Table 4-4. List Of Warning Codes - Will Burt Night Scan Chief Installation, Operation & Maintenance Manual

Warning Codes
Warning codes are presented on the LED eight-digit alphanumeric display. The codes are a combination
of numbers that identify both the general location of the warning, and the type of warning. The first of two
numbers is a single digit number indicating which board. The second number is a two-digit number
indicating the warning. Warning codes differ from Fault codes in that they do not require clearing. If the
condition causing the warning goes away, so does the warning. At that point, normal operation continues.
The codes are as follows:
