read in the range indicated on the “Ozone Generator Air Flow” line of the “Pneumatic Operating Parameters”
chart, Figure 7-2.
Note: When the system is under normal operation, the “Air Prep System Air Flow” set
point will drop from the initial setting due to the system being under backpressure.

NOT
RE-
ADJUST THE AIR FLOW GAUGE ADJUSTMENT VALVE.
Step 10:
Perform a final check of all air connections from the SC27P to the ozone injector manifold. Repair leaks as
required. Check all system water connections, including the ozone injector manifold, vacuum break and
contact vessel. Repair leaks as required.
Note: The check valve at the ozone injector manifold may make a
humming noise. This is normal.
Step 11:
Reconnect the External Loop connector to the ozone generator.
Note: The Ozone LED(s) will not illuminate
and ozone will not be produced until the External Loop has been replaced.
Step 12:
Observe indicating LED(s), on the control panel of the SC27P and adjust the manual ozone output control
knob to desired level setting. See Figure 7-1 A-C for proper LED function and Appendix-Section A for
location of the LED’s.
SC27P – Control Panel LED Function

LED
Function
SC27P LED Display
System Power
Main Power is “ON” to the SC27P, when LED is Illuminated
Pressure
The SC27P has sufficient pressure, when LED is Illuminated
Motor Control
Interlock (MCI)
The MCI is energized, when LED is illuminated
External Loop
The External Loop has continuity through it when the LED is
not
illuminated, which indicates ozone is being produced. The External
Loop
does not
have continuity, when the LED is illuminated, which
indicates no ozone production.
Manual Control
Ozone output is being controlled by the Manual Ozone Output Control,
when LED is illuminated
Remote 4-20mA
Control
Ozone output is being controlled by an External 4-20mA Control signal,
when LED is illuminated
Ozone Output
Level
The ten LED’s represent 0-100%, minimum to maximum ozone output.
Each LED is equal to 10% output. These LED’s can be adjusted with
the manual ozone output control knob located on the control panel of
the SC27P or automatically with a remote 4-20mA control signal.
Drive 1 and Drive
2 - Power
Power is being sent to the high voltage Drive board, when the LED is
illuminated
Drive 1 and Drive
2 - Fault
When illuminated, this 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
and the ozone output LED’s will not be illuminated. 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.
