1. Operation
After every wiring is completed, power on the converter. LCD screen first displays startup screen , then it transitions automatically "Home screen".
When single measurement is set to display on a screen, Home screen will be skipped and Main screen will show up. See chapter 2 to know screens.

Main Screen
or
Figure 1.1
Sample image of startup screens
NOTE
It takes more than ten seconds for the startup screen to switch to Home screen after FLXA402 is powered on.
When you use SENCOM SA and connect no SENCOM SA or incompatible sensors, an error appears to indicate inappropriate setting or measurement error. To review and modify initial setup, if you need. See chapter 4.
NOTE
For several seconds after power is on, 4 mA is output. This does not imply the device has fault.
NOTE
In the beginning of the measurement, you might see the measurement displayed "----". This happens because the sensor is preparing for the measurement and not because of fault. Wait until the sensor is ready.
While the measurement is displayed "----", mA output follows the order defined in mA output settings: mA output settings > mA > mA (Configure Hold) > Last or Fixed
NOTE
When there is no touch operation for 10 minutes, the screen automatically switches to Monitor screen

Arithmetic by multiple sensors
The arithmetic is carried out by processing the corresponding value of Sensor 1-1 and Sensor 2-1. Set the same type of sensors to Sensor 1-1 and Sensor 2-1. Besides sensor type, the following must be set identical between Sensor 1-1 and Sensor 2-1.
When pH sensors are used: Sensor type When SC/ISC sensors are used: Unit, Method When DO sensors are used: Unit When the setting is inappropriate, an error occurs. While this function is being operated and an error occurs on Sensor 1-1 or Sensor 2-1, the output value is kept same as the previous one. Ratio, Passage, Rejection, Deviation, pH calb (VGB) are calculated only when the measuring object is conductivity. Differential CONDUCT, Differential RESIST, Average CONDUCT, Average RESIST are calculated when the measuring object is Conductivity-TC1 or Resistivity-TC1.
The table below shows the arithmetic equation for each parameter.

l Burn
When a failure happens, burn is output. Select one mA from "Off", "Law" or "High" to output the
failure. Read 4.7
Error settings for setting failures.
Off:
Output by the measured value.
Low:
Output is fixed to 2.2 mA
High: Output is fixed to 22.0 mA.
Burn happens only when failure is detected on the sensors you set on Process parameter slot. Sensors you did not set on Process parameter slot do not output burn even when their failure is detected.
Whenever the converter's failure is detected, it outputs burn value.
If a communication error inside of the converter is detected, the converter seeks the error location: first or second sensor module. Only when the analog sensor module you set detects an error, burn is output.
l Damping time
This is the time taken for a response to a step input change to reach 90% of the final value (attenuation time). Set this time in sec.
4.3.2 Simulate
When this function is selected, an output of the instrument will be a fixed current value set in % of the output span. The output span range is -11.25% to 112.5% (2.2 mA to 22.0 mA).
When "Simulate" is selected, regardless of hold setting, the output is always simulated value.
Host devices enables the converter to output simulated mA via MODBUS or HART communication without changing the actual configuration.
After you activate Simulate, the simulated output can remain even after the power is off. However, a simulated output via MODBUS or HART communication is deleted when the power turns off during the simulation.
mA output automatically leads to hold during device configuration. However, when Simulate is selected, each simulated value is output immediately according to respective configuration.
When mA output is simulated, Check Function occurs.
4.3.3 Configure Hold
On the Configure Hold, you can configure a preset value of mA output at Hold status.
There are two types, automatic or manual hold. Automatic hold holds mA value during the device configuration, calibration or wash.
During Setting devices, the status is always "hold", when you cannot set it to disable.
To disable hold during calibration or wash, set "Hold during calibration" to "Disabled."
Read 3.7
Hold operation (manual Hold)for further information on Hold.
l Types of value
Set mA output value for hold condition. Default is "Last", or a value measured just before hold condition.

4.4.2 Hold
When mA output is held, contact outputs are activated (S1/S2/S3: close). Assign "mA1" "mA2" "mA3" "mA4" on each hold contact output.
4.4.3 Wash
Contact output can control wash interval, while washing sensors being recognized as intervention period of the regular measuring. The Wash cycle goes as follows:
Wash time (Tw):
Sensors are being washed chemically or by machine.
Recovery time (Tr) Sensor system is being recovered.
After the recovery, the washing cycle ends to go back to the regular measuring mode.
When a contact output is set to Wash, if you use contact input, you need to set "Contact input Wash" at Contact input settings.
If a reference electrode fails to show "Input resistance too low", you can activate Wash with using contact input and resume a wash cycle.

