Precautions for Safe Use

Precautions for the environment.

(1) Do not use the product in the following locations.

• Locations subject to direct radiant heat from heating equipment

• Locations here the product may come into contact with water or oil

• Locations subject to direct sunlight

• Locations where dust or corrosive gases (in particular, sulfuric or ammonia gas) are present

• Locations subject to extreme temperature changes

• Locations where icing or condensation may occur

• Locations subject to excessive shocks or vibration

(2) Do not use the product in locations subject to temperatures or humidity levels outside the specified ranges or in locations prone to condensation. If the product is installed in a panel, ensure that the temperature around the product (not the temperature around the panel) does not go outside the specified range. Parts life is dependent on temperatures. A part life shortens when the temperature rises, and it lengthens when the temperature falls.

Parts life can be lengthened by lowering the temperature inside the product.

(3) In order to prevent inductive noise, wire the lines connected to the product separately from power lines carrying high voltages or currents. Do not wire in parallel with or in the same cable as power lines. Other measures for reducing noise include running lines along separate ducts and using shield lines.

(4) Do not install the product near devices generating strong high-frequency waves or surges.

When using a noise filter, check the voltage and current and install it as close to the product as possible. If several products are mounted side-by-side or arranged in a vertical line, the heat dissipation will cause the internal temperature of the product to rise, shortening the service life. If necessary, cool the products using a fan or other cooling method.

(5) Take care when cleaning the product, because the exterior of the product contains organic solvent (thinner, benzine, etc.), strong alkaline material and strong acid material.

(6) Avoid storing in high humidity or in a corrosive gas environment (including during transportation)

Precautions for Safe Use.

(1) Use and store within the proper temperature and humidity described in the specifications.

(2) Provide sufficient space around the product for heat dissipation.

(3) When using the product stored unused over a year after purchasing, the product features may not be utilized sufficiently.

(4) Avoid storing outdoors and in a place that receives direct sunlight (including during transportation).

(5) The service life of the output relays depends on the switching capacity and switching conditions. Consider the actual application conditions and use the product within the rated load and electrical service life. Using the product beyond its service life may result in contact welding or burning.

(6) Be sure to confirm the name and polarity for each terminal before wiring the terminal block and connectors. Faulty wiring causes destruction or burnout of internal parts.

(7) Use the product within the noted supply voltage and rated load.

(8) Do not connect anything to unused terminals.

(9) Output turns OFF when the mode is changed or settings are initialized. Take this into consideration when setting up the control system.

V

(10) Install an external switch or circuit breaker and label them clearly so that the operator can quickly turn OFF the power.

(11) Ensure that the rated voltage is achieved no longer than 2 s after turning the power ON.

When applying a voltage gradually, power supply may not be reset or output functions indeterminately.

(12) Mount to a panel between 1 and 5 mm thick.

(13) Use the specified size of crimp terminals (M3, width : 5.8 mm max.) for wiring. To connect bare wires, use AWG 28 to AWG 16 to wire the power supply terminals and

AWG 22 to AWG 14 for other terminals. (Length of exposed wire : 6 to 8 mm)

(14) Allow the product to operate without load for at least 15 minutes after the power is turned ON.

VI

Precautions for Correct Use

(1) Install the product horizontally. Display error has the risk of becoming larger than the standard because heat cannot be radiated.

(2) When using a noise filter on the power supply, check that the filter is suitable for the supply voltage and current ratings, and then attach the noise filter as close as possible to the K3GN.

Normal range

Note

The input type, analog range, scaling factor, and decimal point position should be set in this order.

Otherwise, auto-initialization of parameters may result in a failure in parameter setting.

If you specify the scaling factor and then the input type, for example, the analog range and the scaling factor are initialized automatically.

Flow of Initial Setting

A.

Check wiring for correct connection and power the product on.

The product is factory set to have an analog input range of 4 to 20 mA.

If an input that falls outside this default range is received, the main indicator of the product will read “s.err” and blink, indicating an

“input range over” error occurs.

B.

Set “input type” to “analog”.

1.

Make sure the main indicator displays a process value (the product is at the operation level).

Then press the L key and hold it down for at least one second.

The product will move to the initial setting level.

2.

Set parameter “in-t” to “analg”.

C.

Set “analog range” to “1 ~ 5V”.

