swap” the pumps upon detection of a fault, and may avoid the inevitable Flow Loss diagnostic (and
unit shutdown) that will result if there is no fault feedback.
When configured for Dual Pump Fixed Speed, the CH530 will swap pumps on detection of a fault
(if installed), or when a flow loss or overdue event occurs. It will also switch pumps each time the
overall pump request is removed and re-engaged, unless a fault is detected on one of the pumps.
If faults are detected on both pumps, the unit will be shut down.
In addition to the factory installed flow switch, a field-supplied auxiliary contact is required, so that
the chiller will only detect flow if a pump is running and the flow switch says flow is present.
Alarm and Status Relay Outputs (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 Alarm Relay Output Option. The relay’s 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 36.
The relay will be energized when the event/state occurs.
Relay Assignments Using TechView
CH530 Service Tool (TechView) is used to install the Alarm and Status Relay Option package and
assign any of the above list of events or status to each of the four relays provided with the option.
The relays to be programmed are referred to by the relay’s terminal numbers on the LLID board
1A18.
The default assignments for the four available relays of the CGAM Alarm and Status Package
Option are:

Description
Alarm - Latching
This output is true whenever there is any active diagnostic that requires a manual reset to clear, that affects either the
Chiller, the Circuit, or any of the Compressors on a circuit. This classification does not include informational diagnostics.
Alarm - Auto Reset
This output is true whenever there is any active diagnostic that could automatically clear, that affects either the Chiller,
the Circuit, or any of the Compressors on a circuit. This classification does not include informational diagnostics.
Alarm
This output is true whenever there is any diagnostic affecting any component, whether latching or automatically clearing.
This classification does not include informational diagnostics
Alarm Ckt 1
This output is true whenever there is any diagnostic effecting Refrigerant Circuit 1, whether latching or automatically
clearing, including diagnostics affecting the entire chiller. This classification does not include informational diagnostics.
Alarm Ckt 2
This output is true whenever there is any diagnostic affecting Refrigerant Circuit 2 whether latching or automatically
clearing, including diagnostics effecting the entire chiller. This classification does not include informational diagnostics.
Chiller Limit Mode (with
a 20 minute filter)
This output is true whenever the chiller has been running in one of the Unloading types of limit modes (Condenser,
Evaporator, Current Limit or Phase Imbalance Limit) continuously for the last 20 minutes.
Circuit 1 Running
This output is true whenever any compressor is running (or commanded to be running) on Refrigerant Circuit 1, and false
when no compressors are commanded to be running on that circuit.
Circuit 2 Running
This output is true whenever any compressor is running (or commanded to be running) on Refrigerant Circuit 2, and false
when no compressors are commanded to be running on that circuit.
Chiller Running
This output is true whenever any compressor is running (or commanded to be running) on the chiller and false when
no compressors are commanded to be running on the chiller.
Maximum Capacity
This output is true whenever the chiller has all compressors on. The output is false once one compressor is shut off.
