Cell application
failed.
Gas sensor(s) not able to
detect gas concentration due
to technical failure.
Switch off heating to ventilate instrument. Switch
off-on gas control module using ON/OFF switch.
Wait for sensors to level for at least 10 min. Use
mode key to switch to Manual Mode to display the
actual CO
2
and O
2
gas concentration at ambient
conditions: CO
2
(~0.2%), O
2
(~20.9%) (depending
on ambient atmosphere, e.g. humidity).
Use the ‘Mode’ key to switch to ‘CO2’ and switch
ON the valve by pressing I/O key, monitor if the
gas concentration value changes. Switch OFF
valve for CO
2
by pressing the ‘I/O’ key. Press the
‘Mode’ key to switch to ‘O2’ and switch ON valve
by pressing the ‘I/O’ key, monitor if the gas
concentration value changes. Switch OFF valve
for O
2
by pressing the ‘I/O’ key.
If the gas concentration value does not change,
contact your local Tecan Expertline.
Error message
“CO2 OUT OF
RANGE”
Gas pressure/flow of CO2
too high in Manual Mode.
‘Actual’ (current) gas
concentration has exceeded
15 % (vol.).
Valves will close automatically to stop the gas
flow. Reduce CO2 pressure with pressure
reduction valve on gas cylinder or laboratory gas
handling system. Wait until ‘actual’ (current) gas
concentration is below 15 % (vol.) (e.g. open
plate carrier compartment to speed the reduction
of CO2 value) before resuming.
Data cable not connected to
the gas control module
and/or Infinite 200 PRO.
Verify that data cable is connected to the gas
control module and/or Infinite 200 PRO
Error message
“O2 OUT OF
RANGE”
O2 sensor detects a value
higher than 21%.
Check that the correct gas is used.
If the problem persists, contact your local Tecan
Expertline.
Error message
“O2 NO
SENSOR”
Data cable not connected to
the gas control module
and/or Infinite 200 PRO.
Verify that data cable is connected to the Gas
Control Module and/or Infinite 200 PRO.
Instrument with ‘CO2’
configuration – no O2 sensor
installed.
For instruments with ‘CO2’ configuration,
In Manual Mode ‘NO SENSOR’ will appear on
display after ‘O2’.
(O2 Mode and Dual Mode menus are unavailable
and not displayed.
Acoustic signal
Display is
blinking
•
Target concentration is not
reached after 20 min upon
initial activation of a mode.
•
‘Actual’ (current) value
deviates from target value
for more than 10 minutes
during operation.
Gas cylinder is empty or no gas supply available.
Gas supply low on pressure. Verify that sufficient
gas is available. Check gauges on the pressure
reduction valve. Check tubes. Check for leaks.
Check that the shut-off valve of the pressure
reduction valve is open.
When target value is reached, the acoustic signal
and blinking display will stop.
