Scale Error Codes
16 = Angle sensor defective.
17 = Scale chip failure. The scale chip on the scale board is faulty.
For errors 16 and 17, unplug the bed and wait 5 seconds. Then plug the bed back in. If the error persists, replace the
scale board and calibrate the bed scale.
18 = Value of the foot left load cell is out of range: load cell may be disconnected, faulty or scale board is faulty.
19 = Value of the head right load cell is out of range: load cell may be disconnected, faulty or scale board is faulty.
20 = Value of the foot right load cell is out of range: load cell may be disconnected, faulty or scale board is faulty.
21 = Value of the head left load cell is out of range: load cell may be disconnected, faulty or scale board is faulty.
For errors 18 to 21, first verify load cell cables are plugged in and inspect for broken wires. If no visible problem is found,
swap two load cells on the scale connectors. This will help determine whether the load cell or the scale board is faulty.
If the error code changes with the load cell, the problem is with the load cell. Replace the load cell. However, if the error
code remains the same, then the problem is with the scale board. Replace scale board. In both cases, the bed has to
be calibrated.
