X Rec PS Out Rng 634 Rectifier power supply out of range: The rectifier OIBBS
diagnostic subsystem has detected an out of range power
supply voltage on the internally generated supplies.
• Verify the STO system power supply/connection to the OIBBS.
• Cycle the control power.
• If the same fault still trips the drive, contact the manufacturer for spare parts of the power
supply and/or OIBBS for replacement.
X Rec PSD Fault 658 Rectifier power structure diagnostic fault: The safety control
system has detected a fault in one or more SGCTs. Incorrect
SGCT unit feedback was detected.
• Resolve all other faults first
• Ensure there are OIB2s are installed in the OIBBS, not the OIBs
• Ensure proper configuration setting of the SPS with drive hardware
• Check the LV wiring from the input device feedback
• Check the LV wiring/connectors to the OIBBS and ACB.
• Verify correct STO configuration settings
• Shut off all the power to the drive. Test the SGCTs according to the procedures in the User
Manual.
• Cycle the control power.
• If the same fault still trips the drive, contact the manufacturer for the OIBBS spare part(s)
for replacement.
X Rec S1 Stuck 640 Rectifier S1 stuck
: The rectifier OIBBS diagnostic subsystem
has detected a fault.
• Cycle the control power.
• If the same fault still trips the drive, contact the manufacturer for the OIBBS spare parts for
replacement.
X Rec S2 Stuck 641 Rectifier S2 stuck: The rectifier OIBBS diagnostic subsystem
has detected a fault.
• Cycle the control power.
• If the same fault still trips the drive, contact the manufacturer for the OIBBS spare parts for
replacement.
X Rec S3 Timeout 644 Rectifier S3 timeout: The rectifier OIBBS diagnostic subsystem
has detected a fault. A problem of timing function on the
OIBBS has been detected.
• Cycle the control power.
• If the same fault still trips the drive, contact the manufacturer for the OIBBS spare parts for
replacement.
X RecSTOInp Invld 643 Rectifier safety input invalid
: The rectifier OIBBS diagnostic
subsystem has detected an invalid control input state.
• Verify the wiring of the rectifier OIBBS.
• Cycle the control power.
• If the same fault still trips the drive, contact the manufacturer for the OIBBS spare parts for
replacement.
X Rec Temp Out Rng 635 Rectifier temperature out of range: The rectifier OIBBS
diagnostic subsystem has detected an out of range
temperature.
• Verify the airflow in the low voltage control compartment.
• Shut off the control power to let temperature drop off.
• Cycle the control power.
• If the same fault still trips the drive, contact the manufacturer for the OIBBS spare parts for
replacement.
X Rec WtchDg T Out 633 Rectifier watchdog timeout: A failure of the rectifier OIBBS
diagnostic subsystem was detected.
• Verify all the connections for OIBBS, OIB2 on rectifier side.
• This fault will only reset upon cycling control power.
• Cycle the control power, and if the same fault still trips the drive, contact the manufacturer
for spare parts of the OIBBS, OIB2 and/or the connections for replacement.
