PROBLEM/SYMPTOM
POSSIBLE CAUSE
SOLUTION
Ozone Output LED’s are not
- The remote 4-20mA control signal is not
- Check for loose wires or connections
responding to the remote 4-20mA
sensed by the 4-20mA control circuit
- See “Installation Procedures – Electrical”
control signal
- Check 4-20mA controller operation
Ozone Generator “Drive 1” and/or - No power to drive module from power supply
- Check main power to unit
“Drive 2” LED(s) are not illuminated
- Test voltage from power supply
to drive module (see “Appendix –
Drive Module Input Voltages”)
- Check for loose wires or connectors
- If drive module “Main Power” LED(s) not
- Test voltage from power supply to
illuminated, the “XFMR Power” LED will
drive module (see “Appendix – Drive
not illuminate
Module Input Voltages”)
- Blown drive module “on board” fuse
- Replace “on board” fuse
- Drive board is in “Fault” mode
- See Troubleshooting, “Fault” LED
Ozone Generator “Fault 1” and/or - Upon start-up the “Fault” LED will be “ON” - Wait for the start-up to finish
“Fault 2” LED(s) illuminated and for 30 seconds, this is normal
Drive Module - “Fault” LED(s)
- Loose wire harness connection from the drive - Check all wires and connectors
illuminated
board to the drive transformer
- Failed drive board
- Replace drive board
- Failed drive transformer
- Replace drive transformer
- Broken dielectric
- Replace dielectric
- Water in ozone reaction chamber
- Clean dielectric and replace O-rings
- Excessive dirt or debris in the ozone reaction - Clean dielectric and replace O-rings
chamber
- Loose or disconnected High Voltage lead to
- Attach High Voltage lead to transformer
transformer
- High temp limit
- If the temperature with in the SC27P
system is greater than 150˚ F; the drive
modules will go to Fault mode.
Drive Module - Main Power - No power to drive module from
- Check main power to unit
“Green” LED(s) not illuminated
power supply
- Test voltage from power supply
to drive module (see 'Appendix' –
Drive Module Input Voltages)
- Check for loose wires or connectors
Drive Module - Transformer (XFMR) - If drive module “Main Power” LED(s) not
- Test voltage from power supply to
Power, “Green” LED(s) not
illuminated, the “XFMR Power” LED will
drive module (see “Appendix–Drive
illuminated
not illuminate
Module Input Voltages”)
- Blown drive module “on board” fuse
- Replace “on board” fuse
- Drive board is in “Fault” mode
- See Troubleshooting, “Fault” LED
Drive Module - Ozone Output,
- If the Transformer (XFMR) Power LED is not - Check all wires and connectors
“Amber” LED(s) not illuminated
illuminated, the “Ozone Output” LED will not
illuminate
- The Manual Ozone Output is turned
- Turning the Manual Ozone Output knob
down to 0%
clockwise will increase ozone output
percentage and the “Ozone Output” LED
will begin to illuminate (see “Installation
Procedures – Electrical”)
- Drive board is in “Fault” mode
- See Troubleshooting, “Fault” LED
Drive Module - “Ozone Output”
- The remote 4-20mA control signal is not
- Check for loose wires or connections
LED(s) not responding to the remote sensed by the 4-20mA control board
- Check electrical installation procedures
