1. Alarm code 38 Internal fault
In case of alarm code 38, an additional code can be read via PC
Tool E-Products. Inform Grundfos Service for a detailed fault
remedy.
Alarm code Description
0 The serial port cannot be initialized. Serious hardware failure.
256 The power EEPROM data is defect or too old.
512 The control board EEPROM data is defect or too old.
513 Communication timeout reading EEPROM data.
514 Communication timeout reading EEPROM data.
515 The Application Orientated Control cannot recognize the EEPROM data.
516 Cannot write to the EEPROM because a write command is on progress.
517 The write command is under timeout.
518 Failure in the EEPROM.
519
Missing or invalid BarCode data in EEPROM 1024 – 1279 CAN telegram cannot be sent. (1027 indicates a
possible hardware failure.)
1281 Digital Signal Processor flash timeout.
1282 Power micro software version mismatch.
1283 Power EEPROM data version mismatch.
1284 Cannot read Digital Signal Processor software version.
1299 Option SW in slot A is too old.
1300 Option SW in slot B is too old.
1311 Option SW in slot C0 is too old.
1312 Option SW in slot C1 is too old.
1315 Option SW in slot A is not supported (not allowed).
1316 Option SW in slot B is not supported (not allowed).
1317 Option SW in slot C0 is not supported (not allowed).
1318 Option SW in slot C1 is not supported (not allowed).
1536 An exception in the Application Orientated Control is registered. Debug information written in LCP.
1792 DSP watchdog is active. Debugging of power part data Motor Orientated Control data not transferred correctly.
2049 Power data restarted.
2315 Missing SW version from power unit.
2816 Stack overflow Control board module.
2817 Scheduler slow tasks.
2818 Fast tasks.
2819 Parameter thread.
2820 LCP stack overflow.
2821 Serial port overflow.
2822 USB port overflow.
3072-5122
Parameter value outside its limits. Perform an initialization. Parameter number causing the alarm: Subtract the
code from 3072. Ex Error code 3238: 3238-3072 = 166 is outside the limit.
5123 Option in slot A: Hardware incompatible with Control board hardware.
5124 Option in slot B: Hardware incompatible with Control board hardware.
5125 Option in slot C0: Hardware incompatible with Control board hardware.
5126 Option in slot C1: Hardware incompatible with Control board hardware.
5376-6231 Out of memory.
