NOTE
If the value is below -1.00 mg/l, “O.L” is displayed, regardless of the setting.
(21) Selection of below-4-mA output hold in <MEAS.> mode (Function
code “F.”)
When the function is set to on (enabled), analog output does not fall below 4 mA but is held at 4
mA. However, this setting can only be enabled in <MEAS.> mode.
The factory setting is disabled. If the setting is to be changed, perform the following key
operation.
(a) Select function code “F.”. → on
(enabled)
oFF
(disabled)
(b) Every time [>] key is pressed, on and oFF are alternately
displayed. → on ↔ oFF
(c) Select on (enabled) or oFF (disabled) → on
(d) Press [ENT] key to enter it. → on
(Flashes once.)
5.3.5 Key Operation in <PROGRAM.2> Mode
In <PROGRAM.2> mode, each time-setting in cleaning sequences and also “execution/stop” of
part of failure detecting functions indicated in Table 5.6 are performed.
Function codes “1” to “F” => Cleaning sequence operation time setting
Function codes “1.” to “F.” => Failure detecting function “execution/stop” selection
This subsection describes key operations to be performed by specifying function codes in
<PROGRAM.2> mode and displays associated with the key operations.
(1) Cleaning sequence and time setting for sand filter “One cylinder type” (Function code “4”,
“5”, “6”, and “7”)
(2) Cleaning sequence and time setting for sand filter “Two cylinder type” (Function code “3”,
“4”, “5”, “6”, “7”, “8”, and “9”)
(3) Failure detecting function “Execution/Stop” selection (Function code “4.”, “5.”)
