1 Safety Warnings and Information
WARNING
• Installation must be in accordance with the recognized
standards of the appropriate authority in the country concerned.
For Europe see EN 60079-14 and EN 60079-29-2.
• Do not open the enclosure when energized or when an
explosive atmosphere may be present.
• Operators should be fully aware of the action to be taken if
the gas concentration exceeds the alarm level.
• Do not modify or alter the construction of the product as
essential safety and certification requirements may be
invalidated.
• Access to the interior of the product, when carrying out any
work, must be conducted only by trained personnel.
• Measuring function not approved under ATEX. Do not rely
on the OELD display backlight status indication for safety-
related purposes.
• In order to maintain electrical safety, the unit must not be
operated in atmospheres of more than 21 % vol. oxygen.
2 Installation
Note
When installing the OELD, consider the correct sensor orientation.
Always refer to the sensor manufacturer's instructions.

The OELD may be fixed directly to a suitable flat surface,
using the integral mounting points (dimensions shown).
Ensure that mounting bolts are fully tightened and that
suitable locking washers are used.
Other mounting options are available. Refer to the OELD
Operating Instructions for full details.
OELD carries a rating to IP66 / Type 4X (in accordance with
NEMA 250). Ensure that the environment is suitable for the
OELD.

CAUTION
• Any earthing regime employed must avoid earth loops
The following information is provided to assist with proper
earthing of the OELD:
• The OELD has two internal earth points provided (see
Electrical Connections). This is to facilitate connection of
the sensor to protective earth.
• Field cable screens should be connected to instrument
earth at the control room. The other end of the field cable
screen should be suitably terminated or isolated. It should
not be connected to internal earth point.

Note
The current detection ranges are configurable by the user using the OELD
App or using the magnetic interface. See Operating Instructions for details.
Note
The visual indicator of the OELD is derived from the 4-20 mA output of
the sensor and/or status of the OELD unit. Use a suitable mobile device
and OELD App to connect to the OELD using Bluetooth® to access further
diagnostic information. When used in conjunction with a Searchpoint
Optima Plus or Searchline Excel, diagnostic and maintenance functions of
the sensor can be accessed also.

Note
The OELD has been assessed to ISA 60079-29-1 using the %LEL
units of measurement only. Other units of measurement are not
covered by the approval to ISA 60079-29-1.
7 OELD Mobile App
The OELD provides a wireless interface allowing maintenance
via a Bluetooth® connection. The OELD App can be
downloaded from Google Play Store. An Android smart device
(version 4.3 or above) is required. Contact Honeywell for
details of smart devices suitable for use in the hazardous area.
To use the OELD App:
• Create a User Account linked to an e-mail account.
• Scan the QR code or enter the Device Activation Code
supplied with the OELD and repeat for all devices that
need to be connected to Tap on the Detector button to
scan for nearby devices
• Select and confirm the device to connect to.
The OELD Mobile App supports specific functions of
Searchpoint Optima Plus and Searchline Excel. When one
of these detector types has been connected, full access to
menus related to these specific functions will be possible.
Please refer to the OELD Mobile App manual for full details.
