• Use a solderless terminal with an insulation sleeve in which the M3 screw fits when wiring the WIL-101-ORP.

• Tighten the terminal screw using the specified torque. If excessive force is applied to the screw when tightening, the terminal screw may be damaged.

• This instrument does not have a built-in power switch, circuit breaker and fuse.

It is necessary to install a power switch, circuit breaker and fuse near the instrument. (Recommended fuse: Time-lag fuse, rated voltage 250 V AC, rated current 2 A)

• For a 24 V AC/DC power source, do not confuse polarity when using direct current (DC).

• Do not apply a commercial power source to the sensor which is connected to the input terminal nor allow the power source to come into contact with the sensor.

• Use the ORP Combined Electrode Sensor in accordance with the sensor input specifications of the WIL-101-ORP.

• Keep the input wires and power line separate.

Note about the ORP Combined Electrode Sensor Cable

The ORP Combined Electrode Sensor cable is a highly-insulated (electrical) cable. Please handle it with utmost care as follows.

• Do not allow terminals and socket of the ORP Combined Electrode Sensor cable to come in contact with moisture or oil of any kind. Likewise, ensure fingers are clean, otherwise the insulation will deteriorate, resulting in unstable indication. Be sure to keep the cable dry and clean at all times. If the cable is stained, clean it with alcohol, and dry it completely.

• For calibration or electrode checking/replacement, the ORP Combined Electrode Sensor cable should be wired with sufficient length.

• Keep the ORP Combined Electrode Sensor cable and junction cable away from electrical devices, such as motors or their power lines from which inductive interference emanates.

Connection

Shield Wire

Be sure to ground only one end of the shield wire so that current cannot flow to the shield wire. If both ends of the shield wire are grounded, the circuit will be closed, resulting in a ground loop.

This may cause noise. Be sure to ground the FG terminal.

Recommended cable: OTSC-VB 2PX0.5SQ (made by Onamba Co., Ltd.) or equivalent

(Use a twisted pair cable.)

Terminator (Terminal Resistor)

The terminator is mounted at the end of the wire when connecting a personal computer with multiple peripheral devices. The terminator prevents signal reflection and disturbance. Do not connect a terminator with the communication line because each WIL-101-ORP has built-in pull-up and pull-down resistors instead of a terminator. Communication converter IF-400 (sold separately) has a built-in terminal resistor.

10.2 A Output

When (ORP input low limit action), (ORP input high limit action) is selected in [A11, A12, A21, A22 type (pp.21, 22)], the A output is turned ON if ORP value exceeds the A value. A1 or A2 output is turned ON depending on the settings in [A1, A2 output allocation (p.28)] and [Output ON time/OFF time when A1/A2 output ON (p.29)]. However, if (Cleansing output) is selected in any of [A11, A12, A21, A22 type (pp.21, 22)], the Cleansing output will be given priority.

If ON time and OFF time are set, A1 or A2 output can be turned ON/OFF in a configured cycle when A1 or A2 output is ON. (Fig. 10.2-1)

Timing chart of Output ON time and OFF time while in A1 output ON

(Fig. 10.2-1)

A output status can be read by the status flag (A11, A12, A21, A22 output bit) in Serial communication. A output status, when input errors occur, differs depending on the selection in [A output when input errors occur (p.20)].

• If (Disabled) is selected, A output and A output status will be turned OFF when input errors occur.

• If (Enabled) is selected,A output and A output status will be maintained when input errors occur.

10.3 ORP Input Error Alarm

ORP input error alarm is used for detecting actuator trouble. Even if ORP input error alarm time has elapsed, and if ORP input does not become higher than ORP input error alarm span, the unit assumes that actuator trouble has occurred, and writes Status flag 2. In Serial communication, status can be read by reading Status flag 2 (A1, A2 ORP input error alarm output flags).

ORP input error alarm is disabled in the following cases.

• During Adjustment Mode, Span Sensitivity Correction Mode.

• When (Cleansing output) is selected in any of [A11, A12, A21, A22 type (pp.21, 22)], and

cleansing action is performing using the ‘Cleansing time’ and ‘Restore time after cleansing’ settings.

