ISSUE | CAUSE | SOLUTION |
green LED always on | powered base. powered LEDholder. White light emission. | Fault-free operation |
Red LED continuously ON or White LED always OFF | White power LED in the LED-holder is not powered or maximum operating temperature was exceeded. | Switch off, wait for the red LED to turn off. Check the connection between base and LED-holder. Restore and switch back on. |
Red LED emits two equal flashes plus one pause. OR Intermittent white LED | The +5v of the control card in the LED-holder is missing. | Switch off, check connections between the base and the LED-holder, (also inside the LED-holder, green LED off). Restore and switch |
Fast intermittent Red LED (approx. 2 pulses per second) or Intermittent white LED | Input voltage exceeds the maximum voltage | Switch off. Reduce input voltage to below maximum voltage, (12vac + 30%), as measured on the base input connector, namely 15.6vac. Turn back on. |
Slow intermittent Red LED (approx. 1 pulse every 3 seconds.) OR Intermittent white LED | Input voltage is lower than the required voltage | Switch off. Increase input voltage to above minimum voltage, (12vac - 10%), as measured on the base input connector, namely 10.8vac. Turn back on. |
Intermittent Orange and green LEDs, 2 pulses plus one pause OR White LED with minimum intermittent value: | base or LED-holder output power supply +5v in short-circuit. | Switch off, eliminate short-circuit and turn back on. |
Steady Orange LED OR White LED off | White LED in short- circuit | Switch off, remove short-circuit and turn back on |
