6.2.55 SETUP, [LIMITS]
The ADTS 405 is preprogrammed with the manufacturer's STANDARD, CIVIL and MAX limit sets.
Different sets of additional limits can be programmed using the CONFIG mode. SETUP, [LIMITS]
allows the selection of the set of limits to be used, each set of limits is identified by an aircraft name
or component/system number.
a. Use [NEXT] or [PREV] to step through the aircraft names and when the display shows the
required name, press [SEL], then
CLEAR/QUIT .
b. Use CONFIG, [LIMITS] to program the sets of limits. Each set of limits includes:
The set of limits used at power-up (default) can be selected using CONFIG, [LIMITS], [DEFAULT
AIRCRAFT]. The default aircraft set of limits can be locked using CONFIG, [LIMITS], [LOCK AIRCRAFT]
so that an operator cannot change the limits.
If the selected set of limits result in the measured pressure values being outside the limits, the
display shows the warning message “
OUTSIDE LIMITS GO TO GROUND ” the Ps and Pt channels
should be taken to ground or to pressures within the new selected limits. This warning message is
also displayed if the pressures measured directly after power-up are outside the limits used at
power-up.
After selecting a set of limits, the altitude correction value can be changed using SETUP, ALT. The
maximum Mach limit can be changed or turned off using SETUP, MACH.
6.2.56 SETUP, HELP
This function provides help on the set-up key.
6.2.57 CONFIGURATION
1. Any parameters, changed in any mode of SETUP, return to the default settings when the
system is next switched on. The CONFIGuration mode may be used to change the default
settings so that the ADTS 405 powers-up in a specified state. Most SETUP parameters are
also available in CONFIG; other parameters are only available in CONFIGuration.
2. Some parameters, changed in set-up mode, can be locked in CONFIGuration preventing
access. For example, a system used in a servicing procedure for a specific aircraft type can
be set to power-up with a specific set of limits that must not be changed. The set-up
menus can also be locked out or access restricted preventing changes to operating
parameters.
