SC27P - Ozone Generator Drive Board LED Function
Figure 7-1B
LED Function
12V MAIN
POWER
When illuminated, this “Green” LED indicates that main power is supplied to the drive module up to the “on board”
fuse of the drive board.
XFMR
POWER
When illuminated, this “Green” LED indicates that 48V Buss power is available to the drive module transformer
(XFMR) from the “on board” fuse to the drive transformer.
OZONE
OUTPUT
The “Amber” ozone output LED will illuminate when ozone is being generated. The LED will also pulse as the
output increases or decreases with either the Manual Ozone Output Control or from a Remote 4-20mA signal.
FAULT When illuminated, this “Red” LED indicates that there is a fault with the drive module or the Ozone Reaction
Chamber. If this LED is illuminated, refer to the Troubleshooting Guide.
Notes: Upon startup, the fault LED will
remain illuminated for 30 seconds before ozone is produced. If the drive module goes to a fault condition,
the drive board will restart every 30 seconds. If the fault is not remedied the drive module will continue to
go into a fault mode. When the drive module is in fault mode ozone will not be generated.

Vacuum Break
Check the water level in the vacuum break, making sure it is above the flapper valve (see Figure 6-2). If water is not
pressing downward on the flapper valve it will open, causing a loss of vacuum. A loss of vacuum means ozone cannot
flow from the vacuum break, which in turn can cause an ozone leak.
Note: If the vacuum break must be refilled with
water disconnect the External Loop from the SC27P and shut down the system and follow the steps outline in
Chapter 6 “Installation Procedures – Pneumatic.” Then re-start the system by following the steps outlined in
Chapter 7 “Start-up and Calibration Procedures.”
