5 Configuration
5.1 General
The OELD has several configurable parameters, which are set using a mobile device running the OELD app. Essentially, these are the
threshold for local alarm indication, mA input level settings, Remove RS485 communication settings, behaviour of the green light
and display settings such as full scale range, measurement unit and gas name.
5.1.1 Threshold for Local Alarm Indication
The gas reading at which the the OELD indicates an alarm (flashing red lights) can be set between 5 and 65 % FSD. The default
setting is 20 % FSD.
Note
This setting is local to the OELD and applies only to the red lights in the OELD backlight. Changing the level will have no effect
on alarm levels configured in the sensor, or in the control room.
Note
Guidance for setting alarm levels appropriate for the application can be found in IEC/EN 60079292 and/or other regional and
local publications.
5.1.2 mA Input Level Settings
The sensor transmits a mA output in relation to the measured gas value. Also the mA output is used to provide an indication of the
status of the sensor which can include warning, fault and inhibit. The mA input to the OELD can be configured to match the mA
output profile of the sensor to control the OELD backlight function and show messages on the OELD display. The factory settings
for Searchpoint Optima Plus and Searchline Excel are given in the table below.

Note
*Searchpoint Optima Plus with HART® requires a minimum of 1 mA flowing in the current loop for HART® communications to
be maintained. It is possible to set the mA level in the Searchpoint Optima Plus for fault to 1 mA, however this may affect the
reliability of the HART® communications.
To ensure correct reporting of the gas detector status (fault, inhibit, warning and over-range), it is essential that the mA input ranges
are chosen to match those of the connected gas detector. Allow for a separation of at least 0.1 mA between each of the ranges.

Configuration of the OELD is achieved through use of a mobile device running the OELD app. There is no local interface to configure
the OELD.
The configuration process involves connecting to the OELD unit via the Bluetooth® (BLE) interface of a suitable smart phone or
tablet. During the connection, the blue light of the OELD will indicate different states. Once the connection has been successfully
established and if the sensor status is normal, the OELD blue light will be lit solid blue to indicate this. Connect the mobile device to
the OELD as follows:
1. Locate the icon for the OELD App on the mobile device and tap on it to start the app
2. Log into the OELD App by entering the registered User ID and Password
3. Search for nearby OELD units
4. Select the desired OELD from the displayed list
5. The backlight of the OELD will flash blue, confirming your selection from step 4
6. Once the user has confirmed the unit, the connection process will complete
7. The OELD App will display information from the OELD on the main status screen.
For more details on the connection procedure refer to section 6.2 Bluetooth® Communication.
Once the OELD is connected to the mobile device, the user can configure the OELD via the menu system of the app. For more
details on the operation of the mobile application, refer to section 7 OELD Mobile App.
After all operations have been completed, simply terminate the connection from the main screen of the app so that other mobile
devices can connect to it.

7.6 Calibration
The OELD App allows a user to calibrate the Searchpoint Optima Plus or Searchline Excel. Note that this feature is not available for
other gas detectors or sensors that may be used.
Caution
Searchpoint Optima Plus is factory calibrated and does not require routine calibration. In most cases, a re-zero will correct any
inaccuracy in the gas reading. It is strongly recommended that a span calibration is not carried out.
After establishing a connection between the mobile device and the OELD, tap on the Calibrate button on the main screen of the
OELD App.
1. Ensure that the gas detector is in fresh air and tap on the Zero button to start the zero calibration process
2. The OELD App will automatically inhibit the gas detector and initiate the zero calibration.
3. After a successful zero calibration has been completed a span calibration may be performed. Tap on the Span button to perform
a span calibration and complete steps 4 and 5 below. Otherwise tap on Exit Without Span to exit and ignore steps 4 and 5.
4. Apply calibration gas to the Searchpoint Optima Plus
5. Follow the on-screen prompts and wait until span calibration is complete
Refer to the Searchpoint Optima Plus or Searchline Excel Technical Handbook for full details on carrying out gas calibrations.
WARNING
• As some calibration gases may be hazardous, always ensure that outlets from gassing accessories exhaust safely.
• A cylinder of synthetic air (20.9 % vol. oxygen) should be used to perform the zero calibration if there is any doubt that the
atmosphere in which the detector is exposed may contain any trace of detectable gas.
