Note: OELD is reverse polarity protected.
Spare conductors must be terminated in a spare terminal. Wiring must be in accordance with local,
national and/or company regulations. Bare conductors must be avoided.
Refer to individual sensor manuals for sensor wiring details. Specific wiring diagrams for some commonly used sensors are provided in the Appendix.
The mA loop voltage is Max 32 VDC and current is Max 22 mA.
OELD User Manual (3018M5000_1-3)
Revision 1, Issue 3
4.1 Power Supply
OELD requires an isolated voltage supply of 18 - 32 Vdc (nominal 24 Vdc), which is suitably approved
for the region (for example, UL approved). Power consumption is 2 W maximum.
Refer to individual sensor manuals for sensor specific limits and power consumption.
Ensure that the minimum required supply voltage is present at the sensor, taking into account the
voltage drop due to cable resistance.
Note: Make allowance for the insertion loss resistance.
The maximum loop resistance in the field cable is calculated as follows:
𝑅𝑙𝑙𝑙𝑙 =
𝑉𝑐𝑐𝑐𝑐𝑐𝑐𝑐𝑐𝑐𝑐 − 𝑉𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑 𝑚𝑚𝑚
𝐼𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑
4.1.1 Example Cable Length Calculation
Example – OELD with Searchpoint Optima Plus:
Searchpoint Optima Plus requires a voltage supply of 18 – 32 Vdc. Its power consumption is 5 W.
Therefore total power consumption including OELD is 7 W maximum.
The controller is supplying a nominal 24 Vdc (V controller) and the detector minimum allowable voltage is 18 Vdc (V detector min), therefore the maximum allowable voltage drop between the controller
and detector is 6 Vdc; this means a voltage drop of 3 V in each core (+ve core and -ve core).
Power consumption of the detector is 7 W. The current required to drive the detector at the minimum
voltage is (I = P / V), 7 / 18 = 388 mA (I detector).
So, the maximum field cable loop resistance (R loop) = 6 / 0.388 = 15.4 Ί, or 7.7 Ί per core.
The following tables show the maximum cable distances between the controller and OELD with
Searchpoint Optima Plus for different cable options, assuming a voltage drop of 3 V in each core. The
tables are examples only and actual cable parameters and source power supply voltage for the application should be used to calculate the maximum cable distance allowed at the installation site.
Note: Sufficient operational margins should be allowed
4.2 Cabling Recommendation
The cable used must be appropriate for the hazardous area classification and meet local, national
and/or company regulations. The use of industrial grade, screened field cable is recommended.
OELD User Manual (3018M5000_1-3)
Revision 1, Issue 3
For example, three-core copper cable with screen (minimum 90% coverage) and suitable mechanical
protection (e.g. steel wire armor) to suit M20 gland entry.
The conductor size for the terminals is 0.2 – 2.5 mm (24 - 12 AWG). The OELD terminals will accept
only copper wire sizes in the range 0.2 – 2.5 mm (solid core), 0.2 – 2.5 mm (stranded core), or 24 –
12 AWG and temperature rating of conductor is greater than 80°C. The terminals should be torqued
to 5.5kgf.cm (5 lb-in).
Ensure the cable gland is installed correctly and fully tightened. All unused cable/conduit entries must
be sealed with a suitable certified blanking plug.
4.3 Earth Regimes
Caution: Any earthing regime employed must avoid earth loops.
The following information is provided to assist with proper earthing of OELD:
• OELD has a continuity plate which is in contact with the internal earth points provided (see Electrical
Connections). This is to facilitate connection of the sensor to protective earth.
• Locking rings are supplied which can be used to connect a sensor body or cable gland to the continuity plate where necessary.
• Field cable screens should be connected to instrument earth at the control room. The other end of
the field cable screen may be terminated in a spare terminal of OELD. It should not be connected to
the continuity plate.
4.4 Fix the 4-20mA Input
After electrical commission it is recommended to calibrate current input to OELD by using mobile
device.
The electrical adjustment procedure is as follows.
1. Short or open the current input ports at the OELD
2. Carry out mA input calibration with mobile device (Configure->Local display->Calibrate mA
input)
3. Re-wire the current input (mA)
For more information please refer to 7 OELD Mobile App
OELD User Manual (3018M5000_1-3)
Revision 1, Issue 3
5 Configuration
5.1 General
OELD has several configurable parameters, which are set using mobile device only. These are the
threshold for local alarm indication, mA input level settings, RS485 communication settings, confidence signal of the green light and sensor settings such as full scale range, measurement unit and
gas name.
1. Threshold for local alarm indication
The gas reading at which OELD indicates an alarm (flashing red lights) can be set between 10 and 65
%FSD. The default setting is 20 %FSD.
Note: This setting is local to OELD and applies only to the red lights in the OELD backlit. Changing
the level will have no effect on alarm levels configured in the sensor, or in the control room.
2. mA input level settings
The sensors transmit specific mA output to indicate the sensor status. The mA input to OELD can be
determined to specific sensor status according to the configured mA input level settings. The mA input
settings are sensor status (warning, fault or inhibit) and message on OELD local display. The default
settings are as below.

