Crestron CSA-PWS10S-HUB Power Supply for Crestron Shade Motors
Operation
Once the power supply is mounted, wired, and powered up, a diagnostic test of the device and wiring should be
performed. During the diagnostic test the power supply identifies connected shades and tests the wiring of the
connected shades.
Hold down the TEST button for 2 seconds to enter Test mode. The MSG LED blinks to indicate that the power
supply is in Test mode.
During Test mode, the LED for the associated connection blinks to indicate the status of the connected shade. The
LED blinks in a #-# format. The first # indicates the number of consecutive LED blinks, the dash represents a short
pause, and the second # indicates the second number of consecutive LED blinks. The pattern repeats until the error
is cleared or the TEST button is pressed. Refer to the following table for error definitions.
LED Blink Patterns for Test Mode
BLINK PATTERN ERROR
1-1 Broken Wire – Y
1-2 Short 24 V to Y
1-3 Short GND to Y
2-1 Broken Wire – Z
2-2 Short 24 V to Z
2-3 Short GND to Z
3-1 Short Y to Z
3-2 Broken Wire – Y or Z
Solid No Error
Off No Devices Detected
NOTE: A short to 24 V may be reported as a short to GND on long cable runs.
NOTE: A false short Y to Z may be reported if a termination resistor is implemented on Cresnet. Cresnet does not
require termination resistors.
NOTE: Not all broken wire conditions can be detected. A broken wire can only be detected in situations where
there is intermittent communication.
The MSG LED also blinks to indicate an error situation on the device. The LED blinks using the same #-# format
described above. Refer to the following table for error definitions.
LED Blink Patterns for MSG LED
BLINK PATTERN ERROR
1-1 Com Issue Master error occurs when the master branch is held low for
more than 10 character times.
1-2 Com Issue Branch error occurs when any non-master branch is held low
for more than 10 character times.
1-3 Com Issue Master and Branch error occurs when the master branch and
any non-master branch are held low for more than 10 character times.
2-2 Blown fuse(s)
Press and hold MASTER UP or MASTER DOWN to test all connected shades. After the button is pressed for
2 seconds the power supply disconnects from the control system (if connected) and sends a raise or lower command
to all connected shades. The MSG LED blinks to indicate that the power supply is sending the raise or lower
command to all connected shades.
NOTE: The control system stays disconnected for 10 seconds after the last MASTER UP or MASTER DOWN
button press.
