Description
After the start flashing signal, the eSTL electronics flashes a total of 16
times.
If, during the 2nd, 13th, 14th or 15th flash, both red LEDs also light up,
the power supply (voltage or frequency) was out of tolerance for more
than 10 seconds (frequently during alternator operation, for example).
After the start flashing signal, the eSTL electronics flashes a total of 16
times.
If the power supply is OK and a different blink code applies, an internal
error of the eSTL electronics has been detected
After solving the problem: Reset eSTL, press the reset button for three
seconds.
Blink codes flash more than 8 times: This is most often due to the power
supply to the unit (e.g. connection to generator)
