   TIME MONITORING FOR AIR DISINFECTION SYSTEMS
----------------------------------------------

 **For a permanently stable disinfection performance, we recommend equipping the systems with a lamp life monitoring system.**

The OTC evaluation unit monitors the service life by summing up the operating hours of the UV lamp. The service life status is indicated by LEDs

The system works as a normal operating hours counter. When the operating voltage is applied, the counter starts to run. Each time it is switched on, the so-called "startup" procedure is carried out first. The red, yellow and green LEDs light up one after the other for 1 second. This serves to check the function of the LEDs. The counter can also be reset by interrupting the procedure.

The monitoring unit was designed with its display in the form of a traffic light. For example, if the current number of operating hours t < 9,500 h, the green LED lights up. If the current number of operating hours exceeds this threshold, the yellow LED is activated. If the second threshold is exceeded (>10,000 h), the red LED is activated.

It is installed behind the front panel of the switch box.