Sensor wellness (only PH)
FLXA402 has a function for checking whether measurements are normally conducted after wash, with checking a sensor response.
The wash recovery check is performed by making use of the time to recover half the wash-cycle pH change. The half the wash-cycle pH change recovery time replaces the relaxation time with the recovery time.
Whether to conduct the wash recovery check can be set on the Error setting. Half the wash-cycle pH change refers to half the value (1/2pH) of the difference (pH) between the pH value during normal measurement of an example in Figure 4.6 and the pH value detected during wash.
If the pH value during wash is greater than 1/2pH when 1/3 tR has elapsed, the electrode is assumed to be good. If it is smaller than 1/2pH, then the electrode is assumed to be bad.
However, for applications where the pH during wash shows almost the same value as the normal pH, the difference will be approximately zero. In such a case, disable the wash recovery check.
An example of such applications is the monitoring of waste water pH. If you select water jet cleaning in such a case, the normal pH as well as the washing time pH will be around pH 7; the difference will be approximately zero, so the recovery time check will not work normally.
This function is also available for ORP only measurement.

4.4.4 Fail
A fail contact is energized when a fail is detected. When a fail is detected, the contact output is On (S1 / S2 / S3: closed, S4: open). Error is configured in 4.7 Error settings.
l Process parameter slot
Select sensors from "Sensor 1-1", "Sensor 1-2", "Sensor 1-3", "Sensor 1-4", "Sensor 2-1", "Sensor 2-2", "Sensor 2-3", "Sensor 2-4." Fail is output only by the sensors you select. Fail from FLXA402 is always valid.
NOTE
When an internal communication error occurs, a fail is output. However, the error location would not be identified whether it happened in the first or second sensor module.
l Setting
Select "Hard Fail only" or "Hard + Soft only". Hard Fail only: Contact output reacts only to Failure. Hard + Soft only: Contact reacts to alarms "Failure and Check Function", "Out of Specification",
or "Maintenance Required". To react to alarms, contact output flashes every 2 seconds, repeating excited and non-excited. When Failure happens, contact output stays On (S1/S2/S3: close, S4: open).
4.4.5 USP

When you use other than SENCOM SA (e.g. analog sensor module, Optical DO Sensor), register "1" to sensor connection number. By default, "1" is assigned on Address CH1-1 (sensor connection number 1-1). If you assign address 1 to 247 to SENCOM SAs but SENCOM SA is not connected or the communication is not established correctly, the network goes fail and the alarm occurs.
Sensor Address setting (S) allows you to assign up to 8 types of sensor addresses on Address CH (sensor connection number) 1-1, 1-2, 1-3, 1-4, 2-1, 2-2, 2-3, 2-4 . (The number before hyphen represents 1st or 2nd sensor module
i.e.1-:1st sensor module, 2-: 2nd sensor module) For instance, when a SENCOM SA is connected to 1st sensor module, the SENCOM SA address should be assigned to Address CH (sensor connection number) 1-1, 1-2, 1-3 1-4.
NOTE
FLXA402 allows only one sensor to connect to the 2nd sensor module. If you assign SENCOM SA address to one of 2-1, 2-2, 2-3, 2-4, assign 248 to the other (not assigned) three Address CH. For HART, always use Address CH (sensor connection number) 2-1.

Example of MODBUS addressing
If you want to assign SENCOM SA - MODBUS address 8 to mA2,
first assign MODBUS address 8 to Address CH1-3. Next if you want to assign Sensor 1-3 to mA2, go to "Converter menu" > mA output > mA2 > Process parameter slot, and select.

FLXA402 as slave communicates with HOST devices, via MODBUS RS-485, Bluetooth, or Ethernet (Modbus TCP/IP). Select a network system according to the hardware architecture you use. For further technical information on MODBUS, read TI 12A01F01-62EN. First of all, before Bluetooth paring with devices, you need to create Bluetooth device name with up to 12 characters. The default is serial number of the device. On each device of the network, "FLXA402- [Bluetooth device name]" is diaplayed. [Bluetooth device name] is loaded on to the system display after the FLXA402 reboots.

CAUTION
Do not cancel error settings if the cancellation may cause hazards.
NOTE
The "Impedance 1 too high/too low" and "Impedance 2 too high/too low" alarms are displayed in the Error setting. In general, for a pH sensor, "Impedance 1" represents "glass electrode," and for an ORP sensor, it means "metal electrode." "Impedance 2" represents the reference electrode in all cases.
The "Impedance 1 too high/too low" and "Impedance 2 too high/ too low" errors apply to sensors with liquid earth. Sensors with liquid earth include PH8EFP, PH8ERP, PH8EHP, OR8ERG, OR8EFG.
For sensors not equipped with liquid earth, these alarms should all be set to Off. These sensors include HA405, HA406, DPA406, DPA405, DPAS405, HF405, HA485, DPA485.
For measuring a solution with low conductivity such as pure water pH measurement, set the "Impedance 2 too high" error to Off.
NOTE
When ORP is specified as a sensor type in "Sensor setup", and when an ORP sensor, such as OR8ERG or OR8EFG, doesn't have any temperature element, set both of "Temperature too high/low" in "Error settings" to Off so that no related error is caused. Due to the open input of temperature signal, a false error may happen as if temperature goes over a high limit or a low limit.
For details of errors, refer to MODBUS technical information TI 12A01F01-62EN.

