INCORRECT START

What does 1079 mean?

The motor controller (codes 1079, 2079, 3079) has detected an incorrect or unsafe start condition. This typically means startup prerequisites were not met or an unexpected command was received. The specific lift reaction is controller dependent.

• Motor enabled without proper safety interlocks engaged.
• Start command received unexpectedly or out of sequence.
• Internal logic error during the startup sequence.

Click steps to track your progress.

1. 1

   Verify the status of all elevator safety chain inputs (e.g., door locks, emergency stops, pit switches) using the controller's diagnostic interface to confirm they are closed.

2. 2

   Inspect the input signals for car calls, landing calls, and inspection mode commands via the controller's diagnostics to identify any unintended or stuck active signals.

3. 3

   Check all control and safety circuit wiring connections at the controller, terminal blocks, and safety devices for looseness, corrosion, or damage.

4. 4

   Verify the motor controller's operational parameters, including start-up sequence and specific elevator configuration, against the system documentation.
