Terminal block 3 <TN3>
Between 1 to 4 : For internal connection. Must
not be wired. (Must not be used
as junction terminal.)
Between 5 – 6 : Remote hold input. No hold
when open. Output hold when
short-circuited.
Between 7 – 8 : Average value reset input.
Short-circuiting the contact input
(for at 1.5 sec or more) resets O
2
average and O
2
correction
average simultaneously.
Opening it restarts the average
value.
Between 9 – 10 : Automatic calibration remote
start input. Open input after
strapping for at least 1.5 seconds
starts the automatic calibration
whether automatic calibration
setting is ON or OFF.
Between 11 – 12 : Conductive when analyzer unit
error is producted. Normally
open.
Between 13 – 14 : CH4 range identification signal
Between 15 – 16 : CH3 range identification signal
Between 17– 18 : CH2 range identification signal
Between 19– 20 : CH1 range identification signal
Note) Range identification
signal is conductive at
Low range or open at
High range.
In case of 1-range
system, the signal
remains open.
