AquaLink® RS Troubleshooting

1 Controller

Operation:

The Indoor Controller serves as a means of entering and viewing information for equipment settings. All
programs, labels, etc., are held in a memory chip on the Power Center Printed Circuit Board. Power is not
required to maintain programs, etc. - they will be held indefinitely .
The Controller is supplied 10 VDC from the power center via the outside two wires (red and green) of the
4 conductor cable. The inner two wires (yellow and black) provide the communication link between the
Controller PCB and Power Center PCB.
If either of the communication wires are broken ("open circuit"), but the power supply wires are connected,
the display screen will indicate a break in communication by displaying the controller part number and the
version letter of the Micro Controller (e.g., 6543 REV B01 or 6700 REV C).
Pressing the Reset button, located on the left side of the Indoor Controller, will momentarily display the
software part numbers and revision letters for both the Controller's Micro-controller chip and the Power
Center's PPD chip. The Reset button also resets the Micro-controller, but does not remove any programming,
AUX labels, etc. (see chart on Page 16 for list of Part Numbers).

Time/Date Backup: Supplied by 9-volt battery located at Power Center
Programming and Memory Backup: Stored in EEPROM on Power Center PCB, stored indefinitely ,

even with no power to unit.

2 Power Center

Power Center Operation:

The Power Center PCB is the true brain of the system. The micro-controller on the PCB is constantly sending
signals through the communication wires to the Controller and polling the system to determine which circuits should
be on and which should be off. When an equipment button, such as Auxiliary 1, is pressed, impulses are sent via
the communication wires (yellow and black) between Power Center micro-controller and the Indoor Controller
micro-controller. If all impulses received at the Power Center micro-controller are consistent, the system then looks
at the DIP Switch settings to determine if an option for this circuit has been set. If the DIP Switch settings do not
indicate a delay is needed, signals are sent back to the Controller to turn on the appropriate LED and display the
ON message. At the same time, a signal is sent to one of the two Driver Chips on the Power Center PCB.
The Driver Chips can be thought of as a series of small relays. When one of the Driver Chips receives a signal,
it closes a contact which passes 24 VDC to the appropriate relay coil socket, in this case AUX 1. Each relay driver
chip activates a specific set of relay coil sockets (see the chart below). If a Driver Chip fails, it is usually caused by
either shorted relay coil wires, a shorted relay coil, or a relay not designed for the 24 VDC coil voltage (i.e., 24 V A C
rather than 24 VDC).
The Reset button, located in the upper left hand corner of the Power Center Bezel, when pressed, resets the
Power Center micro-controller and changes time and date to the default settings (i.e., 1:00 P.M. 01/31/96 WED).
Pressing this button will not remove any programming, AUX labels, etc.

Memory:

All programming, labeling, temperature settings, etc., are stored within a EEPROM (Electronically Eraseable
Programmable Read Only Memory) chip. This chip is located on the PCB and will retain all settings indefinitely ,
even if power is lost for an extended period. To remove information from the system, either press the Cancel button
to remove individual items, or the Clear Memory item from the Menu, to reset all items to their default settings. The
battery attached to the PCB is only needed to keep the clock running during a power outage, so when power is

restored, time and date will be correct.

3 Standard Relays

Operation:

A Standard Relay's coil is supplied 24 VDC from the Power Center PCB via one of the two driver chips.
When 24 VDC is received by the relay's coil wires, it closes the contacts that complete the circuit to turn on the
equipment (i.e., power supplied to Line 1 goes out Load 1 to the equipment).
Standard Relays may be wired to activate a 1 10 VAC circuit (e.g., Line 1/Load 1) or a 220 VAC circuit
(e.g., Line 1/Load 1 and Line 2/Load 2).

NOTE: If a relay's coil wires are shorted, or an AC relay coil is plugged into a relay socket, when that circuit is
activated, it will damage one of the two relay Driver Chips (Part No. 3814) on the Power Center PCB. (These
chips can be replaced/see Page 4).

