IM 11G02N01-01E
Terminal 4 <TN4>
Between 1–2: Peak count alarm contact output
It is conductive when peak count
exceeds the setting time. It
remains open below the setting
time. For setting and operation,
refer to “Item 6.6 Peak alarm
setting”.
Between 3–4: Contact output of auto calibration
status
When the auto calibration is
carried out and remote hold is
ON, it is conductive. Remains
open otherwise.
Between 5–6: Pump ON/OFF contact output
Used when turning ON/OFF the
pump. It is open during auto and
manual calibration status and
conductive during measurement.
Between 7–8: Calibration error contact output
It is conductive when an error
occurs during zero calibration or
span calibration. It is normally
open.
Between 9–10: It is conductive when an error
occurs to the analyzer unit. It is
normally open.
Between 11–20: For internal connection, wiring is
not allowed. (Do not use it as
junction terminal).