• When ORP input error alarm time is set to 0 seconds, or ORP input error alarm span is set to 0 mV

10.4 Cleansing Output

If (Cleansing output) is selected in any one of [A11, A12, A21, A22 type (pp.21, 22)], the unit will enter Cleansing Output mode. An A output (for which the cleansing output is selected) will turn ON during the configured cleansing time. When the cleansing interval finishes after restore time has passed, this is counted as one cleansing cycle, and the configured number of cleansing cycles will be repeated. While cleansing is being performed using the ‘Cleansing Time’ and ‘Restore Time after Cleansing’ settings, other outputs are in OFF status. ORP value is retained.

When cleansing is not being performed, programmed operation continues. When power is turned ON again, the unit starts from the first cleansing cycle. After the configured number of cleansing cycles are finished, the A output (for which the cleansing output is selected) is turned OFF, and other outputs perform their programmed operations, however, they are in Cleansing Output mode.

• While A1 is performing cleansing action, and if A type (to which Cleansing output is set) is selected for A2, A2 cleansing action will be the same as the (currently performing) A1 cleansing action.

While A2 is performing cleansing action, and if A type (to which Cleansing output is set) is selected for A1, A1 cleansing action will be the same as the (currently performing) A2 cleansing action.

• During Adjustment Mode, Span Sensitivity Correction Mode or Transmission Output Mode, if cleansing action initiates after restore time has passed, the cleansing action will not be performed in the current session.

• If the number of cleansing cycles is changed in [Number of cleansing cycles] during cleansing action, the new number will be valid from the next cleansing cycle.

If any output other than (Cleansing output) is selected in [A11, A12, A21, A22 type (pp.21,

22)], the unit will revert to ORP Display Mode.

10.5 Manual Cleansing Mode

By pressing the and keys simultaneously for 3 seconds, the unit enters Manual Cleansing Mode. In Manual Cleansing Mode, cleansing action is performed using the ‘Cleansing Time’ and ‘Restore Time after Cleansing’ settings. After cleansing is completed, the unit automatically reverts to Cleansing Output Mode.

During cleansing action, manual cleansing via key operation is invalidated, so the unit cannot move to Manual Cleansing Mode. During Manual Cleansing Mode, if Programmed cleansing action initiates after Restore time has passed, the cleansing action will not be performed in the current session. Cleansing action by Manual Cleansing Mode is counted as 1 cleansing cycle.

11.3 Communication Procedure

Communication starts with command transmission from the host computer (hereafter Master) and

ends with the response of the WIL-101-ORP (hereafter Slave).

• Response with Data

When the master sends the reading command, the slave responds with the corresponding set value or current status.

• Acknowledgement

When the master sends the setting command, the slave responds by sending acknowledgement after processing is terminated.

• Negative Acknowledgement

When the master sends a non-existent command or value out of the setting range, the slave returns a negative acknowledgement.

• No Response

The slave will not respond to the master in the following cases:

• Global address (Shinko protocol) is set.

• Broadcast address (Modbus protocol) is set.

• Communication error (framing error, parity error)

• Checksum error (Shinko protocol), LRC discrepancy (Modbus

(Fig.11.3-1) ASCII mode), CRC-16 discrepancy (Modbus RTU mode)

Communication Timing of the RS-485

Master Side (Take note while programming)

When the master starts transmission through the RS-485 communication line, the master is arranged so as to provide an idle status (mark status) transmission period of 1 or more characters before sending the command to ensure synchronization on the receiving side. Set the program so that the master can disconnect the transmitter from the communication line within a 1 character transmission period after sending the command in preparation for reception of the response from the slave. To avoid collision of transmissions between the master and the slave, send the next command after carefully checking that the master has received the response. If a response to the command is not returned due to communication errors, set the Retry Processing to send the command again. (It is recommended to execute Retry twice or more.)

Slave Side

When the slave starts transmission through the RS-485 communication line, the slave is arranged so as to provide an idle status (mark status) transmission period of 1 or more characters before sending the response to ensure synchronization on the receiving side. The slave is arranged so as to disconnect the transmitter from the communication line within a 1 character transmission period after sending the response.

