If no leaks are found, apply AC power to the instrument as follows:
1 Establish airflow through the air dryer, but do not connect the air output to the test station. Allow the
air to purge for 3 to 5 minutes.
2 Connect the air supply to the test station.
3 Unlock the transducer and motor.
4 Plug the power cable from the lower power supply module into the wall outlet.
5 Turn the power switch on the lower power supply module to the On (|) position.
6 Verify that the air pressure to the motor, transducer, and oven are correct.
NOTE : To verify the proper pressure setting for the FCO ( FCO Heater Air ), the FCO must be turned on.
If the pressure is too low, the FCO turns off within a few seconds of being turned on, and the system
displays a “low pressure” error message.
Internal Filter Inspection
There are also internal filters inside the test station that should be inspected and serviced on an
approximately six month to a year basis. Only qualified service personal should perform this maintenance.
Air Dryer Inspection
Inspect and service the air dryer according to its manual. The two external filter cartridges mounted with
the air dryer can be checked and changed. Make sure the moisture indicator is green. If it turns red,
disconnect the air line, drain the filter bowls, and change the filter cartridges. Make sure the air dryer is set
to 2 .
Power Supply Maintenance
The only maintenance procedure that you can perform for the power supply units is to use a vacuum to
remove dust and debris from the fans on the rear of the units. Call TA Instruments if any other service is
required.
LN2 and FCO Maintenance
There is a filter (P/N 613.02001) associated in the LN2 Controller hose that connects into the input of the
controller. This filter removes any particle contaminants that may be introduced from the LN2 supply
source. Unless there is a slow filling problem that could be attributed to a blocked or restricted inlet, it is
usually not necessary to perform any periodic service on this filter, but periodic inspection is recom -
mended.
To maintain LN2 Controller transfer line effectiveness, the LN2 controller should be run at cryogenic tem
-
peratures for at least one hour per month to ensure optimal performance. This maintains the level of vac -
uum in the transfer line which prevents the N2 gas from absorbing heat. Failure to do so will most likely
result in the FCO losing its capacity to operate at the lower temperature limit.
Call TA Instruments if service is required.
