How can I determine what the PM5500 Front panel Status code means?
The meter's front panel status code is displayed in hexadecimal without a full explanation of what the hexadecimal value represents. The customer would like an explanation as to what this status means.
PM5500 series (PM5560, PM5563)
Use the following instructions to decipher the status code. In this example, the status reads "0021 hex".
- Convert the hexadecimal value to binary.
||0000 0010 0001
- Determine which Bits are a "1" or high.
In this example, Bit 01 and Bit 06 are high.
- Apply the Bitmap found in the Modbus Register List at Register 20003.
Bit 01 = Summary ( on if any other bit is on - Maintenance Icon shown on HMI )
Bit 02 = RAM Failure
Bit 03 = NVRAM Failure
Bit 04 = RTC Failure
Bit 05 = Calibration Failure
Bit 06 = Clipping Detected
Bit 07 = Over-Running Energy Pulse Output
Bit 08 = Inp Mtr Diag Rate Exceeded/Backup RAM failure
Bit 09 = Lang File Mis Match
Bit 10 = Lang String Mis Match
Bit 11-16 Not Used
Therefore, this device appears to be having a clipping issue, and the customer must evaluate the voltage and current inputs to confirm they are within the meter's specification.