1.

Set parameter “range” to “1-5”.

D.

Specify the scaling factor.

1.

Set parameter “inp.1” to “1.000”.

2.

Set parameter “dsp.1” to “0”.

3.

Set parameter “inp.2” to “5.000”.

4.

Set parameter “dsp.2” to “1000”.

1.

Set parameter “out1.t” to “hi”.

2.

Set parameter “out2.t” to “lo”.

G.

Set the OUT1 value to “70.0” and the OUT2 value to “50.0”.

1.

Make sure the main indicator displays an initial setting level parameter

(the product is at the initial setting level).

Then press the L key and hold it down for at least one second.

The product will move to the operation level.

2.

Set parameter “out1” to “70.0”.

3.

Set parameter “out2” to “50.0”.

H.

Bring the product into measuring operation.

TIPS

The number of measurements for averaging and the hysteresis can be changed if required.

These parameters are to be set at the advanced-function setting level.

Clear All

If you are confused about how parameters have been set during initial setting, you can clear all the parameters and start all over again.

For details on how to clear all parameters, refer to Section 5.16 Clearing All

Parameters.

For details on parameter setting, refer to CHAPTER 5 OPERATION.

CHAPTER 4 INITIAL SETTING

4.2 Using the Product as a Tachometer

The following example shows the flow of initial setting for the product that is used as a tachometer.

Setting example:

The speed of a conveyor belt is indicated in terms of m/min.

Four pulses are generated per rotation of the rotor.

The diameter of the rotor is 12 cm.

Comparative output 1 is produced when the speed reaches 10500 m/min.

Comparative output 2 is produced when the speed decreases to 9500 m/min. m/min

How to Determine the Scaling Factor

Determine the scaling factor as follows.

Rotor rotational speed (rpm)

= Input frequency (Hz)/Number of pulses per rotation × 60

Belt Speed (m/min)

Note

The input type, pulse frequency, scaling factor, and decimal point position should be set in this order.

Otherwise, auto-initialization of parameters may result in a failure in parameter setting.

If you specify the scaling factor and then the input type, for example, the pulse frequency and the scaling factor are initialized automatically.

Hence the belt speed is given as

Belt speed (m/min) = 3.14159… × 0.12 × 60/4 × Input frequency (Hz)

= 5.654866… × Input frequency (Hz)

Multiply the result by 1000 to enable a readout to be displayed to three decimal places.

Belt speed (m/min) = 5654.866… × Input frequency (Hz)

To minimize the scaling operation error, select such an input frequency that allows readouts to contain the largest possible number of digits. In this example, the input frequency is set to 10 Hz so that the readout is

56549.

Readout

CHAPTER 4 INITIAL SETTING

4.3 Using the Product as a Digital Indicator for PLC Data

The following example shows the flow of initial setting for the product that is used as a digital indicator for PLC data.

Setting example:

Full span 0H to 0FA0H (0 to 4000 in decimal) of a PLC analog input unit is scaled to 80.0 to 120.0 mm and displayed.

Comparative output 1 is produced when the process value reaches 110.0 mm.

Comparative output 2 is produced when the process value decreases to

90.0 mm.

Readout

120.0mm

80.0mm

Comparative output 2

Normal range

90.0mm

Comparative output 1

110.0mm

0 4000 Input signal

TIPS

Setting “input type” to

“remote” sets the adjustment level parameter “downloading

(communication writing)” to

“enable” automatically.

The "CMW" indicator on the front panel will be illuminated.

Note

The input type, scaling factor, and decimal point position should be set in this order.

Otherwise, auto-initialization of parameters may result in a failure in parameter setting.

If you specify the scaling factor and then the input type, for example, the scaling factor is initialized automatically.

CHAPTER 5 OPERATION

5.4 Set Values

Parameter settings are called “set values”.

Set values include those consisting of “numerics” and “alphabets”.

A state in which a set value is being displayed on the main indicator is called “the

monitor state”.

A state in which a set value can be changed is called “the change state”.

Perform the following steps to display or change a set value.

Procedure

A.

Press the S key when a parameter is displayed on the main indicator.

The product enters the monitor state and the set value of the parameter will be displayed on the main indicator.

• When the product is in the monitor state, “SV” in the operation indicator section is illuminated, indicating the readout on the main indicator is a set value.

