The ASIC/2-7540 can operate as part of a larger
communicating control network with other ASI
controllers. Communication at speeds up to 19,200 baud
on both the system and local bus means rapid access to
information. Temperatures, setpoints, and other
controller information may be easily reported to ASI
WebLink, or any Windows based software that is a client
for OLE for Process Control (OPC). The controller has
separate RS-485 system and local buses. No central
system is needed to supervise the controller. Red and
green LEDs indicate the controller receive and transmit
communications.

System Trouble-Shooting
This Section will describe how to trouble shoot the system in
case of faulty
Communication Failure Problems communicating with ASIC controllers can usually
be attributed to one (or more) of five areas:
Software not configured to use the correct serial port
Incorrect RS-232 cable attached to the serial port
Trouble with the RS-485 bus
Blown Pico-fuse
Blown RS-485 Chip
Software and RS-232
Cable
One way to test the software and cable is to connect the PC
to a SINC/3-3000 with a serial cable. It is not necessary to
connect the SINC/3-3000 to an ASIC controller for this test.
Start ASI Expert and click Find It. The Local LED should turn
off and the red Tx LED should blink as ASI Expert attempts
to find a controller. A straight-through serial cable is required
to connect the PC to the SINC/1-1030.
Check the Software You should first then check your software to make sure that
the software is set with the correct COM port, baud rate and
stop bits settings. These settings can be found by clicking
Options | System Options in ASI Expert. Typical settings are
COM1 or COM2, 9600 or 19200 baud, and 2 stop bits.
When directly connected to an ASIC controller, 2 stop bits
must always be used. The software generates a warning
message if another application is using the designated COM
port. The Multi-baud Enable box may be checked if baud
rate is not known. If the red Tx LED does blink, then the
software and serial cable are working correctly.
Check the Cable The RS-232 cable can be tested with a multi-meter by
testing for continuity (or resistance) between pin 2 at each
end of the cable. Check pin 2 for continuity If the multi-meter
shows that the pins are linked, then the cable should be fine.
Doc: O&M/Sec4/UNITEN/2010
Section 4
ASI Controls Building Monitoring System Page 4-3 Operation & Maintenance Manual
If the pins are not linked then you may have a NULL Modem
cable.
Communicate with
ASIC
To communicate with the ASIC controller connect the
SINC/1-1030 to the wall sensor of the ASIC controller. Make
sure that the end of the curly cable with the jumper is
plugged into the wall sensor. This jumper provides an
interlock to specifically identify the controller. In ASI Expert
Software Click on Options | System Options and check the
Multi-baud Enable and 2 Stop Bits boxes, if they are not
already checked. In the ASI Expert Find It dialog select
ASIC, then click Find It, leaving the address field blank. ASI
Expert will then search all baud rates for an ASIC controller.
The LED on the SINC/1-1030 will blink as it tries. If the
controller is not found at any baud rate, remove the RS-485
remote network connector, TB4, located below the wall
sensor connector and click Find It again. If the controller is
found with the connector removed, then either there is
another controller on the network that is causing the
problem, or there are problems with the network wiring.
Check Pico-fuses If the controller is still not found, then check the pico-fuses,
identified as R5 and R6 for continuity. They are located at
the edge of the board near the 24Vac power terminals.
Replace any blown fuse with a 1/8 amp fast blow pico-fuse
(ASI Part Number PFK-125). Another way to check the pico-
fuses is to disconnect the SINC/1-1030 from the wall sensor
, remove the RS-485 remote network connector, TB4, and
then measure DC voltage at the + and – communication
terminals, referenced to ground. If there is 0 VDC between
ground and +, then R5 is blown; 0 VDC between ground and
– indicates that R6 is blown.
RS-485 Chip If the pico-fuses are not damaged, then replace the RS-485
communications chip, identified as U2 above the wall sensor
connector, with one from a controller that is known to
Doc: O&M/Sec4/UNITEN/2010
Section 4
ASI Controls Building Monitoring System Page 4-4 Operation & Maintenance Manual
communicate properly. Be sure to turn off power to the
controller when removing or installing this chip. Also be sure
to install the chip at U2 correctly so that the circle identifying
pin 1 is in the upper left hand corner when the controller is
viewed with the transformer at the top. If replacing U2 fixes
the communication problem, contact ASI Controls for a
replacement chip.
