three or more

blank spaces. The numerical data value is transmitted next. The decimal point

position will “float” within the data field depending on the actual value it

represents. The numeric data is right justified without leading zeros.

When a “T” command or print request is issued, the above character string is

sent for each line of a block transmission. An extra <SP><CR><LF> is

transmitted following the last line of transmission from a print request, to

provide separation between print outs.

If serial is abbreviated (SErAbr = YES), just numeric data is sent with no time

delay. If the C48T transmits mnemonics, there is a 400 msec built-in time delay

after each transmission string. When interfacing to a printer, sending

mnemonics is usually desirable. Examples of transmissions are shown below:

3 P2 6732.5<CR><LF> Mnemonics Sent

6732.5<CR><LF> NO Mnemonics Sent

The various Print Options are used with a printer or a Computer Terminal.

They provide a choice of which C48T data values are to be printed, when either

the User Input, programmed for the print request function is activated, or a “P”

(Transmit Print Options) command is sent to the C48T via the serial port. See

Print Options, page 21, for the available options.

Print outs from a C48T unit with an address of 1 and the following print

options are shown below:

Terminal Emulation Program For IBM® PC

Utilizing the Serial communications capability of the C48T will require the

use of an RS485 serial card in the computer. If an IBM®PC compatible is being

used, this card would be installed in an expansion slot on the mother-board. The

RS485 card should be configured for “2-wire half-duplex” operation. For this

mode of operation, each piece of equipment must be able to switch from receive

mode to transmit mode and vice-versa. The C48T is normally in the receive

mode. It will automatically switch to the transmit mode when a Transmit Value

Command is issued or a Print Request is issued. For the computer to switch

from receive to transmit mode, the controlling software must be written to

perform this task. On most RS485 serial cards, the RTS (Request-to-send)

signal can be configured to be used as the direction (transmit/receive) control

signal. The controlling software must switch the state of the RTS line when the

computer is to switch from transmitting to receiving data.

Listed below is a basic program that will emulate a terminal. It is written

using IBM®PC Basic. The program may need to be modified if using a

different basic interpreter. Set up the C48T for a baud rate of 9600. When the

program is running, commands can be typed in from the keyboard as shown in

the previous examples above. An asterisk (*) is used to end all commands. Do

NOT use the carriage return to end a command.

Serial Connections

When wiring, refer to the numbers listed on the label with the terminal

description for installing each wire in its proper location.

For RS-485, the data (transceiver) wires connect to the A(+) and B(-)

terminals. It is recommended that shielded (screened) cable be used for serial

communications. In some applications, a signal ground may be required to

establish a ground reference. The signal ground is required if the equipment

does not have internal bias resistors connected to the transceiver lines. If

necessary, the shield can be used as the signal ground.

CONNECTING TO A HOST TERMINAL

Six C48T units are used to monitor and control parts

packaging machines in a plant. C48T units are located at

Troubleshooting Serial Communications

If problems are encountered when interfacing the C48T(s) and host device or

printer, the following check list can be used to help find a solution.

1. Check all wiring. Refer to the previous application and use it as a guide to

check your serial communication wiring. Proper polarity of all C48T(s) and

other peripherals must be observed.

2. If the C48T is connected to a “host computer”, device or printer, check to

make sure that the computer or device is configured with the same

communication format as the C48T. The communication format the C48T

will accept is; 1 start bit, 7 or 8 data bits, no parity or 1 parity bit (odd or

even), and 1 stop bit.

3. Check the baud rate and parity in the Programming Menu SErSEt parameter,

and make sure all devices on the line are set to the same baud rate and parity.

4. Check the C48T’s unit address. If the Address command is not used when

transmitting a command to the C48T, the C48T’s address must be set to 0.

See Sending Commands & Data, page 24, for command structure.

5. If two-way communications are to be established between the C48T and a

computer, have the computer receive transmissions from the C48T first.

Activating a User Input, programmed for the print request function, will

initiate transmissions from the C48T.

6. When sending commands to the C48T, an asterisk * (2AH) must terminate

the command.

7. In multiple unit configurations, make sure each unit has a different address

other than zero. If a transmit value or print request command is issued, an

asterisk (*) must be sent before sending another transmission.

8. If all of the above has been done, try reversing the polarity of the transceiver

wires between the C48T (s) and the RS485 interface card. Some cards have

the polarity reversed.

One Shot Timing Cycle

Proper wash down mixture for a food processing plant is an important factor

in maintaining the clean environment required. A disinfectant solution is added

to the mixing/holding tank used for the wash down cycle. When the holding

tank is near empty, a level transducer activates the filler pump. A C48TS is used

to turn on the disinfectant solution pump for a preprogrammed amount of time

during the filling process of the holding tank.

When the filler pump starts, a momentary contact closure activates User

Input 1, resetting the C48 Timer. The timer begins the timing cycle since the run

terminal is connected to common. The normally open relay contacts close at the

timer reset signal activating the disinfectant solution pump. When the

programmed preset is reached, timing stops and the relay deactivates, turning

off the pump controlling the disinfectant solution. The C48 Timer’s preset cycle

time may be changed according to the manufacturer’s concentration level of the

disinfectant.