11.4.1 Transmission Mode

Shinko protocol is composed of ASCII. Hexadecimal (0 to 9, A to F), which is divided into high order (4-bit) and low order (4-bit) out of 8-bit binary data in command is transmitted as ASCII characters. Data format Start bit: 1 bit

Data bit: 7 bits Parity: Even Stop bit: 1 bit

Error detection: Checksum

11.4.2 Command Configuration

All commands are composed of ASCII. The data (set value, decimal number) is represented by hexadecimal numbers. The negative numbers are represented in 2's complement. Numerals written below the command represent the number of characters.

Instrument Number (Address): Numbers by which the master discerns each slave.

Instrument numbers 0 to 94 and Global address 95. ASCII codes (20H to 7FH) are used by adding 20H to instrument numbers 0 to 95 (00H to 5FH). 95 (7FH) is called Global address, which is used when the same command is sent to all the slaves connected. However, the response is not returned.

5 (35H)-----During setting mode by keypad operation

11.4.3 Checksum Calculation

Checksum is used to detect receiving errors in the command or data. Set the program for the master side as well to calculate the checksum of the response data from the slaves so that communication errors can be checked. The ASCII code (hexadecimal) corresponding to the characters which range from the address to that before the checksum is converted to binary notation, and the total value is calculated. The lower one byte of the total value is converted to 2’s complement, and then to hexadecimal numbers, that is, ASCII code for the checksum.

Checksum Calculation Example

Data item 0008H (Moving average data amount): 1 (0001H) Address (instrument number): 0 (20H)

• 1’s complement: Reverse each binary bit. 0 will become 1 and vice versa.

• 2’s complement: Add 1 to 1’s complement.

11.5 Modbus Protocol

11.5.1 Transmission Mode

There are 2 transmission modes (ASCII and RTU) in Modbus protocol.

ASCII Mode

Hexadecimal (0 to 9, A to F), which is divided into high order (4-bit) and low order (4-bit) out of 8-bit binary data in command is transmitted as ASCII characters. Data format Start bit: 1 bit

Data bit: 7 bits Parity: Even (No parity, Odd), Selectable Stop bit: 1 bit (2 bits). Selectable

Error detection : LRC (Longitudinal Redundancy Check)

RTU Mode

8-bit binary data in command is transmitted as it is. Data format Start bit: 1 bit

Data bit: 8 bits Parity: No parity (Even, Odd), Selectable Stop bit: 1 bit (2 bits). Selectable

Error detection: CRC-16 (Cyclic Redundancy Check)

11.5.2 Data Communication Interval ASCII Mode

1 second or less Max.1 second of interval between ASCII mode characters

RTU Mode

3.5 character transmission times or less To transmit continuously, an interval between characters which consist of one message, must be within 3.5 character transmission times. If an interval lasts longer than 3.5 character transmission times, WIL-101-ORP assumes that transmission from the master is finished, which results in a communication error, and will not return a response.

11.5.3 Message Configuration

(1) Slave Address

Slave address is an individual instrument number on the slave side, and is set within the range 0 to 95 (00H to 5FH). The master identifies slaves by the slave address of the requested message. The slave informs the master which slave is responding to the master by placing its own address in the response message. Slave address 00H (Broadcast address) can identify all the slaves connected. However slaves do not respond.

(2) Function Code

The function code is the command code for the slave to undertake the following action types.

(Table 11.5.3-1)

Function Code

Contents

03 (03H) Reading the set value and information from slaves 06 (06H) Setting to slaves

Function code is used to discern whether the response is normal (acknowledgement) or if any error (negative acknowledgement) has occurred when the slave returns the response message to the master. When acknowledgement is returned, the slave simply returns the original function code. When negative acknowledgement is returned, the MSB of the original function code is set as 1 for the response. (For example, when the master sends request message setting 10H to the function code by mistake, slave returns 90H by setting the MSB to 1, because the former is an illegal function.) For negative acknowledgement, the exception codes below (Table 11.5.3-2) are set to the data of the response message, and returned to the master in order to inform it of what kind of error has occurred.

(Table 11.5.3-2)

Exception Code Contents

1 (01H) Illegal function (Non-existent function) 2 (02H) Illegal data address (Non-existent data address) 3 (03H) Illegal data value (Value out of the setting range)

17 (11H)

Shinko protocol error code 4 [Status unable to be set (e.g.) During

Adjustment Mode, Span Sensitivity Correction Mode or Transmission output adjustment, etc.]

