Sanyo Chiller Type
On POR the Gateway shall determine from the Sanyo control its Chiller
Type (16DJ, 16NK, 16TJ or 16LJ). Once the type has been determined,
the uploaded Status Tables (STATUS and OPERSTAT) will contain only
data that is applicable to the type and the Table names will be changed to
indicate the determined chiller type, i.e.16DJSTAT and 16DJOPER. If the
Gateway Tables are uploaded before the Gateway is connected to the
Sanyo controller, then the default Tables will be read which contain all
data. If this should happen the controller should be deleted and reuploaded after Gateway/Controller communication has been established.
Status and Maintenance Tables
There are two Status Display Tables and four Maintenance Tables.
Status:
1. Status Table which shows Sanyo Chiller sensor analog and discrete
values as well as some calculated parameters.
2. Operational Table which contains hours of operation and number of
starts.
Maintenance:
1. Global Occupancy Equipment Table that shows the current occupancy
state and last and next occupancy times.
2. Alarm Status Table that shows current alarm code and alarm
description
3. Chillervisor System Manager Table that shows measured and
calculated parameters.
4. Gateway Messages Table that shows a list of the last 10 Gateway to
Sanyo Controller messages sent.
16
Configuration and Setpoint Tables
There are four Configuration Tables and one Setpoint Table.
Configuration:
1. Global Occupancy Table that can be configured in tabular form. When
configured, the Occupancy Table will control the starting and stopping
of the Sanyo Chiller.
2. Consumable Configuration is used to define up to 16 consumable
points from the Status Display Table.
3. Runtime Configuration is used to define up to 16 runtime points from
the Status Display Table.
4. Alarm Configuration sets the CCN alarm message parameters.
Setpoint:
The single Setpoint Table contains five parameters. The first two are
the chilled and hot water setoints that are read from the Sanyo
controller. These values can be modified from the Sanyo control panel
and are copied to the Gateway Setpoint Table or can be modified in
the Gateway and are copied to the Sanyo controller. The final three
parameters are used by the Gateway for percent load calculation as
part of Chiller System Manager support.
Time Schedule Table
The Time Schedule Table provides a graphical method of configuring the
Global Occupancy Configuration Table.
Get/Set Time & Date
The Sanyo Gateway contains a software clock that is set from the Sanyo
controller on POR and updated every 12 hours. If the Gateway time and
date is reset from CCN then the Gateway writes the new date and time to
the Sanyo Controller.
Start/Stop Chiller
The Sanyo chiller can be started and stopped by forcing the CHIL_S_S
point on the first Status screen. In addition, starting and stopping can be
controlled by the Global Occupancy schedule. To prevent excessive
start/stop cycling of the chiller, a temporary “Safety” level force is applied
to the CHIL_S_S point that remains in effect for 3 minutes. After 3
minutes the Safety level is replace by the normal Service level force.
17
Sanyo Alarms
CCN alarms are annunciated whenever a change in the Sanyo alarm or
alert code is detected. Additional alarms are also generated when a loss of
communication occurs between the Gateway and the Sanyo controller.
Chillervisor System Manager
The CHILLERVISOR System Manager (CSM) is a device that
coordinates multiple chillers to provide optimum chilled water capacity.
Alarm History
Alarm History records the last 25 alarms that have been annunciated to the
Carrier Comfort Network.
18
Operator Interface
Carrier user interfaces (including ComfortVIEW, CCNWeb, i-Vu,
CarrierOne and the System Pilot) are the operator interface to the Sanyo
Gateway. With the Sanyo Gateway connected to a Sanyo controller and a
Carrier Comfort Network (CCN), an operator can add the Sanyo chiller to
the user interface database and upload the Tables.
The default address of the Sanyo Gateway is bus = 0, element = 191.
The default baud rate is 9600 baud.