B.

If you do not want to change the set value, press the M key in the monitor state to go to the next parameter.

TIPS

During setting of operation or adjustment level parameters, the return action of the product varies depending on the “display auto-return time” setting.

The display auto-return time defaults to ten seconds.

If the “display auto-return time” is set to less than five seconds, e.g., three seconds, no key operation for three seconds in the change state will return the product to the current value display mode, not to the monitor state.

C.

Press the S key in the monitor state to cause the product to enter the change state.

• A digit that can be changed will start blinking.

D.

Use the S and

/

ZERO

key to change the set value.

• If no key is operated for five seconds, the product saves the current value and returns to the monitor state automatically.

E.

Press the M key to go to the next parameter.

Forced-zero operation

Note

The forced-zero operation is not available if the input type is set to "pulse".

The forced-zero operation allows you to shift the current value to zero forcedly.

For details, refer to CHAPTER 6 FUNCTION DESCRIPTION.

Procedure

(for forced-zero operation)

A.

Press the

/

ZERO

key when a current value is displayed on the main indicator. (Release the key within one second).

• The current value will be shifted to zero.

• “ZERO” in the operation indicator section is illuminated, indicating the current value has been shifted to zero.

TIPS

If the

/

ZERO

key on the front panel is used for executing the forced-zero operation, the forced-zero process is stored in EEPROM. But if the forced-zero operation is executed via the event input terminal or communications, the process is not stored.

If the current value is not normal (e.g., the input signal is invalid, the process value is outside the displayable range, or no measurements are made), the forced-zero function is inoperative.

Procedure

(for forced-zero release operation)

B.

Press the

/

ZERO

key and hold it down for at least one second when a shifted value is displayed.

• The shifted value will be restored to the current value.

5.12 Specifying the Scaling Factor for Input Pulse Frequency

How to

Determine

Appropriate

Scaling Factors

To minimize the scaling operation error, select such a scaling factor that permits the largest possible number of digits to be contained in scaling display values

(DSP).

The relationship between the scaling input and display values for input pulse frequency is represented by the following equation.

Scaling display value =

α (multiplication factor) × input frequency (Hz)

Where α = DSP/INP

α is often an indivisible number such as 5.654866… particularly when the input value is converted to a circumferential velocity. This is because such a conversion involves

π.

There are innumerable combinations of scaling input values (INP) and scaling display values (DSP) that result in

α = 5.654866… as follows.

INP (Hz) DSP

1

2

5

10

···

5.654866···

11.30973···

28.27433···

56.54866···

On the other hand, DSPs that are programmable are limited to 5-digit integers.

This means that DSPs must be rounded off to the nearest integers as follows.

INP (Hz) Programmable DSP

1

2

5

10

···

00006

00011

00028

00057

Hence, if the input frequency is 1000 Hz, the error between the scaling result and the ideal value increases with the decreasing number of digits contained in the

DSP.

5.21 Specifying the Auto-zero Time

5.21 Specifying the Auto-zero Time auto.z

Advanced-function setting level

When the input type has been set to "pulse", this parameter allows you to specify the auto-zero time.

Before specifying the auto-zero time, you must set the input type to “pulse”.

(AUTO.Z)

Parameter Set value Description auto.z

0.0 ~ 19.9

0.0 to 19.9 seconds: Auto-zero time

The auto-zero time is the length of time required for the product to return the readout to zero after pulse input interruption.

Set this parameter to a larger value than the expected time interval of input pulses

(interval between input pulses). Failure to do so will result in incorrect measurements.

If the auto-zero time is too long, on the other hand, a long delay in lower-limit action in response to a stop of rotation may result.

In the following application where a pulse is produced per rotation, for example, the input pulse frequency is 0.2 to 100 Hz, which means the time interval of input pulses is 0.01 to 5 seconds.

The auto-zero time should therefore be set to five seconds or longer.

1

= 5 (seconds)

The product has an input-pulse frequency range of 0.05 to 30 Hz or 0.1 to 5 kHz, and hence the maximum interval between pulses is 20 seconds.

This means that the product may provide a lower-limit action signal as late as a maximum of 20 seconds after receiving the last pulse, which results in a poor responsivity for the lower-limit action.

