Commissioning; First Time Switch On - Honeywell Searchpoint Optima Plus Operating Instructions Manual

MAN0905_Issue 7_07/17
Read this chapter if the SHC1 Handheld Interrogator or the HART
are not being used.

6.1 First Time Switch On

Note: Searchpoint Optima Plus is supplied calibrated and ready for use. It does not require calibration
during commissioning.
Note: During commissioning the 4-20 mA output can be monitored either at the control room or locally
with a multimeter. When connecting or disconnecting a multimeter, power off the Searchpoint Optima Plus,
otherwise the unit will indicate a latched warning that the 4-20 mA loop was broken. If this occurs it can be
cleared by re-cycling the power.
1. Before applying power to the unit, ensure that the field wiring is correct and all electrical connections
are in accordance with Section 4.
2. Apply power. Check that the supply voltage to the Searchpoint Optima Plus is between 18 and 32 V.
3. Monitor the 4-20 mA output during the start up sequence, which should be as follows: -
Note: If gas is present, the unit will indicate a gas reading.
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.