18 (12H) Shinko protocol error code 5 (During setting mode by keypad operation)

(3) Data

Data differs depending on the function code. A request message from the master is composed of data item, amount of data and setting data. A response message from the slave is composed of a number of bytes, data and exception codes in negative acknowledgements, corresponding to the request message.

Effective range of data is -32768 to 32767 (8000H to 7FFFH).

(4) Error Check

ASCII Mode

After calculating LRC (Longitudinal Redundancy Check) from the slave address to the end of data, the calculated 8-bit data is converted to two ASCII characters, and are appended to the end of message.

How to Calculate LRC

Create a message in RTU mode.

Add all the values from the slave address to the end of data. This is assumed as X.

Make a complement for X (bit reverse). This is assumed as X.

Add a value of 1 to X. This is assumed as X.

Set X as an LRC to the end of the message.

Convert the whole message to ASCII characters.

RTU Mode

After calculating CRC-16 (Cyclic Redundancy Check) from the slave address to the end of the data, the calculated 16-bit data is appended to the end of message in sequence from low order to high order.

How to calculate CRC-16

In the CRC-16 system, the information is divided by the polynomial series. The remainder is added

to the end of the information and transmitted. The generation of a polynomial series is as follows. (Generation of polynomial series: X16+ X15+ X2+ 1)

Initialize the CRC-16 data (assumed as X) (FFFFH).

Calculate exclusive OR (XOR) with the 1st data and X. This is assumed as X.

Shift X one bit to the right. This is assumed as X.

When a carry is generated as a result of the shift, XOR is calculated by X of3and the fixed value (A001H). This is assumed as X. If a carry is not generated, go to step5.

Repeat steps3and4until shifting 8 times.

XOR is calculated with the next data and X. This is assumed as X.

Repeat steps3to5.

Repeat steps3to5up to the final data.

Set X as CRC-16 to the end of message in sequence from low order to high order.

11.6 Communication Command Table

11.6.1 Notes about Setting/Reading Command

• The data (set value, decimal) is converted to hexadecimal numbers. A negative number is represented in 2's complement.

• When connecting multiple slaves, the address (instrument number) must not be duplicated.

• Data item 0200H to 0209H (User save area 1 to 10) can be read or set in 1 word units.

Effective range of data is -32768 to 32767 (8000H to 7FFFH).

• Modbus protocol uses Holding Register addresses. The Holding Register addresses are created

as follows. A Shinko command data item is converted to decimal number, and the offset of 40001 is added. The result is the Holding Register address. Using Data item 0001H (Input high limit) as an example:

Data item in the sending message is 0001H, however, Modbus protocol Holding Register address is 40002 (1 + 40001).

• Even if options are not ordered, setting or reading via software communication will be possible.

Command contents of the A11, A12, A21, A22 will function, however, Transmission output command contents will not function.

(1) Setting Command

• Up to 1,000,000 (one million) entries can be stored in non-volatile IC memory. If the number of settings exceeds the limit, the data will not be saved. So, ensure the set values are not frequently changed via software communication. (If a value set via software communication is the same as the value before the setting, the value will not be written in non-volatile IC memory.)

• Be sure to select Lock 3 when changing the set value frequently via software communication. If Lock 3 is selected, all set values – except Adjustment value, Span sensitivity correction value, Transmission output Zero adjustment value, Transmission output Span adjustment value – can be temporarily changed. However, they revert to their previous value after the power is turned off because they are not saved in the non-volatile IC memory. Do not change setting items A11, A12, A21 and A22 types. If they are changed, they will affect other setting items.

• Setting range of each item is the same as that of keypad operation.

• When the data (set value) has a decimal point, a whole number (hexadecimal) without a decimal point is used.

• If A type is changed in [A11, A12, A21, A22 type] (A11: 0003H, A12: 0050H, A21: 0051H, A22: 0052H), the A11, A12, A21 or A22 value (A11: 0004H, A12: 0053H, A21: 0054H, A22: 0055H) will default to 0 (zero). Output status of A11, A12, A21 or A22 will also be initialized.

