SKM Compact Screw ChillersAPCN Series - R134a
General Features
High COP
APCNSerieschillers provide tremendous savings in operatingcosts by using high efficiency, semi hermetic compact screw
compressor. High COP is made possible due to perfect screw
profile and precise machining. The stepless capacity control
provides precise capacity as required by the system load, and
thus giving higher part load efficiencies. The compressor canbe loaded from 25 to 100% of capacity depending upon the
requirement through state of the art microprocessor control
which precisely monitors the water temperature and accurately
modulates the compressor accordingly.
Maintenance Free Operation
APCN Series chillers have compact design and are supplied as
a complete package, ready to be wired and piped for operation.
Screw compressors in SKM APCN Series provide virtually
maintenance free operation as there are fewer moving parts.
Special bearings facilitate longer run periods of compressor
without any need for maintenance.
Wide Operating Range
APCNchillers are designed, as standard, to operate at a wide
range of ambient temperatures from 25oF (-4oC) to 140oF
(60oC).

Optional Features available for Magnum
PC Support Software for Magnum
MCS-Connect program provides both local and remote
communications to the MAGNUM independent of the type ofsoftware. Through this program, the status of the controller can
be viewed and proper authorization changes can be made to
the system. Configuration files can be transmitted to or received
from a Magnum unit. The Magnum automatically performs history
logging; this program has complete graphic functions.
485 Network
The MCS 485 Network can support up to 20 Magnums and their
associated I/Os. Access to this network can be local, via RS 232
connection, or remote via 14.4K Baud modem. When using the
dial up through the modem, there will be no degradation in the
performance of the network. Each Magnum in the network must
be assigned to a unique address when the configuration file isbuild using MCS-Configprogram. This address will be the key
in establishing communications with the appropriate Magnum
system. This address can be changed from the LCD/keypad
of the unit. The current address of Magnum can be viewed or
changed with factory authorization. RS 232 transmission should
not exceed 30 feet in length and RS 485 transmission should
not exceed 1 mile without repeater.

BMS Communication Protocols
Magnum supports BACnet MSTP, BACnet IP, Modbus RTU,
Modbus TCP/IP, Lonworks and Johnson N2. Each protocols
are supported with various baud rates.
Since green buildings are the major issue in HVAC industrryand building integration is one of the tools to save energy.
Complete control of the chillers along with the monitoring is
possible if any of the above protocols are used to connect chillersto the BMS. The details of the parameters to be controlled,
number of chillers in the building, the protocol, etc., are required
before the order as costing of the BMS interface depends on
these parameters.
Hard Wired of BMS Connection
Within the hard wire structure there are fi ve options as
follows:
1. Run / Stop (BMS to Magnum) A Run / Stop input is provided, by chiller, to allow the end
user to provide an enable / disable signal from a building
management system. This input allows for a normal shutdownof the chiller package.
2. Emergency Stop (BMS to Magnum)
The EMER. STOP input is an input that allows for immediate
shut down. This feature is used for safety, especially in
explosion proof installations. The chiller bypasses the normal
shutdown and shuts down immediately.
3. Chill ed Water Reset (BMS to Magnum) Max Trg
Reset
Is a function of a signal from the building management
system. This value is used to adjust the control LEV LIQTARG set point #1. The amount of the actual adjustment
is proportionally based upon the associated analog input
value. The analog value can be between 0 and 5 volts.
4. Compressor Run (Magnum to BMS)
This is a relay output (VFC) closure from the Chiller Controls
to the BMS indicating the compressor/s is/are running.
5. Alarm (Mag num to BMS)
This is a relay output (VFC) closure from the Magnum to
the BMS indicating a problem. Communications to analysis
