Q
Contact output types
The following contact output types are available.
z
"non"; No output
This setting disables the contact output.
z
Concentration alarm output
When a measured value is continuously higher than a set value for alarm triggering during
delay time, an alarm is output (driving a relay) after the delay time, and an alarm is raised.
When the measured value becomes lower than the setting, the output immediately turns
OFF, canceling the alarm. (The above explanation is applicable to the upper limit
operation.) For the lower limit operation, the process is reversed.
The settings include:
・
"HorL": Control method setting
"Hi" (the action occurs when the upper limit is exceeded)/"Lo" (the action occurs when
the lower limit is exceeded).
・
"SEt": Controlled value setting: 0 to 20000 (mg/L)
・
"dt": Delay time setting: 0 to 600 (s)
z
"HoLd": HOLD output
When a measured value is in the HOLD state, an alarm is output after delay time. When
the hold mode is canceled, the output is immediately turned OFF.
・
"dt": Delay time setting: 0 to 600 (s)
z
"CLn"; Cleaning-in-progress output
This is the contact output during cleaning.
The settings include:
・
CLn.t: cleaning output type settings:
"CLn": A contact is output in the HOLD state during cleaning and after cleaning.
"trg": A contact is output for 5 s within 2 s after the end of cleaning.
Tip
"CLn": If cleaning output is set to "trg", entering this output to the contact input of a same series of
HORIBA Advanced Techno converters makes it possible to perform the chain motions of cleaning (to
perform cleaning operation at different time shifted by each converter). For example, if this motion is
used, there is no need to take into consideration a decrease in the pressure of water sources or air
sources for water cleaning or air cleaning.
