Alarm display Alarm contents Probable causes
Box Temp. Warning It is reported when the temperature
in the receiver unit and the trans-
mitter unit exceeds the temperature
for normal operation.
• The unit is used at an installation loca-
tion exceeding the set range.
• The unit is used in an environment
where gas temperature is beyond the
specification.
• Insufficient air purge causes rise in
temperature.
• The distance between the Receiver /
Transmitter unit and the stack is not
maintained sufficiently.
Low Air Purge It is reported when purge pressure
lower than the value set as alarms
on the “Analog Input” screen. • Air purge pressure is lower than alarm
setting or the analyzer is not purged.
• AI terminal is not connected to the ex-
ternal input device when the air purge
pressure is set to channel setting on the
“Analog Input” screen.
Over H-Limit 1 It is reported when “Analog Output
/ Alarm Record” is set to “Over
H-Limit 1” or “Over H/L Limit 1”
on the “Alarm Setting” screen, and
the measured value exceeds the
limit alarm of Range 1. • Concentration beyond the Range 1 limit
is measured.
• The actual path length is longer than the
measured path length set at the “Param-
eter Setting” screen.
• The actual temperature is lower than the
temperature (fixed value) set at the
“Analog Input” screen.
Under L-Limit 1 It is reported when “Analog Output
/ Alarm Record” is set to “Under
L-Limit 1” or “Over H/L Limit 1”
on the “Alarm Setting” screen, and
the measured value is less than the
limit alarm of Range 1. • Concentration less than the Range 1
limit is measured.
• The actual path length is longer than the
measured path length set at the “Param-
eter Setting” screen.
• The actual temperature is lower than the
temperature (fixed value) set at the
“Analog Input” screen.
Over H-Limit 2 It is reported when “Analog Output
/ Alarm Record” is set to “Over
L-Limit 2” or “Over H/L Limit 2”
on the “Alarm Setting” screen, and
the measured value exceeds the
limit alarm of Range 2. • Concentration beyond the Range 2 limit
is measured.
• The actual path length is longer than the
measured path length set at the “Param-
eter Setting” screen.
• The actual temperature is lower than the
temperature (fixed value) set at the
“Analog Input” screen.
Under L-Limit 2 It is reported when “Analog Output
/ Alarm Record” is set to “Under
L-Limit 2” or “Over H/L Limit 2”
on the “Alarm Setting” screen, and
the measured value is less than the
limit alarm of Range 2. • Concentration beyond the Range 2 limit
is measured.
• The actual path length is longer than the
measured path length set at the “Param-
eter Setting” screen.
• The actual temperature is lower than the
temperature (fixed value) set at the
“Analog Input” screen.
