Execute a function when the digital input changes from “open” to “closed.”
• Status input
Execute and continue executing a function while the digital input is closed.
Setup menu path:
[HART] “Detailed setup>>I/O condition>>Digital input>>DI-1 or DI-2”
[YH8000] “Configuration>>I/O>>Digital Input>>DI-1 or DI-2”

Functions that can be executed
The following shows the functions that can be executed.
Function Name Action Input Method
External Alarm Generates the “External Alarm” warning. Status
Zero Calibration Executes automatic zero calibration. Edge
Span Calibration Executes automatic span calibration. Edge
Zero + Span
Calibration
Continuously executes automatic zero calibration and
automatic span calibration.
Edge
Offline Validation 1 Executes automatic offline validation 1. Edge
Offline Validation 2 Executes automatic offline validation 2. Edge
Offline Validation 1 + 2 Continuously executes automatic offline validation 1 and 2. Edge
Online Validation 1 Executes automatic online validation 1. Edge
Online Validation 2 Executes automatic online validation 2. Edge
Stream 1 Switches the valve to stream 1. Status
Stream 2 Switches the valve to stream 2. Status
Stream 3 Switches the valve to stream 3. Status
Note: The items of the above selection options that have been disabled by the “Valve usage setting” are not displayed. For details, see
“6.8.2 Valve Usage Setting”.
l
Filter time
A cutoff time can be set to prevent wrong operation due to chattering. A digital input change within
the specified time will be ignored.
6.8 Valve Stream Settings
This section describes the procedure to automatically control multiple process gas streams
according to the TDLS8000 valve control output (SV terminal). Up to three streams can be
switched.
6.8.1 Definitions of Stream Numbers
Implement the valve operation of the TDLS8000 using stream numbers defined for the statuses
of the two valves connected to the valve control outputs (SV-1 and SV-2). Do not perform valve
operation independently but specify stream numbers (independent operation is possible only
when performing a loop check).
The following shows the stream numbers to define for the TDLS8000 and the corresponding
status of each valve.
Stream No. Valve 1 (SV-1) Status Valve 2 (SV-2) Status
Stream 1 OFF OFF
Stream 2 ON OFF
Stream 3 ON ON
The process gases can be switched as shown in Figure 6.1 by switching the streams.
