12.2 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 using the HART
®
communications.
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: -
Current output
Duration
< 1 mA
< 5 s
2 ± 0.2 mA
< 60 s
4 ± 0.2 mA
ongoing
Note: If gas is present, the unit will indicate a gas reading
Note: If the output reverts to 3 mA or < 1 mA, a Warning or Fault is present. Follow the instructions below to
investigate and clear a warning or fault (see Clear Faults or Warnings).
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 13 Maintenance, Bump Test for instructions.
