M25 or 3/4” NPT gland entry or conduit. The allowable conductor size for the terminals is 0.2 – 2.5 mm² (24 - 12 AWG). The OELD terminals will accept only wire sizes (solid- core or stranded) in this range. The temperature rating of the conductors should be greater than 80°C. The terminals should be tightened to a torque of between 0.5 Nm to 0.6 Nm.
It should not be connected to internal earth point. • OELD features internal and external earth points with a clamp size of 8 mm x 8 mm. For the internal earth, use a wire size of 2.5 .
Refer to section 10 for full details on the OELD menu system. 5.1.1 Threshold for Local Alarm Indication The gas reading at which the OELD indicates an alarm (flashing red lights) can be set between 5 and 65 % FSD. The default setting is 20 % FSD.
The detector generates a mA output in relation to the measured gas value. This mA output is monitored by the OELD and is used to provide an indication of the status of the detector which can include warning, fault and inhibit. The mA input to the OELD can be configured to match the mA output profile of the detector to control the OELD backlight function and show messages on the OELD display.
During the connection, the blue light of the OELD will indicate different states. Once the connection has been successfully established and if the detector 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.
The start-up and self-test sequence of the OELD takes approximately 60 seconds. During this time the user can check that each of the functions listed below are operating correctly as well as the OELD checking the correct operation of its critical circuits and processes.
Note The visual indicator of the OELD is derived from the 4-20 mA output of the detector and/or status of the OELD unit� Use a compatible mobile device and the OELD app to connect to the OELD using Bluetooth®� When used in conjunction with a Searchpoint Optima Plus or Searchline Excel, diagnostic and maintenance functions of the detector can be accessed also�...
During normal operation the instrument LCD shows a steady GREEN backlight. In case of a gas alarm or fault the red or yellow backlight respectively will flash. The screen is visible through the window of the OELD top cover and the display shows the gas concentration information both graphically and numerically, as well as other information including full scale range, measurement units, alarm / fault status etc.
6.3 Alternative Communications (SHC-1 Hand-Held Interrogator) If the OELD is being used in conjunction with the Searchpoint Optima Plus or Searchline Excel the detector can be accessed using the Honeywell Analytics SHC-1 Handheld Interrogator and the SHC Protection Device. Use the dedicated terminals inside the OELD to do this.
7.2 Running the OELD Mobile App Note To register a new user account, you will need (1) a connection to the internet and (2) the QR code from at least one OELD device� 1. Find and tap the OELD App icon 2.
7.3 Connecting to OELD Units 1. Standing in proximity to the OELD to which you want to connect, tap on the Detectors button on the main screen of the OELD 2. A list of detectors to which you have access will be shown. Should you require access to a detector that is currently restricted, tap on the device and simply scan the QR code of that device.

8 Maintenance 8 Maintenance 8.1 General Periodically inspect the OELD and cabling for signs of physical damage. Clean the glass window with a damp cloth. Do not use solvents or abrasive cleaners. The OELD has no user serviceable parts. Honeywell Analytics recommend that the unit’s configuration and operation are checked annually as a minimum.
Refer to the detector manual for further information Warn W-03 Warning level input from the detector and possible causes. Reset the OELD. If fault still appears, replace the Comm Err F-01 Internal communication failure display module The connected detector is signaling a F-02 Refer to the detector manual for further information.
Switching between the different modes is achieved through activation of the in-built magnetic switches using the magnetic wand (supplied). Note The magnetic wand will operate the switches through the glass window in the front of the OELD� It is not necessary to open the OELD to operate the switches� 10.1 Abort Function While in Review Mode or Configuration Mode, the user can escape to the previous screen using the Abort Function.
