PAC Alcor JFTOT II Manual page 23

When JFTOT power is switched ON, the computer
performs a self-test. If the self-test passes, the
MAIN MENU is displayed. If the self-test does not
pass, then an appropriate message is displayed.
Possible reasons for failing the self-test are:
a. Test fragment in memory. If the power was
turned off during a test, any recorded test data is
still in memory as a "test fragment". A test
fragment message will appear and allow you to
print the data. Press ENTER to print the test
fragment. Once the data is printed, the "test
fragment" is deleted and the MAIN MENU is
displayed.
b. Clock stopped. The JFTOT will force a default
time 00:00:00 and date 01/01/50. The CLOCK
MENU will be displayed so the correct time and
date can be set. See section 3.2.5. When finished
the MAIN MENU is displayed (unless there is a
test fragment).
c. Thermocouple not calibrated. A message will
appear to inform the operator that the thermo-
couple is not calibrated. Press any key to remove
the message and display the MAIN MENU
(unless the clock is stopped or there is a test
fragment). A Custom test can be performed
without calibration, but a D3241 test requires
calibration.
d. Number of installed DP transducers has
changed. The JFTOT will detect if a DP transducer
and bypass valve have been added or removed. A
message will be displayed asking if the new configu-
ration is correct. If the new configuration is correct
the JFTOT will record this new configuration and
display the MAIN MENU (unless the system is not
calibrated, the clock is stopped, or there is a test
fragment in memory). If this configuration is not
correct the JFTOT will consider it a hardware
failure.
e. Hardware failures. If a hardware problem is
detected an appropriate message is displayed. This
message can not be cleared and the MAIN MENU
will not be displayed. Turn the power OFF and repair
the problem.
JFTOT II Operation Manual Rev. C
The MAIN MENU is displayed when the JFTOT is
idle, and all operations are off*:
Aeration Pump OFF
Heater power
Drive Pump
Bypass Valves OPEN
NOTE - if the drive pump is descending, it will
continue descending until it reaches the bottom.
Return to the MAIN MENU before turning power to
the JFTOT OFF. It is important that the JFTOT is
powered-off and stored in a known state. Storing the
JFTOT with the bypass valves OPEN prevents air
from accidentally entering the DP transducer(s) and
lines. It is important to maintain a liquid full DP
system.
3.2.1 Test Operation
The test operation allows an operator to setup
and run a thermal oxidation test. Two test
selections are provided, CUSTOM and D3241.
The CUSTOM test allows the operator to adjust
many of the test parameters. This provides a
means to design a custom non-ASTM thermal
oxidation test. The user adjustable parameters
are, by default, initially set to the values required
by ASTM D3241, so the CUSTOM test can be
used to run a test as specified by ASTM D3241.
The D3241 test is basically the same as the
CUSTOM test except that most of the test
parameters are fixed as specified by ASTM
D3241. To run the D3241 test, see the D3241
Manual. The following list of parameters are
fixed in the D3241 test as compared to variable
in the Custom test.
