Error Function
Instrument error
(Contact output "1" fixed)
Outputs when one of the following alarms occurs: "conversion unit failure,"
"output wiring error," "optical unit error," or "internal oxygen meter error".
Instrument error
(Contact output "2" fixed)
Output when one of the following alarms occurs: "zero calibration alarm," "span
calibration alarm," "calibration stability alarm," or "auto calibration alarm.
Auto calibration mode
(Contact output "3" fixed)
Output when auto-calibration is running. When the hold setting is ON, outputs
until the replacement time after calibration is completed. When the hold setting
is OFF, the output is released when the replacement time after calibration is
executed.
Auto validation mode Output when automatic validation is running. If the hold setting is ON, outputs
until the replacement time after validation is completed. If the hold setting is
OFF, the output is released when the replacement time after the validation is
executed.
Zero calibration
(Contact output "4" fixed)
Output during zero point calibration.
Ch1 span calibration (*1) Output during Ch1 span point calibration; must be assigned if Ch1 is subject to
automatic calibration or automatic validation.
Chx span calibration (*1) Ch x Output during span point calibration; must be assigned if Ch x is subject
to automatic calibration or automatic validation; if Ch x is an external oxygen
meter, the output is used as a calibration instruction to the external oxygen
meter during automatic calibration. (x is 2 to 5)
Chx range identification Used to identify the range of Ch x. Outputs when the range is Range 1, and
cancels when the range is Range 2. Outputs when the range is Range 1, and
cancels when the range is Range 2. When the component of Ch is an O
2
-
correction value, O
2
-correction average value, or average value, the output
is not output. During hold, the output maintains the status before hold even
if range changeover occurs. This function is also used as a remote range
answerback function. (x is 1 to 5)
Blowback Output when blowback is running. Must be assigned when using the blowback
function.
Alarm x Outputs when the conditions for alarm x contact operation are met. The
conditions are as follows. (x is 1 to 6)
H-Limit/HH-Limit: When the measured value exceeds Range1 H-Limit/
Range2 H-Limit
L-Limit/LL-Limit: When the measured value is below Range1 L-Limit/
Range2 L-Limit
H-Limit or L-Limit: When the measured value exceeds Range1 H-Limit/
Range2 H-Limit, or when the measured value is below
Range1 L-Limit/Range2L-Limit
Peak count alarm Output during peak count alarms.
Sample switchover Used to switch sample gases during calibration (automatic, auto zero, manual)
or validation. When using automatic/auto zero calibration or automatic
validation, be sure to assign this.
Measuring Output
During Calibration or Validation Output cancel (Analyzer) /
Output (Sampling system)
Maintenance mode Output during maintenance, calibration (automatic, auto zero, manual),
validation, and blowback.
Power status Always output when power is ON.
System validation During automatic validation, if the gas flow channel setting is set to "sampling
system", be sure to assign this function.
Measuring Output cancel
During Calibration Output
System calibration Used when the gas flow channel is set to "sampling system" during calibration
(manual calibration/automatic calibration/auto zero calibration), so be sure to
assign this function.
Measuring Output cancel
During Calibration Output
*1: If you use a mixed gas containing multiple components as the calibration gas, assign it to the same contact point.
