Abnormal Displays at Power-Up
The payload meter performs several internal memory system checks every time it powers-up. In case of error, the
operator gauge may display an error code when power is applied to the PLMIII system.
Er:01 - Bad Truck Configuration error indicates that the meter encountered an error while reading the current truck
configuration record from memory.
Er:02 - Bad Calibration Record error indicates that the meter encountered an error while passing messages
between the microprocessors on the circuit board.
Er:03 - Interprocessor Communications error indicates that the meter encountered an error while passing mes-
sages between the microprocessors on the circuit board.
To resolve these errors:
• If these errors persist after reprogramming, the primary and secondary processors then the payload meter
must be replaced.
