2-21. Alarms Recall Routine.
This routine is performed to identify the faulty condition(s) that caused the ALARMS MAJOR or ALARMS
MINOR indicator to light. This routine is also used to turn off the ALARMS MINOR indicator if it was
lit at power turn on or when a system mode change was performed. When this routine is performed,
diagnostic information is displayed under one or more of the headings described in a below. The diagnostic
information that can appear in a message display is described in b below. The step-by-step procedures
for the routine are in c below.
a. Headings. In each message display, a heading is displayed on line 1. There are six different headings
that can appear in a routine. As described below, there are three TSSP headings that are displayed
in all models. There are three CESE headings that are only displayed in V3 and V4 models.
(1) TSSP MAJOR NEW Heading (A// mode/s). The TSSP diagnostic information for the
are detected by the TD-1337(V)~G and cause the ALARMS MAJOR indicator to light are listed
heading. The diagnostic information only appears under this heading the first time that the fault is
If the routine is repeated, and the fault still exists, the information is now displayed under
MAJOR OLD heading.
Examples of the TSSP MAJOR NEW and CESE MAJOR NEW
headings are shown in b below.
(2) TSSP MAJOR OLD Heading (All rnodels,). Each time this routine is repeated, and a specific
fault still exists, the information for the fault is displayed under this heading. If the fault goes away (no
longer detected), the ALARMS MAJOR indicator goes off and the ALARMS MINOR indicator lights. The
next time this routine is performed, the diagnostic information will be displayed under the TSSP MINOR
(3) TSSP MINOR Heading (All rnodels), A fault that was detected and is no longer detected is
only displayed under this heading during the performance of one routine. All lines of diagnostic information
displayed under this heading are erased each time a routine is performed. Therefore, if a line of diagnostic
information does appear under this heading in a repeated routine, this indicates that the same detected
fault reoccurred and went away since it was last displayed in the preceding routine.
(4) CESE MAJOR NEW Heading (V3 and V4 models). A TD-1337(V)/G monitors up to 56 CESE
status points. A fault or no-fault condition is reported by the equipment connected to each status point.
When a faulty condition is indicated at a status point input, the ALARM MAJOR indicator lights and information
for that status point is displayed under this heading.
(5) CESE MAJOR OLD Heading (V3 and V4 rnodels). CESE status point information is displayed
under the same conditions as described for TSSP MAJOR OLD above.
(6) CESE MINOR Heading (V3 and V4 models). CESE status point information is displayed under
the same conditions as described for TSSP MINOR above.
