What to do if Honeywell Searchpoint Optima Plus Gas Detectors shows a warning for a bad 4-20mA loop?
- W
  wolfstevenJul 27, 2025
  If your Honeywell Gas Detectors unit shows a warning of a bad 4-20mA loop, which can latch the 4-20 mA output, it could be due to an error greater than ±0.5 mA in the analogue output. If this occurred while connecting/disconnecting a multimeter, re-cycle the power or reset to clear the latch. Also, inspect the 4-20 mA loop connections and cabling, and ensure the loop resistance is less than 600 ?. If the supply voltage is between 18 to 20 Vdc in current source mode, the maximum loop resistance is 500 ?.

  If your Honeywell Gas Detectors unit displays a fault for a bad 4-20mA loop, which latches the 4-20 mA output, it means the unit can't generate the correct current output for a gas reading. To resolve this, check the 4-20 mA loop connections and cabling. Also, verify that the loop resistance is less than 600 ?. If operating in current source mode with a supply voltage of 18 to 20 Vdc, ensure the maximum loop resistance is 500 ?. You can also try re-cycling the power or performing a reset to clear the latch.

Why Honeywell Searchpoint Optima Plus displays warning / fault negative gas reading?
- A
  Adam AyalaAug 7, 2025
  If your Honeywell Gas Detectors unit is showing a warning or fault related to a negative gas reading, it could be due to a negative offset. Ensure that the optics are clean and dry. If the unit is in a very damp or condensing environment, consider adding extra protection. Also, check for the presence of interferent gases like acetylene or ammonia, and review any temperature limit exceeded warnings or faults. Finally, clean the optics, ensure they are dry, and re-zero the unit in a gas-free environment.

What to do if Honeywell Gas Detectors displays warning / fault bad 24V supply?
- M
  Michael ClarkAug 12, 2025
  If your Honeywell Gas Detectors unit is showing a warning or fault related to a bad 24V supply, it means the 24 V supply is outside of operating limits. Make sure the supply voltage at the unit is between 18 V and 32 V. If the voltage is within range, try re-cycling the power or performing a reset to clear the latch.

How to resolve warning temperature limit exceeded on Honeywell Gas Detectors?
- K
  Kristine SteeleAug 16, 2025
  If your Honeywell Gas Detectors unit's temperature exceeds the warning limit, take steps to protect it from extreme heat or cold. Consider re-locating the unit to a more suitable environment. You might also explore installing the unit in a sampling system as an alternative.
