Cardin Motor Error Codes: Reading Them to Diagnose the Fault

When a Cardin motorisation refuses to work, it tells you: through a sequence of LED flashes or a code on the control unit's display. Knowing how to read these signals avoids replacing parts at random.

The most common error families

• Safety errors: misaligned, dirty or short-circuited photocells, triggered safety edge – the gate refuses to close. This is the number-one cause of reported "breakdowns".
• Force errors: obstacle detection or motor overload – dirty rail, frost, or a leaf rubbing.
• Encoder errors: the unit no longer "sees" the gate's position – wiring or sensor at fault.
• Power errors: insufficient voltage, flat back-up battery or tired transformer.

The diagnostic method

1. Count the flashes precisely (or note the displayed code) and when the error occurs.
2. Check your control unit's manual table: each code points to a specific circuit.
3. Start with the simple checks: clean the photocells, inspect the terminals, check the rail.
4. Cut the power for 30 seconds to clear a transient error, then test.

When the board is at fault

An error that returns after a reset, despite clean safeties and a free-moving gate, points to the electronic board or the motor. These parts can be replaced: our technicians diagnose and repair Cardin and all other motorisations throughout Île-de-France, with a free quote before work.
