l
Meas. value during auto wash/cal.
During automatic wash or automatic calibration on a turbidimeter/non-reagent type free
chlorine meter/residual chlorine meter, this function allows you to select whether to hold current
measurement readings on screen. This is a setup of measurement readings and does not affect
the analog output.
4.5.4 SV displayed setting
Place names on each solenoid valve to display for manual operation. Naming according to
applications of the solenoid valve is recommended when using auto wash/auto calibration. For
applications of each solenoid valve, refer to user’s manual of each sensor. Note that FC800D
does not support this parameter.
4.6 Advanced settings
Advanced settings configure overall network, including MODBUS between the converter and
Host devices, MODBUS between the converter and Sensorss, Ethernet.
4.6.1 MODBUS setting
Configure MODBUS setting between HOST and the converter, the converter and Sensors.
n
Converter - Sensors
l
Sensor Address setting (S)
Normally, you don’t need to setup this parameter.
To establish communication between the converter and Sensors, register MODBUS address 1 to
247 of Sensors on the converter. 248 is for unused connection.
Use Search MODBUS if Sensors sensor address is not found. See Chapter 5.
NOTE
When you use analog sensor module, register MODBUS address “1” to sensor connection
number. If a communication error with the sensor is detected, a setting error occurs for the
function that was set up to use the sensor.
Sensor Address setting (S) allows you to assign up to 3 types of sensor addresses on Address
CH (sensor connection number) 1-1, 2-1, 2-2.
(The number before hyphen represents 1st or 2nd sensor module
i.e.1-:1st sensor module, 2-: 2nd sensor module)
For instance, when Sensor is connected to 1st sensor module, the Sensors address should be
assigned to Address CH (sensor connection number) 1-1. Don’t use the connection number 2-2.
Sensors assigned to the conncection number (MODBUS address except for 248) are sensor 1-1,
2-1, 2-2, that can be selected by each function.
<Example of MODBUS addressing>
If you want to assign Sensors - MODBUS address 8 to mA2,
first assign MODBUS address 8 to Address CH1-1. Next if you want to assign Sensor 1-1 to
mA2, go to “Converter menu” > mA output > mA2 > Process parameter slot, and select.
