What to do if Honeywell Recording Equipment shows FAILSAFE error?
- S
  Shelby OconnorAug 19, 2025
  The FAILSAFE error message appears when the Honeywell Recording Equipment enters failsafe mode, often due to a failed power-up or background test when control is enabled. To resolve this, use the 'Device Status' check to identify the specific reason for the failsafe indication. Then, find the corresponding error message and follow the recommended solutions for that particular error.

Why does my Honeywell Recording Equipment display EE FAIL?
- K
  Karina BeltranAug 21, 2025
  The EE FAIL error on your Honeywell Recording Equipment indicates an inability to write to nonvolatile memory. This often occurs when a parameter change is not accepted. To fix this, verify the accuracy of the parameter you are trying to change and re-enter it. You may also try changing a different configuration setting.

What to do if Honeywell DR4500A Recording Equipment shows RAM TEST error?
- A
  Aaron GreenAug 23, 2025
  If your Honeywell Recording Equipment displays a RAM TEST error, it indicates a RAM failure. First, try cycling the power to the device. Then, check the 'Device Status' to see if the error has cleared. If the error persists, the main printed circuit board may need to be replaced.

What does it mean when Honeywell DR4500A Recording Equipment displays PV LIMIT?
- J
  Jeffrey KnightAug 26, 2025
  A PV LIMIT error on the Honeywell Recording Equipment means the Process Variable is out of the acceptable range (±10% of range). Ensure the pen input configuration is correct and check if the displayed PV value exceeds the input limits.

What to do if Honeywell DR4500A displays CNFG ERR?
- S
  Steven JohnsonAug 30, 2025
  If your Honeywell Recording Equipment displays CNFG ERR, it means the configuration data is in error. To fix this, carefully check all configuration prompts for accuracy, referring to the configuration section for valid selections and limits. Change any configuration item, check 'Device Status' to see if CONFTEST = PASS, then return the configuration item to its original value.

What does CAL TEST error mean on Honeywell Recording Equipment?
- V
  vhaysSep 3, 2025
  The CAL TEST error on your Honeywell Recording Equipment indicates that the working calibration constants are in error. To resolve this, try changing to a different input type. Then, check the 'Device Status' to see if FACT CRC = PASS. If it passes, return to the original input type. If it fails, perform a field calibration.

What does RV LIMIT mean on Honeywell Recording Equipment?
- M
  Maurice SmithSep 6, 2025
  The RV LIMIT error on Honeywell Recording Equipment indicates that the result of the formula (RV = INP2 X RATIO + BIAS) is beyond the range of the remote variable. Ensure the input signal is correct, and verify the ratio and bias settings. You can also go to CONTROL prompt REMOTE SOURCE and change REMOTE to 1LOCAL.

What does CAL1 ERR mean on my Honeywell DR4500A Recording Equipment?
- C
  clarkrachelSep 8, 2025
  The CAL1 ERR on your Honeywell Recording Equipment indicates a working CAL TEST failure related to Control 1, Input 1, or Input 2. To address this, try changing to a different input type. Then, check the 'Device Status' to see if FACT CRC = PASS. If it passes, return to the original input type. If it fails, perform a field calibration of Control Output #1, Input 1, or Input 2.

What does CAL2 ERR mean on Honeywell DR4500A?
- D
  dawn23Sep 12, 2025
  The CAL2 ERR error on your Honeywell Recording Equipment indicates a working CAL TEST failure related to Control 2, Output. To resolve this, perform a field calibration of Control Output 2.