3. Confidence signal of the green light
The green lights indicating normal operation can be set to confidence signal to indicate OELD is alive
by flashing green lights. The flashing interval is 10 seconds. If set the green backlit will flash every 10
seconds in normal condition
4. Sensor settings
The sensor settings are full scale range, measurement unit, display resolution and gas name. The
sensor settings are used to convert the 4-20mA input to gas concentration and to show it on OELD
LCD.
WARNING
Do not use the OELD LCD backlit status indication for safety-related purposes.

5.2 Configuration Process
Note: Configuration is done by using mobile device only. There is no local interface to configure
OELD.
To configure OELD, it should be connected to mobile device over Bluetooth Low Energy first. The
blue backlit of OELD will flash when a mobile device pairs with OELD so that an operator can easily
find out and identify the target OELD. When OELD is connected to mobile device successfully the
blue backlight will stay on in normal condition. If the sensor is in abnormal condition, appropriate
backlit of OELD will flash according to sensor status instead of indicating BLE connection.

6. Operation
6.1 LCD
6.1.1 Start-up
OELD’s start-up sequence takes approximately 60 seconds depending on the sensor outputs. The
first step of the start-up sequence is LCD and backlit test. During LCD test each segment of LCD will
be on one by one while LCD backlit will flash in various colors. And OELD shows software version
and various configuration information as below. During start-up sequence except LCD test, the green
light will be on. After the start-up period the lights will indicate the sensor output status.
Note: Depending on the duration of the sensor start up routine, the sensor may still be initialising.
Therefore OELD may indicate Fault or Inhibit for a short time before indicating Normal status.

6.2 BLE Communication (Optional)
OELD features an optional BLE interface that allows non-intrusive connection of mobile device to a
sensor that supports RS485 communication. The OELD bridges message transactions between mobile device and sensor by converting the BLE packet to RS485 message and repeating it onto RS485
interface, and vice versa. OELD does not interpret any RS485 messages from mobile device and
sensor.
The BLE interface is accessed by mobile device that supports Bluetooth Low Energy.
Refer to the OELD Mobile App manual for BLE communication information.
Note: The BLE (Bluetooth Low Energy) is different from Bluetooth Classic. Make sure the mobile device has an operating system that supports BLE.
Note: Bluetooth feature should be enabled in the mobile device to allow it to scan BLE devices nearby.
Refer to the Mobile device user’s manual for details of how to use the Bluetooth on the mobile device.
Note: OELD is compatible with the BLE Point-to-Point mode of operation only. If OELD is connected
with one mobile device, it won’t be scanned by other mobile device
If there is no valid BLE communication for 10 minutes, OELD will terminate BLE connection automatically
Note: BLE communication range will vary depending on the field situation and installation location of
OELD. It is recommended to use BLE interface in the line of sight
6.3 Alternative communications (SHC-1)
If the sensor features an RS485 interface (i.e. Honeywell Analytics optical products) this can be accessed using the Honeywell Analytics SHC1 Handheld Interrogator and the SHC Protection Device,
by direct connection to the terminals inside the OELD.
OELD User Manual (3018M5000_1-3)
Revision 1, Issue 3
Note: OELD does not support XPIS terminal. If XPIS terminal is required, an appropriate junction box
should be used instead
WARNING
Do not use BLE communication when the SHC1 Handheld Interrogator is connected to RS485

4.
5.
6.
After connecting to OELD device, go to Calibrate menu on the mobile app
Click on “Zero” button to start zeroing
Mobile app will initiate zero calibration after inhibiting the 4-20mA output of the Optima Plus
After successful zeroing, click on “Span” button to perform span calibration
Apply calibration gas to the Optima Plus
Wait until span calibration is complete
Refer to Optima Plus User’s manual prior to carrying out gas calibration
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
WARNING
As some calibration gases may be hazardous, ensure that outlets from gassing accessories exhaust safely.
WARNING
A compressed air cylinder (20.9%Vol oxygen) should be used to perform the zero
calibration if the area where the detector is located contains any residual amount
of the target gas.

8. Maintenance
8.1 General
Periodically inspect OELD and cabling for signs of physical damage. Clean the glass window with a
damp cloth. Do not use solvents or abrasive cleaners.
OELD has no user serviceable parts. Honeywell Analytics recommend that the unit’s configuration
and operation are checked annually.
The gas detectors connected to OELD should be checked and if necessary zero and span calibrated
by following the procedures detailed in their operating instructions.
8.2 Display Module Replacement
The display module can be replaced, for example in the event of failure of the LCD and backlit.
1. Remove the power from OELD and carefully remove the lid.
2. Lift the handle and take out the internal display module with no strain on the internal cables.
3. Disconnect the all wires from the terminal block at the bottom of display module
4. It is recommended to make a note of the original serial number of display module and mark the
serial number inside the enclosure. Retain a record of the original serial number in the maintenance
record for the installation (refer to IEC/EN 60079-29-2).
6. Connect the all wires to the terminal block of the replacement display module in accordance with
Chapter 4 Electrical Connections.
7. Carefully replace the display module with no strain on the cables.
8. Fully tighten the lid
Caution: Take care to avoid trapping cables when replacing the display module.
Note: The replacement lid will have default settings for the threshold for local alarm indication and mA
input level settings, RS485 communication settings, confidence signal of the green light and sensor
settings. It may be necessary to re-program the configuration by using mobile device.