Input pulse

Pulse frequency

OUT set value

(Lower-limit action)

Auto-zero time

Comparative output

(Auto-zero function activated)

Comparative output

(Auto-zero function canceled)

To eliminate such a situation, the product has an auto-zero function that shifts the input pulse frequency to zero forcedly when no pulse is received for a predetermined time.

This function improves the product responsivity for the lower-limit action.

The time between reception of the last pulse and zero-shifting of the input pulse frequency is called the auto-zero time. The auto-zero time can be specified using the “auto-zero time” parameter.

Specify the auto-zero time somewhat longer than the expected longest interval between input pulses.

Startup Compensation

The product has a startup compensation timer that prevents measurement for a predetermined time after power-on.

This function is useful in keeping the product in wait state until a rotator reaches the steady-state speed.

The time between power-on the product and the start of measurement can be specified using the “startup compensation time” parameter.

6.4 Average Processing

6.4 Average Processing

This function averages a specified number of measurements.

It is useful for preventing readouts from fluctuating due to unstable input.

The average processing of the product provides a simple average (an arithmetic mean).

The number of measurements for averaging that can be specified is as follows.

- No average processing (the number of measurements for averaging: 1)

- 2

- 4

- 8

The number of measurements for averaging is the number of times the process value is updated as described in Section 6.1.

The following shows the relationship between the number of measurements for averaging and the interval at which the process value and comparative output are updated.

CHAPTER 6 FUNCTION DESCRIPTION

6.5 Event Input/Pulse Input

Terminal acts as the event input terminal when the input type is set to "analog" or "remote" and as the pulse input terminal when the input type is set to "pulse".

The event input terminal can be assigned the task of “process value hold” or

“forced-zero”. This assignment depends on setting of the “event input” parameter at the advanced-function setting level.

Pulse input

The minimum pulse width of ON/OFF signals recognizable to the product varies between the event and pulse inputs.

For event input

When terminal is used for event input, chattering noise is removed from input signals and therefore devices of contact output type can be connected to the terminal.

The chattering noise removal processing suppresses signal fluctuations that occur within 30 to 40 ms after the input signal turns on or off.

Both ON and OFF pulses must therefore have at least 40 ms in width.

40ms min.

40ms min.

Chattering noise removed

For pulse input

When terminal is used for pulse input, devices of low-speed contact output type or high-speed transistor output type can be connected to the terminal depending on parameter setting.

When using a device of low-speed contact output type, set the input pulse frequency to “30 Hz”. In this case, chattering noise is removed and accordingly both ON and OFF pulses must have at least 15 ms in width.

When using a device of high-speed transistor output type, set the input pulse frequency to “5 kHz”. In this case, both ON and OFF pulses must have at least

90

6.6 Process Value Hold

6.6 Process Value Hold

TIPS

The “process value hold” function is available only when the input type is set to

"analog" or "remote" and terminal

is assigned the task of “process value hold”.

This function detects the process value at the instant when the event input turns on, and holds the value as long as the event input is on.

It can be used to hold the process value detected when a failure occurs.

“Process value hold” takes place via the event input terminal.

The following illustrates the “process value hold” operation.

Process value

HOLD input

The minimum input time for HOLD signal is 80ms.

• When the event input (HOLD) turns on, the process value is detected and held.

• If the input value changes, the process value continues to be held as long as the event input is on.

• When the event input (HOLD) turns off, the “process value hold” function is canceled and the display returns to the current value.

91

CHAPTER 6 FUNCTION DESCRIPTION

6.7 Forced-zero

Note

The forced-zero function is not available when the input type is set to "pulse". Key entry for the forced-zero operation is also ignored.

This feature shifts a process value to zero, and can be used to evaluate and display the deviation of a process value from a reference value.

The forced-zero function can be activated by using the panel, via the event input terminal, or communications

/

ZERO

key on the front

The following illustrates the forced-zero and forced-zero cancel operation.

TIPS

The forced-zero function is available via the event input terminal only when the input type is set to "analog" or

"remote" and terminal is assigned the task of

“forced-zero execution”.

Process value

ZERO input

The minimum input time for HOLD signal is 80ms.

• When ZERO input turns on, the current process value is shifted to zero forcedly.

• Thereafter, measurements are made relative to the zero point.

• When ZERO input turns on while the forced-zero function has been activated, the current process value is further shifted to zero.

