Connecting the Laptop to CH530
Once the software is downloaded to the
laptop, the laptop can be connected to
any CH530 main processor to monitor
current conditions, view historical data,
or change settings. To connect the lap-
top:
1 - Connect, using a RS-232 cable, to
the laptop and the CH530 main proces-
sor serial ports.
Note: The RS-232 serial port on the
CH530 is located under the slide door on
the bottom of the CH530 interface panel
(main processor).
2 - Double click on the TechView icon on
the laptop to start the program.
Diagnostics
The following Diagnostic Table contains
all diagnostics possible arranged alpha-
numerically by the three-digit code as-
signed to each diagnostic. Not all data
is available unless TechView is installed.
Legend to Diagnostics Table
Hex Code: 3-digit code used to uniquely
identify diagnostics.
Diagnostic Name: Name of Diagnostic
as it appears at DynaView and/or Tech-
View displays.
Target: Defines whether the entire Chill-
er, the Circuit or the Compressor is af-
fected by this diagnostic. None implies
that there is no direct effect to the chiller
operation.
Severity: Defines the action of the
above effect. Immediate means an in-
stantaneous shutdown of the affected
portion. Normal means routine or friend-
ly shutdown of the affected portion.
Special Mode means a particular mode
of operation is invoked, but without shut-
down, 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 ei-
ther manually or automatically reset
(Nonlatched).
Active Modes [Inactive Modes]: States
the modes or periods of operation that
the diagnostic is active and, as neces-
sary, those modes or periods that it is
specifically not active as an exception
to the active modes. The inactive modes
are enclosed in brackets [ ].
Criteria: Quantitatively defines the cri-
teria 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 order
of priority are: Local, Remote and Info.
For example, a diagnostic that has a re-
set level of Remote, can be reset by ei-
ther a remote diagnostic reset command
or by a local diagnostic reset command,
but not by the lower priority Info Reset
command.
The following Diagnostic Table contains
all diagnostics possible arranged alpha-
betically by the name assigned to each
diagnostic. Not all diagnostics are avail-
able unless TechView is installed.

Diagnostic Name: Name of the diagnos-
tic as it appears at DynaView and/or

Severity: Defines the action of the

portion. Normal means routine or friend-
ly shutdown of the affected portion. Spe-
cial Mode means a particular mode of
operation is invoked, but without shut-

Note or Warning is generated.
Persistence: Defines whether or not the
diagnostic and its effects are to be man-
ually reset (Latched), or can be either
manually or automatically reset (Non-
latched).
Criteria: Quantitatively defines the cri-
teria 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 di-
agnostic reset levels in decreasing order
of priority are: Local, Remote and Info.
For example, a diagnostic that has a re-
set level of Remote, can be reset by ei-
ther a remote diagnostic reset command
or by a local diagnostic reset command,
but not by the lower priority Info Reset
command.