• Settings via software communication are possible while in Set value lock status.

• The Instrument Numbers and Communication Speed of the slave cannot be set by the software communication function. They can only be set via the keypad.

• When sending a command by Global address [95 (7FH), Shinko protocol] or Broadcast address [0 (00H), Modbus protocol], the same command is sent to all the slaves connected. However, the response is not returned.

(2) Reading Command

• When the data (set value) has a decimal point, a whole number (hexadecimal) without a decimal point is used for a response.

11.7 ORP Calibration and Transmission Output Adjustment via Communication Command

Like a keypad operation, there are also 2 methods in calibration via communication command:

Adjustment Mode and Span Sensitivity Correction Mode

11.7.1 Adjustment Mode

When using a brand-new sensor, please calibrate in Adjustment Mode.

The following outlines the procedure for calibration.

When selecting Last value HOLD (0000H) at Data item 010FH (Transmission output status in Adjustment Mode, Span Sensitivity Correction Mode), select it while the ORP Combined Electrode Sensor is being immersed in the solution currently calibrated.

Set Data item 0044H (Adjustment Mode) to 0001H. The unit enters Adjustment Mode.

Immerse the ORP Combined Electrode Sensor in the standard solution (Quinhydrone potential

difference 260 mV).

Set the adjustment value at Data item 0045H (Adjustment value) so that ORP value is 260 mV (at 20 ).

For other temperature and electrical potentials, refer to the temperature characteristics of your standard solution. If 212digit is read at Data item 0081H (Status flag 1), 1 (Adjustment Mode) will be returned.

Set Data item 0044H (Adjustment Mode) to 0000H.

Adjustment Mode is complete, and the unit will revert to ORP Display Mode or Cleansing Output Mode. If 212digit is read at Data item 0081H (Status flag 1), 0 (ORP Display Mode or Cleansing Output Mode) will be returned.

If errors (e.g. ORP value is outside the measurement range) occur in Adjustment Mode, and if adjustment cannot be carried out, Error code 1 (Exceeding 1999 mV, Less than -1999 mV) will be returned when 29and 210digits are read at Data item 0081H (Status flag 1). To cancel the error code, set Data item 0044H (Adjustment Mode) to 0000H.

The unit will revert to ORP Display Mode or Cleansing Output Mode.

11.7.2 Span Sensitivity Correction Mode

When calibrating periodically, please calibrate in Span Sensitivity Correction Mode.

The following outlines the procedure for calibration.

Set Data item 0046H (Span Sensitivity Correction Mode) to 0001H. The unit enters Span Sensitivity Correction Mode.

Immerse the ORP Combined Electrode Sensor in the Standard solution (Quinhydrone potential

difference 260 mV).

Set the span sensitivity correction value at Data item 0047H (Span sensitivity correction

value) so that ORP value is 260 mV (at 20 ). For other temperature and electrical potentials, refer to the temperature characteristics of your standard solution. If 213digit is read at Data item 0081H (Status flag 1), 1 (Span Sensitivity Correction Mode) will be returned.

Set Data item 0046H (Span Sensitivity Correction Mode) to 0000H.

Span Sensitivity Correction Mode is complete, and the unit will revert to ORP Display Mode or Cleansing Output Mode. If 213digit is read at Data item 0081H (Status flag 1), 0 (ORP Display Mode or Cleansing Output Mode) will be returned.

If errors (e.g. ORP value is outside the measurement range) occur in Span Sensitivity Correction Mode, and if span sensitivity correction cannot be carried out, Error code 1 (Exceeding 1999 mV, Less than -1999 mV) will be returned when 29and 210digits are read at Data item 0081H (Status flag 1). To cancel the error code, set Data item 0046H (Span Sensitivity Correction Mode) to 0000H. The unit will revert to ORP Display Mode or Cleansing Output Mode.

11.7.3 Transmission Output Adjustment

Fine adjustment of Transmission output is performed. This ORP meter is adjusted at the factory, however, differences may occur between the indication value of the connected equipment (recorders, etc.) and output value of this instrument. In this case, perform Transmission output Zero adjustment and Span adjustment.

The following outlines the procedure for adjustment.

Set Data item 0126H (Transmission Output Adjustment Mode) to 0001H.

