Treatment
The system
alarm is activated
when there is a
serious hardware
problem that
prevents
performing
reliable
measurements.
By clicking alarm
button will be
displayed with
the fields that
cause the alarm
colored in red.
Please note the
control will not
update when
open, it is only a
snapshot of
alarms from the
moment the
button to view the
alarms was
pressed.
Bath Temperature
The bath temperature
differs more than 0.2 °C
from the setting.
Check the temperature of the bath
on
HW Status
tab. Restart the test
gas generator.
If it doesn’t help, contact the
service.
Evaporator
Temperature
The evaporator
temperature differs
more than 10 °C from
the setting.
Check the temperature of the
evaporator on
HW Status
tab.
Restart the test gas generator.
If it doesn’t help, contact the
service.
Probe Temperature
The probe temperature
differs more that 10 °C
or probe tube
temperature differs
more than 30 °C from
the setting.
Check the temperature of the probe
(temperature controller is attach to
the probe). If temperature is OK,
check the alarm wires. Otherwise,
contact the service.
Instrument air
Pressure
Instrument air pressure
is too low.
Check that instrument air input
gauge shows proper pressure
values. If not, find out why
instrument air supply is down in the
plant. If there is sufficient pressure
reading (min 6 bars), then open the
flowmeter fully and adjust all
pressures
according
to
the
recommended
values
and
recalibrate the system
.
Lamp Temperature
The mercury lamp
temperature differs
more than 5 °C from the
setting.
Check the temperature of the lamp
on
HW Status
tab. Restart the
analyzer.
If it doesn’t help, contact the
service.
Oven Temperature
The oven temperature
differs more than 50 °C
from the setting.
Check the temperature of the oven
on
HW Status
tab. Restart the
analyzer.
If it doesn’t help, contact the
service.
Cell Temperature
The sample cell
temperature differs
more than 10 °C from
the setting.
Check the temperature of the cell
on
HW Status
tab. Restart the
analyzer.
If it doesn’t help, contact the
service.
Line Temperature
The sample line
temperature differs
more than 10 °C from
the setting.
Check the temperature of the line
on
HW Status
tab. Restart the
analyzer.
If it doesn’t help, contact the
service.
Cell Pressure
Cell pressure is more
than 200 millibars.
Check the temperature of the cell
on
HW Status
tab. Check that there
are no blockages in pipes and that
