Site selection and positioning
The placement of gas detectors should follow the recommendations of gas diffusion experts, process equipment experts, safety personnel, and engineering personnel, and record the protocol for determining the detector location.
Installation designers should refer to IEC/EN 60079-29-2 and other national practice standards, as well as the site selection recommendations for specific locations in the gas detector technical manual.
Mechanical Installation
OELD can be installed in various ways through integrated mounting pads, such as on flat walls Unistrut ® On the bracket, use the optional pipe installation kit to install on the pipeline or utility pole, or use the ceiling installation bracket kit to install on the ceiling.
When installing, it is necessary to consider the correct direction of the detector, ensure that the installation bolts are fully tightened, and use appropriate locking washers.
electrical installation
The detector can be installed directly or remotely to the OELD, and some detectors have corresponding junction boxes for remote installation.
The installation steps include removing the cover, taking out the electronic module, installing cable glands or conduit fittings, installing detectors (with different installation methods for different entrance versions), sealing unused cable entrances, making electrical connections, reinstalling the display module and cover, etc.
Electrical connection
Terminal block definition
Terminal block 1 (TB1) and terminal block 2 (TB2) have different markings, colors, and functions for each terminal. For example, terminal 1 of TB1 is – V (black) and is used for auxiliary power supply.
The increased safety (Ex e) version uses terminal blocks of specific manufacturers and types, while the explosion-proof (Ex d) version is black and the increased safety version is green. They must not be mixed, otherwise the product certification will be invalidated.
Wiring diagram
Provided OELD and Searchpoint Optima Plus、Searchline Excel、Searchline Excel Cross-Duct（XD） Wait for the wiring diagram of the detector, as well as the connection method of the detector with the current sink and current source configuration.
Grounding connections should avoid grounding loops. The OELD has two internal grounding points, and the on-site cable shielding layer should be connected to the instrument grounding in the control room. The internal and external grounding points of the OELD have corresponding specifications and connection requirements.
Power supply and cables
The OELD requires a voltage supply of 18-32Vdc (nominal 24Vdc) with a maximum power consumption of 2W, taking into account the voltage drop caused by cable resistance to ensure the minimum required supply voltage at the detector.
The cable should be suitable for hazardous area classification and comply with relevant regulations. It is recommended to use industrial grade shielded field cables. The allowable wire size for terminals is 0.2-2.5mm ² (24-12AWG), and the rated wire temperature should be greater than 80 ° C. The terminal tightening torque should be 0.5Nm to 0.6Nm.
Configuration
Configurable parameters
Including local alarm indication threshold (can be set between 5 and 65% FSD, default 20% FSD), mA input level setting (to match the detector’s mA output curve), and OELD universal display settings (such as full-scale range, measurement unit, gas name, etc.).
configuration process
Configure by running the OELD App on a mobile device, including steps such as launching the application, logging in, searching for nearby OELD units, selecting and confirming connections, etc.
After completing the configuration or changing the settings, the configuration should be read back and verified to ensure that the changes are correct.
Operation
Startup and self-test
The startup and self-test sequence takes about 60 seconds, during which display testing, backlight testing, internal hardware and memory checks, etc. will be performed. After completion, it will enter normal operating mode.
normal operation
During normal operation, the LCD backlight indicates the detector status based on the 4-20mA output of the detector, and different current ranges correspond to different backlight colors and flashing states.
The display screen displays gas concentration information (in graphical and numerical form) and other information during normal operation. At low temperatures, the refresh rate of the display screen will automatically decrease. At extremely low temperatures, the screen clarity may decrease, but it can return to normal after the temperature is restored.
communication model
Equipped with Bluetooth Low Energy (BLE) interface, it supports non-invasive connection with mobile devices running the OELD App, and can also communicate with specific detectors through RS-485 interface.
Honeywell Analytics SHC-1 handheld interrogator and SHC protection device can also be used to connect with relevant detectors, but attention should be paid to relevant warnings and precautions.