• When ZERO input is on for one second, the forced-zero operation is canceled.

Because the forced-zero and forced-zero cancel operation using the and on again.

/

ZERO

key is stored in EEPROM, the forced-zero state is alive even if the power is turned off

In contrast, the forced-zero and forced-zero cancel operation via event input terminal is not stored in EEPROM.

If the forced-zero operation is executed via the event input terminal after it is activated by key entry, the forced-zero operation via the event input terminal takes effect.

In this manual, hysteresis refers to a range that is provided above or below an

OUT set value in order to avoid comparative output from turning off unless the process value falls outside the range, once the comparative output has turned on at the OUT set value.

CHAPTER 7 COMMUNICATIONS

7.1 Communication Protocols

CompoWay/F Communication Protocol

TIPS

The program for communications is created on the host PC , and K3GN's parameters are monitored or set from the host PC. In this manual, consequently, an explanation for communications is given from the standpoint of the host PC.

CompoWay/F is an OMRON's standard communication format for general serial communications. It uses a standard frame format as well as FINS commands that have been proven in data exchange between OMRON's programmable logic controllers. The CompoWay/F format facilitates serial communications between components or a PC and components.

FINS (Factory Interface Network Service)

FINS is a protocol for message communications between controllers in OMRON

FA networks.

Transmission Procedure

Comminations between the product and the host PC are implemented on a frame-by-frame basis.

When the host PC sends a command frame to the product, the product returns to the host PC a response frame that corresponds to the command frame.

Command and response frames are transmitted as follows.

7.2 Data Format Structure

7.2 Data Format Structure

Comminations conforming to the CompoWay/F serial communication format involve transmission of blocks of data that are called frames. Those sent from the host PC are command frames and those from the product are response frames.

The structure of these frames is shown below.

In the following frame description, suffix H added to a numeric value, as in 02H, means the value is a hexadecimal number. And double quotation marks in which an alphanumeric value is enclosed, as in “00”, mean that the value is an ASCII character set.

The number underneath each delimiter in a frame indicates the number of bytes.

CHAPTER 7 COMMUNICATIONS

7.4 Variable Area

A section of memory in the product that holds data to be transmitted is called the

variable area.

The variable area is used for reading of current process values or reading/writing of various parameters.

In contrast, the variable area is not used for operation instructions or reading of controller attributes.

To specify the position of a variable in the variable area, use a variable type and an address.

Append to each variable type an access-size-based address that is expressed in

2-byte hexadecimal code

A variable has an eight-digit value in hexadecimal. A negative variable is expressed in two’s complement. When the current value of a variable is read as

105.0

on the main indicator of the product, for example, its hexadecimal notation is 0000041AH (the decimal point is ignored; 105.0

→ 1050 → 0000041AH), and the variable is read in this form.

CHAPTER 7 COMMUNICATIONS

7.8 Setting Areas

The K3GN series of products can assume two states that are refereed to as setting

area 0 and setting area 1 in this manual.

In setting area 0, the product is carrying out a measurement.

In this state, you can therefore perform such operations that are permitted only during measuring, or that cause no trouble even if a measurement is in progress.

These operations include “process value reading”, “parameter writing” and

“forced-zero execution”.

On the contrary, this state prohibits such operations that exert an effect on measurement in progress, including “parameter writing at the initial setting level”

(parameter reading is always allowed).

In setting area 1, measurement is suspended.

In this state, you can therefore perform such operations that are not allowed in setting area 0. These operations include “parameter writing at the initial setting, communication setting, and advanced-function setting levels”.

At power-on, the product is in setting area 0. To move to setting area 1, use the “move-to-setting area 1” instruction. To return to setting area 0, power the product off and on again, or use the “software reset” instruction.

A transition to the initial setting level by key operation implies a transition from setting area 0 to setting area 1.

This enables the host PC to operate the product in setting area 1.

A transition to setting area 1 by remote control from the host PC causes the level indicator on the front panel to indicate the product is at the initial setting level. To return to the operation level, use the L key.

TIPS

Block access to the variable area

A number of contiguously addressed variables of the same type in the variable area can be accessed at a time.

For example, you can read the current value and the status simultaneously by setting the read start address to the address of the current value and setting the No. of elements to 2.

Such an access method is called “block access”.

Protocol Macro

What is the protocol macro?

