AquaPalm Quick Troubleshooting Guide
The AquaLink RS AquaPalm will stop communicating
anytime interference (such as a 900 MHz device)
prevents a valid signal transmission. When
communication is lost the AquaPalm Handheld
Remote will lock on the startup screen until a
good link is again achieved, usually within a few
seconds. If communication is not reestablished
within a few seconds or if this happens often, use the
troubleshooting information in the following table
for suggestions.
Symptom
Power Center override switches
operate when in Service or Time
Out Mode, but the AquaPalm
Handheld Remote is completely
dead (no backlight on or display).

Problem
Dead batteries in the AquaPalm
Handheld Remote.
AquaPalm is not communicating
with the power center PCB.
1. Damaged or improperly
installed PPD.
2. Wrong PPD.
3. Damaged power center PCB.
Wrong PPD chip installed at the
power center PCB.
Microprocessor locked.
AquaLink RS does not display
correct time and date.
No communication between
AquaPalm Handheld Remote
and Power Center J-box.
Possible Solution
Replace batteries.
Check the two center wires (black & yellow) of the
four conductor cable to the transceiver
J-box. Also check the installation of the PPD on
the power center PCB. If the PPD is not seated
correctly the system will not communicate.
1. Check alignment of the PPD.
2. Make sure that the PPD is for an AquaPalm.
3. If PPD is installed correctly, replace the power
center PCB.
Ensure that the PPD revision number is the correct
revision required for the application.
Turn off power to the system. Disconnect battery
at the Power Center and turn on power. Reconnect
the battery and reset time and date.
At the AquaPalm Handheld Remote, set correct
time and date. Check battery level. If LOW
BATTERY is displayed, replace battery at the
Power Center to ensure correct time and date are
maintained.
Change the Frequency Channel. See Section 3.4.
Move the Transceiver J-box closer house or under
an eve.
