Description
It is microprocessor controlled. When energized, the contact of the relay switches on. Charge led turns on while the SuperCap (electronic component that provides power supply when energy is cut off) is charged. By using the Mode control knob on the front side of the unit, 6 different operating time intervals can be selected.When the Supercap was full, Charge LED turns off and Ready LED which indicating the device is ready turns on. In this case, if energy of the device is turned off, it starts counting time and ready led flashes every 3 seconds. The output relay contact switches off at the end of the set time. If the device is de-energized while charge led still turns on (when the device is not ready yet), the charge led will flash every 3 seconds and After a while the relay contact is released without counting the true delay time.