4 Two Speed Relay

Operation:

The Two Speed Relay operates in conjunction with a Standard Relay to operate a two speed pump/motor.
The Standard Relay is the On/Off relay and the T wo Speed Relay is the switching relay. Activating the relay coil for
the Standard Relay will complete the contact circuit between Line 1 and the motor common, and Line 2 and the Two
Speed Relay's Common. If the Two Speed Relay's coil wires are deactivated, its contacts make connection between
its Common terminal and its Normally Closed terminal and the motor runs at High Speed. When the Two Speed Relay
coil is activated, its contact makes connection between its Common contact and Normally Open contact, and the
motor switches to Low Speed.
If the Two Speed Motor is the filtration pump, plug the relay coil wires for the Standard Relay into the Filter Pump
Relay socket. Next, plug the Two Speed Relay's coil wires into Auxiliary 2. Finally, turn on DIP switch 2 to set circuitry

to two speed operation.

NOTE: Turn off power to system before moving DIP switches.

4 Light Dimming Relay

Operation:

The Controller signals the Light dimming Relay to turn ‘fully on”, “partially dimmed”, or “completely off” by sending a
specific number of pulses in a set period of time to the Light Dimming Relay . The circuitry of the Light Dimming Relay
(which requires 120 V AC to operate) then interprets the number and timing of pulses to determine whether the light should
be on, off, or dimmed.

The circuitry of the Light Dimming Relay is driven by the 120 V AC power from the circuit breaker for the light. Unlike
a Standard Relay , which receives a constant 24 VDC to its coil to hold the relay contacts closed (and which opens when that
voltage is removed), the Light Dimming Relay receives only signal pulses on the relay coil wires, and it is the circuitry on the
relay that actually turns on, off, and dims the light. Therefore, if the light is full on or dimmed, unplugging the relay coil wires
to the Light Dimming Relay will not turn off the light. The light will remain on as long as 120 V AC is supplied to the relay.

The Light Dimmer will operate slightly differently when activated from the Controller , Power Center or Spa Side
Switch.

From the Controller - When the auxiliary , which has been assigned to light dimming is pressed or programmed on,

the light will turn on to the brightness last set by pressing Back or Forward Buttons. Once on, the brightness may

be changed by pressing the Back or Forward Buttons. To turn it off, press the auxilliary button again.

From the Power Center override switch - Pressing the appropriate auxilliary button will turn the light on to the

brightness last set at the Controller or Spa Side Switch.

From the Spa Side Switch - If a button on the Spa Side Switch has been programmed to control a Light Dimmer

auxilliary , the first press of this button will turn the light on to full brightness, each additional press will dim the light

in 25% increments until the light is off.
Note: Besides needing a Light Dimming Relay installed, the auxilliary to operate the light dimming circuit must be assigned
at the Controller using the Menu button and moving to the SETUP Menu.

5 Jandy Valve Actuators

Operation:

One leg of a 24 V AC transformer secondary supplies voltage to the common terminal of a SPDT (single-pole,
double-throw) relay . The NC (normally closed) terminal of that relay is connected to the red wire of the JVA cord,
and the NO (normally open) terminal is connected to the white wire of the JV A cord. The completion of the circuit
is through the black (common) wire of the JV A cord.

When the coil of the SPDT relay is de-energized, voltage is supplied from one leg of the transformer secondary
to the common terminal of the relay and then down the red wire of the JV A cord to the toggle switch at the rear
of the JV A. The toggle switch then routes the voltage to either the lower microswitch (toggle in AUT O 1 position),
the upper microswitch (toggle in AUTO 2 position), or to neither microswitch (toggle in OFF position). If the voltage
is routed to the lower microswitch, and that microswitch is closed, the voltage passes through the motor to the
black wire and then back to the other leg of the transformer secondary to complete the circuit. The motor will then
rotate clockwise, turning the gear train (and ultimately the output shaft) until the lower cam comes in contact with
the lower microswitch, which opens the circuit and stops the motor. If the voltage is routed to the upper microswitch,
the motor rotates in the opposite direction until the upper cam lobe comes into contact with the upper microswitch,
which stops the rotation.

