Installation - Electrical
LonTalk Communication Interface - Optional
Tracer UC800 provides an optional LonTalk
Communication Interface (LCI-C) between the chiller and
a BAS. An LCI-C LLID shall be used to provide “gateway”
functionality between the LonTalk protocol and the
chiller.
Bacnet Communication Interface - Optional
Tracer UC800 provides an optional Bacnet
communication interface between the chiller and a BAS.
Bacnet communication capability is fully integrated on
UC800. For further information see Integration Guide.
Modbus Communication Interface - Optional
Tracer UC800 provides an optional Modbus
communication Interface between the chiller and a BAS.
Modbus communication capability is fully integrated on
UC800. For further information see the Integration guide.
Ice Making Contact - Optional
Tracer UC800 accepts a contact closure input to
initiate Ice Building. When in the ice building mode,
the compressor will be fully loaded (not given a low
setpoint) and will continue to operate until the ice
contacts open or the return water temperature reaches
the Ice Termination Setpoint. If terminated on return
setpoint, Tracer UC800 will not allow the chiller to restart
until the ice making contact is opened.
Ice Machine Control - Optional
Tracer UC800 provides an output contact closure that
can be used as a signal to the system that ice building
is in operation. This relay will be closed when ice
building is in progress and open when ice building has
been terminated by either Tracer UC800 or the remote
interlock. It is used to signal the system changes required
to convert to and from ice making.
External Chilled Water Setpoint - Optional
Tracer UC800 will accept either a 2-10 VDC or a 4-20 mA
input signal, to adjust the chilled water setpoint from a
remote location.
Auxiliary Chilled/Hot Setpoint Contact - Optional
Tracer UC800 accepts a contact closure input to switch
from BAS/External/Front Panel setpoint to a customer
defined auxiliary setpoint. By default, chilled water
auxiliary setpoint is set to 9°C and hot water auxiliary
setpoint is set to 33°C.
External Current Limit Setpoint - Optional
Tracer UC800 will accept either a 2-10VDC or a 4-20mA
input signal to adjust the current limit setpoint from a
remote location.
Percent Condenser Pressure Output - Optional
Tracer UC800 provides a 2-10 VDC analog output to
indicate condenser pressure in percent of software High
Pressure Cutout (soft HPC).
Percent HPC =(Lowest Condenser Pressure of all running
circuits (abs) / Soft HPC (abs))*100.
Refrigerant Differential Pressure Indication - Optional
Tracer UC800 provides a 2-10 VDC analog output
to indicate refrigerant differential pressure with the
endpoints customer defined.
Refrigerant Differential Pressure = Lowest of (condenser
refrigerant pressure cktx - evaporator refrigerant
pressure cktx).
Compressor Percent RLA Output - Optional
Tracer UC800 provides a 0-10 Vdc analog output to
indicate %RLA of compressor starter average phase
current. 2 to 10 Vdc corresponds to 0 to 120% RLA.