For Further Assistance If you still are unable to communicate with the ASIC
controller after following the above instructions, contact ASI
Solutions Sdn Bhd at 603-5510 3885 for further assistance.

Maintenance Procedure
This Section will describe ASI standard maintenance
procedure.
Preventive Maintenance Service
Performance Criteria Preventive maintenance are the equipment tasks to be
performed to prolong the life cycle of the BAS components
as well as the calibration procedures necessary to ensure
accurate readings and control response. Proper preventive
maintenance will extend the equipment component life and
reduce the costs associated with repair calls. ASI Controls
System hardware was designed to require less preventive
maintenance than our competitors’ systems. The major
problem areas with older generation systems were identified
and the solutions were designed and rectified into ASI
Controls System.
The periodic maintenance requirements of ASI Controls
System equipment are minimal. This is primarily due to
improvements in the product design. Most of other BAS
manufacturer uses Network Control Unit (NCU) that has a
complete set of BAS features for the connected DDC
Controllers and integrated subsystems. As the NCUs
provide essential functions for a large number of points
(about 1000 points), the DDC will be fully dependent on the
NCU. Upon failure of any NCU, the DDC process will be
halted and the system scheduling is no longer in functional.
ASI Controls System does not depending on the NCU as our
DDC are all equipped with the features that most of other
NCU performs. Some of the BAS manufacturers are
proposing a hot and standby system for an NCU. This will
force the building owner to spend more in order to have a
reliable system without single point of failure in the NCU. In
Doc: O&M/Sec5/UNITEN/2010
Section 5
ASI Controls Building Monitoring System Page 5-3 Operation & Maintenance Manual
current technology, the NCU shall be acting as a
communication manager only where it only gathers
information from the DDC and manages the system network.
Today's system is a system that can operate independently
and standalone and therefore do not require the hot and
standby system.
In addition, software supervises all system command
operations. Error messages are generated to alert the
operations staff whenever a manual request or an
automatically initiated request fails to perform as expected.
Advisory messages are also generated when
communication between various elements on the network is
interrupted for an extended period of time.
The Operator Workstations provide information management
for the system. The loss of an Operator Workstation will not
affect any of the BAS features of the system. In addition,
historical data is archived concurrently at multiple Operator
Workstations (if any) so that the failure of a hard disk does
not result in the loss of information. Our ASI Operator
Workstation is installed with the powerful ASI Weblink web
based GUI. The software act as the front-end web-user
interface and also as a communication manager.
Basic Preventive Maintenance
We propose quarterly scheduled service visits to the site.
Each visit will include:
Review of operations
Central Equipment Maintenance
Field Equipment Maintenance (each visit will cover 25%
of the field equipment)
Following this preventive maintenance strategy, operations
and central equipment is checked quarterly and field
equipment is checked annually.
Task 1 - Review of Operations
A scheduled service visit to the site will begin with a review
Doc: O&M/Sec5/UNITEN/2010
Section 5
ASI Controls Building Monitoring System Page 5-4 Operation & Maintenance Manual
of job site system event log and a discussion with the
system operators. A number of key summaries will be
printed. Within one week of the visit, the ASI service
representative will submit a report on the visit as a proof of
service. This report will include the following:
List of services performed on the central equipment with
results, if any
List of field equipment serviced and services performed
with results, if any
Copies of the summaries with comments.
List of concerns expressed by operations staff,
identifying person responsible and time frame for follow-
up
Task 2 - Central Equipment Maintenance
On each quarterly visit, the service representative will:
Scan hard disk for common “virus” programs
Check database, directory structure of hard disk
Check hard disk for lost chains
Optimize hard disk
Verify PC memory self-test and initialization processes
Listen for fan, floppy and Winchester drive motor or
bearing problems
Clean exterior surfaces
Task 3 - Field Equipment Maintenance (Digital Controllers)
Our experience is that the Digital Controllers require very
little servicing once they have been set up. The types of
tasks performed as part of preventive maintenance include:
Verify field power supply voltage
Check and record system DC isolation from chassis
ground
Change a setpoint and verify a change in the controlled
output
Clean exterior surfaces
Task 4 - Verify Inputs and Outputs Points
The trustworthiness of each point in the system is verified
once per year. For analog points, this means measuring the
Doc: O&M/Sec5/UNITEN/2010
Section 5
ASI Controls Building Monitoring System Page 5-5 Operation & Maintenance Manual
sensed variable and comparing the reading to the display on
the BAS. For binary points, this means actually simulating a
change of state on the equipment and verifying that the
message reports back to the BAS. It is not sufficient to
merely short the input at the controller, the actual field
condition being monitored must be simulated such as a trip
alarm or flow switch closure. Only in this way can problems
caused by people disabling input devices be detected.
