Power connector: 5.5 x 2.1 mm DC power connector
Sensor Interface: 4-core plug (Ø12)
Output Interface: core plug (Ø12)
Relay Output: normally open type contacts largest AC250V, 10A
Analog output: 0-5V and 4-20mA can not be used at the same time need to be specified when ordering, 0-5V output is non-positive and negative short-circuited
Show: four red LED display;
Run: run light, normal working hours flashes per second; ALARM: The alarm indicator, the ozone concentration is greater than the set alarm concentration Always, normally open relay closes.
Alarm point for the method:
1: Press and hold the SET key for more than 3 seconds, running lights and alarm indicator light, into the set, displays the current alarm value;
2: Press : alarm value increases, the value decreases ,Press alarm; Press and can be quickly adjusted;
3: adjustment is completed, press the SET button to return to run the interface, run the light is blinking;
Fault information:
1: ALARM light: ozone concentration values greater than the set alarm value, the concentration of ozone gas automatic recovery
2: ERR: sensor failure, check the connection is normal, or contact the manufacturer to replace the sensor
3: Display OVER: ozone concentrations exceeding the sensor range
