Programmable Relays
A programmable relay concept provides for enunciation of certain events or states of the chiller, selected from a list
of likely needs, while only using four physical output relays, as shown in the field wiring diagram.
The four relays are provided (generally with a Quad Relay Output LLID) as part of the Programmable Relay Option.
The relays contacts are isolated Form C (SPDT), suitable for use with 120 VAC circuits drawing up to 2.8 amps
inductive, 7.2 amps resistive, or 1/3 HP and for 240 VAC circuits drawing up to 0.5 amp resistive.
The list of events/states that can be assigned to the programmable relays can be found in Table (…) Chiller events/
Status description. The relay will be energized when the event/state occurs.
Table 3 –
Chiller event/status descriptions
Alarm - Latching This output is true whenever there is any active latching shutdown diagnostic that targets the Unit, Circuit,
or any of the Compressors on a circuit.
Alarm - NonLatching This output is true whenever there is any active non-latching shutdown diagnostic that targets the Unit,
Circuit, or any of the Compressors on a circuit.
Alarm This output is true whenever there is any active latching or non-latching shutdown diagnostic that targets
the Unit, Circuit, or any of the Compressors on a circuit.
Alarm Ckt x This output is true whenever there is any active latching or non-latching shutdown diagnostic that targets
Circuit x, or any of the Compressors on Circuit x.
Unit Limit Mode This output is true whenever a circuit on the unit has been running in one of the limit modes continuously
for the Limit Relay debounce time. A given limit or overlapping of dierent limits must be in eect
continuously for the debounce time prior to the output becoming true. It will become false if no limits are
present for the debounce time.
Compressor Running The output is true whenever any compressor is running.
Circuit x Running The output is true whenever any compressor of Circuit x is running.
Ice Building This output is true when Ice Building status is active.
Maximum Capacity The output is true whenever the unit has reached maximum capacity continuously for the Max Capacity
Relay s time. The output is false when the unit is not at maximum capacity continuously for the lter time.
Evaporator Water
Freeze Avoidance
Request
This relay output is energized any time either the Low Evaporator Water Temperature – Unit O or the
Low Evaporator Temperature Ckt x – Unit O diagnostics are active. This relay is intended for use as an
external interlock for a eld engineered and provided solution to mitigate the freeze danger implied by
these diagnostics. Generally, this would be used in cases where operation of the evaporator water pump is
unacceptable due to the system constraints, (i.e. such as mixing unconditioned warm water with controlled
supply water as provided by other parallel chillers. The relay’s output can provide the method to close
bypass valves so the circulation becomes local to the evap and excludes the load, or can be used to defeat
the evap pump override entirely while initiating an independent source of heat / ow to the evap.
None: On Multi-pipe units, it mandatory to connect Evaporator Freeze avoidance relay output to pump or valve
that rapidly establish evaporator water ow even if unit is in AUTO mode.
This selection is desirable to provide an easy way for a customer to defeat the eect of the relay, if it has
already been wired. For instance, if the relay was normally programmed as an “alarm” relay, and was
wired to a claxon, it may be desirable to temporarily defeat the feature without changing wiring.
Service request (for
Unit, Compressor(s)
or water pump):
This relay will be energized when at least one Maintenance alert condition (refer to Service required
message specication) occurs, as long as at least one of associated informational diagnostic(s) will be
active.
Warning
The output is true whenever there is any active warning diagnostic that is associated with the Unit, Circuit, or any of
the compressors on a circuit.
