NonLatch
The BAS was setup as
"installed" at the MP and the
Comm 3 LLID lost
communications with the BAS
for 15 contiguous minutes after
it had been established. Refer
to Section on Setpoint
Arbitration to determine how
setpoints and operating modes
may be effected by the comm
loss. The chiller follows the
value of the Tracer Default Run
Command which can be
previously written by Tracer
and stored nonvolatilely by the
MP (either use local or
shutdown)

The following Diagnostic Table
contains all diagnostics possible
arranged alphabetically by the name
assigned to each diagnostic. Not all
diagnostics are available unless
TechView is installed.
Legend to Diagnostics Table
Hex Code:
3-digit code used to
uniquely identify diagnostics.
Diagnostic Name:
Name of the
diagnostic as it appears at DynaView
and/or TechView displays.
Severity:
Defines the action of the
above effect.
Immediate means an
instantaneous shutdown of the
affected portion.
Normal means
routine or friendly shutdown of the
affected portion.
Special Mode
means a particular mode of
operation is invoked, but without
shutdown, and
Info means an
Informational Note or Warning is
generated.
Persistence:
Defines whether or not
the diagnostic and its effects are to
be manually reset (Latched), or can
be either manually or automatically
reset (Nonlatched).
Criteria:
Quantitatively defines the
criteria used in generating the
diagnostic and, if nonlatching, the
criteria for auto reset.
Reset Level:
Defines the lowest level
of manual diagnostic reset
command which can clear the
diagnostic. The manual diagnostic
reset levels in decreasing order of
priority are: Local, Remote and Info.
For example, a diagnostic that has a
reset level of Remote, can be reset
by either a remote diagnostic reset
command or by a local diagnostic
reset command, but not by the
lower priority Info Reset command.