If the coil of the SPDT relay is energized, the voltage travels through the white wire to the toggle switch, which as
above, routes it either to the lower microswitch for clockwise rotation or upper microswitch for counterclockwise
rotation, with the voltage traveling back the black wire to complete the circuit.

The capacitor, which is wired in parallel with the motor, keeps the motor rotating in the correct direction and
insures the JV A rotates with the proper torque.

6 Sensor

Sensor

There is only one AquaLink RS temperature sensor. It is used for reading water, air and solar temperatures. The sensor is
described as a 10K RTD (10,000 Ohms - Resistive Temperature Detector) sensor, although the actual resistance will vary
with temperature. Below is a chart which shows how resistance changes as temperature changes.

ensor Resistance Range Chart:

At this temperature (degrees F) Resistance should be (Ohm s - X 1000)

50 F 19.9 K Ohm s (19,900 Ohm s)
60 F 15.3 K Ohm s
71 F 11.6 K O hm s
80 F 9.3 K Ohms
90 F 7.3 K Ohms
100 F 5.8 K Ohm s
104 F 5.3 K Ohm s

When measuring resistance across the sensor leads you must remove the sensor from the circuit.
Either disconnect both wires from the terminal bar or remove the terminal bar from the PCB. Then, to test
the Sensor, “0” out your meter and take reading across the sensor .

If a sensor fails, the Controller display will scroll on that sensor “Shorted” (i.e., little or no resistance), or “Open”
(i.e., no continuity).

NOTE: T emperature sensors from other Jandy Control Models cannot be used with the AquaLink RS.

8 Spa Side Switch

Spa Side Switch buttons send a momentary signal to the Power Center PCB. Each button sends a signal down
one wire with the circuit completed through the common wire. The operation of each button may be tested by
disconnecting the Spa Side Switch from the PCB and with a meter set to continuity measure between each button
wire and the common (black) wire, while holding the button down.

If any button on the Spa Side Switch is held down for more than 5 seconds, the AquaLink RS's microprocessor
considers this a shorted button and will ignore its signal. When the button is released or repaired, and a "shorted
circuit" no longer exists, the microprocessor will again recognize all buttons. The LED in the center of the switch will
be on solid when the spa is on, flashing fast when heating, and flashing slowly when in cool down mode.

Spa Side Switch

Black - Common wire
Red - LED wire
Blue - Button 1 wire
Brown - Button 2 wire
White - Button 3 wire
Green - Button 4 wire

Troubleshooting Steps

Remove the Spa Side Switch (6 pin) terminal bar from the printed circuit board.
Set your meter to read continuity (or resistance ).

• Ensure No Shorts
Measure between the black (common) wire and each of the button wires.
If there is continuity between any of the two (without depressing a button),
the switch is shorted; replace it.

• Ensure Continuity
Do this same test again except this time have a helper hold down the button
while you test for continuity . For example, measure between black and blue
while helper holds down button 1

TeleLink

Operation

There are two DIP switches on the TeleLink printed circuit board. DIP switch 1 allows the number of rings before
the TeleLink "picks up" to be set, and DIP switch 2 allows the access code to be changed from the factory default (62).
To change either setting, turn on the DIP switch for the item you wish to change (its LED will light). Next, go to a touch­tone telephone on the same phone line, lift the receiver and press the button or buttons corresponding to the desired
change (e.g., turn on DIP switch 2 and press telephone buttons 7 and 5 to change access code to 75). Finally , replace
the receiver and turn off the DIP switch. The new setting will now be turned into a memory chip.

The TeleLink printed circuit board has a number of LEDs on it. These LEDs help to identify problems with either the
telephone or the TeleLink (see diagram below). When the TeleLink is operating correctly, LED 2 will be on and LED 12
will be flashing. The four LEDs in the upper left hand corner (5, 6, 7 and 8) indicate whether the TeleLink is receiving the
correct pulse when a button is pressed on the telephone key pad. For example, pressing button 4 on a telephone should
light LED 7. Follow the chart to determine other button/LED operations.

The Diagnostics section of the AquaLink RS menu will indicate if the TeleLink is communicating.
