Table 5.1 Operation Key/Display Names and Functions
Name Function
(1) Data display (indicated by red LEDs) Measured values, setting data, message, etc. are displayed.
(2) Function code display (indicated in red) A selected function code is displayed.
(3) Mode display (indicated in green; lamp
lights)
A operation mode is displayed. A lamp relevant to the current
mode is lit.
(4) Unit display (indicated in green; diffused
lighting)
One of data units is displayed. A unit for the data displayed in
the data display is lit.
(5) <Fail> display (indicated in red; diffused
lighting)
This is lit when the processor fails or a failure is detected.
(6) Operation display 1 (indicated in green;
diffused lighting)
This goes ON/OFF corresponding to turning ON/OFF of the
cell motor, pumps and air pump.
(7) Operation display 2 (indicated in green;
diffused lighting)
This goes ON/OFF corresponding to turning ON/OFF of
solenoid valves.
(8) Status display (indicated in green;
diffused lighting
Each status item of "output HOLD", "CALibration", and
"WASHing" lights, flashes, and flashes respectively when
actuated, otherwise those extinguish.
(9) Mode key This is used for selecting operation mode.
(10) Function key This is used for selecting the function code.
(11) Data set keys These are used when set data is to be changed or calibrating
operation is performed.
(12) Operation command keys-1 These are used when the cell motor, pump, or air pump are to
be turned ON/OFF.
Every time a key is pressed, the pump cell motor, or air pump
relevant to that key is turned ON/OFF.
(13) Operation command keys-2 These are used when solenoid valves are to be turned ON/
OFF.
Every time a key is pressed, the solenoid valve relevant to
that key is turned ON/OFF.
5.2 Operation Modes and Functions
Operation of the residual chlorine analyzer is determined broadly by three operation modes
(modes are classified into four types).
(1) Measuring mode (<MEAS.> mode)
(2) Maintenance mode (<MAINT.> mode)
(3) Setting mode
• Data setting/operation setting mode (<PROGRAM.1> mode)
• Cleaning sequence setting/Failure detecting function selection mode (<PROGRAM.2>
mode)
Data display items and setting items, and command items such as calibration are determined
using Function in each mode. The setting data is stored in EEPROM.
Thus, various operations are performed by specifying a mode and a function code.
Table 5.2 briefly shows each mode and function codes in that mode. For specific contents of
each function code, see subsections 5.2.1 to 5.2.4.