The unit moves to Transmission Output Zero Adjustment Mode. If 212, 211digits are read at Data item 0091H (Status flag 2), 01 (During transmission output Zero adjustment in Transmission Output Adjustment Mode) will be returned.

Set the Transmission output Zero adjustment value at Data item 0127H (Transmission output

Zero adjustment value), while viewing the value displayed on the connected equipment (recorders, etc.). Setting range: 5.00% of Transmission output span

Set Data item 0126H (Transmission Output Adjustment Mode) to 0002H.

The unit moves to Transmission Output Span Adjustment Mode. If 212, 211digits are read at Data item 0091H (Status flag 2), 10 (During transmission output Span adjustment in Transmission Output Adjustment Mode) will be returned.

Set the Transmission output Span adjustment value at Data item 0128H (Transmission output

Span adjustment value), while viewing the value displayed on the connected equipment (recorders, etc.). Setting range: 5.00% of Transmission output span

Repeat steps

if necessary.

To finish the Transmission output adjustment, set Data item 0126H (Transmission Output

Adjustment Mode) to 0000H. The unit reverts to ORP Display Mode or Cleansing Output Mode.

11.8 Notes on Programming Monitoring Software

11.8.1 How to Speed up the Scan Time

When monitoring multiple units of the WIL-101-ORP, set the program so that the requisite minimum pieces of data such as Data item 0080H (ORP value), Data item 0081H (Status flag 1), Data item 0091H (Status flag 2) can be read. For other data, set the program so that they can be read only when their set value has been changed. This will speed up the scan time.

11.8.2 How to Read the Set Value Changes Made by Front Keypad Operation

If any set value is changed by keypad operation, the instrument sets [0081H (Status flag 1) 215: Change in key operation] to 1 (Yes). There are 2 methods of reading the set value changes made by the front keypad:

(1) Reading Method 1

On the monitoring software side, check that [0081H (Status flag 1) 215: Change in key

operation] has been set to 1 (Yes), then read all set values.

Clear [0081H (Status flag 1) 215: Change in key operation], by setting Data item 007FH (Key operation change flag clearing) to 0001H (Clear change flag). If 007FH (Key operation change flag clearing) is set to 0001H (Clear change flag) during the setting mode of the instrument, Error code 5 (35H, Shinko protocol) or Exception Code 18 (12H, Modbus protocol) will be returned as a negative acknowledgement. And [0081H (Status flag 1) 215: Change in key operation] cannot be cleared. Set a program so that all set values can be read when a negative acknowledgement is returned.

Read all set values again after acknowledgement is returned.

(2) Reading Method 2

On the monitoring software side, check that [0081H (Status flag 1) 215: Change in key

operation] has been set to 1 (Yes), then set 007FH (Key operation change flag clearing) to 0001H (Clear change flag).

Set the program depending on the acknowledgement or negative acknowledgement as follows.

When acknowledgement is returned:

Consider it as settings completed, and read all set values.

When Error code 5 (35H, Shinko protocol) or Exception code 18 (12H, Modbus protocol) is returned as a negative acknowledgement:

Consider it as still in setting mode, and read the requisite minimum pieces of data such as 0080H (ORP value), 0081H (Status flag 1), 0091H (Status flag 2), then return to step1.

Thus, programs which do not affect the scan time can be created using the methods described above, even if set values on the monitoring software will not be updated until settings are complete.

11.8.3 Note when Sending All Set Values Simultaneously

• If A11, A12, A21 or A22 type is changed at Data item 0003H (A11 type), 0050H (A12 type), 0051H (A21 type) or 0052H (A22 type), the A11, A12, A21 or A22 value will default to 0 (zero). Output status of A11, A12, A21 or A22 will also be initialized.

First, send the A11, A12, A21, A22 type, then send the A11, A12, A21, A22 value set at Data item 0004H (A11 value), 0053H (A12 value), 0054H (A21 value) and 0055H (A22 value).

Adjustment

For successful measurement of ORP, ORP value in the sensor location, electrode performance and standard solution accuracy respectively play an

important role for obtaining reliable data. By setting the adjustment value, calibrates ORP value displayed on the WIL-101-ORP to read 260 mV (at 20 ) when immersing the ORP Combined Electrode Sensor in the standard solution (Quinhydrone potential difference 260 mV).