An operator working at a user interface can:
o Display a list of the points that show current conditions in the
Sanyo controller.
o Modify selected points (force an override) or return them to local
control (auto an override).
o Display configuration and maintenance screens and change
configuration data.
o Create graphics (if supported by the user interface)
There are a total of 11 tabular screens that are uploaded from the Gateway.
o Points screen (16xxSTAT and 16xxOPER, where xx can be either
DJ, NK, TJ or LJ).
o Maintenance screen (OCCPC01M, ALRM-MNT, CSM-MNT and
MESSAGES)
o Occupancy Configuration screen (OCCPC01C).
o Alarm Configuration screen (ALRM-CFG).
o Runtime Equipment Configuration screen (RUN-POC1).
o Consumable Equipment Configuration screen (CNS-POC1).
o Controller Identification screen (CTRL-ID).
The first Points screen displays the current status of chiller parameters
such as status codes, setpoints and operating temperatures. The status of
some of the points can be modified by the operator using a Force function,
which can be removed using an Auto function. These forcible points are:
Name

XXX.X ° F/ ° C
The second Points screen shows hours of operation and number of starts.
19
The Maintenance screens are used to monitor the operation of the Sanyo
Gateway. OCCPC01M shows the current occupancy state of the Time
Schedule. ALRM-MNT shows the current Sanyo alarm code. CSM-MNT
shows the percent load data used for the Chillervisor. MESSAGES shows
the last 10 messages sent from the Gateway to the Sanyo controller.
The OCCPC01C Configuration screen allows tabular configuration of the
Gateway’s Time Schedule.
The Runtime and Consumable Equipment Configuration screens are
RUN-POC1 and CONS-POC1. If Sanyo Gateway points are to be used in
conjunction with the Runtime and Consumable supervisory parts of a Data
Collection Option, this is where the point names and types of those point
names are entered.
The Alarm configuration screen (ALRM-CFG ) is a listing of Sanyo
Gateway’s alarm configuration parameters such as Alarm System Name
and Re-Alarm Time.
The Controller Identification screen lists Sanyo Gateway parameters such
as device name, description and location, and software and assembly part
numbers. The table named CTLR-ID is selected to display this screen.
The Sanyo Gateway can display units in either imperial or metric format
when used with an appropriate Carrier user interface.
20
Network Functions
The Carrier communicating network functions that are relevant to a
Sanyo Gateway is the Data Collection and Data Transfer Options
Data Collection
The Data Collection Option can be used to collect data from any point in
the two Status Display Tables.
Points must be specified by name and type when configuring the Data
Collection Option’s supervisory part. Consumable and Runtime point
names and types must also be configured in the Sanyo Gateway equipment
parts (CONS-POC1 and RUN-POC1).
For more information on the Data Collection Option, refer to the Data
Collection IV Overview and Configuration Manual (808-208).
Data Transfer
The Data Transfer Option can be used to read data from any point in the
two Status Display Tables or to write to a forcible point the first Status
Display Tables.
To transfer data from the Sanyo Gateway a valid point name in either of
the two Status Display Tables is configured in the “Source Variable
Name”, in the Data Transfer module.
These point names are also used when transferring data to the Gateway. A
data transfer to a point results in a controller force on that point. For this
reason, it is recommended that caution be used when transferring data to
the Sanyo Gateway. For more information on the Data Collection Option,
refer to the Data Transfer Option Overview and Configuration Manual
(808-557).

General Information
This section shows the screens that are uploaded for the four Sanyo chiller
types. The only screens that are chiller type specific are the two Status
Display screens that only contain the points that are relevant to the
particular type. Specific information regarding individual parameters is
given following each screen.
Note that for the remote Chiller Stop command to work the Sanyo control
panel must have the REMOTE signal R-SIGN to be configured as PULSE.
Points Screens
The Points list is used to select the Point Status screens. The Point Status
screens displays current conditions read from the Sanyo controller chiller
as well as internal Sanyo Gateway parameters.
The Carrier user interface's force operation can be used to modify the
values of some of the Sanyo Gateway points. Transmitting a force
command to one of these points causes its value to change and the
SUPVSR force message to be displayed against the point.
Using the Auto operation removes the SUPVSR force message from the
screen. Autoing the point does not return to the value it had before being
forced. If a force is applied the CHIL_S_S point to start or stop the chiller,
then to prevent excessive cycling, a temporary “Safety” level force is
applied to CHIL_S_S that remains in effect for 3 minutes. After 3 minutes
the Safety level is replace by the normal Service level force.
Force commands can come from an operator via a user interface, or from
other devices on the Carrier communicating network, such as
CHILLERVISOR System Manager, Data Transfer, or BEST ++.
