Internal control panel alarm
I5 - No voltage 0-1 (faulty voltage regulator
or short-circuit on accessories)
Check there is no short circuit in connection
0-1. If the problem persists, replace the
control panel.
I6 - Excessive voltage 0-1 (faulty voltage
regulator)
Replace the control panel.
I7 - Internal parameter error - value out-
side limits
Reset. If the problem persists, replace the
control panel.
I8 - Program sequence error Reset. If the problem persists, replace the
control panel.
IA - Internal parameter error (EEPROM/
FLASH)
Reset. If the problem persists, replace the
control panel.
IB - Internal parameter error (RAM) Reset. If the problem persists, replace the
control panel.
IC - Operation time-out error (>5 min or >7
min in learning mode)
Manually check that the gate wing moves
freely. If the problem persists, replace the
control panel.
IE - Power supply circuit fault Reset. If the problem persists, replace the
control panel.
IM - MOSFET alarm - motor 1 in short cir-
cuit or always ON
Reset. If the problem persists, replace the
control panel.
IN - MOSFET alarm - motor 2 in short cir-
cuit or always ON
Reset. If the problem persists, replace the
control panel.
IO - Interrupted power circuit - motor 1
(motor MOSFET open or always OFF)
Reset. If the problem persists, replace the
control panel.
IP - Interrupted power circuit - motor 2
(motor MOSFET open or always OFF)
Reset. If the problem persists, replace the
control panel.
IS - Error on current read circuit test - mo-
tor 1
Reset. If the problem persists, replace the
control panel.
IT - Error on current read circuit test - mo-
tor 2
Reset. If the problem persists, replace the
control panel.
IU - Error on voltage read circuit test - mo-
tor 1
Reset. If the problem persists, replace the
control panel.
IV - Error on voltage read circuit test - mo-
tor 2
Reset. If the problem persists, replace the
control panel.