Each device on the Modbus network requires a unique Device Address/Slave ID, usually programmable for 1-247 devices. Therefore, each SENCOM SA must have different Device Address from each other. This allows devices on the network to know what data packets are relevant to them, and which are meant for other devices.
If Device Address/Slave ID 248 (invalid) is assigned, this function is disabled.
NOTE
For analog sensor module or Optical DO sensor, this function is not available.
l How to search Modbus
The next figure shows an example of Modbus search under the following condition. Connect 3 SENCOM SAs of Modbus address 1, 3, 4 On the converter, address "1" is assigned to Address CH (sensor connection number)1-1, "4" to 1-2, "12" to 1-3, "248 (invalid)" to 1-3. (1) Select a sensor module. (in the sample, Sensor 1 is selected.) (2) Modbus search is displayed. You can configure the address to start the search. After the configuration and confirmation, tap "Start" to start the search Modbus. Ch number (a number after "-") of Address CH (sensor connection number) and Modbus address (1 to 247) are displayed.
<Example> Modbus address assigned to Target sensor 1-2 is displayed on Sensor1 Ch2. If the connection fails although the Modbus address is assigned valid (1 to 247), alert shows up next to Ch number. In the example, Modbus address 1, 4, are assigned to Target sensor 1-1, 1-2 respectively. This means the communication is established already. However, although Modbus address 12 is assigned to 1-3, shows up because SENCOM SA of Modbus address 12 cannot be found. To start the search from the address 1, tap "Start". (3) "Searching" and the address are displayed. If you tap "Cancel" while the address is still on search, the Modbus search stops and moves to the screen for selecting sensor module. (4) When Modbus address is found, a dialog box appears. If you keep on searching, tap "YES", then you will move to the screen for searching the Modbus address. Tap "Cancel" to stop the searching and move to the first screen for selecting sensor module. (5) After you complete searching all valid Modbus address (1 to 247), a dialog box appears to notify no more address is found.

5.3 Bluetooth pairing
FLXA402 use Bluetooth communication with host PC devices for the maintenance.
At first, Starting Bluetooth needs to pair Bluetooth with host devices you want to use and verify the communication.
If the number of paired devices exceeds the maximum number of 10, the paired devices are to be deleted in their chronological order.
l How to pair Bluetooth with host devices
1. Prepare host devices you want to communicate with FLXA402.
On FLXA402, go to Bluetooth pairing, and tap [Next].
(Read user's manual of the host devices to know how to start the Bluetooth pairing on the device side, if you need.)
2. On FLXA402 screen, "Searching" starts flashing.
Turn Bluetooth on the host device.
Find FLXA402 Bluetooth name on host device. You can Also, see the name of FLXA402 Bluetooth on Converter menu > Detail (3.1). If you need, change the setting on Modbus setting (4.6.1)
3. Once the host device finds FLXA402 Bluetooth, automatically FLXA402 goes to the last page of Bluetooth pairing screen.
On the screen, you find "Pass key." Confirm "Pass key" is same as the one the host device displays. After the pass key is confirmed, tap "Pairing".
If you don't see "Pairing" key for 60 seconds, or if you tap "Cancel" instead, you will return to "Others".
If you want to exit the Bluetooth pairing, press "<" or "Home".

5.4 Password
Protect setting, calibration and others with password. Read 1.3 Passwordon how to establish password.
Figure 5.19
Password
Both "Commissioning" and "Execute" boxes are blank by factory default. If you leave the boxes blank, password is invalid to secure operation. You can create a password with up to 12 characters.
CAUTION
Keep passwords safe.
After you create a password, you will be prompted to enter the password for each designated operation such as setting or calibration. If the password is not verified, "Wrong password" appears on the screen.
If you enter correct password, you will see "Enter operator ID."
Logbook database is created by saving Operator ID to identify those who entered the system. However, you can skip and do without entering the Operator ID. Operator ID is created by 4 characters at maximum.

n FLXA402 periodic maintenance
The FLXA402 requires very little periodic maintenance, except to make sure the front window is kept clean in order to permit a clear view of the display and allow proper operation of the touchscreen.
If the window becomes soiled, clean it using a soft damp cloth or soft tissue. To deal with more stubborn stains, a neutral detergent may be used.
When you must open the front cover and/or glands, make sure that the seals are clean and correctly fitted when the unit is re-assembled in order to maintain the housing's weatherproof integrity against water and water vapor.
The pH measurement uses high impedance sensors and may otherwise be prone to problems caused by exposure of the circuitry to condensation.
CAUTION
Never use harsh chemicals or solvents. If the window does become heavily stained or scratched, parts replacement might be required. Contact Yokogawa service center.
l Battery
The FLXA402 has a logbook feature that uses a clock to provide the timings. The instrument contains a lithium cell (battery) to continue the clock function while the power is turned off. Although the cell has an expected working life of 10 years, this is not guaranteed. When this cell needs replacing, contact your nearest Yokogawa service center.
n Periodic maintenance of sensors
