What this code means

This alarm occurs when the PLD device has a failure. The PLD device is used for both, the Passive Emergency Cell (see 4.3.3) and a Multiplexer on the Main Lifting/Lowering requests. This Multiplexer exits the Lifting and the Not Lifting level on two distinct addresses. When the Lifting and the Not Lifting outputs have the same Logic Level the PLD device has failed and this alarm occurs.

Applies to: ZAPI AC-0 SSL Sensored inverter (traction configuration).