Figures 5 through 9 show the first Point’s screen that contains Sanyo
controller point status values. The particular screen that is uploaded is
dependent on the chiller type, which is automatically determined by the
Gateway on POR.

Percent Load Calculation
The Chillervisor system manager determines when to add or remove a
chiller from service in a multiple chiller plant. With chillers that provide
electrical cooling the chiller load can be measured in relation to the
percent of full load amps the chiller is consuming. The Chillervisor system
manager has configurable load percentages that are used as a threshold in
the “add and remove” chiller routines.
In order to determine the loading on an absorption machine we cannot
look at full load amps or the valve position on the heat source for the
generator. In order to calculate the percent load of the absorption machine
it is necessary to evaluate the parameters for the absorption cycle.
Several parameters determine how well the absorption machine is
performing and from these parameters we can derive a relative
refrigeration cycle for the current operation of the machine based on startup conditions.
40
During the solution warm up cycle the gateway can calculate a percent
load based on the percent of the hot solution temperature to the
temperature of the primary heating driver in the generator. This allows it
to report a ramp loading effect of the absorption cycle. Relative
differences of the solution concentration, chilled water differential, and
condenser water differential are taken in to account to make sure the
absorption cycle is really developing as the solution in the generator
warms up. Otherwise the Gateway would report the load as increasing so
the Chillervisor would make a determination that something is wrong, stop
this machine and start another machine.
When the solution is warmed up in the generator and the concentrations of
the strong solution and weak solution have spread apart, there is a good
differential on the chilled water in and out and a good differential on the
condenser water in and out. From this is calculated the machines running
load factor. The running load factor is typically in the 50 to 100% range
based on the hot solution temperature and is factored by the strong
solution percentage, the condenser water temperature and the chilled water
difference. A high load percentage is reported when the strong
concentration approaches within 6 or 7 % of the solidification
concentration of 70%. This ensures Chillervisor starts the process of
adding another machine to assist with the load before the concentration
becomes high enough to cause this machine to shut down.
When the machine is requested to shut down it will typically go through a
dilution cycle. The loading is calculated as a number from 50% down to
0% based on the relative difference of the solution concentrations.
The following formulas are used to calculate %load of the chiller.
Ramp Loading just after starting:
% Ramping load =
(High temp Generator temp – High temp Generator temp at startup) * 100
(Max temp of the generator - High temp Generator temp at startup)
Where the Max temp of the generator has the following values for each
machine type.
•
16TJ & 16LJ single effect = 105 C
•
16DJ & 16NK double effect = 162 C
41
Simultaneously the following calculation is performed which will become
the % Running load and the Dilution Cycle percent Load.
% Running load =
(% Conc of Concentrated sol – Design condition of diluted sol) * 100
(64.9 - Design condition of diluted sol)
The design condition of the diluted solution is a user configurable value
with the default value of 55% and a range of 52% to 57%
During Ramp loading the values of chilled water and condenser water
delta should be increasing such that the following delta temperatures are
positive values.
Delta Chilled water
= chilled water return temp – chilled water supply temp
Delta Condenser water
= condenser water leaving temp – condenser water entering temp
When the concentration % Running load becomes equal to or greater than
the % Ramping load and the two deltas have been increasing for the
calculated ramp time, then the calculation switches to the concentration
percent load and stays with that till the machine shuts down and goes
through a dilution cycle.
On start-up, either when the machine transitions from stop to start or if the
Gateway is started when the machine is running, a minimum ramp time is
calculated based on the difference between the Max temp of the generator
and the measured High temp Generator temperature.
The following chart is used to set the ramp to monitor the chilled and
condenser delta temperature before the % Ramping load using generator
temp transitions to % Running load based on concentration.
Generator Max temp - High temp Generator at restart
Difference < 20 C
Difference > 20 C and < 40 C
Difference > 40 C and < 60 C
Difference > 60 C
Time delay
30 sec
60 sec
120 sec
300 seconds
If the concentration of concentrated solution becomes 65% or greater then
the % load based on the concentrated solution is used without waiting for
the ramp delay time to expire. This is because the machine will shut down
if it runs too long above 65% on this concentration.