Connection

The protocol macro is a ladder routine that, using a PMCR command, provides control to the sequence (protocol) of data communications between PLCs or other communication devices connected via RS-232C or RS-422A/485 interface.

OMRON’s CS1W series of serial communication boards come standard with a standard system protocol that allows control of OMRON’s components.

For details on the protocol macro, refer to the User’s Manual for Model

CS1W-SCB21/41/-SCU21 (Cat. No. W336-01).

The serial communication board CS1W-SCB41 has two ports, port 2 of which allows direct connection via RS-485 interface.

Use this port to connect the board to the product.

CHAPTER 8 USER CALIBRATION

8.1 User Calibration

Entry of

Calibration data

As the product has been calibrated at the factory, it does not need to be calibrated in normal use.

The product has the capability of analog input calibration, which enables user calibration as needed.

OMRON assumes no responsibility for the result of user calibration.

Note that, once user calibration is performed, original calibration data is overwritten and cannot be restored.

Devices and tools necessary for user calibration must be made available by the user. For handling of these devices, refer to their respective manuals.

First store both of calibration values 1 and 2 temporarily. Then save them while the product is in the change state.

Calibration data cannot be saved normally unless calibration values 1 and 2 are both specified.

If calibration data is saved normally, the product keeps a record of the user calibration. When you enters the user calibration level, a calibration record mark will appear on the main indicator as shown below.

9.2 Troubleshooting Table

9.2 Troubleshooting Table

Symptom

The forced-zero function is inoperative even though the

/

ZERO

key is pressed.

Probable cause

The “input type” parameter is set to “pulse”.

Forced-zero lockout is active. At the protect level, set the forced-zero function to

“enable”.

Remedy

The forced-zero function is not available.

Reference page

50

92

48

The product does not enter the protect level even though the L

+ M is held down for 5 seconds.

The “move-to-protect-level” parameter is set to a value more than 5.

Set the “move-to-protect-level” parameter to an appropriate value.

79

Readouts vary greatly or decrease with increasing rotational speed.

The “input-pulse frequency range” parameter is set to “30

Hz”.

The input pulse frequency exceeds 5 kHz.

If the input pulse frequency exceeds 30 Hz, set the

“input-pulse frequency range” parameter to “5 kHz”.

Lower the input pulse frequency to 5 kHz or less.

Note that the product does not generate an out-of-range error if the input pulse frequency exceeds 5 kHz.

52

90

Readouts vary or are incorrect even when the rotational speed is low.

The pulse width of ON/OFF signals is too small.

Supply the product with pulses that have a width specified in this manual.

The product cannot recognize input pulses correctly unless their width is as specified, even if the rotational speed is low.

90

The main indicator reads 0 when the rotational speed is low.

The “auto-zero time” parameter is set to a value that is not more than the maximum time interval of input pulses.

Set the “auto-zero time” parameter to a value exceeding the maximum time interval of input pulses.

Otherwise, the auto-zero function may be triggered improperly.

135

TROUBLESHOOTING GUIDE

Symptom

The product continues to read

“00000” on the main indicator since powered on.

The event/pulse input terminals cannot be turned on or off at all or sometimes.

The product does not return responses at all to the host PC.

Comparative output does not turn off even when a process value goes back to normal.

Probable cause Remedy

Reference page

The set value of the “startup compensation timer” parameter is too large.

Set the “startup compensation timer” parameter to an appropriate value.

When the input type is set to

"pulse", the startup compensation time can be set to up to 99.9 seconds.

73

88

The “process value hold” function is active.

Cancel “process value hold”.

If the event input terminal is used for “process value hold”, powering on the product in the

ON state of the terminal will result in a readout of “00000”, which is retained unless the terminal turns off.

91

The making residual current and/or breaking leakage current of input equipment are outside the specified limits.

Use such input equipment that conforms to the requirements of the making residual current and breaking leakage current specifications.

Otherwise, the product cannot detect the ON/OFF signals from input equipment.

13

Wiring is incorrect. Check wiring for correct connection and A/B polarity.

14

The command frame contains a wrong unit No.

Specify a correct unit No.

Otherwise, the product will not return a response to the host PC.

99

The set value of the “hysteresis” parameter is too large.

Set the “hysteresis” parameter to an appropriate value.