Critical Point Verification
We recognize that there may be points or control loops,
which are critical to your operation. The reliability of these
points and loops must be verified by direct visual inspection
due to the serious impact their failure would have on your
operation. ASI will establish with the operations personnel
those points, which fall into this category and establish a test
plan for each point.
Database Protection We shall periodically back-up from your operator
workstations, the system database, any user-defined
software enhancements, trends and point history. Regular
database back-up are designed to significantly reduce
downtime in the event of hardware or software failure.
Corrective Maintenance
Performance Criteria The Corrective Maintenance Service is intended to minimize
the equipment downtime in the event of a failure. Depending
on the level of coverage selected, the customer will have
varying levels of protection against unbudgeted costs.

Irrespective of the level of corrective maintenance chosen,
ASI provides a defect liability period of twelve months.
During the defect liability period, there will be no charge for
any material replacements required due to normal wear and
tear on the system. The labour required to effect such
replacements will not be charged.
Service Level 3 - No Repairs Included
If this option is chosen, parts that require replacement and
are not covered by the defect liability clause will be charged.
Labour for work not covered by the defect liability clause will
be charged. Examples of parts and labour costs that are not
covered by the defect liability clause include costs
associated with fire, vandalism, water damage, tampering,
etc.
If this option is chosen, there is no guarantee of response
time and complaint calls, for which ASI is not responsible,
such as a switch being left in the hand position, will be
charged out. If this option is chosen, there is no guarantee
that repair parts will be kept locally.
Service Level 2 - Minimum Repair Coverage
If this option is chosen, parts that require replacement and
are not covered by the defect liability clause will be charged.
Labour for work not covered by the defect liability clause will
be charged. If this option is chosen, a preferred labour
charge out rate for engineers is applied. After the defect
liability period, all parts and labour will be charged.
Examples of parts and labour costs that are not covered by
the defect liability clause are costs associated with fire,
vandalism, water damage, tampering, etc.
If this option is chosen, there is a guaranteed response time
of 4 hours. Complaint calls, for which ASI is not responsible,

chosen, there is no guarantee that repair parts will be kept
locally.
Service Level 1 - Comprehensive Repair Coverage
If this option is chosen, parts that require replacement and
are not covered by the defect liability clause will be charged.
Labour for work not covered by the defect liability clause will
be charged. If this option is chosen, a preferred labour
charge out rate for engineers is applied. After the defect
liability period, parts and labour required due to fair wear and
tear will not be charged. Examples of parts and labour costs
which are not covered by the defect liability clause and are
not considered to be fair wear and tear are costs associated
with fire, vandalism, water damage, tampering, etc.
If this option is chosen, there is a guaranteed response time
of 2 hours. Complaint calls, for which ASI is not responsible,
such as a switch being left in the Hand position, will not be
charged out. ASI will guarantee that all required repair parts
manufactured by ASI will be stocked locally.
Employee Attachment Service
Performance Criteria Employee Attachment is designed to provide the following
benefits to the customer:
The customer’s engineers will understand ASI Controls
System capabilities before the software database is
generated. The engineers can then make suggestions
and provide input to ASI so that the system is designed
to meet operational requirements.
The customer’s technicians will be better equipped to
carry out daily functions, as they will have a better
understanding of the system operations.