Attached Functions

Set value lock Lock 1: None of the set values can be changed.

Lock 2: Only A11, A12, A21, A22 values can be changed. Lock 3: All set values – except Adjustment value, Span sensitivity correction

value, Transmission output Zero adjustment value, Transmission output Span adjustment value – can be temporarily changed.

However, they revert to their previous value after the power is

turned off because they are not saved in the non-volatile IC memory. Outside measurement range

ORP value is outside the measurement range: If the value is less than

-1999 mV or exceeds 1999 mV, the following will be indicated.

ORP Display Setting Display

Less than -1999 mV: -1999 is flashing. Exceeding 1999 mV: 1999 is flashing. However, when ORP value is outside the measurement range, and if the unit proceeds to Adjustment Mode or Span Sensitivity Correction Mode, the

ORP Display will be unlit, and the Setting Display will flash . Power failure countermeasure

The setting data is backed up in the non-volatile IC memory.

Self-diagnosis The CPU is monitored by a watchdog timer, and if an abnormal status is

found on the CPU, the WIL-101-ORP is switched to warm-up status. Warm-up Indication For approx. 4 seconds after the power is switched ON, is indicated

in the ORP Display. Display sleep function In ORP Display Mode or Cleansing Output Mode, selects the item to be

indicated in the Setting Display.

’No indication’ ‘A11, A12, A21 or A22 value’ can be selected in [Setting

Display indication (p.27)].

If any item other than ’No indication’ is selected, and if indication time is

set, the display (no operation status) becomes unlit after the indication time

has passed.

By pressing any key, the display re-lights.

If the indication time is set to 0, the display remains lit, and this function

does not work. Auto-light function Automatically measures and controls brightness of the ORP Display,

Setting Display and action indicators.

for each A output type. Regardless of options being ordered, A output status can be read via the Status flag (A11, A12, A21, A22 output bit) in Serial communication.

A output status, when input errors occur, differs depending on the selections in [A output when input errors occur (p.20)] as follows:

• If (Disabled) is selected, the A output and A output status will be turned OFF if input errors occur.

• If (Enabled) is selected, the A output and A output

status will be maintained if input errors occur. Setting range -1999 to 1999 mV Setting accuracy Same as indication accuracy Action ON/OFF action A ON side A OFF side

However, if (Cleansing output) is selected in any of [A11, A12,

A21, A22 type (pp.21, 22)], Cleansing output will be given priority. Output ON time/ OFF time when A1/A2 output ON

If Output ON time and OFF time are set, A1 or A2 output can be turned

ON/OFF in a configured cycle when A1 or A2 output is ON.

ORP input error alarm

Detects actuator trouble. Even if ORP input error alarm time has elapsed, and if ORP input does not become higher than ORP input error alarm span, the unit assumes that actuator trouble has occurred, and writes Status flag 2 (A1, A2 ORP input error alarm output flags). In Serial communication, status can be read by reading Status flag 2 (A1, A2 ORP input error alarm output flags).

ORP input error alarm is disabled in the following cases.

• During Adjustment Mode, Span Sensitivity Correction Mode.

• When ORP input error alarm time is set to 0 seconds, or ORP input

error alarm span is set to 0 mV

Transmission Output (Option Code: TA)

Transmission output

Converting ORP value to analog signal every input sampling period, and outputs the value in current. If Transmission output high limit and low limit are set to the same value, the transmission output will be fixed at 4 mA DC.

Resolution 12000 Current 4 to 20 mA DC (Load resistance: Max 550 )

Output accuracy Within 0.3% of Transmission output span Transmission output adjustment

Fine adjustment of Transmission output is performed via Transmission

output Zero adjustment and Span adjustment. Transmission output status in Adjustment Mode, Span Sensitivity Correction Mode

Transmission output status can be selected in Adjustment Mode or Span

Sensitivity Correction Mode.

Last value HOLD: Retains and outputs the last value before Adjustment or

Span Sensitivity Correction. Set value HOLD: Outputs the value set in [Set value HOLD]. Measured value: Outputs the measured value in Adjustment Mode or Span

Sensitivity Correction Mode.
