LOGIC FAILURE #1

What does 1019 mean?

A logic failure of type #1 has occurred in the motor controller (codes 1019, 2019, 3019). This indicates an internal control logic error, preventing correct operation. The specific lift reaction is controller dependent.

• Internal controller logic processing error.
• Corrupted program memory or runtime data.
• Hardware fault affecting logic circuits or CPU functionality.

Click steps to track your progress.

1. 1

   Verify main AC/DC supply voltage to the motor controller input terminals against nominal specifications and stability.

2. 2

   Check and compare current operational parameters and configuration settings of the motor controller against the documented system backup or factory defaults.

3. 3

   Inspect and verify the operational status of critical inputs such as encoder feedback, limit switches, and safety circuit signals via the controller's diagnostic interface.

4. 4

   Perform a controlled power cycle of the motor controller after safely stopping the elevator, observing for recurrence of the error.
