Enter the site password (the password is case sensitive). Next, hold the CTRL key down and
type “V” then enter the 5 digit target pressure from the portable pressure standard (Example
30.235) and press <enter>. The automatic calibration routine will make any required
adjustments to the pressure sensor parameters and the DCP will report “calibration
complete”. At the end of the routine, press the “esc” key to return to the main configuration
menu.
13.
Verify that the pressure sensors are calibrated by repeating step 10. If the sensors still differ
from each other or the standard by more than .02 in Hg. first, repeat step 12.
14.
If the sensors cannot be adjusted to within spec, then the sensors are faulty and the DCP
needs to be returned to Belfort for Factory service.
Follow the Belfort AWOS System
Component Failure Instructions in Section 5.10.
15.
Type “c” and enter the new date of calibration, then type “CR”.
16.
Press the “Esc” key. This will cause the data to be saved in the EEPROM.
17.
Exit ACBSTXCOM by typing “x” then press <enter>.
18.
Reattach the DCP to the tower with the 4 screws removed in step 11 above.
19.
Disconnect the RS232 cable from the notebook computer and reconnect the RS232 data
communication cable to the visibility sensor (if present). Apply Dow Corning #4 liberally
to the connection to protect against moisture. .
20.
Remove and reapply power to the DCP to restore normal operation.
21.
If additional maintenance tasks are to be performed, skip to next maintenance task. If
maintenance tasks are complete, toggle the “ALERT MESSAGE” switch 4 times to return
the unit to service.
22.
Observe system output and verify that the system is reporting data as expected.
23.
Switch the DC circuit breaker back on if battery backup is present.
24. Untie the rope and SLOWLY erect the tower to the vertical position and secure it by
installing and tighten-up (DO NOT OVER TIGHTEN) the three (3) tower-securing bolts.
NOTE: Be careful to avoid pinching the wires on the inside of the hinged Tower Section
when raising the tower.
24.
If all maintenance tasks are complete, issue another NOTAM advising users that
“
maintenance activities were completed, system has been returned to normal
operation
.” The expiration date and time of this NOTAM should coincide with the same
expiration date and time of the previous advisory NOTAM that was issued to put the system
in the maintenance mode. Verify that this NOTAM advisory is correctly displayed on the
operator screen. Refer to the
"Belfort AWOS Operator Manual"
for instructions on how to
enter and delete NOTAMs
