PerkinElmer Photovac MicroFID, User Manual

Page: 125 / 170

Troubleshooting
Action: At low temperatures, water vapor, a by­
product of the hydrogen flame, may
condense at the exhaust port. At sub zero
temperatures the water vapor will freeze
and obstruct the exhaust port. If the exhaust
port becomes obstructed, pump operation
will be inhibited. Flame out may also
result. Operate MicroFID within the
operating temperature range 5° to 40°C
(41° to 104°F ).
Action: The flame arrestor has become plugged.
Contact the Service Department.
Cause: Hydrogen supply lines are full of air.
Action: If MicroFID has not been used for some
time, it is possible that the hydrogen supply
lines contain air. Fill the hydrogen cylinder
and then open the hydrogen shut­off valve.
Allow the hydrogen to purge the system for
about 5 minutes and then turn MicroFID on
and start the flame.
Cause: Hydrogen supply lines are blocked.
Action: Contact the Service Department.
Problem: Liquid has been aspirated.
Cause: MicroFID has been exposed to a solvent that can
pass through the Teflon/Polypropylene filter.
Action: Contact the Service Department.
Problem: In Method 21 operation, the next event is not
displayed after you have recorded background and sample
readings for the current event.
Cause: Duplicate events are present in the datalogger.
Action: Print the contents of the datalogger to
ensure the duplicate events are unused. Use
the “D elete” option under the EVENT key
to remove the duplicate event from the
datalogger.