To meet these two objectives, the following type of
employee attachments are available :
Engineer attachment service
Doc: O&M/Sec5/UNITEN/2010
Section 5
ASI Controls Building Monitoring System Page 5-8 Operation & Maintenance Manual
Engineer Attachment Service
This training takes place from the beginning of the system
configuration. The customer’s engineer will work closely with
the ASI application engineer. This provides an informal
interactive learning environment with practical “hands-on”
experience. An operator workstation with attached field gear
is set up in the branch to develop the system with the
customer’s engineer. The areas covered during this
attachment include:
ASI Controls System architecture
ASI Controls System capabilities and features
Hands-on system application
System design interaction
System expansion capabilities
During the attachment process, the ASI engineer will discuss
with the customer’s engineering the operational
requirements for the facility. Together they will design the
application of the features to best suit the requirements.
As the customer’s is involved with the design decisions for
the system, he will feel grater ownership, understanding and
involvement with the system. Familiarizing the engineer with
the system at this early stage will help him plan as to how
the facility operations will be affected by the system.
Periodic Maintenance Schedule Checklist
The following table shows the proposed maintenance
schedule and the checklist of task that is to be undertaken
during the visit.
Please note that the schedule visit will be made quarterly.
Task that has been identified to be service quarterly will be
done at every visit. At least 25% of those equipments that is
under annual service will be service during each of the visit.

ASI Visual Expert is the software for configuring ASI control systems. Visual Expert provides an integrated development environment for controller configuration, debugging and commissioning systems, setting-up control networks, documenting projects, and performing updates and maintenance.
ASI Visual Expert makes configuration simple. Users drag functional objects on screen, make connections between onscreen objects, then set each object’s properties. There is no line programming involved, and the real-time data display provides feedback so that sequences can be verified as they are being developed.
Configuration data stored at the controller level can be backed up in Visual Expert, simplifying swapping out a device or devices in an existing network. Configuration data can also be read directly from the controller, so that any Visual Expert user can remotely connect and monitor or reconfigure an existing system. Any instance of Visual Expert can upload configuration data from any connected controller and/or download data to any controller.
Visual Expert operates in either Online or Offline mode. In Online mode users can upload current data from any connected controller, modify configurations, and download configuration data to any connected controllers. In Offline mode users can view and modify only the configuration information stored locally on the computer running Visual Expert. Changes are downloaded to controllers when they are connected.
The software can connect to controllers directly over a wire or modem, or across Local or Wide Area Networks or the Internet - using either TCP/IP or UDP - so that system start-up and maintenance can be performed remotely from a convenient location. A hierarchical tree provides access to all controllers in the currently connected project, and to all controllers in all the projects archived on the local computer.
Users can create Function Groups to implement a common sequence or logical task. The Function Groups can be exported for re-use on other projects, increasing productivity while also ensuring consistency across projects. Some examples of Function Groups include Time of Day Scheduling, Economizer Sequence, Heating and Cooling Calculation, and Compressor Staging with minimum on and off times.

ASI LinkOPC is an OPC Server software application. LinkOPC connects Windows-based applications to ASI Controls systems, and enables a wide range of third-party OPC enabled software and hardware products to interoperate and communicate with ASI Controls systems.
OPC is an open, vendor-neutral set of standards originally created by a number of leading industrial automation companies in collaboration with Microsoft. The OPC Data Access (OPC-DA) standards define the methods for exchanging real-time automation data among OPC Clients.
OPC-DA eliminates the need for vendor-specific drivers for each control system by defining a common, high performance data exchange interface layer that is open and accessible by HMI, SCADA, control, and custom applications.
ASI LinkOPC is compatible with both OPC-DA 1.0 and 2.0. It is optimized for data retrieval to ensure fast throughput. Built-in tag optimization minimizes the overall number of data transactions, reducing system traffic
ASI LinkOPC includes tag browsing to assist with rapid development of client applications. ASI points can be mapped to OPC tags and exposed to OPC Client applications by pointing and clicking in the OPC tag browser window.
Polling prioritization is a LinkOPC feature that allows the developer of the HMI client to update ASI control points at different intervals. This feature is useful when tuning the responsiveness of HMI screens displaying multiple points. Static data can be assigned a lower polling frequency to allow dynamic data to be updated at more frequent intervals.
LinkOPC can communicate with ASI devices through a serial port, modem connection, or over TCP/IP and UDP connections. LinkOPC can support simultaneous connections using any or all of the methods. The LinkOPC OPC Server can be located on the same computer as an OPC Client application, in which case communications will utilize Microsoft COM, or be on a different computer and communicate over a network using DCOM. LinkOPC can communicate with an ASI Controls system using a com port or via modem.
