The EOG will automatically turn on and off by the  control PCB defined timing schedule. The EOG control board utilizes an on-
board diagnostic LED light to convey real-time performance status of the unit.  The control board within the EOG has several 
inputs and outputs. The following will address functions of the diagnostic LED, control input, and auxiliary outputs.

LED DIAGNOSTIC FUNCTIONS:

Green Light Blinking Slowly: 

Standby mode; unit is powered, pilot input is OFF.

Green Light Blinking Quickly: 

High voltage startup (up to 3 seconds).

Green Light Solid: 

High voltage is ON & stable; CD cell producing ozone.

Red Light Solid:

 Unstable operation; CD cell may need cleaning.

Green/Red Light Alternating Twice/Second: 

HV is ON, but operating current is low. If persistent, CD cell may need cleaning.

Red Light Flashing: 

NO or NC contacts are shorted. Remove short condition.

Orange Light: 

1-year timer has expired; clean CD cell, then reset timer by pressing red “alarm reset” button on PCB once.

Control Input:

The EOG PCB is activated to produce ozone when a pilot input signal is applied across “+” & “pilot” terminals.

Auxiliary Output Functions:

The NO/NC auxiliary outputs have a 3 second off-delay, after the pilot signal is shut off. These outputs are capable of 
outputting a maximum of 60mA @ 70°F and are intended to be used as a control circuit only. Attach positive wire to NO or NC 
output terminal, and negative wire to GND terminal to complete the desired circuit. See figure 1, on page 8 for auxiliary output 
locations.

Fusing:

The control PCB is equipped with automatically resetting on-board fuses. If these fuses trip, due to a short of the HV 
transformer, excessive load on the auxiliary output(s), remove excessive load/cause of short, and cycle main power on/off 
to reset. If the HV transformer is shorted, the LED indicator will stay solid red until condition is remedied. If either NO or NC 
output is active and experiences excessive load, the LED indicator will quickly flash red until condition is removed.
