Condenser Water Pump Control
Tracer UC800 provides a contact closure output to start
and stop the condenser water pump. It will allow to run
the condenser pump after compressor stop to avoid risk
of freezing due to refrigerant migration from evaporator.
Condenser Water Pump Prestart time has been added to
help with cold condenser water problems. In very cold
outdoor ambient, the cooling device’s sump would reach
the chiller some time after the low system differential
pressure protection had run through its ignore time,
and result in an immediate shutdown and latching
diagnostic. By simply starting the pump earlier, and
allowing mixing of the warmer indoor loop with the
cooling device’s sump, this problem can be avoided.
Condenser Water Flow Interlock
The Tracer UC800 shall accept an isolated contact closure
input from a customer installed proof-of-flow device
such as a flow switch and customer provided pump
starter auxiliary contact for interlocking with condenser
water flow.
The input shall be filtered to allow momentary openings
and closings of the switch due to turbulent water flow,
etc. This shall be accomplished with a 6 seconds filtering
time. The sensing voltage for the condenser water flow
switch is 115/240 VAC.
On a call for cooling after the restart inhibit timer has
timed out, the Tracer UC800 shall energize the condenser
water pump relay and then check the condenser water
flow switch and pump starter interlock input for flow
confirmation.
Startup of the compressor will not be allowed until flow
has proven. If flow is not initially established within
1200 seconds (20 minutes) of the condenser pump
relay energizing, an automatically resetting diagnostic
“Condenser Water Flow Overdue” shall be generated
which terminates the prestart mode and denergizes
the condenser water pump relay. This diagnostic is
automatically reset if flow is established at any later
time.
Note: This diagnostic would never automatically reset
if Tracer UC800 was in control of the condenser pump
through its condenser pump relay since it is commanded
off at the time of the diagnostic. It could however reset
and allow normal chiller operation if the pump was
controlled from some external source.
Programmable Relays (Alarm and Status)
Tracer UC800 provides a flexible alarm or chiller status
indication to a remote location through a hard wired
interface to a dry contact closure. 4 relays are available
for this function as a Quad Relay Output LLID and
a second quad relay board can be field mounted if
more than 4 different alarm/status are needed (refer to
your local Trane service). The events/states that can be
assigned to the programmable relays are listed in the
following table.
