12.3 – OVERHEATING INDICATION
The 'FC' LED rapidly flashes to warn that the power amplifier has disarmed
due to overheating of the heat sink or environment. The operator will only be
able to operate again if the temperature decreases to less than 100ºC (212° F).
12.4 – LACK OF EEPROM INDICATION
The 'SN' LED flashes twice whenever the memory is absent.
12.5 – EEPROM WITH INVALID DATA INDICATION
The 'SN' LED flashes three times whenever the memory is present but has
a content which the microcontroller does not identify as a Valid Transmitter
Code.
12.6 – OPEN LIMIT SWITCH INDICATION
The 'FC' LED flashes whenever the gate is in an open limit switch area.
12.7 – CLOSED LIMIT SWITCH INDICATION
The 'FC' LED remains lit whenever the gate is in a closed limit switch area.
12.8 – LOAD ON THE CAPACITORS INDICATION
The 'BUS' LED indicates there is a load on the capacitors of the power amplifier.
Caution: One must not touch the power area (capacitors area) of the board
whenever this LED is lit, even after the inverter has been disconnected from
the power supply!
12.9 – COMMANDS INDICATION
The 'FA', 'BOT', 'FF', 'ABR' and 'FEC' LEDs indicate that the control unit is re-
