What to do if I get a MISSING SLAVE MODULE error on my Bailey Control Unit?
- T
  tonyajohnsonAug 16, 2025
  If you're encountering a MISSING SLAVE MODULE error, it could be due to a mismatch between the address set on the address switch (S1) and the MFP configuration. Try removing the module and changing the setting of S1 to match the MFP configuration. Another potential cause is that the slave expander bus isn't properly connected between the MFP and slave module. Ensure the bus connection is secure on the MMU backplane.

What causes a Bus fault timer error (time-out) in Bailey Control Unit, and how can I fix it?
- C
  Christy ArnoldAug 20, 2025
  A Bus fault timer error (time-out) may occur due to a slave expander bus clock failure. Check the MFP module for proper operation. Also, verify that the dipshunt is correctly installed in the slave expander bus socket on the MMU backplane between the MFP and slave module, as an improperly installed dipshunt can also cause this error.

How to enable a slave module on a Bailey Control Unit?
- U
  ucraneAug 22, 2025
  If the slave module isn't enabled, it might be because the address set on S1 doesn't match the address in the MFP configuration FC 79 spec 1. Change the address on S1 to align with FC 79 spec 1, or modify the address in FC 79 spec 1 to match S1. Also, ensure the dipshunt is properly installed (no bent pins) in the slave expander bus socket on the MMU backplane between the MFP and slave module. Finally, verify that FC 79 is correctly configured in the MFP configuration.

Why am I getting an ANALOG INPUT REFERENCE ERROR on my Bailey Control Unit?
- J
  jenniferwilliamsAug 26, 2025
  An ANALOG INPUT REFERENCE ERROR can occur if the QRS reference voltages (1 VDC and 5 VDC) used to calibrate the analog input zero offset and gain are not within tolerance. Check the analog inputs to ensure their voltages are within QRS specifications (1 to 5 VDC). Also, verify that the analog inputs' common mode voltage is within QRS specifications ( ±10 VDC).

What to do if there is no power to the slave module on Bailey Control Unit?
- R

  If there's no power to the slave module, ensure the module is fully inserted into the MMU, with the faceplate flush and the captive retaining screws latched.

What causes 'Analog Input Reference Error' in Bailey I/O Systems, and how to fix it?
- M
  Michelle LarsenAug 31, 2025
  The 'Analog Input Reference Error' in Bailey I/O Systems occurs when the I/O module reference voltages (1 VDC and 5 VDC) used for calibrating the analog input zero offset and gain are out of tolerance, or if the analog inputs themselves are not within tolerance. To resolve this, check that the analog input voltages are within the specified range (1 to 5 VDC) and that their common mode voltage is within specifications (±10 VDC). If the analog inputs are correct, consider replacing the CIS or QRS module.

Why Bailey I/O module is not enabled?
- A
  Alison ThomasSep 3, 2025
  There are several reasons why a Bailey I/O module might not be enabled: * The address set on address switch S1 does not match the address in MFP configuration FC 79, spec S1. To fix this, change the address on address switch S1 to match FC 79, spec S1, or vice versa. * The dipshunt is not properly installed between the MFP and I/O module. Ensure the dipshunt is correctly installed (with no bent pins) in the I/O expander bus socket on the MMU backplane between the MFP and I/O module. * The MFP configuration is incorrect. Verify that FC 79 is correctly configured in the MFP configuration.

What to do if Bailey I/O Systems show 'Missing Slave Module Error'?
- W
  Whitney WheelerSep 6, 2025
  If you receive a 'Missing Slave Module Error' on your Bailey I/O Systems, it could be due to a disconnected I/O expander bus between the MFP and I/O module. To solve this, verify the bus connection on the MMU backplane.

What causes a bus fault timer error (time-out) in Bailey I/O Systems?
- A
  Andrew HigginsSep 9, 2025
  A bus fault timer error (time-out) in Bailey I/O Systems can occur if the dipshunt is not installed between the MFP and I/O module. To resolve this, verify that the dipshunt is installed in the I/O expander bus socket on the MMU backplane between the MFP and I/O module.
