P2 240 V AC Loss

What does 11219 mean?

240V AC input power was lost on port 2 while the drive was in an active state (e.g., MCS opening, closing, or closed). This causes the drive to cease operation.

• Tripped upstream circuit breaker or blown fuse on the 240V AC input line for Port 2.
• Loose or corroded wiring connection at the drive's 240V AC input terminals (L1/L2) for Port 2.
• Failure of an auxiliary control transformer or power supply providing 240V AC to the drive's control section (Port 2).
• Intermittent power supply to the drive's control section (Port 2) due to contactor chatter or faulty relay.
• Faulty 240V AC input voltage sensing circuit or its associated wiring for Port 2.

Click steps to track your progress.

1. 1

   Verify the status of all upstream circuit breakers and fuses protecting the 240V AC input to Port 2.

2. 2

   Measure the 240V AC voltage at the drive's L1 and L2 input terminals (Port 2) using a multimeter.

3. 3

   Inspect and tighten all power wiring connections at the 240V AC input terminals (Port 2) for looseness or damage.

4. 4

   Check the output voltage of any control transformer supplying 240V AC power to the drive (Port 2), if applicable.

5. 5

   Confirm the proper operation of input contactors or relays that supply 240V AC power to Port 2.