ASI controllers and control systems can also be connected to ASI LinkOPC via Ethernet TCP/IP networking using an ASI EtherLink/2 serial-to-Ethernet router. The LinkOPC server connects to the EtherLink/2 and transfers ASI message requests via TCP/IP. The LinkOPC server can connect with multiple EtherLink/2 devices simultaneously to efficiently monitor and control multiple remote sites in a single OPC Client front end such as ASI WebLink.
ASI LinkOPC Features
• Provides Interoperability
• Easy to Configure
• Communicates over Ethernet
• Integrates with ASI Visual Expert and WebLink
• Fast Response Times
• OPC Tag Browser

Overview
The 212 Heat Calculator is designed tomeasure the energy consumed in hotwater heating systems and chilled watercooling systems.
The 212 is supplied complete with temperature probes and will interface with a wide range of flowmeters, includingpositive displacement and inferential water meters, magnetic flowmeters withpulse outputs, turbine and paddle wheelflowmeters.
Provides flexibility tomeet all applicationsThe 212 is able to cross internationalboundaries in heat meter applications.
Multilingual capability, datalogging andpeak/off-peak operation are standard. Inaddition, four modes of operation coveringheating and cooling ensure that the 212 is flexible enough to meet all energymeasurement applications.
The high accuracy of the 212 ensures thatit meets European and Internationalapprovals for heat calculators.
Accuracy to OIML R75Class 4 and EN1434The 212 can be supplied with two precision 4-wire Pt100 RTDs and hasinbuilt correction for the non-linearity ofthe RTDs. For chilled water measurementwhere the temperature difference (∆t) islikely to be small, provision is made in theset-up program to zero out any offsetbetween RTDs.
The 212 is fully programmable and all set-up data and totals are stored in a non-volatile memory for a minimum of 10 years.
Watertight wall or panelmount enclosureThe 212 Heat Calculator is housed in arugged yet attractive IP66 (Nema 4X) rated polycarbonate enclosure which iscompletely watertight.
Mounting is either by a wall bracket or bypanel mount.

Integration with energymanagement systemsA Meter-bus interface enables the 212 HeatCalculator to be incorporated into energymanagement systems complying withEuropean IEC 870-5 protocol standards.
The 212 is also supplied with an RS485 bus,which uses industry standard Modbus RTUprotocol, for interfacing to computers andDCS systems.
Datalogging flexibility
The 212 Heat Calculator will store energytotals by hour, day, week or month for up to31 periods. The totals are stored for eachperiod and can be downloaded to a computervia the Meter-bus or RS485 communicationsports.
Peak and off-peak registers
If selected, the peak/off-peak feature willassign two separate registers which willtotalise peak energy and off-peak energy.
The changeover times between peak and off-peak are fully programmable.
4-20mA Output
A 4-20mA output option is available and canbe programmed to output flow rate, energyflow rate, feed or return temperature or ∆t.
Note that the high and low alarms are notavailable if the 4-20mA option is installed.
Modes of Operation
The 212 Heat Calculator is flexible enough tohandle a wide range of applications. Fouroperating modes are available.
❿ Heating Mode where positive ∆t’s only are totalised.
❿ Cooling Mode where negative ∆t’s onlyare totalised.
❿ Heating/Cooling Mode where the flow of energy may be for heating or cooling.In this mode the energy total is increasedregardless of whether ∆t is positive or negative.
❿ Charge/Discharge Mode where two separate registers totalise positive andnegative totals.
Calculates the density andenthalpy of water
The 212 Heat Calculator measures the temperature in the feed and return lines and, from this, calculates the density andenthalpy of the water.
By also measuring the volume of water flowing in the system, the 212 will then compute the energy consumed.
Power is calculated as:
P = V x p x (hTV - hTR)
where P = Power (W)V = Volumetric flow rate (m3/s)p = Density (kg/m3)hTV = Specific enthalpy (J/kg) at
Feed temperaturehTR = Specific enthalpy (J/kg) at
Return temperature
The volume, energy, temperatures and peak energy are all calculated and can bedisplayed on the large LCD.
