    2 mA The tolerance on the nominal current output value is ± 0.2 mA. During Warning status, the Searchpoint Optima Plus will continue to monitor gas, and will revert to Gas Reading status if a gas reading is detected. If a Warning is indicated, schedule maintenance to investigate and rectify the cause. If left unattended, the unit is likely to enter Fault status, when it will be offline.

  • Page 31: Commissioning

    Note: If the output reverts to 3 mA or < 1 mA, an active or latched Warning or Fault may be present. If this happens re-cycle the power. If the Warning or Fault persists, please refer to Chapter 14 Troubleshooting. Searchpoint Optima Plus is factory calibrated and it is not necessary to calibrate or gas test it during commissioning. However if local regulations or site practices require that a gas test is done to check that the unit is functioning, please see Chapter 7 Maintenance, Bump Test for instructions.
