9.15 Status Input Function

One of "pulse/analog output fixed to 0%", "zeroing", "totalizer 1 and totalizer 2 reset", "totalizer 1 reset", or
"totalizer 2 reset" can be assigned to the status input.
For details of individual functions, refer to the respective items below.
9.15.1 Pulse/analog output fixed to 0% (0% Sig Lock)
When an input arrives across status input terminals, pulse output and analog output are fixed to 0Hz and
0mA, respectively.
Stopping an input across status input terminals cancels fixing of the output.
(1) Operating procedure
・Select "0% Sig Lock" in selecting the status input function assignment.
(See 9.2.5 Transition chart (4) [No. 2 to 5-1].)
・Set the input mode of status input. According to the settings, the following input mode will be
enabled:
"Short Active" setting: the function is activated 0.3 seconds after the condition of the circuit
between status input terminals is changed from opened to shorted.
"Open Active" setting: the function is activated 0.3 seconds after the condition of the circuit
between status input terminals is changed from shorted to opened.
(See 9.2.5 Transition chart (4) [No.2-5-2])
The function becomes available by setting the above.

9.15.2 Zero adjustment (Auto Zero)

When an input arrives across status input terminals, automatic zero is initiated to reduce offset flowrate
drift to minimum.
(For detail of the function, see "9.8 Zeroing Function".)
(1) Operating procedure
・Select "Auto Zero" in selecting the status input function assignment.
(See 9.2.5 Transition chart (4) [No. 2-5-1].)
・Set the input mode of status input. According to the settings, the following input mode will be
enabled:
"Short Active" setting: the function is activated 0.3 seconds after the condition of the circuit
between status input terminals is changed from opened to shorted.
"Open Active" setting: the function is activated 0.3 seconds after the condition of the circuit
between status input terminals is changed from shorted to opened.
(See 9.2.5 Transition chart (4) [No.2 to 5-2])
The function becomes available by setting the above.

9.15.3 Totalizer 1 and totalizer 2 reset (Reset Total 1 and 2)

The transmitter is provided with counters (Counters 1 and 2) and totalizers (Totalizers 1 and 2) which
work in synchronism with pulse output. When an input arrives across status input terminals, all these
counters － Counters 1 and 2 and Totalizers 1 and 2 － are reset to 0.
In this connection, counter 1 and totalizer 1 respond to pulse 1 output while counter 2 and totalizer 2
respond to pulse 2. (For detail of the function, see 9.10 Reset Function.)
(1) Operating procedure
・Select "Reset C/T 1･2" in selecting the status input function assignment.
(See 9.2.5 Transition chart (4) [No. 2-5-1].)
・Set the input mode of status input. According to the settings, the following input mode will be
enabled:
"Short Active" setting: the function is activated 0.3 seconds after the condition of the circuit
between status input terminals is changed from opened to shorted.
"Open Active" setting: the function is activated 0.3 seconds after the condition of the circuit
between status input terminals is changed from shorted to opened.
(See 9.2.5 Transition chart (4) [No.2 to 5-2])
The function becomes available by setting the above.
NOTE: For this function, the setting change is disabled in Write
Protect mode (refer to section 9.2).
